    Open Files from Command Line on OS X

    I'm as much of a fan of application UIs as anyone else but I'm finding myself working more and more from the command line lately.  Much of that is becoming obsessed with media manipulation but I'm forcing myself to use less UIs so that I...

    Get Stock Quotes From Command Line

    When I conned my way into my first professional programming gig, I didn't really think much about money -- just that I was getting my foot in the door.  But as my career has gone on, I've been more aware of money, investing, and retirement.  I've recently...

    Create an Image Preview from a Video

    Visuals are everything when it comes to media.  When I'm trying to decide whether to watch a video on Netflix, it would be awesome to see a trailer of some kind, but alas that isn't available.  When I'm looking to download a video on my computer...

    Merge GIFs with gifsicle

    Creating a GIF from a video is fairly simple at this point, as I pointed out in Convert Video to GIF or GIF to Video, but working with multiple GIFs is something many people would like to do.  The top GIF manipulation library for years has been

    Convert an Image to Grayscale with ImageMagick

    Get Bitcoin Value with curl or Node.js

    Last year I started dabbling in bitcoin.  Of course I was immediately cocky as bitcoin value went up 20% as soon as I bought it, then was humbled as bitcoin's value tumbled down 50%.  From boathouse to outhouse.  From caviar to ramen noodles.  It was brutal. Anyways, I was...

    Detect if a GIF is Animated

    If you tweet an animated GIF, you'll notice that Twitter takes it and converts it to an mp4.  I'd speculate that they do that conversion because an MP4 is better supported across platforms, at least in that they allow for playing/pause of the animation. And with...

    Convert WAV to MP3 or MP3 to WAV

    Boy I would have loved this post a decade ago when I was ripping CDs from my local library.  The memory is actually quite hilarious:  I would request 100 CDs at a time from the local library system, pick up however had been delivered at 10 a.m. that morning, and...
