  • Embedded computer vision platforms

    - by Egon
    Hi folks, I am planning to start a computer vision based project on a smart phone platform. I know iPhone ( http://niw.at/articles/2009/03/14/using-opencv-on-iphone/en ) and Andriod ( http://github.com/billmccord/OpenCV-Android ) have openCV support. I am interested in knowing how was your experience with the level of integration, support and ease of building good apps on either platform. Also I do want to consider windows phone 7 ( and Zune) as a platform, Are there any Computer Vision libraries for that platform or any good development tools( does Aforgenet work or any other good suggestion) ? Also can you suggest some popular augmented reality apps which uses cutting edge technology ( I am aware of http://www.pranavmistry.com/projects/sixthsense/ ) Thnx in advance!

  • How to run a program on a specific remote computer

    - by lucc
    Hi, I have got this working line of code I would like to run via VBScript a share program on a remote computer in a domain environment. The first part is ok where it is asking me to enter a computer name, but the problem is in the second part. I don't know how to run the program on the remote computer that I've entered in the first part. computer = inputbox ("What computer do you wish to check? (Press Enter if this computer)","Computer") set WMI = GetObject("WinMgmts://" & computer) If computer="" then computer = "this computer" Dim objShell Set objShell = WScript.CreateObject( "WScript.Shell" ) objShell.Run("""\\compname\Share\progr.exe""") Set objShell = nothing After running this script, it runs the program on my computer, not on the remote computer. I want to run the program on a specific computer that I have entered from keyboard. Please help. Thank you.

  • SAS(Statistical Analysis System) Career As a computer science student

    - by Renju
    Hi. I have completed MSc in Computer science this academic year. So I am fresher... While I am doing graduation and post graduation I did many projects using PHP and MySQL. Now I got opportunity to get into SAS(Statistical Analysis System) career, and I heard that SAS having better career growth than PHP developement. For the past 4 days, I was working with SAS and I feel interested in working. My questions are, Since i am a computer science student whether i will have any problem in my career growth in SAS? I am ready to learn statistics also, is there anything else I have to do? Doing certification in SAS will make any changes? Is it a bad idea to get into SAS with only CSc backgrond? So please guide me for my career...

  • Keeping Computer Science Writing Accessible and Eloquent

    - by Federer
    This question is particularly aimed at descriptions and explanations of what is happening in a computer program, as well as any general advice or approaches for undertaking technical reports in Computer Science at both undergraduate and graduate levels. You see, I am having particular difficulty in the best way to explain what is happening. As in, given any given program from a multi-agent system to a standard webservice, the best and most eloquent way to say exactly what is going on, the logic behind it and it's respective justifications. Should I avoid saying class names? Avoid specifying methods? Keep referring to class variables and any particular references? I'm banging my head against the wall at trying to keep a solid technical foundation and making it accessible to people of all backgrounds. Apologies for the rather vague question. Cheers.

  • Networking conflict - What is the most common default computer name?

    - by John
    I recently had to change the name of my computer to log onto a public wi-fi spot, because a computer with my name was already logged on. (I asked a guy there what to do after it said there was already a computer named "Dell(omitted)" logged on.) I've never been at a wifi spot that you had to log into before. I didn't even notice what the computer's name was before. My question is what are the most common default computer names. I'm curious. How often does this sort of problem happen? (I read via Google that Redhat linux default to "localhost" and Toshiba laptops default to "Toshiba.") Somebody probably keeps statistics. (I was referred here from serverfault.com) Thanks

  • tmpreaper, --protect and a non-root user

    - by nsg
    Hi, I'm a little confused. I have a download directory that I want to remove all files older then 30 days with tmpreaper. Just one problem, the directory in question is a separate partition with a lost+found directory, of course I need to keep it so I added --protect 'lost+found', the problem is that tmpreaper outputs: error: chdir() to directory 'lost+found' (inode 11) failed: Permission denied (PID 30604) Back from recursing down `lost+found'. Entry matching `--protect' pattern skipped. `lost+found' I have tried with other pattern like lost* and so on... I'm running tmpreaper as a non-root user because there is no reason for superuser privileges because I own all files (except lost+found). Are I'm forced to run tmpreaper as root? Or are my shell-skills not as good as I thought? I guess the problem is: tmpreaper will chdir(2) into each of the directories you've specified for cleanup, and check for files matching the <shell_pattern> there. It then builds a list of them, and uses that to protect them from removal. Any thought and/or advice? Edit: The command I'm trying to run is something like $ /usr/sbin/tmpreaper -t --protect 'lost+found' 30d /mydir 1> /dev/null error: chdir() to directory `lost+found' (inode 11) failed: Permission denied Edit 2: I read the source code for tmpreaper-1.6.13 and found this if (safe_chdir (dirname)) exit(1); and if (chdir (dirname)) { message (LOG_ERROR, "chdir() to directory `%s' (inode %lu) failed: %s\n", dirname, (u_long) sb1.st_ino, strerror (errno)); return 1; } So it seems tmpreaper needs to be able to chdir in to all directories, ignored or not. I see two options left Run tmpreaper as root Move the download directory Find a alternative tool (tmpwatch?) I will give it some more research before i make a choice.

  • How to protect Ubuntu from fork bomb

    - by dblang
    I heard someone talking about a fork bomb, I did some research and found some dreadful information about some strange looking characters people can have you type at the command line and as a result do bad things on the computer. I certainly would not issue commands I do not understand but one never knows what can happen. I heard that some OS allows the administrator to place some limit on user processes to mitigate the effects of fork bombs, is this protection in Ubuntu by default or would a person with sudo privilege have to set this? If so, how?

  • How do people prove the correctness of Computer Vision methods?

    - by solvingPuzzles
    I'd like to pose a few abstract questions about computer vision research. I haven't quite been able to answer these questions by searching the web and reading papers. How does someone know whether a computer vision algorithm is correct? How do we define "correct" in the context of computer vision? Do formal proofs play a role in understanding the correctness of computer vision algorithms? A bit of background: I'm about to start my PhD in Computer Science. I enjoy designing fast parallel algorithms and proving the correctness of these algorithms. I've also used OpenCV from some class projects, though I don't have much formal training in computer vision. I've been approached by a potential thesis advisor who works on designing faster and more scalable algorithms for computer vision (e.g. fast image segmentation). I'm trying to understand the common practices in solving computer vision problems.

  • [MINI HOW-TO] Remove a Network Computer from Windows Home Server

    - by Mysticgeek
    One of the cool features of Windows Home Server is the ability to backup and monitor the computers on your network. If you no longer need a machine on to be monitored or backed up, here we show you how to remove it. Remove Computer from WHS The process if straight-forward and basic –Open Windows Home Server Console and click on Computers & Backup. Right-click on the computer that you no longer need and click Remove. You’ll be prompted to verify that you want to remove the machine and delete all of its backup data. Check the box I am sure I want to remove this computer then click the Remove button. That’s all there is to it! The computer and all of its backup data is removed. Remember that if you remove a computer, all of its backup data will be deleted as well. If you no longer have the computer, you probably don’t need the backed up data anyway, but you’ll want to be sure you no longer need it before removing it.

  • Copy Ubuntu distro with all settings from one computer to a different one

    - by theFisher86
    I'd like to copy my exact setup from my computer at work to my computer at home. I'm trying to figure out how to go about doing that. So far I've figured this much out. On the source computer run dpkg --get-selections > installed-software and backup the installed-software file Backup /etc/apt/sources.list Backup /usr/share/applications/ to save all my custom Quicklists Backup /etc/fstab to save all my network mounts Backup /usr/share/themes/ to save the customization I've done to my themes I'm also going to backup my entire HOME directory. Once I get to the destination computer I'm going to first do just a fresh install of 11.10 Then I'll copy over my HOME directory, /etc/apt/sources.list, /usr/share/appications, /etc/fstab and /usr/share/themes/ Then I'm going to run dpkg --set-selections < installed-software Followed by dselect That should install all of my apps for me. I'm wondering if there's a way/need to backup dconf and gconf settings from the source computer? I guess that's my ultimate question. I'd also like any notes on anything else that might need backed up as well before I undertake this project. I hope this post is legit, I figured other people would be interested in knowing this process and I don't see any other questions that seem to really document this on here. I'd also like to further this project and have each computer routinely backup all the necessary files so that both computer are basically identical at all times. That's stage 2 though...

  • What is the biggest weakness of students graduating with degrees in Computer Science?

    - by akobre01
    This question is directed more toward employers and graduate student advisors/professors but all opinions are welcome. What do you find is a common weakness of new hires and/or new grad students? Is it entirely variable dependent on the student and his or her university? Is there a particular skill or skillset that you wish new hires/researchers had expertise in and how can we remedey this deficiency? I realize that this question is general and really encapsulates two questions, one more about the weaknesses of new software engineers and one about the weaknesses of new researchers. However, both types of people tend to come from similar courses of study so I'm wondering if there is any overlap. Note: I am not a professor but I'm interested in how best to revise the undergraduate curriculum in CS.

  • Computer Generated Vocals

    - by anon
    Is this even possible? I.e. suppose you were given: 1) Lyrics to a song. 2) Background music of a song. 3) Timing of what syllables should be uttered when. 4) What note what each syllable should hit. Given the above, is it possible to automatically generated the vocals via a computer program? Thanks!

  • JavaScript computer algebra system

    - by Jonas
    I am looking for a simple computer algebra system (cas) for JavaScript but I can't find anything with google. I only need basic functionality: simplify expressions to some canonic form. Ability to check if two expressions are the same, i.e., a(x+y) == ax+ay parse mathematical formulas. I want it to be able to read expressions like ax²+4x. solve simple equations etc. Do you know of such a library?

  • Computer Science + CFA

    - by scatman
    I still have one semester to finish my MS in Computer Science, and I am already working for a software development company. I took some accounting courses as electives (accounting 1-2 and finance) and I found them interesting and easy. Is it worth it to do CFA? I don't want to change majors, i.e. I still want to be a developer, but would it help if I did CFA?
