Business models based on the compiled list at http://news.ycombinator.com/item?id=4924647. I find the link very hard to browse, so I made a simple version in Markdown instead.

FizzBuzz solved using only bit twiddling. It essentially uses two deterministic finite automata for divisibility testing.
#include <stdio.h>
int f0(unsigned int x) { return x? (x&(1<<31)? f1(x<<1) : f0(x<<1)) : 1; }
int f1(unsigned int x) { return x? (x&(1<<31)? f3(x<<1) : f2(x<<1)) : 0; }
int f2(unsigned int x) { return x? (x&(1<<31)? f0(x<<1) : f4(x<<1)) : 0; }
int f3(unsigned int x) { return x? (x&(1<<31)? f2(x<<1) : f1(x<<1)) : 0; }
int f4(unsigned int x) { return x? (x&(1<<31)? f4(x<<1) : f3(x<<1)) : 0; }
int t0(unsigned int x) { return x? (x&(1<<31)? t1(x<<1) : t0(x<<1)) : 1; }
int t1(unsigned int x) { return x? (x&(1<<31)? t0(x<<1) : t2(x<<1)) : 0; }
int t2(unsigned int x) { return x? (x&(1<<31)? t2(x<<1) : t1(x<<1)) : 0; }

A simple, made-up example of the code for a simple AngularJS blog viewer as a more detailed exploration of http://benhollis.net/blog/2014/01/17/cleanly-declaring-angularjs-services-with-coffeescript/ . Yes, I know about `$resource`, but I prefer not to use it.
app = angular.module 'BlogExample', []
# Simple controller that loads all blog posts
app.controller 'BlogCtrl', ['$scope', 'Blog', ($scope, Blog) ->
# Get all the blog posts
Blog.all().then (posts) ->
$scope.posts = posts
# Extend the $scope with our own properties, all in one big block
# I like this because it looks like declaring a class.

has class function - vanilla JS. Check if element has specified class
// hasClass, takes two params: element and classname
function hasClass(el, cls) {
return el.className && new RegExp("(\\s|^)" + cls + "(\\s|$)").test(el.className);

/* use like below */
// Check if an element has class "foo"
if (hasClass(element, "foo")) {

lonetwin / Git dot files management
Last active April 29, 2025 08:27
A simple way to manage dotfiles with git without silly symlinks and special tools. Just use negative matches in your .gitignore !
I like to manage dotfiles without having to mess with silly symlinks or having
to install/configure specific dotfile managament tools. So here's what I did:
$ cd ~
$ git init .
$ echo '*' > .gitignore # ignore all files by default
$ echo '!.bashrc' >> .gitignore # ...and then tell git what files not to *not* ignore
$ # ...add other files you may want to track to *not* ignore
$ git add .bashrc # now actually add the files to git
$ git add .gitignore # add the .gitignore to git

Conditionally switch between source maps and minification based on a gulp flag.
// `gulp stylus --prod` will enable "production mode"
// `gulp stylus` will leave the prod flag undefined, so it will do a dev build
var gulp = require('gulp'),
gutil = require('gulp-util'),
prod = gulp.env.prod;
gulp.task('stylus', ['cleancss'], function () {
var stylus = require('gulp-stylus'),
prefix = require('gulp-autoprefixer'),
minify = require('gulp-minify-css');
