This was an extraordinary day. 57 commits across three projects, +42K net lines. The headline: an entire SMB2/3 client library built from scratch — 40 commits, 38K+ lines, going from initial scaffold to a crate that benchmarks faster than native macOS SMB on every operation. That's phases 1 through 8 of the protocol implementation, NTLM auth, three signing algorithms, compound requests, pipelined I/O, streaming downloads, file watching, CI, real-world benchmarks against two NAS devices, and polished public API with examples. In a single day.
On top of that, Cmdr v0.10.0 shipped, two mtp-rs releases were published, several real bugs got fixed (MTP move silently overwriting, watcher cache invalidation), 13+ E2E tests were written, a11y contrast issues were fixed, and Docker tooling was improved.
The flow pattern is striking: Cmdr fixes in the morning, smb2 kicked off at ~15:00, a 30-min call at 16:30, then an unbroken 12-hour coding streak on smb2 until 4:41am — weaving in Cmdr releases and mtp-rs work during natural pause points. Deep focus to an almost alarming degree.
The download numbers are encouraging: half the downloads are already v0.10.0, meaning the update mechanism is working and people are staying current. UK showing 41% of downloads is a concentration worth watching.
Honest note: the 5am finish is a pattern to be mindful of. The output is undeniably impressive, but sustainability matters when building a product solo. The quality of the smb2 work (security fixes, real-device testing, benchmark methodology) shows it wasn't sloppy late-night code — but still.
