Has `parallel` always been this simple to use? Why did I stop using it then??

Accidentally removed an Iceberg table on S3. Luckily, just a drop in the bucket.

I mean ... I have 8 on this list; I just haven't traveled to those places.
Still think your statement likely holds true though

Misunderstood how the framework was doing upserts. It didn't work with compound PK. Overwrote a lot of important data with random UUIDs.

Runtime-Extensible SQL Parsers Using PEG Despite their central role in processing queries, parsers have not received any noticeable attention in the data systems space. State-of-the art systems are content with ancient old parser generators....

New blog post by @hannes.muehleisen.org and @markraasveldt.bsky.social:

Runtime-Extensible SQL Parsers Using PEG
duckdb.org/2024/11/22/r...

This post discusses how parsers in DBMSs could be re-designed using Parser Expression Grammars for extensibility and improved error reporting.

Curious how much harder that last step is made by the fact you don't know the code much yet as well as if you'd written it.
Does it erase 10% of the gains you made by using ai? Or 100%? Or worse... 130% and you end up slower overall...

Give the sharpie to your kids and tell them to write whatever they want on the boxes if you dare... And we'll if you have kids I guess.

I went to the "small data conference" earlier this year and this is basically what I heard over and over again.
I think the ceo of fivetran said most people who have big data should enable streaming data capture instead of doing a full snapshot each time! OUCH!

Advent of Code 2024

So adventofcode.com Advent of Code starts today / tomorrow what language is everyone using this year?
I ... might do Kotlin because that's the work thing now and at least that'd be a fun way to learn.
