Hi, I'm Charles Childers.

I'm a programmer writing in Forth, assembly, C, and a variety of other languages. I mainly use OpenBSD and FreeBSD.

My best known programs are RetroForth and Konilo. I also write small virtual machines, and a variety of small, personal computing tools. When not programming, I enjoy tea, reading books, riding a bicycle, and cooking.

A bit of #RetroComputing today. Doing some work on my #konilo #forth under an emulated Macintosh running System 7.5.3.

I'm tired of the unending heat and humidity. #SummerWeather

I'm hoping my brother & his family make it through hurricane Beryl without too many problems. (They live in Grenada, which is currently expected to be hit around 7am tomorrow).

I'm tired this morning, so made an espresso. Hopefully the caffeine will help...

@npub1t7d…pqpp Happy Birthday!

Taking a slower day today, I just did a little source cleanup in the command line argument processing code for RetroForth. #DecemberAdventure https://charles.childe.rs/DA2023.txt

@npub1t7d…pqpp Updating is definitely a concern for me. This particular box runs a lot of custom programs (written in a mix of C, old PHP, Python, and Forth). I'll need to rewrite the remaining PHP parts and do extensive testing before I can retire the old system.
It wasn't intended to run this long; the original code was intended as a prototype, but ended up being used and grown in scope over the last decade.

@npub1t7d…pqpp Impressive uptime. It's roughly twice my longest running machine (currently at 1239 days, 2:03). It's an old Ubuntu 14.04 system. This box is long overdue for a rebuild, but I've not had time to do this. (Thankfully it's only accessible to our in-house systems).

Upgrading #FreeBSD is a little more involved than #OpenBSD, but went smoothly.

Just found that my last Linux server was compromised within the last three days. I've shut it down and will rebuild the two sites still hosted on it from clean backups under my #FreeBSD system.

The "TTGO VGA 1.4 Controller" I ordered a couple of weeks back finally arrived. This is a little ESP32 board with PS/2 and VGA ports I saw in a post by @npub1fd3…zn2v. If I'm still able to type by the weekend, I'll be trying to write an ilo vm for it so I can run my konilo #forth.

Playing around with cool-retro-term on #openbsd. It's really slow under a VNC connection, but does remind me a bit of using an actual terminal.

I love these cool, rainy days.

@npub1t7d…pqpp No adaptive charging on the S23 Ultra. I use a routine to limit charging to 85% and standard charging speed during the night. This disables at 4:15 so it's fully charged at 5:00 when I get up.

@npub1t7d…pqpp I think so. I was having some stomach issues yesterday, so this might be related.

Not feeling well today.

I've been working with Arland on revising the graphics vocabulary in Konilo. It's now cleaner and more functional (and no longer requires shape data to be stored packed into structures in memory).
He's now starting to update the existing examples to reflect the changes and I've begun writing documentation for it. For my part, I'll probably give it another hour or two before breaking for the day. I'd like to get some time outside and away from the computer.
