    TFA author. How does the word "dispatching" hint at the order of magnitude of anything? What orders of magnitude do depend on is your competition. Outdoing a CPU at operation X is …

    A lot of people including "me" (TFA author, of course "me" = larger team) were doing hardware matrix multiplication for many years before 2012 [let's say before deep learning.] I c…

    A group of 100 is 10 groups of 10. Does the autonomy of the group of 10 shrink as predicted by Paul Graham's "virtual person" argument? It might or it might not - and it's certainl…

    If you work on/for a startup and that startup succeeds, it will more often than not have to grow. If you're unlike Paul Graham who sold his startup and then invested in countless o…

    If a collar sits comfortably on a cat's neck, the cat will remove the collar. If a collar sits very tightly on a cat's neck, it's somewhat uncomfortable.

    What if you're not home? It is for such occasions that cat flaps were invented. However, today's cat flaps either open for any cat, or they're RFID-based, and for that to work, you…

    They don't show a comparison to bfloat16 PEs/FMA. IEEE half precision uses a larger mantissa than bfloat16, and the cost of multiplication is proportionate to the square of the man…

    What could he learn from the news that would influence his actions or even opinions? If the answer is "nothing", what's the downside for this guy?

    Wow - an army guy, "the Father of the Nuclear Navy," who gets things about management that half the tech industry doesn't, instead using supposedly army-like command-and-control me…

    It's certainly the case that neural nets work flawlessly because they're like the brain - ask any journalist. Without doubt, an image of the brain enhances NN performance

    (TFA author) If it's a really important patent for an individual inventor as opposed to another one to add to the company's portfolio mainly to grow its size, then of course you wa…

    Not sure why this is being downvoted. I admit that I find it hard to see how to control the exfiltration of data once it's been figured out by a badly sandboxed program. But the id…

    What's the difference between France (lost quickly in WWII), Britain (barely evaded invasion), and the US (not invaded, economy grew during the war)? Is it democracy, free markets,…

    I think grandparent's point was that the first cause you mention - reducing FB's power over users - does nothing for the users if this power instead goes to other 3rd parties, and …

    At my end, I wonder where the author ever saw deterministic computer systems. In my experience, you have to work really, really hard to get even a system computing outputs from inp…

    US laws do not give much protections to citizens of other countries so the American rule of law is irrelevant for them; American and Russian government agencies have equal authorit…

    A company leaving a large market will be outcompeted by a company which doesn't; for companies, ignoring profits kills them. If it's anyone's job to respond to China's government, …

    You mean if everyone teams up and makes their case politically, we'll all make far more, in real terms? So teaming up increases overall productivity? (Not impossible but would need…

    It's hard to know if a patent holder or system architect actually did the work or just took credit for it. It's easy to check if someone can print out a binary tree. Certainly a "s…

    I'd think one is more qualified to address local challenges than global ones. Certainly all those people made their money focusing on the US market, not only because it's big and g…

    Most useful C++ code is either not templates or it's templates which can be instantiated a finite number of times and then used like non-templated code. Most "header-only"/header-h…

    I always thought the opposite - x86 is perhaps more complicated (though ARM is the most complicated architecture calling itself "RISC" by far, especially the 32b ISA), but x86's em…

    rr helps with indeterminism. Memory sanitizers help only a little with that, and, sadly, any thread sanitizer working with POSIX-like threads also helps only a little with that. Re…

    Wow, only learned about rr today - an amazing project! Google for instance reported a sizable number of "flaky tests" which tend to pass but sometimes fail. Always running tests un…
