Retro Computing & Emulation

Marty PC has landed on GitHub as a cycle-accurate IBM PC/XT emulator written in Rust, targeting the kind of timing precision that matters for demos and copy-protected software. Meanwhile, a forum veteran has recounted building a working GPS navigation setup on a 25MHz 486-SX back in 1993, a reminder of how much was once accomplished with so little. On the FPGA side, one builder has recreated Voodoo Graphics alongside a full late-1990s gaming PC using a Z486 CPU core, reviving 3dfx-era rasterization in programmable logic.

AI Tooling & Agent Infrastructure

Datamimic has published a framework for synthetic test data aimed at regulated industries, explicitly pitched as a way to stop coding agents from inventing their own test worlds. The team behind System One has introduced Jev, a frontier model they claim is 40-400x cheaper and 20-200x faster than comparable systems. Google has shipped Gemini 3.8 Live along with a Live Extended Thinking variant, expanding the real-time multimodal lineup. Pizza Bot has debuted as an open-source inbox for background AI agents, self-hosted and aimed at long-running autonomous work. Panel offers a research workspace where the agent can construct its own panes, and Ordewell has released a tool that turns a single goal into an ordered plan of coding-agent tasks.

Security & Supply Chain

Baseten has been caught exposing an admin token through a public Harbor registry, giving researchers administrative access to the company's production GitHub. A Reddit thread in r/reinforcementlearning has accused Google of copying open-source code and stripping engineers' names without credit. Hugging Face is reportedly billing OpenAI $100M over an alleged agent-driven hack, a dispute that could set precedents for agent liability. Nvidia's Open Shell team has detailed lessons from applying formal methods to constrain AI agent behavior. A new paper on GRP-Obliteration demonstrates unaligning LLMs with a single unlabeled prompt, underscoring how brittle current alignment techniques remain. Have I Been Proxied has launched a checker that tells users whether their IP has appeared in a residential proxy network.

Privacy, Surveillance & Policy

A Lawfare analysis argues that America's driver's license breach constitutes a national security disaster given the scale of exposed identity data. Cindy Cohn and Bruce Schneier have co-authored a call marking 25 years of mass surveillance and arguing it is more than enough. Schneier has published a companion piece on his own blog expanding the same argument. Cloudflare has rolled out a "disallow AI training" setting designed to keep sites discoverable in search while blocking crawlers that train models. Apple has proposed Reference Image, a new approach to verified photography that aims to establish provenance at capture time.

Open Source & Platform Releases

Rheinmetall has open-sourced the protocol behind its Battlesuite connected weapon system, an unusual move for a defense contractor. Swift 6.4 has been released with a set of new features and improvements. Java 27 has reached general availability per the Open JDK announcement list. The Internet Archive has posted an update on Wayback Machine access, following recent availability disruptions. Separately, the Archive has celebrated Negativland, marking 46 years of culture jamming and audio collage art.

Systems, Networking & Performance

RIPE Labs has published work on Grand, an effort to close the IPv6 first-packet gap that has long penalized v6 connections on latency-sensitive workloads. An early preview of GEFS has appeared on OpenBSD, posted to the openbsd-tech mailing list. A developer has documented writing a Linux GPU driver for the M4 Mac Mini in roughly one month. A separate writeup explores rebuilding Firefox.com with native CSS, framed as the CSS Zen Garden dream finally shipped. Capsule has launched as a way to build single-file web apps that persist their data directly into SQLite. IEEE Spectrum has surveyed the inference hardware revolution unfolding through 2026.

Research & Machine Learning

A new ar Xiv paper examines the Matthew effect in RL for LLMs, arguing that never giving up on hard problems is itself a learnable strategy. A blog post argues the author remains bearish on LLMs even after recent Navier-Stokes results. Byte Byte Go has published an explainer on how LLMs handle memory and why context management remains the central constraint. Byte Byte Go is also relaunching its Claude Code course as a two-day intensive cohort, with enrollment closing. Jean-Pierre Serre has turned 100, and the Mac Tutor archive has published a retrospective on his career. Numberwang has been reimplemented as WangNet, a 1.8MB zero-dependency adjudicator covering 11 languages.

Hardware Hacks & Curiosities

One hacker has turned a $20 4G hotspot into a working texting device. Fugleramme is an e-ink frame for the Raspberry Pi that listens for birds and draws them in the style of 1800s illustrations. A PNAS Nexus paper applies physics and differential equations to the design of splash-free urinals. Matt Kirkland has written about chopping up books that are physically too large to read comfortably. Cartesian from Formas AI has launched as an AI 3D modeling tool aimed at design workflows. Marksblogg has detailed an open-source approach to flight-path optimization using scikit-decide and Open AP that reduces jet fuel burn.

Business, Geopolitics & Hiring

OpenAI has acquired Glass Imaging, a smartphone camera maker, for $300M. Australia is seeking a deeper EU alliance and says it is on the same page as Canada on the matter. Suspected sabotage has caused major rail disruption in the Netherlands, hitting Amsterdam services. Jiga, a YC W21 company, is hiring a product engineer for a remote US role to build manufacturing software.
