I had such a great time speaking at my first #FOSDEM. Check out the other great talks by some of my colleagues!

I've uploaded my slides, can find the link at the bottom of the description page now: pretalx.fosdem.org/fosdem-2026/...

Thanks! I need to upload them still, I'll be sure to do that tomorrow

Heading to FOSDEM!

Very excited for this year's #FOSDEM! Lots of talks by Polar Signals folks:

Out of curiosity which bindings didn't work?

Zed was the first editor other than vim in 15 years that's worked for me and I didn't find anything missing

They hate us so much but we love each other more

My daughter's school in Richfield, MN (adjacent to Minneapolis) is closing tomorrow due of out-of-control federal agents. Fourth graders spent the week building walls of snow at recess to protect their classmates from ICE. This isn't about immigration enforcement, it's about terror.

My EuroRust talk has been uploaded to YT! I cover how we architected our Rust database at @polarsignals.com as a set of state machines to enable deterministic simulation testing and catch hard-to-reproduce bugs before they hit prod.

I wonder with the increase in llms doing coding/architecture if we'll see an increase in interviews being code review

If Costco sponsored a stadium would the hotdogs there be $1.50?

performance[vortex-array]: don't call is_valid to count bytes in varbinview by asubiotto · Pull Request #5814 · vortex-data/vortex I noticed that the better blocks compressor uses count_referenced_bytes which calls is_valid on each view and results in an expensive scalar_at call. This was 30% of our system-wide CPU usage over ...

A simple 50-line code change saves us 30% of CPU across our whole infrastructure. This is the magic of system-wide profiling with @polarsignals.com. Easy to spot, easy to fix.
