Another Retro Challenge Has Arrived: CauzCoin!
29 Aug | 16It's been a while since I did a retro challenge since they tend to be quite a bit of work to put together. The last two used modems and my BBS as the heart of the challenge, with the first one simply requiring dialing in with a real modem, and the second one requiring a little more work by decoding a secret message and running some special software. This time around the data won't be encoded as audio, but it will definitely be no less interesting with considerable effort involved. ...

Encoding Software in Barcodes, the Eight-Bit Magazine Way
14 Aug | 16On RetrBattlestations one of the most popular challenges is a recreation of the days when magazines used to publish their own programs.

Again I got distracted with something else and put the project aside for another time. Precariously balancing I didn’t want to have to test the drive by...

Doing Linux Sysadmin Tasks From Your 8-Bitter
17 Jun | 16You decided to "work" from home and you're having a blast killing aliens, rescuing princesses, and finding buried treasure. And of course right while you're in the middle of solving the world's hardest puzzle an urgent call comes in from the office. Of course that means you’re going have to get up and go sit at another computer to ssh in and see what's going on. Wouldn’t it be nice if you didn’t have to do that? Using a combination of tcpser and...
