• Unable to connect to network

  - by user33750

  Hey guys, I have a question. I have been having problems connecting a new netbook to my network at home. I have an Asus Eeepc 100HAB. I have tried to run a repair on the connection, uninstalled and re-installed the network card, made sure all of the drivers are up-to-date as well. Two caveats: I have a laptop that I recently switched to a wired connection because it wasn't connecting to the network as well, and the netbook connects to an unsecured network i found just fine, only having a problem getting into my home network. Passwords are correct, and the computer where the connection originates from is working fine as well. Any ideas?

• Dual External Monitors Through Docking Station on ASUS G73JW-XT1

  - by user60695

  I am getting an ASUS G73JW-XT1; and I would like to set it up so that I can plug it into a docking station at my desk, and use 2 external monitors (not the laptop display and an additional monitor). The computer supports a DVI and HDMI output, but I cannot find any docking stations that will support two external displays, as well as audio ports and USB ports for other peripherals. Does anybody know of a specific docking station that will do this, or another workaround without having to plug in several things to my laptop every time I bring it to my desk?

• Mouse Icon Distorted on Secondary Display

  - by Nathan Taylor

  I have a strange issue with a dual monitor, extended desktop setup where the mouse is always fine on the primary monitor, but sometimes when I move to the secondary display the icon becomes garbled and distorted (sometimes it just looks like a vertical line, instead of a pointer). If I move the mouse back and forth rapidly between primary and secondary displays the level of "garbledness" of the icon will change and sometimes go away completely. If I switch the display settings and set it to "Duplicate Monitor 1" then I end up with a garbled icon on the primary display and an accurate one on the secondary. Very annoying. Computer is Windows 7 Ultimate with an HD8750 and the newest video drivers. Monitors are two Dell 24" displays connected via DVI cables. I have also tried VGA cables.

• Accessing second hard drive

  - by Jonathan

  Hi, So I recently installed Ubuntu 10.10 64-bit on my computer. I installed it on my 60gb SSD hard drive, and in the installation it never acknowledged the existence of my second hard drive. The hard drive that I keep all my files on, and which I want to make my home folder if I can, is a Western Digital Caviar Black 1TB SATA 6Gb/s 64MB cache (WD1002FAEX). I've read the following: https://help.ubuntu.com/community/Mount but honestly cannot work out how to access the hard drive from my Ubuntu installation. I did have Windows 7 64-bit prior to installing Ubuntu. I have backed up all the files on the hard drive, but if I could just access them straight off that would be super cool. Does anyone know how I can use the second hard drive? Thank you for your help EDIT: The following directories are currently in my /dev/ folder: ati/, block/, bsg/, bus/, char/, cpu/, isk/, input/, mapper/, net/, pktcdvd/, pts/, shm/, snd/, and usb/ EDIT: Result from sudo fdisk -l Disk /dev/sda: 60.0 GB, 60022480896 bytes 255 heads, 63 sectors/track, 7297 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x000d2dfd Device Boot Start End Blocks Id System /dev/sda1 * 1 6994 56174592 83 Linux /dev/sda2 6994 7298 2438145 5 Extended /dev/sda5 6994 7298 2438144 82 Linux swap / Solaris

• Share internet with my phone?

  - by Kenneth Cochran

  Most people want to use their cellphone as a modem for their computer, commonly referred to as 'tethering'. I'm actually interested in doing the opposite: Sharing my landline internet connection(which is much faster than any 3G service) with by cellphone. My phone is a Verizon BlackBerry Curve 8330 and it has USB and bluetooth connections. I know both USB and Bluetooth are capable of supporting tcp/ip traffic what's not so clear is: Is IP over USB or Bluetooth standardized? Is it supported on my phone? Has my cellphone company crippled my phone to prevent me from using it?

• Metro Apps on Windows 8 aren't working with static IP behind auth proxy

  - by Kamal

  In Windows 8 Professional, Metro Apps and Windows Update do not work with static IP settings behind authenticated proxy server. They work with DHCP on the same proxy settings (we have DHCP for wifi and static IP for LAN, both using the same proxy server). IE, Chrome and other desktop apps work nicely with both. Metro apps worked with an auth proxy (DHCP only), when I changed their proxy settings from the "edit group policy" option: Start → Settings → Edit Group Policy → Computer Configuration → Administrative Templates → Network Isolation → Internet Proxy for Apps How can I fix this?

• Missing driver ASUS PCE-N53 11n N600 PCI-E Adapter

  - by oyse

  I have problems with getting an Asus PCE-N53 11n N600 PCI-E Adapter card to work on my desktop computer. As far as I can tell no drivers are installed for the card.

• Backup and restore.

  - by Xavierjazz

  I have a Thinkpad T60 with a 150GIg internal hard drive. XP Pro SP3. I also have a similar hard drive that used to be in another laptop connected via USB. It contains only data. I have cleared out a lot of duplicate files and now would like to back both up. I have Retrospect and a brand new 1Tbyte drive for this purpose. Can I back up the whole computer (both drives) but, in case only one fails, can I just restore that drive or do I have to restore both drives at the same time? I don't understand how partitions work so might I be able to partition the 1T drive and restore each smaller drive independently? Thanks.

• Downloading videos from a flash website

  - by Mimi

  There are those plugins that can capture flash videos from websites like Youtube and others. There's also the browsing cache which keeps the videos and I can copy them somewhere else and have them stored on my computer. I know of these, but how can I download a video from a website that (I think) is all flash because the address doesn't change wherever you navigate to and so it stays the same when you play a video that's on the website? No plugin I've tried (realplayer, ant video downloadr, IDM) have worked with it and nothing gets cached from that website.

• HDMI Sound for HTPC

  - by Brent Arias

  I have the (perhaps) the same problem as stated in this other HDMI sound to HTPC question. I tried the advice of clicking on the speaker in the system tray. I can see the HDMI audio device I want to use. That device claims to be functioning properly. But there is no sound, and it won't let me select it as the active audio device. When I click on the troubleshooter, it says that there are no speakers connected. I would think this is because my computer us unable to pipe sound through the video card (preventing the HDMI from carrying it), except that it truly claims that it has an HDMI sound device that is working correctly. So I'm not sure what is wrong at this point. Thoughts? My system is Windows 7 x64. In case it makes a difference, the video card I'm using is this GeForce GTX 560

• Encryption of external HDD -- accessible from windows without installation

  - by Rainer

  I would like to use encryption on my external HDD but I would like to be able to access the encrypted data from Windows as well. As suggested in other questions, TrueCrypt is one option here, or I am using momentarily encfs, which is not available for Windows. But my question goes further: I would like to be able to access the encrypted partition from Windows without installation as I will be using it from different Windows machines for which I have no administrator access. My main OS is Linux and I have full root access to that computer. Is there a full disk or file based encryption which I can use cross platform and which does not require installation under Windows? ADDITION: It seems that TrueCrypt provides a portable mode which fulfills my requirements partly: http://www.truecrypt.org/docs/?s=truecrypt-portable, but still the TrueCrypt driver needs to be installed by an administrator... pitty Thanks

• Stacks in C++

  - by MarkPearl

  So some more basics… One of the things you will be taught at any college after conquering arrays is different derivatives of collections. Stack is one of the simplest of those and very useful… A stack is a LIFO (last in first out) data structure and has at least two basic method calls – push & pop. Push, “pushes” an item on the top of the stack. Pop, removes the top most item off the stack. Because all elements on a stack are of the same type, one can use an array to implement a stack or a linked list. With the array based approach, the first element in a stack would be the first element in the array, the second on the stack would be the second on the array, etc. One limitation with an array implementation of a stack is that unless the array is dynamic, one would have to have a preset max stack size (based on the bounds of the array). Linked lists is another approach that gets past this boundary by allowing you to dynamically grow or shrink a collection of data. Stacks have many applications… a typical computer science example would be Postfix Expression Calculator, where the LIFO principle is maintained.

• Is there such thing as a "theory of system integration"?

  - by Jeff

  There is a plethora of different programs, servers, and in general technologies in use in organizations today. We, programmers, have lots of different tools at our disposal to help solve various different data, and communication challenges in an organization. Does anyone know if anyone has done an serious thinking about how systems are integrated? Let me give an example: Hypothetically, let's say I own a company that makes specialized suits a'la Iron Man. In the area of production, I have CAD tools, machining tools, payroll, project management, and asset management tools to name a few. I also have nice design space, where designers show off their designs on big displays, some touch, some traditional. Oh, and I also have one of these new fangled LEED Platinum buildings and it has number of different computer controlled systems, like smart window shutters that close when people are in the room, a HVAC system that adjusts depending on the number of people in the building, etc. What I want to know is if anyone has done any scientific work on trying to figure out how to hook all these pieces together, so that say my access control system is hooked to my payroll system, and my phone system allowing my never to swipe a time card, and to have my phone follow me throughout the building. This problem is also more than a technology challenge. Every technology implementation enables certain human behaviours, so the human must also be considered as a part of the system. Has anyone done any work in how effectively weave these components together? FYI: I am not trying to build a system. I want to know if anyone has thoroughly studied the process of doing a large integration project, how they develop their requirements, how they studied the human behaviors, etc.

• Seasgate GoFlex NAS + Horrible Speed = Bad Experience

  - by Jon H

  I am having issues with transfer speeds from my desktop PC to my NAS. I have my NAS hooked up to a Gigabit Gateway as well as my Desktop with Cat 5e. I see up to 4.0 MB/Second Transfer Rates, the normal is about 2.5 MB/Seconds. There is 3 Partitions on my NAS, Public, Private, Backup. When I transfer from Private to Public I see the speeds above. If its under the same partition almost instant. I was wondering if the speeds I am seeing is in due to my Computer or the NAS. I was looking into building my own Media Server in due to these horrible speeds. Is their anything I can do in the mean time to speed this up?

• Commercial NAS RAID1 disks moved to Software Raid system?

  - by Rolnik

  I've got a couple of commercial NAS boxes and I'm wondering if they (ReadyNas duo, DLink DNS-323) or any other NAS is suitable for having their RAIDed disks moved to a software-based NAS. To be specific, I'm a big fan of the (largely) Debian-based Ubuntu. Can the aforementioned NAS drives be migrated to Ubuntu (e.g. using the mdadm Linux command)? Secondly, is there any commercial NAS that can be migrated over? Incidentally, here is a link to somebody who succeeded in a migration: http://www.linuxquestions.org/questions/slackware-14/moving-raid1-drives-into-computer-with-same-md-numbers-862312/ My specific scenario I'd like to prepare for, is the eventual (sudden) death of one of the NAS motherboards.

• Cannot access to any Windows share including localhost

  - by user21936

  I can't access any share from my operating system, including \\localhost and \\127.0.0.1. I have Windows 7. NetBIOS over IP is enabled, other computers in the network can access my shares and other computer's shares, but my operating system cannot access any share. I have installed Windows XP within VMware, and the virtual Windows XP can access all shares including the host shares. I can communicate in other ways like TCP, HTTP and gaming, but not access shares. How to solve this problem?

• Add a hook to run when NetworkManager connects

  - by rplevy

  What would be a good way to make a script run every time my computer connects to the network in Ubuntu? Would I somehow use dbus to do this? Background: when I'm on the train I run a short Perl script to click a button on the splash page. That way I can immediately use the internet without having to manually visit a pointless website. My script is a near-perfect solution, but it would be perfect if it could run automatically any time I connect to the network.

• What are `Developmental Milestones` for programming skills?

  - by Holmes

  I studied in the field of Computer Science for 6 years, bachelor's degree and master's degree. I have studied all the basic programming like C, Java, VB, C#, Python, and etc. When I have free times, I will learn new programming languages and follow new programming trends by myself , such as PHP, HTML5, CSS5, LESS, Bootstrap, Symfony2, and GitHub. So, if someone wants me to write some instructions using these languages, I'm certain that I can do it, not so good but I can get a job done. However, I don't have any favorite programming language. Moreover, I also have studied about algorithms, database, and etc. Everything I just wrote so far seems that I know a lot in this field. In fact, I feel I am very stupid. I cannot answer 80% of the questions on SO. In spite of those languages??, I have studied. Perhaps it is because I have never worked before. As there is the Developmental Milestones for children, which refers to how a child becomes able to do more complex things as they get older, I would like to evaluate the same thing but for programming skills. What are the set of functional skills or age-specific tasks that most programmers can do at a certain age range? In order to evaluate myself, I would like to ask your opinions that all of the skills I mentioned above, are they enough for programmers to know when they are 25 years old? What are your suggestions in order to improve the skills in this field?

• Is a ext3 Linux filesystem byte order independent

  - by Lothar

  I have a good old HP-C3700 Workstation with PA-RISC CPU here that I would like to use as a subversion server for a very large repository. I just worry what happens if the workstation dies (everybody who knows this computer knows that it is running like an Abrams tank and unlikely to happen in the next decade). I'm using Debian Linux on this system. If the mainboard dies can I just plug the SCSI drive into a PC and read the files from a normal Intel Linux PC? Which software RAID levels would be safe?

• install grub on pendrive containing linux installation, making it system independent

  - by arpit

  i have a win7 system and i want to install debian 6 on usb flash drive. the problem is grub loader. i want to install the grub loader on usb itself, so i can just plug in the pendrive in any computer and boot to deb6. so in effect making the flash drive an independent system. i tried it earlier, but ended up with grub loader needing me to insert the pendrive every time to give me boot options to even boot the win7 system, even though it was on primary hdd. so is there a way to turn the pendrive into full linux system with own boot loader, which can automatically detect os in the system i plug it in and be able to boot any of them. totally, self sufficient and system independent; making the pen drive so that it only needs a host system to run the os it carries. thank you, waiting for replies.

• Why cant i install ANY operating system??

  - by Ranhiru

  I tested the memory and i tested the hard disk and everything is fine! Mini XP booted from Hirens Boot Disk works :( I tried Windows 7, Windows XP SP3 and even Ubuntu 10.04 :( All Operating Systems boots up to the point where they can load necessary files to start the OS and then resets the laptop Windows 7, only up to the point where the Windows Loading Animation is happening Ubuntu, only up to the point where the loading is done, shows a small screen and then goes to a blinking cursor and thats it... it keeps on blinking and sometimes resets the computer Windows XP SP3, loads all the drivers and everything and then the point where i should be able install the OS, it simply resets the laptop :( I have used the word reset instead of restart because the laptop completely turns off and then only turns back in Any solutions would be greatly appreciated

• Are there any concrete examples of where a paralellizing compiler would provide a value-adding benefit?

  - by jamie

  Paul Graham argues that: It would be great if a startup could give us something of the old Moore's Law back, by writing software that could make a large number of CPUs look to the developer like one very fast CPU. ... The most ambitious is to try to do it automatically: to write a compiler that will parallelize our code for us. There's a name for this compiler, the sufficiently smart compiler, and it is a byword for impossibility. But is it really impossible? Can someone provide a concrete example where a paralellizing compiler would solve a pain point? Web-apps don't appear to be a problem: just run a bunch of Node processes. Real-time raytracing isn't a problem: the programmers are writing multi-threaded, SIMD assembly language quite happily (indeed, some might complain if we make it easier!). The holy grail is to be able to accelerate any program, be it MySQL, Garage Band, or Quicken. I'm looking for a middle ground: is there a real-world problem that you have experienced where a "smart-enough" compiler would have provided a real benefit, i.e that someone would pay for? A good answer is one where there is a process where the computer runs at 100% CPU on a single core for a painful period of time. That time might be 10 seconds, if the task is meant to be quick. It might be 500ms if the task is meant to be interactive. It might be 10 hours. Please describe such a problem. Really, that's all I'm looking for: candidate areas for further investigation. (Hence, raytracing is off the list because all the low-hanging fruit have been feasted upon.) I am not interested in why it cannot be done. There are a million people willing to point to the sound reasons why it cannot be done. Such answers are not useful.

• VLC Ati Radeon 6870 Ubuntu 12.04 image skewed flicker

  I'm running Ubuntu 12.04 with ATI Radeon 6870 connected to my 40' Sharp TV. The video image is slightly jigged, like breaking a bit and slightly delayed. It just isn't smooth.

I tried to run the same video with my mac laptop and on the tv with the same connection cable and it was running smoothly. i tried changing the video output in VLC to x11, increase caching, h264 skip loop filter to all, increase monitor refresh rate although it's already at 60 and it's an LCD tv. this is my xorg.conf : Section "ServerLayout" Identifier "amdcccle Layout" Screen 0 "amdcccle-Screen[3]-0" 0 0 EndSection Section "Module" Load "glx" EndSection Section "Monitor" Identifier "0-DFP9" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" Option "PreferredMode" "1920x1080" EndSection Section "Monitor" Identifier "0-DFP10" Option "VendorName" "ATI Proprietary Driver" Option "ModelName" "Generic Autodetecting Monitor" Option "DPMS" "true" Option "PreferredMode" "1280x1024" Option "TargetRefresh" "60" Option "Position" "0 0" Option "Rotate" "normal" Option "Disable" "false" EndSection Section "Device" Identifier "amdcccle-Device[3]-0" Driver "fglrx" Option "Monitor-DFP9" "0-DFP9" BusID "PCI:3:0:0" EndSection Section "Screen" Identifier "Default Screen" DefaultDepth 24 EndSection Section "Screen" Identifier "amdcccle-Screen[3]-0" Device "amdcccle-Device[3]-0" DefaultDepth 24 SubSection "Display" Viewport 0 0 Depth 24 EndSubSection EndSection

• Installing a 3.5" hard drive in a 2.5" bay?

  - by Javawag

  I know this question seems ridiculous, but my server (actually a Mini-ITX computer) has a 2.5" hard drive bay and an empty CD-ROM bay underneath it. If I removed the hard drive bay, I could probably mount a 3.5" hard drive in the CD-ROM bay which is unused... I know it's a big of a kludgy way to do things but it does mean upgrading the hard drive to 2TB is much cheaper. My question is: are the power requirements of a 3.5" disk the same as 2.5" one? I know the connectors physically will still fit, but I don't want to destroy my server!
