Mostly because MySQL development is slower.

It is also a bit tricky tradeoff. You do not want to be stuck with the same data format forever. So databases like MySQL and PostgreSQL need a downtime when doing a major version upgrade. They both try to keep it short, usually seconds, but minutes can happen in either database.

Yes. But for most workloads it is not much for PostgreSQL. You often will not have to shard at all.

Exactly, MySQL and PostgreSQL are the same here. Maybe one is a bit faster than the other at doing major version upgrades but the behaviours are quite similar.

I have not ran MySQL for some years but it at least used to have exactly the same issue. Upgrading a database with MySQL can take a long time if you have many tables. The main difference is only really that PostgreSQL does it with a separate tool, pg_upgrade, while MySQL does it as part of the main binary.

For both MySQL and PostgreSQL you will need to use some kind of logical upgrades if you want no downtime.

Sorry, I was unclear. With that I did not talk about this particular deal. This particular deal seems sane. XAI built more compute that they can use themselves since Grok is not very successful so to not just have the hardware standing there they rent it out to competitors. Makes total sense.

It is other things Musk has gone with Twitter and SpaceX which are shady.

If your dad had owned an emerald mine I am sure you could also have been that dumb.

But to be more serious: It is impossible to say if this is good or bad for XAI without more numbers. What if they bought their compute way over market price and sell it at a loss?

No, CoreWeave for example also rent compute to the big AI companies. This likely just means Grok has few users so they need to rent their extra capacity to their competitors.

Their satellite internet business is the only thing which makes them money, which is enabled by their orbital launch business which is as of right now not profitable and I have no idea of if it ever will be but without it they would not be able to launch enough satellites.

Their stupidity with AI and buying X mostly seems to be about scamming investors to make Musk even richer. Like this particular deal is just them doing what CoreWeave does at a SpaceX valuation.

Yeah, I am employed by an open source company (to be clear not open core) and most of the external code contributions we get are a net cost for us. It takes more time to review than it would have taken for our team to code and review.

The real value we get from being open source is high quality bug reports and trust from our customers, not the external contributions. The only reason we welcome external contributors is marketing and generally being welcoming. If LLMs make this cost even higher for us then we might have to stop accepting external PRs.

Yeah, they are essentially praising price dumping.

> But apparently trying to distinguish those from the 'one-shot' vibe coded PRs is too much work for the Ladybird team.

Yes, that is exactly what this announcement is about. That it was too much work for them to tell those two apart.

I do and I agree with him. Iran is just one of many on a long list of supporters of terrorism which includes the US, the UK and Israel, plus many more countries like Turkey and Russia.

I think you are underestimating these grass roots groups. Some of them are supported by foreign inyerests who want to undermine trust in the government.

There was recently in Swedish media an article about harassment of Jews in Sweden and the guy they talked to was a member of a Zionist organisation who advocates for that Jews should move to Israel. It is fine to interview him, but such a clear conflict of interest should have been disclosed.

The main innovation here seems to be compile time checking of that foreign keys are respected but that is a thing that can be added to SQL and there is at least one proposal for doing so. So I do not really see anything fundamentally different from SQL.

Full disclosure: I am one of the co-authors of this paper and an associated patch implenting it in PostgreSQL that we have proposed.

I am happy to see more people than us think this is useful.
