OS X Screencast to animated GIF

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.

Screencapture GIF

Instructions

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

Remove metadata from a PDF file, using exiftool and qpdf. Note that embedded objects may still contain metadata.

Anonymising PDFs

PDF metadata

Metadata in PDF files can be stored in at least two places:

  • the Info Dictionary, a limited set of key/value pairs
  • XMP packets, which contain RDF statements expressed as XML

Opening and closing an SSH tunnel in a shell script the smart way

Opening and closing an SSH tunnel in a shell script the smart way

I recently had the following problem:

  • From an unattended shell script (called by Jenkins), run a command-line tool that accesses the MySQL database on another host.
  • That tool doesn't know that the database is on another host, plus the MySQL port on that host is firewalled and not accessible from other machines.

We didn't want to open the MySQL port to the network, but it's possible to SSH from the Jenkins machine to the MySQL machine. So, basically you would do something like

ssh -L 3306:localhost:3306 remotehost

Auto-enable Local HTTP Caching in Test Kitchen

Auto-enable Local HTTP Caching in Test Kitchen

Note: total experiment and hack, looks nasty, could be awesome:

Setup

  • Drop the kitchen.local.yml into $HOME/.kitchen/config.yml
  • Install polipo (with Mac: brew install polipo, with Ubuntu: apt-get install polipo)
  • Drop polipo-start and polipo-console somewhere useful (perhaps $HOME/bin?)

4chan’s guide to converting GIF to WebM - https://boards.4chan.org/g/res/41212767

Grab ffmpeg from https://www.ffmpeg.org/download.html

It's a command line tool which means you will have to type things with your keyboard instead of clicking on buttons.

The most trivial operation would be converting gifs:

ffmpeg -i your_gif.gif -c:v libvpx -crf 12 -b:v 500K output.webm
  • -crf values can go from 4 to 63. Lower values mean better quality.
  • -b:v is the maximum allowed bitrate. Higher means better quality.
