I sometimes write COBOL programs for fun. Seriously... one of the things COBOL used to require and still strongly encourages is to declare record types before procedures (the Data Division is before the Procedure Division). There's a Fred Brooks quote that goes: "Show me your flowcharts and conceal your tables, and I shall continue to be mystified. Show me your tables, and I won't usually need your flowcharts; they'l…

Sounds like functional domain driven design

Digital Artificial Life -- as in evolving program ecosystems, artificial chemistries or cellular automata that can manifest life-like phenomena, etc.

Haven't done much with it in a while but was very into it in college. It's both a minor scientific field (would probably be grouped under both theoretical biology and AI research) and a hobbyist field with some really interesting projects.

Earlier quoted context omitted.

Are there any particular communities or groups for this you can recommend? Here are a few I've discovered that I've really been enjoying lately: https://tildeverse.org (EDIT: apparently they don't like being linked to from HN; copy and paste the link instead of clicking it) https://indieweb.org https://neocities.org I think the main focus of those communities is recapturing the spirit of the (arguably more fun) inter…

That tildeverse URL is not going where you think it is...(Currently set to Rickroll.)

Ah, I forgot, it specifically does that when referred from HN.

Locksport and tying knots are two skills I would love to develop but I don't get enough opportunity to use them to use the application of the skill as the driver. Probably need to find a community for each to see if that helps.

Climbing is a great way to learn knots in an applied way.

oh wow, I have no idea why I didn't think of that. thank you!

I am still phreaking and active in the demoscene.

what really exists in phreaking? I used to be interested in the mid-late 90s, but it seems it was all but dead by 2000 or so. Asterix seemed to keep things interesting for a bit, but I haven't heard about that in years.

In the last years it shifted mostly to tinkering with radio communication of all sorts. IoT etc. it's amazing what you can find out about factories and your general environment if you have a look at everything that's buzzing around... with mostly default passwords. :) but there are still interesting systems around just last week I found a 170 line isdn system still in use by a printing company... roughly 1mbit :D

I have been working on PlayStation 1 homebrew SDKs [1] and tools over the last year. Unlike other retro consoles - especially Nintendo consoles - the PS1 gets almost no attention at all; "PS1-style" games made using Unity or Unreal Engine seem to be decently popular, but nobody wants to bother with the real hardware anymore. Which is a shame, as the PS1 is a relatively simple platform which can be found for relativel…

Can I run programs built in this SDK on an original PS1? Like the one I have from when I was a kid? I'm interested, I'm gonna check it out.

Most of the SDK has been tested and confirmed to be fully functional on real hardware, but there is some copy protection you will have to get around in order to run arbitrary software on a PS1. The traditional solution is to perform disc swapping or install a modchip, but nowadays we also have softmods [1] that make the process as easy as inserting a specially formatted memory card (which can be prepared using a PS2, or even a PS1 by swapping discs).

You are not required to use CDs either. With the help of some code and linker script magic, you can build an image that can be booted directly from a cheat cartridge (or simply a parallel EEPROM) connected to the console's expansion bus, bypassing the copy protection checks entirely. There are also debugging tools that, once loaded, let you download an executable into RAM for quick testing and manage memory cards using a modified serial cable [2].

NFT generative art "scene" on fxhash [0]. There's some great art, articles and people there and on twitter [1]. There are problems, as with any community, but, in my opinion, "web3" at it's finest.

I don’t know that I’d describe it as “weird”, but for me it’s sequenced Christmas Lights. My setup is relatively small, but yes, I’m that guy with the big Christmas light display. This year I’m at about 1500 RGB LEDs this year (again, still pretty small) it’s fun hobby. The weirdest part for me still is custom ordering hundreds of dollars of lights from Chinese companies directly.

HEY. I'm looking for dependable, C9 lights. Would you know where to look? I love the look of the old-timey large bulbs, but so far the lights I've found have been; a) overly expensive and b) not able to withstand more than one winter in the upper-Midwest.

Any recommendations?

Atari 2600 programming. I haven't made anything useful myself yet, but I've been following the community very closely for a few years. There's tons of great new games being made all the time.
