Ryan Smith went into this (http://www.anandtech.com/show/7515/nvidia-announces-cuda-6-unified-memory-for-cuda) and points out that the performance overheads are currently undefined. I think the idea is that when Nvidia introduce real unified memory on some product down the line, code written in CUDA 6 won't need any re-write. In the mean time, you're right, it hides the architecture behind an abstraction which has an (as yet) unknown performance cost which is not beneficial for tuned HPC code.
Didn't nVidia have a bit of a problem with through-vias a while ago? Presumably they've got past those issues now. My memories of the bump thing's a bit hazy, anyone else remember details?
I think the cost of the bandwidth needed to punt your 100 GB per day (or whatever) to the cloud isn't insignificant, and when you need to retrieve a couple of terabytes to search for that email your salesdroid sent confirming some contract clause was ok, then the speed could be an issue. Ok so tape's not super fast but read speed isn't subject to external network contention caused by person+dog downloading the latest cute kitten video.
Re: Floppy disk -- I've got one in the car
I use it to scrape ice off the windscreen
Now I've seen it all. An article about a new processor chip and nowhere in it is the clock speed mentioned. So, if the chip speed isn't relevant, just the number of threads you can throw at a job, the new boxes built around this must be aimed at particular workloads. There's a limit to how much parallelisation you can do so it seems to me we're talking about crunching lots of data. In which case, how about the external interfaces? With this amount of CPU, 4 x 8Gb fibre ain't going to cut it. Anyone got any ideas as to just what kind of workload this is aimed at 'cos I'm struggling to imagine it.
Where's the "my mind has just been boggled by these numbers" icon?
I see your reference.
I reckon that the primary functions of a phone are to have good sound (voice, not music) and to keep a good signal. I get infuriated when my phone shows 3 bars of signal until I hit the call button and presto! Suddenly I'm in the middle of a previously-undetected dead spot.
What do I do if I don't have a Win key on my keyboard?
No, seriously, my favourite keyboard is the one that I've used for years (funny that) and it doesn't have a funny key with four-square flag thing on it. Do I fiddle with the keymap or something?
How to judge Win 8 popularity
Take one normal work laptop and replace it with a Win 8 laptop without telling the support techie who uses that laptop. Stand to one side and count the number of times you hear "WTF!?" in response to something the new shiny Win 8 install does or doesn't do. If that number is less than a dozen in the first 20 minutes, be amazed.
Also try Brooklyn lager from the Brooklyn brewery. You can get it in the UK too! I don't normally touch either US beer nor am I a lager drinker by habit but I was pleasantly surprised.
Fiscal third quarter 2013?
Head crunching numbers
So, off the top of my head the sun's power is about 3 x 10^26 W and there are about 10^11 stars in our galaxy...
and to top it all, it's 100 times more power than that which is 3 x 10^39 W, divide by c^2 (lets say 10^17) equals 3 x 10^22 kg of matter converted to energy per second... And as the Earth's mass is approx 6 x 10^24 kg that's 1/200 the mass of the earth converted from matter to energy every second.. ooh my brain hurts
Re: A couple minor bugs to report.
I think you're slightly ahead of me jake, I never had to resort to bathtubs because the 8K in my Acorn Atom was already fitted when I bought it.
What I do remember is taking the case off IBM PCs and pressing the RAM chips back into their sockets (with that slightly distressing crunching sound) to get the machine to boot. Thermal cycling used to make them creep up out of the sockets until one leg would lose contact and then the memory check would fail, so no boot. I think that mem check is still in some BIOSes today. Wonder if it checks beyond 256K these days?

Eddy Ito is right, the belt feeds from the right see http://world.guns.ru/machine/rus/kalashnikov-pk-pkm-e.html
And the guy's left hand does look like the thumb is 'inside' the butt stock, so I'd say it's a PKM with the front bipod folded. Whether he's actually firing at anyone is another question entirely.
And how many journalists sell their photos to Getty without touching them up/adjusting colour balance/applying a filter? Real but shopped if you want my 2p.
Lockheed and defence/defense
I'm just wondering if the increased attention is partly due to the apparent ease with which Gary McKinnon got through the DoD's defences. OK so Lockheed != DoD exactly but some Black Hats reckon it's worth a try.
A bit OT here but just last week I went to see my Mum who had written down a list of jobs for me to do while I was over and she had written it on the back of an 80-column punched card, one of several hundred I gave her when I was doing Fortran.
I still think that if IBM had made their PC/workstation based around the 68000 instead of the 8088/86 then the processing power we'd have had on the desktop in the 90's would have been greater by a factor of 2 or 3. Most 386's were still running 8-bit code when Intel introduced the 486. Intel made the transition from 8-bit to 16-bit to 32-bit take far longer than it would have done if we'd started out with the 32-bit (internal) 68000.
Just my 2p.
Whiteheads on the Greenway is definitely superior to Sullivans. Whenever I visit my Mum she won't have any other.
Not any time soon
I remember working at a car technology demonstration show sometime in the early eighties where Ford showed all the cool stuff they were going to fit to their cars in the future. This included the LED rear lights (took about 20 years) and multiplexed wiring loom (still waiting). I was one of the crew who pushed the demonstator model car onto the stage because the battery was flat and was in the back of the engine compartment and so could not be replaced without dismantling most of the dashboard assembly.
Based on this statistically significant sample of one I'd say "don't hold your breath".
Slider key boards better
The best *keyboard* I ever used (on a phone) was the Sony Experia X1. However it ran Windows mobile which drove me nuts. It used to switch off the phone function just when I answered a call. Currently using a HTC Desire Z which is very good but would be nicer with an upgrade to Android. Other Half loves her Blackberry Torch slider, though.
Space is getting bigger
You have to take into account that space itself has been getting bigger for 13 10^9 years as well. What I want to know is where's the middle? If the universe is expanding and by tracking backwards we come to the idea of the Big Bang, then where (in our current universe) did it happen? And if these galaxies are on the 'other side', then doesn't that mean the universe could be only 6 1/2 10^9 years old?
My head hurts as well (see icon)
AFAIK the problem for Joe Public is the ADSL router. All mainstream OSes have supported IPV6 for years, as have the routers used by businesses. Even Cisco support IPV6 now. However, try finding an ADSL router that supports IPV6 for less than several hundred £ and you're onto a loser. Having said that, devices like the DrayTek Vigor 120 http://www.draytek.com/user/PdInfoDetail.php?Id=71 are getting there.

Title says it all.
Not iphone, not 3G
The antennagate explanation "you're holding it wrong" doesn't apply in this case because the three bars to no signal can happen when the handset is on the desk next to me. I'm in a weak signal area, yeah OK and I only get GPRS coverage. I'm not talking about three bars to zero, it goes from three bars to No Service. That's a BIG difference. Thanks for trying.
Variable signal defeats "real time" display
This kind of thing only applies to the general level of signal. I've lost count of the number of times my phone has rung only for the call to be dropped when I answer. Phone goes "beep beep" so I look at the display which says "no service". So how did it ring?
I've yet to find anyone explain to me how I can be looking at my handset and see it go from 3 bars to no signal in 5 seconds. Any takers?
Does anyone know how much cybernetics Cyber Command will be commanding for the defence of the virtual free world? S'pose that should be defense in this case.
it's DR and Quinch.
Banks sell odd stuff these days
Introductory line is
"Spring IT are currently recruiting for a Software Systems Architect to join a lager retail bank bank based in Edinburgh. "
And I'm not sure whether the Cambridge - Edinburgh daily commute is worth it. Especially if you're paid in lager.
"Your WinAmp receiver is as good in Mozambique as it is in Manhattan"
So why can't I listen to Pandora?
And please explain how I can get internet radio without an ISP-provided (i.e. subscription) connection. And don't say PAYG mobile, there are several dozen places I visit regularly where even the GPRS signal drops below one bar every couple of minutes.
According to Synology's "Compare Products" page it does support Mailstation. And wireless too.
I like the look of the DS210+ spec, includes eSATA and Wake on LAN. Wonder how much more it costs. And for those worried about power it comparison sheet lists Scheduled power on/ogg as a feature too.
Long way round
Last time I looked, the asteroid belt was further out than the orbit of Mars. So going to the asteroids to get a cup of tea on the way is rather like stopping off at Wooley Edge services on the M1 in the middle of your journey from London to Birmingham. And I'm not sure whether the quality of the tea would be any better either.
Wavelength of light
It's because in light wavelengths red has less energy per photon than blue and temperature is a measure of energy density so hot stuff is blue and cooler stuff is red.

Beer for that man!
I think you'll find (according to certain police forces) that
Photographing [anything in the] UK is illegal.
It seems the professor has ignored the Bussard Ramjet/Scoop. If it collects the hydorgen atoms for its fuel using an electromagnetic field (http://www.bbc.co.uk/dna/h2g2/alabaster/A600436) then surely the same field can deflect those atoms if they're not being used for fuel (because we've already got enough dilithium thanks) ?
Remember the gorilla arm!
Don't use PEBKAC, use PICNIC: Problem In Chair, Not In Computer.
Shouldn't that be "from exploding aircraft to exploring security costs" ?
"I use linux, solaris, windows and OSX"
Have you tried Solaris with the trusted extensions? Certain govt. depts. use/mandate it. Not that that's a recommendation, mind you, they can lose data faster than you can say "Don't plug that USB stick in". At least Sun have tried to make a more secure version of their OS.
Fujitsu on strike?
Is this the same Fujitsu whose nice and kind treatment of their staff caused them to go on strike?
Presumably now they've got a new contract they'll be re-hiring all the people they sacked..
Oh wait a minute, did someone mention TUPE?
I'm surprised no-one's made the "if you've got nothing to hide why do you close your curtains?" commentary. Seems like this is a perfect example of why privacy is important.
Not fast enough
I mean, one rocket test every three years!? Not the NASA that put a man on the moon "before the end of the decade". Apollo 8, 9, 10 and 11 all happened in 8 months.
I'm complaining because at this rate I'll be dead before NASA get around to doing anything new and interesting. Come on, there's oceans of methane out there waiting to be the solution to the oil shortage. All we have to do is get up there and collect it! Pedal faster fool!
@AC who likes big guns: I like the Croatian equivalent because it has an over-the-shoulder blast tube which helps with the recoil, apparently.
I reckon railguns are the way forward.
Fusion in orbit

So they're taking a tokamak to the ISS?
600 or 300 ?
"we wonder if the £180 5in, Reader Pocket Edition won't be the better buy"
It's not the touchscreen that's the only differentiator here. The 300 doesn't have Search, SD/MS card slots or annotation. So if you're a student wanting to make notes 600 is the one.
Personally the touchscreen isn't the feature that makes it. The search and being able to use my old MS cards I bought for my P900 (handy way to keep all those white paper & documentation PDFs in one place) are much more important.
Anyone want to hazard a guess when Sony are going to drop MS completely seeing as how their Magic Gate (TM) DRM stuff isn't used and micro SD is more & more common?
Allow the old version
I'd admit I'm not a fan of tab-on-top but there's no progress without a bit of experimentation. This fails when it becomes change for change's sake and fails totally if you don't have a 'look like previous version' option. Some people take time to get used to stuff. What pisses me off is when I get used to some UI/menu layout/whatever, the new version comes along looking different and the only way to keep the older look is to keep the older version!
I'm wondering if Nvidia are trying to get Apple to sign on the dotted line before Intel release the details of their graphics offering and conversely, Apple are stalling for time. Both Nvidia and ATI (AMD) are scared of what Intel can do if they put their resources into graphics as well (hand grenade springs to mind)
I thought the plural of mouse was mouses because MICE stands for Multiple In-Circuit Emulator.
