To clarify, the probability of detection (POD) measures whether a tornado that occurred was predicted. In other words, was there a warning issued before the tornado touched down.
I'm a meterologist, not computer dude. But my guess is that since the software was already written in a unix environment (HPUX), choosing Linux made it the logical choice.
Well, to throw one stat out at you. In 1987, the NWS had a probability of detection score for tornadoes of 25%. This past year it was nearly 80%. Now given, part of that improvement is better trained employees and an excellent skywarn/spotter network. But yes, bigger and better computers are helping to improve the NWS mission.
I'm a NWS forecaster. We have our new workstations... they are pretty darn nifty. They are dual Xeons (2.4 ghz) running RedHat 7.2. These are much improved over the old HPs, which were J200 (overview). The bad news is that the database and application servers are still the old HPs. These are scheduled to be replaced in the near future as well.
The equations are solvable and they are accurate. It's the garbage in/garbage out that results in the inaccuracies. Can you accurately give the initial conditions...in 3-dimensions for every cubic millimeter of the Earth's atmosphere? Then do you have the computer power to compute to that type of resolution?
Nope. So you do the best that you can do, with the technology at your disposal.
Could some fine ex-Atari employee please release the ROMs for Marble Man (Marble Madness II), so it could be emulated for the PC? I don't see any reason to withhold the ROMs at this point in the game. I can't see anyone profiting, etc.
I thought 1 kilogram equaled the mass of 1 Liter of distilled water. Also 1 Liter of water was what filled a 1 cubic decimeter container. If that's true, why can't we just use these as the standard.
Another thing to note is that gravity isn't constant as you move about the globe. If you are on high terrain over high density rocks, then you weigh more. If you are over the ocean where the crust is thin, you wiegh less.
Unrealty uses the Unreal engine to mainly display commercial real estate. This application could easliy be used for other 3D modeling purposes as well. I believe it uses the Unreal Tournament 1 generation of the engine.
There is a variable within the main Unreal ini file that lets the server admin determine how many UDP server queries per second to allow. Unfortunately this variable is set to unlimited by default. Can't think of this variable off of the top of my head.
That makes sense. I'm sure these guys did a bandwidth budget based on the work that they would be doing. If they could of gotten away with a smaller SCSI array of hard-drives at a server, they would of saved a few bucks, probably around $20k. It also would of been more reliable, considering IDE tends to go bad more often than SCSI. I'm sure they took that into account also.
Do you need a hard drive in each node?

What is the advantage of having a hard drive in each node. Can't you boot each node off of a networked image and load the OS and whatever "work" into memory.
I saw a BattleBot maker with his bot on The ScreenSavers. Gary Coleman of Diffr'nt Strokes fame was part of the Bot's team. A foreshadowing? I think so.
Laptops are more pricey. They don't have horses to run the newer high end games. I agree, laptops are coming down in price, and the graphics chips are only a generation behind the desktops.
I read this on forum so take it as speculative...
SiS651 chipset/962 southbridge
Integrated USB2.0, 1394
2 DIMM DDR200/266/333
400/533MHz bus support
6 Channel CMedia hardware audio
"Heat Pipe" fan duct for processor
Choice of two or three case designs
1 AGP slot + 1 PCI slot
Same case dimensions as the SS50
The price for the bare-bones will be about $360US
Available starting in mid-June?
The onboard video of the SS50 has been reporting similar benchmarks to a Geforce 2MX. SIS has come a long way, and will soon be in direct competition with nvidia and ATI.
In addition, an updated version of the SS-series will have an AGP slot. The AGP version is tentatively planned for the summer. Stay tuned.

Yep, we have some 90 lb. paperweights at our office. The OS has been wiped from the hard drive. Is their a linux flavor that will work on a HP J200?

Fileshack is just as bad as FilePlanet, sorry.
Thanks for hearing my plea...

How about getting a 256-bit 9500, modding it over to a 9700, then overclocking to 9700 pro. So you are getting a $380 part for $160.

Where is the free download. I want the iso files. Thanks.
On my SS51, it couldn't initialize the USB2.0 ports and running x-setup resulted in a bunch of wingding ascii characters.

The Shuttle SS51G cube has its own bag. Some clothes along with the wires, keyboard, mouse, etc., are thrown into this bag.
That's the "keep it simple" method.

How do expect to have a healthy immune system if you don't exercise it with a little bit of bacteria.
And the follow up to the SS40 will be the SS41, with an AGP slot (SS40 doesn't have one).

The Shuttle competitor for this unit will be released in June/July, called the SS51.

No, this start up would pay the Weather Service to attach stuff to their weather balloons, saving the tax payers money.
