  1. Reverse-engineered Jev-like model

    Jevlike is an open‑source starter model that scores a list of text options in a single forward pass. It provides a minimal architecture (option queries, shared dot‑product scorer), synthetic data generation, training/evaluation CLI, and examples on Doom and chess. The repo supports a byte‑level encoder or a frozen Hugging‑Face encoder (e.g., Qwen2.5‑0.5B), runs on CPU/MPS/CUDA, and reports benchm…

  2. Vectorized and performance-portable Quicksort (2022)

    Google’s Highway library now includes a fully portable SIMD‑vectorized quicksort that runs 9‑19× faster than C++ std::sort. By using compress‑store (or permute‑based emulation) for partitioning, the same C++ code targets AVX2, AVX‑512, NEON, SVE and RISC‑V V. Benchmarks show 0.5 GB/s on an Apple M1 and >1 GB/s on a 3 GHz Skylake, beating prior architecture‑specific sorts. The implementation and a…

  3. Claude Cowork and chat are now one Claude

    Claude merges its Cowork and chat interfaces into a single assistant and adds beta Docs, Slides, and Design capabilities, rolling out first to Pro and Max plans. The unified UI lets users ask Claude to generate reports, presentations, and other artifacts within the same conversation, with optional auto‑action settings. No new technical details or implementation specifics are provided.

  4. Can we stop with the uptime percentages?

    This article argues that uptime percentages are a poor public interface for communicating service reliability because their non-linear nature is not intuitive to non-infrastructure people. It proposes showing absolute downtime (e.g., hours affected) alongside percentages for better clarity for a general audience.

  5. The DeepMind Institute

    DeepMind announced the DeepMind Institute to foster interdisciplinary thinking on the profound implications of AGI. It highlights initial essays covering AI reasoning transparency, economic policy for AGI, principles for a new utopianism, and a framework for frontier AI testing.

  6. Anatomy of a Texture

    A practical deep‑dive into modern texture memory layout: block‑compression (BC7), swizzle ordering (Morton/Z‑order), mip‑map hierarchies, and concrete debugging tricks for cross‑platform texture conversion.

  7. Hackers Got Inside a Flock Camera

    Hackers removed a Flock license‑plate reader camera, copied its storage, extracted an on‑device encryption key, and released ~1.6 M images and logs covering 21 days of operation. Analysis shows the device captures ~28 images per vehicle, detects people, and stores raw media in unencrypted partitions. License‑plate detection runs on the cloud, and the camera’s software can mis‑identify graphics as…

  8. Wax motor

    Wax motors are linear actuators that turn thermal energy into mechanical motion via wax phase change. They consist of a wax chamber, a plunger, a heat source (electric, solar, combustion, ambient) and a heat sink. Wax expands 5‑20% on melting, delivering forces up to ~4000 N, with a bias spring providing 20‑30% of that force for retraction. Advantages include high force density, smooth actuation,…

  9. Nvidia announces native GPU programming in Rust

    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…

  10. Negativland, Culture Jamming, and the Art of Making Something New

    Negativland is a long‑running experimental sound collage collective that coined “culture jamming” and has built a niche audience through DIY releases, legal battles over sampling, and a massive archive of their freeform radio show. Their recent live show at the Internet Archive highlights remote collaboration and ongoing preservation efforts, but the piece offers no technical insight for software…
