I'd buy that argument if they had actually showed any investment in helping that assumption come to pass. Instead, their ecosystem is a barren wasteland compared to what Nvidia has built.

I think it's the highest compliment I've ever seen Linus express to somebody. And he's not wrong, the hack is adorable. It would never have occurred to me that doing this was even possible in C.

(Theoretical physicist, working in a different area) "Intuitive" means two different things in this context. One is that, over time, theoreticians certainly gain a lot of intuition about how the relevant math works. That's no

Well, the good news is they haven't managed to get through to my (severely eviscerated) Win10 Enterprise system yet - the only Win10 system I run. Still, I guess it's time to finally block the relevant domains in the router to be

I literally hoard good condition X220s, dreading the day when they're no longer fast enough for my needs (hopefully a long way off still). It's the last (going by manufacture date) laptop I enjoy using. The keyboards are superb, t

Did they ever release any substantial information in that regard? The video just shows a few cars slowly driving around empty streets with barely any snow.

Then it should be easy to show a self-driving car working in those conditions. Somehow, despite this argument coming up in virtually every discussion of this kind, nobody's done it yet.

I'm in a similar position, and I've formed the same impression. Furthermore, even though browsers are stuck with JS, given the influx of languages able to compile to JS (or even WebAssembly now) it feels like there should be plent

As a user I love all of those features. Every single one of them makes my adblockers more effective, not to mention they drive more people to use adblockers. :)

Because I don't see any value from using it. It's not easier to read or write, it doesn't force you to keep it sane and simple like a bash/cmd script generally would, and it's just another dependency I don't re

I do exactly the same thing whenever I write C/C++. Genuinely large projects aside, I see no compelling reason to waste your time with build systems. This approach is simple, easy to maintain and lets you get on with writing actual cod

Glad I could help! AdS/CFT is a very elegant idea in modern physics, I hope you enjoy studying it.

by keldaris 9y ago
Since you asked for more depth, I'll focus on the (comparatively easier) task of giving some links to technical literature. First of all, if you already have a traditional QFT background, there's the two extremes of either just ta

Side channel timing attacks have been an active research topic for many years. I'm not a member of that community and I'm sure there are many people on HN who are far better placed to explain the context than I am, but from what I

by keldaris 9y ago
As a physicist, I'm quite used to having to resort to metaphors to convey some ideas to a non-technical audience. If a non-physicist asks me to explain AdS/CFT correspondence, I'm not going to be able to explain precisely why

I agree with the point that it's advisable to start with the Meltdown paper, and have amended my post accordingly. That flaw is much more concise in its essence and much of the context is shared, so it's an easier read.

If I see a programmer saying he/she tried to read the original papers, but couldn't understand this and that, I'll do my best to help them. I don't have a problem with people using metaphors to explain specific points, b

That's not quite right, the NSA is a DoD agency and the highest ranking civilian in it is the Deputy Director. The Director of the NSA is a military officer also in charge of USCYBERCOM. The FBI and the CIA are indeed civilian agencies

As far as I know, they're a combination of it being hard work and there just not being enough of a qualified developer community around Pidgin etc. to put in the effort required. I think people generally underestimate the sheer amount

Because reverse engineering some IM protocols is far from trivial. Skype, in particular, is a nightmare of obfuscation, as I understand (second hand knowledge from having wanted to replace it with Pidgin in the past, I haven't tried re

My comment was prompted by the fact that the majority of comments in this thread relate to HEVC vs. VP9. It was my mistake to post it as a top level comment rather than a reply to one of the pertinent comments in the thread. You're rig

People can congratulate themselves as much as they want, but the fight won't be won until VP9 is actually (technically, not legally) superior to HEVC in terms of the available implementations. Right now, VP9 encoding speeds are ludicro

I don't have any facts that aren't already public - the official as well as the leaked roadmaps of the CPU manufacturers and general knowledge of how the industry works. What I'm wondering is - what, specifically, do you thin

There's no point in waiting. Neither Intel nor AMD will significantly adjust their roadmaps due to these issues simply because they don't realistically have the flexibility to do so. Evaluate your threat model in the context of Me

Performance at the expense of security is a compromise made daily in every aspect of IT. The only way to make systems perfectly secure is to make them unusable. Now, you can certainly argue that this particular tradeoff wasn't worth it

I'd never heard of this graphics engine before (not my area), but the web design is wonderful. No extraneous JS crap, loads almost instantly, looks great. I wish more of the web was like this.

I'm frankly shocked Linus was anywhere near as restrained as he was upon seeing this monstrosity. Nothing of this sort should ever make it into the kernel without explicit and loudly announced opt-out switches. If anything close to thi
