With the next product launch season fast approaching, a reminder of the first question you should *always* be asking when a figure of merit is presented without context: #HPC

Big Data on the Move: Can a Framework Laptop 13 ultrabook run terabyte-sized workloads with DuckDB? @szarnyasg.org ran the experiments and shared his finding in our latest blog post: duckdb.org/2025/09/08/d...

As someone who has exclusively used Rust, Go and C++ for the past 8+ years I find the JVM stack (lots of Java & Scala) a breadth of fresh air from a tooling and productivity perspective.

I think I have finally managed to articulate this very fundamental but slightly counterintuitive fact about how shell redirection works

Stopped once I hit the 18 seconds total runtime, code is available here github.com/clflushopt/s... might take this for another tour, still lots of tricks to pull (custom hashtable for the joins, morsel driven parallelism...)

My work on SIGMOD 2025 (unregistered) continues my implementation now runs in 24 seconds instead of 11 minutes on my hardware (Ryzen 9 9950x), next goal is sub 10s. I will write a blog post about this, since I was led down some dangerous paths hint blog.llvm.org/2011/05/what... #SIGMOD2025

I am not having fun trying to reverse engineer and implement the TUM's db group paper on hash tables for join processing db.in.tum.de/~birler/pape...

@apachedatafusion.bsky.social supports a fully extensible range of user defined window functions as well as scalar, aggregate and table functions. Aditya Singh Rathore's new blog has more: datafusion.apache.org/blog/2025/04...

A great question -- and one that I used as a foundation for an entire talk speakerdeck.com/bcantrill/th...

can I code fast? no. but can I code well? also no. but does my code work? alas, no
