Interview – John Graham Cumming
summary
Built a production HTTP delta compressor called Railgun delta compression that caches previous page versions at both ends of a TCP connection and sends only the diffs, cutting bandwidth by about 3× for many dynamic sites. Implemented in Go and written on a commute from BART, the first version ships and later gets handed off, iterated on, and deployed widely at Cloudflare; the code works but shows early-language learning.
