What Edu is reading this week (Jun 21 - 27, 2026)

A week mixing local LLM tooling, terminal-driven virtualization, OCI registries and PXE boot servers, a few BSD and mobile Linux releases, and some hardware tinkering.

AI, Models & Coding

• microgpt: Karpathy’s minimal GPT implementation in a single gist, for understanding the architecture from the ground up.
• vLLM + LMCache: A Starter Guide, No GPU Required: A contributor-focused walkthrough of vLLM + LMCache on a single MacBook, covering the frontend, L1 eviction, L2 storage, and observability — no GPU needed.
• GLM-5.2 - How to Run Locally: Unsloth’s guide to running Z.ai’s new GLM-5.2 model on local hardware.
• Is AI ruining our skills?: Nature reports on early studies showing that reliance on AI tools degrades the abilities of physicians and software engineers.
• Codex SQLite feedback logs can write ~640 TB/year: An OpenAI Codex issue where the local SQLite feedback log writes a continuous flood of data, rapidly consuming SSD endurance.
• Understand Anything: Turns any codebase into an interactive knowledge graph you can explore, search, and learn from.

Cloud, Containers & Infrastructure

• project-zot/zot: A scale-out, production-ready, vendor-neutral OCI-native container image and artifact registry built purely on the OCI Distribution Specification.
• Deploying OpenClaw on Kubernetes with Helm: OpenClaw’s shell access and untrusted input create real attack surface — this guide deploys it on Kubernetes with Helm and ArgoCD so container isolation and network policies contain the blast radius.
• Running microVMs in Proxmox VE, The Easy Way / VirtUI Manager: Running lightweight microVMs across a mixed Proxmox cluster, plus VirtUI Manager, a next-generation terminal-based UI for managing QEMU/KVM virtual machines.
• Bootimus — Modern PXE/HTTP boot server: A self-contained PXE and HTTP boot server in a single binary with zero config and 50+ distros out of the box.

Linux & Systems

• Announcing NetBSD 11.0 RC5: The fifth release candidate for NetBSD 11.0, out June 16, 2026.
• postmarketOS v26.06: Alpen Avocado: The latest postmarketOS release, aiming for a 10-year life-cycle for smartphones.
• Samsung SSD Firmware: The Gentoo wiki page on updating Samsung SSD firmware from Linux.

Development, Web & Security

• Developers don’t understand CORS: The recent Zoom vulnerability is one of many examples showing how poorly CORS is understood, with a clear walkthrough of how it actually works.
• ivorpad/mercadona-cli: An unofficial single-binary Go CLI to search the catalog, read prices, build a cart, and check out from Spain’s Mercadona supermarket, with structured JSON output for scripting.

SDR, Hardware & Misc

• The Xteink X4 E-Ink Reader: A hands-on with the Xteink X4, a £40 e-ink reader small enough to stick to the back of a phone.
• ATS MiniRadio with RTTY, CW, WeFax, SSTV: A modification for SI4732 ATS MiniRadios (V1 to V4B) to decode SSTV and WeFax picture transmissions.
• Unlag Neo: Macbook Neo Cursor lag “fix”: A gist with a workaround for the cursor lag on the MacBook Neo.
