while

double-clicking a .repo file when Amend is already running (thanks to Steve

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.
With a simple post-processing tip on the iPhone (though there is probably a
similar technique for Android phones), it's easy to fix this photo after it's
been taken so it looks like the one on the right:

This is the initial public release of the Subtext BBS server for Classic Mac OS.
It represents a
full year
of development and testing while operating the
Kludge BBS
on my Macintosh Plus.
Thanks to all past and present Kludge users for feedback and bug testing.
I recently acquired a 3M Whisper Writer 1000 communications terminal circa 1983,
and restored it to working order.
This is a short session of it dialing into my
Kludge BBS
(hosted on a Macintosh Plus circa 1986)
over its internal 300 bps modem.

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.

Introducing my
Wallops
IRC client, then returning to work on the BBS adding a serial module to join the
console and telnet inputs to allow calls through a modem.
I got stuck for a while trying to figure out why writes to the serial port would
hang the machine.

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.

I was trying to use a V4L2
Ruby module
on my OpenBSD laptop but ran into a problem where sending the V4L2 ioctl
s from
this module would fail, while other V4L2 programs on OpenBSD worked fine.
Since I got a few
questions
recently about kernel development and debugging, I thought I'd write up how I
finally tracked it down and fixed it.
(Spoiler: it was not an OpenBSD problem.)
