Not necessarily. There were a series of orbiting radiometers in the 70s on the Nibmus series sats. (I did my work with SCAMS - SCAnning Microwave Spectrometer on the Nimbus F sat and chewed through around 4000 7 track tapes of data from the NEMS - Nimbus E Mircrowave Spectrometer when I did my PhD on the topic at MIT) These later became the MSU units on the Tiros sats.
The defense department has a number of sats up there in the DMSP program that use scanning microwave spectrometers. Sadly, you are lot likely to get good battlefield weather reports from the locals even if they could given them to you.
A more recent version of these is diagrammed at http://nsidc.org/data/docs/daac/smmr_instrument.gd.html
Its easier because of the pressure broadening of the absorbtion lines to get profiles looking down than it is looking up. The real appeal though is to provide coverage over places where folks do not throw raobs (sondes) up. Thus the orbiting platform is preferred anyway.
You can see the clouds. But it gets hard to figure out what the clouds are made of. Water vapor has a resonant absorbtion line at 22.235 Ghz and liquid water has a broad non-resonant absorbtion spectra (which is wby microwave ovens work). The pressure in the atmostphere broadens the lines, so if you look at one frequency you can "see" lower in the atmosphere than you can at another nearby frequency. The inversion problem of getting temperature and liquid water/water vapor profiles out of this junk is non-trivial. Your visual stuff and IR just sees the cloud tops and little more. IR can get profiles up to the cloud top and then it is a dead stop. Visual does not get profiles period. Since the amount of energy in the atmostphere is in no small measure bound up with the amount of water vapor that is in it, you better see below the tops of the clouds. Without that, a big fat hot cumulus and a cold thin cirris cloud look an awful lot like each other. Optical is useless for detecting sea surface conditions (wind speed). The "brightness" of the ocean surface is a function of wind speed and foam coverage. Of course you would need wind speed for anything now would you? Same thing goes with the depth of snow. Snow several feet deep reflects differently on land than snow 1/10 of an inch deep. Last time I looked, there was an issue of the heat necessary to melt the junk and the runoff from it that was of more than passing interest to a lot of folks.
One of the major problems with weather prediction, besides the non-linear chaotic stuff, is that you have to characterize a pretty rich field of data points before you turn on your finite mesh predictor. Sadly, most of the world does not chuck weather balloons up and/or is covered with ocean. Placing a call to that spot three miles offshore is not an option. Even if it is, you still have to understand much more about what the vertical profile of the weather is above the spot than just a simple rain/no rain analysis.
I dare say, that there is more than a little bit of a problem with what they are talking about. Of course if you care to live in the bad old days of the Galveston Hurricane or the Hurricane of 38, I guess there is no stopping you. But please learn a bit about weather forcasting before you decide that this is fud. It is anything but.
Yep. You got it. We know that every self respecting criminal these days goes through the background check and gets fingerprinted and has their records sent to the FBI. Further, up here you have to also be interviewed by the police department. Apparently that is so that they can get to know their objective when its time to put them behind bars.
Last time we had this sort of crud, they were going to put "taggents" in all the explosives and gun powders so that they could trace them. Yeah right.
About all this stuff has done is to be a major pain in the butt to all concerned. Rather than making sure that nobody brings a gun on an airliner, I dare say we would have zero highjackings if everyone were required to be trained in the proper use of firearms and have a gun when they fly. [ok, ok, a bit of byperbole, turn off the flames]. However, if you are a male in Switzerland, you must re-qualify every several years in markmenship or have to go back to boot camp.
Who knows? M$ is so screwed up, it probably has to do with a buffer overrun... These guys are sad. What is even sadder is that they haven't made a good product of their own since Gate's basic interpreter and Flight Simulator. Everything else has been a reverse engineer or an outright purchase... It just goes to show that for the average person, pathetic is good enough providing you get Michael Dell to cram it down their throats.
I have a couple of terabytes of video stripped from DVDs on disk over a couple of servers. I also have a gigbit ethernet running. I can play any of the videos on any of the other machines wih one of the standard players that accepts input from a video_ts folder. PowerDVD does this on a PC, the standard DVD player does this on a Mac. (And yes the network is hetrogenous wrt machines). You get the menus etc at the machine playing the movie. Since most DVD content is encoded at around 10 megabits/sec or less, pushing that across a gigbit network at full speed is trivial. Even 100Base-T works well enough for all of that.
About the only thing that you have to get concerned with is managing the access to the titles using shortcuts/alias on the machine playing the movie.
Again, I do not see where the problem is. I do what this guy is talking about (sans plasma display) on a daily basis already.
(admittedly, if there is CSS, you have to rip with something that gets rid of it to get the titles to play from the video_ts folders. but you had to do that to play from the mpg files too...)
Is open minds. I have found in my wanderings around the IT world in the companies that I have worked for that there a large number of people who are only capable of rote tasks in a sandbox of M$ products. The concept of being able to generalize from M$ office to Star Office is totally beyond them. Heaven help them if they see a different gui for their mail program. In that case they are totally lost. This is in contrast to folks who master a number of enviroments and understand what happens when they hit return.
I suggest that these M$ only folks are NOT the folks that a company benefits by hiring unless you want an army of mindless drones. Some places may want that sort of person, but I doubt that they are the companies that suceed in life.
The NRA promotes a number of things. gun safety among them.
The MPAA promotes a number of things. Among these are vivid depictions of people killing, maiming, and otherwise behaving in an anti-social manner with weapons. I dare say that there have been more murders, mayhem, and such inspired by products of the MPAA than products of the NRA.
I must presume that this product will also blcok the Department of Defense, The Army, The Navy, the Air Force, The National Guard, The Police, and many other groups that use and train with Weapons. Oh? It doesn't? Well how about that...
This is political hacksterism of the greatest kind and should be shut down immediately. A lawsuit by the NRA demanding damages would be in order.
The Lamp folks appeared on CNBC on friday talking about this. They also said that the software was up at www.mit.edu under one of the freeware licenses. I dare say that if it had just stayed on campus, it may have flown under the RIAA's radar. As it was, somebody felt they had to shut it down before everyone else in the world did it. jmo.
And some usb networking dongles. The mods for the audio out on the i-opener are (were) around on the net. The audio is passable/good. They run off of around 40 watts, so you won't heat up the house or go broke paying the electricity. Use the central machine as a file server.
Alternately, the Via Eden machines do a nice job of this. The nice thing here is that they have enough guts to play DVDs back over the network. (DVD over 10baseT is passable, over 100baseT more than adequate). This was my approach to the solution when I decided that I wanted to stream DVDs off my central repository(s). Prior to streaming DVD content, an I-opener (K6 mod) was more than enough, plus you have the advantage of a small LDC display thrown in for no additional cost.
The Brits have made a total bolix of the electricity market for the past several years trying market deregulation. They have just bailed out their neuclear utility (British Energy) through a series of potentially illegal (by EU standrards at least) loans and subsidies at the reprocessing level so it would not go into bankruptcy. They have managed to bankrupt TXU Europe and are getting close with a couple more like AES Drax (a large coal fired facility in Yorkshire). If AES Drax had to shut down totally, it would seriously destabalize the entire British Energy grid. Nobody in their right, wrong or drunken mind is investing in building new plant.
The Brits have been luck recently. They have had a couple of warm winters. The sensitivity of generation to temperature is 500 MW of generation needed per degree C drop in temperature (if I remember correctly). If the "Big Chill" happens, you will have a lot of Brits sitting "cold in the dark" while they thank the British beaurocracy. California east here we come...
When you walk into the lion's den, you need more than a g-string on. To have put themselves in a position where M$ could grab Sendo's intellectual property by not giving them anything is stupid.
That said, dealing in bad faith is something that is tortous. I hope Sendo recovers the stars the moon and the sky from these bastards.
In the hands of the intellegent, they amplify that persons ability to learn, teach and all the rest. In the hands of the stupid and ignorant, they make for immense stupidity and ignorance. All the "Spice Racks" not withstanding, a good film is made by a good editor who understands what they are doing and what the desired result will be. Same thing with teaching. The concept that all you have to do is to put machines in the hands of teachers who max out at AOL is an obvious fallacy. If you put them in the hands of teachers who understand their field and can teach their field with nothing more than a hunk of chalk and a blackboard they will increase the understanding and depth of knowledge.
Its the basics. Not the ribbons and bows that matter.
IDE drives have a reputation as being substandard. This is actually not the case overall. Most IDE drives are housed in machines on the office or house carpet which is one of the worst enviroments in the world for dust, dirt, grit, dog pee and heat. SCSI drives are often housed in the nice clean, cooled machine room. Further, IDE drives in personal machines go through many, many more spinup cycles than that 24/7 server disk does. Check the MTBF figures, they will also specify a number of spinups figure, since this is where the bearing wear is.
Backup tape bleeds and needs to be re-generated from time to time. It is no answer to the problem. Just ask anyone who has done the "tape salvager" routine on the 9 track. However, the same thing will happen with disks. the thermal stuff will weaken bits, etc. Personally a raid 5 array on removable ide that is periodically re-read to regenerate lost bits is the way to go.
As far as doing the same thing that everyone else does with tape & SCSI, most folks have a lemming viewpoint. They do not like to stick their heads out and put their careers on the line for something that differs with what everyone else does.
DV-R is nice to keep stuff in archive off site, but even with the current price of about $5 for a blank, it will take you $75 of blanks (15 DV-Rs each having 4 gb each) to get the amount of storage that you would get on a 60 gb drive for the same price. Faster access, less time to create the media, etc. Put it in one of the cheap 3.5 inch firewire enclosures, and it will even take up less space than 15 DV-Rs.
Personally, the solution I have gone for is to put together a 1/2 terabyte server on my network. For the cost of $80 for a case, $80 for a motherboard, $80 for a cpu chip, $80 for memory, $640 for 8 60 gb disk drives (at $80 ea), and $80 bucks for 2 more ide controllers, you can get a ~1/2 terabyte server for $1040. Run a Linux and put up Samba and Appleshare for free. Super high performance, not. But enough to do storage of infrequently used files and backup space.

The standard 802.11b usually is preconfigured to be on channel 6. Do yourself a favor, change it when you install your network to something else... The average folks will just plug in the WAP and let it run on that channel. You can have a brain and not compete there.
Convert 100% of your machines to Linux. Tell MS to audit all they want... O, wnd btw if you find any liscences tell MS that you do not agree to the terms and want your money back.
Bill was whining again today that the propsed penalties will change how MS does business. Lets hope so.
2) Take machine of #1 apart, evenly divide parts into two piles.
3) Put enough extra parts into each pile to make a complete machine.
4) Reassemble the 2 machines.
Now, which machine is the origional one? The one that got the hard drive, but not the processor? The one that got the floppy? Or have you just created 2 liscenses since each machine has equal claim to being the origional machine. This posture on the part of M$ is legally dubious, counter-productive and a total crock.
