My friend Milla Jovovich and I spent months creating an AI memory system with Claude. It just posted a perfect score on the standard benchmark - beating every product in the space, free or paid. It's called MemPalace, and it works nothing like anything else out there. Instead of sending your data to a background agent in the cloud, it mines your conversations locally and organizes them into a palace - a structured architecture with wings, halls, and rooms that mirrors how human memory actually works. Here is what that gets you: → Your AI knows who you are before you type a single word - family, projects, preferences, loaded in ~120 tokens → Palace architecture organizes memories by domain and type - not a flat list of facts, a navigable structure → Semantic search across months of conversations finds the answer in position 1 or 2 → AAAK compression fits your entire life context into 120 tokens - 30x lossless compression any LLM reads natively → Contradiction detection catches wrong names, wrong pronouns, wrong ages before you ever see them The benchmarks: 100% recall on LongMemEval — first perfect score ever recorded. 500/500 questions. Every question type at 100%. 92.9% on ConvoMem — more than 2x Mem0's score. 100% on LoCoMo — every multi-hop reasoning category, including temporal inference which stumps most systems. No API key. No cloud. No subscription. One dependency. Runs on your machine. Your memories never leave. MIT License. 100% Open Source. github.com/milla-jovovich…

Why are you here? "We're going back to the fucking moon, that's why." The kids are ok.

Yes... In case anyone was wondering, Microsoft still sucks in space.

My dear front-end developers (and anyone who’s interested in the future of interfaces): I have crawled through depths of hell to bring you, for the foreseeable years, one of the more important foundational pieces of UI engineering (if not in implementation then certainly at least in concept): Fast, accurate and comprehensive userland text measurement algorithm in pure TypeScript, usable for laying out entire web pages without CSS, bypassing DOM measurements and reflow

I've plotted the most expensive McDonald's burger and the least expensive MacBook over time. This analysis projects that the most expensive burger will be more expensive than the cheapest laptop as soon as 2081

“We used to review every line of code before it went into production”.

Moltbook is wild.

Miriad is hiring a @rescriptlang developer with strong UI/UX focus. Also good opportunity to work on open source as well 🚀 👉forum.rescript-lang.org/t/miriad-is-hi…

Me defending my O(n^3) solution to the coding interviewer.

This.

The LLM-written README style guide: - Too many headers - Too many emojis - Too much bold (especially at the front of each list item) - Too many parentheticals (especially at the end of each list item)

AI model of today is not the AI model of tomorrow.

Like @davidbessis and others, I think that Hinton is wrong. To explain why, let me tell you a brief story. About a decade ago, in 2017, I developed an automated theorem-proving framework that was ultimately integrated into Mathematica (see: youtube.com/watch?v=mMaid2…) (1/15)

Another day in the algorithmic art studio.

ReScript 12 is here! A major step toward a leaner, faster, simpler toolchain. This release refines the language and embraces ReScript’s own identity. Blog: rescript-lang.org/blog/release-1… Notes: github.com/rescript-lang/… Huge thanks to everyone who helped move ReScript forward.

How do you acquire the fundamental computer skills to hack on a complex systems project like OCaml? What’s missing and how do you go about bridging the gap? kcsrk.info/ocaml/2025/11/… Wrote the list for my students, but it may be useful for others too.
