IntelliJ integrated debugger & profiler that just works, VisualVM, jmh + jcstress + jol.

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.

Hatchet Deploy More Resilient Apps. Hatchet is a platform for building distributed web apps that solves scaling problems like concurrency, fairness, and rate limiting. Instead of managing your own task queue ...

Would Hatchet hatchet.run & River riverqueue.com fit in the queue subsection ? Both are transactional "job" queues built on Postgres.

when you redirect, the shell opens the file BEFORE the program starts sudo echo blah > file.txt first I'll open file.txt... THEN I'll run sudo echo blah this is why file.txt isn't opened as root!

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...)

Congratulations on the GA release but I can't find any information about pricing, those tokens tend to be expensive.

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...

I've been sharing this at $work and trying to get people to write debugging tooling as well ! I learned a lot from it personally.

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
