You're correctly stating the conventional wisdom for properly managing air in a datacenter. However, the whole point was that Intel was doing their cooling with outside air, minimally filtered to see what the effects of disregarding the conventional wisdom might be. So, one way to improve the energy efficiency might be to use a chimney to avoid having to use fans.
Have you ever ridden on a trolley bus? MUNI in SF has had them for ages. I think the newer ones are better but the old ones had the worst motor control system. Just one long shudder as you rode them.
No, the reason they won't replace Javascript in the browser is that they are not *in* the browser. Writing an alert() function is trivial once you're integrated into the browser.
His point was that using more memory will not necessarily make something faster. There are algorithms that benefit from more RAM and algorithms that do not.
The inverse, that using more memory will necessarily make things slower is not true either. The question is how is the memory being used. If you are accessing more memory than you need to, yes, things will be slower. However, one of the reasons to use more memory is to pre-compute difficult things so that you can look them up rather than performing the calculation again. That, essentially, is what JIT is.
Well, there's no such thing as a "JIT based language." There are JIT based implementations of language runtimes. You can compile Java or Javascript or Ruby to machine code if you like. There will be some level of runtime support needed, just like C++. There will be some amount of runtime overhead that is incurred by the features of the language. As the GP stated, the dynamic type resolution means that you take a hit at runtime, not compile time.
Hmmm...if you're on a highway (not freeway) in the US, usually the stop signs are only for crossing/entering traffic, not on the highway itself. I drove across a big chunk of England once on their equivalent of a highway and every kilometer or so there was a traffic circle which meant you had to slow down, even when there was no traffic in the circle. It wasn't very pleasant.
I went to go see the new Indiana Jones movie here in Tokyo at Roppongi Hills. Stadium seating, clean theater, and beer! All outrageously expensive of course, that's the main drawback. That, and no pause button, as the beer rental forced me to miss a bit of the movie.
Even worse really. It wasn't saving "Mickey" from the public domain. It was saving some really old Mickey Mouse cartoons from the public domain. More recent works would have remained under copyright as would Disney's trademarks. So Disney got very little and screwed everyone else over very big.
How am I supposed to take responsibility for this?
Two ways.
1) Keep passing it up the line 2) When someone brings it up, don't blame the person asking. Accept that your company refuses to make the data available and let them know - but it's not the fault of the person asking and it's not because the calculation is too difficult to perform. Asking that customers STFU and GTFO when posing a perfectly reasonable question is not the right attitude.
Dead on. I think the whole thing is nonsense created by people who want to appear insightful. "Think about the people 10,000 years from now" - wow, what a deep thinker!
If you follow this logic, then anything that could potentially exist for 10,000 years and might be fatal to someone needs to be properly labeled. You'll know who to blame when your Twinkie wrappers start getting weird hieroglyphics on them.
Cruise missiles aren't the same as UAV's. They fly to a preprogrammed target, don't take evasive action, don't drop bombs and then come around for another pass, don't have surveillance cameras, etc. They are certainly not air-to-air fighters and they're not even as capable as currently remote-controlled UAV's.
UAV's are great for fighting an unsophisticated enemy. However, the current crop is remotely piloted and not suitable for air-to-air. I think a sky filled with UAV's over the Taiwan Strait would rapidly become the Taiwan Strait filled with with crashed UAV's once some broad spectrum jammers were turned on.
Ummm, no. Text in Japanese is usually done as either Shift-JIS or EUC and occasionally as Unicode. 2-3 bytes per character. Graphics are used about as much as on English web pages.
As for using cardboard boxes for weights on the ends of the wings - not exactly scientific is it?
Not "scientific"? Why not? A cardboard box with a properly measured amount of sand or iron shot in it is a very easy way to get a properly calibrated weight. What would you suggest they use? Carbon-fiber tubes filled with depleted uranium? Would that be "scientific" enough?
Science isn't about the tools - it's about the methods. Spending money where you don't need to doesn't increase the quality of the final product. These guys have built amazing aircraft. It's one thing to be critical of people who haven't delivered but these guys have.
As far as things blowing up, that's happened in just about every rocket manufacturer. You might recall that Morton Thiokol (makers of the SRBs for the Shuttle) had a big explosion back in the 80's. An X-15 blew up in a test stand. It's part of the risks of the business.
Well, given that Scaled Composites is one of the most experience builders of aircraft with composite materials I would expect that they know what they're doing.
It is kind of fun that it looks like they're building a spaceship in a big garage. Factories are not always what you think they will be. I used to work for a company that built mini-supercomputers. Our factory was surprisingly modest. I used to love that we would make the official stickers (you know, don't stick your fingers in here or you'll get electrocuted) with the laser printer and cut them out with scissors.
MS Project is designed for planning projects like building a house or installing equipment in a data center. Look at the examples in the manual. Those kind of projects work really well in a waterfall model since most of the tasks are predictable. I don't think they're really selling it to manage software projects - the market for project planning for building houses and such is much larger.

The renters and used game buyers *are* their customers.
The price that you can sell the game for is factored into people's buying decisions.
For example, say that there was no used car market. Would that affect what people are willing to pay for a new car? Of course.
Destroying the used market will simply mean that the retail price will go down.

It's easy - if you've never heard of it, it's a third tier college.
Australia is pants :-)
I just hash my pants. That's the best.
Apparently thinking about Javascript is detrimental to my sense of humor.
No, the reason they won't replace Javascript in the browser is that they are not *in* the browser. Writing an alert() function is trivial once you're integrated into the browser.

That explains some of the weird postings. The COBOL must be filtering across.

Yah, no kidding.

That was in the movie. Read the book, it's much better.
The technology will get there, but it's not there yet. There are a couple of steps between "it's not hard to believe..." and "here it is".
