The OS I use daily is turning 50, depending on how you define its start. #Unix50

On #Unix's 40th birthday, the IEEE's Spectrum magazine told of its start like this: https://web.archive.org/web/20190228090043/https://spectrum.ieee.org/computing/software/the-strange-birth-and-long-life-of-unix/0

The 50th anniversary of Unix is particularly reminding me of my age because I was born within days of its manual's first edition: https://www.bell-labs.com/usr/dmr/www/1stEdman.html

Thankfully, *that* anniversary is still 2 years off. :p

Huh. Following the boot splash instructions in the #FreeBSD Handbook https://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/boot-splash.html burned me because, for whatever reason, my PC starts up at 1920x1080, not vesa, before the boot menu. I think it kernel-panicked because it kept rebooting.

To boot successfully again, I had to get a loader prompt (option 3) & type:
disable-module vesa
boot

Why does it take me so long to muster the courage to do something as simple as saying hi to someone?

ALL skirts and pants should have usable and useful pockets.

Last night, I stayed up entirely too late writing a howto for something pretty neat: How to add site search to a static website.

I tried to cover a few ways and link to good pages on two I think are neat but can't use.

This therapeutic video is 13 years old now. It's still pretty good at calming me down about modern Mac stuff. https://www.youtube.com/watch?v=GWxC8ezE4Dk

#Unix & #Linux: Can kill just about any kind of process & shuts down when you tell it to.

#Windows: Tasks can stop themselves from being ended, especially tasks not responding. But ending them to shut down? No problem, mate! Shutting dow--UPDATE TIEM!

#MacOS: "Hold my beer." (Gives you a spinning beachball.)

I had a customer in today with Apple Mail problems, & when he went to shut down his Macbook (a newer one, Touchbar & all), Mail stopped it & flat-out refused to quit. My customer spent 5 MINUTES just getting the damn thing to turn off.

There's nothing like debugging why a shellscript launched from cron is running multiple copies, driving the load average ever higher, and causing cron to mail me output adding up to 200 *MEGA*bytes per job run.

And that tripped me up in some subtle ways. I actually needed `ENV=/home/arielmt/.shrc` instead, and to source it on cronjob lines. Now all my jobs are working properly & my crontab looks nice and neat. I updated the page I posted earlier because it was wrong. Double oops.

It turns out I needed `SHELL=/bin/sh` and `ENV=$HOME/.shrc` in my crontab and `PATH=` statements in my .shrc file. Oops.

I just had to figure out why a shellscript working perfectly was refusing to do anything, even quit, as a cronjob. I knew the cron environment was a bit different, but I didn't realize how much, or how to troubleshoot it effectively. Fixed: https://thornton2.com/unix/freebsd/simulate-cron-env.html
