Field Guides

Every guide here follows one rule: commands you can run, versions you can trust, and an honest status on every page. verified means the commands were executed in the stated environment; untested and draft pages say so, out loud, before you rely on them.

brewing

Teapresso

Pull a concentrated tea shot through your espresso machine: machine requirements, the physics that break shots, the procedure, and cheaper alternatives.

Any pump espresso machine with a single-wall portafilter basket + loose-leaf tea. Procedure NOT executed on the build box (no espresso machine); compiled from cited sources, verified against each other.untested

cuda

CUDA Streams

Overlap memory transfers with kernel execution: streams, async memcpy, pinned memory, events, and a benchmarked pipeline.

Linux, CUDA Toolkit 13.2 (nvcc 13.2.86), compiled -arch=sm_80. All code COMPILED with nvcc 13.2; NOT EXECUTED — no NVIDIA GPU on the build box or deploy host. Semantics verified against CUDA 12.8/13.2 official docs and headers.untested
