This post is locked and it calls out my tweet so i will respond here. This issue is nothing like the one we are facing. we have capacity issues getting huge metal nodes for customers that order them in batches of 750 at a time. Supabase isn't able to provision small nodes. We can…

I don't think people realize that companies Block (Cash App), Intercom, Cursor, Whop, MyFitnessPal, Kick run their largest databases ON OUR CLOUD. This is a massive responsibility that we take very seriously. It's also incredibly different from selling on prem software.

After a discussion on the public postgres slack, I POC'd a simple function that returns key parts of a SQL and avoids leaking literals - an alternative to full parsing (eg. PgAnalyze). The aim is to share query intent without exposing sensitive data. ardentperf.com/2025/10/15/san…

Today's video is a SQL tip! Are you seeing the ORA-00918 error at random times? Here is the likely cause, and just like in most cases, it all comes back to same reason as always :-) youtu.be/VErx5k-H4J8

eBPF is like a runtime-programmable OS running within your OS. The tracing, security, network data path ops tools are just some types of apps built on top of that programmable OS (with x-ray vision to everything that's going on).

📖 Your Weekend Read: @P99CONF is the premier place to learn how engineers are pushing eBPF to its limits. We look back and preview upcoming talks from @jrfernandez, Liz Rice, @tanelpoder, @andy_pavlo, @parttimen3rd, & @ddelnano. ow.ly/ncjn50X64zy #ScyllaDB #P99CONF
