I have found a better solution, the nvidia GTX 280 gets 933 GFlops per a card, so instead of getting 4 8800GTS's you can get 2 GTX 280's for just $200 more ($324 each and the main setup will cost about $1,400) and you still get about 1.8TFlops. It is better to have two cards rather than to have four cards mainly because you have better motherboard communication. And when you are not using this setup as a supercomputer you can use it as a monster gaming rig. An yes i know that this isnt the most perfect setup, and quadro has better compatibility with CUDA, but the PNY NVIDIA Quadro FX 5600 costs around $2,500 ( source : TigerDirect ). And i really dont think the performance vs cost is that much better than Geforce graphics cards. If im wrong feel free to correct me, cause i really would like to know. Thanks.

Sorry it has been so long since i have posted an update, i have been busy with finals and pre-christmas rush at work. During christmas break i should have much more time avaiable to work on the Hak5 air app.

Ok, i did make some changes to my order. I did upgrade to 8 gigs of ram (4 x 2gig) and a 1500watt power supply. Also i did buy some extra fans for my PSC (personal supercomputer) cause on first start up it was starting to run really hot inside. Other than that i did install XP and ClusterKnoppix. I have future plans to cluster more of these together. Right now im working on a basic algorithm that analises two images or frames from a video stream, and caculates disparity from the images and then refines the disparity maps down to a depth map. After i have a stream of depth maps then i can compile it down to a 3d scene witch then it can further refine using more algorithms down to a simpler and small file with no loss. This will make a good project for a grad thesis/project, because i graduate in may and i plan to continue my education. I plan to post images and other data as soon as i can get a camera, ive been trying to wait till i can get my web site up and running before i post anything new. If anyone has any suggestions feel free to suggest. Some links: http://www.engadget.com/2008/05/29/researc...-9800-gx2-card/ http://www.google.com/search?hl=en&rls...ping+algorithms http://clusterknoppix.sw.be/

Right now i am planning to use it for a stock market analytic program that i made with some help form some of the professors at the university i go to. The program uses a complex algorithm to tell me which stocks that i should buy and sell, hopefully it will make me some money one day. You can also use it for password cracking or dictionary attacks. It is crazy fast to do a dictionary attack with this setup. All you need to learn is CUDA which is very easy. You have the option to give it better graphics cards and get this computer up to 8Tflops (not for sure that would work). Also you can cluster many of these together on a network and maybe crack GSM, so then you could intercept transmit, receive free cell phone calls, but that is illegal. With this setup there are basically endless possibilities, maybe even an AI system for the EvilServer, or for your own personal robot.

Ohh, sorry, read it wrong, havent sleep in a while.

Yeah, ill probably invest about a $1000 to $1200 in this computer. Ill take your advice on the PSU and the graphics cards. Also i will need the 4 gigs of memory, Cause the problems that i will be solving with this setup will require lots of memory. Thanks.

OK i finally got the time to build my personal supercomputer. I ordered the parts and the parts are coming. This computers costs about $800, and runs at about 1.2TeraFlops. and for those of you that don't know what a flop is, a flops is Floating point Operations Per Second. As a comparison a Core 2 Duo quad can run at 60GiggaFlops. You could get the same performance out of 20 Core 2 Duo's out of this one graphics card setup. How does a graphics card get so much performance, you might ask. A graphics card has many parallel processing cores, and the graphics processor is mostly based on logic, and not as a controller. I am about to describe the setup for my personal supercomputer, i know there are better options out there, you could go for more power or you could go for less cost, that is up to you. This setup has 4 graphics cards. I have not bought them yet, so if you don't think that this set up will work please let me know. My personal Supercomputer has: # Name/description Cost 1 MSI K9A2 Platinum AM2+/AM2 AMD 790FX ATX AMD Motherboard $103.68 1 AMD Phenom 9600 Agena 2.3GHz 4 x 512KB L2 Cache 2MB L3 Cache 119.99 1 G.SKILL 4GB (2 x 2GB) 240-Pin DDR2 SDRAM DDR2 1066 (PC2 8500) 49.99 4 MSI NX8800GTS-T2D320E-HD-OC GeForce 8800 GTS 320MB 99.99 each 1 SAMSUNG SpinPoint T Series HD320KJ 320GB 7200 RPM 8MB 49.99 1 Sunbeam PSU-HUSH680-US 680W ATX 39.99 1 SIGMA ORCA ORCA-WB Black SECC Steel ATX 29.99 1 LITE-ON Black 20X CD-DVD burner 25.99 Again this setup is not the best. I have been writing a Program in CUDA for a stock analytics, hopefully it will make money some day. I have also considered renting it out, who knows. All off these parts came from newegg and I encourage you to build your own. If you have any comments or changes i should know about feel free to post them. http://www.nvidia.com/object/cuda_home.html Case : Dvd-cd : Graphics card : Hard drive : Memory : Motherboard : Processor : Power Supply :

Yes in the next version i will included many new features. Which will include the ability to change views, hide containers, tab views, Menues, and the missile app, the rest i will leave a surprise. There should also be many bug fixes in the next release, for example, the scrollbar in vista and the incosistent resizing of the app in different modes, should be fixed. I should release beta 9 or the preversion to version 1 on sunday or sometime during next week.

Ive used this in a robot that i built for a friend, it worked out great and was really cool.

In the show Darren just talked about adding range finding to the missile laser setup. And just last summer a friend came up to me and asked for a cheap laser range finding solution for a project that he currently had, so i did some research and found this http://www.pages.drexel.edu/~twd25/webcam_laser_ranger.html . This allows you to get a pretty accurate range with a very cheap setup. Basically you have a laser perfectly parallel to the camera. The software gets the distance of the laser dot from the center of the image, in pixels. And with basic calibration you could have a laser rangfindinger setup in a matter of no time. Also the better the camera is or the more mega pixels the camera can shoot at, a better distance accuracy can be achieved with larger range finding capabilities. If you have a very cheap camera, you might also be able to put a lens in front of the camera, as long as the lens doesn't distort the image and then you could calibrate the software according to the lens, then you could obtain higher range measurements, but you wont be able to view near ranges. So check it out, the link again is: http://www.pages.drexel.edu/~twd25/webcam_laser_ranger.html

Glad you like it. Im currently making beta version 3, which i might call version 1 cause it has many new features and drastic changes, but it is going to take me awhile. Im thinking about releasing a beta 2.2 with some minor changes. One question alot of people have asked for a login, Why would you need a ustream login? Also, i could really use some new or better icons, if you have any just shoot me an email to jcnconnect at gmail.com and i will post them in version 2.2 which should be out very soon. Also if you have any more feature ideas please post them.

That app currently only supports one of the 2 cameras and is not currently in development.

There have been some problems with the width of the app so here is a fix. If this problem still isnt corrected i will try to release another fix ASAP. http://jcnconnect.com/Hak5-Setcam-Streamer-Beta2-1.zip

Ok, i have added some new features to the Hak5 setcam air app. I've added the ability to make the width of the main window larger and the ability to make the width of the streams larger, and also i have added a mini hideable control dock, for those who have limited room. I have also fixed some bugs in the new beta version, but there are still some bugs that i need to work out. The next official release wont be out for at least a week. I will release a fix to any major bugs that occur, just let me know and i will try to do my best to help. And again, if you have any Questions, Comments, Concerns, or feature requests, feel free to let me know. Enjoy. http://jcnconnect.com/Hak5-Setcam-Streamer-Beta2.zip

That is mostly the air framework. Try reinstalling Adobe air. The app is just like a web lanauge, i know the problem shouldnt be in the app. Also try redownloading the app and re-installing it. What directory did you install it in?

Do you have an internet connection, is it installed correctly. Sometimes it takes a while for it to load, Also What os are you using?

I have put together a Hak5 Live Adobe air app so you can view the ustream chat and both ustream video feeds of the Hak House Live from your desktop. This app is in its beta and i did not finish debugging this app. So if you come across any bugs, please let me know and i will post a fix as soon as possible. Also Feel free to criticize my app, but please let me know how i can make it better. If you have any feature requests, comments, or concerns feel free to let me know and i will be glad to help. This Adobe air app will require Adobe air to run. If you do not have it already installed you can download it from one of the links below. Officially adobe air only run on the Windows and Mac Operating systems, But there is a release available for the Linux operating system. It is still only in its beta release but it should work. There will be a link to the Linux Air installer posted at the bottom. The App is the first link at the bottom of this post. http://hakstalkers.com/HSSB2p1.zip http://get.adobe.com/air/ http://labs.adobe.com/technologies/air/linux/ UPDATE:: Make Sure you look below for new updates. There are many comming. UPDATE:: We have switched servers the new link is http://hakstalkers.com/HSSB2p1.zip

Also here is another link for more information : http://en.wikipedia.org/wiki/CUDA

Yesterday i looked at the nvidia tesla supercomputer and i found CUDA. CUDA allows you to do tasks on you graphics card, so basically it turns your graphics card into a GpGpu. It will work on 8400 gs and above cards i think. Programming in CUDA is very simple once you get the hang of it. It is the same as programming in c but with some twists. So i thought it would be cool to get 4 8800 gts graphics cards in my computer running CUDA cracking hashes or figuring out some increadibly complex problem. It can crack hashes possibly hundreds of times faster than your CPU could. This would be a great idea for a future project. Like a Hak5 Personal supercomputer for under $1000. I think there are options for a supercomputer for under $600, because there are 8800 gts graphics cards out there that costs about $100. So i guess everybody could have a supercomputer these days. Any ideas? http://www.nvidia.com/object/cuda_what_is.html

He doesnt really have $40 billion in his pocket, he controls it, through stocks and investments, but still.

With a 2 Petaflop computer or $5mil, you could do really fast genitic calculations, then you could find the cure for many diseases, then you could sell your cheap cure and make a very large return, ohh say $1billion. No top current supercomputer is not doing this, this would be a great idea for bill gates. The current top genitic supercomputer is running at 600Gflops. Bill gates could find a way to invest $100 mil for this.

No too far back Hak5 did an episode on allowing computers, over a network, to work out tasks, together. Kinda like a supercomputer. Today i was on nvidia's website and learned about the Tesla personal supercomputer, it runs about 4Tflops at under $10,000, and i thought wouldn't it be cool if someone had 10 - 100 of these on a network, working together, imagine what you could do with this. For under $2.5 million (not including other costs) you could be number one on the Top 500 supercomputer list. That would be really cool. http://www.top500.org/list/2008/11/100 http://www.nvidia.com/object/personal_supercomputing.html

Well overclocking it wont be easy, or may be impossible, all standard models are equipped with an overclocking lock. It should bring down the cost of the intel quad core extreme, which is what im hoping for. I hate that you cant upgrade your current core 2 for a i7. It requires a whole new platform to run, which i expect to be really expensive.

I cant wait, i was hoping there would be more than 4-8 cores but iguess this will have to do. Im still wanting to know when they are going to release the 80 core processor, at 1 tera-flop http://news.cnet.com/Intel-shows-off-80-co..._3-6158181.html http://www.pcworld.com/businesscenter/arti...lem_nov_17.html
