Snicker. Mainframes don't even have the concept> of what video cards are, much less sound cards.
After all, you can't even plug a terminal into a mainframe.
Backups and disaster recovery is something for the operators (they're not called administrators).
And the System Programmers and Operations Managers who buy packages like Fastpath and Harbor NSM.
If applications themselves are stable, it's probably a result of COBOL being a straighforward procedural language without all the trickiness of C pointers.
Thank $DEITY I'm not the only person to think so...
Now as far as security, I'd say mainframe security is 99% security by obscurity. The mainframe programmers I know are hopelessly naive about network security policy, basic things a Windows or Unix admin would know from working in a hostile environment like the Internet. You know, things like password policy, IP networking, etc.
How many black hats can get into a mainframe, anyway, and know the mainframe utilities?
Until these I wanna be UNIQUE, so I'll mutilate myself because I saw other people do too twits realize that they are followers just like the "popular kids", they won't be an different from the kids who fawn Paris Hilton, Britney Spears, Lindsey Lohan, Hayden Christensen & Orlanso Bloom.
"Stopping Power" doesn't have to do with kinetic energy, it has to do with stopping the enemy from attacking you. A determined enemy can often take two or more 9mm/.38 rounds before they halt the attack..45 rounds are larger and do more damage, therefore an enemy stops attacking faster.
The weapon originated in response to problems encountered by American units fighting Moro insurgents during the Philippine-American War. The then-standard.38 caliber (9.65 mm) revolver was found to be unsuitable for the rigors of jungle warfare, particularly in terms of stopping power. The Army briefly reverted to the.45 Long Colt revolvers which had been standard during the last decades of the 19th Century; the slower, heavier bullet was found to be more effective against charging tribesmen.
Interestingly, I just saw an episode of Mythbusters where they fired various rounds at a 150 lb pig carcass, hanging from a hook, and that thing did not even move an inch...
I've always imagined a large oxygen-filled vessel (for instance a starship) exploding would send the oxygen flying in all directions (a gas fills its container right...) therefore if the sound could travel through the oxygen anyone in that oxygen could hear it?
sound "is an alternation in pressure, particle displacement, or particle velocity propagated in an elastic material"
The atmosphere at sea-level (and presumably also in the [miniscule, compared to the volume of space] spaceship) is 14.7 psi. There are enough molecules in a cubic meter for it to be considered an elastic material
While the oxygen is being vented into space, there will be (lots of!) noise, but once it's in the never-ending expanse of space, the psi will drop so low that the molecules won't be in close enough proximity to pass on their vibrations.
Vaporising the solid core (if it can even be vaporised at all at that pressure) wouldn't change the fact that there's a massive ball of gas in your way. What makes you think that superheated hydrogen would be flung towards Yavin IV?
Presumably, the planet killer weapon has enough energy to heat the core and the liquid (since the pressures are so great down there) hydrogen so hot & so quickly that it blasts out into space in all directions, including Yavin 4. At least, that's how I imagine it.
Even if it were, why would the atmosphere explode?
Hmmm, let's see. The 3 things necessary for combustion are:
fuel - hydrogen, for example, being flung out from the planet, because the planet killer weapon super-heated it to such an extent
oxygen - like on the surface of Yavin 4
heat - supplied by the planet killer weapon, and transferred to the now-superheated hydrogen.
Looks to me like a recipe for disaster.
Do you see the entire planet catching on fire every time you strike a match?
Don't be dense.
But, since this is/., since a "regular" match burns some of the atmospheric oxygen, a big-enough match would consume all of the atmospheric oyygen.
Gas giants may still have a rocky or metallic core--in fact, it is expected that such a core is probably required for a gas giant to form
Besides, think about the huge amount of superheated hydrogen that would get flung towards Yavin. As soon as it hit the atmosphere, it would explode, consuming lots and lots of oxygen.
If the heat didn't incinerate the rebels, they might asphyxiate from lack of (enough) oxygen.
The reason I found it so funny was because I had the *exact* same discussion of this plot hole with my friends when we were last watching Star Wars
In deep space, you have to aim the parabolic antennae at the destination. Presumably, "subspace" transmissions would behave the same way.
Thus, all the Star Destroyer (or whatever) has to do is notice which direction the antennae was aimed, and go That Way.
How do you miss an enormous plot hole like that?
It's called a plot device. It's also why laser cannons aren't radar controlled, like the CIWS in service since 1979, the AMRAAM, in service since 1991, and the AGM-84 Harpoon, around since 1977.
Oh, and don't forget heat seekers like the AIM-9 Sidewinder and IR targeters like the M1. Abrams, since 1980.
There are more, and I've not even mentioned non-US systems, but you get the picture.
And how can we forget Noise In Space? Just tonight on SG:Atlantis, when a ship blew up, you could hear the explosion on other ships.
What ever happened to, "In space, no one can hear you scream."?
I wonder how many of them are related to enviromental issues? I've read that some of the most frequently used climate models have some serious problems(IE they're unstable in the long run, and tend to run hot over time no matter what the initial inputs are).
This is an extremely important point.
How does anyone know what the more subtle biases in any really complicated model are?
How do we know what the political/moral/philosophical biases of the model creator(s) are?
What if the "guy looking over their shoulder", or more importantly, the guy signing the model builders' paychecks has a strong political/philosophical bias, and the builders incorporate it in subtle ways into the model, to keep the boss happy, or the grant money coming?
It's a good point, but for the multimedia stuff that Mac does best, MHz still matters.
For example, any Anandtech P4/eMT64 vs. AMD64 comparison will show that AMD64 is faster at everything except audio & video compression (even with the new A64's that have SSE3).
And if you have processes running and listening on ports that you don't want or need, why are you running them? Because the operating system that you run is incapable of turning them off, and no other operating system is compatible with a mission-critical application or hardware device?
X Windows uses the 6000ish ports.
Are you telling me that I should not run X Windows?

You're absolutely right. But bigger rounds do have better stopping power.
Why the US Army got the M1911

Interestingly, I just saw an episode of Mythbusters where they fired various rounds at a 150 lb pig carcass, hanging from a hook, and that thing did not even move an inch...
I don't think that's right. The IDF (Israeli Defense Force) puts a big premium on survival of individual soldiers.
He should have said western armies, but 1st world is adequate.
Israel counts on both those metrics.
More appropriately IMO, it's countries that are rich enough to be able to put a high premium on the survival of the individual.

Would bits of former spaceship hitting your hull sound like an explosion?
I don't think so.
An explosion is more of a BOOM, whereas something hitting your hull would be impact (BAM! CLANG!) sounds.
Besides, when the Daedalus blew up the hive ships, it's Asgard shields were at full force, and many dozens of meters from the hull.
Thus, the debris couldn't get to the hull in the 1st place.

Bzzt. No sounds in a vaccuum,but space isn't one.
It's enough of a vacuum that "explosion sounds", i.e., the shock wave transmitted by vibrating molecules, can't occur in space.
It'd be quite possible for sound to be transmitted in the detritus from, say, an explosion.
Those would be the sounds of the detritus smashing into the hull of your ship.

Why shouldn't they?
Face it: Intel is playing a dirty trick that would be legal if it didn't have such a huge market share.
No, no, no.
The issues are:
Thus, nobody except supercomputer geeks has any need for it.
(VLIW fits vector processing like a glove, and the Itanium2 Madison has some very impressive floating point specs.)
they decided to go the cheapest route
Tell us again why doubling the number of registers (which is what AMD64 does in 64-bit mode) is such a bad thing?
Remember, AMD didn't do what Intel did in 1985 and just strech the registers, without adding any.
MS-DOS was (mostly) a clone of CP/M.
v1.0 was a CP/M work-alike at the API level.
IBM rewrote it for v2.0 (because they didn't trust MSFT), adding in all the stuff we greybeards came to know and hate.
Sorry if Im too young to fully understand the joke... But what was the 4 bit processor MS-DOS was written for?
"4 bits" == 50 cents.
So, besides the "decending powers of 2" numbering system, the joke implies that that the 8088 is cheap, and therefore sucks.
Nice troll.

Hmmph. If anything, I'm an AMD fanboy. All my home PCs use Athlons.

Look at the Windows Media Encoder 9 benchmark and see that of the CPUs that "normal" people can afford, the P4s were faster.
But, now that I look at it again, I see that the numbers were's that much better.
I guess my info is out of date...
"We are looking at using some chips from AMD."
It's a good point, but for the multimedia stuff that Mac does best, MHz still matters.
For example, any Anandtech P4/eMT64 vs. AMD64 comparison will show that AMD64 is faster at everything except audio & video compression (even with the new A64's that have SSE3).
Improvement rates tend to slow dramatically as the product reaches the "good enough" point.
For me, that point is Win2k and Office 97.
For my purposes, Win2k is an extremely stable desktop OS, and Office 97 is adequate. In Outlook, threading and filtering would be nice though...
GNOME 1.4 was really nice, but I like v2.10.
And if you have processes running and listening on ports that you don't want or need, why are you running them?

PowerPC in Apple, SPARC in Sun, and now MIPS in SGI...
Don't forget the DEC Alpha. Fastest CPU all thru the 90s.
