Gerät 32620: the machine that powered numerous number stations
A few years ago, I first stumbled over some recordings of number stations and started reading up on their history. For most of them, we have pretty good guesses who ran them and for what purpose. One example is the Gongs and Chimes Station , known for its melody that got increasingly creepy over the years, the more…

I couldn't wait for the new Mac Pro
For those of you coming from Hacker News wondering why I need OS X it’s because I’m an indie developer that makes this. I’m not sure if it was the after the 4th or 5th time my Macbook Air hard crashed rendering in Final Cut Pro that my planned upgrade timing would need to be brought forward. In any case, the writing…
