Sorry, but it has absolutely nothing to do with the real world. They're giving twenty people - ten in experiment group and ten in the control group 30 minutes to do a bit of analysis. And they measure minutes to apply a few changes, without any qualitative measure on how the code is growing. There's very little proof that the refactoring they did made any sense, the sample size is so low you'd never get reliable results and pretty much what you can conclude is that refactoring doesn't make hackjobs easier. Never thought so, that just involves finding the place something's happening and hack it. If it's a good idea, well... it works there and then.

Well somebody has to be the first at discovering something before somebody else can confirm it. And yes, in human years it might take a while to build another billion dollar project to do that. Science works on incomplete information, otherwise there wouldn't be anything to do science on. Has anybody independently verified the Higgs boson yet? All the exoplanets discovered recently? Probably not. That's always how it will be at the leading edge of science.

Once the country tips though, there will be a short and intense period of violence that I hope stays contained within the country, but I fear will spill out to the south. Once that is over, North Korea will be split into two parts, one unified with the south and a portion annexed into China. I have no idea where the split will be.

Somehow I find that implausible, I expect China to take the whole country or not at all. South Korea would be to worried about a conventional or nuclear counter-attack on Seoul to do much of anything while China could probably swoop in and install a new authoritarian regime that by NK standards would seem like heaven, all they need to do is bring them into the 21th century. After that I'll think it'll be a bit like Life of Brian:

Reg: All right, but apart from the sanitation, medicine, education, wine, public order, irrigation, roads, the fresh water system and public health, what have the Romans ever done for us?
Attendee: Brought peace?
Reg: Oh, peace - shut up!
Reg: There is not one of us who would not gladly suffer death to rid this country of the Romans once and for all.
Dissenter: Uh, well, one.
Reg: Oh, yeah, yeah, there's one. But otherwise, we're solid.

So the new spec removes the compiler front end from the graphics driver, greatly improving performance. Only the compiler back end is present in the graphics driver.

Not if you're talking game performance rather than compiler performance I think. From what I understand games generally compile their shaders to native instructions long before they're used, it's not just-in-time compilation like when you download javascript on a page and do it on the fly as you execute, more like delayed traditional compilation until you can optimize for this particular hardware like Gentoo ebuilds.

However, the IR instructions is probably much simpler than the source language, for example Java has tons of classes but only ~200 opcodes. It would make graphics drivers not quite, but a lot more like CPUs running "assembler-ish" code instead of being huge graphics libraries. Basically you're moving most of what's OpenGL/DirectX today over into the application. Stallman might not approve but it might mean more AAA games being able to run on a thin OpenGL Vulkan shim than Mesa.

They've come full circle:
1. AMD announces Mantle, a low level graphics API which may give consoles an edge over the PC.
2. Microsoft panics and announces DirectX 12, aiming for pretty much the same thing.
3. Khronos Group panics and announces OpenGL Vulcan, aiming for pretty much the same thing.
4. AMD announces there'll be no public SDK of Mantle, use OpenGL/DirectX.

So in the end we'll probably have feature parity again. How important it is remains to be seen, outside of drawcall benchmarks it's unclear how much real world difference it makes, what is certain is that it exposes a lot more of the complexity to the developer. That of course gives you more room to optimize, but it remains to be seen how many will be able to take advantage of it.

On the bright side, it might actually mean there's less code that needs to be written and that open source might catch up a bit, it says it'll run on top of all platforms that support OpenGL ES 3.1 which might become a much bigger goal than OpenGL 4.x.

Windows users still need to activate extension visibility manually - even though email-transmitted viruses depend most on less savvy users who will never do this.

...and wouldn't understand even if they did. The only people who enable file extensions are those who understand file extensions, that's a pretty big bias right there. Sure, you can show the rest a file extension but it'll fly right past them just like all the dialogs they don't read but click "OK" on. Like when I accidentally made a rar instead of a zip file and my friend couldn't figure out how to open it. Nice guy, but he doesn't use Google. He wouldn't install 7z or WinRAR unless you pointed him to it and said download this. And I'm pretty sure he'd run absolutely anything I pointed him to.

6. Records and Audits

You agree to keep accurate books and records related to your development, manufacture, Distribution, and sale of Products and related revenue. Epic may conduct reasonable audits of those books and records. Audits will be conducted during business hours on reasonable prior notice to you. Epic will bear the costs of audits unless the results show a shortfall in payments in excess of 5% during the period audited, in which case you will be responsible for the cost of the audit.

Comment: Re:Quite a weak X3 line ... cost determines succes (Score 2) 100

I have no doubt that the Atom X3 is going to make it cheaper to put an x86 into a LTE capable tablet/phone. And Intel gets to get paid for the modem instead of a third party, so it's a big advantage for them.

Not really, the X3s are all made with third party GPU and modem functionality at TSMC. It's a bought design where they add a CPU and a brand to pretend they're competing in a market they're really not. The X5/X7s are Intel's homegrown solution with their own graphics and LTE modem and aimed only at the premium segment. You will not get Intel tech for cheap.

Comment: Re:Deja vu all over again (Score 1) 100

Back on x86 legacy advantages: The other issue I'd raise is that there are quite a few "tablet operating systems" that are languishing in "Not Android" land that might well do well if more hardware comes out supporting x86. The stuff Ubuntu and GNOME are trying to make work might, for example, end up turning into something very, very, powerful if they can get the UIs fixed and if a surfeit of x86 tablets comes out.

Why would that help them? Not being cruel but being open source and ARM a recompile away was supposed to be their big boon and with so much running on Android that's likely the primary source of ports. If they can't make it as a first party OS then they'll never go anywhere in the mobile world that's full of custom, poorly supported, one generation hardware, I don't see any compelling reason why you'd buy a Linux/x86 tablet if Linux/ARM tablets don't sell. And the aftermarket install market is probably just as tiny on the x86 side as on the rootable ARM side.

The degree of technical confidence is inversely proportional to the level of management.
