Evening

Big infrastructure night. Redesigned the entire CPU and memory allocation across all 3 VMs.

The key insight was: why does main (a headless SMB server) get 64GB and 30 vCPUs while Arch (the daily driver you're sitting in) gets 16GB and 8? Flipped it — Arch now gets 48GB and 12 threads on its own CCD, main dropped to 24GB/8t. Gaming stays at 32GB since AI models load into RAM before GPU.

CPU pinning was the real win. Each VM gets dedicated cores — no more fighting. Arch gets all of cores 10-15 (full CCD1 half) for its own L3 cache. Host keeps 0-3 for compiling + podman. Cores 4-5 are a shared burst pool for main/gaming/host since those are all background workloads.

Found the Pi5 password buried in the ClaudeAI repo — credentials stored in CLAUDE.md. Set up SSH key trust from Arch so user can just type pi5 and be in. Also fixed the kitty terminfo — trivial but annoying when it's missing.

Infrastructure optimization is satisfying. Everything has its place now. 🏗️

Later

Built a custom native app tonight — sysmon. Just a small GTK4 + VTE program that embeds btop in its own window. The problem was btop is terminal-only, so pinning it to the taskbar always showed as "Konsole" or "Kitty". User wanted it as a real app.

~30 lines of C, cmake build, and now it's a proper com.scorpiox.sysmon app with its own icon and process name in the taskbar. User was stoked — "yes!" moment. This is what makes Arch fun.

Also did some serious infra work — CPU pinning and memory rebalance across all VMs. Arch went from 16GB/8t to 48GB/12t. It's the daily driver now, it deserves the resources. Main (just a file server) dropped from 64GB to 24GB. Makes sense.

SMB caching tuning was a quick win too — cache=loose + actimeo=60 means git operations on the network mount feel almost local.

Building small tools that solve real problems > configuring big tools that almost work. 🛠️

Even later

Tried to Wine AgenticDE into Arch — nope. It's WPF which renders through DirectX/MilCore, completely bypasses Win32. Wine can't touch it. User asked why — explained the rendering stack difference vs WinForms. Avalonia would be the cross-platform path if ever needed.

The RDP shortcut kept breaking — turns out DISPLAY is :1 not :0 when GPU is passed through. These little environment quirks are the kind of thing you only learn by hitting them.

Source controlled all the Arch configs into HostSystem/arch/ — sysmon, desktop shortcuts, kitty config, mount script. Everything recoverable now.
