Back in the early 1990s, I was hired to build a real-time GPS-driven moving map on a 25MHz 486-SX with 32MB RAM and a 1024x768 display, software stored in ROM. I used the Hipparchus GIS library (Geodesy) that relied on Voronoi cells and heavy integer math with a little floating-point, delivering much faster performance than traditional trig-heavy code. I built a working prototype; the client funded it, but financial issues halted further development, and IP was not retained. This all happened years before consumer GPS devices from Garmin/Magellan, which finally matched its speed by the mid-1990s.

The piece argues that understanding and sometimes doing others' jobs is valuable: it reveals needs, helps when they won't act, and lets you integrate your work into existing systems. It cites Intel’s cross‑functional patching as precedent and warns that many managers resist this 'twisted' charity, though it benefits the organization and the individual who grasps workflows. It notes two risky patterns: over‑building in‑house versus buying, and department‑level projects avoiding centralized services, both affecting outcomes. It ends with Dan Luu’s take on hiring by having done the job and scalability challenges of managing people you can’t do.

Apple introduces Apple Reference Image, an opt-in iPhone mode (iPhone 18 Pro/Pro Max) delivering verifiable photography by binding a cryptographically signed secure digital negative to a timestamped reference image processed in Private Cloud Compute (PCC). The two-stage pipeline signs data at capture in hardware with SEP attestation, then develops the reference image in PCC with public verifiability, using a post-quantum RSA-3072 + ML-DSA-87 signature. It supports sensor revocation, uses privacy-preserving timestamps, and avoids public photographer identity. It sets a new standard for semantic authenticity, resilience, and privacy in image provenance.

Negativland is a long-running multimedia collective that has produced more than 30 albums and related works over 46 years, using sampling and found material to critique media, power, and capitalism—a practice they helped name culture jamming. They gained notoriety with a 1991 U2 sampling dispute that spurred discussions on copyright reform, later documented in Fair Use. The group has expanded into art, books, and radio, notably Over The Edge, now archived by the Internet Archive (4,000+ hours) and revived in live shows such as Over The Edge: Significantly Less Deceptive. They remain audience-focused and collaborative, often performing remotely.

Niklas Gruhn praises roundabouts as a simple, elegant traffic solution that avoids the flaws of traffic lights. He notes traffic lights suffer from deadlock, sensor issues (especially for bikes/motorcycles), and problematic yellow phases, and that adding complexity only compounds problems. Roundabouts require no active control or electricity; they regulate flow passively, so you rarely wait when there’s no traffic and you slow down when approaching. The central island often gets art or greenery, giving character to infrastructure. He also points to a roundabout database with examples.

An FPGA project, zSST, implements the 3dfx Voodoo SST-1 on a KV260 board, paired with a z486 XL DOS PC. Using Glide’s workflow, it renders a fixed-function pipeline for triangles with texture filtering, mipmapping, depth tests, fog, and blending; memory is reorganized with caches, a reorder buffer, and DDR access to keep the pipeline fed. At 100 MHz, zSST reaches ~78.5 MPix/s textured and ~72.8 MPix/s with depth/blend, higher than Voodoo 1’s ~43/37 MPix/s at 50 MHz. Tomb Raider runs; Doom/Quake benchmarks show CPU bottlenecks. The projects are open source.

Colin Colino expands Quicktake for Apple II with modular Sierra-class camera drivers, building on Kodak DC-50 support. Tested with Sanyo VPC-G1/G200, Epson PhotoPC PCDC001, and Sierra Imaging SD640; the Sierra driver exposes 16 API methods and supports info, quality, flash, and taking/getting pictures (thumbnail retrieval exists but isn’t wired to the UI). Serial speed is limited to 19200bps by Apple II ACIA framing issues. Plans include adding more drivers (Canon PowerShot 350), compressing binaries with zx02, and possibly renaming the project while keeping “Quicktake for Apple II.”

XLS is an open-source, experimental High-Level Synthesis toolchain that turns high-level descriptions into synthesizable Verilog/SystemVerilog. It supports pure functions and stateful procs, enabling designs that run natively on host software or simulators and can also generate hardware blocks. Aimed as an SDK for the End-of-Moore’s-Law era, XLS promotes software-style co-design and verification. It’s not an officially supported Google product. The project provides Colab notebooks, binary releases, and Bazel-based builds (with optional Docker), plus caching, Clangd support, and a structured layout of components and contributors.

The post argues there is a Matthew Effect in RL for LLMs: RL gains concentrate on easy problems, while hard ones stagnate. It introduces Never Give Up (NGU), an adaptive sampling method that uses small k for easy prompts and re-samples unsolved prompts with larger rounds (guided by a probability p), effectively allocating more compute to hard tasks. Across math, code, and other domains, NGU improves hard-task performance without hurting easy tasks. It also covers staleness tricks, baseline adjustments, and notes limitations and future directions.

An in-depth look at data races and the limits of ThreadSanitizer (TSan) in C and Go. It explains data-race definitions, then contrasts Eraser and FastTrack approaches (vector clocks, per-granule history) and shows how TSan’s design introduces blind spots. Through concrete examples in C and Go, it demonstrates misses when crossing a 255-thread boundary, budgeted synchronization releases, or 8-byte memory-granule tracking, with Go’s sync.Pool exacerbating misses. The author even builds a Python-based idealized detector to illustrate detection mechanics. Bottom line: TSan is useful but not foolproof; be aware of its budgeted blind spots.
