They say you should be the change you want to see in the world. That's why I'm backing the Reform open and repairable laptop, and why I think you should too! https://www.crowdsupply.com/mnt/reform

I think perhaps the biggest mistake made when creating the current fediverse was making instances culturally significant (i.e., making instances islands of users with a shared interest). It has led to the current arms race between instances blocking and canceling each other.

In my (correct) opinion, an instance of a distributed peer-to-peer messaging system should be nothing more than a dumb node that serves as a message source and sink.

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.

IRC is still pretty great.

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!

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.

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.

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.
