OS X Screencast to animated GIF

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

Instructions

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

devoncrouse

# Create background noise profile from mp3
/usr/bin/sox noise.mp3 -n noiseprof noise.prof

# Remove noise from mp3 using profile
/usr/bin/sox input.mp3 output.mp3 noisered noise.prof 0.21

# Remove silence from mp3
/usr/bin/sox input.mp3 output.mp3 silence -l 1 0.3 5% -1 2.0 5%

# Remove noise and silence in a single command

Install psql on WSL

Home

This install is pretty different from previous versions of psql install instructions for windows. This install uses the WSL and Ubuntu shell.

We are installing this through the Ubuntu command line which is different from the other Ubuntu install instructions because those instructions use Ubuntu's GUI, which we don't have access to here.

NOTE: Since this is a service that is running on Ubuntu, you should be in the the Ubuntu file system when running these commands!

Caveats

• NOTE: I had to reboot after doing this to eliminate display artifacts.
• Also, the dock doesn't appear to support using both of the displayport ports simultaneously :'(
• And MST (https://en.wikipedia.org/wiki/DisplayPort#Multi-Stream_Transport_(MST) ) doesn't seem to work on this dock, so you can't daisy chain monitors.

TLDR

1. download driver from http://www.displaylink.com/downloads/ubuntu
2. unpack
