    The difficulty of engineering good metrics & keeping them honest is generally underappreciated. Perhaps the people that appreciate it most are those that were in the trenches when VaR was conceived.

    Men. If you know a female colleague is getting paid a *lot* less than everyone on the team? Offer to give up your year-end bonus to her. In my experience, HR will core dump, unable to handle that request. When they say "we can't"? Yeah, you found another problem.

    Yes, please do this. I was so thankful when a colleague shared his so I was able to negotiate better knowing that HR was totally low balling their first offer.

    Hey - you keep on inferring that we are being paid by a competitor. Can you explain how this would make an unhackable wallet hacked?

    "how did we know that all these people weren’t paid by a competitor to do this?" Even if we were paid by a competitor, it wouldn't matter, would it? The vulnerabilities are still there!

    Thanks to for speaking to us. I doubt will be spreading this one.

    I got the chance to speak with to get the researchers' side of the story in the Bitfi saga and am glad to announce that something is now published to that respect.

    The stupid ad-hominem needs to stop The vulnerabilities have been found. It doesn't matter WHO found them or WHAT their motivations were. Trying to do this again and again only makes one of us look bad.

    "how did we know that all these people weren’t paid by a competitor to do this?" Even if we were paid by a competitor, it wouldn't matter, would it? The vulnerabilities are still there!

    This is a reference to the movie "Sneakers" - Janek was a character who made a device that was implied to be able to factor RSA modulus numbers in trivial time. Several characters were killed over said device. Anyone got a better answer than "anonymous proof + destroy it"?

    Thought exercise: suppose Janek's box is real, and you just invented it. What would you do?
