Its not even a refridgeration cycle!!!!!!!!

Sandia's Smart Heat Pipe

· Score: 3, Insightful
In a fridge you have coolant moving through pipes at high pressure, the pressure is dropped which then causes it to suck heat out of something( ie your food), the heat is then dissipated thorugh a heat exchanger and then a compressor recompresses the fluid. A refridgeration cycle does not work without a compressor or it would defy the laws of thermodynamics.
This is however closer to a more advanced heat fin technology, heat fins are used to wick heat away from a heat source, but eventually a point in the fin becomes too cold to tranfer heat and making the fin longer doesnt' do you any good, so what do you do now?
Use a heat pipe to move the heat form one place to another, namely another set of fins, or the same fins to get more use out of their length.
So what is the main difference between your fridge and a heat pipe, one sucks energy out of something , making it colder then room temperature, and another one transports heat to another source but can never make it cooler then room termperature.
It is an interesting product. The problem with it is if the process uses shared memory it won't shove the process over to the other node, as it can't share memory from one node to the other.
It works great for compiling code, converting a bunch of files at once from one format to the other. But the problem is it can't share the memory from one system to the other so it won't send database processes from one node to the other. I believe it said it wouldn't work for a web server either, but you would probably just have to test your application.
Its pretty easy to set up, the config file is similar to/etc/hosts, just needs an extra network adapter per card, definitly shouldn't take to long to try it out anyway.
The problem is technically speaking they are Red Book compliant, because the subchannel data that they modify isn't in the red book. Techinially they should play on any vanilla cd player, the problem is with cd players playing mp3s and that kind of stuff they are no longer just cd players. They tend to mark tracks as data as opposed to audio, screw up the cd start time to an invalid number, and sometimes create multisessions that end past the point of the cd. The last methods is the one the marker takes care of. The subchannel timing isssues can be solved with better error handling in the firmware, these methods rely on the firmware's inability to handle the errors. The end result however is it just pisses people off because you can make a perfect digital to digital copy with a cd player and spdif out and in ports. Which then can be turned into mp3s or sold on the streets by other pirates. Not to mention eventually more and more cd-players will have more robust firmware and in the end it won't even be an issue. These companies pay millions of dollars to come up with ideas that aren't all that difficult to solve. Might be a good thing for phillips since they may corner the market for cd-burners that burn anything and play any crippled cd.
id software has a large following so I seriously doubt it will only sell 20,000 games. The doom and quake series alone have been phenomenal sellers.
That being said I believe their take on it, especially the first game with the new engine is make the best engine possible, create a really cool game around it, and sell the first game to the early adopters(hard core gamers). Soon afterwards the hardware will catch up, and then we can sell the engine to a handfull of other companies to make really cool 3d games, make an even cooler game with the current engine while Carmack starts making the new engine.
take 10,000J/.1 seconds and you would also have 100KWatts as well, which do you think will do more damage and bust through the mirrors??
his 500mJ, 500ns so called 1Megawatt laser or the 10KJ 100 millisecond one?
Would be finding one that woulnd't be instantly vaporized when touched by a laser of that magnitude.
Certainly paint isn't going to work as it would instantly oxidize and loose all reflective properties. Polished metals might help but they too would loose structural integrity. The mirror would have to be close to if not 100 percent reflecive of all the radiation being pointed at it and remain so for the duration of the attack.
As far as using smoke cloud around missles as protection, they too need to see for guidance purposes, plus it would be almost impossibly to keep a leading smoke edge on something moving that quickly as the drag on the particles would loose the impulse of the rocket engine as soon as they were ejected, leaving the rocket exposed.
Not much different then the Microsoft EULA

First Worm with a EULA?
·
· Score: 2, Interesting
Granted the microsoft one isn't dling the contacts, but you agree to having microsoft search your machine for installed software(automatic update) and then download and in some cases automatically install any code that it deems is a critical update.
I would imagine that the makers of this worm felt that if microsoft can get away with it then they could too. The fact remains is that Microsoft should have no right to demand access to data on my machine nor the right to install code on my machine. The worm just shows an example of just how rediculous Microsofts use of the EULA is.
First of all, it was probably at 4-10 K because it is unstable at room temperature meaning( ie 0Hz at room temperature).
Second of all thank god air molecules aren't actually traveling around the room at 300m/s. I mean a tornado can send a pencil thorugh a telephone pole at a slower velocity. Thanks for showing why you can't indiscriminately put two energy equations together and come out with the right answer.
Its kind of weird but as long as the intent of the mod chip was to make sure people could run copies of the games they purchased mod chips are perfectly legal, even under the DMCA, which follows fair use.
The problem is probably more similar to DeCSS as not only does Microsoft's BIOS make sure you are not running an original CD, it makes sure that you aren't running software written by someone who hasn't paid Microsoft the proper royalties.
The question would then become is installing linux on the XBox really i violation of their royalty policy, can they stop someone from making it do something it was never intended to do. I'm not so sure. They could easily sue someone who is making an Xbox game without their approval. And if they don't have a right to stop someone from writing code to distribute linux on their hardware, then they can't stop the production of a hardware chip that allows it. But that's only true if the other side has enough money to fight microsoft in court.
Hehe, yeah they did this in our lecture too, though the lecture hall had a 30 foot ceiling( which was needed) They had the aluminum oxide adn iron oxide in two clay plant pots, the smallish kind. This created a 20 foot shower of sparks and then a decent chunk of molten iron poured out of the bottom hole of the clay pot.
Personally much more impressive then sodium water and water.
In my chemistry class in college instead of sodium and water they put sodium into a big jar of chlorine. The flame was so bright i saw spots for a long time.

Yeah especially since they apparently didn't have a decent backup of the critical data, no wonder they eventually got canned.
I can't remember the link to the article, but Janus Ian states in an article that she wrote that what you do isn't exactly hurting the record industry either as the artists are forced to buy the CDs they sell at concerts at aproximately 12 dollars a peice. In short the only way to hurt the RIAA is to only by CDs produced by independent labels. She even states at one point that she has never had a royalty statement that didn't show she owed her label money.
The fonts are generally licensed per user, per a certain number of printers. I think the common license is 5 users two printers. Well your service bureau/printer doesn't have access to the license. The reason why its technically OK for you to do this is because they have already purchased the fonts as well.
As far as the adobe acrobat format is concerned, i agree with you, the fact that you make the pdf is as if you printed it. It whould be considerd an electronic piece of paper. You can photocopy something printed with their fonts without a license, this is just the electronic form of photocopying.
Their issue with it however is now you can send that to someone else who can print it, and make an exact perfect replica. Now the whole printer license is messed up. And since you embedded the font in the pdf, they can but legally do not have the right to print it. Adobe allows this by ignoring the Allow_embedded bit, and is therefore violating the DMCA.
This is defniitly a greed case, generally these fonts are licnesed per user with a limit on how many printers that user can use. So technically you could purchase one of these fonts, make a document print it millions of times and distribute the copies. There isn't anything that different in this case, other then the companies don't view the pdf as a peice of paper, but as a document that can be printed again. These are the same people taht charge you like 20 bucks for the italics version of the font you like, a whole font family could cost easily 300 bucks.
In a normal scenario if you don't print the documents in house, then the designer's printer must buy the fonts as well. So this is another 300 bucks for the font makers. This is what they could be missing slightly as people could technically make a pdf and have that printed at a printer and the fonts wouldn't be needed. But this just isn't reality.
The font publishers would do better for suing adobe to make them take out the option of bundling the fonts with the package for the printer, as in this is a violation of the copywrite. Its a common practice of the designer to bundle the fonts regardless, but it is illegal, and Adobe easily allows the designer to bundle the fonts with the package to be sent off to print.
Certain backup software uses disk pools as a primary or initial backup method. The reason for this is that you get better tape performance if you can send a bunch of it at once. Plus if you have enough disk space for a complete incremental backup of all your systems the restores the next day will be quicker, then off load to tape. And certain packages Tivoli Storage Manager for instance has an incremental forever policy, depending on your needs you may not need to make a full archival copy every again, it would just stay on the system for a year. If you wanted to you could, but you don't have to. This saves on backup time and tape space as you only backup the file when it changes, and no its not like you need a years worth of tapes to restore either, there is a database that knows where the file you want is.
Tivoli Storage Manager has an incremental forever strategy. Sure the first backup would take a long time but every other backup would be quicker. Also the use of compression can increase the throughput 2-8 times depending on the type of data.
On almost every model 20 percent of the users use 80 percent of whats available. The last place I worked the top 20 percent users used almost 80 percent of the exchange database, another 20 percent used 80 percent of the network storage... My grandfather sold 80 percent of his product to the top 20 percent of his clients. It is pretty much a universal law, strange but true. So when they say 1 percent is using 16 percent, thats probably just about right.
Remember statistics don't lie, only statisticians do.
I definitly noticed pixilation on all the Type, especially the smaller type. in some cases with characters up against dark backgrounds and about half way back in the room they were in you could start ot see some pixilation on the edges of their faces. I was specifically looking for it though, many people may not of even noticed it. My first thought after seeing the movie besides wow that was the best theater experience of my life was I wish it was higher resolution.
They get away with 1280x1024 because each pixel is the exact color it is suppose to be, its not a grouping of three dots so the effective resolution is higher. HDTV 1080i is lower res but it looks alot better then the move did on a 40 foot wide screen. The pixel density on a HDTV screen is alot tighter. The smaller the screen the better its going to look.
