    In an effort to make the web and media more efficient, developers and corporations everywhere are investing effort in creating better file formats and delivery streams.  One of the more impressive video formats I've seen is the WEBM file format.  WEBM files are quite small but the quality is...

    Create Screenshots from Videos

    The idea behind my Get the First Frame of an Animated GIF with ImageMagick post was to improve a page's performance by not loading an animated GIF automatically, but instead grab the first frame, display it, and allow users to "click to activate" the GIF.  That strategy...

    Create Image Thumbnails with ImageMagick

    Oftentimes I'll want to copy the output of a shell command execution but can't get the whole output because it's larger than the terminal's buffer length, so I'll need to write to file for easy viewing, or I'll simply be annoyed that I have to click-hold-drag...

    Every once in a while I accidentally hose my repository's master branch by merging or committing something I shouldn't.  And then on rare occasion I push that to my remote and then things get all sorts of messed up.  Every PR from that point on has...
