But he doesn't say anything about a platform agnostic operating SYSTEM. True, he's saying that the enviornment of the future happens to be the one that he personally thought up (is this an article or an advertisement?), but he says that the SYSTEM should be Windows just because it's what most people are using and everyone should just use Microsoft because of that.
I call big BS on that one. The limitations of PC hardware and the Windows operating systems ARE relevant, and as long as I can't write to a floppy drive and listen to an MP3 at the same time, or the machine's default network sharing and mail systems leave me ripe for butt rape by script kiddies, I certainly won't be running this vision of the future.
No, it's not a sign of AOL's demise. A lot of companies are reluctant to use free instant messaging software because they don't have any control over who's talking to who about what, who might be listening in on those conversations, and don't have anyone to talk to on the phone if they have a problem with the instant messaging client. Paying for "secure AIM" lets AIM into the coveted business market by making managers feel secure while giving them a very small benefit over the free service. Plus it lets AOL get money for something that they used to do for free.
It's a lot like how people will rather pay for some software than use the open source version.::sigh::
What's the big deal here? Blocking AIM is a cinch, for anyone who actually cares on examining the problem. Block out the toc.oscar.aol.com hosts and the login.oscar.aol.com hosts on your firewall. Or just 64.12.161.x and 64.12.163.x networks. You'd think this was rocket science.
Clustering Needs and PG county

Ask Donald Becker

First, thank you for the drivers. Everyone else seems to be saying that too, but I guess it can't be said enough.
Secondly, what applications are there out there that you think that beowulf-style clusters are especially suitable for that you don't see people applying them to? Personally I have a mini-cluster for POV-Ray, and I know there's lots of people using clusters for more interesting projects like weather analysis, geographical mapping, and nuclear simulation, but what do you think *isn't* taking advantage of this technology that should be? Is there anything that you feel should be advancing that isn't?
Thirdly (and this is totally personal, having grown up in Greenbelt and a frequent visitor to GSFC), are you dismayed that PG county never did much to take advantage of having such a resource as Goddard's Space Flight Center? Aside from naming apartment complexes things like "Goddard Space Village", of course. Or maybe things like Government pay scales are to blame?
I've always been told when informally discussing force to just say force=mass*velocity because acceleration as a vector tends to confuse the audience, and to the layman it's the same thing. For anyone who cares to look: here's the relationship of momentum to force.
So the formula isn't standard, but the effect of increasing mass to reduce velocity but retain the amount of recoil energy as oppossed to dropping the powder load is still right.
Er, the 7.62x39mm Russian round that's used in the AK47 is an intermediate round, which places it just above pistol rounds in the firepower heirarchy. A.30-06 is almost twice as long and therefore much much more powerful. Of course, both have the same diameter, but that's just part of the equation.
You may be thinking of the 7.62x54mm Russian round that's a little more rare and is used in machine guns and bolt action rifles, which is sort of between the US.308 and.30-06.
Actually, they DON'T decrease the powder charge to make a round subsonic, they increase the mass of the bullet. Force=Mass*Velocity. That way the energy being delivered is the same and the firearm action still cycles properly (if you decrease the energy of the system, the mainspring will prevent the bolt from moving far enough back to cycle the action, and the firearm will malfunction). At least that's the way it is for commercial/military weapons.
But, of course, ANY round you think of probably exists on some wildcatter's bench somewhere, as well as a gun to make to do something you wouldn't expect. Many.45 and 9mm (and.22, and.50, and.30, etc etc etc) silencers use baffles to drop the speed of the otherwise supersonic round to subsonic, and there's no reason a similar device made in anyone's garage can't be used on a.223. There's also no reason that a home reloader can't make an underpowered load and use it in a bolt action or put a silly-weak mainspring in his gun. Saying there's no such thing as a subsonic.223 is silly, they almost certainly exist somewhere.
However, since the whole concept of the 5.56mm as a military round (as compared to.223 commercial) is a high-velocity, high-accuracy round that tumbles when it goes below the speed of sound (resulting in awful terminal ballistic performance, but wonderful energy transferral to a target), I'd have to say that you can't fault the original poster all that much. Guess they weren't specific enough. Then again, it's impossible to be specific enough when talking about guns... no matter what you say someone will always point out that in circumstances X your case Y will be incorrect. Like I'm now doing to you and you did to the original poster.
Noteable also that a 9mm or.45 subsonic will do just as well at going through body armor as they normally do, which is poorly. The energy in the system is still the same as when using higher velocity, lower mass rounds, which also happens to be the amount of energy that a kevlar vest is designed to absorb. Rifle energy loads, either high velocity or high mass, will still usually zip right through them.
AOL had 2.5 million subscribers in 1995 with a high water of about 75k users, a large proportion of which were chatting (especially since high waters back then were driven by auditorium chats). Say what you want about AOL 'sucking'. IRC sucked much worse back then and has not gotten much better since.
Er, whatever else happens, I'd like to think of people with enough skill to be submitting kernel patches (that might be accepted, anyway) are above the "1 0wn j00!!" skill level and know something about different development enviornments. Or maybe I'm on crack.
Close, but backwards. The correct way to do a mission like this would be to send the return capsule/craft/whatever before the staff gets there, so it's waiting and ready. Same thing with all the mining, O2, food, water, etc. Deliver the people when you know they'll have everything they need. Having them wait for the return capsule is a bit dramatic, but really not necessary.
...was that they tried to control the content that they were distributing from day 1. If they had been a generic file sharing service, instead of just music, they'd never have been liable for any damages to the RIAA's members... everything would have been in the hands of the upload/downloaders. Sure, they might have had some weird injunctions/warrants to deal with, but they could have claimed all innocence on what was being traded.
Does anyone have any idea why they did that? It cost them dearly, but I've never understood why they made that distinction. Was it to keep porn off the network? Was it to brand the service? What the hell were they thinking?
I can already see thousands of people who think they're rational typing desperately away at their keyboard in an attempt to stem flames that aren't coming. Sheesh. You're preaching about fire and dousing yourself with gasoline.
Everybody knows that sites cost money, and most people are more than willing to be inconvenienced in some way. If it's handled reasonably, it'll be fine. If it's not, people will leave.
Because he's gay we should question his math? That's not relevant at all. And learn to spell. Sorry, couldn't help that. Guess that wasn't relevant either.
Well, yes, MPICH will run on anything, but you'll still be using an OS that recommends 128-256MB of RAM instead of one that can be used with 8. That's a lot of memory slots that you could be using for your application.
The only way an NT cluster would make any sense is if you already have a license that has a bunch of unused seats on it. If you don't have to pay anything extra, it might be worth the trouble to use NT for the convenience.
On the other hand, this is one area where MS sorely lags behind in software. For a research cluster, you'll have very little in the way of applications and be very, very alone when something goes wrong.
Also, the whole ethos of computational clusters is for performance. You won't be able to compile the operating system with just what you need, tuned to your hardware and processors. You'll also blow memory with a desktop you don't need. This just isn't a good idea for any serious cluster.
Awww, you could be a little nicer here. I mean, this is an organization that routinely takes on the titans of business and law, and if they don't do very well maybe it's because all of us freeloaders out here are long on talk and short on walk. If they had more resources they would take on more cases.
Until then, they take the cases that look like they will have the most impact. Of course, that means that if they botch it, it's going to be a big loss too.
TCL has all of the points above and has been around a lot longer than XML. It's also much faster to parse, and you can even 'precompile' your larger config files to be read into the application as a binary.
It's also very very easy to read and has powerful pattern matching and scripting capabilities.
Command HQ was preceeded by Modem Wars in 1988, also by Ozark Softscape, that was an overhead view real-time head-to-head (modem or serial cable) strategy game that felt an awful lot like WarCraft does now. There may have been little on the building side, but this was *the* head to head game to spawn them all.
The expertise of Modem Wars was used to create Command HQ, which Microprose collaborated on. The eventual result was the 1992 Global Conquest, which was the first four-player network game released by a major publisher"
So say thank you to Dani Bunten for them all, that's where the interface really started:)
I imagine it's in the fashion that's the only way a company like Oracle can conceive of a market with Linux in it... as one where application servers (which is what the comment referred to) are closed and the operating system is open.
Otherwise, embracing Linux would, for Oracle, be admitting their entire business model is doomed.

Why would you want to run Linux x86 when you can run Solaris x86?
Oh, yeah, because it's closed source. Forgot the whole point of why Linux is killing Unix.
Hopefully last weeks report on Slashdot earned them some last sales. I know I bought 2 games when I knew I wouldn't be able to later.
