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 easier than outdoing a GPU at X [assuming the GPU

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 certainly not obvious that the constraints impos

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 others and made lots of money but did not keep work

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 implant a chip into your cat, which I find u

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 mantissa size. I'd expect much lower gains relat

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 methods!

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 want to do prior art search. I wasn't talking

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 idea that systematically addressing side channel attacks

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, or accessibility to German tanks and war planes that i

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 inputs without processing any external events in-between to pro

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, it's other governments', as th

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 more evidence than teaming up increasing bargaining po

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 governed by relatively uniform regulations but beca

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-heavy C++ libraries which present the pro

"I don't believe it's my position to enforce the amount of whitespace another developer has to use in their editor." I suspect this might not be my most popular comment, but I honestly think that this is why tab users mi

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 emphasis on backward compatibility not only for

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. Reproducing the problem (somewhat differently every time) is o

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 under rr would take care of that (since each failure

Couldn't it be both? That is, those are the people who can take risks because they are the only people who can put up with that lifestyle? (Not sure if it's true or more precisely to what extent it's true, in fact I'm pr

Sure, I just think my (not that well thought-out, but still) suggestion mitigates bugs in existing source code with fresh compiler support better than this thing does. A compiler/runtime using new instructions to make instruction addre

Wrt "run with no cache": is a shared DRAM that much better than a shared cache? The DRAM state is affected by what previously accessed it, in fact DRAM effectively has an SRAM on-chip "cache" keeping the current active r

Glad you liked it! It is unfortunately quite out of date as it does not address C++11/14/17; so I put it on github in the hope that people would take over it, as I personally no longer care enough to invest the time it takes (at m

No problem beating most humans already. Beating the best human? How much energy goes into creating a civilization that produces that human? Such humans are rare so you ought to count all the others as part of the cost of making the best hum

Got it, an interesting point and it follows that a use case can be engineered where a GC adds essentially zero overhead over an arena allocator. But in the general case where some objects are short-lived and others aren't, surely manua
