Passing DBs Through Continuations
Hacker News (AI keywords)7 days agoTutorialThe post explains how continuation-passing style can express database operators without materializing intermediate results. Using Prela and Julia examples, it shows list transformations, relational composition, product, scan, and probe being expanded through inlining. The result is modular query code that can compile into tight columnar loops, though the author notes assumptions around JIT cost and dense primary keys.

Warren's Abstract Machine: A Tutorial Reconstruction
Hacker News (AI keywords)8 days agoTutorialThis repository preserves Hassan Ait-Kaci’s out-of-print tutorial on the Warren Abstract Machine, a key execution model for Prolog and logic programming systems. It is not a new AI model or product launch, but a useful historical and educational resource. The material is most relevant to developers and researchers interested in symbolic AI, compilers, unification, backtracking, and logic language runtimes.
Transformers are inherently succinct★ 74
Hacker News (AI keywords)9 days agoPaperThis paper studies transformer expressivity through succinctness: how compactly a formalism describes a language. It proves fixed-precision transformers can be exponentially more succinct than LTL and RNNs, and doubly exponentially more succinct than finite automata. The same succinctness makes verification hard, with basic problems such as emptiness and equivalence shown to be EXPSPACE-complete.
Tiny hackable CUDA language model implementation
Hacker News (AI keywords)9 days agoNew ToolThis GitHub project implements a compact generative pretrained transformer as an autoregressive byte-level sequence model. Its README describes causal self-attention, RoPE, feed-forward layers, AdamW, cross-entropy training, and BLAS/OpenBLAS-backed matrix operations, with CUDA toolkit listed in setup steps. It is most useful as an educational and experimental codebase, not as a production-grade replacement for large commercial LLMs.

Arithmetic Without Numbers: How LLMs Do Math
Hacker News (AI keywords)9 days agoCommentaryThe article asks whether LLM arithmetic is memorization, heuristics, real computation, or experimental assistance. It summarizes Rune experiments that decode operations and operands from frozen Llama activations, then route them to Python under a no-parser rule. The strongest supported claim is narrow: activation-derived tool arguments worked in scoped audits, while residual-state JIT replacement, long-number generation, and cross-model transfer remain brittle.
MIT Develops Electrochemical CO2 Capture Using NHI Molecules

How LLMs Actually Work
Hacker News (AI keywords)10 days agoTutorialThe article explains how modern LLMs convert text into token IDs, embeddings, and position-aware vectors before passing them through stacked transformer blocks. It covers attention, multi-head attention, KV cache, GQA, feed-forward networks, MoE, residual streams, normalization, and decoding. Its goal is educational: helping readers understand the common architecture behind many current model families and read model cards or papers more confidently.
How Embryos Shape Their Limbs: A Key Discovery of Genetic Brakes
Hacker News (AI keywords)11 days agoPaperA Université de Montréal and IRCM team reports in PNAS that Polycomb complexes PRC1 and PRC2 act as genetic brakes during mouse limb development. These systems silence early developmental genes so later programs can proceed. Disrupting one system alters gene expression; disrupting both keeps early genes active and severely compromises normal limb formation.
Spherical Voronoi Diagram
Hacker News (AI keywords)11 days agoTutorialJason Davies’ page demonstrates a spherical Voronoi diagram, where seed points divide the surface of a globe into nearest-neighbor regions. It relates the visualization to circumcircles and Delaunay triangulation. The implementation notes say it uses a randomized incremental algorithm to compute the 3D convex hull of spherical points, equivalent to their spherical Delaunay triangulation, and that the project remains a work in progress.
