Drat. The DEC GIGI terminal generates 15 kHz sync, which none of my LCD monitors can do.
Just arrived on my workbench: A DEC GIGI terminal! I never thought I'd own one of these.
Wow, it's been a while. Hi, Fediverse.
The open source and free software movements need more nice, caring, kind people in them.
Actually, I'll amend that. The WORLD needs more nice, caring, kind people in it.
I found an awesome little treasure at Powell's Books today! Dated 1976, a short 64 page booklet.
Everything I know about software engineering I learned after I was 25 years old. Everything I know about electronics I learned after I was 30 years old. I plan to keep learning all kinds of fun shit now that I'm over 46 years old. It's never too late!

As far as I can tell DKIM is just a cryptographically secure way of telling a mail server that you're honestly repesenting yourself as a spammer.
In my ongoing quest to waste time on frivolous projects instead of actually studying Morse code, I have built a visual Farnsworth method CW trainer. I don't do JavaScript much so I had no idea what I was doing. It seems to work anyway! #hamradio https://cwtrainer.loomcom.com/
Oh yeah, I should mention this here! Teensyduino 1.47 ships with a broken Makefile for the Teensy 4.0. It does not work at all. Here's how to fix it.
0. Edit ~/ardunio-1.8.9/hardware/teensy/avr/cores/teensy4/Makefile
1. Change -D__IMXRT1052__ to -D__IMXRT1062__ in DEFS.
2. Change -DF_CPU to 600000000
3. Remove -nostdlib and -nostartfiles from LDFLAGS
Yay, now it works! Use it as the basis for your next fun project.

What do fediverse HAMs think about MBITX? Would it be a good entry into HF QRP SSB world?

(Please boost, if you are followed by a HAM, thanks.)
Well, I am officially giving up on trying to set up a bare metal development environment for the Teensy 4.0, at least for now. I believe it is possible, but I'd rather not fight against the platform too hard. If I gave it some more time, I could probably reasonably set up and use NXP's MCUXpresso, but just using GNU Arm and Makefiles seems extra challenging.
As much as I hate the Arduino IDE, if it works, it works, and it's the path of least resistance.
I'm going to try bit-banging MFM data from a floppy drive with a Teensy 4.0 today!
... man that sounds dirty.

#GMail is harmful to e-mail ecosystem; its antispam blocking policy matches too many valid messages as spam.
It blocked LastPass email leak warning email, because it contained "a link" to a leaked site.
It blocked an e-mail from goverment agency addressed directly to me.
It discriminates all non-gmail servers, and it's pretty much impossible to own a private SMTP server these days, because GMail will classify everything as spam.
It's not how e-mail should work.
Consider dropping GMail.

Gobsmacked at some of the layouts and typography of these TeX and LaTeX projects:

Ads during package installation except its demo scene like "greets" to a selection of other projects used in the creation of that package.
The 3B2/400 I'm currently restoring came from UNIX Systems Labs. Anyone know these two? Their names and phone extensions are on a label adhered to the hard disk bracket.
It's messy, but it works! Finally have a 3B2/400 up and running.
