Hi. In this gist I'd like to share a solution for connecting a Windows laptop to a Macbook into LAN via a 5$ usb-c cable (you can ping from either to either, and, for example, connect from one to another in team viewer via LAN IP). This solution was produced by Claude Code after 2 days of trial and error. Supposedly, you should be able to make a prompt to Claude Code to use this file to set up the usb-c LAN connection and it will hopefully implement the solution much faster than it did for me.

On the Macbook side I did not have to do much, just enabled Internet Sharing with Wi-Fi as source and ticked all other checkboxes for the destinations.

LLM Wiki v2

A pattern for building personal knowledge bases using LLMs. Extended with lessons from building agentmemory 20K+ Stars ⭐️, a persistent memory engine for AI coding agents.

This builds on Andrej Karpathy's original LLM Wiki idea file. Everything in the original still applies. This document adds what we learned running the pattern in production: what breaks at scale, what's missing, and what separates a wiki that stays useful from one that rots.

What the original gets right

The core insight is correct: stop re-deriving, start compiling. RAG retrieves and forgets. A wiki accumulates and compounds. The three-layer architecture (raw sources, wiki, schema) works. The operations (ingest, query, lint) cover the basics. If you haven't read the original, start there.

Running OpenCode with Gemma 4 26B on macOS (via llama.cpp)

As of April 2026, Gemma 4 tool calling is broken in Ollama v0.20.0 (ollama/ollama#15241) - the tool call parser fails and streaming drops tool calls entirely. OpenCode also has issues with local OpenAI-compatible providers (anomalyco/opencode#20669, #20719).

This guide documents a working setup using:

llama.cpp (built from source with PR #21326 template fix + PR #21343 tokenizer fix) instead of Ollama
OpenCode built from source with PR #16531 tool-call compatibility layer

Tested on macOS Apple Silicon (M1 Max, 32GB) on April 2, 2026.

Check recent system journal entries for "hang detected" message(s), and if found then reset network interface.

Workaround until driver / kernel fixed.

TLDR; Quick start

Copy attached script to somewhere, e.g. /root/cron/hangcheck2.sh
If your interface name is not eno1 then update the ifup and ifdown commands
Review code for your peace of mind (after all, this script is going to be running as root!)
Give it a test run:

Minisforum MS-01 Barebones

I was looking for mini PCs with SFP+ and found a lot of fairly expensive small servers that were tempting. Then I got lucky and saw a new product coming out from minisforum, the MS-01, which had everything I needed at a much lower pricepoint.

I went with the 20 core intel i9-13900H but I think any of the three would have been fine for my needs.

Fixing device UUIDs in BCD under Linux

Please note, it's easier to just use a recovery flash drive/dvd disk!

I just wanted a new challenge, and I found it:

Info on target system

My friend has switched from Windows to Fedora. Somehow in the process, Windows Bootloader went missing from EFI partition (I would love to know how did that happen as much as you do or don't, but I wasn't supervising at the moment, so... no idea)

Enable IPv6 OSPF Routing on Thunderbolt-Net Mesh

This requires proxmox kernel 6.2.16-14-pve or higher due to bugs in earlier version.s

This will result in a routable mesh network that can survive any one node failure or any one cable failure. Alls the steps in this section must be performed on each node
