it’s incredible watching people justify how llms are bad at the thing they’re really good at, but good at everything else

Back in the day on Twitter some NFT shill announced they'd lost TONS of money on their silly little ponzi scheme so I whacked this up as a reply and boy did it do numbers

Depending what you want to receive on it, A&A's numbers can be quite useful. They have an SMS -> email gateway (receive only I think, but that's good enough if you just need to receive auth codes).

genuinely depressing how many technical blogs are now littered with the hallmarks of samey, sloppy, llm-generated writing

still can’t believe how quickly people have been willing to shed their own voice for this

According to all known laws of aviation, there is no way a bee should be able to fly.
Its wings are too small to get its fat little body off the ground.
The bee, of course, flies anyway because bees don't care what humans think is impossible. #glassart

TIL Postgres 18 enables page checksums by default.

Glad to see it’s happened. Feels like it’s been part of the standard advice for a long time now.

Screenshot of my Slack profile page. I'm trying to add the Anthropic magic string that makes the Claude LLM refuse to answer to the end of my name. It doesn't fit in the 80 character limit.

Introducing pg_strict for Postgres.

Our new extension adds a safety net to Postgres, catching dangerous queries before they run.

Tuning your database just right can be counter-intuitive, unless you understand all levels of the system.

Intuitively, most would say "more work_mem = better" for building indexes, but this hurts performance due to L3 cache behavior.

Great article by Tomas Vondra.

TLDR: io_uring won't help much if treated as a drop-in replacement for existing database I/O architectures. Better performance will often require architectural changes. When applied, there's tons of performance gains to be had.

Here's the paper: arxiv.org/pdf/2512.04859

I'm excited about the database performance io_uring will unlock.

Last year I benchmarked Postgres 17 vs 18 to test the initial io_uring upgrades. I was surprised to see they weren't always a clear win for TPC-C.

This paper studies the potential, and the future looks good.
