Fixing Broken Zip Files from Bandcamp - File name too long


Amy Pond, from the TV show Doctor Who, is strapped into a chair. She is saying "OK, kid, This is where where it gets complicated"

I recently downloaded an album from Bandcamp. On trying to extract the zip file using Ubuntu, I got the error "File name too long." This is a known problem with Bandcamp. If you have a problem with long filenames in zip files, here's how to fix it. Quick Solution unzip -p -c whatever.zip "filename.ogg" > […] Read More

Amazon Alexa and Solar Panels


A listing of every possible subject object verb combination

I can now query my solar panels via my Alexa Amazon Dot Echo thingie (why so many names?). I flatter myself as a reasonably competent techie and programmer, but fuck me AWS Lambdas and Alexa skills are a right pile of shite! Sorry if that sounds a bit harsh, but they're a pain in the […] Read More

Converting filenames to Title Case in Linux


A cute penguin - the official mascot of Linux

Here's a simple bash one-liner to convert mixed-case filenames into Title Case: rename 's/(\S+)/\u\L$1/g' * This forces the file extension to lower-case as well. Use rename -n to test the command without changing anything on the filesystem. (Adapted from this PerlMonks FAQ.) Background I have a bunch of inconsistently named files like: HERE COMES THE […] Read More

Scratching my own itch. I have a bunch of directories which I want moved into alphabetic sub-directories. This is handy is you have a bunch of MP3s, books, or other catalogued files.

Add date metadata to MP4 videos

It turns out that you can add similar metadata to MP4 format videos. Here's how to do it with ffmpeg on Ubuntu Linux. The magic option is […] Read More

Replacing IFTTT - Part 1: RSS & Tumblr


I've grown to loath IFTTT. What started out as a cool way to plug internet things together has being an opaque an uncommunicative company with no real interest in customer service. That's not surprising, I suppose, its paying customers are the companies who can't be bothered to develop a proper API and so just shove […] Read More

Converting RAR to ZIP in Linux

As ever, mostly notes to myself. RAR is a silly and proprietary format. I prefer free software and I find that ZIP files are smaller and decompress faster. Not everyone agrees, and that's fine. Assuming you've downloaded a RAR file and want to convert it to ZIP, what's the easiest way? Install P7Zip sudo apt-get […] Read More

Exporting Multitrack Surround Files in Audacity


Notes to myself! Suppose you want to create a surround sound file using Audacity. The app is a little obtuse, so this may clear up some confusion. When exporting, Audacity defaults to mixing down to stereo. You must adjust these settings: Edit → Preferences → Import/Export → Use Custom Mix Lay out your audio. Keep […] Read More
