  • Windows 7 Start Menu Items Missing

    - by petebob796
    If I click the start menu - All Programs almost all my installed programs seem to be missing from the start menu despite some of them being on the initial regulalry used screen. As far as I can see this has happened within the last week possibly after windows updates installed. Does anyone else have this issue? Anyone know a fix? I have looked in all the locations I can think of for start menu items and can't see them anywhere so it does actually look like they have been removed. I tried as system restore that didn't work.

  • Why would Remote Assistance work but not Remote Desktop?

    - by Craig Johnston
    I have managed to get Remote Assistance working between two XP-Pro machines, but as soon as I try Remote Desktop I can't even get to the login screen without an error which gives a list of possibilities and concludes with "See your network administrator", which isn't very helpful. I have ramped up the security level on Remote Desktop including turning on encryption etc. Could this be the problem? I will only get a few hours on the machine at a time so I need to be well-prepared before I attack this problem again. Any ideas?

  • Cocos-2D asteroids style movement (iOS)

    - by bwheeler96
    So I have a CCSprite subclass, well call this Spaceship. Spaceship needs to move on a loop, until I say othersise by calling a method. The method should look something like - (void)moveForeverAtVelocity { // method logic } The class Spaceship has two relevant iVars, resetPosition and targetPosition, the target is where we are headed, the reset is where we set to when we've hit our target. If they are both off-screen this creates a permanent looping effect. So for the logic, I have tried several things, such as CCMoveTo *move = [CCMoveTo actionWithDuration:2 position:ccp(100, 100)]; CCCallBlockN *repeat = [CCCallBlockN actionWithBlock: ^(CCNode *node) { [self moveForeverAtVelocity]; }]; [self runAction:[CCSequence actions: move, repeat, nil]]; self.position = self.resetPosition; recursively calling the moveForeverAtVelocity method. This is psuedo-code, so its not perfect. I have hard-coded some of the values for the sake of simplicity. Enough garble: The problem I am having, how can I make a method that loops forever, but can be called and reset at will. I'm running into issues with creating multiple instances of this method. If you can offer any assistance with creating this effect, that would be appreciated.

  • Installing any linux distro on new netbook hangs midway

    - by Neigyl R. Noval
    I have just bought a new netbook, Lenovo S110 with a starter Window 7, 32 bit Operating system. I wanted to wipe away Windows and go with Debian or Ubuntu. I have successfully made my USB drive bootable with the Debian net install. The problem is, my computer always hangs up at the start of the installation (with the latter shown on screen). Keyboard stopped responding , and USB was probably not reading (since it was not blinking anymore). I know the bootable USB drive with Debian installer is working since installation works on other netbooks. What should I do to install Linux on my netbook?

  • Set a 2d camera's position so that a building is under the players feet

    - by Potato
    My issue is this: i am making a scrolling game in XNA, and the camera updates based on the players velocity, but the player never actually moves, he is always in the center of the screen. When he hits the top of the building though i want him to always be on top and sink through the texture in a way like this: what i am doing to make this happen is i am just setting his velocity to 0, so its not moving, but the more velocity he hits a building with the more he sinks through it. I also tried setting the buildings position to the plays Bounding Box's bottom, and this achieved the look i wanted but this also resulted in the other buildings rising in the air, because the velocity was still moving (even if i set it to 0). if it was not a scrolling game, this would be not a problem, because you just set the players position to the top of the building, but because the player never actually moves, i actually need to move the camera to the point where the building is under the players feet without the other buildings rising. (Take note this is note a real camera, it is just a class that moves the objects in the world based on the players velocity). All questions are welcome.

  • Graphic Setup tune-up checklist

    - by Click Ok
    I was trying to play the game Warzone 2100 and the games runs fine, with nice speed, but the screen stays with a horizontal lines "flickering"... My PC have a integrated GeForce Go 6100 vga. Ok, not a powerfull vga, but it's not the end of the world to run a "simple" game like this (compared with another games that ask you send your eyes to purchase a expensive vga). So, I think that the problem can be of the configuration of my machine. I use it in first instance for programming jobs, so I underpay attention to video setup. I would like about a checklist to know if my PC is "ready" to games. By example, I know that I need: Lastest vga drivers Updated DirectX and OpenGL What you suggest? There is too some good programs to test performance and suggests improvements in the system? Thank you! PS: I'm using Windows 7

    I have installed Windows and Ubuntu side by side. I created a 10GB partition for the Ubuntu installation. During the two months I've been using Ubuntu I have installed some software. Now it's not starting. When I boot up it says that there is no diskspace so it could not be started . What can i do now? When I boot up all I get is a black screen terminal with a $. Please help me with a command to uninstall some programs and start using Ubuntu or any other way to get rid of this message.

  • "Punch card" application

    - by icelava
    Our main-con manager is looking for a "punch card" type of attendance-logging application. We need to take attendance every day, and the most "automatic" method is simply to track when people unlock their Windows desktop screen (not logon, because many simply leave the computer on indefinitely), and report to a remote location/repository, where the administrator will be able to observe which users unlocked their screens each day. Has anybody come across such an application suite? It likely has to be a Windows service so that it operates regardless of who is logged into the system.

  • How to properly uninstall/reinstall Ubuntu One on Windows XP?

    - by user73303
    I had previously installed an Ubuntu One client as a test on a Windows XP machine. Now I wanted to change the account for the client to a production one but had problems changing the email address so decided to do a reinstall. Ran uninstall. Downloaded ubuntuone-3.0.2-windows-installer.exe. It downloads, goes through the unpacking/install – strangely some of the messages say updating as if it was replacing something that was already there. I do not get the setup/signin screen. There is no ubuntu% processes running. The Program files/ubuntuone directory exists with data and dist folders. The U icon is on the desktop – pointing at ubuntuone/dist/ubuntuone-control-panel-qt.exe but this does not run. Ran uninstall again, deleted Program files/ubuntuone directory, removed any ubuntu entries for registry, rebooted. Downloaded install again - exactly the same as above. How can I uninstall Ubuntu One to get a clean reinstall? Or force the install to continue after downloading/unpacking?

  • Authentication error in LTSP client

    - by sat
    I am building a LTSP server with LDAP authentication for LTSP Clients. I have configured LDAP server also. When I try to login from LTSP client in GUI, I am getting No response from server, restarting. Then, It's restarting the GUI and comes to the login screen again. I thought that there could be a problem with LDAP authentication. But, When I try to login from Alt+Ctrl+F1 terminal in LTSP client, it is logged in successfully with LDAP user. LDAP Server and authentication is working fine. Even, after executing the below commands, still I am getting the same error. ltsp-update-sshkeys ltsp-update-kernels ltsp-update-image --arch i386 Whether I need to configure anything for GUI login from LTSP Client? How to fix this issue?

  • What's the typical latency for key strokes using an ssh connection on a local wifi network?

    - by dan
    I develop software on a Macbook Air 1.6 Ghz but find running Rails test suites and generators on this computer very slow. I'm thinking about buying a Linux tower to put on my local wireless network to do my Rails development on. I would want to use my Macbook Air and ssh into the Linux box and do my development with Gnu Screen, vim, etc. Can I expect the keystroke and echo latency for a ssh session between two machines on a local wireless network to be negligible? Does anyone develop using this kind of local setup?

  • How can I automate restarting a vmware vm

    - by Stu
    I have a vm that does nothing but run magic jack. Magic jack doesn't run perfectly in a vm. It works great for days then randomly the vm reboots. except it doesn't come up clean. It gets to the windows splash screen and hangs spinning the cpu. I don't care how I solve the problem (although not crashing in the first place would be ideal) but I just need the vm to reboot cleanly when it does crash. Is there a windows registry setting I can say "on crash, reboot" or something like that?

  • some keys don't appear in xev

    - by sazary
    i can't change my screen brightness by pressing brightness keys on the keyboard, but they change through /sys/class/backlight/acpi_video0/brightness. so i started to diagnose the issue, ran xev and trying to see what happens when i press Fn+F5 or Fn+F6 which are brightness controls, and xev didn't show anything. i must note that it notifies my when i press volume controls, for example. are F5 and F6 keys working? yes, but not when i press them with Fn key. do i have any entry in xmodmap for brightness? yes: keycode 232 = XF86MonBrightnessDown NoSymbol XF86MonBrightnessDown keycode 233 = XF86MonBrightnessUp NoSymbol XF86MonBrightnessUp what's happening? and what should i do to correct it? i'm using vaio s series laptop with kubuntu precise on it. thanx ;)

  • After installing Windows 8, boot hangs before BIOS setup

    - by Joe Purvis
    I have an Alienware M15x, 940MX processor, 16 GB RAM, 512GB M4 SSD, and I was running Win7 64bit. I backed up the disk and ran Win 8 setup. Setup appeared to go well through multiple reboots. After the last reboot, it simply stopped after POST at "Press F2 for bios setup". I have tried powering off, reducing RAM to one stick, removing MOS battery. Now, it gets to the screen with "Press F2 for setup" and "Press F12 for boot options". If I press F2, I get a single beep only. If I press F12, nothing. I cannot get into the BIOS to change boot options to boot from another disk and restore. I do have the latest BIOS. I am going to try replacing the CMOS battery, but I don't think that is likely to help. The computer has been fast and very reliable until now.

  • Remote Desktop to a user while still logged on

    - by Jonathan
    Is there a way to connect remotely to another user while there is a user still on the same PC. So one PC with users and both of them logged in at the same time, one locally and one remotely? Sorry i didn't explain my question very well, I don't mean 2 users viewing the same screen. I mean 2 user accounts. Say UserA is sitting at the desk on his account. and then UserB is on his account account but it remotely connecting to it. So they both have different desktops in front on their respective screens.

  • How to get Nvidia 555M working on Ubuntu 12.10 (drivers, optimus, cuda)?

    - by bluudz
    I'm trying for few days to get my GPU working properly on Alienware M14x with GPU NVidia 555M, but I have no luck at all. After fresh ubuntu install I did follow the guide here NVIDIA Optimus and Ubuntu 12.10 and istalled Bumblebee without problems. Tested glxspheres/optirun glxspheres both working fine. Now I was continuing to install CUDA as is said here How can I get nVidia CUDA or OpenCL working on a laptop with nVidia discrete card/Intel Integrated Graphics? but I'm getting: Driver: Not Selected Toolkit: Installation Failed. Using unsupported Compiler. Samples: Installation Failed. Missing required libraries. I did not select the driver as I though Bumblebee installed driver already. How should I proceed? And also at what point is the NVidia driver being installed and how can I try its working? Bumblebee seems to be installing the driver, CUDA wants to do the same, its all a bit confusing really. Sorry if its lame question, but I would really want to at least get graphic card and second screen working.. Thank you for any help.

  • is wisdom of what happens 'behind scenes' (in compiler, external DLLs etc.) important?

    - by I_Question_Things_Deeply
    I have been a computer-fanatic for almost a decade now. I've always loved and wondered how computers work, even from the purest, lowest hardware level to the very smallest pixel on the screen, and all the software around that. That seems to be my problem though ... as I try to write code (I'm pretty fluent at C++) I always sit there enormous amounts of time in front of a text-editor wondering how every line, statement, datum, function, etc. will correspond to every Assembly and machine instruction performed to do absolutely everything necessary for the kernel to allocate memory to run my compiled program, and all of the other hardware being used as well. For example ... I would write cout << "Before memory changed" << endl; and run the debugger to get the Assembly for this, and then try and reverse disassemble the Assembly to machine code based on my ISA, and then research every .dll, library file, linked library, linking process, linker source code of the program, the make file, the kernel I'm using's steps of processing this compilation, the hardware's part aside from the processor (e.g. video card, sound card, chipset, cache latency, byte-sized registers, calling convention use, DDR3 RAM and disk drive, filesystem functioning and so many other things). Am I going about programming wrong? I mean I feel I should know everything that goes on underneath English syntax on a computer program. But the problem is that the more I research every little thing the less I actually accomplish at all. I can never finish anything because of this mentality, yet I feel compelled to know everything... what should I do?

  • Upgraded from 11.4 to 11.10, There was an error, now the system won't initiialize

    - by Eric
    This morning the system gave me a message that my Version (11.4) was no longer supported, and I took the 'upgrade' option (- 11.10). While installing the various components I encountered a message to the effect that the there was an error and the system may have become unusable. Among the messges: E:Sup-process /usr/bin/dpkg received a segmentation fault...returned an error code (1). I was given an option to do several things, one of which seemed to mean that it would attempt to roll back to the previous version (the default), which I took. After the process ran it said the upgrade process had finished, but there were errors. I attempted to initialize a console so I could enter ubuntu-bug update-manager /var/log/dist-upgrade, per the instructions I received when I received the error message, but the console failed during initialization. I restarted the machine, and the screen has stopped with the following contents: * Starting bluetooth * Stopping save kernel messages * Starting CUPS printing spooler/server * PulseAudio configured per-user sessions saned disabled: edit /etc/default/saned $starting up Cisco VPN daemon *Starting anac(h)ronistic cron *Stopping anac(h)ronistic cron Each of these steps followed by [ OK ] What are my options? Any help appreciated!

  • Windows 8 taking 4+ mins to shutdown

    - by arnab321
    I did a fresh installation of Windows 8 64 bit, build 9200 (released on aug 16th). I installed the drivers and some basic softwares like NetBeans, mingw, iis server and php. For the first few times, it was restarting normally. But then at shutdown, it would show the shutdown screen for some seconds and then turn black for about 4 mins (similar to what happens at hibernation). I disabled the "fast startup" option in power options, but the problem still persists. Windows 7 and Ubuntu shut down normally. specs: 4gb ram, 750 gb sata hdd, solved by installing Windows Updates released during October. It was a serious bug in the OS, afaik. Now even hibernate takes upto 30 secs max. Still, win 8 is too buggy for release.

  • Review: Logitech t620 Touch Mouse and Windows 8

    - by Tim Murphy
    It isn’t very often that I worry much about hardware, but since I heard some others talking about “touch” mice for their Windows 8 machines I figured I would try one out and see what the experience was.  The only Windows 8 compatible touch mouse that they had in the store was the Logitech t630 Touch Mouse.  At $69 it isn’t exactly a cheap purchase. So how does it work with Windows 8.  First it works well as a normal mouse with touch scroll capabilities.  Scrolling works both horizontally and vertically.  Then you get into to the Win8 features, all of which are associated with the back 2/3 of the mouse.  If you double-touch-tap (not depressing the internal button) it acts as a Windows home screen button.  The next feature is switching applications.  This is accomplished by dragging a finger from the left edge of the mouse in.  Bringing up the Windows 8 open apps list is the same movement as on the table where you drag in from the left and then move back to the right.  The last gesture available is to bring up the charms.  This is performed by dragging in from the right side of the mouse. There is a certain amount of configurability.  You can switch dominant hand configuration as well as turn on and off gestures as shown in the screenshot below. It is nice that they kept the gestures similar to the table gestures.  Hopefully future updates to the drivers will bring other gestures, but this is definitely a good start.  It would be interesting to also compare this to the Microsoft Touch Mouse and see if there are additional gestures such as app close and for the app bar. del.icio.us Tags: Logitech,Windows 8,Win8,t620,Logitech t620 Touch Mouse,Gesture

  • How can I have sound output before logging in?

    - by ??O?????
    I have a machine (Ubuntu 11.10) that I would like to have it play audio (typically through an amplifier), but the machine should be headless (where its final placement will be). I will control what is played through ssh. However, there is no sound output until I login to the graphical console. At first I thought it was an issue with pulseaudio, so I promptly removed it to use the default ALSA, but I have the same issues. I ssh to the machine, I run alsamixer and get the typical cannot open mixer: No such file or directory error (while /proc/asound/cards display correctly what I have). If I login on the graphical console, alsamixer works fine in the ssh session, and I have sound output. I logout, and then alsamixer stops working. So something runs (Xsession perhaps?) when I login that enables sound output, and gets disabled when I logout. I remember in older versions of Ubuntu, there was a drum roll when the machine showed the login screen; that is not the case anymore. Perhaps if I somehow can enable that drum roll, I'll have fixed my problem too. In any case, the question I ask is what the title says.

  • Unable to access my own websites from our home

    - by user2521866
    Not sure if this is the right place to ask, but i'm gonna have a shot at it. I host a couple of websites with a webhost in the Netherlands. For a couple of days now, i've been unable to connect to them from my home network. When using tracert in the cmd screen, i'm getting a timeout after about 4-5 hops. It seems fine accessing the website from anywhere, except my home network. Other PC's around the house also fail to open the websites. I've tried 'flushing my DNS' as seen in some other topics, but to no avail just yet. One of the websites: http://bit.ly/1hbqs4J I've contacted my host about it as well, but no response yet. Trying to take control of the situation myself now for as much as I can. Regards, Dave

  • handle 50-100 million rectangle in AutoCAD

    - by Wang
    I have huge problem when I try to get large array. For example, I have something like 10000x10000 or 5000x5000 rectangles. It is almost impossible to do anything because the screen just got frozen up. It is impossible to contain so many objects in one array. So I had 100x100 rectangle array as xref then array the xref again. It ate up about 12GB RAM. I guess this is the problem. Can anyone give me any suggestions can achieve the same structure but without freezing the computer?
