Hermes dual-booted a Windows install that was doing nothing, while its Ubuntu root sat at 86% full. Deleting Windows was the easy part. Giving the space to Ubuntu was harder: it was on the wrong side of the root partition. This is how I moved a live root filesystem without going near the machine, and what made the remote reboots safe.

This site has a light and a dark theme, and the cover image cross-fades between them — so every illustrated cover needs a genuine night twin. Faking one by dimming the day image is easy and looks wrong. Here's how the covers get generated, and the three gates — two of them running on a GPU — that prove a dark cover is a real re-light and not a graded fake.

Two weeks ago I said the DGX Spark's bandwidth wall was physics, not a driver update — fast or big, pick one. Then I ran a 122B model on the same box at six times the speed of a 70B. The law was right. The number I kept feeding it wasn't.

I bought Andromeda, a DGX Spark, to fine-tune models — but first I owed my last post a rematch. I re-ran the same local/free/paid LLM inference benchmark on 120 GB of Grace-Blackwell instead of a CPU NUC. It fixes the one thing the NUC got fatally wrong, hits a bandwidth ceiling I didn't see coming, and makes clear why the real reason I bought it isn't inference at all.
