For the same reason that people knock Linux on the desktop -- software, software, and software. The codes that exist for HPC have been developed over years and guess what they target as a platform? UNIX. Do they have a scheduler/queue system? Is it torque/moab? How about a parallel debugger like Totalview? Are the install and cluster control (startup shutdown etc) tools functional and mature? How's hardware fault debugging under windows when headless?
The real question is what % of cycles do they deliver on it, and what's their job payload look like. VT's Big Mac made a huge splash a few years back, but talking to the admin, they broke it up into 64-core chunks and gave each research group a chunk. Most sat idle of course. Also that meant they didn't have to deal with a scheduler/etc.
The HPC machine I run never got that high (mid 60s) on the top500 list -- but we do deliver around 85% of the theoretical possible cycles (penalizing us for maintenance windows, dead/crashed nodes, unscheduled nodes, our 10% of the cluster debug queue) over our four year lifespan.
The color doesn't matter. I could go blind and I could still accurately sort Lego vs Mega/Tyco/Etc blocks. The plastic feels very different to the touch. The clones (even recent models I've gotten in bulk lot buys) just aren't quite as quality as real Lego bricks.
Lego themselves have had some quality issues as they've moved their brick production into other cheaper countries (one in I think what was Chech Republic and one in Mexico? I'd have to go look it up in the book I saw it in...). I suspect it is more of a QA issue; that they have the same problems in Denmark but are much better at catching and removing them before they get to consumers. Or maybe the Danes are just more skilled at machine maintenance.
You're missing my group's most common pasttime: chain-slapping the tar out of the schmuck who ate up all the points and now has the 1st place trophy and a stupid grin on his face at the end of level platform.
Also, you're missing the grab-the-other-dude-and-drag-them-to-their-death. Not that it happened multiple times this weekend. Oh no. Nobody grabbed me while I was trying to make a spinny-to-spinny jump and pulled me down to my doom.
I prefer the following IP-matcher. Shorter, but may not be more efficient for the RE engine to process (I didn't do the analysis). Accepts leading-0s (despite them being uncommon 001.001.001.001 should still read as valid). Doesn't accept 0001, but I'd rather throw that out (something went wrong if you generated a 4-digit ip fragment).
Seriously. I've actually used (and bought!) their products before at work. That was about 6-8 years ago though, so I'll be enjoying a "free trial" as it were. I'm sure if it actually works worth a hoot (and I find it useful) for me I'll probably up for the real version -- I'll want the updates/etc.
Why not one of Turbine's other games, aka Asheron's Call? Monthly content updates since '99/'00. They're just about to pass their 100th (or just did?) monthly update. Plus two expansions. It even lacks the whole dwarves/orcs/elves thing.
Of course, the game does look like it came out back then and a P2 could run it handily, but hey. You claim you wanted content.
... when they had to "test" my clipboard (one of the old-motherboard turned into a clipboard) for bomb chemicals. I'm sitting there going, "what next, you're going to declare it a laptop and tell me to turn it on?"
But then I read the rules and follow them where applicable. "No liquids allowed" -- fine. I take an empty water bottle with me, walk though security with it (they don't even ask), go 10 feet and fill it from a water fountain. All my clothes get packed in 2gal plastic bags -- helps me cram more in the suitcase anyway, so I can go with 2 "carry-ons" and avoid the (new) checked baggage fees.
I hope my next trip isn't trouble though, with a SSD laptop.
Speaking as a regular bus passenger, I'd be quite happy if jackasses with cellphones didn't have conversations at what most children would recognise as an "outdoor voice" on the bus.
Only an idiot is going to try playing a video game that needs windows (read: new enough to not be well supported by wine) on something like an eee pc.
That said, if they'll ever actually release the 1000 in the US, I'm planning on getting one and will probably load WoW on it (cedega/wine) anyway... Just to be able to use the money printing machine^H^H^H^H^H^H^H^H^H^H^H^H^H^Hauction house from hotels/etc.
I think HT means you don't understand the problem: NUMA and HT are irrelevant. Intel is talking 1000s of cores in a single die. That's still a single memory link for the AMD memory-controller-on-chip CPU too. At best you could scale it out to a few dozen links, but at that point the pin requirements for memory get troublesome.
What they're talking about "redefined" is processor-in-memory. Or memory-in-processor. Take it whatever way you want, the result is going to be about the same. Research into that has been going on for quite a while in the academic CS realm.
He makes the claim in the comments about the article that "well who just watches dvds? You have to keep the system busy and test that!" That's about as valid as setting the machine not to sleep and seeing how long it can idle there.
On an ultraportable especially, you aren't going to be churning the CPU with a benchmarking program. You won't be rendering animation frames. Mostly you'll be in a web browser or text processing program, waiting on the user to type something. With occasional spurts of OS and program start/stop. Good gosh it sounds like a MIX of tasks, rather than either extreme.
Not to mention passengers often help avert accidents, so even if they cause some by distracting the driver, there's at least some savings in having them there. I don't know which effect is stronger though. Anecdotal evidence from my life suggests the aversion is stronger.
Think of the site as a resource though. New hire? Search it. Probability of a hit is low, but if you get one, be worried about their responsibility and judgment.
Those same people will sadly discover the consoles aren't much better. The PS3/Rock Band setup downstairs needs far-too-common patching (particularly the PS3) and that patching is usually horribly slow. Not to mention little nuggets like I don't think we can back up our Rock Band "saves", so if the hard drive dies, so does our save file.
That should cover the scaling issues. There is still the need for a good look at security, but that shouldn't be too hard to do -- encrypt/decrypt all data on a password, or maybe even a public/private key pair. You'd have to copy the password or private key to another machine, but you'd only have to do it once.
If you're paying for metered bandwidth, why are you accepting ads in the first place? AdBlock+ solves that problem very quickly.
Past that, maybe we can start seeing more "regular" traffic served over https -- DPI or not, it looks like garbage unless you can break the encryption. If someone comes up with a way to do that, there are a lot more serious problems to worry about than ad injection.
What he said. And I'd add to it, if you do email it to them in any form to make sure that you've covered your own ass. Have your boss email you telling you to do it, and get a hardcopy of that mail signed by your boss.
They'll still fire you anyway, but at least this way you've got a stronger case if they start talking lawyers.

Graduate level economics is almost indistinguishable from graduate level math (or physics), but avoids some of that "hard sciences" feel.

You don't even strictly need a security clearance. Even something as low-end as ITAR (aka: "US Citizens Only"*) can't reliably be shipped off.
*: An oversimplification, but accurate in most cases.

Asheron's Call: Exploit Early, Exploit Often.
Enough said, really.
Speaking as a regular bus passenger, I'd be quite happy if jackasses with cellphones didn't have conversations at what most children would recognise as an "outdoor voice" on the bus.
Why look, a great use for some of the spare cores on multicore chips we have laying around!

Idle cycles while waiting on the physical HD to do something = power savings due to speedstep/descendants of it.
No big mystery, just an author measuring something that's useless and irrelevant to make a splash.

Please before you die, release BeOS as open source. I don't even care if it is GPL or BSD or anything, just toss it out to hobbiests.

An up to date XvT + MMO (think Planetside, but star wars and in space) would rock so hard.
Targeting locks were for pansies. Real men used blind fire torpedoes. (and still hit!)

Ep1-3 and 4-6 are both excellent and are PC-available.
I think guitar hero has a PC port, if you're into rhythm games. (ba-dum-ching!)
