#1Zed is 1.0

Zed, the GPU-accelerated code editor built in Rust, hits its 1.0 milestone after five years of development with deep AI integration at its core. It supports running multiple AI agents in parallel, features edit prediction at keystroke speed, and implements the Agent Client Protocol for plugging in Claude and other models natively. The team is building DeltaDB, a CRDT-based sync engine for real-time collaboration between humans and AI agents on shared codebases.

#2Letting AI Play My Game – Building an Agentic Test Harness

A game developer built a text-based test harness around his puzzle-RPG "Crossword Dungeon" so Claude could actually playtest it — not just exercise code paths, but genuinely play. The AI implemented and tested five complex encounter features in 12 minutes using 120k tokens, independently discovering bugs, creating repro fixtures, and fixing code. This cut manual playtesting from hours to under 30 minutes, demonstrating a practical blueprint for AI-assisted game QA.

#3Tangled – We Need a Federation of Forges

Tangled is a federated code collaboration platform that lets developers host repos on independent git servers ("knots") while enabling cross-server pull requests and forks. It uses the AT Protocol (from Bluesky) for social and development activity communication alongside standard git for code transfer. The project directly challenges GitHub's centralized model, arguing that distributed systems historically outlast centralized ones.

#4HashiCorp Co-Founder Says GitHub 'No Longer a Place for Serious Work'

The Register's coverage of Mitchell Hashimoto's decision to migrate Ghostty off GitHub, framing it as a broader indictment of the platform's reliability for production open-source work. Hashimoto maintained a daily outage journal showing near-constant service disruptions, particularly GitHub Actions failures that blocked PR reviews for hours. He's evaluating both commercial and FOSS alternatives while planning an incremental migration.

#5Ghostty Is Leaving GitHub

Mitchell Hashimoto's firsthand account of why he's moving Ghostty off GitHub after 18 years on the platform — chronic, near-daily outages that block productive work. His outage journal documents persistent GitHub Actions failures, pull request issues, and infrastructure incidents that make shipping software unreliable. The specific destination hasn't been announced, but a read-only GitHub mirror will remain.

#6Bugs Rust Won't Catch

An analysis of 44 CVEs discovered in uutils (a Rust rewrite of GNU coreutils) showing that Rust's memory safety doesn't prevent logic errors at system boundaries. Key vulnerability classes include TOCTOU race conditions in filesystem operations, improper UTF-8 handling that corrupts binary data, and panics on untrusted input causing denial of service. The takeaway: the compiler handles memory safety, but developers must still handle the messy boundary between their program and reality.

#7Soft Launch of Open-Source Code Platform for Government

The Dutch government launched code.overheid.nl, a self-hosted Forgejo instance enabling government organizations to collaboratively develop and publish open-source software while maintaining digital sovereignty. The platform is positioned as a European, sovereign alternative to GitHub and GitLab, led by the Ministry of the Interior's Open Source Program Office. It's currently a limited pilot with invitations being extended to interested developers and government bodies.

#8Adblock-rust Manager – Firefox Extension to Enable the Brave Ad Blocker

A Firefox extension that provides a UI for managing Firefox 149's hidden built-in ad-blocking engine — Brave's open-source, Rust-based content blocker that Mozilla shipped disabled by default without documentation. It supports network request blocking, cosmetic filtering, and is fully compatible with uBlock Origin filter list syntax. The extension lets users toggle enhanced tracking protection and manage filter lists including EasyList and EasyPrivacy.

#9Improving ICU Handovers by Learning from Scuderia Ferrari F1 Team

Great Ormond Street Hospital redesigned critical patient handovers from surgery to ICU by adopting Ferrari F1 pit stop methodology — a four-stage process with pre-arrival prep, silent equipment setup, structured verbal handover with checklists, and team discussion. Evaluation across 50 handovers showed improvements in every dimension: equipment transfer, teamwork, information exchange, and duration. The human factors approach of layering multiple reinforcing elements proved more robust than any single-solution fix.

#10DOS 1.0: Transcription of Tim Paterson's DOS Printouts

A historical preservation project transcribing Tim Paterson's physical printouts of early DOS source code from the 1980s, including the 86-DOS 1.00 kernel, PC-DOS pre-releases, and Microsoft BASIC-86 runtime libraries. The transcriptions progress through three stages: raw transcription, extracted original files, and compilable source code. It's a valuable computing archaeology effort preserving the foundational code of the operating system that dominated IBM-compatible PCs.
