  • After upgrading to 12.10 usb drives fail to mount

    - by John Shore
    Following upgrade to 12.10, my usb drives - both pen drives and a usb hard drive - fail to mount with the error message: Unable to mount *name of drive* volume Adding read ACL for uid 1000 to '/media/*my home file name*' failed: Operation not supported This is on a desktop Dell Inspiron 530. I also have a Dell Inspiron Mini 10 netbook which I also upgraded to 12.10 (slightly smaller installation on a flash hard drive). all devices mount automatically without problems on this computer.

  • Interesting Topics in Comp. Sci. for New Students?

    - by SoulBeaver
    I hope this is the right forum to ask this question. Last friday I was in a discussion with my professors about the students' lack of motivation and interest in the field of Computer Science. All of the students are enrolled, but through questionnaires and other questions that my professor posed it was revealed that over 90% of all enrolled students are just in it for the reward of getting a job sometime in the future (since it's a growing field with high job potential) I asked my professor for the permission to take over the first couple of lectures and try and motivate, interest and inspire students for the field of Computer Science and programming in particular (this is the Intro to Programming course). This request was granted and I now have a week to come up with a lecture topic for my professor's five groups. My main goal isn't to teach, I just want to get students to be as interested in the field as I am. I want to show them what's possible, what awesome magical things have been done in the field, the future we are heading towards using programming and Comp. Sci. Therefore, I would like to pose this question: I have a few topics, materials and sample projects that I would like to talk about: -- Grace Hopper (It is my hope to interest the female programmers in the class. There are never more than two or three per group and they, more than males, are prone to jumping ship and abandoning Comp. Sci.) -- The Singularity Institute -- Alan Turing -- Robotics -- Programming not as a chore or a must, but the idea that we are, at our core, the nexus to which anything anybody does in the digital world is connected to. We are the problem solvers; we assemble all the parts together and we are the ones that, essentially, make the vision a reality. -- Give them an idea for a programming project which, through the help of the professor, could be significant to every student (I want students to not only feel interested in the topic, but they should feel important, that what they do here makes a difference) Do you have interesting topics worthy of discussion, something I can tell the students which they can get interested about? How would you approach the lecture? If you had 90 minutes worth of time to try and get students interested in the project, what would you do?

  • How to make Unity's Dash save the results filtering?

    - by Vagrant232
    The dash can remember the settings for filtered results for the entire session, but not beyond that. Once the profile is logged out and back in the results would reset to their original settings; displaying all the results without filtering. How can I make the results filtering more permanent? IE: How to make the photo lens for instance always show photos from "This Computer" and not from Picasa or Facebook across sessions and not just temporarily?

  • twin view on gnome when monitor is unplugged

    - by james t
    i have a macbook pro which is often connected to a monitor, twin view on gnome works pretty well, but a problem arises when i disconnect the monitor, any window that resided on that workspace is no longer available. another issue is when i start my computer when a monitor is not present, because xorg.conf file has the monitor configuration in it, my mouse pointer often disappears in the other monitor's virtual space, as if it is currently plugged, osx deals with this issue elegantly by refreshing the display every time a plug in/out occurs, is there anything similar that can be done in linux ?

  • what technologies or functionalites can be considered as innovative nowadays?

    - by ts01
    For some unholy reasons (New Year maybe?) I was charged with listing all "innovative things" which my company is doing internally in IT. So, my first question is of course: what can be considered nowadays "innovative" in software, in terms of a/ technologies - like, lets say, cloud computing was 10 years ago or facial recognition 15 years ago b/ functionalities - ie. migration of desktop application to web (last decade) or using voice to control computer (last century) My personal focus is on web, but I am also curious of opinions from others domains.

  • Screen will not load in 11.04 alpha 3

    - by Saad Inam
    After updating from 10.10, there were no problems everything updated fine. I restarted the computer and selected Ubuntu from the boot menu but nothing came. it only shows a a black screen and it allows me to type. I have a feeling that this might be to do with the graphics driver, but how would i get a driver if nothing shows? I have ati radeon 5450 which runs with Catalyst Control Center on Windows. How can fix this?

  • XNA 4.0 Point Vertex Rendering

    - by luis
    I have a buffer of about 134 million particles and a very powerful computer to render them smoothly but I am getting an error when trying to render them as primitive lines it says I cannot render more than around 1 million. I wonder how can I do this, also if is there a better way to render this other than with lines, I'm comfortable with having 1 pixel points or anything as long as the vertices are shown all the time. I'm basically just plotting the points. thanks.

  • How to change Ubuntu from 64 to 32 bit [closed]

    - by Shmaleb
    Possible Duplicate: Can I switch from ubuntu amd64 to ubuntu 32bit My brother installed 64 bit Ubuntu on my moms old PC (dualboot with winXP) and it runs very crappily. It is on Ubuntu 11.10 and I was wondering if there is any easy way of updating to 32 bit 12.04. I know on fedora when you insert instillation media on a computer that already has fedora it asks you if you want to install it over that fedora, is there anything like this for Ubuntu. THANKS!

  • How should I structure my turn based engine to allow flexibility for players/AI and observation?

    - by Reefpirate
    I've just started making a Turn Based Strategy engine in GameMaker's GML language... And I was cruising along nicely until it came time to handle the turn cycle, and determining who is controlling what player, and also how to handle the camera and what is displayed on screen. Here's an outline of the main switch happening in my main game loop at the moment: switch (GameState) { case BEGIN_TURN: // Start of turn operations/routines break; case MID_TURN: switch (PControlledBy[Turn]) { case HUMAN: switch (MidTurnState) { case MT_SELECT: // No units selected, 'idle' UI state break; case MT_MOVE: // Unit selected and attempting to move break; case MT_ATTACK: break; } break; case COMPUTER: // AI ROUTINES GO HERE break; case OBSERVER: // OBSERVER ROUTINES GO HERE break; } break; case END_TURN: // End of turn routines/operations, and move Turn to next player break; } Now, I can see a couple of problems with this set-up already... But I don't have any idea how to go about making it 'right'. Turn is a global variable that stores which player's turn it is, and the BEGIN_TURN and END_TURN states make perfect sense to me... But the MID_TURN state is baffling me because of the things I want to happen here: If there are players controlled by humans, I want the AI to do it's thing on its turn here, but I want to be able to have the camera follow the AI as it makes moves in the human player's vision. If there are no human controlled player's, I'd like to be able to watch two or more AI's battle it out on the map with god-like 'observer' vision. So basically I'm wondering if there are any resources for how to structure a Turn Based Strategy engine? I've found lots of writing about pathfinding and AI, and those are all great... But when it comes to handling the turn structure and the game states I am having trouble finding any resources at all. How should the states be divided to allow flexibility between the players and the controllers (HUMAN, COMPUTER, OBSERVER)? Also, maybe if I'm on the right track I just need some reassurance before I lay down another few hundred lines of code...

  • Why can't my pc and iPhone find each other via Bluetooth?

    - by Torben Gundtofte-Bruun
    I've got Bluetooth enabled on both the computer and the iPhone, and both devices can see my Bluetooth headset so this confirms that Bluetooth itself works. But when I let either device look for other devices, they find nothing (when the headset is off). I'm using 11.10 with all the latest updates. I have not installed any special or additional Bluetooth software; only whatever Ubuntu provides by default.

  • Sync profile/data/software for multiple computers?

    - by ultimatebuster
    Is it possible to sync all the user settings (interface settings, program settings), as well as programs for multiple computers? Data is not as important, though the settings (which is technically data, but not that kind of data, like music, files...) and applications are. Also, it will not sync the drivers. (Example: 1 computer uses bumblebee and the other uses ATI catalyst, and maybe there's different network drivers.. etc.)

  • Suspend fails and I know the module causing it. What can I do?

    - by ch0wn
    My suspend did not correctly since I installed a USB 3 extension card in my PC. Instead of going to S3, the computer just woke up instantly. dmesg gave the hint "usb_dev_suspend+0x0/0x20 returns -2" so I rmmod'ed the "xhci_hcd" module which did the trick. Is there a good way for me to work around this? The builds from the Kernel Mainline PPA did not help, unfortunately, and blacklisting the module is not my favorite option. Where is the best place for me to report this issue?

  • Resources for Entry Level Software Engineering Positions

    - by cdmcnamara
    Hi All, I will be graduating this May with a degree in Computer Science from a well regarded university located in the SF Bay Area. Unfortunately our career services center is terrible and the likely hood of finding a job through them is minimal. I was hoping someone might be able to offer some insight on resources / sites that have a fair amount of entry-level software engineering related jobs? Thanks in advance.
