joiner | simple utility for SQL-like joins | CSV Processing library

I was working on one telegram bot, and when finally I made everything I discovered that it is extremely slow.

s() takes 5-7 seconds to get result and send it to user, I tried to optimize it with methods from other sites, but it didn't work.

How can I optimize it?

I am currently coding a function that would allow a user to start a game from a lobby (a bit like the game among us : the owner click start the game and the game starts.)

To do so, i first get my lobby id (=token) with the path and then check if this lobby exists and if everyone in the lobby is ready. If this two conditions are validate, I return just a ok code (200).

If i try my request with insomnia request it work well. The issue i have is that i wuld like to create the Unit test function that test this function startGame.

This is my function code :

following are my files for html, .ts and json . As json data was very extensive therefore i have just added a few states and their cities. my 1st dropdown is showing all states. Now I want to match my 1st dropdown's selected value of state with a key "state" in "cities" object in my json file so i can populate 2nd dropdown with cities relevant to that state. and I want to do this in function "getCitiesForSelectedState". please help me find solution for this.

I'm using SymPy, a Python library for symbolic mathematics, to reduce inequalities which are programmatically read in, for example

I'm new to the "async/await" aspect of JS and I'm trying to learn how it works.

The error I'm getting is Line 10 of the following code. I have created a firestore database and am trying to listen for and get a certain document from the Collection 'rooms'. I am trying to get the data from the doc 'joiner' and use that data to update the innerHTML of other elements.

I have checked that $clause is a hash reference and also that it has two keys children and joiner by iterating keys %{$clause}

To see what value children key holds, I printed them.

To fit a SQL template in a Java app, I need to format elements as follows:

I have a Galera cluster running on MariaDB containers, and only the bootstrapping node accepts connections - the other ones don't create a socket.

I'm baffled by this behavior since all the nodes are created from the same VM template and have the same configuration (apart from wsrep_cluster_address = gcomm:// in the bootstrapper node).

I'm using mariadb/server:10.4 as the container image.

/etc/mysql/my.cnf (the only configuration file that exists and is the same across all nodes):

I am attempting to put together some example code from a book.. but the book and the github copy are different.. I think I am close to having a working example of a threadpool which accepts functions and wraps them so you wait for their value to return as a future... but getting compilation errors around templating

I've tried to instantiate the exact class I need at the end of the helloworld.cpp like told in

Why can templates only be implemented in the header file?

but then proceed to get a bunch of warnings about trying to imply a function which I had set as =delete already...

see what I mean under Why do C++11-deleted functions participate in overload resolution?

I'm a bit new to C++ still so unsure how to best proceed , compilation error is at the end.. I have already tested thread_safe_queue.cpp and it worked in other simpler usages already so I don't believe it's at fault here... more so the templating is needing help
