I'm not sure about the CPU numbers either (though my understanding is that modern CPUs are super-quick to power down and back up), but I think 360 CPM is way too high: few people type at 60 WPM, most words aren't 7 letters long, and nearly

Doesn't it already use a preemption timer? If not, how does the kernel regain control once it schedules a piece of non-kernel code aside from that code blocking?

I also wouldn't want to use a cloud storage system that didn't at least have the option to keep a local cache of my data so that I could access it offline and with local speed. But that's how most of the "cloud storage" services I'm familia

Excellent point. Ignoring marketing labels, his statement was as true as can be.

My complaint is spurred by how extremely often it seems that anti-regulation sentiments are expressed in forms like "doing x wouldn't do any good" or "doing x wouldn't solve the entire problem", when in fact doing these things wel

I wouldn't be surprised at all if he'd said that; but you might be thinking of Gates who once said that OS/2 would be the operating system of the '90s. (He was wrong but he… still did all right in the end.)

If 100% of law abiding citizens' guns were to evaporate tomorrow, that doesn't make us any safer, as it still leaves possession of guns in the wrong hands. That seems overly simplistic. How many people that shoot people were — before the

you can change it behind their backs with a single ALTER If you're still there in 2038. And remember to do it.

Hah! Yeah, I could definitely see that being true. It was hasty of me to refer to that as "a mistake": as you say, that was a world in which every byte was several orders of magnitude more expensive. To save a similar amount of money on sto

Same thing whenever those "useless" organizations like the World Health Organization monitor/quarantine people and animals showing new strains of the flu. Afterward, I inevitably hear a "well, that sure was a dud... all that expense and tro

Just like there was never any point in keeping the first two digits of a year? Until Y2K approached and tons of code was still in production that hadn't ever been expected to live that long. It cost companies a lot of money. Why make th

by glhaynes 14y ago
It's not the ALTER that's expensive, it's the people who have to figure out that the ALTER has to be run, set up testing environments, run test cases, verify them, run the actual update in production, etc. (Or: possibly miss it and thus end

Like scissors and pants, which have correctly evolved to "a scissor" and "a pant" where I live. At the risk of your anonymity, anonymous, can you say where this is? I haven't heard that usage before. (Interesting find while googling for t

I can often do that on code I've written or am intimately familiar with, but tons of the code I work on is code that someone else wrote and that I rarely interact with. As a result, I love my debugger.

Just FYI - the little ™ thing doesn't help your arguments be heard. Just the opposite. See also, people who write "Micro$oft".

I'd think the best would be a mix of both.

Not sure this is true. I'm no manufacturing expert, but I've heard a million stories about how intensely involved Apple is in their manufacturers' processes. c.f. how the glass is fitted on iPhone 5s: http://www.idownloadblog.com/2012/09/1

"a laudable bug extremely difficult goal" A rare instance of a typo in a carefully-composed post perfectly illustrating its point.

Why not? I'm pretty ignorant about SVG (and about writing 3D/vector games in general), so I don't immediately see a reason why SVG wouldn't be well-suited to games. Is it just because browsers aren't as performance-optimized for it as they

At this point the onus seems to be on the asm.js-specific-optimizations-aren't-needed crowd to show that they can get performance that's even remotely close to optimized asm.js when using only non-asm.js-specific optimizations. If so, yeah,

Why? If you have reasons to think that the performance tests that he references are invalid or inapplicable, those should be addressed; otherwise, why should he spend his time recreating low-level tests to talk at a higher level about the s

But the JavaScript engine's GC isn't applicable here, is it? Because everything from the asm.js layer up is using a privately-managed heap implemented as a single (?) JavaScript typed array (ArrayBuffer) with no JavaScript-engine-level visi

by glhaynes 14y ago
But at that point the VM-atop-asm.js-atop-the-JavaScript-engine would be the thing doing the GC against its own asm.js-provided heap. (Right?) Perhaps performance would be awful, though I guess I don't immediately see why: if asm.js can get

You couldn't (reasonably) compile the CLR or the JVM to asm.js? I'd assume you could, which would seem to point toward a translation of bytecodes (since that's what the asm.js-hosted CLR/JVM would be doing) being feasible…

That does concern one when it's a video regarding a user interface project, doesn't it? :)

How many well-respected scientists find it persuasive? Not many, to my understanding.

I don't disagree with either of you. :) What I was trying to say was that there are lots of operations that are hardware accelerated in OS X for quite a while.

by glhaynes 14y ago
IIRC, Quartz 2D Extreme (later referred to as QuartzGL) had to do with hardware-assisted rendering/compositing of things like text and certain primitives and, afaik, most of that is still not turned on in shipping OS X and likely never will
