Disclaimer: I am in no way encouraging or advocating for software piracy. The warez scene in 90s and early 00s was fun to follow. I consider the NFO files a legitimate form of art, not to mention the skills for unpacking and keygen-ing or cracking of the protected software. https://scenelist.org/

growing up in the 80s with a Commodore 64, my friends and I never bought any games. They were all "cracked by $some_cracker"

Me neither, whatever little money we had, it went towards hardware.

I'm in the deep learning music scene, which is due for its stable diffusion moment in the next year or two. The (primarily) timbre transfer system called RAVE is where I'm starting, and my contribution is to optimize the system to improve training time.

This is some really interesting work. Do you happen to have any other good links to see state of the art kind of stuff here? Most of what I happen across seems to be based on MIDI patterns rather than audio.

> The amount of concatenative language interpreters I've abandoned is a bit embarassing. Earlier this week, I watched an excellent talk by Devine Lu Linvega where he was doing a bunch of digging into minimal programming languages. He spent a lot of time looking into Forth and other concatenative languages and he said he found a lot of implementations of the languages, but very little code written in them. It was as i…

I'm convinced that Forth is the inverse of Lisp, and could be equally expressive, but because there are no parens to force matching of parameters, it's way too easy to lose things on the forth stack. I believe that adding types and data structures to Forth, as is done in STOIC, combined with an IDE that allows you to SEE what parameters get eaten where, could make Forth viable for larger programs. I tried to do this…

I'm probably wrong, but my intuition tells me (in terms of Theory of Computation) that Forth is a programming language for Push-Down-Automata, and not a full-blown Turing Machine.

Decreasing network latency by tweaking routers/developing new software: https://www.bufferbloat.net

Do you know that weird phenomenon where you just learned a new word (which is weird in itself, how come I've live 20, 30, 40 year sand never saw this word before?!) and immediately after you see the same word again in an entirely different context? Well that just happened with "bufferbloat". I had just learned about this word on the book "alrogithms to live by". And now, here.

I keep hoping everyone will have that Aha! moment one day, and we'll all have cake. https://libreqos.io

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

Any entry points / tutorials to get started?

- Solopreneur / Indie Hacker / Tiny SaaS scene. This is more an implementation strategy of my dreams of Financial Independence but I find these communities have large overlap. Building small, sustainable solutions to real-world problems to make a decent living. Not glamorous, but lots of freedom. Communities: IndieHackers and lots of people on Twitter.

- Simple Code. I think most system architectures / frameworks / languages are suboptimal - either being hard to reason about or a pain to code in, etc. So this bucket is about trying to find technologies that actually best support their usecases, regardless of what their adoption looks like. This led me to two scenes: Svelte / SvelteKit for frontend and F# for backend / general purpose programming and is now how I build pretty much all my apps (see: https://cloudseed.xyz). The subreddits for both these communities are good.

- Creative Coding / Technology - I used to be more involved here but now am more of an observer. Basically trying to use the power of computing to create cool things - mostly artistic. This comes in a range of forms but typically procedural / generative art is at the core. Subreddits r/generative and r/creativecoding are pretty active

Ooooooo, any good links to share? I picked up a Draftmaster II at auction and someday I'll get it working I promise...

I'd also love to know this. I had a fascination with the (to me) gigantic plotter at my Dad's workplace (they did a lot of architectural and engineering drawings on it). I had completely forgotten about this until these comments came along, and now I'm trying to work out where I can put one at home :)

As for hardware, consider picking up a cheap vinyl cutter. Most of them are knockoffs of the Roland CAMM series, which itself is a beefed-up knockoff of the early HP pen plotters. As a result, they all speak HPGL, and most of the blade holders are basically modified pen holders. You can put a pen in a vinyl cutter, and most of them include a pen holder by default, as a way of testing the machine without wasting vinyl.

Vinyl cutters are optimized for slower motion with more stiffness and torque, whereas pen plotters expect nearly zero force on the tip and are optimized for speed and acceleration, but if you're not running production, speed won't matter so much. Vinyl cutters also have controllable downforce (by regulating the current in a solenoid), which can be neat.

My local makerspace has a USCutter MH-series, which is available in a cute little desktop size, or with a sensible stand for the larger models. Contrast with most of the genuine-vintage plotters that are weirdly bulky and awkward, not built to come apart for transport, and have 40-year-old power supplies lurking inside just waiting to blow up.

I've been following closely emulation scene since 1999, more recently, I started following FPGA recreation scene. Never imagined what emulation would turn nowadays, specially since it's officially supported and sold by companies which back in the day they saw it as an evil practice.

Algorithmic art and pen plotters - super fun and wonderful community.

Ooooooo, any good links to share? I picked up a Draftmaster II at auction and someday I'll get it working I promise...

I like the drawingbots discord server, and this blog: https://inconvergent.net/#about, also follow #plottertwitter

- Systems that work offline. Partly for practical reasons due to my background working in Agtech companies, as well as logistics in developing countries. But also it's just technically and socially fascinating. How do you detect conflicts? How do you decide what one is? To what extent - if any - can it be resolved automatically? Revisions, event sourcing, CRDTs... there's no one size fits all industry solution and no…

I love offline systems. IoT is everywhere, garage doors should not need the internet. SyncThing is one of my biggest inspirations in software. They are one of the only projects I consider truly getting P2P right, ever, and there's a nice ecosystem of stuff people have been doing with just that one primitive of a folder that syncs. A lot of the time it seems like you really don't need advanced conflict resolution, if…

> there's a nice ecosystem of stuff people have been doing with just that one primitive of a folder that syncs.

Ooooo, got links?

Out of curiosity, how heavyweight is Syncthing, computationally? Could it run in an ESP32? I've used that same "folder that syncs" concept in some of my own designs which I would love to push down to smaller hardware...
