cdelsolar··on Apple introduces the new 14-inch MacBook Pro with M6
Yeah I use KDE as well for my desktop and it’s the perfect environment. (Btw I use Arch)

Still I’m very tempted by the new MacBooks. I don’t know of any laptop that is a tenth as good and I don’t want to sit at my desk all day to use a computer.

cdelsolar··on eMudhra to exit global SSL/TLS certificate business
i think this oversells the likelihood of it. the probability of any random 116 digit number having its first 115 digits be the number zero is much lower than that of it containing a much higher number of non-zero digits.

cdelsolar··on Ask HN: How to deal with shipping AI-written code you don't understand?
right? I love HN. This is the new hot take, spoken as confidently as possible -- NO TESTS AT ALL.
cdelsolar··on Ask HN: How to deal with shipping AI-written code you don't understand?
no you're not lol. You're managing a team of ever improving engineers. Opus 5.5 is almost paranoid about testing literally all its assumptions. It's already a better coder than me and I've been doing this for 30 years.

cdelsolar··on Worlds more habitable than Earth?
It wouldn’t be that fun to live on one. The article says picture paradise, but we’re talking about potentially 1.5-2g with a dense atmosphere; we’d feel terrible all the time. Also whatever biology is in that planet is probably not compatible with us; we likely wouldn’t be able to eat it. Finally once you land, you’re screwed and stuck there. Traditional chemical propellants barely work for our planet, we’d need new ways of taking off for higher escape velocities.

Can you really mine water in interstellar space, how? there’s not that many asteroids just floating out there, I think.

cdelsolar··on Show HN: A Claude Code skill to analyze your chess games
That’s kind of ridiculous, literally all SKILL.md files are almost entirely AI written.
cdelsolar··on Show HN: A Claude Code skill to analyze your chess games
I have an LLM explainer for my scrabble AI Macondo. It’s actually pretty decent. The prompt contains a lot of data straight from the Monte Carlo simulations and other analyses. So it’s not just hallucinating things.

This skill is a great idea. I’ve been trying to figure out how to integrate this with Woogles.io for automatic game analysis.

cdelsolar··on How to keep enjoying programming in a world of LLMs
Yeah I don’t understand. This is late 2026. Opus 5.5 can literally build anything I throw at it. We’re still seeing people who have not been satisfied with _any_ AI generated code?

cdelsolar··on Mom Gets 6-Mo Suspended Sentence for Letting 5-Year-Old Walk to the Pond
my dad and mom grew up in Peru and they tell me that at that age they were basically outside all day, getting lost in the woods, taking buses to the soccer stadium, etc etc. IDK - my son is about to turn 5 and we do helicopter him a bit, ... there needs to be a healthy balance.

cdelsolar··on Claude Fable 5.1 and Claude Mythos 5.1
No second reason; checked not recalled -- it's just saying that it is checking this instead of trying to remember it (there's probably some internal Claude / Claude Code system instruction to always check code instead of remembering)
cdelsolar··on Claude Fable 5.1 and Claude Mythos 5.1
this sounds very much correct and i don't really mind it for that reason. i do a lot of long-running tasks and i feel like it can really pick up on its own thread easier if i just let it write in its own way.

i am also using Opus for a hobby teaching agent, and the way it writes the prompts is "cringy" but they seem to work well. i almost want it to continue doing this internally, it understands best this way.

cdelsolar··on Aphantasia Beginner's Guide
Yes I agree, for me visualizing something has nothing to do with whether my eyes are open or closed because they’re visualized by a different part of the brain..
cdelsolar··on Aphantasia Beginner's Guide
Right exactly. Now I don’t know if I have aphantasia after reading these comments. I have no problem visualizing things, I just don’t “see them” like I would see a pretzel in front of me. Are you saying when you visualize a pretzel you’re literally seeing a brown pretzel with salt grains or are you just imagining that you see it? If you tell me to visualize a pretzel I can sort of imagine the physical shape and color and texture of a pretzel but I don’t really “see” it.

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)
