The U2 went for this, and it didn't work for long.
It would be high enough to avoid the 'portable' launchers. Sure, the Russians can knock down something that high, but...
I'd guess Iran would have the Sayyad-1 or something along that line of thought. It has a flight altitude of ~66,000 feet and the blimp is going to fly at ~65,000 feet. Just in the envelope, but *that* is a serious rocket - not something that can be just launched from the back of a truck. You would probably use this over airspace you more or less controlled.
Compare that the Preditor, which hits a ceiling around 25,000 feet. A much easier target.
Same deal, IMHO - just another drone. This one with a bit better altitude. You could bring it down, but this is just another cheap, unmanned, long duration surveillance platform. Bet the SAM setup to bring it down, which would get one shot off (if they could get it set up...) would not be worth the cost/benefit ratio.
Every country has their own special sets of law. Saw this when the shop I worked at branched out from the US to EMEA. Every country we sold into, or even better - opened an office - had a unique set of laws. Learned some hard lessons by not using 'native' lawyers. When we did they were not cheap. This was just a contest, right?
The article tried installing Windows 7 on a single hardware setup (a thinkpad) that failed, and that's where the "oh my goodness, how can Microsoft expect all these businesses to upgrade from XP to Windows 7, it's not going to work on pretty much ANY hardware" came from. (Yes, exaggerated)
Erg.... actually, a thinkpad is a *very* common laptop in the cooperate world. The other bit is I'm sure they will add some special sauce to next cut of Active Directory that will require Windows7. They did with XP pro, did again with Vista business...
Would have been nice to see a link to the King Kong defense. Short version - the person uploading the files could be named King Kong for all they knew...
Coherence gives you all the magic you would want to have were you starting to put together high powered hashmap. Does key/value pairs, across multiple machines, with cache invalidation, etc. It also lets you perform interesting queries on the cache. It also can front end hibernate or other databases and act as a cache there too. It also works better than then most http session stores. It also.... Gah. This is one of my favorite JARs in my toolkit.
I've got one. Registered ECC is not supported. Unregistered ECC is supported. I saw no real performance decrease in simulated vs real ECC RAM. The SATA interface seemed to be a much greater bottle neck.
Wish I could.... Many of the current motherboards have an 8G max, so 4x2G is all the RAM you can stuff into them. For those who don't have the system RAM to spare for a ram disk, it is another option.
I've got one. In practice, it is. You cut power to the device, it will start making a backup using its internal battery - which lasts 3-4 hours. This is not dependent on you pushing the button to do a manual backup of the current drive image.
Same as any HDD - a hard shutdown. The battery pack will then start backing up the current state of the memory to a CF card, so that when power is returned to the system you can run fsck or chkdsk. If you don't have a CF card, it will keep the RAM alive for a few hours, then all is gone if power was not restored.
I got one of these in our lab, and can answer questions on it. Had both units... the 6 slot version and the 8 slot version. This thing is the spiritual successor of gigabytes's iRAM. It takes bog standard DDR2 RAM as storage and lets you connect it as a SATA drive.
A few of the things it improved on the old iRAM.
*DDR2 supported ram, with 6-8 slots, taking up to 4G sticks. *A fair sized battery. *A CF backup slot. *RAID friendly, multiple SATA ports on 8 slot model. *Uses 5.25" bay rather than PCI slot. *ECC
First off, no special device driver was needed - the drive was OS agnostic. Every mainboard and controller card I used saw it the device like any other SATA hard drive you might plug in.
The RAM slots take bog standard DDR2 RAM. The documenation mentions speeds of 400/533/667/800 are all supported. Benchmarks with 533 and 800 grade RAM produced identical benchmarks, so faster RAM does not appear to have any impact. I also mixed and matched faster and slower DDR2 modules without issue.
Just like most mainboards, the RAM needed to be installed in pairs if over one stick was used.
Unbuffered ECC or non-ECC modules are both supported. Registered RAM was not. I tried to pull eight 4GB sticks from one of my Sun boxes to give the 'full montey' test. No joy. Had to stick with the far cheaper RAM.
There was an interesting option for these who wanted to have ECC but used 'regular' non-ECC RAM. Eleven percent of the memory could be reserved for error correction. Again, all hardware based - just move a jumper. Performance metrics between ECC and 'simulated ECC' had negligible differences.
The 8 slot model has two SATA ports. By setting a jumper, you could have the entire RAM capacity as one large drive on one SATA port or split it as two independent drives. If you splid the drive you had to have an even number of RAM sticks installed. Another jumper would dumb the interface down to SATA1 speeds rather than SATA2. Never tested that....
Did test RAID-0, however. (grin) The synthetic benchmarks don't hit this device's sweet spot - database usage. Reads are fast. Writes are just about as fast. The RAID controller really makes a difference, as my 3Ware card performed significantly faster than with the mainboard based RAID. Using a EVGA 780i mainboard, it was not crushingly faster than a trio of velociraptors.
For anyone who has installed XP, you know the wait between hitting the 'workgroup' and the first reboot? Just over two minutes. By far the fastest install I've ever done. The OS also started faster than any other disk or SSD system I've used.
The CF bay was a nifty option. The question came up - what if I want to shut my machine down overnight? You can. If you have a CF card with more capacity than your RAM, it will back up the disk image automagically. You can also push a button to back up the current 'drive image' to CF, and another to restore the image. (I was able to go back and forth from Linux and Windows very easily).
Anyhow, tis a fantastic high speed scratch disk or OS disk when write speed matters. For those of us who already maxed out RAM, this covers the gap between RAM drive sharing RAM with the mainboard and fast disk.
I'm sorry, but the days of spending $60 on a game that offers 3-5 hours of gameplay is right out. After the Doom 3/Blue Shift fiasco, I always wait to hear what other *gamers* who actually shuck out there own cash think of it.
Mirror's Edge got heavy, heavy promotion. Heck, thought I even saw an advert for a TV show tie in? People got it and reported how short of a game it is. $50-60 is too much. Strong game with no content -- the studio should not be shocked that it does not sell once word of mouth gets out.
I was curious to see what was in my file, as I've had a devil of a time trying to come up with my travel via stamps in the passport. The airlines were not helpful past 2005. I sent in for mine, based on the notes in that article, like this...

NW., Washington, DC 20229 January 6, 2009
To: Freedom of Information Act Request From: [helix] Subject: INFORMATION RELATING TO ME IN THE AUTMATED TARGETING SYSTEM
I am requesting information relating to me in the Automated Targeting System. My request is made pursuant to the Freedom of Information Act, as amended (5 U.S.C. 552). I wish to have a copy of your records made and mailed to me without first inspecting them.
Give me a reason why you would need a removable battery for anything other than having to swap a battery mid-flight from Japan to North America because your laptop battery only gives you a 4-5 hour window of use per charge. If it last for up to 8 hours, that should be more than enough even for a long flight across the Pacific or Atlantic.
Because the 'max' battery life is rarely indicative of how some of us road warriors use a laptop. For example, my Thinkpad x61s with an 8 cell battery will go for about 6 hours trimmed up for full battery optimization. If I play a game, do development work, or push the system hard I get closer to two hours of battery. Pushing excel and minor dev work, something closer to four hours. I find that I spend almost as much time in the airport (where plugins are rare) as I do in the air. Not having a battery pack is just silly.
I've heard rumors that XP 64 can only address something like 8gb of ram is this true?
Windows XP x64 is limited to 128 GB of physical memory and 8 terabytes of virtual memory per process. Good luck finding hardware that will let you test this. I'm running 8G on both my laptop, 8G on my gaming box, and 16G on one of my workstations. The x86-64 workstation has 4x4G as a mainboard limitation, the gaming box (4x2G) and laptop (2x4G) have an 8G limitation. Tis not the OS, however, limiting things to 8/16G.
XP (x64) is a pretty solid OS. I use it on my gaming rig and laptop, is it is nicely compatible with all the old Win32 stuff and has the bonus of sharing much of the Win2003 codebase (and drivers). Vista (and therefor Win7) are suffering from the same 'early years' driver issue that x64 had.
I'm a bit shocked they would bother with a 32-bit OS at this point. By the time it goes GA, can't imagine there will be much left of the 32-bit market.
As does EMC, and a few others... Do shop around, as there are several products out there that can 'tether' assets - not just Microsoft Office documents too.
But this might be enough to do sub orbital. Pop up just high enough to call it space, and head back down again. The plan is not for orbital flight - but our early space program did just what these people are looking to do: an air launched rocket plane that glides back. These folks just need enough thrust to get to the appropriate altitude and return. Escape velocity, and the high mach numbers associated with reentry from that speed don't factor in. Tis probably much lower speeds than the early X-planes were after - were one to actively avoid trying to break the sound barrier on descent.
And from the consumer perspective, there will be deals to be had. Because deals are expected, deals must be put out there. If one of the web based stores does not bother to put out some e-Monday loss leaders, there is a good chance they will get ignored. The web communities I'm involved with do an amazing amount of sifting the wheat from the chaff - retail or online.
Unlike the folks to camped Best Buy for half a day or more, I can log in and snag the loss leaders the web based stores are pushing. Since the press and marketing is hyping the e-Monday, I'll look over the loss leaders they are trying to pitch - and selectivity pick stuff up. Mind you, I've got an idea what a 'normal' deal is already - so if it is not a huge savings, I won't mess with it. They still have to convince people to fill their shopping baskets. Some will. Just saying it is worth a quick scan of what the vendors are putting out there Monday. For both black Friday and eMonday, many sets of eyes are looking for angles.
While I cannot say I spent any quality time with Vista, Window XP-64 is a rock solid gaming OS. With 8G of physical RAM, I've found I can alt-tab in and out of a game with my resource intensive apps running. Using 3.2G of RAM on the 32-bit version of XP, I had to be more cautious.
Granted, 4G RAM chips (since most laptops only have room for two) is a bit outside most (sane) folk's budget. While my laptop has 4G and a 64-bit OS, the video and CPU are not quite there for gaming.

A bit of history on the first one - Head First Java, first edition, was a Java certification guide. The second revision took more of an angle of a general training book, but in the context of a text prep book, it was quite good. Same deal with the EJB and JSP/Servlet book - each mapped to one of the Sun certifications. The Java 'certified' programmer test covered a lot of material without getting into the specialty areas like Enterprise Java Beans or JSP. With Java and C# as close as they are to each other - would not surprise me one bit if they followed the same 'learn this (conditional, flow, io, sockets) as they did for the 2nd+ edition Java book.
