Normalize volume level with PulseAudio and simultaneous output

This should work conceptually on any Linux OS with PulseAudio but these particular instructions are for Ubuntu. There are two major reasons for using simultaneous output. The first is self-evident - we can output to say a bluetooth headset and wired headphones at the same time to enable two people to watch a movie with headphones on a single computer. The second reason is a sort of a convenience for setup. We know the simultaneous sink name so the default.pa config would work without modification so long as simultaneous output is enabled. If we were to set this up without that, we'd have to customize the config with our specific device sink name. That's totally doable but personally I always setup simultaneous output. That's why I haven't described the alternative in this gist.

OS X Screencast to animated GIF

This gist shows how to create a GIF screencast using only free OS X tools: QuickTime and ffmpeg.

Forked from https://gist.github.com/dergachev/4627207. Updated to use a palette to improve quality and skip gifsicle.

Instructions

To capture the video (filesize: 19MB), using the free "QuickTime Player" application:

# most people include something like this. don't.
# check your default nginx.conf, it's already covered in a much better way.
#gzip_disable "MSIE [1-6]\.(?!.*SV1)";

# compress proxied requests too.
# it doesn't actually matter if the request is proxied, we still want it compressed.
gzip_proxied any;

# a pretty comprehensive list of content mime types that we want to compress
# there's a lot of repetition here because different applications might use different

To remove a submodule you need to:

• Delete the relevant section from the .gitmodules file.
• Stage the .gitmodules changes git add .gitmodules
• Delete the relevant section from .git/config.
• Run git rm --cached path_to_submodule (no trailing slash).
• Run rm -rf .git/modules/path_to_submodule (no trailing slash).
• Commit git commit -m "Removed submodule "
• Delete the now untracked submodule files rm -rf path_to_submodule
