That's why Cisco's LEAP uses per user WEP keys that are rotated at a user defined interval (the default is every couple hours I believe). Add to that TKIP which ensure that playback attacks can't be used (it hashes the packet with the time and attaches the hash) and Cisco's implementation is pretty darn secure. For the most paranoid of customers they still recomend vpn concentrators between the wireless and wired lans but I personally don't see much use for em in 90+% of installations.
unfortuantly the unavailability of replacement mobo's is not unique to this manufacturer. We had a couple hundred new IBM T-30's when they were very new and of course one died soon after arrival, I ordered the part and the first one they sent was the wrong part (no encryption chip) and then I had to wait 3 weeks for the correct board. This is just the way things go some of the time.
But I have recomended their desktops to quite a few people now that I am no longer in the whitebox business. They seem to actually get it. They balance HDD, graphics and ram nicely (unlike many OEM's that will STILL include 128MB or ram on a system with a 64MB video card and then charge you an arm and a leg to upgrade it.) So far no complaints from any of the people who bought em. In fact if I couldn't beat their prices using newegg and a free OS I would probably buy my next pc from them.
ok subtract one 9, one in a million. I'm a sysadmin with backgrounds in support, programming, and electronics, there aren't many people with more knowledge of computers. This is not bragging, simple fact, most people wouldn't want to know as much as I do. Yes there are a lot of people on slashdot that might but they are a very small % of the worlds population =)
What decrepid version of windows are you using that can still sys a floppy???? All modern and usable flavors of windows can't do that. I keep a compressed dos 7 boot image from Micron around for those times when I do need DOS but I don't think I've used it in over a year (and I worked in desktop support until very recently so I'm as likely as anyone to need it)
A) Microsoft is irrelevant if they are specificly looking for OS solutions B)MS is already admitting that they are pricing themselves out of all but the largest of mid-tier client. C)There are at least two OS products in this field that have been linked to quite a bit in this discussion thread.
I know more about computer systems than 99.99999% of people yet I think I have consulted manuals proper about 5 times, mostly man pages. The rest is gleaned from web pages or just poking at the software.
The vary fact that the cellular phones connected and held a conversation disqualifies that theory, radio waves were going in and out. And they would be coming in at nearly the same power regarless of if there were cellphones on in the plane or not, cellular antennas are pretty omnidirectional. Any frequency occupied by communications equipment is going through the plane at aproximatly the same levels regardless of whether there are transmitters on board (towers are much more powerfull than handsets).
Documentation isn't for the silly users, its for the poor sap that has to maintain your code =)

because there are high range details dropped by both lossy encoders that CAN be heard by some people, I have heard them in some situation myself even when giving the encoders a basically limitless bit resivoir (Lame extreme and Ogg Vorbis highest).
ok if the pretty pictures dont convince you how about the largest blind listening test done by C't magazine which placed AAC dead last at 128Kbit ? Yeah it sucks worse then wma and mp3 at that rate, which quincidently (sp?) is the rate at which apple is distributing these songs.
Because of design by contract the code is pretty much self documenting.

if you can hear any dropoff of information in a cd then you are superhuman because studies have been done with audio engineers using blind tests between DAT and cd and not one could consistantly pick one over the other. There are advantages to DAT going into post production but for listening there is no difference between the two, 44.1Khz PCM is good enough to reproduce sound for 100% of human ears.
actually check out the graphs for the HD 495 and the SR60, the Sennheisers are better, and I like open cans so for me they are infinitly better =) Trust me I did my homework, both on the technical end and on the listening test end.
Umm how is that any different, the towers or AP's are doing the same thing, communicating with a bunch of clients that are wissing by at high speed. The AP's have to deal with clients switching every hundred feet or so on a train that is many hundreds of feet long, so they have to have to talk to many sets of clients in a short amount of time without properly tearing down the connection (wifi roaming does not update the roamed from AP). Your phone might go schizo trying to keep authenticate to the providers network but cellular networks don't keep a circuit or bandwidth slot open for every client talking on the cell, the networks would never work if that were the case.
The crashing of the cockpit door just before the plane plunged into the mountainside in PA was pretty easy to hear on the cockpit voice recorder. This was the FBI's conclusion and the conclusion of most people who heard the tape. Add in the one passenger telling his wife that they were going to do something about the situation just moments before and you have a pretty solid case.
Because all your admin's are linux people and a port like this allows them to run one standard environment on basically every piece of hardware in existance?? Linux was already on its way there with native ports to most of the popular architectures, this just speeds it up a bit.

The encoding process is lossless from the source, aka there is no loss of information from the origional to the copy. Basically the lossless encoders are specialized version of encoding schemes like those that power gzip, zip and rar.

what mp3 encoder did they use and what settings? mp3 encoders are so incredibly different that they might as well be different formats. LAME and Fronhoffer are in one set and then there are the ok encoders, and finally there are the Xing's and such that just don't produce listenable results at any bitrate.
This was NOT due to the cellphones in the planes, more due to the overloading of the networks due to call volume. The POTS network was also similarly effected so it wasn't just wireless technology either.
Well the much simpler switching methods used in wifi work fine at speeds in excess of 200 mph, the shinkonsen (sp?) has a test going using AP's every couple hundred feat and it worked fine with all but the crappiest of cards. This was using Cisco and Breezecom AP's others may not do so well (btw this fast switching speed was pushing the authentication architecture to the max but it did work after some minor tweaks)
The fact that you think cell phones use differentiated frequencies to distribute load shows you have no clue how the encoding schemes work. There are only a handfull of frequencies per carrier, but they support thousands of users. Yes the renegotiating will take some small % of the available bandwidth but not considerably more than driving around and switching cells. Trust me I worked with guys with phd's and 30+ years in telecommunications implementation, if they tell me its a bunch of hogwash I believe them =)
How about using a media player that supports all formats and just playing them that way, no need for a cd. That's how I did my A,B,C testing with Lame mp3, OGG Vorbis, and PCM wav.
Every Nextel I've had the displeasure of owning has done this. They also eat batteries like nothing else, even if you aren't using direct connect (I was the only employee in my megacell for one company so no one to message with) they have standby times of a couple days max =(
