Willkommenkultur should have given it away that I am talking about refugees. however, in normal societal culture, these cannot be separated, I promise you. refugees set the tone for how migrants are viewed by the general public.

that was such a self inflicted wound that Europe, and Germany, did to itself. No wonder people are voting AfD.

and for the downvoters: these are facts. this is what the politician in Europe campaigned with, built platforms on and said for everything. "We'll get engineers, and doctors! Lots of workers!" Fast forward 5 years... How's the Willkommenkultur going you ask? Look at AfD. Look recently at the 10 million Switzerland votes.

And I'm writing this as an immigrant myself... It's sad.

700 EUR doesn't seem like expensive for what it is.

Every large enterprise?

Who do you think pays for your subscription's actual usage?

Copy and paste...? In mid-2026? Why on earth would you copy and paste code instead of having the cli tool to the coding end to end?

I haven't opened an IDE in 8 months or so and have no plans to go back.

because they are making an extra step: instead of the snapshot being actually an object manifest, they store the snapshot metadata in a relation database.

I have a use case where we do 100k changes a second. I bet you "their unlimited snapshots because we are cool and using dbs for metadata" will fail in such a use case.

when people talk about S3 they mostly mean AWS, but I do agree S3 is a standard interface. in non-AWS cases they'd say S3-compatible.

they exist, sure. And I'm sure it can handle PB+. on prem is an existing market, however, if you reread my comment I talked about running minio on AWS because S3 is too expensive - just doesn't make sense to do.

I've yet to met a Fortune 100 who isn't mostly using either on prem or a large hyperscaler (S3/Azure/GCS).

up to a limited number of snapshots. it's not arbitrary times, it's when there was an atomic snapshot created in the catalog.

your reply makes zero sense.

there is a reason why people develop for S3: a lot of enterprise data is there. people ingest there from various sources. and it's not just parquet usually, it's multivendor sources writing to an iceberg catalog.

nobody will run minio on AWS other than hobby projects and small demos.

I regularly work with iceberg datasets in the double digit TB range per dataset. keep that in mind when you think about sizes. databricks, snowflake, large enterprise vendors: they are targeting these sizes.

I disagree. I think it's very important to see how can those papers be turned into real things. Rejecting something for too practical is a joke, and if I ever find out who gave us that review, I'll have a talk with them.

I can e-mail wise now with my bill and pay it. it's AWESOME. I've used a bill that was in Hungarian for a EUR account in Austria. No issue.

My swiss banks won't be able to do this in the next 5 years.

I am not affiliated with wise, just a happy user.

that's a very condescending view from you, to be honest.

our paper to a database venue about bringing GPU support to Presto was rejected. one of the reviewers wrote, and I quote verbatim: "the topic of the paper is too practical". I just couldn't help but laughed at it.

it's not stalled, as that would imply that it waits for something, which is not necessarily the case with bubbles. most often it shows lack of proper pipelining or wrong pipeline dependencies (pipeline A waits for pipeline B, pipeline C waits for pipeline B, while pipeline B waits for an event X, now you've just made all three pipelines stalled on event X - not good).

while the title is misreading, when reading GPU profiling data, we do call these bubbles - where the GPU _could_ do something, but it's idle.

any time your GPU is idle = you are losing $$$ = your TCO is going up. you don't want that.

there is a difference but it's overrated. if a theorem is proven, then, as OP said, the theorem is the interface, no matter where the proof is.

just as we don't re-prove Fermat's little theorem every time I use it in a proof, because well, it's a theorem.

I gave them money once on Kickstarter. Never got anything and they held my money hostage for years.

I'm never ever, ever buying anything from Jolla. They can go out of business for all I care.
