400 days of Go
It's been 418 days since my first Github commit of Go code. In that time I've written a Syslog-to-Kafka producer, a Raft-based distributed SQLite database, a near real-time log search system, and become a core developer of InfluxDB. So if there is one word to summarize Go, it's productive. I haven't had the same burst…

Debugging Lisp, Part 5
This post is for all of the miscellaneous features that arent large enough to get their own individual posts. If you havent read all of them, here are the links to the previous posts on recompilation, inspection, class redefinition, and restarts. One somewhat obscure tool for debugging is SBCLs trace.

The compiler flag that time forgot

Redundancy vs. dependencies: which is worse? (2008)
I think that all other considerations are of the extrinsic real-world kind – domain modeling, usability, schedules, platforms, etc. I also think that I can show how any "good" programming practice is mainly aimed at minimizing redundancy, dependencies, or both. I even think that you can tell a "good" programmer from a…

LALRPOP, an LR(1) parser generator for Rust
Around four years ago, when I had first decided to start at Mozilla research, I had planned to write an LR(1) parser generator. It seemed like a good way to get to know Rust. However, I found that newborns actually occupy somewhat more time than anticipated (read: I was lucky to squeeze in a shower), and hence that…
