> Brazil One of the most violently unequal countries on the planet. Very proficient however in virtue signalling.

Not true.

There has to be some change in the code, and they will not share the same semantics (and perhaps won't work when retractions/deletions also appear whilst streaming). And let's not even get to the leaky abstractions for good performance (watermarks et al).

They did, and their product is great.

It is the only database/query engine that allows you to use the same SQL for both batch and streaming (with UDFs).

I have made an accessible version of a subset of Differential Dataflow (DBSP) in Python right here: https://github.com/brurucy/pydbsp

DBSP is so expressive that I have implemented a fully incremental dynamic datalog engine as a DBSP program.

Think of SQL/Datalog where the query can change in runtime, and the changes themselves (program diffs) are incrementally computed: https://github.com/brurucy/pydbsp/blob/master/notebooks/data...

That's Feldera for you. It has a full blown SQL Api.

Materialize is cool as well, but is sorta hostile to self-hosting.

What does Arroyo have that Materialize or Feldera do not?

It seems that Arroyo is a strict subset of those.

There is no independent component of a country. It is very naive to claim so.

What kind of non-authoritarian country arrests people for merely cursing at politicians on twitter?

Moreover, what kind of non-authoritarian country issues hundreds of thousands of rulings by its Supreme Court?

The Brazilian Supreme Court is an unelected entity that has complete control over the country, and firmly issues unappealable censorship arrests.

There is absolutely nothing this tyrannical in almost any western democracy, sans the UK.

It's cool that "we" have a payment system, however, I would never be comfortable using something whose people in charge are those that keep us (not me particularly because I've gladly left the country almost a decade ago) in this misery.

I use Crypto for everything you've mentioned. It's instant, almost free, and alexandre(he deserves a lowercased a) can't take my money if he feels that writing his name in lowercase makes me unworthy of my civil rights.

The Brazilian government is a *very* corrupt authoritarian oligarchy. I would take any US company over that any day.

It's naive to believe that the Brazilian government has the population's best interest at heart.

It is a Russian-style aristocracy with zero freedom of speech. I genuinely believe that Lula as a "people's person" cared for the "people" at some point, but that's long gone.

Brazil is a failed state with 52(!) GNI. That level of inequality signals a gargantuan failure of the state.

My hope for the country is that is gets split at some point, since as it is, it only "works" for a very small minority.

What?

As somebody who is Brazilian, I gotta tell you.

Comparing the US with Brazil, especially with respect to some violence-adjacent statistic, is absurd in a way I don't think anybody from anywhere aside from perhaps South Africa could grasp big is your privilege.

This is 100% it.

D-Wave is great at solving issues that directly map to what it is physically solving i.e approximating the state of lowest energy of some entangled (sparse) lattice with fixed topology.

The point is, what if certain problems can be mapped to it such that business value could come out of it?

So far this hasn't been a thing, but at least it can do something non-trivial. There's no other quantum computing device that is as close to attaining real-world usefulness than D-Wave.

They did refuse to take it down.

You have no idea how many emails were exchanged, attempts at explaining them what a commit log is, what verified commits are...to just refuse to do anything until Stanford weighed in.

It is incredibly condescending to say "arXiv is not a place for a copyright strike". as if I decided to start one.

If somebody gets robbed in front of a place of worship/whatever, would you scold the victim by saying that's not the place to get robbed?

Incredible.

I have zero compassion for ArXiv.

Allow me to share a horror story:

I was the victim of a pretty bizarre super in-your-face academic theft. Someone snooped a half-finished paper draft of mine off GitHub and...actually got it published in ArXiv and a "real" journal: https://forbetterscience.com/2023/10/30/stephensons-alternat...

In spite of having a full commit log (with GitHub verified commits!!!) of both the code AND the paper, both ArXiv and the journal didn't seem to care or bother at all.

I went all the way to contacting Stanford, the institution that the thief falsely pretended to be affiliated with, to get them to help me with this.

Stanford contacted ArXiv, and ArXiv then: 1. Removed the thief's upload: https://arxiv.org/abs/2307.14810 2. Allowed the thief to copyright strike MY (!!!!) own research: https://arxiv.org/abs/2308.04214

How does this make any sense? You remove somebody's stolen content, and then allow the thief to copyright strike it? what the fuck...
