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:

for i, filename in enumerate(sorted(os.listdir("."))):
  os.rename(filename, "{0}.png".format(i))

minitech’s Web Checklist

Here are some guidelines that will make me actually like your amazing new web application!

1. Make sure encoding is handled properly every step of the way. If ’ comes out as ’, you’ve got a problem on your hands. 😊

2. Make it accessible. Turn off images, JavaScript, and CSS. If your website is still legible and usable (it’s okay if it’s just barely usable, or not particularly interactive) then you are already in the top 0.01%.

3. Check your grammar. One of the fastest ways to lose respect in a blog post (or worse — in body copy) is to make basic orthographical or grammatical mistakes. These include, but are not limited to:

• Missing apostrophes — [Bitbucket even did that][bitbucket-apostrophe-catastrophe].

Overview

The Freeseer project is a powerful software suite for capturing video. It enables you to capture great presentations, demos, training material, and other videos. It handles desktop screen-casting with ease. It is one of a few such tools that can also record vga output. It is particularly good at handling large conferences with hundreds of talks. Freeseer can run on a laptop with commodity hardware such as a web cam, camcorder, or vga capture device. The resulting system fits easily into a laptop and can be assembled in under 10 minutes to record any number of presentations/demos/talks.

Freeseer is implemented in Python, uses Qt for its GUI, and quite approachable and easy to learn the code base given it's clear structure and reasonable size (17K lines of code). One can make a significant contribution to Freeseer, perhaps more than many other open source projects.

Freeseer is the best software available for recording large conferences. We have put a lot of thought and automation into work flow to
