The half billion monthly active users and $5B annual revenue beg to differ. And it trickles down in the form of paychecks — does that matter?

Is it mostly engineering or other roles being laid off?

I want that. I think that refusing to fix a life-or-death bug for 8 months is criminally negligent. Especially when millions of Pixel 6s are out in the wild, as an essential utility for millions of people.

Tbh I always direct people who want to read old important papers to lecture notes or textbooks, at least in distributed algorithms or CS theory. I've found that the original papers are always super dense and the material has usually ev

yeah if someone proved P != NP --> OWFs, that would be the seminal result of a generation of work in computer science theory.

Just wanted to emphasize your point about "worst case hardness" -- even if 3SAT turns out to be hard (due to P != NP), it is only hard in the worst case (for a very small subset of all possible 3SAT problems). Most 3sat problem in

How is this different from saying 80% of engineers went to engineering school? "The observed placement rates would imply that faculty with doctorates from the top 10 units are inherently 2 to 6 times more productive than faculty with d

The main question that requires answering, I think, is why we let Tether and Bitfinex print a bunch of Tether and buy a bunch of Bitcoin during low volume periods. The Bloomberg report et al and the SEC both suggest that this is happening,

Note, "The majority of Bitcoin trades are now conducted in Tether, 70 percent by volume. By comparison, only 8 percent of trade volume is conducted in real dollars, with the remainder being other crypto-to-crypto pairs."

Why is this flagged? The argument presented is very reasonable and requires a rebuttal. It is also an uncommon argument I haven't seen previously on the front page. The main argument is that Tether is acting like an unregulated central

It seems to depend on how specialized you are. I bet it would be very difficult for any automated tool to understand how good a paper is. Until then, you have to rely on other people who understand the paper, to get good paper recommendatio

To be fair, it is quite murky to what extent groups like Al-Haq are associated with the PFLP (which, with its history of aircraft hijackings and suicide bombings, is undoubtedly a terrorist group). There is plenty of purported evidence of f

A correct Multi-party computation protocol (MPC) by definition is private. MPC from its inception has used zero-knowledge proofs as a building block (i.e. see the GMW compiler from the 1980s) (though other approaches exist).

Pretty sure Paxos is easily extended to the byzantine setting with digital signatures (i.e. Byzantine Paxos has also been around forever). Also PBFT has been around since the 1980s. Only distinction is classical consensus is permissioned wh

Honestly I think your comment is so broad that it's vacuous. In this specific case, mitigating the spread of zebra mussels through prevention has a clear and explicit benefit, in preserving natural north american ecosystems. The collap

I recall paper trail had some errors in their post on paxos (iirc), which made me more skeptical of the publication in general. But these are good links!!

no CRYPTO or PODC?

Maybe historically, before the public even had computers, but do you have anything to support your claim for cryptography in the modern era?

there are also a variety of problems that are hard to approximate.

(In the context of embedding paxos in some sort of proof-of-concept replication system. Something like Multi-paxos.) You're right, I guess we generally talk about state machine replication instead of one-shot systems.

Right, when run in a fully asynchronous setting, where the network adversary can always deliver messages in the order of their choice, the FLP impossibility result says that Paxos cannot terminate. Thus, for Paxos to make progress, the netw

No complexity is hidden here. Streamlet is (essentially) in the same setting as paxos. Just like in paxos, messages can take arbitrarily long to deliver. The only assumption is that clocks are synchronized, which is much, much weaker. (We
