A "true" quad-core means that all of them share the same L2 cache, AFAIK. Basically, performance benefits as they can all use the same high-speed memory cache for L1 misses. This is also extremely useful in the case of multiple processes which aren't bound to a CPU. If process A is scheduled on processor 1, then 2, then 3, then 4, there are going to be a lot of cache misses (since it's in no CPU's L1 cache). With two dual-cores bolted on to each other, processes switching from processors 1-2 to 3-4 are going to incur severe performance penalties as any relevent memory is fetched over the memory bus from RAM.

This new memory might help also with quad cores and beyond.
Not really. The huge factor involving multi-core processors is sharing caches. While I'm sure it'll have some benefit, it's not something holding back further improvements.
We can have nukes, but North Korea and Iran can't.
Precisely. If you would please go read the NPT, of which Iran, North Korea, and the United States are all signees of, I'm sure you would see why this is the case. Or you could continue to join the discussion without any knowledge on the subject whatsoever. That'd be cool, too.
I disagree. The reason they have this momentum and are in such a powerful position today is probably precisely because of the way they manage these projects. What do you think they did when they didn't have the market share they have today?
One is just a weekly status update with your team lead, which seems fine.
The other two, I'd wager, are probably pretty short, unstructured coordination sessions. Making sure everyone's on the right page, person to person. Also, perfectly fine.
Meetings aren't necessarily a bad thing; it's the completely worthless, unproductive types that you need to watch out for.
I'm not sure why some variant of this argument wouldn't hold true for GPUs, but there is a practical limit to how many cores a CPU can have on-die.
With the first set of dual-core CPUs, each CPU has its own L1 and L2 cache. However, this isn't optimal -- basically, this heavily favors scheduling processes on the last CPU which they used, to increase the likelihood that needed memory is already in the L1/L2 cache. So, most current dual-core architectures use individual L1 caches per CPU, but a shared L2 cache. This seems to work well for 4 cores on die, and possibly 8.
Unfortunately, the logic to sort out all the caching interdependencies of any more CPUs than that is prohibitively difficult and time-consuming, having (I believe) an exponential increase in complexity. Thus, it's unlikely we'll see 100 cores on one die any time soon. Who knows, though? Maybe we'll have multiple L2 caches, with each one being shared by 4 cores, then move the L3 on die and have it shared by 4 groups of 4 CPUs. Cache affinity issues then become more of a pain in the ass for the scheduler, but I don't know enough to say.
Everyone cares what there friends think, it's just that there is a recent trend to cultivate the image that you don't care what people think - but it is still an image, and you are still trying.
Not really. There are people who go to great lengths to present the image that they don't care what others think, mostly to impress others like that. But there do exist people who simply don't care. They know the friends they have aren't so petty to care, either. Of course, these people like everyone else revel in "showing off" occasionally, but there's a difference between simply deriving pleasure from it and either surrounding yourself with those who demand it of you or having an emotional dependency on doing so.

Having used Debian sid as my desktop machine for quite a few years, I'm happy to report that if those were problems you experienced with Ubuntu, they shouldn't be for long.
My iPod (along with other devices) mounts automagically when plugged in, and the program to handle it (Rhythmbox) is opened automatically. MP3 playback (at least for Gnome applications) is dependent simply on having the right gstreamer plugin installed. These are already on Ubuntu as far as I know, so it's probably just a matter of making it installed in a default desktop installation.
Using Gnome, I don't know about the issues you experienced with Konqueror being slow, but Nautilus is fast enough that I don't ever think about it. Although, I do still usually go to a console to navigate files; it always feels quicker.
Debian remembers the system volume properly. I think this is simply a matter of having alsa-utils or alsa-base installed. So, for Ubuntu, they should only need to install it by default.
Slow boot and difficulty of package management are still problems that we need to work on, but those problems are having a lot of time and attention paid to them.
The cluttered UI feel is probably, in my opinion, simply due to using KDE. I've never held their UI design principles in high esteem. I think when I realized that the clock applet had four fucking panels of options, I was put off the most. Gnome feels quite well-organized and, although supposedly more sluggish than KDE, not so much that the average user would notice. Remember, many of them would be coming from spyware-infested Windows machines.
The others I'd have some mild commentary for, but I have other things to do.:)
I take MARTA (Atlanta transit) into school every day. Once, I had to use a station I'm not familiar with. I normally have an impeccable sense of direction, so I get up on the platform and go to the "Southbound" side. I zone out, the train comes, and I hop in and open a book. About 15 minutes later, I hear the conductor say this is the last Northbound stop, which makes me do a double-take. Even returning to that station later in the night, and trying to figure out the direction I'm facing based on how I drove in there, I still can't understand how the poles "feel" reversed in that area.

Make a.porn folder in your home directory (Hey, real life scenario). Make a pictures subdir, and inside that a few other dirs (teen, goth, whatever you fancy). Now populate those directories with pictures, then try getting to them with Eye of Gnome.
So let me get this straight. You want a hidden.porn folder that...isn't hidden? What's the point of making it hidden if anyone viewing a directory tree can plainly see it?
Hidden folders aren't intended to be some kind of spousal security measure, they're there so that configuration and system files can be placed somewhere without cluttering up the important files you made. If you want to hide your porn from a spouse, encrypt it or simply use a different user than she does and remove all permissions except for you.

And when I say education, I mean education. I don't mean "teach abstinence". I mean "this is sex, this is what goes on, this is what you can catch, and this is how you can do it safely." I'm talking a significant course here, not just a day out of gym class. Fuck, this is probably the most insightful comment in the entire thread. I don't know about you guys, but seeing some of this stuff is more than enough to keep anyone's hormones in check. Ever see a grunting, screaming woman giving birth?

I really like the show. I'd watched it sporadically whenever I saw it was on for several years, but just before season 7, I started torrenting the previous episodes, and watched them all in sequence. The first two seasons were alright, and it started picking up new and interesting story arcs in seasons 3 through 5. Six felt a little rehashed, and seven picked up with Anubis. Eight is where it legitimately should have ended, with the destruction of Anubis and the ending of virtually every side plot.
With that said, season 9 actually surprised me with how well they managed to do, even with Richard Dean Anderson leaving, Don Davis being gone, and Amanda Tapping out of commission for a few months. Ben, Beau, and Claudia didn't feel right at first, but I gradually came to like the direction the show took; and at least there's always still Daniel and Teal'c. Plus, the Ori have been a pretty damned interesting new enemy. However, I'm glad they're cancelling the show. I'd rather them finish the Ori story reasonably quickly and end the show on a moderately high note (probably not as high as season 8, but high nonetheless) rather than dragging it on and on. While it's commendable how they've handled the transition to the new cast, it's not something that can be kept up indefinitely.
At the risk of sounding like a troll, is this not a sign of how far behind the rest of the Linux world Debian has let itself fall? An installation GUI touted as a "major new feature"?
Actually, this is a pretty reasonably significant step forward. Debian lacked a good installation for a long time, simply because of the vast number of architectures it supports. Debian-Installer was written from the ground-up to support all (eleven? thirteen?) architectures that Debian supports, plus provide hooks for CUIs, GUIs, and scriptable interfaces.
While the current iteration of the graphical installer only works on AMD64 and x86, it's only a matter of time before it's supported across all capable architectures.
Also importantly, Debian has finally gotten this done "the right way", in that there aren't any significant hacks to provide nice things like accurate progress indicators, etc., that other graphical installers have used.
And no, I can't think of any other Linux distro that has "caught up" to Debian in terms of packaging. Debian comes with over 15,000 packaged libraries/software, which is a shiton more than other distributions offer (Ubuntu excepted, for obvious reasons). Not only that, but there's simply no comparison between yum and apt.
Science doesn't find facts; it interprets them. It builds models which try and closely predict other related facts (which require independent verification), but never does it directly find them. As an example, our understanding of gravity and the warping of spacetime could be (and probably is) entirely wrong -- simply a shortsighted attempt without enough resolution in our data. But it doesn't matter: for the things we're currently trying to predict, it works within an astounding level of accuracy. Trying to reconcile its differences with quantum mechanics will undoubtedly lead to a completely new understanding of reality (e.g., string theory). It will be wholesale replaced with a new interpretation of our universe, but in no way is its predictive power lessened. It's simply an incomplete view.
I believe the reason this would "work" is because they're looking at general models. Current methods of weather forecasting let us predict small pockets of weather with acceptable accuracy. What these researchers seem to be trying to do is try and generalize over a larger period of time. Although weather forecasts aren't able to determine "City X will have scattered showers and a temperature of X degrees Fahrenheit" past a two-week threshold (or so), extending the time to decades may still allow us the accuracy of saying "80% of hurricanes in the area will strike the eastern coast of Country X, and 10% of them will have winds exceeding XXX MPH".
If I were to put together a high-end machine right now I would certainly throw in at least 2 hard drives. A very small 10RPM drive for the OS, programs, and a much larger (but probably slower) drive for storing all my files.
And you would be making an extraordinarily silly mistake. The OS is loaded from the disk at most once and stored in memory. Data is accessed over and over, giving a *much* better increase in performance if stored on the faster drive.
