The book that @sarna.dev and I co-authored on writing engineering blog posts is now published. And it’s flanked by the best imaginable “bookends”: a foreword by @bcantrill.bsky.social and an afterword by @scott.hanselman.com! Details and Amazon/Manning links at bit.ly/3AVPWn9.
A nice recap of @clickhouse.com's P99 CONF keynote, by Joab Jackson of @thenewstack.io thenewstack.io/moving-from-...
