  • Port scientific software to GPU and publish it

    - by Werner
    Hi, let's say that I am a physicist and that I am the master of the universe when it comes to port salready existing oftware to GPU's with 100x or more speedups. Let's say that I find that some other scientist, which does not know how to program GPU, publishes the Open Source code in his/her website of a physical simulation program, in the field I am expert on. Let's say that I realize "I can port that code to GPU", and I suggest him, but he shows no interest. My interest here is, 1) to port it to GPU, 2) to publish this result in a scientific journal related with physics and/or computer science My question for you is 1- would you proceed here to port the code to GPU (or other new arch) and publish it? 2- how would you do it and which journal do you suggest? Thanks

  • Is 1GB RAM with integrated graphics sufficient for Unity 3D on 12.04?

    - by Anwar Shah
    I have been using Ubuntu since Hardy Heron (8.04). I used Natty, Oneiric with Unity. But When I recently (more than 1 month now) upgraded My Ubuntu to Precise (12.04), the performance of my laptop is not satisfactory. It is too unresponsive compared to older releases. For example, the Unity in 12.04 is very unresponsive. Sometimes, it requires 2 seconds to show up the dash (which was not the case with Natty, though people always saying that Natty's version of Unity is buggiest). I am assuming that, May be my 1GB RAM now becomes too low to run Unity of Precise. But I also think, Since Unity is improved in Precise, It may not be the case. So, I am not sure. Do you have any ideas? Will upgrading RAM fix it? How much I need if upgrade is required? Laptop model: "Lenovo 3000 Y410" Graphic : "Intel GMA X3100" on Intel 965GM Chipset. RAM/Memory : "1 GB DDR2" (1 slot empty). Swap space : 1.1GB Resolution: 1280x800 widescreen Shared RAM for Graphics: 256 MB as below output suggests $ dmesg | grep AGP [ 0.825548] agpgart-intel 0000:00:00.0: AGP aperture is 256M @ 0xd0000000

  • OpenCV - DLL missing, but it's not?

    - by charles-22
    I am trying just a basic program with OpenCV with the following code: #include "cv.h" #include "highgui.h" int main() { IplImage* newImg; newImg = cvLoadImage("~/apple.bmp", 1); cvNamedWindow("Window", 1); cvShowImage("Window", newImg); cvWaitKey(0); cvDestroyWindow("Window"); cvReleaseImage(&newImg); return 0; } When I run this, I get The program can't start because libcxcore200.dll is missing from your computer. Try reinstalling the program to fix this problem. However, I can see this DLL. It exists. I have added the following to the input dependencies for my linker C:\OpenCV2.0\lib\libcv200.dll.a C:\OpenCV2.0\lib\libcvaux200.dll.a C:\OpenCV2.0\lib\libcxcore200.dll.a C:\OpenCV2.0\lib\libhighgui200.dll.a What gives? I'm using visual studio 2008.

  • What are the CS fundamentals behind package/dependency management?

    - by Frep D-Oronge
    Often I hear about situations where companies are developing extensable in house software (the dreaded enterprise 'framework') which is supposed to support multiple 'plugins' from diffirent teams. Usually this ends up being a half baked solution that does not really work due to compatibility prolems between addins, or between addins and the framework itself. Usually this means QA have to 'rubber stamp' a global set of versions accross all plugins, or more usually plugins are released and stuff breaks in nasty ways. This problem has been solved before however, for example the package management systems like apt for debian linux. I suspect that the reason it works is that it is built from the start on a known 'Computer Science-y' concept. My question is what is it?

  • Static Evaluation Function for Checkers

    - by Kamikaze
    Hi all! I'm trying to write an evaluation function for a game of checkers that I'm developing but I can't find the right documentation. I've read several documents on the web witch describe different techniques for either writing one or letting the computer find it(using genetic algorithms or Bayesian learning) but they're too complicated for a novice like me. All documents pointed a reference to "Some studies in machine learning using the game of checkers" by A.L.Samuel but I couldn't get my hands on it yet :(. I've only read the follow up "Some studies in machine learning using the game of checkers -II" and found some good info there, but it doesn't explain what the eval parameters mean (I think I don't have the whole article). Thanks for your help!

  • xorg, nvidia, log-in all hosed - how can I completely reset graphics set-up/settings?

    - by Fred Hamilton
    I just did a fresh install of Mythbuntu 12.04.1 on my Intel MB with nVidia 9500GT graphics card. Hardware's been working great with 10.10 for about 2 years. Background: (optional - feel free to skip to question) I was trying to get my component video output to generate 720p, messing around with the nvidia drivers, and now the entire display system is hosed. I can SSH in and get a terminal. Depending on which nvidia package I install/remove, I get: Garbage on screen (after I "apt-get remove nvidia*") A low-res graphical log-in screen where I can log in as fred or guest. If I log in as fred, it displays some text mode status line then goes right back to the log-in screen. If I log in as guest, I actually get the full Ubuntu desktop, but I need to be able to log in as fred. Other times I get an error: "API mismatch: the NVIDIA kernel module has version 304.43, but this NVIDIA driver component has version 295.49." I've googled around, including trying this thread with the same error message, but to no effect. Question: How can I just reset x settings, drivers, everything display-related to the exact same way it was after a fresh install?

    - by digitalcrow
    I have problem with nvidia graphics driver opensource and proprietary ! Can't change resolution on 3d games and there's a bug there are no kernel sources installed and thus jockey can't install proprietary drivers. I can't change resolution while on games fullscreen. I tried to install proprietary driver and i couldn't plus i couldn't login to ubuntu it showed only the desktop photo no dash no nothing. -tried to install kernel sources and blacklist+remove Nouveau drivers and then installed the proprietary drivers i hope succesfully. -The problem is the same i can't change resolution on 3d games while on fullscreen. I've installed the sources and be able to install the proprietary nvidia drivers but the problem remains, look what i got in the output of a 3d game exited while i tried to change resolution: X Error of failed request: BadValue (integer parameter out of range for operation) Major opcode of failed request: 150 (XFree86-VidModeExtension) Minor opcode of failed request: 10 (XF86VidModeSwitchToMode) Value in failed request: 0x25b Serial number of failed request: 497 Current serial number in output stream: 499 I'm giving you more details about my system: i have an nvidia geforce gts 250 , 3,4 ghz quadcore amd phenom2 , 8gbytes of ram.

  • Framework/tool for processing C++ unit tests with numerical output

    - by David Claridge
    Hi, I am working on a C++ application that uses computer vision techniques to identify various types of objects in a sequence of images. The (1000+) images have been hand-classified, so we have an XML file for each image containing a description of where the objects are actually located in the images. I would like to know if there is a testing framework that can understand/graph results from tests that are numeric, in this case some measure of the error in the program's classification of the images, rather than just pass/fail style unit tests. We would like to use something like CDash/CTest for running these automated tests, and viewing over time how improvements to the vision algorithms are causing the images to be more correctly classified. Does anyone know of a tool/framework that can do this?

  • Write the longest possible loop.

    - by Abhay
    Hello Group, Recently I was asked this question in a technical discussion. What is the longest possible loop that can be written in a programming language? This loop has to be as long as possible and yet not an infinite loop and should not end-up crashing the program (Recursion etc...) I honestly did not know how to attack this problem, so I asked him if is it practically possible. He said using some computer science concepts, you can arrive at a hypothetical number which may not be practical but nevertheless it will still not be infinite. Anyone here; knows how to analyse / attack this problem. P.S. Choosing some highest limit for a type that can store the highest numerical value is apparently not an answer. Thanks in advance,

  • What is this Hash-like/Tree-like Construct Called?

    - by viatropos
    I want to create a "Config" class that acts somewhere between a hash and a tree. It's just for storing global values, which can have a context. Here's how I use it: Config.get("root.parent.child_b") #=> "value" Here's what the class might look like: class Construct def get(path) # split path by "." # search tree for nodes end def set(key, value) # split path by "." # create tree node if necessary # set tree value end def tree { :root => { :parent => { :child_a => "value", :child_b => "another value" }, :another_parent => { :something => { :nesting => "goes on and on" } } } } end end Is there a name for this kind of thing, somewhere between Hash and Tree (not a Computer Science major)? Basically a hash-like interface to a tree.

  • How do I solve "System is running in low graphics issue" in Ubuntu INSTALLER ?

    - by hellodear
    I made a bootable USB for installing Ubuntu 12.04 LTS alongside Windows 8.1. I inserted my USB device and then booted into it. Then it showed me 2 options - 'Try Ubuntu' or 'Install Ubuntu'. Now I press 'Try Ubuntu' and then it says, "The system is running in low graphics mode". Then I press 'OK'. Then it showed me 4 options. Then again I click 'OK'. Then it shows a black screen and nothing happens. I have tried all possible answers provided in AU. What should I do? Please help. PS :- I am using Windows 8.1 with dedicated graphic card which is AMD Radeon HD 8670M. I am trying to do this in a Dell Laptop 3537 Inspiron. UPDATE :- I tried running the liveUSB session with nomodeset on and i was able to enter the installer. But when I run boot-repair(so that my Ubuntu gets detected in the GRUB menu) after installing Ubuntu successfully alongside Windows 8(following this tutorial with nomodeset on, I get the following error:- your system is running in legacy mode boot repair done

  • Detecting video playing in browser from a screenshot -- OpenCV

    - by Jon
    I would like to draw a rectangle around a video playing on my screen. For example, I am watching a YouTube video in my browser. I would like to be able to take a screenshot, analyze that screenshot, and then draw a rectangle around where the YouTube video is playing. I have just started looking into how I might be able to to this. I came across OpenCV. I understand that OpenCV covers many computer vision techniques. Would any of them be particularly well suited for this task? Also, is this something that can be done in real time? Finally, is there a technique that would work for both in browser and full screen? Thanks!

  • CS Education, where was it? Where is it now? Where is it going?

    - by CheesePls
    I'm planning on doing research into Computer Science education for my senior project and I could think of no better group of people to consult than the SO community. So, what do you think about the state of CS education in the United States (and the rest of the world, though I had planned on focusing on the US)? What do you feel are necessary topics? What topics are superfluous? Objects first vs. Objects early vs. Objects later? ALSO, if anyone has or knows of any blogs, studies, etc., those would be very helpful as well.

  • Why is Mac supposedly better than Windows for graphics?

    - by Svish
    Ok, people just keep telling me that if you're going to be working with graphics and design and stuff, you should get a Mac. And I just don't get the logic. Because most of these people would be working with Adobe software, which are for both Windows and Mac. To me it seems like their whole argument is based on that "everyone else does". Like, Mac had some graphics software that Windows didn't earlier in history, so most people were using Mac. And since most people were using Mac, new people also started using Mac. And since most people were using Mac, schools and universities used Mac. Which taught new people to use Mac. So they were using Mac. And told everyone they met that everyone they knew were using Mac. And so on. Anyways... What is the deal really? Is there actually any advantage in using Mac for graphics and design and such things? My take is that you pretty much have the same software and both Mac and Windows are powerful enough, support enough RAM, are stable (as long as you don't install lot's of junk or faulty drivers), et cetera. So, can anyone give me a good explanation on this? Is there a real difference or are people just brainwashed?

  • How can something relevant to graphics completely kill a motherboard?

    - by leladax
    I was coding something in OpenGL and after a bug there was an 'OS slowed down' situation. After a few seconds the screen went blank and the laptop shutdown. Now not even a led turns on battery or not. It doesn't appear to be the AC or the battery since there was some battery when it died and when it's connected to the AC the laptop produces near the AC connection a very slight 'clicking' noise (very faint, one has to be very careful to notice it, I don't know if it was there forever tbh). I suspect the motherboard died, as in something from the point it gets AC or battery power and the point it actually feeds itself. But I can't figure out how that effect was produced by the OpenGL bug or graphics overheating. If the graphics died alone, it should at least give some indication that the laptop is barely alive, at least a led, a sound, anything, the laptop is instead completely dead (other than faint 'clicking' I mentioned). Does anyone have expert advice on this? I'm especially interested in any ideas connected to "graphics overheated/bugged ---- they killed motherboard". I have a very lengthy experience in that stuff as a hobbyist and it really puzzles me. It's not just a "AC died" situation I can easily google.

  • Specialized course in Web programming or Generalized course in Computer Science?

    - by Sugan
    I am planning to do my masters in Computer Science in UK. I am interested in Web programming. What should I opt for. A general course in Computer Science or in some specialized course in Web Programming. If web programming, are there a lot of colleges offering these courses. Are there a lot of job offers there in UK. I am not sure whether I can ask this question here. If not point me where I can ask this question.

  • Step Away From That Computer! You’re Not Qualified to Use It!

    - by Michael Sorens
    Most things tend to come with warnings and careful instructions these days, but sadly not one of the most ubiquitous appliances of all, your computer. If a chainsaw is missing its instructions, you’re well advised not to use it, even though you probably know roughly how it’s supposed to work. I confess, there are days when I feel the same way about computers. Long ago, during the renaissance of the computer age, it was possible to know everything about computers. But today, it is challenging to be fully knowledgeable even in one small area, and most people aren’t as savvy as they like to think. And, if I may borrow from Edwin Abbott Abbott’s classic Flatland, that includes me. And you. Need an example of what I mean? Take a look at almost any recent month’s batch of Windows updates. Just two quick questions for you: Do you need all of those updates? Is it safe to install all of those updates? I do software design and development for a living on Windows and the .NET platform, but I will be quite candid: I often have little clue what the heck some of those updates are going to do or why they are needed. So, if you do not know why they are needed or what they do, how do you know if they are safe? Of course, one can sidestep both questions by accepting Microsoft’s recommended Windows Update setting of “install updates automatically”. That leads you to infer that you need all of them (which is not always the case) and, more significantly, that they are safe. Quite safe. Ah, lest reality intrude upon such a pretty picture! Sadly, there is no such thing as risk-free software installation, and payloads from Windows Update are no exception. Earlier this year, a Windows Secrets Patch Watch article touted this headline: Keep this troublesome kernel update on hold. It discusses KB 2862330, a security update originally published more than 4 months earlier, and yet the article still recommends not installing it! Most people simply do not have the time, resources, or interest, to go about figuring out which updates to install or postpone or skip for safety reasons. Windows Secrets Patch Watch is the best service I have encountered for getting advice, but it is still no panacea and using the service effectively requires a degree of computer literacy that I still think is beyond a good number of people. Which brings us full circle: Step Away From That Computer! You’re Not Qualified to Use It!

    I just installed Ubuntu 12.04 on a computer. I want to use this computer as a router for my other computers. The computer only has 1 network card, there is no slot for a second card. I can get the computer to connect to my ISP via pppoe and it can access the web. However the other computers on my local net can only see the router computer. I have tried 2 different pppoe packages, roaring penguin and network-manager-gnome. When I get it to work I will be replacing a 15 year old computer that is running Slackware 7.1. The old computer is currently my router. It is running Roaring Penguin I tried to setup the new computer with the same Roaring Penguin parameters as the old computer. Bob

  • Accessibility and usability issues when designing websites for older computer users

    - by Vafello
    As a part of my final year university project I am designing a social networking website targeted mainly to older users. I was wondering what accessibility and usability issues should be taken into account when creating a website for such users, apart from obvious ones - such as bigger font, compatibility with current standards, straight-forward interface. Or maybe an older user is just the same as an average user and no special design is needed? Let me know what you think. Thanks.

  • Robotium - Write to file in eclipse workspace or computer file system

    - by Flavio Capaccio
    I'm running some tests using Robotium on an Android application that interacts with a web-portal. I'd like to save some information to file; for example I need to save the id of the username I created from the app and I want to make it read from Selenium to run tests on web-portal to verify a webpage for that user has been created. Is it possible? Could someone suggest me a solution or a work-around? This is an example of code, but it doesn't work (I want to write to a file for example on c:\myworkspace\filename.txt a string): public void test_write_file(){ if(!solo.searchText("HOME")){ signIn("39777555333", VALID_PASSWORD); } try { String content = "This is the content to write into file"; File file = new File("filename.txt"); // if file doesnt exists, then create it if (!file.exists()) { file.createNewFile(); } FileWriter fw = new FileWriter(file.getAbsoluteFile()); BufferedWriter bw = new BufferedWriter(fw); bw.write(content); bw.close(); } catch (IOException e) { // TODO Auto-generated catch block e.printStackTrace(); } assertTrue(solo.searchText("HOME")); }

  • MissingMethodException when running application on different computer
