"Help, I keep getting a 'Permission Denied (publickey)' error when I push!"

This means, on your local machine, you haven't made any SSH keys. Not to worry. Here's how to fix:

Open git bash (Use the Windows search. To find it, type "git bash") or the Mac Terminal. Pro Tip: You can use any *nix based command prompt (but not the default Windows Command Prompt!)
Type cd ~/.ssh. This will take you to the root directory for Git (Likely C:\Users\[YOUR-USER-NAME]\.ssh\ on Windows)
Within the .ssh folder, there should be these two files: id_rsa and id_rsa.pub. These are the files that tell your computer how to communicate with GitHub, BitBucket, or any other Git based service. Type ls to see a directory listing. If those two files don't show up, proceed to the next step. NOTE: Your SSH keys must be named id_rsa and id_rsa.pub in order for Git, GitHub, and BitBucket to recognize them by default.
To create the SSH keys, type ssh-keygen -t rsa -C "your_email@example.com". Th

let's say you have a C++ project in Nix that you want to work on with CLion so that the nix dependencies are available.

create a .nix utility directory in your project directory.
put the below nix-run.sh and nix-cmake.sh in the .nix directory.
in the .nix directory create symlinks for make, gcc, g++ - and maybe more tools, that need to have the nix dependencies and build tools available - and point them to nix-run.sh
then, in Settings -> Build, Execution, Deployment -> Toolchains set CMake to the path to nix-cmake.sh and point all other build tools to the symlinks you've created.

How to use clangd C/C++ LSP in any project

tl;dr: If you want to just know the method, skip to How to section

Clangd is a state-of-the-art C/C++ LSP that can be used in every popular text editors like Neovim, Emacs or VS Code. Even CLion uses clangd under the hood. Unfortunately, clangd requires compile_commands.json to work, and the only way to painlessly generate it is to use CMake.

But what if I tell you you can quickly hack your way around that, and generate compile_commands.json for any project, no matter how compilcated? I have used that way at work for years, originaly because I used CLion which supported only CMake projects - but now I use that method succesfully with clangd and Neovim.

Method summary

Basically what we need to achieve is to create a CMake file that will generate a compile_commands.json file with information about:

	<?php
	$server = "localhost";
	$user = "root";
	$password = "";
	$nama_database = "pendaftaran_siswa";

	$db = mysqli_connect($server, $user, $password, $nama_database);

	if( !$db ){
	die("Gagal terhubung dengan database: " . mysqli_connect_error());

	* This resolver forces Jest to look at a custom `"jest"` condition in `package.json#exports`.
	*
	* Whenever you use self-referencing imports or subpath imports in the source code (or tests)
	* the default behaviour of Jest is to go to the package's manifest for information, and resolve
	* the import by choosing one of the conditions that are used by Node ("node", "default", etc.).
	*
	* The issue is that "node"/"default" usually points to transpiled `.js` files, whereas if you decide to
	* run the tests on the `.ts` source code (with the help of a transformer such as ts-jest or @swc/jest),
	* you need Jest to only load the `.ts` files. Otherwise, you end up with duplicated classes,
