this project stores millions of text chunks inside a video file (mp4)

then runs sub-second semantic search on it
- no vector DB, no servers
- uses 10x less RAM & storage
- no internet required

it's called Memvid and it just broke my brain

Happy anniversary to @MySQL (yesterday this page turned 20y) l: https://bugs.mysql.com/bug.php?id=11472

I’m surprised Neon was up when they ran these benchmarks.

Quoting PlanetScale (@PlanetScale)

PlanetScale is the fastest Postgres provider. See how we stack up in benchmarks:

🚀 @FireboltHQ just announced Firebolt core – the same distributed query engine behind Firebolt, but now available as a free self-hosted version

All you need to do is run a single docker command

And it’s amazingly fast!

Check it out!

This is a follow up to my previous posts. When SQLite encounters checksum failures in WAL, instead of raising an error, it drops all subsequent frames; even if they are not…

Postgres 18 will be out later this month. The biggest news is asynchronous I/O which will be turned on by default for clusters and expected to mean read performance gains for everyone. More features and details in our blog ⬇️

This blog lets you test the RETURNING clause with updates in PostgreSQL 18, and allows you to have a look at practical scenario.

TIL SQLite will just let you name a column `rowid`, and it will just be a regular column (no unique constraint).. you then lose the ability to explicitly change/update the actual rowid (in the case you don't have a rowid alias/PK)
