I was quite fond of mathematical logic and associated fields like model theory and non-standard algebra (hyperreal numbers). Using the hyperreal numbers in math education would actually be pretty cool.

Once I made a small fractal generator with JavaScript to make the fancy images I used in the Fractal Future Forum. But that was actually rather elementary. Huh, maybe I could turn that into an actual app. Migrating it to Rust and Wasm should definitely amp up its performance.

Mostly I focused on geometry at university: Differential geometry, algebraic topology, a little bit of algebraic geometry. In my last job in geoinformatics I actually needed about zero of that, but having had that background was still nice.

Ah, and I considered coming up with a "coviariant" notation for ordinary mathematics. The usual notation is actually "contravariant" in the sense that you need to read f(g(x)) from right to left. A covariant notation would be something like x|g|f (first apply g to x then f).

Actually, I am not doing much with math right now, but focus on getting into the Bitcoin / Lightning / Nostr dev space.

Technically, radivis.com is my homepage, but I haven't posted anything on it since 2015 in favor of focusing on the Fractal Future Forum at forum.fractalfuture.net, which is mostly used as archive now, but it's technically still a working forum. So, yeah, I've gotten rather silent over the last years with only minimal activity on Twitter / X.

What's also relevant is my GitHub at https://github.com/Radivis.

This desolate state of my online presence is bothering me somewhat. I still mostly use Telegram and Discord to stay in touch with people. Migrating everything to Nostr would be cool, but where should I even start?

Anyway, thanks for taking an interest. Is there something you wanted to discuss with me in particular?

I left my comfy full-stack dev fiat job for this: Bitcoin/Lightning/Nostr. Currently learning and working on my portfolio.

True. The Max 20x plan costs just as much as Cursor Ultra. But the latter allows for all models.

Tough call. Probably depends whether I will be more productive with Cursor or OpenCode. Not sure about that. Have to experiment a lot, first.

Am I right that the implication of this is that retards with AIs will win?

I think a hard fork is likely in this situation. The result would be two different blockchains: Bitcoin Data (Bitcoin Core) and Bitcoin Money (Bitcoin Knots). Each of them would have a clearly defined role, keeping both of them relatively "pure". A lot of problems would arise from such a split, but it does make sense.

If we wanted everything to be located on a single blockchain, we would probably all end up on Ethereum PoW or something similar.

I hear you. Cursor has one interesting advantage though: If you get the Ultra subscription, you get twice the amount of credits per $, so you go all out on rapid prototyping with premium models.

So, I see myself ending up using a combination of Cursor and Opencode, depending on what I am trying to build during the respective month. After all, paying for Ultra every month feels wasteful.
