Up to 2 or 3G, but most aircraft should withstand that, even gliders.

There are terms of art, jargon, in many fields that mean something different than the “obvious” reading of the term. I had a discussion with someone on Hacker News recently that just could not understand that “dynamic programming” was a ver

What you describe might be called a loop. In aviation, “roll” describes any rotation (not necessarily full 360) around the longitudinal axis, as “yaw” around the vertical and “pitch” around the lateral axis. ETA: 360 degrees pitch is a loop

Until fairly recently, more people had been on the moon than at the bottom of the Mariana trench.

Sure, just as the bad bad SEC sends men with guns after people trying to do an unregistered IPO. Terrible, the last 90 years of regulated IPOs. The oppression.

By BFT-style I meant employing rounds of voting rather than longest chain, thus being always consistent and eventually available (unlike LCR, which is always available and eventually consistent), but fair enough. Anyways, in the permissione

Happy to clarify. a) Theory: In any engineering or optimisation problem, adding a constraint makes the solution not better , and, if the constraint is binding, worse. So, we would not expect distributed state machine replication (which was

And you think without leetcode questions the despicable biased interviewer from your example would not be able to hire someone from their Alma mater over someone else?

by FabHK 2y ago
So how do you find, in an interview setting, good software engineers? (And better than with LeetCode-style questions?)

by FabHK 2y ago
The latter would be a false-positive, which by assumption is both expensive and rare.

How do you test whether they're problem solvers that also know how to code, without leet-code interviews?

Depends on the jurisdiction, needless to say. I've interviewed in London, say.

Yeah, like Liberty Reserve back in 2006. A centralised stable coin, which was shut down by the US government a few years later for the usual reasons: money laundering, crime, etc. Crypto, being permissionless, is just a bit harder to shut d

Sure. And if you disagree with money laundering choices and tax dodging choices and terrorist financing choices of traditional finance, you can opt for a system that is more in alignment with you. The question is: why should we let you do t

> Asset tokenization LOL. Here's a novel idea: take debt, and chop it into fungible pieces that can be traded (a process we could call "securitisation"). Let's call it a bond. Or: Take equity, and chop it into fungibl

> I still can't send money to an US account without paying absurd fees. You think that is a technological problem? Using crypto appears cheap (despite being inferior technology) because it simply skips 99% of what banks are doing.

Proper OpsSec is a luxury. With crypto: You lose your password, your money is gone. Your password is stolen, your money is gone. A proper solution involves several hardware devices with additional security (iPhone, iPad, Mac, YubiKey with b

I wouldn't call AI a branch of math. It uses fairly basic mathematical building blocks and applies them at huge scale. Not sure there is much cross fertilisation back into pure mathematics. Research in cryptography is much closer to th

Eh, there was also the episode where Tesla introduced a battery swapping scheme only to claim higher green tax credits, without actually rolling it out. It's a deceptive company.

While the industry has changed substantially since the GFC, all foundational derivatives models were basically in place back then.

Not only that, but Dupire’s local vol, stochastic vol (Heston in rates, or on the equity side models that combine local vol with a stoch vol component to calibrate to implied vols perfectly) and jump diffusion were basically in production
