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"

Some notes on why Go works for me and why it might work for you if you're looking for another language to add to your repetoire. Goes without saying that this reflects my personal taste.

Go features that I particularly like

Multicore is the future so I like that Go has concurrency built right into the core. Goroutines and channels provide a very accessible metaphor for thinking about concurrent programming. They're supported by language features that really make Go shine in this area. The select statement, for example, makes it easy to listen to and synchronise events from different concurrent threads.
Provides both pointers and value types, but the pointers are safe and managed. Automatic memory management means its safe to return a pointer to a local variable.
Interfaces in Go are smooth and unobtrusive. They automatically apply to anything with the right function signature so you can define interfaces that are satisfied by 3rd party code without you having to change it.
Errors are signale

a simple git branching model (written in 2013)

This is a very simple git workflow. It (and variants) is in use by many people. I settled on it after using it very effectively at Athena. GitHub does something similar; Zach Holman mentioned it in this talk.

Update: Woah, thanks for all the attention. Didn't expect this simple rant to get popular.

Order of evaluation in PHP

Yesterday I found some people on my [favorite reddit][lolphp] wonder about the output of the following code:

<?php

$a = 1;
$c = $a + $a++;

This is not intended to be comprehensive or authoritative, just free online resources I've found valuable while learning more about Erlang.
