Q: i want to remove the columns after colspan in dataTabl How to use colspan in dataTable?
I want the colspan in the uraian column with the condition that if the column after it is zero, then // Add COLSPAN attribute
$('td:eq(3)', row).attr('colspan', 6);
i want to remove the columns after it

Q: Changing array in function in c++ I am learning C++ and confused why a changes occurred in function gets reflected in main. Can anyone say how to change the array in function without reflecting in main module..
thx for the help
#include <iostream>
using namespace std;
void function1(int x[],int n){
for(int i=0;i<n;[enter image description here](https://i.stack.imgur.com/G17A6.png)i++){
x[i]=0;
}
}
int main(){
int n;
cout<<"Enter the number of terms :";
cin>>n;
int a[n];
for(int i=0;i<n;i++){
cin >> a[i];
}
function1(a,n);
//after calling a function
//printing an array declared in main
for(int i=0;i<n;i++){
cout<<a[i]<<endl;
}
return 0;
}
I wrote a code to check the changes of data in main and function module. After calling the function, i thought the data entered to the array before calling the function wouldn't be changed. However, changes in data in function, reflected in main module

Q: Fill in using unique values in pandas groupby df = pd.DataFrame({'value': [1, np.nan, np.nan, 2, 3, 1, 3, np.nan, 3], 'name': ['A','A', 'B','B','B','B', 'C','C','C']})
name value
0 A 1
1 A NaN
2 B NaN
3 B 2
4 B 2
5 B 2
6 C 3
7 C NaN
8 C 3
In the dataframe above, I want to use groupby to fill in the missing values for each group (based on the name column) using the unique value for each group. It is gauranteed that each group will have a single unique value apart from NaNs. How do I do that?

Q: Change the number of digits of p value on a ggsurvfit() graph Using ggsurvfit(), I generated this graph with the following code:
library(ggsurvfit)
survfit2(Surv(time, status) ~ sex, df_colon) %>%
ggsurvfit() +
add_pvalue("annotation", size = 12)
I would like the p value has 2 digits like 0.37. In the document of add_pvalue() function, there is an argument pvalue_fun = format_p. I just do not know how to specify format_p here. Any suggestions would be appreciated.
A: From the docs here and here you can try this:
library(ggsurvfit)
survfit2(Surv(time, status) ~ sex, df_colon) %>%
ggsurvfit() +
add_pvalue("annotation", size = 12, pvalue_fun = \(x) format_p(x, digits = 3))
A: using format() in add_pvalue():
survfit2(Surv(time, status) ~ sex, df_colon) %>%
ggsurvfit() +
add_pvalue("annotation", size = 12
,pvalue_fun = \(pvalue) format(pvalue, digits=2))

Q: How to use a fixed number of multi-processes in python? I want to analyze the results of different benchmark evaluations.
I have many benchmarks, and when running on the server, I want to evaluate 10 in parallel at a time. In my python script, there is a function that does the evaluation.
def load_single_stat(benchmark,prefetcher, retry=False)
But every time the function is called, the execution will continue only if the function returns.
I can write a shell script to run ten python scripts.
for((i=0;i<${#PREFETCH_METHODS[@]};i++))
do
for ((j=1; j<=$BENCHMARK_NUM; j++))
do
sleep 2
array=($(ps -aux | grep -o ${PREFETCH_METHODS[i]}))
echo ${#array[@]}
while [ ${#array[@]} -ge 10 ]
do
sleep 60
array=($(ps -aux | grep -o ${PREFETCH_METHODS[i]}))
done
cmd="python my_script.py ${PREFETCH_METHODS[i]} $BENCHMARK_NUM "
$cmd &
done
done
Can the above work be done in a python script? I can use multiple processes to run functions, but I can't control the number of them running (the server has other users, and I don't want to take up all the resources).
How can I do it more efficiently?
Thanks

Q: How to pass structures to functions without using pointers？ Consider the following program:
#include <stdio.h>
#include <assert.h>
#include <stdlib.h>
#include <string.h>
struct Person {
char *name;
int age;
int height;
int weight;
};
// new
struct Person* Person_create(char *name, int age, int height, int weight)
{
struct Person *who = malloc(sizeof(struct Person));
assert(who != NULL);
who->name = strdup(name);
who->age = age;
who->height = height;
who->weight = weight;
return who;
}
// Delete
void Person_destroy(struct Person* who)
{
assert(who != NULL);
free(who->name);
free(who);
}
// Print
void Person_print(struct Person* who)
{
printf("Name : %s\n",who->name);
printf("\tAge: %d\n",who->age);
printf("\theight: %d\n",who->height);
printf("\tweight: %d\n",who->weight);
}
int main(int argc, char* argv[])
{
// make two people structures
struct Person* joe = Person_create(
"Joe Alex", 32, 64, 140);
struct Person* frank = Person_create(
"Frank Blank", 20, 72, 180);
// print them out and where they are in memory
printf("Joe is at memory location %p:\n",joe);
Person_print(joe);
printf("Frank is at memory location %p:\n",frank);
Person_print(frank);
// make everyone age 20 years and print them again
joe->age += 20;
joe->height -=2;
joe->weight += 40;
Person_print(joe);
frank->age += 20;
frank->weight += 20;
Person_print(frank);
// destory them both so we clean up
Person_destroy(joe);
Person_destroy(frank);
// try to transfer NULL to Person_destroy
// Person_destroy(NULL);
return 0;
}
The above program is correct, but I would like to know how to complete this program without using pointers and malloc function:
1. I want to create the structure on the stack.
2. I don't want to use pointers to pass the structure to other functions.
For the first problem, creating structures on the stack, I think we can use the alloca function.
For the second question, I wonder if it is possible to use reference passing to accomplish this thing.

Q: Do I need to manually disconnect the sender and the response function after the sender being released? In Qt programming, this is a simple tcp server new connection coming code,
void TcpServerTest::onSeverReadyRead(int clientId)
{
qDebug() << clientId;
qDebug() << clientSocket[clientId]->readAll();
}
void TcpServerTest::onNewConnection(/*QTcpSocket* socket*/) {
QTcpSocket* serverRecordClient = server->nextPendingConnection();
static int iClientIdGenerator = 1000;
int iClientId = iClientIdGenerator++;
clientSocket.insert(iClientId, serverRecordClient);
connect(serverRecordClient, &QTcpSocket::readyRead, [this, iClientId](){
onSeverReadyRead(iClientId);
});
}
When a new connection is coming, onNewConnection will be triggered and we bind a network data process function onSeverReadyRead(iClientId) with this client -- serverRecordClient.
I think when the client disconnect from the server, do I need to explicitly disconnect the binding too?
disconnect(serverRecordClient, &QTcpSocket::readyRead)

Q: CS50 readability - calculation is off I am doing CS50 Readability problem set. I am trying to count the words in a given passage. When I code the calculation within main I get the correct answer:
#include <cs50.h>
#include <stdio.h>
#include <ctype.h>
#include <string.h>
#include <stdlib.h>
#include <math.h>
int letters;
int main(void)//
{
// user prompted for input
string input = get_string("Input: "); //prompt user to input text
for (int i=0; i < strlen(input); i++)
{
if (isalpha(input[i]))
{
letters++;
}
}
printf("letters %i\n", letters);
}
But when I do the calculation outside of main it returns 0. I cannot see why this is happening
#include <cs50.h>
#include <stdio.h>
#include <ctype.h>
#include <string.h>
#include <stdlib.h>
#include <math.h>
int count_letters(string input);
int letters;
int main(void)//
{
// user prompted for input
string input = get_string("Input: "); //prompt user to input text
printf("Letters: %i\n", letters);
}
int count_letters(string input)
{
letters = 0;
for (int i = 0; i < strlen(input); i++)
{
if (isalpha(input[i]))
{
letters++;
}
}
return letters;
}
A: You didn't not call your count_letter function in the second program in the main. So that the letters variable is not calculated. You just defined your function on your top of the program. Make sure to call your function
int main(void)//
{
// user prompted for input
string input = get_string("Input: "); //prompt user to input text
// Called your function here
printf("Letters: %i\n", count_letters(input));
}
A: Your second program doesn't actually call the function. Add:
letters = count_letters(input);

Q: How can I configure specific domain request to local proxy in axios? I have an axios (a nodejs module) requesting a specific domain via https. However, I can not access the domain directly on this server.
So, I use gost to set up a tunnel, connecting to another server that can visit the specific domain. Gost also enables me to listen a local port, and handle the tunnel automatically. Now I have a local proxy with port 8123 that can visit the specific domain. I use the following command to double check that the proxy works:
curl --proxy localhost:8123 'https://api.myip.com/'
Now, the question is: How I can let the axios module to visit the specific domain via my local proxy? I can not modify the code of axios module.
I didn't try the env varibles because I don't want all https requests to go through the proxy.
export https_proxy=http://localhost:8123/
I only want the specific domain to go through this proxy.

Q: Why the following two Julia codes gave different answers? Version 1:
A=[1 2;3 4]
for ii in 1:3
B=A
B[:,:]=B[:,:].+1
end
display(A)
Version 2:
A=[1 2;3 4]
for ii in 1:3
B=A
B=B.+1
end
display(A)
Version 1 gives
2×2 Array{Int64,2}:
4 5
6 7
Version 2 gives
2×2 Array{Int64,2}:
1 2
3 4
I think it has to do with reference and copy. In which step is a copy created in version 2? Thank you if anyone could answer.
I expect version 1 and 2 should give identical answers. I looked up the reference manual but still don't understand when a copy is created in version 2.
A: B.+1 creates a copy in both instances. Call this copy X
In version 1, B[:,:]= mutates in-place the data associated with B to be equal to X. It just so happens that the data associated with B is exactly the data associated with A, which is why you see A change.
Version 2 reassigns the variable B itself to instead have its associated data be X rather than A. This is why A does not change.
If you want to avoid creating a copy altogether, you can write this as A .+= 1

Q: How can MongDB make sure that an ObjectID is unique all the time? When adding a document to a collection in MongoDB database, MongoDB will create a long code as a Unique Object ID. But is it unique only for this collection or for all the collections on this planet created by people all over the world all the time until the end of time?
I am just curious to know how unique this line of ID could potentially be.
A: ObjectID is a 96-bit number which is composed as follows:
a 4-byte timestamp value representing the seconds since the Unix epoch (which will not run out of seconds until the year 2106)
a 5-byte random value, and
a 3-byte incrementing counter, starting with a random value.
Therefore, it is impossible for two records to have the same ID even if they are created at the same time.

Q: Local environment .htaccess php not redirecting Am creating a MVC framework and I have a public folder with the HTACCESS file. I want to be able to type for example "localhost/mvc/public/adjoasdjaos" and it should redirect me to the index.php page like "localhost/mvc/public/"
I have made several attempts which I commented out and it hasn't been working.
<IfModule mod_rewrite.c>
DirectoryIndex index.php
# turn on rewriting
RewriteEngine on
# check that the request isn't actually a real file (e.g. an image)
RewriteCond %{REQUEST_FILENAME}\.php !-f
RewriteCond %{REQUEST_FILENAME} !-d
RewriteRule ^([A-Za-z0-9-]+)?$ index.php?url=$1 [L]
# RewriteRule ^(.*)$ /public/index.php [L]
# redirect requests for BLAH to /edit.php?item=BLAH
# RewriteRule ^(.*)$ /public/index.php?url=$1 [L]
</IfModule>
A: It seems like you want to redirect any request that is not a file or directory to the index.php file with the requested URL as a parameter. To achieve this, you can modify your .htaccess file as follows:
<IfModule mod_rewrite.c>
DirectoryIndex index.php
# turn on rewriting
RewriteEngine on
# check that the request isn't actually a real file (e.g. an image)
RewriteCond %{REQUEST_FILENAME} !-f
RewriteCond %{REQUEST_FILENAME} !-d
# redirect all requests to index.php with URL parameter
RewriteRule ^(.*)$ index.php?url=$1 [QSA,L]
</IfModule>
Here, we are using the QSA flag to append any existing query string to the URL parameter. The L flag indicates that this is the last rule to be processed, so no further rules will be applied.
With this configuration, any request that is not a file or directory will be redirected to index.php with the requested URL as the url parameter. For example, localhost/mvc/public/adjoasdjaos will be redirected to localhost/mvc/public/index.php?url=adjoasdjaos.

Q: how to keep user logged in wordpress, through unity? I've a wordpress-based website, with the default register/login forms. I also have a project I'm working on, a game in unity, which has a login form for things like sending the user's highscore and backup their save data.
Issue is, the user is required to insert name and password every time they want to do so currently, and that can be annoying for the user.
I know there's no good way to store the password locally, and that ideally the game would simply store something like a token to use each time it needs to communicate with the server, and the server would store that + username + IP to ensure that the person doing an action IS who they say they are, but I don't want to make an entire new table in my database(since its a webhost with a very limited 1GB of storage for the MySQL) just for that. What could I do?

Q: Why is my second graphics method not being shown in the output? I'm writing code in java to rotate an image around a circle (to create a flower), and I need to print out 6 flowers. When running the first method - redFlowers(g) - it prints out just fine. However, when I try to run the first method after the second - which is orangeFlowers(g) - the second method doesn't get printed out at all. I'm using g2d.rotate() and g2d.translate.
Does anyone know why this is happenning?
Here is my code:
``
public void redFlowers(Graphics g) {
g.setColor(Color.RED);
g.drawOval(80, 330, 65, 63);
g.fillOval(80, 330, 65, 63);
g.setColor(c);
((Graphics2D) g).setStroke(new BasicStroke(4));
g.drawLine(112, 395, 112, 575);
Image im = new ImageIcon("flower1.jpg").getImage();
// g.drawImage(im, 61, 300, 40, 50, null);
Graphics2D g2d = (Graphics2D) g;
g2d.translate(61, 300);
g2d.rotate(-3.14159 / 2); // top left
g2d.drawImage(im, -92, -50, 46, 70, this);
g2d.rotate(3.14159 / 3.5); // middle left
g2d.drawImage(im, -20, -20, 46, 70, this);
g2d.rotate(-3.14159 / 1); // bottom right
g2d.drawImage(im, -22, -181, 46, 70, this);
}
public void orangeFlowers(Graphics g) {
g.setColor(Color.ORANGE);
g.drawOval(280, 330, 65, 63);
g.fillOval(280, 330, 65, 63);
g.setColor(c);
((Graphics2D) g).setStroke(new BasicStroke(4));
g.drawLine(312, 395, 312, 575);
}

I tried rendering this environment with human https://github.com/sryu1/jsbgym
but I keep getting this error. I understand that I can't use pop() with ArtistList but I don't know what is using ArtistList, could someone check my repo and see if there's any solution to that? Thanks :)

Q: What is difference between two formulae? #include <stdio.h>
int main(void) {
int d, i1, i2, i3, i4, i5, j1, j2, j3, j4, j5, first_sum, second_sum, total;
printf("Enter the first single digit : ");
scanf("%1d", &d);
printf("Enter the first group of five digits : ");
scanf("%1d%1d%1d%1d%1d",&i1, &i2,&i3, &i4, &i5 );
printf("Enter the second group of five digits : ");
scanf("%1d%1d%1d%1d%1d",&j1, &j2,&j3, &j4, &j5 );
first_sum = d + i2 + i4 + j1 + j3 + j5;
second_sum = i1 + i3 + i5 + j2 + j4;
total = 3 * first_sum + second_sum;
printf("check digit : %d\n : ", 9 - ((total - 1) % 10)); // 9 - ((total - 1) % 10))
return 0;
}
This is my code and my input is
Enter the first single digit : 0
Enter the first group of five digits : 13800
Enter the second group of five digits : 15173
If I change the formula
9 - ((total - 1) % 10))
into
10 - (total % 10)
then I think in some cases it has different results; if the total is 10, I'll get a different result.
But how do I explain it to someone?
I calculated those on my book, and I was Googling but I have no idea.
A: the two formulas are different there are mathematical laws such as bodmass rule to determine which of addition/substraction/multiplication/division will take place first. over the top of that in c language too there are right and left precedence in c language. however, sometimes wen you get the same answer it is just because of coincidence.
if you could state the exact question about what you are supposed to perform in the code than we can help you provide which is an appropriate formula according to your requirement.

Q: property and setter decorators are not working and I can't figure out why? Hi I am facing an issue while working with @property and @left.setter even when I have the Cable class derived from object.
from port import Port
class Cable(object):
cableNumber = 1
def __init__(self, connLeft = None, connRight = None):
self._left = connLeft if isinstance(connLeft, Port) else None
self._right = connRight if isinstance(connRight, Port) else None
self._cableId = Cable.cableNumber
Cable.cableNumber += 1
def __repr__(self):
outputString = '{} <----({})----> {}'
return outputString.format(self._left, self._cableId, self._right)
@property
def left(self):
return self._left
@left.setter
def left(self, port):
self._left = None
if isinstance(port, Port):
self._left = port
port._cable = self
#@property
def right(self):
return self._right
#@right.setter
def setRight(self, port):
self._right = None
if isinstance(port, Port):
self._right = port
port._cable = self
In the main.py file:
from port import Port
from cable import Cable
from switch import Switch
p1 = Port('Gi', 1, 1, 0)
p2 = Port('Gi', 4, 12, 0)
c1 = Cable()
print(repr(p1))
print(repr(c1))
print(repr(p2))
print()
c1.left(p1) #Throws error with this
c1.setRight(p1) #Works
I get the following error with c1.left(p1)
Traceback (most recent call last):
File "blablabla", line 18, in
c1.left(p1)
TypeError: 'NoneType' object is not callable
I've been trying to get this working, but no luck. I'll really appreciate your help.

Q: Check if lat/lng are within an area I am trying to find a way of checking if a pair of lat/lng coordinates are within an area (generated by other lat/lng coordinates).
For example, if my area is a rectangle generated with these coordinates:
43.672162
-79.43585
43.629845
-79.314585
And I wanted to check if these coordinates are within that area:
43.651989
-79.371993
I have tried using this package but I can't make it work: github.com/kellydunn/golang-geo
p1 := geo.NewPoint(coords[0].LatX, coords[0].LonX)
p2 := geo.NewPoint(coords[0].LatY, coords[0].LonY)
geo.NewPolygon(p1, p2)
I was wondering if anyone has an implimentation of this they can share, or any resources that can point me in the right direction? I am open to using google maps API as well.
A: It’s just a math, compare coordinates.
If A coordinate inside of a rectangle, then A.x must be less then rect.x1 and greater then rect.x2 or otherwise. And similar algorithm to the y coordinates.
A: I don't know Go, but you can use the cross product to determine if your point of interest is on the left or right of a vector. The vector can be p1 -> p2, then p2 -> p3, etc. If all of them are on the same side then the point sits inside your polygon shape.
Keep in mind you'll have to account for the earth's meridian and possibly other things.
This also assumes your polygon points form a convex shape (of a hull). If it is not a hull, then it may be more difficult.
// This is mock code, I dont know Go
// This is a single iteration of a loop
// Vector p1->p2
vx1 = p2.lat - p1.lat
vy1 = p2.long - p1.long
// Vector p1->pm
vx2 = pm.lat - p1.lat
vy2 = pm.long - p1.long
// Cross product
crp = vx1*vy2 - vx2*vy1
if(cpr > 0){
// main point sits to the left of vector p1->p2
if(first_iteration){
left_side = true
first_ieration = false
} else {
// check if also left side, if true continue, if false return false
if(! left_side){
return false
}
}
} else {
// main point sits to the right (or on the line) of vector p1->p2
if(first_iteration){
left_side = false
first_ieration = false
} else {
if(left_side){
return false
}
}
}
// outside loop, at the end of method
return true

Q: Python Tkinter Combobox Does not Filter Values Properly From the below mentioned code I expect to get 3 fields, where I choose value from the first field, and according to that, values in other two fields should get updated accordingly (All the data is in the database). When I run the code and choose the value combobox_var.get() always returns an empty value and cannot figure out what is wrong and why does this happen. Here is the part of the code (This is part of the larger code, but I believe error is somewhere here):
#connection to postgre database
conn = psycopg2.connect(
host="",
database="",
user="",
password="")
conn.autocommit = True
cursor = conn.cursor()
cursor.execute('''SELECT * from company_code''')
company = cursor.fetchall()
company = pd.DataFrame(company)
company.columns = ['name', 'code', 'bank_account']
# Create the form input fields
legal_entity_id_frame = tk.Frame(upload_root)
legal_entity_id_frame.grid(row=1, column=1, padx=10, pady=10, sticky="WE")
entry1 = tk.Entry(legal_entity_id_frame, font=('bold', 15))
entry1.pack(side="left", expand=True, fill="x")
account_number_frame = tk.Frame(upload_root)
account_number_frame.grid(row=2, column=1, padx=10, pady=10, sticky="WE")
entry2 = tk.Entry(account_number_frame, font=('bold', 15))
entry2.pack(side="left", expand=True, fill="x")
# Define function to update entry widgets based on combobox selection
def update_entries(*args):
print("combobox_var:", combobox_var.get())
selected_value = combobox_var.get()
print("Selected value:", selected_value)
# Check if a selection has been made before attempting to update entries
if not selected_value:
print("No selection has been made")
return
filtered_company = company.loc[company['name'] == selected_value]
if filtered_company.empty:
entry1.delete(0, tk.END)
entry2.delete(0, tk.END)
print("No matching row found in company dataframe")
else:
entry1.delete(0, tk.END)
entry1.insert(0, str(filtered_company.iloc[0]['code']))
entry2.delete(0, tk.END)
entry2.insert(0, str(filtered_company.iloc[0]['bank_account']))
print("Entry widgets updated successfully")
legal_entity_frame = tk.Frame(upload_root)
legal_entity_frame.grid(row=0, column=1, padx=10, pady=10, sticky="WE")
#options = company['name'].astype(str).tolist()
options = company['name'].astype(str).tolist()
combobox_var = tk.StringVar(value="Select a value")
combobox = ttk.Combobox(legal_entity_frame, values=options, state='normal', textvariable=combobox_var)
combobox_var.trace('w', update_entries)
combobox.bind("<Return>", update_entries)
combobox.bind("<<ComboboxSelected>>", update_entries)
combobox.pack(side="left", expand=True, fill="x")
I have also separate .py file, where I separately tested how combobox works, and there it works perfectly - It gets values from the DB right, after changing field, other fields get updated immediately, etc. The thing is that, both of the functions is identical, thus I cannot figure out what causes error, when I try to implement it into the program. Here is the separate .py file as well, that works perfectly:
import tkinter as tk
import pandas as pd
from tkinter import ttk
import psycopg2
root = tk.Tk()
root.title("Dataframe Example")
conn = psycopg2.connect(
host="",
database="",
user="",
password="")
conn.autocommit = True
cursor = conn.cursor()
cursor.execute('''SELECT * from company_code''')
company = cursor.fetchall()
company = pd.DataFrame(company)
company.columns = ['name','code','bank_account']
# Create sample dataframe
# Define function to update entry widgets based on combobox selection
def update_entries(*args):
# Get selected value from combobox
selected_value = combobox_var.get()
# Filter company dataframe based on selected value
filtered_company = company.loc[company['name'] == selected_value]
if filtered_company.empty:
# Clear entry widgets if there is no matching row
entry1.delete(0, tk.END)
entry2.delete(0, tk.END)
else:
# Update entry widgets with values from filtered row
entry1.delete(0, tk.END)
entry1.insert(0, str(filtered_company.iloc[0]['code']))
entry2.delete(0, tk.END)
entry2.insert(0, str(filtered_company.iloc[0]['bank_account']))
# Create tkinter window
# Create combobox widget
options = company['name'].astype(str).tolist()
combobox_var = tk.StringVar(value="")
combobox = ttk.Combobox(root, values=options, state='normal', textvariable=combobox_var)
combobox_var.trace('w', update_entries)
combobox.bind("<Return>", update_entries)
combobox.pack()
# Create first entry widget
entry1 = tk.Entry(root)
entry1.pack()
# Create second entry widget
entry2 = tk.Entry(root)
entry2.pack()
root.mainloop()

Q: Removing rows in a pandas dataframe after groupby based on number of elements in the group I'm stuck trying to figure out the following: Given a pandas dataframe, I would like to group by by one of the columns, remove the first row in each group if the group has less than n rows, but remove the first and last row in each group if the group has n or more rows. Is there an efficient way to achieve this?
A: You can achieve this by applying conditional logic like this :
n = 3 # or any other desired value for n
df.groupby('column_to_group_by').apply(lambda x: x.iloc[1:-1] if len(x) >= n else x.iloc[1:])
A: You can use boolean masks:
n = 3
# Conditions
first = df['col1'].ne(df['col1'].shift())
last = first.shift(-1, fill_value=True)
greater = df.groupby('col1').transform('size').gt(n)
# reverse the mask with '~' to keep rows with loc[] instead of using drop()
out = df.loc[~(first | (last & greater))]
Output:
>>> out
col1 col2
1 A 1
2 A 2
3 A 3
4 A 4
7 B 1
8 B 2
9 B 3
12 C 1
13 C 2
15 D 1
>>> df.join(pd.concat([first, last, greater], keys=['first', 'last', 'greater'], axis=1))
col1 col2 first last greater
0 A 0 True False True # drop (first)
1 A 1 False False True
2 A 2 False False True
3 A 3 False False True
4 A 4 False False True
5 A 5 False True True # drop (last & greater)
6 B 0 True False True # drop (first)
7 B 1 False False True
8 B 2 False False True
9 B 3 False False True
10 B 4 False True True # drop (last & greater)
11 C 0 True False False # drop (first)
12 C 1 False False False
13 C 2 False True False
14 D 0 True False False # drop(first)
15 D 1 False True False

Q: Capturing a string only if it's repeating I want to extract a text from a string if and only if it was repeating, for example:
\sqrt{2} \sin{ \sqrt{\pi} \sqrt{x} } \tan{x}
I want to extract only \sqrt{\pi} \sqrt{x} because \sqrt{...} repeated. How can I do that?
I tried a couple of formulas I know and searched online but didn't get anywhere.

Q: why i'm getting AttributeError when using 'enchant.DictWithPWL()' from 'enchant' module? I'm using 'enchant' module. It has an attribute 'DictWithPWL' to add personal word list to exsisting dictionary that is pre-defined. But i'm getting below error:
`
def dictionary_words_finder(word_lst):
meaningful_word = []
# creating a dictionary object for checking a word is in dictionary or not and also adding
# our personal word list from words.txt
eng_dictionary = enchant.DictWithPWL("en_US", 'words.txt')
for word in word_lst:
if not eng_dictionary.check(word):
continue
else:
meaningful_word.append(word)
return meaningful_word`
But i'm getting below error:
AttributeError: module 'enchant' has no attribute 'DictWithPWL'
Please let me know if there any other way for doing this task if you don't have a solution to above problem.
I've installed the 'enchant' module using !pip install enchant. 'Enchant' module got installed successfylly but the problem is not resolved. Also I've search for other methods for doing same task but can't find any such module or methods.
I expect that above written code should not throw 'AttributeError' by making some changes to the above code.
I've also gone through documentation here --> https://pyenchant.github.io/pyenchant/tutorial.html
enchant.DictWithPWL is still in their documentation but can't get where i'm doing it wrong. Please help.
A: You installed the wrong package. The package you're trying to use is named PyEnchant in PyPI. Try uninstalling enchant and installing PyEnchant.

Q: Is an empty class an abstract class? I have an empty class (without attributes and methods), declared without the keyword "abstract" but It has a child class. Is it an abstract class or just a simple parent class.
public class Vehicle{
}
A: An empty class is not necessarily an abstract class.
For a Java class to be abstract, it has to be declared abstract using the abstract keyword.
Here is some documentation on abstract classes from the Java tutorials:
https://docs.oracle.com/javase/tutorial/java/IandI/abstract.html
An abstract class is a class that is allowed to have abstract methods. An abstract method is a method that is declared without an implementation. Any subclass of an abstract class that is not abstract itself must implement the abstract methods.
In the example you gave, the class Vehicle does not have the "abstract" modifier in its class declaration, so the class Vehicle is not abstract.
You might ask, "Why does Java have abstract classes?"
One use case of abstract classes is in the AWT ("abstract window toolkit") framework. The java.awt.Graphics and java.awt.Graphics2D classes are both abstract.
The java.awt.Window class has a paint method that takes a Graphics instance. This method is inherited by java.awt.Frame and also by javax.swing.JFrame.
The Graphics class is often used in applets, AWT applications, and swing applications.
So that's a little extra information on abstract classes.
A: An empty class without any attributes or methods is just a simple class with no functionality. It is not considered an abstract class, even if it has a child class.
To make a class abstract, you need to use the "abstract" keyword in the class declaration. An abstract class is one that cannot be instantiated directly, and it serves as a base for other classes to inherit from.
In summary, the class "Vehicle" in your example is a simple parent class and not an abstract class.

Q: alternate of indexof in javascript to find items? I have set of paths in a array .So some path are constants and some paths are dynamic .
constant path mean Example "/booking-success"
Dynamic path mean Example '/arrival/view/:job_order_number' --> here job_order_number is dynamice. so /arrival/view/123 , /arrival/view/456.
I need to check whether url present or not .I am trying like this
const children = [
'/booking-success',
'/back-request',
'/arrival/view/:job_order_number'
]
let path = "/booking-success";
// outout true ----> correct
console.log(children.indexOf(path) !=-1)
let path1 = "/arrival/view/1233";
// outout false ----> wrong
// expected true
console.log(children.indexOf(path1) !=-1)
I am not getting expected output.expected output is true which method I can you ?
A: You could use findIndex for this, comparing paths by splitting them on / and comparing each individual element and the overall length of the path, allowing path elements which start with : to match anything:
const children = [
'/booking-success',
'/back-request',
'/arrival/view/:job_order_number'
]
const findChild = (path) => children
.findIndex((child, _, arr) => {
childParts = child.split('/')
pathParts = path.split('/')
return childParts.every((v, i) => v[0] == ':' || v == pathParts[i]) &&
childParts.length == pathParts.length
}) !== -1
paths = [
"/booking-success",
"/arrival/view/1233",
"/arrival/jobs/1233",
"/booking-success/1234",
"/departure/view/1233",
"/arrival/view",
"/back-request"
]
paths.forEach(p => console.log(`${p} : ${findChild(p)}`))

Q: Merge two wave files as bytes, so they play at the same time in Python? I'm making a Discord bot, and I need to record audio from a voice channel and produce one single wave audio file, where all the audio is playing at the same time, like the Discord client hears when others are in the channel. I'm using the Pycord library, and all the audio files are sent as separate users. The closest I've got to the result that I want is the code below, which just overlays one onto another, so you can only really hear one audio stream at a time. I want to be able to hear every audio stream at once (This code was generated with the help of ChatGPT, by the way).
async def after_recording(self, sink: discord.sinks.WaveSink, channel: discord.VoiceChannel):
audio_segments = []
for audio_data in sink.audio_data.values():
audio_data.file.seek(0)
audio_segments.append(AudioSegment.from_file(audio_data.file))
# Determine the maximum duration of the audio files
max_duration = max([len(segment) for segment in audio_segments])
# Pad the shorter audio files with silence
for i, segment in enumerate(audio_segments):
if len(segment) < max_duration:
audio_segments[i] = segment + AudioSegment.silent(duration=max_duration - len(segment))
# Overlay the audio files
overlaid_segment = audio_segments[0]
for segment in audio_segments[1:]:
overlaid_segment = overlaid_segment.overlay(segment)
# Export the overlaid audio to a BytesIO object
overlaid_bytes = BytesIO()
overlaid_segment.export(overlaid_bytes, format='wav')
overlaid_bytes.seek(0)
# Send the overlaid audio as a message attachment to the specified channel
await channel.send(file=discord.File(overlaid_bytes, filename='overlaid_audio.wav'))
# Cleanup
for audio_data in sink.audio_data.values():
audio_data.file.close()
NOTE: While this code was generated with ChatGPT, I looked it over and made edits multiple times. Answers such as this were the only similar answers I could find anywhere as well, it's not generated by it alone.

Q: How to run apache beam dataflow pipeline synchronously? Here is the apache beam custom pipeline code (dataflow).
last_sync_data = (
p | "Read last sync data" >> ReadFromBigQuery(
query='SELECT MAX(time) as last_sync FROM '
'[wisdomcircle-350611:custom_test_data.last_sync]')
| "Extract last sync time" >> beam.Map(lambda elem: elem['last_sync'])
)
p = beam.Pipeline(options=options)
wisgen_data = p | "wisgen job" >> ReadFromJdbc (
jdbc_url=jdbc_url,
username=username,
password=password,
driver_class_name='org.postgresql.Driver',
query="""SELECT users.id AS user_id, CONCAT(users.first_name,' ', users.last_name) AS full_name""",
table_name="users"
)
recruiter_data = p | "recruiter job" >> ReadFromJdbc(
jdbc_url=jdbc_url,
username=username,
password=password,
driver_class_name='org.postgresql.Driver',
query="""SELECT users.id AS user_id, '""",
table_name="users"
)
wisgen_data | "Convert TableRow to dict(wisgen data)" >> beam.Map(
lambda row: row._asdict()
) | "Write to BigQuery in wisgen data table" >> WriteToBigQuery(
wisgen_table,
write_disposition=beam.io.BigQueryDisposition.WRITE_APPEND,
create_disposition=beam.io.BigQueryDisposition.CREATE_IF_NEEDED,
schema='user_id:INTEGER,full_name:STRING)
recruiter_data | "Convert TableRow to dict(recruiter data)" >> beam.Map(
lambda row: row._asdict())
| "Write to BigQuery in recruiter data table" >> WriteToBigQuery(
recruiter_table,
write_disposition=beam.io.BigQueryDisposition.WRITE_APPEND,
create_disposition=beam.io.BigQueryDisposition.CREATE_IF_NEEDED,
schema='user_id:INTEGER,full_name:STRING'
)
_ = (p
| "Create current timestamp" >> beam.Create([{'time': datetime.datetime.utcnow()}])
| "Write to last_sync" >> WriteToBigQuery,
last_sync_tab
schema='time:TIMESTAMP',
write_disposition=beam.io.BigQueryDisposition.WRITE_TRUNCATE,
create_disposition=beam.io.BigQueryDisposition.CREATE_IF_NEEDED,
)
The pipeline operates asynchronously or completes all job operations in parallel, but I want to first execute the starting job last_sync_data (which is written at the beginning of the above code), then just the jobs below should run, and at last, my timstamp (which is written at the end of the above code) job should run when all the above operations are finished.
Can somebody assist me in rewriting the code I have above to meet my needs ?

Q: Cyrillic text in Java I'm trying to transfer Russian text to an Excel or SQlite or to any other program. The result is always the same: Абиссинская кошка.
I understand that something with the encoding.
Tried
String myString = "some cyrillic text";
byte bytes[] = type.getBytes("UTF-8");
String value = URLEncoder.encode(new String(bytes, "Windows-1251"), "Windows-1251");
but that doesn't help either.
Help me to understand. I am newbie.
A: String myString = "some cyrillic text";
byte bytes[] = type.getBytes("UTF-8");
Now bytes contains a UTF-8 encoding of the string. If you were to call new String(bytes, "UTF-8") you would get back an equivalent string to the original one.
But ...
String value = URLEncoder.encode(
new String(bytes, "Windows-1251"), // HERE
"Windows-1251");
... at HERE you are decoding with the wrong character encoding. The String constructor takes your word for it ... and the result is mangled characters.
Understand this:
The bytes array contains just the encoded text. It doesn't contain anything to identify the encoding scheme. So the String constructor has no way of knowing what the correct encoding is ... apart from what you tell it. And it has no (reliable) way of knowing if the encoding you told it is correct. Let alone fixing your mistake.
The correct way to do what your code does is this:
String myString = "some cyrillic text";
String value = URLEncoder.encode(myString, "Windows-1251");
However ... we don't have sufficient context to know whether that is what is actually required for your application.

Q: Why does pdb sometimes skip stepping into multi-part conditional? I have a Minimal Working Example code :
test.py :
a = 4
b = 6
l = [4, 6, 7, 8]
for t in l :
if t == a or t == b:
continue
print(t)
I am stepping through the code using pdb (python-3.9.2) :
local: ~ $ python -m pdb test.py
> test.py(1)<module>()
-> a = 4
(Pdb) b 5
Breakpoint 1 at test.py:5
(Pdb) c
> test.py(5)<module>()
-> if t == a or t == b:
(Pdb) p t,a
(4, 4)
(Pdb) p t == a
True
(Pdb) t == a or t == b
True
(Pdb) n #### <<--- Conditional is True, why doesn't it explicitly step into it?
> test.py(4)<module>()
-> for t in l :
(Pdb) n
> test.py(5)<module>()
-> if t == a or t == b:
(Pdb) p t==a, t==b
(False, True)
(Pdb) t == a or t == b
True
(Pdb) n #### <<--- Conditional is True, and it explicitly steps into it
> test.py(6)<module>()
-> continue
(Pdb) t == a or t == b
True
QUESTION :
*
*Why does pdb explicitly step into the conditional (i.e. it explicitly goes to line 6, the continue statement) when t==b and not when t==a? Is this an optimization?
A: When the t == a check passes, the bytecode jumps straight back to the for line, skipping the continue.
Here's the output you get if you examine the bytecode with dis.dis on CPython 3.9:
1 0 LOAD_CONST 0 (4)
2 STORE_NAME 0 (a)
2 4 LOAD_CONST 1 (6)
6 STORE_NAME 1 (b)
3 8 BUILD_LIST 0
10 LOAD_CONST 2 ((4, 6, 7, 8))
12 LIST_EXTEND 1
14 STORE_NAME 2 (l)
4 16 LOAD_NAME 2 (l)
18 GET_ITER
>> 20 FOR_ITER 30 (to 52)
22 STORE_NAME 3 (t)
5 24 LOAD_NAME 3 (t)
26 LOAD_NAME 0 (a)
28 COMPARE_OP 2 (==)
30 POP_JUMP_IF_TRUE 20
32 LOAD_NAME 3 (t)
34 LOAD_NAME 1 (b)
36 COMPARE_OP 2 (==)
38 POP_JUMP_IF_FALSE 42
6 40 JUMP_ABSOLUTE 20
7 >> 42 LOAD_NAME 4 (print)
44 LOAD_NAME 3 (t)
46 CALL_FUNCTION 1
48 POP_TOP
50 JUMP_ABSOLUTE 20
>> 52 LOAD_CONST 3 (None)
54 RETURN_VALUE
Note that for the t == a comparison,
5 24 LOAD_NAME 3 (t)
26 LOAD_NAME 0 (a)
28 COMPARE_OP 2 (==)
30 POP_JUMP_IF_TRUE 20
the code jumps to the instruction at bytecode index 20, which is the FOR_ITER instruction. The continue line is skipped entirely.
On the other hand, if the t == a check fails and the t == b check passes, then the code falls through the POP_JUMP_IF_TRUE for the first comparison (because the first result is false) and the POP_JUMP_IF_FALSE for the second comparison (because the second result is true). The code ends up reaching this instruction:
6 40 JUMP_ABSOLUTE 20
which is what the continue on line 6 compiles to.
On Python 3.10, the jump targets are different. On 3.10, we instead see
5 24 LOAD_NAME 3 (t)
26 LOAD_NAME 0 (a)
28 COMPARE_OP 2 (==)
30 POP_JUMP_IF_TRUE 20 (to 40)
with the POP_JUMP_IF_TRUE now jumping to bytecode index 40, which is the continue. Thus, on 3.10, pdb now stops at the continue even when t == a. (Due to changes in instruction encoding, bytecode index 40 happens to be represented by an oparg of 20 on Python 3.10, which coincidentally happens to be the bytecode index the Python 3.9 bytecode was jumping to. This confused me for a while before I figured out what was going on.)

Q: Sum values from different objects - javascript I am trying to sum values from different objects. Each object has its ID, but the IDs can repeat in some objects. What I need to do now is sum the values from the objects that have the same ID.
Does someone have an idea for me? I tried to use mongoose aggregate, but with no success.
Let's suppose I have the objects below.
const array = [
{ _id: "123456", value: 30 },
{ _id: "123456789123456789", value: 12 },
{ _id: "123456", value: 25 },
];
I would need something that brings up the following result:
==> id: 123456
value: 55
==> id: 123456789123456789
value: 12
A: Reduce the array into a map. Conveniently, map.set returns the map, so it's just a one-liner.
const array = [{ _id: "123456", value: 30 }, { _id: "123456789123456789", value: 12 }, { _id: "123456", value: 25 }];
const sums = array.reduce((map, object) => map.set(object._id, map.get(object._id) ?? object.value), new Map());
console.log(sums.get("123456"));
console.log(sums.get("123456789123456789"));
// convert to normal object
const sumsAsNormalObject = Object.fromEntries([...sums.entries()]);
console.log(sumsAsNormalObject);
Confused about syntax? See nullish coalescing and spread syntax. You can also convert the map into a plain object if you wanted to.
A: its impossible to have duplicate _id in mongodb, but you can change that to something like dataId, id or else
example:
[
{
_id: 1,
id: 123456,
value: 30
},
{
_id: 2,
id: 123456789123456789,
value: 12
},
{
_id: 3,
id: 123456,
value: 25
}
]
then with wongo would be like:
db.collection.aggregate([
{
"$group": {
"_id": "$id",
"value": {
"$sum": "$value"
}
}
}
])
MONGO-PLAYGROUND
Note: if some data can be handle by resources/database, use it instead. otherwise, create a function to handle it.
A: For each object, it checks whether the "result" object already has a property with the same _id as the current object being looped over.
const array = [
{ _id: "123456", value: 30 },
{ _id: "123456789123456789", value: 12 },
{ _id: "123456", value: 25 },
];
const result = {};
array.forEach(item => {
if(result[item._id]) {
result[item._id] += item.value;
} else {
result[item._id] = item.value;
}
});
console.log(result);

Q: Memory limit issue, nodejs + axios i have a funtion to get title of a webpage and send it back to user but after getting requests for while i can notice the memory is getting piled up. can someone check this and see if there is an issue here or not or if there a better way to get the same result?
thank you
const axios = require("axios");
let cheerio = require("cheerio");
app.get("/title/*", (req, res) => {
let url = req.originalUrl.substr(7);
axios
.get(url)
.then((axi_res) => {
var $ = cheerio.load(axi_res.data);
var title = $("title").text();
title = removeYT(title);
res.send('SUCCESS-'+title);
})
.catch((error) => {
console.error(error);
res.send("SUCCESS-no-title");
});
});
function endsWith(str1, str2) {
if (str1.indexOf(str2) == str1.length - str2.length) {
return true;
} else {
return false;
}
}
function removeYT(title) {
let yt = "- YouTube";
if (endsWith(title, yt)) {
return title.substr(0, title.length - yt.length);
} else {
return title;
}
(memory will be cleaned up but its not that quick, it will be like 5-6 requests can occupy about 90mb and i have to wait for 1-2min for that memory to be freed again although the result is sent back in less than 1sec. so having more requests can make me rich the memory limit restriction before the memory is clear again)

Q: How do I determine if an emit is defined? I have a button that can handle something with and without longPress.
Originally before I switched to emitters I used function callbacks since I had a React Native background.
So I did the typings as
export type UsePressableEmits =
| {
(e: "press", event: Event): void;
(e: "longPress", event: Event): void;
}
| {
(e: "press", event: Event): void;
};
Right now this code block fails
function fire(event: Event) {
firing.value = true;
emit("press", event);
firing.value = false;
}
function fireLongPress(event: Event) {
firing.value = true;
emit("longPress", event); // does not pass type checks
firing.value = false;
}

Q: How do you Get data from fs.readFile? function LoadMapFromText(route){
var str = '';
fs.readFile(route, (err, data) => {
str = data.toString();
});
var pairs = str.split("-n");
console.log(str);
}
ive been trying to fix this problem for god knows how long, and i just don't know how to do it. the string is not updating from inside the arrow function.
i already tried making the function async, and i already tried putting await before fs.readFile, but to no avail. i am at a loss of what to do.
A: The problem is that fs.readFile is an asynchronous function that implements a callback function. The callback function gets executed only after the file has been read. In your case, your "arrow function" is the callback function, which gets executed only after the file has been read. But by this time, the lines following the callback, including your console.log(str) statement, have already been executed.
Try using fs.readFileSync instead.
function LoadMapFromText(route){
var str = fs.readFileSync(route, 'utf8');
var pairs = str.split("-n");
console.log(str);
}
A: You should use the function fs.readFileSync()
in the proposed case if it is a light file, otherwise you should use the callback of fs.readFile with a promise, so your string was not updated.
function LoadMapFromText(route){
let str = '';
str = String(fs.readFileSync(route))
var pairs = str.split("-n");
console.log(str, pairs);
}

Q: Find ideal window of values in pandas dataframe column using rolling window I have the following dataframe:
df =
col_1 col_2 col_3
1 5.6 2.1
2 4.3 2.3
3 6.2 2.25
4 5.2 2.15
5 4.7 2.11
6 5.1 2.10
7 4.4 2.24
8 6.1 2.12
Is there a way I can use pandas rolling or another function/technique to find a consecutive set of 3 or X number of rows based on col_3 where the values are stable (i.e. within a range of 0.05 from one another indicating that each of the samples (i.e. col_1) are showing consistency in results? Essentially specifying a window of stable values based on col_3 to extract and save the window values in a numpy array.
I've tried to simplify if it to look for a set of consecutive values based on col_1 that are between 2.10 and 2.25, but haven't been able to get it to work. Is there a way to ensure the output values are consecutive?
So in the example, I would get back the following as an output:
col_1 col_2 col_3
4 5.2 2.15
5 4.7 2.11
6 5.1 2.10
which I can then concatenate the 3 values in col_3 as an array/list?
A: The output of the rolling function must be a number, so you cannot return a list that is the rolling result into col_3 directly.
You should use window.to_list() to get the windowed value list first and then produce the result.
code:
import pandas as pd
def check_stable(args, thr=0.05, length=3):
if len(args) != length:
return None
if max(args) - min(args) > thr:
return None
return args
windowed = [window.to_list() for window in df["col_3"].rolling(3)]
df["result"] = pd.Series(windowed).apply(check_stable, length=3)
output:

Q: Circlize in R: Multiple group chord diagram Using the package circlize from R, My objective is to be able to group a chord diagram by year within each sector. New to the package, I started from the beginning by following examples in the tutorial. According to the vignette, grouping is possible (even using data.frames) by passing a group flag to the chordDiagram() command. This is stated in Chapter 15.6 Multiple-group Chord diagram. Following the vignette, i was able to produce a chord diagram but I am stuck on how to group to get my desired result. I have put together an example of a visual of what I would like the chord diagram to look like here:
As you can see, I aim to have each sector (OOP, UVA, WSE, FIN, MAT, OIC) grouped by the year (which is a column in the input data.frame. I can get the chord diagram, but without the years added.
A reproducible example
Creating a data.frame
Types <- data.frame(Types = c("OOP", "UVA", "MAT", "OIC", "FIN", "WSE"))
Type_Cols <- c(OOP = "#548235", UVA = "#660066", MAT = "#4472C4", OIC = "#002060", FIN = "#843C0C", WSE = "#C55A11")
stack.df <- data.frame(Year = c(rep(2019, 1), rep(2020, 4), rep(2021, 7), rep(2022, 11), rep(2023, 11)),
Invoice = c(paste0("2019.", "10", ".INV"),
paste0("2020.", seq(from = 20, to = 23, by = 1), ".INV"),
paste0("2021.", seq(from = 30, to = 36, by = 1), ".INV"),
paste0("2022.", seq(from = 40, to = 50, by = 1), ".INV"),
paste0("2023.", seq(from = 50, to = 60, by = 1), ".INV")))
stack.df <- cbind(stack.df, Org_1 = Types[sample(nrow(Types), nrow(stack.df), replace = TRUE), ], Org_2 = Types[sample(nrow(Types), nrow(stack.df), replace = TRUE), ])
Adding lty & colors for links
stack.df$lty <- sample(x = rep(c(1,2), times = nrow(stack.df)), size = nrow(stack.df), replace = TRUE)
stack.df$Link_cols <- stack.df$Year
stack.df$Link_cols <- ifelse(stack.df$Link_cols == 2019, "#D9D9D9",
ifelse(stack.df$Link_cols == 2020, "#B296B6",
ifelse(stack.df$Link_cols == 2021, "#FFD966",
ifelse(stack.df$Link_cols == 2022, "#D5469E",
ifelse(stack.df$Link_cols == 2023, "#B4C2A7", stack.df$Link_cols)))))
Re-arranging the stack.df
stack.df <- stack.df[, c(3,4, 2, 1, 5, 6)]
Graph the Chord Diagram
library(circlize)
chordDiagramFromDataFrame(stack.df[, c(1:2)], order = sort(union(stack.df$Org_1, stack.df$Org_2)),
grid.col = Type_Cols, link.lty = stack.df$lty, directional = 1, direction.type = "arrows",
link.arr.col = c("black", rep("white", nrow(stack.df) - 1)))
This gives the following chord diagram:
To produce the group parameter, the names in group should cover all sector names. This is where I am stuck, the vignette gives an example using a matrix, but not a data.frame. I have attempted to work around this buy writing similar codes like this:
group <- structure(union(stack.df$Org_1, stack.df$Org_2), names = unique(stack.df$Year))
But an approach like this gets me nowhere. Any ideas to get me unstuck? Thank-you!

Q: Look for an excel formula please help me with this problem.
I have this excel sheet and I need to find fastest way to find the solution for my professor's request. I have no clue how to do this. Please help me!!!!
The ranking is based on the importance of the status.
I need to identify which one of the duplicates is considered as "GOOD" and the other as "BAD" in the result column.
For example: there are two product id are 31 and they have different status, one is Contacts Activities Opportunity and one is Contacts Activities. Between the two product ID, the one with Contacts Activities Opportunity (ranking No.1) is "GOOD" and the one with Contacts Activities (ranking No.4) is "BAD".
Please help me how to put together a formula or a rule to identify which one of the duplicate of Product ID is GOOD or BAD based on the ranking.
This is my spreadsheet
I created the ranking column so I can try to create a formular to identify the result column faster. I had an idea of comparing which product ID has more amount of letters would be considered as "GOOD" in the result column. But I don't know how to work it out within Excel.

Q: why line plot change when I combine them using ggplot? I have these 3 datasets for three different disease groups with a health score. When I combine them in one dataset and plot them, they appear differently compared to their individual plots (as shown below).
After adding a variable called "disease" in each of them "healthy, HF, stroke", I combined the three datasets this way
d1<- rbind(healthy_clean,HF_clean, Stroke_clean)
then I checked the number of individuals in the new dataset (d1) compared to the original and they were the same. Also, I checked the mean, SD, max and min of the health score for each disease group in d1 and they were exactly as in the original.
any idea why it is not the same lines on the overall line plot?
this is my code for the separate plots and the combined one
#####example of separate:
ggplot(data=healthy_clean, aes(x=age, y=Mental.Health_T.score,fill=Gender, linetype=Gender)) +
geom_smooth(alpha=0) +
scale_x_log10() +
scale_y_log10() +
xlab("Age (Years)") +
ylab("Health Global Score")+

Q: Trouble solving captcha on Discord guild join using discord.py-self and capmonster. Error: 400 Bad Request: Captcha required I'm trying to solve a captcha on Discord guild join using discord.py-self and capmonster. However, I keep getting the following error:
selfcord.errors.CaptchaRequired: 400 Bad Request (error code: -1): Captcha required
Here is the code I'm using:
class CaptchaSolver(selfcord.CaptchaHandler):
async def fetch_token(self, data: dict, proxy: str, proxy_auth: aiohttp.BasicAuth) -> str:
async with aiohttp.ClientSession() as session:
capmonster = HCaptchaTask("")
task_id = capmonster.create_task("https://discord.com/", data['captcha_sitekey'])
result = capmonster.join_task_result(task_id)
return result.get("gRecaptchaResponse")
I've tried changing the URL in the create_task method to "https://discord.com/channels/@me", and also passing a user_agent with rqdata. However, neither of these solutions seem to have resolved the issue.
I was expecting the code to successfully solve the captcha and return the gRecaptchaResponse token, but instead I'm still receiving the selfcord.errors.CaptchaRequired: 400 Bad Request (error code: -1): Captcha required error.
I'm not sure what's causing the error or how to solve it. Any help would be appreciated. Thanks in advance!

Q: JwtStrategy class is not working for cognito access token I'm trying to validate the user access tokens by running them through my JwtStrategy class in nestjs. Besides my approach I've tried quite a few of the tutorial ones with no luck. I keep getting a 401 even when using auth0. My LocalStrategy works fine and outputs the accesstoken as well as other expected information.
Here is my JwtStrategy class:
import { Injectable, UnauthorizedException } from '@nestjs/common';
import { PassportStrategy } from '@nestjs/passport';
import { Strategy, ExtractJwt } from 'passport-jwt';
import { passportJwtSecret } from 'jwks-rsa';
@Injectable()
export class JwtStrategy extends PassportStrategy(Strategy) {
constructor() {
super({
secretOrKeyProvider: passportJwtSecret({
cache: true,
rateLimit: true,
jwksRequestsPerMinute: 3,
jwksUri: `https://cognito-idp.${process.env.AWS_REGION}.amazonaws.com/${process.env.AWS_COGNITO_USER_POOL_ID}/.well-known/jwks.json`,
}),
jwtFromRequest: ExtractJwt.fromAuthHeaderAsBearerToken(),
audience: process.env.AWS_COGNITO_CLIENT_ID,
issuer: `https://cognito-idp.${process.env.AWS_REGION}.amazonaws.com/${process.env.AWS_COGNITO_USER_POOL_ID}`,
algorithms: ['RS256'],
});
}
validate(payload: any) {
if (!payload) {
throw new UnauthorizedException();
}
return payload;
}
}
Here is my AuthModule:
import { Module } from '@nestjs/common';
import { JwtStrategy } from './jwt.strategy';
import { LocalStrategy } from './local.strategy';
import { PassportModule } from '@nestjs/passport';
@Module({
imports: [PassportModule.register({ defaultStrategy: 'jwt' })],
providers: [JwtStrategy, LocalStrategy],
exports: [],
})
export class AuthModule {}
This is the endpoint I'm trying to hit:
import { Controller, Get, UseGuards } from '@nestjs/common';
import { AppService } from './app.service';
import { AuthGuard } from '@nestjs/passport';
@Controller()
export class AppController {
constructor(private readonly appService: AppService) {}
@Get()
@UseGuards(AuthGuard('jwt'))
getHello(): string {
return this.appService.getHello();
}
}
This is my jwt auth guard:
import { Injectable } from '@nestjs/common';
import { AuthGuard } from '@nestjs/passport';
@Injectable()
export class JwtAuthGuard extends AuthGuard('jwt') {}
*
*Removing the @UseGuards(AuthGuard('jwt')) line in the intended endpoint yields the expected result
*I tried using tokens/implementations from both cognito and auth0 so I don't believe this is an idp issue
*I verified that this https://cognito-idp.${process.env.AWS_REGION}.amazonaws.com/${process.env.AWS_COGNITO_USER_POOL_ID}/.well-known/jwks.json,
})` indeed produced the correct JSON result
*I have double and triple checked the env variables used in the JwtStrategy class
*The access token is a valid jwt token

Q: How to Remove Lightbox in Blogger? the codes doesnt exist So I want to remove CSS Lightbox from my Blogger but, when I search for the code it's not there. Previously, I deleted it but I don't know why it's back again
screenshoot the lightbox
I've been looking for it on google but nothing, I just want the lightbox to disappear so it can display images immediately. Because the Lightbox itself has a problem where it doesn't display an image, only a black blank.

Q: extracting hour in a 24h format from a dataset hi trying to extract the hour from the column date in a 24h format from the following dataset
and it doesn't seem to work I seem to be getting only am
Chicago crime
df["timestamp"] = pd.to_datetime(df["date"])
# Convert timestamp to AM/PM format
df["timestamp"] = df["timestamp"].apply(lambda x: x.strftime("%Y-%m-%d %I:%M:%S %p"))
df['hour'] = df['timestamp'].dt.hour
The hour part is from 1-12 and I don’t seem to have am/pm only utc in the time stamp
the data in the time stamp column-date
A: Using the following version you can extract the hour from the sample without the need to convert the datatype of entire column.
from datetime import datetime
sample = "2019-08-29 06:40:00 UTC"
parsed_sample = datetime.strptime(sample, "%Y-%m-%d %H:%M:%S %Z")
hour = parsed_sample.hour
Here %Z represents the time zone.

Q: How to 'git cat-file' using exclusively Python? I am trying to read out commit hashes, alongside their parent hashes, in order to build a commit graph from the .git/ directory. Currently, I have something like:
import zlib
import os
...
for current, subs, files in os.walk('.'):
for filename in files:
# in format ##/#{38}
path = os.path.join(current, filename)[2:]
# 'info/' and 'pack/' exist
# don't worry about packed files
# assume empty (excluding . and ..)
with open(path, 'rb') as file:
# returns bytes object
# assuming UTF-8 encoding (default) vs. legacy
# https://git-scm.com/docs/git-commit#_discussion
# .decode() also defaults to utf-8
print(zlib.decompress(file.read()).decode())
However, I am noticing that this is not what I want. The above code is meant to eventually go through all of .git/objects/ and parse into a list the commits and their parents to help me build the commit graph. As of right now, it seems like the zlib decompression is not producing output the way I like. I have read the relevant sections in Pro Git, specifically: http://git-scm.com/book/en/v2/Git-Internals-Git-Objects , which had instructions for Ruby. How can I accomplish this in Python?
A: The linked documentation seems pretty clear.
Git first constructs a header which starts by identifying the type of object — in this case, a blob. To that first part of the header, Git adds a space followed by the size in bytes of the content, and adding a final null byte:
Ruby is very similar to Python, so when the documentation shows:
>> content = "what is up, doc?"
=> "what is up, doc?"
>> header = "blob #{content.bytesize}\0"
=> "blob 16\u0000"
>> store = header + content
=> "blob 16\u0000what is up, doc?"
The Python code is almost identical:
>>> content = "what is up, doc?"
>>> header = f"blob {len(content)}\0"
>>> blob = header + content
>>> blob
'blob 16\x00what is up, doc?'
As both the prose and the code are showing us, when you read data from an object file you need to split it into a header and content. Something like:
with open(path, 'rb') as fd:
data = zlib.decompress(fd.read())
header, content = data.split(b'\0', 1)
if header.startswith(b'commit'):
print('found a commit in', path)

Q: Numpy error after applying pd.convert_dtypes() to dataframe This python code snippet works the way I want it to.
import pandas as pd
import numpy as np
dfn = pd.read_csv("dirtydata.csv")
bike_sales_ds = dfn.copy()
# Create new age column with general age range groups
age_conditions = [
(bike_sales_ds['Age'] <= 30),
(bike_sales_ds['Age'] >= 31) & (bike_sales_ds['Age'] <= 40),
(bike_sales_ds['Age'] >= 41) & (bike_sales_ds['Age'] <= 55),
(bike_sales_ds['Age'] >= 56) & (bike_sales_ds['Age'] <= 69),
(bike_sales_ds['Age'] >= 70)
]
age_choices = ['30 or Less', '31 to 40', '41 to 55', '56 to 69', '70 or Older']
bike_sales_ds['Age_Range'] = np.select(age_conditions, age_choices, default='error')
I tried to add the .convert_dtypes() method as follows and now get this error.
df = pd.read_csv("dirtydata.csv")
dfn = df.convert_dtypes()
bike_sales_ds = dfn.copy()
Traceback (most recent call last):
File "C:\Users\dmcfa\PycharmProjects\Bike Sales Data Cleaning 01\main.py", line 43, in
bike_sales_ds['Age_Range'] = np.select(age_conditions, age_choices, default=0)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
File "<array_function internals>", line 200, in select
File "C:\Users\dmcfa\PycharmProjects\Bike Sales Data Cleaning 01\venv\Lib\site-packages\numpy\lib\function_base.py", line 845, in select
raise TypeError(
TypeError: invalid entry 0 in condlist: should be boolean ndarray
The part I don't understand is that df.info() would imply that convert_dtypes() didn't change the type of the Age column. It was an Int64 before the method and after. Setting convert_integer to false fixes the problem but I don't understand why it should matter.
Can someone explain what is going on behind the scenes in numpy or is this something to do with the pandas inference rules?
A: Your code works fine for me with my input dataframe. However, you can use pd.cut to check if the problem persists:
age_conditions = [0, 30, 40, 55, 69, np.inf]
age_choices = ['30 or Less', '31 to 40', '41 to 55', '56 to 69', '70 or Older']
bike_sales_ds['Age_Range'] = pd.cut(bike_sales_ds['Age'],
bins=age_conditions,
labels=age_choices)
Output:
>>> bike_sales_ds
Age Age_Range
0 87 70 or Older
1 25 30 or Less
2 70 70 or Older
3 55 41 to 55
4 33 31 to 40
.. ... ...
95 89 70 or Older
96 79 70 or Older
97 67 56 to 69
98 71 70 or Older
99 78 70 or Older
[100 rows x 2 columns]
Input:
import pandas as pd
import numpy as np
np.random.seed(2023)
bike_sales_ds = pd.DataFrame({'Age': np.random.randint(0, 100, 100)})

Q: How to reduce CPU usage in listen and handle siutation? I have a process which need to listen and handle.
to be specific, I need to listen from two shared memory, and whenever there are new data arrived. I need to handle it. meanwhile, i don't want one data block the other, so, I let them run in separate thread.
here is a demo code:
void RunFirst() {
while (true) {
std::string s;
shm1_->Recv(&s);
// handle 1
}
}
void RunSecond() {
while (true) {
std::string s;
shm2_->Recv(&s);
// handle 2
}
}
void start() {
std::thread t(RunFirst);
RunSecond();
}
I have two shm object, which are two shared memory Recviver. they loop to listen if there is data.
it runs well which can handle whenever data comes. and wont let one data blocks another.
but the problem is the high CPU usage. it make two CPU runs in 100% usage.
Is there any methods can decrease CPU usage and keep the unblock?

Now when I implemented the base class, I did not plan properly, some algorithms such as KMeans are unsupervised and hence do not need y at all in fit. Now a quick fix I thought of is to type hint y as Optional, so that it can be None, is that okay? In that case, in KMeans' fit method, I will also have to include the y: Optional[T] = None, which will never be used.

Q: Unable to uncheck items in a custom MultiSelectListPreference dialog I have created a custom MultiSelectListPreference where I can handle each item from the list click and save it to shared preferences. If the user selects item 0 or 1 from the list, then I want to unselect all other items from the list. However, when I call listView.setItemChecked(i, false), it doesn't change anything on the list. I have also tried notifyDataSetChanged and invalidate, but still no luck.
Here is the code for the custom MultiSelectListPreference:
import android.content.Context;
import android.content.DialogInterface;
import android.util.AttributeSet;
import android.util.Log;
import android.util.SparseBooleanArray;
import android.widget.ArrayAdapter;
import android.widget.ListView;
import androidx.appcompat.app.AlertDialog;
import androidx.preference.MultiSelectListPreference;
import java.util.HashSet;
import java.util.Set;
public class MultiSelectListPreferenceCustom extends MultiSelectListPreference {
private final String TAG = "Custom Class Dialog";
public MultiSelectListPreferenceCustom(Context context, AttributeSet attrs) {
super(context, attrs);
}
@Override
protected void onClick() {
AlertDialog.Builder builder = new AlertDialog.Builder(getContext());
builder.setTitle(getDialogTitle());
builder.setMultiChoiceItems(getEntries(), getSelectedItems(), new DialogInterface.OnMultiChoiceClickListener() {
@Override
public void onClick(DialogInterface dialog, int which, boolean isChecked) {
Log.d(TAG, "onClick: Which Button == "+which+" "+isChecked);
ListView listView = ((AlertDialog) dialog).getListView();
Log.d(TAG, "onClick: Get Item Count = "+listView.getCount());
if (which == 0 || which == 1) {
// If "Public" or "All Friends" is selected, uncheck all other items
for (int i = 0; i < listView.getCount(); i++) {
if (i != which) {
listView.setItemChecked(i, false);
}
}
} else {
// If any other item is selected, uncheck "Public" and "All Friends"
listView.setItemChecked(0, false);
listView.setItemChecked(1, false);
}
ArrayAdapter adapter = (ArrayAdapter) listView.getAdapter();
adapter.notifyDataSetChanged();
Log.d(TAG, "onClick: list check = "+listView.getCheckedItemPosition());
}
});
builder.setPositiveButton(android.R.string.ok, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// Save selected items
ListView listView = ((AlertDialog) dialog).getListView();
SparseBooleanArray checkedPositions = listView.getCheckedItemPositions();
Set<String> values = new HashSet<>();
for (int i = 0; i < checkedPositions.size(); i++) {
if (checkedPositions.valueAt(i)) {
int position = checkedPositions.keyAt(i);
values.add(getEntryValues()[position].toString());
}
}
setValues(values);
}
});
builder.setNegativeButton(android.R.string.cancel, new DialogInterface.OnClickListener() {
@Override
public void onClick(DialogInterface dialog, int which) {
// Do nothing
}
});
builder.show();
}
}
I have also tried adding the following code after calling listView.setItemChecked(i, false):
((ArrayAdapter) listView.getAdapter()).notifyDataSetChanged();
listView.invalidateViews();
But still, the items are not getting unchecked. Can anyone suggest what could be the issue here? Any help would be appreciated.

Q: XOR implementation using SimpleRNN Keras - not able to acheive 100% accuracy easily I am trying to get 100% accuracy for XOR implementation using SimpleRNN from keras.
However, the accuracy is only able to reach upto 75% most of the time and very rarely reaches 100%
here is the standard code available over the internet & chatGPT
from keras.models import Sequential
from keras.layers import SimpleRNN, Dense
import matplotlib.pyplot as plt
# Define the SimpleRNN model
model = Sequential()
model.add(SimpleRNN(units=2, input_shape=(2, 1), activation='sigmoid'))
model.add(Dense(units=1, activation='sigmoid'))
# Compile the model
model.compile(optimizer='adam', loss='binary_crossentropy', metrics=['accuracy'])
# Define the XOR dataset
X = [[[0], [0]], [[0], [1]], [[1], [0]], [[1], [1]]]
y = [[0], [1], [1], [0]]
# Train the model and record the training history
history = model.fit(X, y, epochs=1000, verbose=0)
# Plot the training loss over epochs
plt.plot(history.history['loss'])
plt.title('Training Loss')
plt.xlabel('Epoch')
plt.ylabel('Loss')
plt.show()
== this one does behave randomly -- and reaching 100% only very few times.
Is there any standard method which can ensure I get 100% every time?
====================================================================

# expected values

print(f'targets data shape: {y.shape}')
# Define a network as a linear stack of layers

Q: React router to redirect new page using a button onClick I'm trying to allow the user to click on the "Sign up" button and be redirected to a completely new page that I can begin styling for a small project but I can't seem to figure out the react-router-dom routing correctly. Inside my App.js the components are rendered on the screen and within the Signup component there are two buttons. One "Sign up" and one "Login". My thinking is that when either button is clicked it should point the user to a new page. However, I see the correct route in the search bar being "http://localhost:5173/signup" when clicked but I do not see a new page which is frustrating because I'm not sure if I'm making the easiest mistake but I can't see it. I followed this code-along but I still couldn't figure out how to replicate it in my own use case for the life of me.
Here is my repo: link
A: I opened your code as you have attached to your question, you might need to change here, Since you have not written any path in the Route, then how would be able to navigate there already, Following solution might help you :
<Routes>
<Route path="/register" element={<Register />}></Route>
<Route path="/signup" element={<SignUp />}></Route>
</Routes>
Here some changings are required too :
<button
onClick={() => navigate("/register")}
</button>
Rest of your code is Fine, Happy Day!

Q: sns sends msg to an sqs but not the other I have 2 sqs queues subscribed to the same sns topic (all 3 resources are in the same account).
One of the sqs queues receives msgs from the sns topic but the other sqs never does.
I checked that the sqs access policies are exactly the same.
What are some ideas to debug the issue?
A: There are a few things you can check to debug this issue.
*
*Check that the subscription for the second SQS queue is active. You can do this by navigating to the SNS topic in the AWS console, selecting the "Subscriptions" tab, and verifying that the subscription is listed and marked as "Confirmed". If it's not confirmed, you may need to follow the confirmation link that was sent to the email address associated with the subscription.
*Make sure that the second SQS queue has the correct permissions and configuration settings to receive messages from SNS. Specifically, check that the SQS queue has a policy that allows the SNS topic to send messages to it. You can also check the queue's settings to ensure that it is configured to receive messages.
*Check the access policy for the SNS topic to ensure that it allows the second SQS queue to receive messages. Specifically, look for any "Deny" statements in the policy that may be blocking the second SQS queue from receiving messages.
*Confirm that the messages are actually being published to the SNS topic. You can do this by navigating to the SNS topic in the AWS console, selecting the "Monitoring" tab, and reviewing the message delivery metrics.
*Make sure that the second SQS queue's message visibility timeout is set high enough to allow it to process messages. If the timeout is set too low, the queue may not have enough time to process messages before they become invisible and are picked up by the first SQS queue.
*You can use CloudWatch logs to see if there are any errors or issues occurring with the second SQS queue. Check the logs for any error messages or warnings that may be related to the issue.

Q: Need values render to view as state changes, but it renders all at once when receiving stream So I have a react app, added the openAI api and receiving results works.
Now I also tried the stream function via server-sent-events and added a button which calls new EventSource(url).
On the server the data gets fetched and I receive the response in chunks, but all in one single string, which I have so split then. These chunks gets send back to the client where each chunk gets saved to the redux store.
On my app I've set useSelector() to get the chunks from state.
There is a useEffect(), which listens to the chunk state and append the chunks (strings) to a useRef(). The value of useRef() gets assigned to a useState().
When I try to render the value of useRef() or useState() to the view the value gets rendered as a whole.
Is there a way to render it word by word?
When I log it to the console I can see on each render the words appending until its finished, but on the app I just see the endresult instant, not word by word.

Q: Can't Override Default Font Globally on MUI Theme Objective:
I'm trying to override the default font using MUI themes.
Problem: After reading MUI documentation, and stack overflow research, I'm unable to override a self hosted font globally across the theme.
Theme file:
import { createTheme } from "@mui/material/styles";
import VCRMonoWoff2 from './fonts/VcrMono.woff2';
import VCRMonoWoff from './fonts/VcrMono.woff';
const theme = createTheme({
typography: {
fontFamily: 'VCRMono',
},
components: {
MuiCssBaseline: {
styleOverrides: `
@font-face {
font-family: 'VCRMono';
font-weight: normal;
font-style: normal;
src: url(${VCRMonoWoff2}) format('woff2'), url(${VCRMonoWoff}) format('woff');
unicodeRange: U+0000-00FF, U+0131, U+0152-0153, U+02BB-02BC, U+02C6, U+02DA, U+02DC, U+2000-206F, U+2074, U+20AC, U+2122, U+2191, U+2193, U+2212, U+2215, U+FEFF;
}
`,
},
},
});
export default theme;
Usage:
import { ThemeProvider } from 'react-bootstrap';
import { CssBaseline } from '@mui/material';
import Box from '@mui/material/Box';
import theme from './theme';
export default function Example() {
return (
<ThemeProvider theme={theme}>
<CssBaseline />
<Box>Example3</Box>
</ThemeProvider>
);
}
This doesn't update my theme typography to the new font. However, if I run this code, the font is updated to VCRMono:
export default function Example() {
return (
<ThemeProvider theme={theme}>
<CssBaseline />
<Box sx={{
fontFamily: 'VCRMono',
}}>Example3</Box>
</ThemeProvider>
);
}
Although, this doesn't meet my objective as I am trying to override the default font globally.
MUI Self Hosted Fonts Documentation states: "you need to change the theme to use this new font. In order to globally define as a font face, the CssBaseline component can be used." I tried replicating these steps and wasn't able to accomplish the task.
Any help is appreciated. Thank you.
A: The code above was correct, although, the root was not wrapped in the ThemeProvider class.
This is the fix:
<React.StrictMode>
<ThemeProvider theme={theme}><Example/></ThemeProvider>
</React.StrictMode>
Wrap ThemeProvider around the root to enforce it globally.
This is present in the documentation around theming.
Although, it's in a different location from typography so I missed it earlier.

Q: How to understand why CloudFront returns 301? I have a distribution in CloudFront pointing to a custom origin. It worked just fine for more than five years and just a few weeks ago started to return 301 for all requests. The origin works as before, SSL certificates are valid both at the CloudFront endpoint and at the origin. The configuration of the "behavior" I didn't change in CloudFront. What could be the problem and how can I understand where is it?
If it helps, here is the URL: https://djk1be5eatcae.cloudfront.net/?u=https://www.yegor256.com/index.html. The origin that it points to is relay.jare.io. Thus, the URL to be used to fetch the content is this: https://relay.jare.io/?u=https://www.yegor256.com/index.html (works for me).

Q: APT_BadAlloc from Join Stage in Data Stage There is a ETL job dealing with over 43000000 rows and it often fails because of APT_BadAlloc when it process a JOIN stage. Here is the log.
Join_Stage,0: terminate called after throwing an instance of 'APT_BadAlloc'
Issuing abort after 1 warnings logged.
Join_Stage,3: Caught exception from runLocally(): APT_Operator::UnControlledTermination: From: UnControlledTermination via exception...
Join_Stage,3: Caught exception from runLocally(): APT_Operator::UnControlledTermination: From: UnControlledTermination via exception...

Join_Stage,3: Operator terminated abnormally: runLocally() did not return APT_StatusOk
Join_Stage,0: Internal Error: (shbuf): iomgr/iomgr.C: 2670
My question is about the first warning. The event type is warning and message ID is IIS-DSEE-USBP-00002.
Join_Stage,0: terminate called after throwing an instance of 'APT_BadAlloc'
After this warning, the job has failed and it often occurs. However, I couldn't figure out how to fix it. I only have at least 30 minutes for system resources free and it is effective most of the time.
BTW, it is not a permanent solution, so I'm googling every day but I can't find out what is my first step to resolve the error and how to do it at all.
I saw some options about Buffer size for the system. All the size has the default values. It is very important setting, so I couldn't touch any option here. Please let me know how I can figure out the root cause. I'm not a system admin. I have to contact someone else who can look into a detailed log file about the biggest row in the dataflow.

Q: Sending multiple Google calendar invites using Google apps script Following my previous question, I was able to send a Google calendar invite using the script proposed by @Tanaike:
function testNotification(){
var calendarId = "###";
var eventId = "###";
var email = "###@gmail.com"
addGuestAndSendEmail(calendarId,eventId,email)
}
function addGuestAndSendEmail(calendarId, eventId, newGuest) {
Calendar.Events.patch({ attendees: [{ email: newGuest }] }, calendarId, eventId, { sendUpdates: "all" });
}
However, there is a slight glitch that I am not able to identify. When I try to send invites to multiple email addresses at the same time, it behaves unusually. Here is the new script:
function SendMultiple(calendarId, eventId) {
newGuests = ["[email protected]","[email protected]"];
newGuests.forEach(function(e){
Utilities.sleep(10000);
Calendar.Events.patch({ attendees: [{ email: e.toString()}] }, calendarId, eventId, { sendUpdates: "all" });
});
}
Output:
when the SendMultiple() function finishes running, it sends 2 invites (event created, event canceled) to [email protected] and 2 invites (event created, event canceled) to [email protected], I am unable to identify why the event canceled invite is generated using this script. If I interchange the emails in newGuests array:
newGuests = ["[email protected]","[email protected]"];
then it behaves the same, I would appreciate it if you help me identify the issue, thank you

Q: Breakpoints Don't Hit in Visual Studio Code - What am I Doing Wrong For some reason my VSC breakpoints don't hit. I am not sure why. My launch.json file has
{
"type": "chrome",
"request": "launch",
"name": "Launch Chrome against localhost",
"url": "http://localhost:8080",
"webRoot": "${workspaceFolder}",
"file":"${workspaceFolder}/index.html"
}
I can set breakpoints in my JavaScript code. They show up (correctly) with red dots over on the left. However, they don't hit. Please note that I am only using JavaScript, not TypeScript.
I tried a bunch of changes to my launch.json file and tried moving my JavaScript files around. Nothing worked.

Q: Date input show always format "mm/dd/yyyy" I am creating a react component that allows user to pick a date using a simple "input" field with "date" type. The problem is that I can't manage to display dates in the format "dd/mm/yyyy". it is always displayed as "mm/dd/yyyy".
const [date, setDate] = useState(new Date());
const handleChange = (event) => {
setDate(new Date(event.target.value));
};
const formattedDate = date.toISOString().slice(0, 10);
console.log("Date", formattedDate)
return(
<input type="date" value={formattedDate} onChange={handleChange} />
)
A: The reason why the date is displayed in the "mm/dd/yyyy" format is that the format of the date displayed in an input field of type "date" is determined by the user's browser and operating system settings. Therefore, it may not be possible to guarantee a specific date format across all devices and browsers.
However, you can consider using a third-party library such as moment.js or date-fns to format the date before displaying it in the input field. Here's an example of how you could use date-fns:
import { format } from 'date-fns';
const [date, setDate] = useState(new Date());
const handleChange = (event) => {
setDate(new Date(event.target.value));
};
const formattedDate = format(date, 'dd/MM/yyyy');
return (
<input type="date" value={formattedDate} onChange={handleChange} />
);
In this example, the format function from date-fns is used to format the date variable in the "dd/MM/yyyy" format. You can adjust the format string according to your specific needs.

{url: '/project/1679786259239684'},
{url: '/project/1751999121621250'},
{ url: '/project/2143988207597961'},
{ url: '/project/2141232634002056' }
],
I want to save this array into redis and pop each element one by one.
firstly i try
// save the array
const value = JSON.stringify(array);
this.redisClient
.multi()
.rPush(command:temp, value)
.exec();
// retrieve the array
return await this.redisClient
.multi()
.lPop(command:temp)
.exec();
it doesn't work since I pushed the whole array as as one element.
Then I tried to push each element of the array with redis lPush.
const multi = redisClient.multi();
_.map(messages,function(item){
const value = JSON.stringify(item);
multi.rPush(`command:temp`, value)
});
multi.exec();
however this seems got stuck in the process, how to get it around

Q: Add $ in from of input text in an OutlinedTextField I'm using an OutlinedTextField for the user to input a dollar amount. It works as desired but I would like to add a $ in front of what they are inputting, whether it's one digit or five.
val patternPool: Regex = Regex("^\\d{1,5}\$")
OutlinedTextField(
value = siteValues.valueExtraMoney.value,
onValueChange = { if (it.isEmpty() || it.matches(sitePatterns.patternPool)) siteValues.valueExtraMoney.value = it },
modifier = Modifier
.weight(1f)
.fillMaxHeight(),
textStyle = TextStyle(fontSize = fonts.fontSizeText, textAlign = TextAlign.Center),
label = {
Text(
text ="Extra money taken out of prize pool",
modifier = Modifier.fillMaxWidth(),
fontSize = fonts.fontSizeEntry,
textAlign = TextAlign.Center
)
},
keyboardOptions = KeyboardOptions(keyboardType = KeyboardType.Number),
shape = RectangleShape,
colors = TextFieldDefaults.outlinedTextFieldColors(textColor = Color.Black)
)
I've tried valueExtraMoney.value = "$$it". That outputs a $ plus what ever digit is inputed. But now the string doesn't satisfy the regex and I can't alter the input anymore. I tried playing with the regex to allow a $ but it still gets frozen.

Q: Facial Recognition_1 OpenCV(4.7.0) :-1: error: (-5:Bad argument) in function 'read'
Overload resolution failed:
*
*image is not a numpy array, neither a scalar
*Expected Ptr<cv::UMat> for argument 'image'
I am getting this error from the code and am wondering on how to fix it.
import cv2
import matplotlib.pyplot as plt
cap = cv2.VideoCapture(0)
res, img = cap.read('/Example/photo.jpg')
img = cv2.cvtColor(img, cv2.COLOR_BGRA2RGBA)
fig, ax = plt.subplots(figsize=(10, 10))
ax.axis('off')
plt.imshow(img)
plt.show()
I try to fix the read function but has not worked out for me.
A: cap.read() method doesn't take a filename as an argument. Instead, it reads the frames from the video capture device (camera). So, you need to remove the filename argument and just call cap.read().
You need to check whether cap.read() was successful in reading the frame from the camera. You can do this by checking the value of res. If it's True, then the frame was successfully read, and you can proceed with the rest of the code. If it's False, then you need to handle the error.
Here's the corrected code:
import cv2
import matplotlib.pyplot as plt
cap = cv2.VideoCapture(0)
res, img = cap.read()
if not res:
print("Error reading frame")
else:
img = cv2.cvtColor(img, cv2.COLOR_BGRA2RGBA)
fig, ax = plt.subplots(figsize=(10, 10))
ax.axis('off')
plt.imshow(img)
plt.show()
This code should capture a frame from your camera and display it using matplotlib. If you want to read an image file instead of capturing a frame from the camera, you can replace cap = cv2.VideoCapture(0) with img = cv2.imread('/Example/photo.jpg') and remove the cap.read() line.

Q: The request failed: Google returned a response with code 400 with Pytrends Python Library for Google Trends API I have the following code:
from pytrends.request import TrendReq
keywords = ['example1', 'example2', 'example3']
mapping = {}
pytrends = TrendReq()
for keyword in keywords[:3]:
print(keyword)
pytrends.build_payload(keyword,timeframe='today 12-m')
trend_data = pytrends.interest_over_time()
series = trend_data[keyword[0]]
print(series)
plt.plot(series)
plt.show()
mapping[keyword] = series
time.sleep(65)
For the first keyword in the keywords array, this will work. However, as soon as the for loop iterates to the next keyword, I get "pytrends.exceptions.ResponseError: The request failed: Google returned a response with code 400".
Initially, I thought this was because of rate limits but I set time.sleep() in the for loop to over 1 minute in between requests. Any help would be much appreciated.
A: Maybe this will help. You need to pass a list into build_paylod() per the documentation. I suspect you want to compare the results in one chart, but if not this should at least get you closer:
from pytrends.request import TrendReq
import matplotlib.pyplot as plt
keywords = ['example1', 'example2', 'example3']
pytrends = TrendReq()
pytrends.build_payload(keywords,timeframe='today 12-m')
trend_data = pytrends.interest_over_time()
series = trend_data[keywords]
plt.plot(series)
plt.show()
This will give you a graph like:

Q: How does the altitude of the coffee plantation affect the taste of the coffee? The altitude of the coffee plantation can significantly affect the taste of the coffee due to several factors:
Temperature: Higher altitude coffee farms experience cooler temperatures, which causes the coffee cherry to ripen more slowly, resulting in a more complex flavor profile. Cooler temperatures also allow the coffee to retain more acidity, which contributes to a brighter, more vibrant taste.
Soil: Altitude can also affect the quality of the soil. In high altitude coffee farms, the soil tends to be richer in nutrients, which leads to healthier and more robust coffee plants.
Sunlight: Altitude affects the amount of sunlight the coffee plants receive, which can impact the development of the coffee cherry. Coffee plants grown at higher altitudes receive more direct sunlight, leading to a higher concentration of sugars in the cherry, resulting in a sweeter taste.
Pests and diseases: Higher altitude coffee farms are less susceptible to pests and diseases, as the cooler temperatures and richer soil create a more hostile environment for these organisms. This results in a more natural and pure flavor profile.
Overall, coffee grown at higher altitudes tends to have a more complex and nuanced flavor profile, with brighter acidity and sweeter notes. However, growing coffee at higher altitudes is more challenging and expensive, which contributes to the higher price of specialty coffees that are often grown at these elevations
The thing that i tried was to ask a question in this site and what i expected is to get a result for that question. what actually resulted was i got a better result

Q: Does WireMock support Mocking GraphQL APIs We have multiple micro services which is based on GrapQL and few of them based on REST and each micro service will call multiple other microservices (Java, Spring Boot tech stack).
Now we want to write integration testing for this kind of orchestration.
We thought of using WireMock for Stubbing external Micro Services. But does it support GraphQL? As Wirmock will will support REST MS mocking can it be used for Stubbing GraphQL as well when using with Spring Boot?

Q: i created a library managment system but it would just skip the steps and run all the way down i created a library manangment system with various switch cases and loops and breaks statements however sometimes it works absolutely fie however sometimes it runs the commands and follows all the statement after that particular switch statement
my code is as undergiven
https://onlinegdb.com/aYdKFJSTy
i tired researching on various sites and with my collegues but no one was able to fnd the solution as we all are new to c and are in early learning phase
A: ok so firstly, you should stop posting a complete 900 lines of code and just give a snippet code of the part which you think is giving problem.
Secondly, the places in where you are facing problem, you have missed the break statement at several places in the switch cases. When you do not put break statement in a switch case the case is executed and then all the cases after it are executed sequentially . you can either use break / exit/ continue statements depending upon your requirement.
For example the switch case in the 687th line of your code does not contain any break statement. Hence, all the statements after the case chosen will be executed and an undesirable output will be displayed .

Q: ReactJS Nested List Issue My nested list in ReactJS opens all sublists when I expand
one category
Collapsed List
Expand List
import * as React from 'react';
import ListSubheader from '@mui/material/ListSubheader';
import List from '@mui/material/List';
import ListItemButton from '@mui/material/ListItemButton';
import ListItemText from '@mui/material/ListItemText';
import Collapse from '@mui/material/Collapse';
import ExpandLess from '@mui/icons-material/ExpandLess';
import ExpandMore from '@mui/icons-material/ExpandMore';
export default function SideBar() {
const [open, setOpen] = React.useState(false);
const handleClick = () => {
setOpen(!open);
};
return (
<List
sx={{ width: '100%', maxWidth: 360, bgcolor: 'background.paper' }}
component="nav"
aria-labelledby="nested-list-subheader"
subheader={
<ListSubheader component="div" id="nested-list-subheader">

</ListSubheader>
}
>
<ListItemButton onClick={() => handleClick()}>
<ListItemText primary="Course 1" />
{open ? <ExpandLess /> : <ExpandMore />}
</ListItemButton>
<Collapse in={open} timeout="auto" unmountOnExit>
<List component="div" disablePadding>
<ListItemButton sx={{ pl: 4 }}>
<ListItemText primary="Research Paper" />
</ListItemButton>
</List>
</Collapse>
<ListItemButton>
<ListItemText primary="Course 2" />
{open ? <ExpandLess /> : <ExpandMore />}
</ListItemButton>
<ListItemButton onClick={() => handleClick()}>
<ListItemText primary="Course 3" />
{open ? <ExpandLess /> : <ExpandMore />}
</ListItemButton>
<Collapse in={open} timeout="auto" unmountOnExit>
<List component="div" disablePadding>
<ListItemButton sx={{ pl: 4 }}>
<ListItemText primary="Exams" />
</ListItemButton>
</List>
</Collapse>
</List>
);
}
I found the problem might be that I am using an binary operator to open all the lists. I found this solution ReactJs nested list collapse for only one list item but was unable to implement it properly. Any ideas on what I could do?
A: It is because you are using the same state open for all the items. A simple solution is to have a different state for each one. You could create a different handleClick too or pass the new setStates down into the original handleClick.

Q: Export array of DataFrames to csv I am trying to use tabula-py to extract data from a PDf and save it to a csv. The PDF contains a work order. The data in the PDF is not formatted in a usable table - I am required to use Stream mode.
Through the Tabula web interface, I have created a template and can use it to extract the data to a csv.
My template includes 8 sections.
The csv export from Tabula looks like this: (without a header row though...)
| job number|
| ---- |
| full name |
| phone1 |
| phone2 |
| address-line-1 |
| address-line-2 |
| email |
| jobtype1 |
| jobtype2 |
Using tabula-py, I can run the code df = tabula.read_pdf_with_template("file.pdf","template.tabula-template.json")
The output of print(df) is:
[Empty DataFrame
Columns: [full name]
Index: [], Empty DataFrame
Columns: [phone1]
Index: [], Empty DataFrame
Columns: [phone2]
Index: [], Empty DataFrame
Columns: [email]
Index: [], address-line-1
0 address-line-2
Columns: [jobtype]
Index: [], Empty DataFrame
Columns: [jobtype2]
Index: [], Empty DataFrame
Columns: [jobnumber]
Index: []]
Note: I have changed the output text to the field name
None of the sections that I have selected have a header. Notice the address section shows the address line 1 as the header and address line 2 as the value. This is due to the address being on 2 lines in the PDF.
I have 3 questions:
*
*How do I get the address to be on one line?
*How do I export the output to csv? I know I have to loop through the DataFrame(s) to output one at a time, but python is not my strong suit
*I have over 3000 work orders to process. Is it possible to have the extract appended to the same csv file?
All code used to produce the above results:
import tabula
import pandas as pd
df = tabula.read_pdf_with_template("file.pdf","template.tabula-template.json")
print(df)

Q: How to render a function im passing down as a prop to a child component in React? I'm trying to show a list of times available in a form as options, I was able to so it using useState but now im trying it with a reducer and I can't figure out why its not working. I pass the function down as a prop and then call it int he child component but the options element doesn't render and i'm not recieving any errors in the browser. I can add more information if its needed. I tried to condense it.
//parent component
import BookingForm from '../components/bookingForm'
import { useState,useReducer } from 'react'
function Reservations(){
const initialState = ["17:00","18:00","19:00","20:00","21:00"]
const updateTimes = (availableTimes,action)=>{
return availableTimes
}
const initializeTimes= () =>{
{initialState.map((times) =>{
return(
<option key={initialState}>{times}</option>
)
}
)}
}
const [availableTimes, dispatch] = useReducer(updateTimes, initializeTimes);
return(
<>
<Nav/>
<header>
<div>
<h1>Book a table</h1>
<h2>Little Lemon</h2>
</div>
</header>
<div>
{<BookingForm
initializeTimes={initializeTimes}
/>}
</div>
{<Footer/>}
</>
)
}
export default Reservations
//Child component
import { useState } from "react";
function BookingForm(props){
(...form elements)
return(
<div>
<label htmlFor="res-time">Choose time</label>
<select id="res-time">
{props.initializeTimes()}
</select>
</div>
)
I've pretty much tried doing most things i could think of as I've googled how to pass functions as props to children but have not been successful.
A: change initializeTimes function:
const initializeTimes = () => {
return initialState.map((times) => {
return (
<option key={times}>{times}</option>
);
});

Q: cv2.VideoCapture(0) read frame from a different camera for each run I ran into a very strange problem that appeared out of nowhere, the same code did not cause this problem before.
The following code, the first time I ran it, it read the frame from my connected external camera; the second time I ran it, it read the frame from my MacBook's built-in camera; the third time it read the frame from the external camera.
It just keeps switching and I don't know how to fix it, I want cameraCapture = cv2.VideoCapture(0) to always get the frame from the external camera.
import cv2
cameraCapture = cv2.VideoCapture(1)
# read
success, frame = cameraCapture.read()
while success and cv2.waitKey(1) == -1:
img = frame
cv2.imshow("Mine", img)
success, frame = cameraCapture.read()
Is there any way I can get the data of a certain numbered camera, such as name, resolution, etc.?
A: You can use cameraCapture.get(<property id>) to get different properties of the capture device. There's a full list of them here, but the ones you're looking for are:
*
*cv.CAP_PROP_FRAME_WIDTH for the width
*cv.CAP_PROP_FRAME_HEIGHT for the height.

Q: Round Robin assignment with dynamic assignee group (members can leave the group) I would like to distribute tasks among the active members of a group:
WorkerId
IsActive
001
true
002
true
003
true
004
false
005
false
006
true
Each new task is assigned to the next active member in the group. Tasks are created at irregular intervals, so I need some way of keeping track of the last member to be assigned a task (call him the "last assignee"), so that I can assign the next task to the next active member after him.
Currently, I'm storing the last assignee in a field called lastAssignee. When a new task comes in for assignment, I retrieve the group members from the database and starting from the index of lastAssignee, I loop through the members to find the nearest next active member:
// pseudo-code
let nextAssignee;
let groupMemberIds;
for (let i = 0; i < groupMembers.length(); i++) {
groupMemberIds[i] = groupMembers[i].Id;
}
int indexOfLastAssignee = groupMemberIds.indexOf(RRState.lastAssignee);
for (int i = indexOfLastAssignee; i < groupMembers.size(); i++) {
if (groupMembers[i].IsActive) {
nextAssignee = groupMembers[i].Id;
break;
}
}
RRState.lastAssignee = nextAssignee;
Problem: Members can leave the group.
If lastAssignee leaves the group before the next assignment, then the solution above no longer works, since indexOfLastAssignee will be -1 (since his Id no longer appears in groupMemberIds).
The only solution I could think of was saving a copy of the group members in RRState, so that I can use it on the next assignment:
// pseudo-code
let nextAssignee;
let groupMemberIds;
let oldGroup = RRState.oldGroup;
for (let i = 0; i < oldGroup.length(); i++) {
groupMemberIds[i] = groupMembers[i].Id;
}
int indexOfLastAssignee = groupMemberIds.indexOf(RRState.lastAssignee);
for (int i = indexOfLastAssignee; i < groupMembers.size(); i++) {
if (groupMembers[i].IsActive) {
nextAssignee = groupMembers[i].Id;
break;
}
}
RRState.lastAssignee = nextAssignee;
RRState.oldGroup = newGroupMembers;
But this is clunky and none of the fields of the RRState object support lists. I'm not sure where to go from here, so was wondering if anyone knew of a general round robin implementation that supports dynamic worker groups.

Q: How to install and use PouchDB in react native? I am looking for a simple NoSQL database to be used locally (without sync with server) in a react native app and I decided to give PouchDB a try.
I am wondering which of the following 2 packages I should use :
> npm install pouchdb
> npm install pouchdb-react-native
pouchdb-react-native seems a better choice but its not active, not documented, without tutorials.
Is it possible to install pouchdb-react-native and use the js pouchdb documentation and tutorials?

Q: karate read request as JSON file having tags for data driven scenario I am trying to read the json request from a file, also my request is to get data from .csv file.
however the below code does not replace my keyvalues, and are passed with brackets
expected { "Key1": "HAPPY", "key2": "Val_12", "key3": "Val_13", "key4": "Val_14" }
actual { "Key1": "<key1>", "key2": "<key2>", "key3": "<key3>", "key4": "<key4>" }
Feature: Validate TCs
Background:
Given url 'https://'+env_apiHost
Given path '/abc/pqr-stu/v1/wxy-zzzz'
Scenario Outline: Validate Functional Data
* def request_string = read('classpath:data/jsnStr.json')
And request request_string
When method post
Then status 200
* print response
Examples:
read('classpath:data/jsnVals.csv')|
data/jsnVals.csv
| key1 | key2 | key3 | key4 |
| HAPPY | Val_12 | Val_13 | Val_14 |
| TC_002 | Val_22 | Val_23 | Val_24 |
data/jsnStr.json
{
"Key1": "<key1>",
"key2": "<key2>",
"key3": "<key3>",
"key4": "<key4>"

Q: Averaging temperatures over time on multiple dates I have a device that measures temperature at 10sec intervals and is worn by a subject for a number of days. I want to average the temperatures every 30 seconds. My data set can be missing data points (from an individual 10sec data point missing to a block of several hours if device accidently turned off). The code I have written will average the temperatures over 30 seconds eg 10.30.00 to 10.30.30 but doesn't separate by date so I end up with an average for the one time block over all dates. I have added an example of the data below (same times over 3 days) and the converted table and output. The code I am using is below
data
data as table
output
df_sum <- df[, c('Hour', 'Minute', 'Second') := .(data.table::hour(datetime), minute(datetime),
second (datetime))][, second_Cut := cut(Second, breaks = c(0,30,60), include.lowest = T)
][, .(Avg = mean(CorTemp)), .(Hour, Minute, second_Cut)]
A: library(data.table)
# generate random sample
tmp = seq(as.POSIXct("2023-03-05 12:00:00"),as.POSIXct("2023-03-05 12:12:00"),by="sec")
df = data.table(datetime=tmp,TEMP=37+rnorm(length(tmp),sd = 2))
# this is what you what
res= df[,
.(Hour=hour(datetime),
Minute=minute(datetime),
second_Cut=cut(second(df$datetime),c(0,30,60),include.lowest = T),
TEMP)][,
.(Avg=mean(TEMP)),by=.(Hour,Minute,second_Cut)]
res
This is the input data. BTW, you'd better provide the data file (such as csv file) rather than a screenshot.
This is the output you want.

Q: How can i solve this problem? None of these files exist: * ..\src\components\Main.jsx The full error message is:
None of these files exist:
*
*..\src\components\Main.jsx(.native|.android.ts|.native.ts|.ts|.android.tsx|.native.tsx|.tsx|.android.js|.native.js|.js|.android.jsx|.native.jsx|.jsx|.android.json|.native.json|.json)
*..\src\components\Main.jsx\index(.native|.android.ts|.native.ts|.ts|.android.tsx|.native.tsx|.tsx|.android.js|.native.js|.js|.android.jsx|.native.jsx|.jsx|.android.json|.native.json|.json)
I have the file Main.jsx in ./src/components/Main.jsx but it doesnt detect it
VS Code explorer
The react native version is 0.71.3
The react version is 18.2.0
The node version is 18.14.2
I have tried using backwards slash but htat didnt solve the problem.
App.js
import React from 'react'
import Main from './src/components/Main.jsx'
export default function App() {
return <Main />
}
Main.jsx
import React from 'react'
import { Text, View } from 'react-native'
const Main = () =>{
return (
<View>
<Text>Hola Mundo</Text>
</View>
)
}
export default Main
A: If you are a Mac user try to check file name case sensitivity e.g if your file name is main.js and you are importing Main.js. Then it fails to detect files in mac machines sometime. Moreover try to check if pathname is correct and re-run the server after cleaning npm cache.
For cahce clean you can use command:
> npm cache clean –force

Q: Rails 7.x and Zeitwerk seems to load / find nothing? What did I forget? I have an old Rails 3.x application that I now migrate to 7.x (It is/was already running under 5.0, so it is not so hard).
However, I planed to do this step by step, but it is more or less impossible to install older versions 2023.
The application runs nice and (almost) without any requires with 3.x. Therefore I assume, that I kept the naming conventions.
But zeitwerk ignores all my constants, not complicated things I read in other Q&A, that are tricky. No just easy things.
I bring two examples, that I think zeitwerk should find, but doesn't
I have a config\initializers\site_init.rb that I use to configure some of my modules.
Site.setup do |config|
config.default_do_say=false
config.default_show_all_exceptions=false
end
Site::Cache.setup do |config|
…
end
So I would expect zeitwerk to find it in lib/site/cache.rb
where it is defined like that:
module Site
class Cache
include Singleton
extend Configurable
configurable_local_name 'config', 'setup'
configurable_all_to_module
configurable_global cache_path: "./tmp/cache"
configurable_global auto_file_size: 1000
configurable_global auto_persist: 100
...
The second is also easy (config/initializers/bot_check.rb):
BotCheck.setup do |config|
config.etw_divider=20
config.etw_min_level=0
end
Located in controllers directly
module BotCheck
extend Configurable
configurable_local_name 'config', 'setup'
configurable_all_to_module
# configurable_global start_time: Time.now
configurable_global etw_divider: 5
configurable_global etw_min_level: 0
def self.check_level
count=BotResult.where("created_at > ?", Time.now()-1.hour).count()
Rails.logger.warn "bot check level: #{count}, #{config.etw_min_level}".white.on_red
[count/config.etw_divider, config.etw_min_level].max
end
end
rails zeitwerk:check tells me:
/config/environment.rb:5:in -> NameError: uninitialized constant BotCheck
You see, I struggle early. That's why I am sure, that I have overseen or not understood something very basic of zeitwerk.
The relevant part of application.rb looks like
if Rails.version < "7"
config.autoload_paths += %W(#{config.root}/app/helpers)
config.autoload_paths += %W(#{config.root}/app/helpers/fields)
config.autoload_paths += %W(#{config.root}/app/helpers/tags)

else
config.load_defaults 7.0
config.add_autoload_paths_to_load_path=false
puts "---------------- 7777777 -----------------"
config.eager_load = false
config.autoload_paths << "#{config.root}/lib"
config.autoload_paths << "#{config.root}/lib/site"
puts config.eager_load_namespaces
end
#check for typos
config.autoload_paths.each { |p| puts "autoload_paths: #{p}"; puts "#{p} not found or no directory".yellow if !File.directory?(p) }
config.eager_load_paths.each { |p| puts "eager_load_paths: #{p}"; puts "#{p} not found or no directory".yellow if !File.directory?(p) }

Q: Transactions With MetaMask Returns An Internal JSON RPC Error This is the error MetaMask gives when my app prompts to open it:
{"message": "Error Domain=org.walletconnect Code=-32000 \"Internal JSON-RPC error.\" UserInfo={NSLocalizedDescription=Internal JSON-RPC error.}"}
I tried changing my MetaMask Mumbai Polygon TestNet RPC to the same as the one in my app
(I am using a third party provider called particle.network).
I was looking to get guidance on what might be returning this error message?
