• My computer stops seeing the other computers on my network

  - by dan

  I'm running Ubuntu 11.04. Sometimes my computer stops seeing the names of the other computers on my network. So I can no longer log into another computer by typing the hosting name e.g. ssh [email protected] I can still log in using the local network IP address. How can I get the first way to work again without rebooting? I know this problem is local to the computer. The other computers on my network can still see one another. But they can no longer see the computer I'm working on, not even by local ip address.

• How To Prevent Your Computer From Waking Up Accidentally

  - by Chris Hoffman

  If you find your Windows computer waking from sleep for no apparent reason, your computer is either being woken up by a hardware device – such as your mouse — or scheduled task set to wake your computer. In some cases, the cause may not be obvious. For example, if your laptop occasionally wakes up for no apparent reason, it’s possible that the floor is shaking a bit, causing the mouse to vibrate slightly and wake the computer. Java is Insecure and Awful, It’s Time to Disable It, and Here’s How What Are the Windows A: and B: Drives Used For? HTG Explains: What is DNS?

• Computer Science Fundamentals - Recommended books

  - by contactmatt

  Hey, I'm looking to see if anyone can recommend any books in fundamentals of computer science. I obtained my associates degree as a programmer/analyst a couple years ago and I know a good amount about programming on the .NET framework. I'm even certified on the .NET 4 framework as a web application developer. However, since I was only able to obtain my associates degree, I was deprived at my college on the low-level basics and operations of computers and basic computer science information. I'm really interesting in learning about the low-level operations of a computer and in programming (bytes, bits, memory management, etc.) Can anyone recommend any good computer science books for someone who is decently experienced in programming? Thank You

• Dual-boot computer won't boot without external hard drive

  - by FrankP

  I have Ubuntu loaded on my external HDD. I tried to unplug the external drive so that this way I could run Windows as the default OS to boot when the computer turns on, but it gives me an error. I need to know how I can make it so that when my computers boots it stops saying Error: no such device: (a whole bunch of numbers and letters) then it says grub rescue>_. If I plug the external HDD in, and I let Ubuntu run the boot process, then it gives me a list of OS's/ HDD's to choose from and Windows 7 is there. The only problem is that I want Windows be my default OS, not the other way around. P.S. I have found that I dislike Ubuntu because I can't even figure out how to install the necessary programs to learn how to start writing Ruby On Rails. So installing it was a waste of my time, in my opinion. Now that I have it on the external hard drive, I will leave it installed though. I just dont want to have to keep that external drive plugged in to my computer all the time. Thank you a ton to whoever can help me! Thank you for the detail'd instructions. I am doing my best to follow you and it makes sense when I read it but, Rescatux is not doing what you said it would. None of the options you said would appear are not there. On my screen there is 4 options when MBR run's none look familiar and when I picked the best possible option based on my educated guesses it said success. I tried to restart my computer and it said Please insert windows recovery disc and hit enter. Problem being I don't have the windows recovery disc. I bought my computer from a local Computer tec and he loads windows on it for you. I have no time to run my compute over to him as sunday is my only day free. I think that I just wrecked my computer in the process of this attempted fix windows refuses to boot now WITH or WITHOUT the HDD. Please help this is getting out of hand

• Setting up Ubuntu on my mother's computer

  - by idealmachine

  Intended use My mother had an old Compaq desktop computer running Windows 98, which she used for occasional Web browsing and playing cards. The name of her card game is Hoyle Card Games 3. Although I had to repair it several times over the last 10 years, it worked fine until it finally died at the end of last year. Hardware specifications A relative brought up a newer computer soon afterward: Operating system: Windows XP Asus K8N motherboard (with broken on-board sound; getting a sound card) Athlon 64? processor (don't remember the clock speed) 512 MB RAM Hope the graphics card works... Replacement sound card will be one of: Ensoniq ES1370 AudioPCI Diamond Monster Sound MX300 (Aureal chipset) Sound Blaster Audigy 2 SE Peripherals HP Scanjet 3400c scanner (USB connected) HP LaserJet multi-function printer (parallel port connected, and printing works with a PCL driver) Same serial mouse as old computer Question I had set up an SSH/VNC connection to allow for remotely working out problems. Or so I thought. A month later, the computer would not boot, rendering the SSH connection useless and an OS reinstall necessary. Unfortunately, I have neither the original Windows disc nor the product key. Unless I were to pay $200 for a full Windows 7 Home Premium license for my computer, I would not be able to re-install Windows XP on hers. I consider myself an advanced Linux user, having used Debian for years. So here are my questions. I have only one day to decide whether to use Ubuntu or buy Windows: A quick search leads me to believe all the hardware listed above is supposed to work with Linux, but am I mistaken? Would Ubuntu/Xubuntu suffice (specify which one if it matters), or would I be better off paying the $200 necessary for Windows XP? Is the card game likely to run on Wine? I believe the minimum system requirement is Windows 95. Failing Wine compatibility, will VirtualBox run fast enough on such a computer (Windows 98 as the guest OS)? Are there any free card games just as good? She plays mainly Bridge, Poker, and Solitaire. Is there any "Large Fonts" option for those with poor vision? The lack of it would be a big disadvantage. BONUS: Although I would probably replace the old mouse upon a move to Ubuntu, is it even possible to get a serial mouse working?

• Can a Windows computer access Pulse sound server on an Ubuntu computer?

  - by Dave M G

  With help I received in this question, I set up all my Ubuntu computers so that they all access a central computer for sound output, using Pulse Audio Preferences. I have some Windows computers as well. I was wondering if it is also possible to make them clients of the sound server computer, so that they will send their sound output over the network to be played by the Ubuntu computer running the Pulse audio sound server. And if so, how?

• Merging photo textures - (from calibrated cameras) - projected onto geometry

  - by freakTheMighty

  I am looking for papers/algorithms for merging projected textures onto geometry. To be more specific, given a set of fully calibrated cameras/photographs and geometry, how can we define a metric for choosing which photograph should be used to texture a given patch of the geometry. I can think of a few attributes one may seek minimize including the angle between the surface normal and the camera, the distance of the camera from the surface, as well as minimizing some parameterization of sharpness. The question is how do these things get combined and are there well established existing solutions?

• Android device connects to my computer, but doesn't play audio over Bluetooth

  - by bi99l35

  I turn on Bluetooth on both my devices and open up Music on my Android. I select a song to play, press the menu button, and tap "Via Bluetooth": I tap on my computer in the "Bluetooth Device Picker": Then it says, under the name of my computer: Connected to media audio Now I should technically be able to play music through my computer, since it "Just Worked" in Kubuntu with Blueman. But nope, something must be up with PulseAudio, because I hear no sound from my computer (I'm running Xubuntu 12.04). The reason I say this is that the devices list in Blueman shows indication of data transfer and it says it's connected, but in the PulseAudio Volume Control has no indication of my Bluetooth device (or Blueman) playing audio.

• My Computer in Ubuntu?

  - by Casey Hungler

  I was wondering if Ubuntu has an equivalent to the Windows feature "My Computer", which lists all available drives/storage devices. Typically, My Computer shows C:, which can be opened to view all of your directories and files. At this point, it is very similar to Ubuntu's Home Folder, but I am looking for something that allows me to view/select all available HDD's/Partitions. Here's my reason: I found a 6gb IDE HDD in my basement, and got an IDE cable for it. My desktop computer has a SATA drive in it, but has an IDE slot, so I wanted to plug it in and see what might be on it. The drive seems to be recognized in BIOS, but I can't find it in Ubuntu to view files, and Ubuntu is the only OS on that particular computer. If anyone has any ideas as to how to view the contents of that drive WITHOUT formatting it or tampering with the contents in any way, I would greatly appreciate your help. Thanks in advance!

• The bottlenecks of any computer, what to look for?

  - by WebDevHobo

  Whether it is a laptop or a desktop, any computer is made up of several pieces of hardware that communicate with each other. Sending data back and forth to ensure that the user gets the desired results. I have seen some theoretical stuff on computers & hardware, but I wonder how it all comes together. CPU RAM Graphics Card L1 CACHE L2 CACHE L3 CACHE FSB ... And all other things. Which is the biggest bottle neck? Why would a person not want/need a big value in one of those categories in certain situations? P.S.: when reading the specs of the i5 750 processor, I came across this description: In place of the FSB, one or more high speed, point-to-point buses called Quick Path Interconnect (QPI) are used, formerly known as Common Serial Interconnect Bus or CSI. QPI features higher bandwidth than the traditional FSB and is better suited to system scaling. What is this, and how does it compare to FSB? EDIT: I am not planning to buy a computer at all. The goal of this question is to understand the internal relation of various hardware pieces, their specific functions and how they work together. For instance, I have heard to a somewhat higher-than-usual amount of L2/L3 Cache can help speed up your computer. What's up with saying that? Also I forgot to mention Hard-disk RPM.

• Determine logged on user on Windows computer from Linux

  - by Justin

  How can I determine who is logged on to a remote Windows XP computer from Linux? I do not have administrator access on the domain or on the remote computer. I can do it from a separate Windows computer using PsLoggedOn -L \\computer from PsTools I've tried using nmblookup -A remotecomputer, but I only see entries for the computer and the domain, not a <03> entry for the user. I've also tried running PsLoggedOn under wine; I get an error: Connecting to Registry of \\computer.company.com... fixme:reg:RegConnectRegistryW Connect to L"computer.company.com" is not supported. I started looking into winexe, but it looks like I would need administrative rights on the remote computer to get it working.

• HTC Android Fails to mount- Mount from computer?

  - by Ben Franchuk

  I Have an HTC Incredible S (S-Off, Rooted, ViperVIVO 1.3.0 ICS) that has seemingly ceased to posses the ability to mount its SD Storage to my computer. For whatever reason, whenever I plug in my device to transfer files from computer to phone and vice versa, the computer, for some reason, cannot actually aces the phone. I get prompted with a window on my phone when I first plug it in, asking me which mode I want to put the device into (Charge mode, tether mode, etc.), and even if I select the "Disk Drive" function, the phone still cannot successfully mount to my computer. The phone itself unmounts itself from the SD and says that the computer is connected, but again, it doesn't work. Is there any way to force mount the device from my computer- either via command or otherwise? This should help in that if I unmount the SD from the phone I should be able to mount it to my computer, from my computer, Correct?

• Manage computer from active directory manager

  - by Ripeed

  Within dsa.mac when I right-click on a computer and choose "Manage", it displays the following error message: Can't find path to computer \\computer.domain.tld. If I try ping computer.domain.tld, DNS translates it to an IP but the computer does not answer. It is right that ping does not answer? Pinging a computer that is not joined to the domain replies as expected. How can I correct this issue?

• Computer won't start up. Stuck on Lenovo splash screen. Help Diagnose

  - by Ace Legend

  I have some (I'm not sure exactly what model) Lenovo 21" IdeaCentre. Honestly, the computer works off and on. I have had problems with it not being able to shutdown, which I fixed. The fan seems to be constantly running, a few other problems as well. Anyway, nobody was using it when all of a sudden it switched to a blue screen. I was in the kitchen, but when I got over to the computer I read the message. It said something about bad drivers, but that is all I saw and then it restarted. However, when it got to the Lenovo Splash screen, nothing happened. I waited there for over 10 minutes, but still nothing. I tried to turn of the computer, but the only way to do it was to pull out the power cable. I then removed all USB devices and tried again. Still nothing. It also won't respond to keyboard input when I try to use enter to interrupt normal startup. My guess is some piece of hardware is damaged inside the machine. However, I have no idea what piece it is. Does anybody have any idea what could be wrong with it? Thanks.

• Remotely start VNC server on computer with no Admin password

  - by Joe M.

  I'm trying to remotely access a particular computer of mine and it seems that VNC has stopped. I can tell that the computer is still running because I can VNC into another machine on the same network and can see my target machine under the Network section in Windows Explorer and can also ping it succesfully. To summarize: I own the target computer I am currently too far to physically access it Remote Desktop Connection feature of Windows is not enabled The computer normally runs a VNC server, but it seems to have stopped The computer is definitely on and connected to the network The computer has no password on the Admin account I can VNC into other computers on the same LAN Given these conditions how can I get into the target to open VNC server, or even just reboot the target (VNC should open on startup)? I have tried PsExec and get "access is denied", and also tried "Connect to another computer.." from the Computer Management console and also get "access is denied".

• Computer turns on and off very quickly, then nothing, then works?

  - by hellohellosharp

  The strange nature of this problem is what is stumping me. I built my computer about 7 months ago using all new parts off of Newegg (not a kit or anything). One day, I wake up and turn on my computer. I press the power button and it turns on, but then back off after half a second. I press the power button again, this time nothing. I continue pressing the power button while at the same time turning the power supply on and off (to try and reset things). The power button still does nothing. But then, after about 5 minutes, WALLAH, it works just fine like nothing was ever wrong. It goes for an entire week working just fine. Then, one morning, the entire process starts again. I press the power button and it comes on and then right back off. I press the power button several times and nothing happens, and then it works again after a couple minutes of trying. What is going on with my computer?

• Computer POST's and draws the BIOS screens very slowly - Motherboard issue?

  - by Ssvarc

  I have a desktop that refuses to boot into Windows. I used Hitachi DFT and the HD came back OK. I then used Memtest86+ and it took hours for the test to run. After 8+ hours it was up to test number 6. I aborted and ran Memtest86. It ran at basically the same speed. I aborted and went to look at the BIOS settings. The computer is running slow at POST. It takes a long time for the keyboard to be recognized, etc. The BIOS settings takes time to be (slowly) drawn on the screen. What could be causing such behavior? EDIT: I gave back the computer a while back without ever discovering the cause so I'm closing the question.

• Migrated from Exchange 2003 to Exchange 2007 - remove old 03 computer account?

  - by TheCleaner

  Migrated from Exchange 2003 to 2007 back in February of this year. I've still got the old exchange computer account in AD. Can I simply delete the computer account or will bad things start happening? I've looked in the Exchange 07 console and don't see the old server listed at all. HOWEVER: we do still have an old CNAME for this old Exchange server pointing to the new one for a few old clients that still have their mail server set to the old name...if that matters at all. I ran "get-exchangeserver" on the new server and the old one isn't listed at all.

• Did I miss anything when checking for passwords? [migrated]

  - by Keltari

  There's a bit of a story to this, so bear with me... I am looking for a new job and came across a posting for a computer forensics position. Its not really my field, but I thought I would apply anyway, just for fun. To make a longer story shorter, they want you to uncover as many passwords as you can find. I downloaded an image and dd'd it to a thumbdrive. The only thing visible was a text file, which contained a password. I knew there had to be more, so I used an undelete utility and found 2 deleted files. First there was another text file with a password - easy. The other was a .pst file which I mounted into outlook. There were some emails with passwords, as well as an email with an image. Another email has a link to a stegenography site. Obviously, there was a file hidden in the image, so I went to the website and downloaded the stegenography decoder. I had to try some of the passwords I had found to get the file to decrypt, and sure enough, there was another text file with a password. I called it a day at that point. Did I miss any other methods?

• How Can I Test My Computer’s Power Supply?

  - by Jason Fitzpatrick

  You’re concerned your computer troubles stem from a failing (or outright fried) power supply unit. How can you test the unit to be sure that it’s the source of your hardware headaches? Today’s Question & Answer session comes to us courtesy of SuperUser—a subdivision of Stack Exchange, a community-driven grouping of Q&A web sites. The Question SuperUser reader Sam Hoice has some PSU concerns: My computer powered off the other day on its own, and now when I push the power button, nothing happens. My assumption would naturally be that the power supply is done (possibly well done) but is there any good way to test this before I buy a new one? How can Sam test things without damaging his current computer or other hardware?   The Answer SuperUser contributor Grant writes: Unplug the power supply from any of the components inside the computer (or just remove it from the computer completely). USE CAUTION HERE (Though you’d only be shocked with a max of 24 volts) Plug the power supply into the wall. Find the big 24-ish pin connector that connects to the motherboard. Connect the GREEN wire with the adjacent BLACK wire. The power supply’s fan should start up. If it doesn’t then it’s dead. If the fan starts up, then it could be the motherboard that’s dead. You can use a multimeter to check if there is power output from the power supply. Adrien offers a solution for readers who may not be comfortable jamming wires into their power supply unit’s MOBO connector: Most well-stocked geek-stores sell a “power-supply tester” that has all the appropriate connectors to plug each part of your PSU into, with spiffy LEDs indicating status of the various rails, connectors for IDE/SATA/floppy power cables, etc. They run ~$20 US. With a little careful shopping you can even find a highly-rated PSU tester for a measly $6. Have something to add to the explanation? Sound off in the the comments. Want to read more answers from other tech-savvy Stack Exchange users? Check out the full discussion thread here.
