cdelsolar··on Born Against, or why hobby programming communities are against LLM usage
Yes, you can see the following:

- https://domino14.github.io/macondo/ - my AI, written in Go. Mostly meant as a "research" tool and doesn't have a proper GUI yet.

- https://github.com/andy-k/wolges - an implementation of a Scrabble AI from scratch in Rust. Andy is very smart and came up with his own algorithm and data structure that we now use throughout our projects

- https://github.com/jvc56/MAGPIE - a friend started this as a rewrite of Macondo, but in C. A lot of new development has gone into this and I've contributed a bit as well. Also no official GUI, but it is _absurdly_ fast, so fast that we can do nested Monte Carlo simulations. Some algorithms have been backported to Macondo with the help of AI.

These are the main 3, but there are people contributing in other ways, someone else has made a CNN and it has good results (I built a CNN as well in the Macondo source, and it has decent results). We're slowly going to continue to improve this until we can use it in real-time for Monte Carlo evaluations, maybe by translating it into a NNUE architecture.

Currently on Macondo I've been working on AI explainability (it's quite good already) and Bayesian inference with a stats PhD candidate. We are likely going to publish a paper on the latter. It's very mathy but it ends up beating the best bot we have so far around 52% of the time (that's actually a pretty significant edge).

You can read about some algorithms on my blog here: https://cesardelsolar.com (very in-depth discussions on inference, CNN, and my exhaustive endgame/pre-endgame algorithm)

cdelsolar··on Protobuf has LSP support
I use Go + Buf + protobuf-es + Connect on my web projects. There is no better stack, I'll die on this hill.
cdelsolar··on Born Against, or why hobby programming communities are against LLM usage
I'm in an _extremely_ niche hobby programming community of Scrabble engine developers. There are single digits of us, but we're building the best engines and methodology out there and have all embraced LLMs to help us do it. There's a lot of experimentation that goes into it and LLMs certainly make it easier to iterate and try new ideas. So at least for our community, I don't think the points here hold.

aw it didn't work with kitty. i get logged out.

timecube?
cdelsolar··on Claude Code uses Bun written in Rust now
The heck? It does all that rendering for a tiny fraction of the total amount of time that the TUI is running. The streaming is IO bound, there’s no way that it’s outputting nearly enough text to tax the CPU that much.
cdelsolar··on Solving 20 Erdős Problems with 20 Codex Accounts Running in Parallel
Have people tried these on Millenium problems.. letting it run all night? You never know.
cdelsolar··on Turn your singing voice into printable notes (in the browser)
i made like infinity of those at scout camp
cdelsolar··on Grok 4.5
fwiw i just asked grok about the 2020 election and it asserted with citations that there is no evidence that it was stolen.
cdelsolar··on Grok 4.5
you think he just "put his arm at that angle" accidentally? like it was a spell?
cdelsolar··on Grok 4.5
i can't tell if this is a joke
cdelsolar··on GLM 5.2 beats Claude in our benchmarks
hmm ok let's build a state of the art from 2021 homelab using 2x Epyc Milan chips + DDR4 RAM and lmk how much it costs...
cdelsolar··on Running local models is good now
What did you call me?

Because he wants to
cdelsolar··on Ask HN: What was your "oh shit" moment with GenAI?
I thought coding agents were probably BS and then I asked Cline to build me a test app to do something (I forgot what, something not that simple) and it built an entire working app. This was before Claude Code which was another step function improvement.
cdelsolar··on Show HN: Eyeball
i got a 0.00% after 3 tries!
cdelsolar··on Why Janet? (2023)
this is incredibly smug, but fun to read :) I briefly "got" Clojure but forgot again. Maybe I'll give this Janet thing a try.
cdelsolar··on The newest Instagram “exploit” is the goofiest I've seen
None of this has to do with AI. Every post here is talking about AI. Did I stumble onto Facebook or something?
cdelsolar··on Anthropic confidentially submits draft S-1 to the SEC
If you believe this is going to happen you can change the allocations of your retirement plans.
cdelsolar··on Bun support is now limited and deprecated
I am not estimating anything. This is my own evidence from my own projects. I have deployed gigantic features this past year, each of which would have taken me the whole year to write.
cdelsolar··on Using AI to write better code more slowly
Tangentially related but I’ve been using Claude to practice interviewing on system design problems, and it’s actually pretty great. But even when it likes my answers it always finds something, however small, to push on. Once it actually was completely wrong and admitted it after I had it realize. So maybe you have to prime it to be contrary and not agree with everything you say, putting it in the role of a tough interviewer seems to do this implicitly.
cdelsolar··on Migrating from Go to Rust
Disagree, if you miss the error handling the code won’t compile (unless you return _, which should be easy to spot)

The magic comment stuff is very much “do it once” and it’s done (for example if using go generate).

cdelsolar··on Bun support is now limited and deprecated
studies suggest nothing. i've released a massive number of features in the last year for several projects that i estimate would have taken me multiple years to put together in a much more mentally exhausting way.
cdelsolar··on Pope Leo XIV’s first encyclical Magnifica humanitas to be published May 25
Amodei seems apropos
cdelsolar··on Local AI needs to be the norm
get the hell out of here with this "TDS" garbage. they literally just disenfranchised all the black voters in the south.
cdelsolar··on Bun's experimental Rust rewrite hits 99.8% test compatibility on Linux x64 glibc
You ask the LLM to explain the code...
cdelsolar··on Bun's experimental Rust rewrite hits 99.8% test compatibility on Linux x64 glibc
why do you think no one understands the code after the LLM rewrites it?
