Unfortunately, I won't be joining #FOSDEM.
I got sick late last week and decided not to contribute to FOSDEM flu and canceled my trip.
Have fun everyone! Next conference!
Let's scale Pyrra even further!
Imagine not having continuous profiling and sleeping on this. Wild.
Happy to share that I've been nominated to the Vortex Technical Steering Committee! It's been fun and productive switching to Vortex from Parquet as our storage format @polarsignals.com and I'm excited to continue contributing to the Vortex project.

Next.js 16 + turbopack took our frontend builds from 5-7m down to just over 2m. This means faster speed of iteration in development and faster CI.
Performance is UX. Performance is DX. Performance is a feature.
Are USDTs the key to unlock the future of low level tracing? Maybe! Read all about how we implemented them and how we plan on using them to breath new life into observability! www.polarsignals.com/blog/posts/2...
It does now.
Standing on the shoulders of giants. We built our new database on open source projects.
We completed a major project to switch our storage file format from Parquet to Vortex 🌪️ resulting in 70% average query performance improvement across the board 🚀
Learn more about how rethinking interface-imposed limitations unlocked these gains in our latest blog post 👇
"Stell dir vor du installierst nix."
Germans talking about installing NixOS is very funny. 😀
Ever wanted to filter flame graphs by distributed trace ID? Or by anything else? In Node.js, now you can! www.polarsignals.com/blog/posts/2...
Happy Profiling! 🚀🐻❄️
😭
Was digging into JS source maps recently and had a lot of fun writing this post, especially the interactive bits. 🤓
We made a bit of a dumb thing early on at Polar Signals where we accidentally created a critical GCS bucket as multi-region. But today I learned about Bucket relocation (launched in 2024). Very timely! docs.cloud.google.com/storage/docs...
Congrats! Exciting!
That soundtrack is so incredible. Iconic.
Previously, we've correlated GPU metrics with CPU profiles, now we can actually show you GPU time!
This is suuuuuper exciting! 🚀
Pyrra v0.9 is here! 🎉
github.com/pyrra-dev/py...
It's incredible to see the amount of diverse contributions to the project!
I didn't even realize it was that way until the release was published! Incredible to see!
Thank you, everyone!
Native Histogram considered stable in @Prometheus.io going forward! 🥳
Props to all the people who worked on this for years!
This talk is rage baiting me hard. 😂
#PromCon
BER 🚄 MUC
Oh my way to #PromCon!
Excited to meet with the @prometheus.io community again!
See you tomorrow!
Which theaters play the NIN soundtrack only? Cause I would still to listen to that in full blast.
Took advantage of the lunch break to replay this great talk by Alfonso Subiotto (@asubiotto.com) making the case for a State Machines based approach to Deterministic Simulation Testing, being used at @polarsignals.com, very interesting!
Their inspiration for this: sled.rs/simulation
It's amazing to see a packed room for the talk of our very own @asubiotto.com, who is talking about Deterministic Simulation Testing at @eurorust.eu right now! 🦀 ⌛
We're having a blast at @eurorust.eu today! 🦀
Come by to talk about all things performance and continuous profiling!
