Anyway, care to provide a citation about the "terrible floating point performance"? As far as I know AMD Opterons has much better multicore floating point performance / dollar than Intels.
He's probably referring to the Buldozers which do have terrible FP performance, primarily because two "cores" share a single FPU.
For example, while the FX-8120 gets about 77% of the score the i7 2600k gets in PassMark, in a very floating-point heavy, multi-threaded rendering application the 8120 gets about 51% of the 2600k.
You always bought Intel processors* even when they were far inferior compared to AMD. Now stop that, and just buy AMD processors even if they may perform a bit lower in some measurements in benchmarks (and better in a few others).
While I'd love to buy more AMD, I've had quite a few bad experiences with the motherboards for AMD, while I haven't had any issues with the Intel based motherboards I've bought over the last 5 years or so. As such I'm keeping to Intel for now.
Generally kept to Asus, and not the cheapest models. Is this just my bad luck or?
The deeper idle states (C-states) are so power efficient that the best power savings comes from doing everything as fast as possible and then returning to the deepest idle state
I've seen this stated many times, however I find that on both my old and new laptop the CPU fan consistently runs at a higher RPM compared to when if I force the scheduler to be conservative. I guess I should measure battery time some day to see if it's just an illusion or not.
As a physicist, I would like to read a book on why people outside the field consistently refer to large things as quantum. It means 'the smallest discrete amount possible,' not large, composite chunks.
It's not about size. It's used to denote a large discontinuous transition as opposed to a continuous transition. Like the transition, "jump", of an electron from one energy level to the next.
FWIW I was thinking the same as you until I was explained this, and as with all sayings it's not always used appropriately.
I'm not all that familiar with Apple, but KDE is head and shoulders above Windows 7 (I use them both). How are they "losing competetiveness" to MS?
While I agree that there are a lot of very nice concepts in KDE, the "build quality" is miles below Windows 7, at least since the switch to KDE 4.x. For example, I really like the concept of activities, but I've yet to have it work reliably for more than 30 minutes. Speedy desktop searching is nowhere to be found, even with a SSD (strigi just doesn't work). Essential programs crash far more on Linux for me than in Windows.
The Linux fragmentation doesn't help either. Want to open a PDF you downloaded in Firefox? Then you have to fiddle a bit. In Windows it automatically finds the default PDF handler.
So while I try to enjoy KDE on my laptop, I quickly find myself longing back to my Windows 7 desktop.
Obviously Skydrive is of no use but there are several other alternatives that would be better suited to this purpose although if, as he says, it is for use while travelling an internet based system is useless.
That's why I liked Crashplan when i first saw it. This may sound like a sales pitch but I'm just a happy customer.
With Crashplan you can have multiple destinations for your backup set. I usually have three: - same HD in case I accidentally deleted some files. - USB HD for faster recovery in case my primary HD breaks. - Online "in the cloud", in case my house burns down etc.
Crashplan detects when I plug in the USB HD and automatically starts running updating the backup on it. If there's no internet the first two destinations will still keep me pretty safe. Once the internet is back it catches up on the cloud destination.
It works just fine on my Linux Mint laptop as well as my Windows desktop pc.
The same thing was mentioned above, but all a hacker needs is the contact list. They can spoof your email address and bypass Microsoft entirely afterwards.
They can. However the recent Hotmail spam I've gotten actually seem to originate from Hotmail servers. In addition the spamming stops once the user changes the account password, which wouldn't happen if they spoofed the sender address.
Group email. You know, take the time you did with FB and include those you want in the group. No difference.
Big difference: you don't have to know the details for everyone in the group. It's enough that at least one member of the group knows the details, but it doesn't have to be you. And different people can know the names of different people, and invite them to the group.
Due to this I'm now effortlessly chatting with my gaming clan from 2004, which split up many years ago, and I only recalled the name of one of them.
Can it be done via email and such? Yes. But I must say Facebook makes it a lot easier and more convenient in this case.
reCAPTCHA is the worst of them all (owned by the arrogant Google assholes). Is almost impossible to read what's there[...]
I find reCAPTCHA to be one of the easiest captchas to get correct. Sometimes you get an oddball one, but I've never gotten two such in a row. Why all the hate?
And no funky UI changes that keep tweaking the way stuff acts.
Funny, because that's exactly why I ditched Chrome and went back to FF. They changed and removed functionality several times in the year I used it exclusively. And extensions couldn't access the relevant data to replace the lost functionality. Finally grew tired of this and the lack of cache settings, and I've been using FF again since.
For example most, if not all, games from Codemaster uses a reasonable conversion. F1 2011 costs $37.50 or 29.90 euro, depending on if you're in the US or EU. Ok so it's not perfect but it's at least reasonably close.
I saw the episode when it first aired. He said "[we wanted to do some more shots] but look what happened" in the VO that showed the car being pushed into the garage by hand
I saw the episode when it originally aired as well, and I quite distinctly recall mentioning to my buddy that it was silly to estimate the range by the usage on a race track, since nobody would, or should, drive like that on public roads.
I think you're mixing it up with the part that comes a bit later, where he says
And it appears you don't get much in the way of reliability either. [Shot of Tesla driving slowly along track] Oh I don't believe this, the motor's overheating and I got reduced power. [Exterior shot] While it cooled down we went to get the silver car out again. [Shot of silver Tesla in garage with doors open] Only to find that while it was being charged it's breaks had broken. So then, with the lights fading, we had no cars at all.
I haven't followed the case closely, I have no idea how this specific segment holds up.
He also said some downright false things, for example that it had run totally flat and had to be pushed back into the garage by the crew to be recharged [...]
He said no such thing, at least in the episode I watched. What he did say was
This car then really was shaping up to be something wonderful. But then... [cuts to shot of the Tesla losing power followed by the car being pushed into the garage] Although Tesla says it does 200 miles, we worked out that it would run out after just 55 miles.
Emphasis and errors are mine.
So yeah, the images were overly dramatic which makes the whole thing seem bigger than it is, but that's not really that uncommon in the news world now is it.
However, there is one thing I am confused about with the muon: it can decay?? I thought fundamental particles are the smallest that small can get, as in, you can't get anything from "splitting" it, there is no substructure within?
Yes, the muon decays. Just because it's a "fundamental" particle doesn't protect it from E = mc^2, so to speak. Since the muon is a heavier version of the electron, it is also more energetic, and thus the tendency is for it to decay to the less massive/energetic electron.
I can't imagine that you're going to be making the most of the hardware somehow.
Depends on what you do with it. Consider this article about PCI-Express scaling on a 5780... A lot of games get 75% FPS or above using only a 1x PCIe port compared to a 16x. Keep in mind that the 5870 is a high-end card, and the 520 is a low end, so I don't think the performance hit will be that bad.

Is anything major using Python 3 already?
Guess it depends on your measurement. Blender uses (hosts) Python 3 for scripting.

Reading comprehension fail. I read "Doom 3", missing the little "on" there. Doom didn't exactly fly on a 386, but yeah ;)
Also multi-player, always waiting for the 386 to finish loading the level.
Which is understandable, given than the min specs is a 1.5GHz CPU :)

They already said it will be exposed as an option, so that's already covered.

I for one usually have to re-load four times to get one that I think I can read, fail it after all, and have to try again.
You do know that you only need to get one of them right, right? And that one is usually pretty easy.

And what would you do, then? It's not like it can magically decide which of the two companies you want to see when you input the URL.
I'd do what Wikipedia does, turn it into a disambiguation page, listing all relevant pages.
And yet Steam has that USD=Euro conversion
This is entirely up to the publisher.
For example most, if not all, games from Codemaster uses a reasonable conversion. F1 2011 costs $37.50 or 29.90 euro, depending on if you're in the US or EU. Ok so it's not perfect but it's at least reasonably close.

Sure it could keep us from making stupid mistakes, but it could also lead to abuse of the system.
