What Edu is reading this week (Sep 12 - 19, 2026)

Agent infrastructure dominated the week: Kubernetes-native harnesses, a high-density sandbox runtime on GKE, and a 27B model compressed into under 6 GB. Alongside that, BSD filesystem work, PipeWire audio tooling and a batch of retro-gaming archives.

AI, Agents & Tools

• llmman - Runs any agent on any model, with the models themselves stored and shipped as OCI images.
• Mecatl - Stacklok’s open source, cloud-native harness for agents: the agent loop, the sandbox and the state are separate components, so a fleet runs on Kubernetes instead of on your laptop.
• Agent Substrate available on GKE / agent-substrate/substrate - Google’s open source, high-density agent runtime, which it says scales to millions of sandboxes per cluster.
• Anthropic’s Hidden Vercel Competitor “Antspace” - Reverse engineering the Claude Code client to find the deployment platform behind it.
• I Came, I Prompted, I Left Part 1 - A custom hypervisor for the MacBook Neo, built to trace how macOS talks to Apple Silicon, mostly through unattended LLM loops.
• archify - An agent skill that turns a description into architecture, workflow and sequence diagrams as self-contained HTML, with dark/light themes and SVG/PNG export.
• PrismML: Bonsai 2 27B - A ternary-compressed 27B model that keeps 98.2% of Qwen3.8 27B’s benchmark results in a 5.9 GB footprint.
• mimo-v2.6 RL - Live training metrics from the reinforcement learning runs behind Xiaomi’s mimo-v2.6-pro and mimo-v2.6-flash.
• SemIf — local decisions in your browser - Jev’s System One model running locally on WebGPU, returning typed option logits and autoregressive JSON.
• awesome-jev / Made with Jev - A curated list of Jev use cases, SDKs and resources, plus a directory of projects built with it and the cost and speed each author reported.
• mysetup.ai - Publish your own AI setup and browse how other people run theirs.

Cloud, Kubernetes & Storage

• When is a cluster really full? / k8s-overcommit-operator - Inditex’s operator for overcommitting pod resource requests, plus the write-up of how it halved microservice replicas through a 2025 demand peak.
• RustFS 1.0.0 GA - An Apache-2.0, S3-compatible distributed object store written in Rust reaches general availability.

Linux, BSD & Systems

• Crash-Safe & Copy-On-Write GEFS for OpenBSD / ‘GEFS on OpenBSD: A very early preview’ - Ori Bernstein’s “good enough filesystem” now runs on OpenBSD, with the mailing-list post clear that it is a preview and not ready for production.
• shithub: the fragrant git host - A Git host running git9 on 9front, where ori and other Plan 9 projects keep their repositories.
• Coreutils - rejected feature requests - The features coreutils has turned down over the years, with the reasoning behind each rejection.
• wwmm/easyeffects - Limiter, compressor, convolver, equalizer and auto-volume plugins for PipeWire applications.
• omarchy-speaker-calibrator - Measures your speakers with a microphone and generates a validated, protective parametric calibration for the Omarchy bar.
• nixarchy - Omarchy 4.x vendored for NixOS as a derivation rather than reimplemented in Nix.

Hardware & Homelab

• Converting a $20 4G wireless hotspot into a texting device - An OpenStick-compatible MF800 hotspot turned into something that can send SMS, assembled from parts already lying on the desk.
• EchoMuse - An Alexa replacement and local controller for the second-generation Echo Dot.

Security & Privacy

• LG statement on smart TV privacy - LG’s answer to the recent coverage: wake-word audio is processed locally and discarded, ACR is opt-in and off by default, and voice sessions are time-limited, with consent managed in TV settings.

Gaming & Retro

• Sega Rally 2 ~ 25th Anniversary Edition - A repack of the Dreamcast rally racer, in English, Spanish and Japanese.
• X-Men Origins: Wolverine - Uncaged Edition - The uncut 2009 tie-in game, archived for download.
• The Gran Turismo Magazine: “Beyond the Apex” - The promotional magazine that shipped with Gran Turismo 6.
• I am stepping away from the PS5 Linux scene - Andy Nguyen (theflow0) stops his PS5 Linux work, PS5 Pro support included.
