Inside Slipstream’s Recall Pattern
Glide’s engineering team explains Slipstream’s recall pattern for handing six types of rote engineering maintenance work to AI agents: how issues are detected, recalled into agent workflows, verified, and measured, with the numbers they are seeing in production.

Fun Extending the C Preprocessor
David Priver, who is writing his own C2Y compiler/interpreter/REPL, shows extensions he added to its C preprocessor, including __print() and __where() debugging builtins, a native __map() that replaces recursive macro hacks, and __VA_COUNT__ for counting variadic arguments.

Making 1,750 programmable PCB badges for Canada's biggest hackathon
Nick Ficara tells how Hack the North's cardstock name tag became 1,750 programmable circuit-board badges with a screen, buttons and radio, walking through EVT, DVT and PVT prototypes, part-selection errors, flipped ICs, supply chain and the production run, with open-source hardware, firmware and a WebAssembly emulator.

Everyone is doing Git on S3 wrong
Enroute explains why Git is hard to put on object storage, where write-ahead-log designs fall short, and how its Rust, Raft and S3-backed Git server, built on modern database principles, reaches 7,600+ concurrent pushes per second on a single repository, with benchmarks and an open-source 0.3.0 release.

How Cogent Runs Cloud Agents Securely
Cogent's engineering team describes how it runs cloud security agents assuming the sandbox may be compromised: trusted systems outside the sandbox control credentials, network and data access while still letting agents verify their work.

Why I Started Moving Inference In-House
Nicholas Reese explains why he moved the AI behind USA Arms onto in-house hardware — three servers with four AMD Radeon AI PRO R9700 cards each — covering costs, the parts list, the build video, and a free build guide meant to hand to an AI.

Linux Lockdown and Hibernation (again)
Matthew Garrett revisits why Linux kernel lockdown disables hibernation, how a hibernation image could be used to tamper with a locked-down kernel, and updated technical approaches using TPM-sealed keys to make secure hibernation possible.

We turned EmbeddingGemma 2 into a speech-to-text model
Google's EmbeddingGemma 2 is a multimodal embedding model; this write-up shows how a small trained reader turns its audio encoder into on-device speech-to-text—about an hour of audio in ~13 seconds on a base MacBook Air—without retraining the base model for ASR.

Please stop hashing the public key first (or: ML-DSA's µ annoys me)
Erincandescent explains why signature schemes such as Ed25519 and ML-DSA hash the public key before the message, why that ordering blocks a useful optimisation for verifying one message against many candidate keys, and how the constructions could have been arranged differently.

How we built the AssetHoard MCP server
AssetHoard’s Mark Gandolfo explains how the library’s built-in MCP server lets Claude Code, Cursor, and other agents search owned game assets and export into a project—and why the server is locked down so file contents stay on the user’s machine.

One-shotting an Unreal Engine plugin from a 3,000-line plan
Jack Minnetian describes writing a 3,000-line plan for a voxel painting tool in Unreal Engine, handing it to an agent that returned more than 25,000 lines in fourteen hours, and what the success and failure modes say about plan-driven coding agents.

Rewinding the exponential: How we keep hardware usage down
Cloudflare’s Data team explains how it reined in an exponentially growing analytics pipeline—rewinding retention, compression, and query patterns—so hardware and cost stay sustainable while more than 20% of the web sits behind its network.

Redesigning source control at Anthropic
Anthropic explains how merges to its monorepo grew from about 2,500 to over 30,000 per day in 2026, why git hosting became the bottleneck, and how it built and migrated to Scion, an in-house version control system, in five months, plus lessons and ideas for the wider git ecosystem.

We kept renting GPUs after getting 7 quotes to buy them
Agora's Param Jaggi walks through seven vendor quotes from Madrid resellers, colocation providers and a carrier for buying GPU servers, and the cost model showing that $354,100 of hardware would take until year nine to beat renting two servers for $7,200 a month, plus advice for teams weighing the same decision.

My Reddit AMA on the Law of Web Scraping
Law professor Eric Goldman shares his introduction to a Reddit AMA on US web scraping law: the social benefits and harms of scraping, why trespass-to-chattels law is a mess, and why a scraping campaign must survive many doctrines, from contracts to copyright, to be legal.
