I've tested a Via C7 (1.5 Ghz) in a load-balancing fashion, and was able to pull about ~800 mbps. Of course, that all wasnt going through the C7, only about 30 mbps was (3 direct route load balancing), but nonetheless. The numbers I've seen say the C7 I have (which has dual onboard gigabit ports) can push about 500-750 mbps sustained over the networking gear I'm using (which is junky). Keep in mind that the _majority_ of consumer gear cant get over 250-300 mbps.
Actually this is a common misconception. The Magnets in an MRI machine are almost always magenetized. The only time they're de-energized is when they have to perform maintence on the machine (and when you get something stuck in it, of course) and, as I've heard, it takes a while to "re align" the magnets, and thus, is avoided at all costs.
Just so you know, their are a _lot_ of reasons for the altering standards... although I dont quite see the point of this one, especially if its the same formula for compression that jpeg is, but if it's using Wavelet compression, it could be a good idea. I often use TIF, JPEG2000, ECW, and others in my regular work, many of those formats most people have never heard of;)
Hah screw other countries, the real question is, what about all the PRIVATE CORPORATIONS that have their own satellites in orbit, or companies that shoot aerial photography (from planes). And by the way, what would they be airbrushing them out of? The only "Government" satellite that is publicly released is 15 meteres per pixel in resolution MAX, so unless the thing was freakin HUGE it wouldnt be discernable from a car or a small building.
I find it INCREDIBLY hard to believe that he would stumble accross machines with no or default passwords at NASA... I work with a group at NASA AMES on http://worldwind.arc.nasa.gov/ that project, and the security on their machines is almost to the point of rediculousness. The forum software they were running on there was exploited by a 1 day old vulnerability that had no patch released yet a few days ago, the server was offline within 3-5 minutes after exploitation, as soon as it was picked up my NASA Security's IDS system. From what I've heard from our NASA counterparts the security guys are very serious and regularly make their lives difficult by firewalling off ports other than 80. Remote access ports would NEVER be allowed through the firewall (SSH VNC etc) unless you were logged in through their VPN.
From what I've seen, I doubt this guy did many of the things he talks about.
If you are the server admin, you may want to try out lighttpd, or turning off keepalive for a bit. I noticed while browsing the site, as soon as you have a keepalive connection, you can download everything that failed to do so (click on pictures and click "show picture") and it pops up instantly (because you have a keepalive session until it times out), once it times out, you have to wait for another session...
Having taken some of these tests, I can totally agree with you... The problem is, you dont have to be GOOD at what you do to get the tests, you just have to be good at memorizing, good at studying. Having an MCSE in no way means you have the knowledge anymore, or that you'd be good in any way at troubleshooting or systems administration.
Why would they just have their own generators? A 1.5 megawatt generator runs about 500k$ US last time I took a look, and I imagine that would be a lot cheaper than utility power...
suffer IE bloat? Firefox already is more bloated then IE. I still use IE, because its simply much faster, yeah, it helps that its preloaded into the OS and such but its just _faster_ than firefox.
You failed to cite some credentials that give your information credence, or even sources.

Actually, I found it quite interesting to learn that needing a "clean room" in HD repair is really a misnomer. Its not a ROOM persay, its more of a "work bench" with a HEPA filtration system attached to the top. This way, it just "cleans" the air and sucks all the dust up, instead of it settling on teh drive. From what I've seen, they cost between 3-10 thousand dollars. (So relatively cheap).

I disagree!... The sun isnt renewable:P Its not like we can pop another battery in and off we go for another million years. Of course, its not like it will run out of energy any time soooon...
What other title would you recommend they use? Its a... *gasp* Beginners guide... and its on... Quantum Entanglement. Shocking that the titles are so similar!
I've been wondering for a while, and maybe someone more technologically knowledge able about optical media can clarify this for me but... Why dont they put multiple read heads in one drive? It would seem to me, having two heads on opposite sides of the discs reading like a RAID array would (stripes), would be 2x as fast (so put 15 more heads in there and bam!) same for CD/DVD-RW...
I'd love to have my 500x DVD-rw:P
Considering the maximum bandwidth for HDTV media is 19.4 Mbps as seen here: http://www.crutchfieldadvisor.com/ISEO-rgbtcspd/le arningcenter/home/tv_glossary.html (under bitrate), 27 MB/sec would be more that adequate being 11x that maximum. Of course, it WOULD take 3.16 hours to write a full disc.... but I'd bet this tech is only "testing" phase. (Unless of course the gp mistyped and meant mbps where he put MBps, then we're all screwed)

Yeah, it looks like its running a _lot_ faster, is it still under the same load?

Too bad your first post is Eigth...
They didnt write all their own software, they used NASA World Wind (http://worldwind.arc.nasa.gov/ as well (satellite / aerial imagery viewer).
*ahem* I'd like to mention that google didnt "build" any such 3d mapping tool, rather they bought out keyhole.

Unless of course, where you say you went, is right next to a cell phone tower. Then they know your guilty.
