Taking a Better Photo of a CRT Screen with a Phone

As a frequent reader of the retrobattlestations and VintageApple subreddits, I see a lot of photos of CRT screens that show significant scanlines resulting in images like the one on the left.

Writing and Running a BBS on a Macintosh Plus

In 2015, I wrote a custom BBS server in Ruby and had been using it to run my Kludge BBS on a small OpenBSD server in my home office since then.

Last year after writing a lot of C on my Macintosh Plus, I had the itch to write a new BBS server so I could move my BBS to run on another Mac Plus. As with all software development projects, it took quite a bit longer than expected, but last month I finally got far enough with the development to deploy the new BBS on a Mac Plus.

Live Streaming a Macintosh Plus (or Any Compact Mac)

Since recording a handful of C Programming on System 6 videos, I've occasionally wanted to live-stream the more casual daily programming being done on my Macintosh Plus. After getting all of the pieces together, I now have a working self-hosted broadcasting setup.

If I happen to be programming on my Mac right now, you can watch here at my website.
