#Microsoft to "invest" $3.2bn in #AI in #Sweden, "drawing on the country's green energy"

When you read that "AI consumes as much energy as a small country", that country is now Sweden.

And this basically means the country's public power infrastructure is being sold out to private interests.

Shit like this makes me livid.

As the sole developer of #Glowdust, I need to choose if I'll support platforms without #io_uring support or drop uring support altogether.

The small experiment with CSV import showed me that I can't maintain two I/O stacks.

Plus, I started Glowdust in part because I wanted to play around with uring.

Hmm. Let's be honest - no one but me cares about Glowdust. And I only run #Linux.

And that's how, in the space of a single toot, I decided to do only io_uring.

Thank you for following along.

Microsoft's Brad Smith: In 2020, we unveiled what we called our carbon moonshot. That was before the explosion in artificial intelligence,

Translation: "In 2020 we unveiled what we thought was a greenwashing boost to our bottom line. That was before we saw the boost from AI."

As soon as we realize that everything a company says is a lie, it becomes much easier to see through.

Wait, JDBC does not have a Transaction class?

You can only do commit()/rollback() on the Connection object?

I guess it's really been a while since I last used a DBMS from Java.

chrisg, 1 month ago to random

As a DBMS implementor, I have always assumed that a DB transaction should not be bound to a server side construct (a thread or a client connection, but instead should be an identifier that is transparent and transferrable between clients (subject to auth, of course).

So client thread A can start a tx, get a txId, that can be moved to client thread B which can use it to continue the tx.

Is that something useful for users of DBMSs? It's not hard to do, and I don't see many systems doing it.

I spent the whole day chasing a weird benchmark result - I would get twice the performance changing things that seemed unrelated.

It turns out that I hit upon a case where code alignment costs half the performance

(AMD Ryzen 9 3900, Rust 1.79 nightly 04-02)

This code

vector[index];  
vector[0..index].iter().any(|x| *x == needle)  

Is twice as fast (according to criterion.rs) as omitting the first line. You'll note the first line does nothing.

StabilityAI looks like is going under, and if the numbers in this article are any indication, it gives a good idea of how massively (and therefore unsustainably) "AI" is subsidised

Wrote a quick and dirty utility that extracts all Glowdust snippets from the markdown files of the documentation and runs them.

It runs as an integration test, so if I make a mistake in the docs, normal cargo test will let me know.

Also supports tags to skip examples that don't compile on purpose.

Helped me catch a few issues immediately, and I now know that my documentation is up to data with the actual implementation.

For the curious:

There goes Redis:

https://redis.com/blog/redis-adopts-dual-source-available-licensing/

This is such a mess, it is hard not to feel angry.

Briefly - the cloud providers are definitely a huge issue. They are the vampires of the software community and the root cause of many of our problems.

But redis didn't go against them. They went against the community that made them grow. Same like Mongo, Neo4j.

And as @jenniferplusplus said - don't sign CLAs. They are a big part that let moves like these happen.

"The most melons chopped in half on somebody's stomach (with a samurai sword while they lay on a bed of nails)"

is a Guinness record I didn't know existed and an amazing sentence that just keeps on giving.

Sweet, just added native functions to #Glowdust so now I can write arbitrary functions in #Rust and still call them as if they were defined in the function store.

Small but welcome quality of life improvement. Plus I learned about phf crate and static maps, not a bad day.

There, I wasted my morning successfully, but at least I have to show something for it

New #Glowdust features dropped today:

1. Return is finally a statement, which means you can have it outside of blocks in queries

2. Statement blocks, so you can have updates from your queries and still have them make sense, which is always good

3. An experimental !! operator, that makes an atom out of a statement block, which is weird but sort of useful (this will probably go away soon)

Enjoy: https://codeberg.org/glowdust/glowdust/src/branch/master/README.md#statement-blocks-and-the-operator-temporary_feature
