How does oxlint compare to alternatives like biome? Is it similar to Rome's original vision before all the investor shenanigans?

An image of a SQL text which has filtering clauses decorated based on how, if at all, the database used the index when processing the query

An image of a SQL text which has filtering clauses decorated based on how, if at all, the database used the index when processing the query

An image showing the visualization of a query and the `Index Scan` stage used to execute it. The index is on the `game` column, so it gets a green underline. The `date` column is NOT indexed so the database must retrieve and process records in order to apply that condition. That earns the associated text in the WHERE clause a red squiggly underline

Can the code underlining approach used by IDEs be applied to show indexing problems directly on SQL text? @simp.engineer thinks so!

See how his latest work magically surfaces scan type details from query execution on the relevant clauses in the query itself: app.querydoctor.com/ixr/share/w3...

What better first post than to announce a feature? How the DB handles the WHERE clause of a query is now shown directly in the diagrams! Easily see how the logic of SQL is translated into a plan the DB can use to find the results.

Check it out an example here: app.querydoctor.com/ixr/share/QQ...

That's such a heartless response man. This is about parents realizing they can trust their kid to behave when their hands are tied. I'm sure children aren't struggling with literacy because they watch videos to pass the time while their parents are stuck in meetings

We initially didn't even realize we were building a database to do these visualizations from scratch @querydoctor.com about a year ago until we ran into PGlite, and realized we could leverage Postgres instead! It's been a huge game changer.

Anyone else experiencing this bug with their Spotify wrapped? It instantly skips past every slide and goes to the last screen. A restart won't fix it either. I know I have the most cursed combination of top artists, don't even get me started... (seizure warning)

An unordered / non-exhaustive list of things that helped scale Bluesky's infra efficiently:

+ Exiting the cloud (colocation)
+ HAProxy w/many Node backends
+ Go w/clever code
+ ScyllaDB
+ SQLite w/per user databases
+ Redis w/many instances
+ AMD servers w/many cores
+ Purchasing bandwidth directly

As a Turk, if I don't call Ivory Coast "Cote D'Ivoire," I don't see why anyone else would want to call Turkey "TΓΌrkiye"

Security pro tip: if you find a USB key on the ground somewhere, DO NOT plug it in to your home computer.

Take it to the office and plug it in there. They have way better software that will mitigate any threats.
