This simple script will take a picture of a whiteboard and use parts of the ImageMagick library with sane defaults to clean it up tremendously.
The script is here:
#!/bin/bash
convert "$1" -morphology Convolve DoG:15,100,0 -negate -normalize -blur 0x1 -channel RBG -level 60%,91%,0.1 "$2"
When the directory structure of your Node.js application (not library!) has some depth, you end up with a lot of annoying relative paths in your require calls like:
const Article = require('../../../../app/models/article');Those suck for maintenance and they're ugly.

In August 2007 a hacker found a way to expose the PHP source code on facebook.com. He retrieved two files and then emailed them to me, and I wrote about the issue:
http://techcrunch.com/2007/08/11/facebook-source-code-leaked/
It became a big deal:
http://www.techmeme.com/070812/p1#a070812p1
The two files are index.php (the homepage) and search.php (the search page)
| function get_avatar_from_service(service, userid, size) { | |
| // this return the url that redirects to the according user image/avatar/profile picture | |
| // implemented services: google profiles, facebook, gravatar, twitter, tumblr, default fallback | |
| // for google use get_avatar_from_service('google', profile-name or user-id , size-in-px ) | |
| // for facebook use get_avatar_from_service('facebook', vanity url or user-id , size-in-px or size-as-word ) | |
| // for gravatar use get_avatar_from_service('gravatar', md5 hash email@adress, size-in-px ) | |
| // for twitter use get_avatar_from_service('twitter', username, size-in-px or size-as-word ) | |
| // for tumblr use get_avatar_from_service('tumblr', blog-url, size-in-px ) | |
| // everything else will go to the fallback | |
| // google and gravatar scale the avatar to any site, others will guided to the next best version |
