The Missing Semester of your CS education [MIT IAP 2026] - https://missing.csail.mit.edu

In January, @anishathalye.bsky.social, @josejg.bsky.social, and I returned to @csail.mit.edu to teach Missing Semester, a class on topics we miss from most CS programs—tools and techniques that everyone should know, like Bash, Git, CI, and AI tools. Today, we’re releasing the course for free online!

MSc thesis work of Emil Houlborg and Andreas Tietgen @itu.dk will be presented at CIDR conference next week. Huge congrats to them!
Modern storage I/O landscape is very diverse, yet not so accessible. We created a new file system extension for @duckdb.org with xNVMe to help with this accessibility.

Azim had a stellar committee which included Daniel Lemire (TELUQ 🇨🇦), Pinar Tözün (ITU 🇩🇰) and Viktor Leis (TUM 🇩🇪).

They gave talks at the Dutch Seminar on Data Systems Design (DSDSD) on SIMD-accelerated parsing, xNVMe and escaping from the insanity of SQL.

Thanks for the interest @jauntywk.bsky.social! We created a new filesystem extension for DuckDB that integrates xNVMe. Original goal was to make it easier to test flexible data placement SSDs, but xNVMe gives a lot more. More details are at vldb.org/cidrdb/paper...

One year together as the Data, Systems, & Robotics section. Very happy to be part of this group. Our first section outing was on Tuesday with talks covering topics of medical imaging, robotics, internet-of-things, and data systems. Plus, a pub-quiz that required a lot of math to answer questions! 🎉
