Reproduces Mold’s linker benchmarks on a 16‑core Ryzen, shows that configuration (filesystem, delete‑output, fork) explains most of the Wild vs Mold speed gap, and notes recent Mold releases and upcoming Wild tweaks that close the gap.
Built a clean‑room OpenGL ES 3.0 Linux driver for Apple‑silicon M4/A18 Pro GPUs in ~4 weeks, covering reverse‑engineered firmware ABI, a Rust kernel driver, a custom IR/shader compiler, and user‑space Metal translation; achieved 200 fps Minecraft and WebGL demos, with heavy LLM assistance for debugging and code generation.
NVIDIA released CUDA‑Rust, letting you write GPU kernels directly in Rust and compile to PTX. Two programming models are supported: the traditional SIMT model via the `cuda-oxide` backend (nightly Rust, custom codegen) and the newer Tile model via `cutile‑rs` (stable Rust, JIT‑compiled Tile IR). Both provide Rust‑typed safety guarantees (e.g., `DisjointSlice`, tensor partitioning) and simple Carg…
IBM’s Harvest (IBM 7950) was a 1960s NSA‑dedicated streaming coprocessor attached to an IBM Stretch mainframe. It ran up to 200× faster than contemporary machines, used a custom bit‑addressable memory model, pipelined parallel streams (P, Q → R), and introduced the world’s first automated tape library. IBM also created a domain‑specific language, Alpha, for cryptanalytic programmers. The article…
mini-AGI is a byte‑level continual‑learning language model that fits on a single 8 GB GPU by paging expert weight files from disk. It uses two dense prelude blocks followed by a recurrent block applied up to 24 times per character, with adaptive depth (PonderNet halting) and per‑application top‑8 expert routing. The system maintains a RAM cache and a VRAM resident set, swaps experts based on dema…
A Rust veteran recounts porting a JSONPath library to Zig, highlighting differences in IDE support, project layout, testing ergonomics, functional vs imperative idioms, and Zig's explicit allocator model.
The author built a full graphical desktop for the 48 KB ZX Spectrum in Z80 assembly, fitting overlapping windows, menus, input handling, and a heap within a single frame. All performance claims are backed by measurements taken on real hardware.
The author shows how to label tokens (dates, money, emails, etc.) with a single regex pass using extended operators (`&` for intersection, `~` for complement) in the resharp library. A tiny benchmark compares 10 patterns against spaCy’s NER, reporting ~1.9 GB/s (≈4500× faster) on 8 threads. The post lists the concrete patterns and argues that for deterministic, regular‑language entities regex can…
ScienceIDE is a framework that turns existing scientific software repositories into programmable environments that agents can use for task generation, execution, and verification. Training on these environments yields LLMs (PhAI‑IDE series) that outperform baselines on scientific code repair and several general code‑reasoning benchmarks.
Go 1.27 adds a set of span‑class‑specific malloc functions for allocations ≤ 80 bytes. By generating a tiny, constant‑size allocator per span class the runtime can inline size‑dependent work (e.g. zero‑clear) and skip span‑class lookup, yielding 20‑30 % faster small allocations and ~1 % overall speed‑up for allocation‑heavy programs. The implementation is generated automatically via an AST inline…
A community‑maintained fork of the Motif X11 UI toolkit (https://github.com/thentenaar/motif) has released five versions in its first year, incorporating long‑stale upstream fixes and Gentoo patches. The original Motif project on SourceForge has been inactive for over two years, but this fork aims to keep Motif and related X11 components alive, hoping to eventually support a niche desktop environ…
Guix-Modules is a new tool that generates Environment Modules files from Guix packages, allowing HPC users to leverage Guix's reproducible software environments with their familiar `module` command interface. This bridges the gap between traditional HPC environment management and Guix's declarative, reproducible approach.
The author details building MoonForth, a Forth interpreter written in C that leverages Lua's C API for stack manipulation and word storage. The process was surprisingly straightforward, reinforcing the idea that Forth "writes itself" by iteratively filling missing functionality.
A hobbyist restored a Mentec M11‑based PDP‑11/83 running 2.11BSD, exposing a live status panel that shows CPU, memory, bus, storage, and networking activity while serving this web page.
ModularRSI proposes a contrastive, modular approach to evolve agent harnesses by independently updating five functional modules and aggregating evidence across 2,000 benchmark‑disjoint tasks. Experiments on TB2.0 and SWE‑Bench Verified show consistent gains on unseen tasks and cross‑model transfer.
NVIDIA showcased new power‑aware AI‑factory features at the AI Infra Summit. DSX MaxLPS and Flex improve token‑per‑watt efficiency by up to 40%, while the Vera Rubin NVL72 platform delivers up to 30× higher throughput per megawatt on agentic workloads.
Meta open‑sourced Rebalancer, a library that lets engineers describe assignment problems (objects → bins) via a high‑level spec API, then solves them with either a MIP backend or a highly parallel local‑search engine. It handles millions of objects, solves ~40 M problems daily, and includes a debugging UI.
MilleMiglia is an open‑source C++ generator that creates realistic, privacy‑preserving middle‑mile logistics instances (space‑time graphs with fixed schedules, throughput limits, and synchronization constraints). It uses data‑driven spatial, demand, and rotation distributions, serializes with protobuf, and ships small files for small‑toy to continent‑scale problems, enabling both exact/heuristic…
A tongue‑in‑cheek post highlighting an absurd GPL header that repeats "2013" dozens of times, questioning the reliability of the surrounding code.
