  • Ubuntu (11.10) fails to connect to wireless network

    - by Tal Galili
    I just installed ubuntu 11.10, and tried to have it connect to the internet. I use a wireless USB stick by edimax (it is called IEEE802.11b/g/n nano USB adapter or also EW-7811Un). My problem is that Ubuntu seems to be able to use the USB to see the networks around me, but when I try to connect to my network - it just keeps trying and failing. I am connected to the internet through a 300M Wireless N Router Model No. TL-WR841N / TL-WR841ND Can you please advise on how this can be resolved? Thanks!

  • Real performance gain from faster IDE or SATA hard drive?

    - by raw_noob
    How much of a real-world performance gain would you expect from: replacing a 5400rpm IDE HD with a 7200rpm IDE HD? replacing a 5400rpm IDE HD with a SATA-150? It's assumed that the drive in question is both the system drive and the only drive. A modest AMD Sempron-based home computer with adequate DDR memory running Windows XP Home SP3. Thanks for looking.

  • How to install Windows 8 in a system which has Ubuntu 12.04 and Windows 7 installed already?

    - by Vignesh Palani
    I have a system in which I have installed Windows 7 first. I then installed Ubuntu 12.04 to the system. Now, the boot manager is GRUB Loader and everything works fine as Ubuntu detected that Windows 7 has been installed already. Now, I would like to install Windows 8 too. I plan to install using a bootable USB stick(doesn't matter which medium I prefer though. Does it? ). I have done some research and all the materials I can get state that I cannot practically install Windows 8 after Ubuntu and get all the three OSs to run. Can you help? I want all the three Operating systems to work perfectly.

    - by evolvd
    Laptop: HP Compaq 6710b I can boot from usb just fine with the following usb flash drives: Cruzer micro 4GB HP 4GB The flash drive that will not boot: Flash Voyager 8GB To knock out variables I did the following: Using Hard Disk Low Level Format Tool I performed a low level format Full erase with Flash Memory Tookit In windows 7 I formated the drive to fat32 Used USB-Boot-Tester to write to the drive Also used uNetbooting with various distros to see if that would make a difference My guesses on what could be preventing the drive from booting: The laptop does not support booting to usb flash drives larger than 4GB The drive is defective in some way

  • Are there any benefits to using a Distributed vSwitch for iSCSI?

    - by dunxd
    I am designing our vSphere farm - we'll be migrating from ESX 3.5 to 4.1. I plan to set up a new farm using ESXi 4.1, and move the Virtual Machines on the 3.5 farm into it by shutdown, then import. In ESX 3.5 there is no distributed networking, so each host has a vSwitch connected to my SAN NICs, and a port group for the vmkernel. In vSphere (ESXi 4.1) I have the extra option to set up a distributed vSwitch and distributed port groups for vmkernel to access iSCSI storage. Is there any benefit to this, or should I stick to non-distributed networking for iSCSI.

  • Windows 64bit Sandboxing software alternatives

    - by Pacifika
    As you might know sandboxing software doesn't work in 64bit Windows due to patchguard. What are the alternatives for a person looking to test untrusted / temporary software? Edit: @Nick I'd prefer an alternative to VMs as I'm not happy with the extended startup time, the extra login sequences and the memory overhead that accompanies booting a VM solution to test something out ocassionally as a home user. Also it's another system that needs to be kept secure and up to date.

  • How does Notepad++ know to recognize the HTML and CSS in PHP files? Can I do this with PSP files?

    - by Andrew Alexander
    I am trying to get Notepad++ to recognize PSP (Python Server Pages) files. I've got it to recognize Python (by adding PSP to the ext= section), however it doesn't seem to understand that Python is only within the <% %> and <%= %> sections. I want it to parse HTML, CSS, Javascript and possibly even PHP (though if I am using PSP, I'd probably stick with that) as well, showing all the colors, etc, that would normally be associated with it. How do I go about that?

  • Looking for Ubuntu 10.10 driver for GeForce GT 425M GPU.

    - by Fantomas
    It came with my Sony VAIO® VPCF133FX/H 16.4" Notebook. Ubuntu does suggest an NVIDIA driver for me, but when I install it, I cannot boot back in normally. I have to boot into a failsafe mode, then reset graphics setting to default, and reboot again. Right now I am stuck in 800 x 600 mode, but I would like to do better, and take advantage of my 1GB graphics memory :(. Please let me know if you have questions.

  • whats the difference between GPU and framegrabber?

    - by user261002
    I am working on a project to monitor if human tissue has been fused with radio frequency during the surgery or not, therefore we are using a very fast camera (1800fps) and also laser illumination on the tissue and a framegrabber (1GB memory). I notice that, instead of a framegrabber, I'm able to use GPU as well, but I am not sure on what's the difference between them? Can any body explain what is the difference between a frame grabber and a GPU?

  • Chrome Open in New Tab/Window Menu Items

    - by Aequitarum Custos
    The problem is, both Firefox and Internet Explorer have "Open in New Tab" as the second option. This has become muscle memory for me by now, to the point that I don't use as often as I want to, solely because I can't open a page in a new tab without thinking about it. Is there a way to switch the position of "Open Link in new tab" and "Open link in new window", so that I can resume browsing as normal, or am I cursed by this user interface design nightmare by Google?

  • Server Hardware on the Desktop

    - by jcnnghm
    When I rebuild my desktop, I'm thinking of using server hardware instead of desktop hardware. I want to do this so I can easily add a lot of ECC memory (~20GB), and possibly more than one processor. I know that video hardware could be a problem, especially because I use 4 monitors. I should be fine with this, as long as I have two pci-e channels. Are there any downsides to doing this? Anything I'm not seeing?

  • Free alternatives to vSphere for ESXi (if one exists)

    - by Tim
    Dear All, Am feeling a touch confused and overwhemled. From what I gather even though ESXi is free I will only be able to manage my VMs (create or power on etc) for 60 days unless I buy a licence for vSphere. This is somewhat frustrating. As I am looking for a home lab to practice for various certs I was hoping to also practice using vmware stuff to do so. Have I got the wrong end of the stick? Is there a free built in web interface like there was with VMServer or is the only option vSphere (which is massively out of my price range)? Looking forward to your responses and hoping that I have just missed something obvious! Regards Tim

  • Windows Server 2003 Standard R2 CD 1 cannot boot: freeze at No Emulation

    - by TGP1994
    Hi everyone. I've been interested in the Windows Server line of OSes, so since I apply for DreamSpark, I thought I'd go download it and try it. I just so happened to have an old desktop that I was using awhile ago for Windows XP, so I imaged the drive in preparation for it to be overwritten with the new OS. (This system has an Asus A7V8X-X motherboard, an AMD Athlon XP 2800+ processor, and 1GB of RAM.) I tried burning the first disk image on my newer desktop computer, running Windows XP, although the CD burner consistently failed at a particular track area from cd to cd, so it seemed like the burner was toast there. Fortunately, I had a laptop, so I transferred the images over to that, then burned the first disc there. First time around went great, and the burning program reported no errors. I then took the CD over to the computer that I was intending to install Server onto, set the BIOS to boot from the CD drive, then I booted it up. Like normal, after the POST, it printed "Boot from ATAPI CD-Rom: No Emulation", which I was used to seeing with bootable cds. I waited for the "Press any key to continue..." message that I had become so familiar with in windows discs, although I saw none. The computer sat there for about 5 seconds with the cd spinning, then it spun down like it was done reading it. Nothing else happened. No response from the keyboard. I tried again, same result. I then downloaded IMGBurn, and I put the burned cd into the laptop that burned it originally. I also downloaded a fresh image from the dreamspark site. I ran a verify session, and everything checked out. I later tried getting various DOS startup discs, then I tried booting the winnt binary, which supposedly initiates the installation process. Either the shells reported that not enough memory was available (since they would be running in low memory mode), or FreeDOS in particular would report Illegal instructions right away. Is the image corrupt at dreamspark, or am I doing something wrong?

  • Is there a system monitoring tool that lets me write complex queries against the data?

    - by benhsu
    I am looking for a system stat collection tool that will let me write queries against the data collected. I am planning to answer questions like: what is the average load, over the last 30 days, on this machine between 9AM and 5PM, as opposed to at night what was the average disk io on these 10 machines yesterday what was the average daytime memory usage on these 10 machines last week, as opposed to 2 weeks ago Has anyone done this with, say, collectd or graphite?

  • Choosing a Linux distribution

    - by Luke Puplett
    Dangerous territory with this question so please try to be impartial and instead focus on what to look for when choosing a Linux distribution. I'm completely new to Linux. I thought it'd never happen but I need to have a Linux box to play with and I have a spare fanless Atom PC (32-bit only). I'll be using the machine as a non-commercial hobby server, the trouble is, I don't even know how to compare Linux distributions and why people pick one over another. If anything, I want to have an easy install from USB stick. My question is: what do you look for when choosing a (free?) Linux distribution for a server? If you can, please explain what sorts of things actually differ between one and another without saying which you think is better, just the facts. The way I see it, Linux as a server is just an SSH console and I find it hard to imagine what could be different between one and another.

  • lshw tells me my processor is a 64 bits but my motherboard has a 32 bits width

  • create a bootable usb to automatic repair windows xp system32 files

    - by Edo Post
    Is it possible to create a script/live distro that replaces some system32 files? To explain it a bit more in details: There is a company that has multiple computers (think in 100/1000's) and they all are missing the same system32 files since the company's software removed it. The systems are distributed all over the world and are managed by "normal" people who don't have any knowledge about computers. I want to create a usb stick that i can mail to all those people which contains a script that executes when you boot the usb. this script should replace the missing system32 files without any user input is this possible, and if so how could i manage this?

  • SQL Server Full Text Search resource consumption

    - by Sam Saffron
    When SQL Server builds a fulltext index computer resources are consumed (IO/Memory/CPU) Similarly when you perform full text searches, resources are consumed. How can I get a gauge over a 24 hour period of the exact amount of CPU and IO(reads/writes) that fulltext is responsible for, in relation to global SQL Server resource usage. Are there any perfmon counters, DMVs or profiler traces I can use to help answer this question?

  • Can't install Ubuntu 12 into VirtualBox (USB not recognized, ISO would not boot)

    - by wvxvw
    I'm trying out VirtualBox 4.18 and wanted to install Ubuntu 12 as a test. After installing VirtualBox (on Debian squeeze/sid), creating a virtual machine for Ubuntu and pointing it in Settings Storage IDE Controllers to the ISO with the proper version of Ubuntu, checked the "Live CD" option. Tried to define the IDE as master / slave, primary / secondary - all to no effect, and trying to boot this system, I'm getting to the screen which says: FATAL: could not read from the boot medium! System halted I've copied the same ISO to the USB stick, and I can boot from the USB (outside VirtualBox). I've looked at couple of tutorials / walk-through, there's nothing I can see that I would've done wrong. So, how would I configure it to boot from the desired ISO? Below is the snapshot with the current settings (sorry, I don't know how to get them as text).
