Description

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"

YouTube 1080p Downloader

The Problem

It used to be you could directly download any YouTube video in any quality you wanted, as a single .mp4 file. However, around a year ago, YouTube switched from the "single file stream", to "DASH" streaming, which streams the video and the audio to you as two separate streams, which are played in sync with each other in the YouTube player.

It's still possible to download YouTube videos as a single file, but YouTube only offers that for qualities up to 720p. So you can't download "single file stream" videos in 1080p or higher.

git-snapshot

Out of band syncing to a local git branch.

This started as an experiment to see how commits could be created without modifying the working directory, the index, or the state of HEAD. The end result is like a cross between rsync and git stash using a specified branch.

	Acme Envy
	I love having the latest versions of Perl, Python, and Ruby at my disposal. For some time now I've been managing my Perl installations with perlbrew, my Python installations with pythonbrew, and my Ruby installations with rvm. They all work fine and I continue to manage my desktop machine this way.

	But a while back, I tried rbenv on my laptop. It worked great! Just clone the repositories

	$ git clone git://github.com/sstephenson/rbenv.git .rbenv
	$ git clone git://github.com/sstephenson/ruby-build.git \
	~/.rbenv/plugins/ruby-build
	initialize in your shell

	pip search . \| egrep -B1 'INSTALLED\|LATEST'
