Windows 10 version 2004 - Installing Node.js on Windows Subsystem for Linux (WSL/WSL2)

UPDATE (Fall 2020): This gist is an updated version to the Windows 10 Fall Creators Update - Installing Node.js on Windows Subsystem for Linux (WSL) guide, I usually just keep here notes, configuration or short guides for personal use, it was nice to know it also helps other ppl, I hope this one too.

Windows updated windows subsystem for linux to version 2, as the F.A.Q stated you can still use WSL version 1 side by side with version 2. I'm not sure about existing WSL machines surviving the upgrade process, but as always backup and 🤞. NOTE: WSL version 1 is not replace/deprecated, and there ar

Methods of Signing Git Commits on MacOS

Last updated March 13, 2024

This Gist explains how to sign commits using gpg in a step-by-step fashion. Previously, krypt.co was heavily mentioned, but I've only recently learned they were acquired by Akamai and no longer update their previous free products. Those mentions have been removed.

Additionally, 1Password now supports signing Git commits with SSH keys and makes it pretty easy-plus you can easily configure Git Tower to use it for both signing and ssh.

For using a GUI-based GIT tool such as Tower or Github Desktop, follow the steps here for signing your commits with GPG.

First Method

Deleting the .git folder may cause problems in our git repository. If we want to delete all of our commits history, but keep the code in its current state, try this:

# Check out to a temporary branch:
git checkout --orphan TEMP_BRANCH

# Add all the files:
git add -A

	// 1. Even or odd

	function isEven(value){
	if (value % 2 == 0){
	return true;
	}
	else
	return false;
	}

	What is OSI model?
	The OSI model (Open System Interconnection) model defines a computer networking framework to implement protocols in seven layers. A protocol in the networking terms is a kind of negotiation and rule in between two networking entities.

	Layers of OSI model:
	Physical layer

	The Physical layer is also called as the Layer 1. Here are the basic functionalities of the Physical layer:

	Responsible for electrical signals, light signal, radio signals etc.
	Hardware layer of the OSI layer

	-- Get Max ID from table
	SELECT MAX(id) FROM table;

	-- Get Next ID from table
	SELECT nextval('table_id_seq');

	-- Set Next ID Value to MAX ID
	SELECT setval('table_id_seq', (SELECT MAX(id) FROM table));

	# Couldn't figure out how to do /s or get VS Code to search over newlines so came up with this convoluted mess '[\S\s]*?\n?' that matches all characters plus newlines

	Search for: <(table\|tr\|td\|p\|div\|span)[\S\s]*?\n?>
	Replace with: <$1>
