RFC 9842 — Compression Dictionary Transport, published September 2025 — lets HTTP clients and servers negotiate a shared compression dictionary, then compress responses against it (dcb for Brotli, dcz for Zstandard).

rocksdbffm, the FFM-based RocksDB binding I wrote about last time.

I needed Zstandard compression for vortex-java, a pure-Java implementation of the Vortex columnar format I've been building.

Recently I built three small Java libraries using JDK 25 and the Foreign Function & Memory API: rocksdbffm, vortex-java, and zstd-ffm.

Once in a while, someone shares an "X rules of software engineering" list and I find myself agreeing with about a third of it.

Your Compiler Is Already Part of Your Security Team made the case for domain primitives: encode constraints in types, the compiler enforces them forever.

In 2004, I wrote a packet sniffer called pangolin.

The best way I know to learn something is to build something real with it.

I've been experimenting with Claude Code on my side project hosh, an experimental shell written in Java.

Today I pushed a commit to hosh.
