Porting Gemma 4 E2B to SGLang-JAX on One Cloud TPU v5e
SGLang-JAX serves the Gemma 4 31B and 26B A4B on TPU and fails to load E2B. A two-file patch adds per-layer embeddings, shared K/V and the double-wide MLP; on one flex-start v5e-1 it then serves 159.9 tokens per second for one request and 4,249.4 at 64, 2.52x vLLM, with GSM8K level with the bf16 JAX engine.
Six Serving Engines on One Cloud TPU v5e Chip: Gemma 4 E2B
vLLM, SGLang-JAX, a pure-JAX engine, a Rust model over PJRT, and TorchTPU in Python and Rust serve Gemma 4 E2B on one flex-start v5e-1, with the same prompts, the same 1-to-64-request sweep and the same GSM8K questions. vLLM is the engine that serves out of the box; SGLang-JAX with an E2B patch is the fastest at every load from 8 requests up.
Why Developer Experience (DX) Isn't Enough in 2026: You Need Agent Experience (AX)

NetBSD 11 desktop on a Raspberry Pi 4
Now that I moved this capsule to a VPS, my Raspberry Pi became available for other use. NetBSD is the only open-source operating system in development that I know of, that doesn’t include AI slop. At least for now? I decided to give it a go and try to install it on the Pi. How hard can it be? It turns out, not that much. I made a small guide on how I did it, maybe it helps someone.
