A heck of a lot. Some scripts, other GUI, but out of all the one-offs there are mainly 2 I use every day:
- s3d: fast(ish) image viewer. Basic but it gets the job done.
- Thoth: Text editor with FTP and note-taking features. Even though I uploaded it 2 years ago https://www.mirrorisland.com/thoth but I haven't needed to update anything on it because it does what I need just fine. I also use it to read error logs on various websites via FTP.
I dropped out 2 years ago despite being on there since 2015 which in my opinion was its peak. It was a great place to chat with others about what everyone is building, with their own hands, but now there are too many solutions looking for a problem.
At least hacker news has managed to keep somewhat neutral, despite having its own share of criticisms.
The system usage on this is well-designed. I'm using an ASUS F201E Notebook with Debian 10 and the CPU throttled down to 790Mhz (just a bit less than 0.8GHz) to save battery while I'm out on coding field trips, with CPU usage registering around 20%. Very nice.
After listening to this for an hour, it does well with the minimalist resources it's given. Just like what people do on the Pico-8, limitations start becoming an attractive feature. And you can do a lot with 16 bars. A good example is "Army of Me" by Björk - it only uses 8 bars for its backing track but the constant tweaking of filters make it sound a lot more.
This is starting to get in to www.Pouet.net material. Seriously, you should submit it as a demo. It's not just the coding they're after in demos but also creativity. The votes on HN say it all.
