I have a query that joined many table at once, for now it's OK without any performance issue (only less than 100 data in the database). But I'm scared that it will cause some trouble when the data in database become large (ex: thousand of data).
I'm doing join in the same table to get attendance in
Scenario
I've got a one-line user input command that I need to handle and breakdown with regex.
Example:
In 7:00 pm
In MM/DD, This is suppose to check in on a certain day
In 23:11
In -1 Current day minus 1 day
In 7:00 pm -1 Yesterday 7 pm
In @user 7:00 pm -1 generate a time for a @user
Any of t...
I want to make a function to retry calling callback n times until it return TRUE;
Here's my current code:
function RetryX(callback, delay, retries) {
(function wait() {
if( callback() !== true && --retries > 0 ){
setTimeout(wait, delay);
}
}());
}

I want to add a unique ID to every element in a collection (before output it as a JSON object).
A collection can be any set of items, as long as it has a map method implemented (Array, List and other custom collections such as trees comply with this requirement).
(** For a collection 'a t returns...
While migrating to structured concurrency it may be sometimes convenient to temporarily make a blocking call to an async function - e.g.:
let x: Int = try blocking {
try await Task.sleep(nanoseconds: 1)
return 5
}
print(x)
I have this implemented like so at the moment, but I'm not in lo...
After doing about 50 Project Euler problems in my "native" language (C#) I decided to redo some of the problems I did many years ago in F#, as it's a language I always want to give a go. Judging from the code review meta it seems this is okay to post here: Project Euler Solutions
My question is ...
I want to perform some calculations over rolling periods of a pandas DataFrame and to abstract all this in a dedicated class. The job of the class below is simply, given backward and forward looking parameters to slice a column, perform some calculations and append the results as new columns of t...

I've implemented the Nelder-Mean optimization algorithm in C++. I found this document to be a very good explanation of how the algorithm works, but I'll try my best to explain it (with an example) here so it's clear for everyone.
The problem I'm trying to optimize is very simple : I'm trying to f...
Is there a more optimised way?? how to improve this? help out, below are screenshots of the coding problem

Background
Some very good observations were made about my original code in the 2 answers to this question. In the this version I have attempted to reduce cyclic complexity and class coupling even more as well as improve maintainability. The worst offenders of maintainability are now Visual Studio...
Why
hasCustomEntity = true
is never use or call while

has been called?
I question is how to call hasCustomEntity = true
