Clojure Destructuring Tutorial and Cheat Sheet

Simply put, destructuring in Clojure is a way extract values from a datastructure and bind them to symbols, without having to explicitly traverse the datstructure. It allows for elegant and concise Clojure code.

Vectors and Sequences

Compiling plain javascript (no external modules)

So we got nexe to compile nodejs projects to an executable binary:

it downloads the nodejs source
it creates a single file nodejs source (using sardines )
it monkey patches the nodejs code to include this single file in the binary (adding it to the lib/nexe.js)

$ nexe -i myproject.js -o myproject.bin -r 0.10.3

Caveats:

I had an issue with unicode chars that got converted: it uses uglify.js and this needs to be configured to leave them alone

Locate the section for your github remote in the .git/config file. It looks like this:

[remote "origin"]
	fetch = +refs/heads/*:refs/remotes/origin/*
	url = [email protected]:joyent/node.git

Now add the line fetch = +refs/pull/*/head:refs/remotes/origin/pr/* to this section. Obviously, change the github url to match your project's URL. It ends up looking like this:

Most active GitHub users (git.io/top)

The list would not be updated for now. Don't write comments.

The count of contributions (summary of Pull Requests, opened issues and commits) to public repos at GitHub.com from Wed, 21 Sep 2022 till Thu, 21 Sep 2023.

Because of GitHub search limitations, only 1000 first users according to amount of followers are included. If you are not in the list you don't have enough followers. See raw data and source code. Algorithm in pseudocode:

githubUsers

	out/
	src/
	myfiles.md
	static/
	img/
	assets/
	styles.css
	tpl/
	index.jade
	build.js

	<!DOCTYPE html>
	<html>
	<head>
	<meta charset="utf-8">
	<title>Styled Select</title>
	</head>

	<style>

	* {

	#!/bin/bash

	OLDPATH=${PATH}

	UpdateBox()
	{
	echo "-> Installing apt-get packages"
	aptitude update
	aptitude -y install build-essential
	aptitude -y remove libruby1.8 ruby1.8 ruby1.8-dev rubygems1.8

	Useful for when you need to have two hosts talk to each other on a specific port but they're both NATed (behind routers).
	For example, you want to be able to SSH into your friend's machine to pair program with them.

	host-machine$ ssh -R 55555:localhost:22 myaccount@my_ssh_server.com

	connecting-machine$ ssh -L 55555:localhost:55555 myaccount@my_ssh_server.com
	connecting-machine$ ssh -p 55555 user_on_host_machine@localhost

	ffmpeg -i /path/to/a/video -f rawvideo -vcodec rawvideo -s 60x24 -pix_fmt rgb24 - 2>/dev/null \| ./video.js 60 24
