This gist shows how to create a GIF screencast using only free OS X tools: QuickTime, ffmpeg, and gifsicle.
To capture the video (filesize: 19MB), using the free "QuickTime Player" application:
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 = git@github.com: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:
webserver: webserver.c libuv/uv.a http-parser/http_parser.o | |
gcc -I libuv/include \ | |
-lrt -lm -lpthread -o \ | |
webserver webserver.c \ | |
libuv/uv.a http-parser/http_parser.o | |

$(MAKE) -C libuv | |

You should never let passwords or private data be transmitted over an untrusted network (your neighbor’s, the one at Starbucks or the company) anyway, but on a hacker congress like the #30C3, this rule is almost vital.
Hackers get bored easily, and when they’re bored, they’re starting to look for things to play with. And a network with several thousand connected users is certainly an interesting thing to play with. Some of them might start intercepting the data on the network or do other nasty things with the packets that they can get.
If these packets are encrypted, messing with them is much harder (but not impossible! – see the end of this article). So you want your packets to be always encrypted. And the best way to do that is by using a VPN.

This allows you to use the following video streaming services outside of the US from your Mac without having to use a proxy or VPN, so no big bandwidth issues:
# 0. Make sure you have Ruby 1.9.3 installed, and optionally RVM and PostgreSQL | |
# 0.2 If you are on the Mac, make sure you have a c compiler by installing XCode Command Line Tools or gcc4.2 with homebrew | |
# https://github.com/mxcl/homebrew/wiki/Custom-GCC-and-cross-compilers | |
# 0.5 Make sure you have bundler version ~> 1.2 as Rails depends on it | |
gem install bundler | |
# 1. Get edge Rails source (master branch) | |
git clone https://github.com/rails/rails.git |
git-prebase improves on 'git rebase -i' by adding information per commit regarding which files it touched.
Add the executable to your path and git will automatically expose it as
