"Why's that guy stealing on the tv?" and you explain that stealing is wrong and he'll eventually be punished for it.
Oh. I thought the lesson was "Son, if you kill the whore afterwards you'll get your money back. And oh yeah, use the baseball bat so you'll save the bullets for when you're in trouble.".
I think the difference in speed you are referring to is that the Russian seat is measured in kilometers and the US seat is in Knots. The Russian design is rated to about 1400kph, while the US design is 600 knots. If you do the simple math, that doesn't make them equal, until you realize that 600 knots is much much faster at altitude (because of air density,) where kilometers is a fixed distance. 600 knots at sea level is about ~1100kph, but at 35,000 feet, it is ~1400kph.
Eh, what? A knot, per definition, is nautical miles per hour. The length of a nautical mile, again per definition, is 1852 meters, regardless of altitude.
Now, while I don't know about ejection seat specifications, it certainly sounds reasonably that the operating envelope would be given in terms of indicated air speed, rather than true air speed. But this is a different issue than whether the speed is given in units of knots or kph.
BTW, while I was doing some quick research for this reply. it seems that NetBSD is about to drop Soft Updates in favor of a physical block journaling technology (WAPBL), according to Wikipedia. They didn't get a reference to this, nor did they say why NetBSD was planning on dropping Soft Updates, but there is a description of the replacement technology here: http://www.wasabisystems.com/technology/wjfs. But if Soft Updates is so great, why is NetBSD replacing it
While I'm a Linux user myself, I also happened to stumble upon this while surfing a few months ago. IIRC based on some blog and mailing list posts I read at the time, the fundamental problem with soft updates on NetBSD (or soft dependencies, softdeps as they call it) was that they could never get the code stable enough for production usage.
Or to put it another way, soft updates work on FreeBSD because McKusick himself maintains the code.:)
I believe GFS uses a local fs on each node to take care of, well, all the stuff that a normal local fs like ext3 does. GFS only does the distributed stuff on top of that.
Updating in general went completely pain-free. Well, except for the servers time-outing when I tried to update on the day of the release, so I had to postpone one day.
Fonts were ugly in the beginning, turned out to be due to an old ~/.Xresources I had lying around that made my apps use the old X core fonts instead of fontconfig. No idea why it previously worked fine on 9.04. But nothing I can blame ubuntu devs on really.
Some OpenGL apps such as google earth flicker when using a compositing desktop. This is apparently a fundamental problem with the existing DRI architecture. Solution is to switch to DRI2, whenever that is ready. Again, not Ubuntu's fault really.
Improvements:
KDE 4.3.x instead of 4.2.x. Boatloads of improvements and bugfixes. And of course, also other updated apps, such as firefox 3.5, emacs 23.1 etc.
Open source radeon drivers can run OpenGL stuff with my X1550 without crashing (9.04 hard locked the machine within minutes).
My father also made a temperature controller for his house, controlling the hot/cold mixer before the water is pumped through the radiators. Inputs were inside temp, outside temp, and boiler temp. But this was all done with analog electronics, recycled from all kinds of crap that fills up his garage.
Personally, I'd have done it with an AVR or maybe even a small embedded Linux system (a suitable excuse to tinker, if nothing else). But hey, it works, so who am I to complain. Took a lot of tweaking before it worked properly though.
Cray has something like this in the XT series. Each cabinet has a single big fan at the bottom, sucking in air from below the raised floor and pushing it vertically through the system. And since there are no hard drives either, that fan is the only moving part in the entire cabinet.
I think newer versions also have liquid cooling in addition to the big fan. Basically something like a car radiator at the top of the cabinet.
Can Sun/SPARC keep ahead of them? They might only be ahead in SSL/TLS. And if that becomes a big enough demand, some taiwanese/chinese company start producing cheap pcie cards to do that
Crypto accelerator cards have been available for a long time. Don't know about the price though.
Or Intel could decide to use some transistors to do it - they have lots of transistors to play with on their chips, it's just a matter of priorities.
See "Sandy bridge", Intel's next 32nm chip, due Q1 2011, will have extra instructions for AES.
That's 1024 Itanium2 processors, or 4096-way in the usual sense as each processor has 2 cores with 2 hw threads each.
With NUMA architecture things can get even bigger
All big machines are NUMA. And nowadays not-so-big as well. Say a 2-socket Opteron or Nehalem system, that's NUMA too, even though the NUMA factor is obviously much smaller than in those big SGI machines.
TFA isn't particularly detailed, beyond saying SSD's are used on "4 special I/O nodes".
One obvious thing would be to use SSD's for the Lustre MDS while using SATA as usual for the OSS's. That could potentially help with the "why does ls -l take minutes" issue familiar to Lustre users on heavily loaded systems, while not noticeably increasing the cost of the storage system as a whole.
MS takes the drivers back to user mode after touting the kernel-mode as a performance plus.
Based on my experience with 2008/Win 7 and ATI, I think the display drivers belong firmly in user mode.
Actually, if anything, the graphics driver models of windows and Linux are converging. The Vista/win7 graphics driver model is AFAIK not a pure user space model, but there is a small kernel component doing stuff like mode-setting and GPU memory management. Precisely like the "new" Linux graphics drivers with KMS and GEM/TTM; the bulk of the driver still resides in user space.
Fundamentally, the so-called "War on drugs" is a world-wide 100 year old failure that rolls on with the weight of a dogmatic belief in its own righteousness and moral panicking. Nobody is saying that being a drug addict is good, but it should be treated like a medical problem, just like alcohol or tobacco addiction. For the long story, see e.g. http://www.economist.com/opinion/displaystory.cfm?story_id=13237193
IIRC at least here in Europe heroin or various derivatives thereof are more popular than cocaine, and from what I understand the reverse is true in the US. Supposedly mostly due to where it's produced; heroin - Afghanistan, cocaine - South America.
Voting methods can be ranked in order of how well the chosen candidate matches the preferences of the electorate; in such rankings most voting systems, including the above mentioned Borda and Approval methods, outperform the current system.
Whether that benefits the population as a whole or not is more difficult to say. Presumably voting systems that give more weight to centrist candidates fare could be better because they would be less likely to cause violent reactions or in the worst case revolutions.
I think the persecution complex is pretty universal in Christianity, fundamentalist or not. I was brought up a Lutheran, and in the religion lessons in school it was apparently very important to know how cruelly the evil Romans persecuted the early Christians. And later on, the same thing repeats, except it's the evil Catholics persecuting us poor righteous Lutherans.
And come to think of it, it's not only Christianity. Remember that Danish cartoon thing? Lots of people were insanely butthurt by that, resulting in epic lulz.
Bottom line, a persecution complex just seems a very powerful tool to create a us vs. them mentality.
Just because a replied to your snarky message with another equally snarky one, doesn't mean I'm not able to put it into words. For instance, a few reasons why I prefer Linux over *BSD or Solaris:
- better package management
- better hw support
- better ISV support
- the uncertain future of Solaris (after all, Sun got bought because they were bleeding red ink left and right, will the Solaris devs escape the inevitable layoffs and Oracle continue pumping money into Solaris development just to try to keep up with Linux?)
- Lack of tier-1 commercial support for *BSD.
- Much larger community
- Better availability of qualified Linux sysadmins
Would would a windows driver be a requirement? I, and presumably many others, currently use ext3 regardless of the existence of a windows driver (such a thing supposedly exists, but I have never needed it). For windows access there is samba, after all (via a virtual machine if it needs to be done on the same piece of HW).
For external drives the situation is indeed slighly different. I typically use either ext3 or ntfs depending on whether I want to access them from windows or not.

Some observations from my brief experience
Updating in general went completely pain-free. Well, except for the servers time-outing when I tried to update on the day of the release, so I had to postpone one day.
Regressions:
Audio occasionally pops; due to some power saving stuff, solution: comment out a single line: https://lists.ubuntu.com/archives/ubuntu-devel-discuss/2009-May/008239.html

Per-thread pools to reduce locking overhead. See the release notes for more details.
According to this picture ( http://en.wikipedia.org/wiki/File:Rational_scale_to_assess_the_harm_of_drugs_(mean_physical_harm_and_mean_dependence).svg , from an article published in The Lancet), while cocaine is more harmful than alcohol & tobacco, it's only marginally more addictive than tobacco. So it's not like you do coke once, and then spend the rest of your life craving the next hit.
Fundamentally, the so-called "War on drugs" is a world-wide 100 year old failure that rolls on with the weight of a dogmatic belief in its own righteousness and moral panicking.

It's already free; it's from last week's LWN weekly news.
Yeah, but those operating systems suck in other ways, so no thanks. I'll get by with ext3/4 and xfs until btrfs is production ready. YMMV.
