What Edu is reading this week (Jul 5 - 11, 2026)

A week of DIY NAS builds and ZFS tooling, new frontier model releases from OpenAI and xAI, clever local inference tricks, and a couple of serious virtualization and AI-agent security stories.

AI, Models & Agents

• GPT-5.6: Frontier intelligence that scales with your ambition: OpenAI’s latest release, pitched on more intelligence per token and stronger performance per dollar.
• Introducing Grok 4.5: xAI’s smartest model yet, built for coding, agentic tasks, and knowledge work.
• Introducing the OpenClaw Foundation: OpenClaw becomes a non-profit, with a full-time team and a mission to bring personal AI to everyone.
• JustVugg/colibri: Run GLM-5.2 (744B MoE) on a 25GB-RAM consumer machine — pure C, zero dependencies, experts streamed from disk.
• MTPLX / youssofal/MTPLX: A free, open-source Mac app that runs local LLMs up to twice as fast using native MTP speculative decoding on Apple Silicon, no external drafter needed.
• teamchong/pxpipe: Cut Fable 5 token usage by rendering text context as images.
• stefanprodan/cctop: A live top-style monitor for Claude Code sessions.
• Repomix: Pack your entire codebase into AI-friendly formats for feeding to LLMs.
• langchain-ai/openwiki: A CLI that writes and maintains agent documentation for your codebase.

Cloud, Kubernetes & Infrastructure

• mihaigalos/git-change-operator: A Kubernetes operator for syncing resources or query results to Git via GitCommit/PullRequest custom resources.
• menlocloud/stratos: A multi-tenant billing and self-service portal for OpenStack clouds, with a Go API and built-in AI agent integration via MCP.
• Zuck saves Meta bucks by reusing memory from old servers with a custom CXL ASIC / Panmnesia boosts CXL scale with fabric switching: Meta repurposes DRAM from decommissioned servers via a custom CXL ASIC — in production on millions of boxes with a 25% reduction in machines for some inference workloads.

NAS, Storage & Homelab

• NASdisks: Filter currently-sold NAS hard drives by CMR/SMR, capacity, class and real-world failure rates from Backblaze data.
• OpenZFS Capacity Calculator: Plan your pool layout and see usable capacity for different RAIDZ configurations.
• Building a custom NAS with Fedora CoreOS: A free NAS build with used disks and parts from a previous PC, running on Fedora CoreOS.
• How to Build a Minimal ZFS NAS without Synology, QNAP, TrueNAS: If you don’t care about GUI features, it is surprisingly simple to set up a ZFS dataset and share it over Samba.
• DIY NAS on NixOS: Another take on the DIY NAS, this time declaratively configured with NixOS.
• kldload — pick your distro, get ZFS on root: One ISO that installs CentOS, Debian, Ubuntu, Fedora, RHEL, Rocky, Arch or FreeBSD with ZFS on root, WireGuard and eBPF — offline and free.
• 10 Cheap AliExpress Zigbee Smart Buttons Tested: The ten cheapest Zigbee smart buttons from AliExpress, tested for latency, build quality and Zigbee performance.

Linux & Systems

• ‘I’m not a programmer’ anymore: Linus Torvalds on the only two tools he uses now: Torvalds at the Open Source Summit in Mumbai on the pain and power of AI in the kernel, and why Linux no longer supports “museum” technology.
• Interview With Mitchell Hashimoto: The Ghostty and Terraform maker and HashiCorp founder talks about open source, terminals and Zig.
• Hannah Montana Linux gets modern remaster after nearly two decades: The new v26 is built on Debian with a re-skin of KDE Plasma — a chance to catch up with 18 years of security patches.
• T00fy/omanix: A NixOS module inspired by Omarchy.
• News about Linux (Crostini) on ChromeOS: Google’s news feed for Linux development environments on ChromeOS.
• b-aaz/bmake-extravaganza: Pushing BSD-make to places it was not designed for.
• MacSurf — the modern web, on a 25-year-old Mac: A real web browser for Classic Mac OS 9 PowerPC — CSS3, modern JavaScript and native HTTPS, built with CodeWarrior on the Carbon API.
• Davit — a native macOS UI for Apple containers: Free, open-source and fully native — run Linux containers on Apple silicon with Apple’s container platform, no Docker Desktop required.

Security

• 16-Year-Old Linux KVM Flaw Lets Guest VMs Escape to Host: “Januscape” abuses KVM shadow MMU page reuse to panic x86 hosts on Intel and AMD, with a controlled full-escape exploit reported.
• CVE-2026-57589: A use-after-free in OpenBSD’s sys_semget() (through 7.9) allowing local privilege escalation to root — CVSS 7.8.
• Decades-Old Bash Tricks Expose AI Coding Agents To Supply Chain Attacks: “GuardFall” uses shell behaviors like quote removal and variable expansion to bypass safeguards in most open-source AI coding agents.
• Red teamers turned Claude Desktop into a double agent: People trust their AI assistants, and it’s easy to abuse this trust.

Gaming, Fun & Misc

• Solo Dev’s Train Sim Is Being Called The Best Ever Made: Steam reviews are blowing up for Running Train, a gorgeous Japanese train driving simulator made by one person.
• Quakeworld Air Physics: A classic write-up on the math behind QuakeWorld’s air movement — why bunny-hopping and strafe-jumping work the way they do.
• Can you run every line of code in Super Mario Bros.?: An attempt to execute every line of code in Super Mario Bros., including bytes inaccessible under normal play.
• MaximeRivest/riddle: The diary of Tom Riddle for the reMarkable Paper Pro — write with your pen, the page drinks your ink and answers in a flowing hand.
• An obfuscated bash script on a Uniqlo t-shirt: Decoding the self-evaluating bash script printed on a Uniqlo x Akamai t-shirt — it turns out to be an animated “Peace for All” easter egg.
• Ubisoft Barcelona Celebrates Successful Assassin’s Creed Black Flag Resynced Launch With Layoffs: 51 employees, many of whom worked on the remake, laid off right after launch.
