It's a sure fire way for Nokia to claim financial damages from MS due to one of their employees breaching a confidentiality agreement. There are likely to be some very nasty (for MS) clauses within the contract with Nokia, and I imagine that figured pretty heavily in the decision to fire the guy (that and attempting to demonstrate to Nokia that they are serious about not allowing a breach to happen in future)
So. I go into best buy. I buy a PC with windows 8 installed, and some of that money goes to MS for the license. Now, you are seriously trying to suggest that MS will have forced best buy into locking the PC to windows 8, thus making it *impossible* for me to use windows9 when it's released, thus losing MS future sales?
Whether or not you keep windows8 on their is irrelevant to MS. Even if you install linux on the box, they've still made a sale (in the all-too-common hypothetical situation above).
The only people who will actually benefit from this are best buy, PC world, et al.....
"Oh, you want to install a different OS? Sure, that'll be 30 pounds please..."
"Oh, you have a virus and want to re-install the OS? Sure, that'll be 30 pounds + a virus removal fee please..."
We need to get creative! Just pretend that I've just insulted your operating system of choice. Go on a rant. I'll respond with something about linux running on a beowulf cluster of laser headed sharks, and with any luck we'll be able to get this one back on track.
Now all we need is a link to a web site. I, like many others, can only enjoy reading slashdot when I know that there is a small web server somewhere in the world, all alone, sitting in the dark, crying at the load that's been placed on it.....:*(
I've seen nonsense idea's like this rolled out before. Looks great on paper, until an inevitable stream of people start chanting "I've lost my iPad again!". For some reason, it seems to be much harder to lose the office printer. Can't think why?
I like the way they decided to spread the article across 38 pages that each take a minute to load. Oh. Spoke too soon. Now it seems to be slashdotted. I'm guessing this means no one will be reading that article. It's phoronix though, so I'm guessing the rest of article will be something along the lines of:
* Here's a test of lots of 3D graphics cards from AMD.
* Now let's conduct a large series of 2D tests, all of which are entirely irrelevant for users of 3D graphics cards....
* Conclusion: Could this be the year of linux on the desktop?
"What's that? You want to look up something on Wikipedia in Internet Explorer, then go back to Word? No less than 4 mouse clicks and three full screen changes to get back there from here". - Metro UI
I'm imagining someone owns a patent for doing it in less clicks.
at £6 a gallon for fuel (in UK), over the course of 100,000 miles (a conservative guess at the life of an engine) you'd be looking at fuel costs of £30,000 for averaging 20mpg, and £27,272 if you averaged 22mpg (assuming that this stop-and-go causes only a very minimal mpg saving - although that very much depends on your daily commute. i.e. someone living in london is likely to see a larger saving than someone living in the country). So over the lifespan of that engine you'd get a £2727 saving - assuming that the cost of petrol stays the same for the next decade or so. Given the somewhat crazy increases in the price of petrol in the last year or two, we can assume the savings will be much greater than that!
Last time I replaced an engine in my car (which was about 10 years old) the cost of a used engine (with 40k on the clock) was £800 from a breakers yard, and the cost of fitting was about £350 IIRC. Yes you could buy a brand new engine (which would cost mega bucks), but why would you buy an engine that's going to cost 3 times the value of the car at that point?
... Although I'm sure it's no easy feat, I'd be kinda more interested if they couldn't break the record (thereby implying we may be at the end of moores law)
I had a similar - if completely different problem. I got fed up trying to work with the constant whirr of my GPU/CPU fans coming from my desktop PC. After a bit of experimentation (replacing fans with quieter ones), I finally plumped for some of this stuff, and the results are pretty impressive. If you're an extreme overclocker it's probably not for you, but for everyone else it's a godsend!
User convienince mainly. Currently if you are an IE user, to get an improved search engine convieniently at your finger tips, you need to install some software from real networks. If MS were to buy yahoo, they'd be eschew the current malware distribution model, in favour of including the Yahoo toolbar with the IE installer. I think you'll agree, this is a compelling reason for MS to buy Yahoo, and a situation where the real winners would be us, the consumers.....
It's a rare program that can keep putting data in on every cycle so it makes sense to have one FPU per two cores.
No, it's actually very easy. Avoid dependency chains.
If your compiler's any good the second loop will run about twice as fast as the first because it keeps the FPU busier
Uhm. Wut? It may run faster, but not for the reasons you state.....
1. If your compiler is any good, they will run at the same speed. Compilers aren't stupid - a good one would move the computation on the SSE/AVX regs. A semi-good compiler would find the second version harder to optimise. KIS-KIS!
2. Continually assigning a value to the same variable is a big performance no no!! (which you are doing for both i and the total).
3. The second version is a classic case of a naive optimisation that causes a buffer overrun. eg, #define arraySize 1
4. Neither version makes efficient usage of the FPU. "Load -> Add -> Store" is bad. "Load -> Do Tonnes of Stuff -> Store" is always better. The time spent reading/writing that float (from the array) eclipses the time spent adding
5. If arraySize is sufficiently large, the only thing that would improve performance would be pre-fetching/streaming (or striping if you are really desperate).
6. By unrolling the loop you have halved the number of integer comparisons. This has *nothing* to do with the FPU at all.
The effect is much more noticeable when the code has lots of divisions and square roots.
7. Incorrect. If you are doing lots to that single float within a tight loop, the saving of the integer comparisons becomes less and less noticeable.
8. As the number of instructions increases (in each iteration), so too does the size requirements for the instruction cache. If by unrolling the loop the instruction cache is exceeded, your performance will drop like a stone....
The basic premise for all Zynga games is something like this:
* Game is free to play
* Game lets you click on something (to buy, attack, build, whatever) once every N minutes of hours.
* After a number of days of clicking, you win some new item
* You can bypass the whole thing by simply coffing up some cash in the ingame shop.

That's not true. There's always the AOL browser! *ducks*

but the govt. would need to select one and oversee it.
But that's the entire problem though isn't it?

What? Your ATI does raytracing in realtime at 1080p?
You want to wait 15 years for a frame?

but to my mind and to most security professionals, the cloud doesn't exactly give me a warm fuzzy
Which is why everyone needs to start referring to it as the fog :p

So yes. I'd go for fuel savings over the engine.

What would MS gain by buying Yahoo?

Most programs can't saturate the FPU anyway.
Well yes. No one uses the FPU anymore.
It's a rare program that can keep putting data in on every cycle so it makes sense to have one FPU per two cores.
No, it's actually very easy. Avoid dependency chains.
