  • Ubuntu and WiFi Network

    - by Anonymous
    I have been trying to figure out this problem. I am currently dual-booting Ubuntu with my Windows machine. My Ubuntu would connect to my wireless router but it cannot access any web pages nor ping any hosts. Wired connection works just fine. My Windows OS in the same machine (with the exact same network configuration as my Ubuntu machine) connects and works fine. I don't know why Ubuntu cannot access the Internet. Any ideas?

  • Analyzing I/O Characteristics and Sizing Storage Systems for SQL Server Database Applications

    Understanding how to analyze the characteristics of I/O patterns in the Microsoft® SQL Server® data management software and how they relate to a physical storage configuration is useful in determining deployment requirements for any given workload. A well-performing I/O subsystem is a critical component of any SQL Server application. I/O subsystems should be sized in the same manner as other hardware components such as memory and CPU. As workloads increase it is common to increase the number of CPUs and increase the amount of memory. Increasing disk resources is often necessary to achieve the right performance, even if there is already enough capacity to hold the data. Too many SQL Servers to keep up with?Download a free trial of SQL Response to monitor your SQL Servers in just one intuitive interface."The monitoringin SQL Response is excellent." Mike Towery.

  • UbuntuStudio 12.04 does not boot after install - no "intrd" image

    - by user72705
    After installing Ubuntu Studio 12.04 from DVD onto the fourth hard disk, it fails to boot, even when explicitly choosing the fourth hard disk as the boot device. I have SUSE 11.2 on the first 2 SCSI disks (which form a RAID) and Studio64 on the 1st IDE disk (that is, the third disk). Looking at the /boot directory on the Ubuntu partition, I see there is no initrd image. Editing the GRUB configuration file to include (hd3,1)/vmlinuz and of course (hd3,1)/initrd should fix the problem. But still GRUB gives a file not found error. This appears to me that, no mkintrd during the booting process (checked with LiveCD) runs like in OpenSUSE. How do I create the initrd to make Ubuntu bootable.

  • How does Ubuntu achieve RGB subpixel rendering for Mono applications?

    - by user100751
    Distributions in the *Ubuntu ecosystem support proper RGB subpixel rendering in Mono based applications (e.g. Banshee) by default, i.e. out of the box without any additional configuration requirements, whereas e.g. Fedora does not. I am aware of general patent infringement issues and the freetype-freeworld libs, but never managed to enable RGB subpixel rendering for Mono in Fedora - it keeps using greyscale. So, as the question title implies: how does *Ubuntu achieve RGB subpixel rendering in Mono applications?

  • Is it the job of a developer to suggest IT requirements?

    - by anything
    I am the only developer working on a web application which is nearing to its end. Now we are looking into making it Live in maybe a couple of months time. This is a web application for a non IT company. Though they have their own internal IT team, they have asked me on what will be the hardware requirements for the live servers eg. RAM, 32 bit or 64 bit. Shouldn't the internal IT team be doing this or since I am the only person working on the project is it my resposiblity to let them know of the any specific hardware requiremnts which may impact the performance of the project? The reason I am asking this question is that, I have not this before. All the times I used to be given a server and asked to deploy apps on it. I never used to worry about the server configuration etc.

  • How can I convince a project manager that there is no way to solve all the compatibility issues?

    - by SAFAD
    I have been working on this project for more than a year now, and we are close to release, the project manager wants the product to be perfect and working in every single aspect. I like that and I love working under the perfection idea, but it seems he is delaying the launch too much because of compatibility issues, he wants the product to work in every single installation, every single configuration possible, and in most cases, the product just works without issues when it's on the hands of the client. UPDATE : yes the product doesn't work properly when there are conflicts, for example, other products that don't use guidelines nor standards to load libraries (causes double library load which leads to failure), cache is another example and so on..... but we warn the clients about the conflict before purchasing and help them fixing it after purchasing I've tried to explain it by giving some examples on major products, he understands the situation, but can not believe that it is near impossible (if it is not impossible) to do what he wants. Hope it is clarified enough for the community to answer.

  • Get and install Nvidia GeForce 8400 GS driver

    - by williepabon
    Recently, I changed my OS kernel from 10.04 to 11.10 (bugs), but after doing it, the video driver for the 8400 GS disappeared (was there in 10.04). I worked out the same procedure I did to install it in 10.04, mainly, sudo apt-get --purge remove nvidia-current sudo apt-get --purge autoremove sudo add-apt-repository ppa:ubuntu-x-swat/x-updates sudo apt-get update sudo apt-get -y install nvidia-current but it didn't work even though the commands seemed to install the driver without problems. Right now my machine is working with the standard drivers, as shown. williepabon@WP-WrkStation:~$ sudo lshw -C display [sudo] password for williepabon: *-display description: VGA compatible controller product: nVidia Corporation vendor: nVidia Corporation physical id: 0 bus info: pci@0000:05:00.0 version: a2 width: 64 bits clock: 33MHz capabilities: pm msi pciexpress bus_master cap_list rom configuration: driver=nouveau latency=0 resources: irq:16 memory:de000000-deffffff memory:c0000000-cfffffff memory:d0000000-d1ffffff ioport:cc80(size=128) memory:dfc00000-dfc7ffff Any suggestions to correct the problem?

  • Created Custom Report in Google Analytics, Primary Account Doesn't See It?

    - by Anagio
    A client shared access with me to their Google Analytics account. I created a custom report which shows up under Custom Reporting for me. I assumed they would also see this report since it was in their account but they sent me a screen shot showing there's no custom report listed. I have already sent them the shortcut link to the custom report configuration. This seems to be the way to share custom reports along with dashboards in GA now. Do custom reports only appear to the accounts (email) that created them? I would think everyone who had access to the account would see the custom report.

  • How do I fix the paths of my website?

    - by EASI
    I have Joomla 2.5.7 in my client's server updated recently from 1.6 to 1.7. I did not make that site but I am responsible for it now. I prefer to make a site from zero. Now users area clicking on the menu options and when joomla send them to a meta-url like http://iap.pa.gov.br/acervo they get the message 404 The requested URL /acervo was not found on this server. Would that be because they moved joomla folder from the root to root/iap (name of the site)? If it is, what is the configuration to adapt to that new folder?

  • What to do about unreadable grub screen

    - by stevecoh1
    I have been upgrading my Ubuntu, from 10.04 to 12.04 to 12.10 to 13.04 in the past few days with varying degrees of success. One problem that has been constant through every step of the upgrade, since 12.04 is that a portion of the text on the grub screen is off the screen to the left so I can't completely make out what the options are. As I am having other troubles with the upgrade I would like to at least be able to see what options there are to me at boot time. Is there some sort of grub configuration that can handle this?

However, I can hear audio,and the pavucontrol Play tab shows the name of the application(any media player vlc,mplayer etc.) which is running and volume control for right and left channels (FROM LEFT & FROM RIGHT Volume slider) I guess there may be a change in the system configuration/setting? How to reset it? I have reinstalled Pulseaudio, but the problem remains. I am using ubuntu 12.04 with default pulse audio.

  • How to choose a good namespace name? [Linguistically]

    - by Kees C. Bakker
    English in not my native language, therefore it is a little more difficult to pick a good name for a namespace. One example to make you see my problem a bit better: We have a set of classes that have to do with the way a company is organized (we can create organizational charts with it). Currently the namespace is CFW.CoreSystem.Organizational. Is this a good name? What is linguistically the best way to name a namespace? (CFW.CoreSystem.Configuration is better than CFW.CoreSystem.Configurables). [Moved it from StackOverflow]

  • My laptop does not have sound and the video reproduces it very rapidly. ubuntu 12.04

    - by user48221
    Once my laptop was fallen and the wi-fi broke, lead her to repairing and when they returned me already it had wi-fi again, but I realized that it did not have sound. In sound configuration it could not raise him, to know if it was a problem of the horns I connected a few headphones and neither it was listened. Because of it I knew that it was a problem of the software, and another problem that I saw, it was that the video player was going too rapidly as if it was advancing him. Where it leads her to arranging they say that they did not touch anything of software, alone they repaired the device of the wi-fi. How I can fix it?

  • Ubuntu VM cannot start after Kernel upgrade

    - by AAz
    Several Ubuntu 10.04 VMs were restarted after few months and began getting "Kernel Panic - not syncing: VFS: Unable to mount root fs on unknown-block(0,0)" message. Restoring those VMs from backup (to the "paused" state) allows to boot normally. However restarting the VM again results in the mentioned error message. I suspect it's the updated kernel version (2.6.32-37-server, 2.6.32-38-server) that misbehave - another Ubuntu VM (that's used as template for those failing VMs) still has 2.6.32-24-server and reboots fine. We're using HyperV (2008R2) as the server host. Nothing were changed in it's configuration. Has anyone faced this issue, please advise the solution. Many Thanks in advance!

  • How do I secure a Tomcat installation?

    - by spangeman
    I have installed tomcat on my Ubuntu Home 11.10 system and can successfully access the test page online after port forwarding on 8080 within my router. I have not made any other changes to the router, Ubuntu or the tomcat install, everything else has remained standard. I intend on using this to play around with Java Servlets and basic web development for my own personal use. What steps, if any, would you suggest I take to ensure this is secure? Should I change anything within the Tomcat configuration? This seemed like a good idea to limit access - http://www.seankilleen.com/2010/09/how-to-allow-only-specific-ip-addresses_30.html But I am open to any other recommendations.

  • Missing error handling in Streaming-AJAX-Proxy Log

    - by Michael Freidgeim
    We are using AjaxProxy(FROM http://www.codeproject.com/KB/ajax/ajaxproxy.aspx) on our web site, but started to notice errors accessing log.txt file. I found that the file is created by Log class and doesn't have ability to switch it off and error handling. I've added reading file name from configuration and try/catch block   public static class Log     {         private static StreamWriter logStream;         private static object lockObject = new object ();     public static void WriteLine(string msg)         {                       string logFileName = ConfigurationExtensions.GetAppSetting("AjaxStreamingProxy.LogFile" ,"");                       if (logFileName.IsNullOrEmpty())                             return;                       try                      {                             if (logStream == null )                            {                                    lock (lockObject)                                   {                                           if (logStream == null )                                          {                            logStream = File.AppendText(Path .Combine(AppDomain.CurrentDomain.BaseDirectory, logFileName));                                          }                                   }                            }                            logStream.WriteLine(msg);                      }                       catch (Exception exc)                      {                             string ignoredMsg = String .Format("The error occured while logging {0}, but processing will continue.\n {1} ", exc);                             LoggerHelper.LogEvent(ignoredMsg, MyCategorySource, TraceEventType .Warning, true);                      }         }

  • Is there a way to mirror directory changes in Terminator?

    - by Kasisnu
    I'm on Ubuntu 12.04 and am using Terminator as my primary terminal. I like it because it lets me keep a python interpreter and bash terminal open at the same time, in the same view. What is annoying is that I end up moving between directories A LOT, and then I have to do it twice. Is there a way to set up a terminator configuration to do that? To have terminator mirror directory changes. I'm guessing I'm not the only one that finds that frustrating!

  • Unity 3D in 11.10 with VirtualBox in OS X?

    - by Roshambo
    I'm having a horrible time with Unity 3D in Ubuntu 11.10 running in a VirtualBox VM in OS X. Such a hard time, in fact, that I'm about to give up and conclude that it simply isn't possible to use Ubuntu 3D in a configuration like this. The problem with is that windows simply do not render. I've found that killing Nautilus makes the problem go away, but that's really not much of a solution. I have installed the guest additions and am running the VM with 2048 MB RAM, 128 MB video memory, and have enabled 3D acceleration. I've tried all this on several Macintoshes, with no luck. Unity 2D, on the other hand, works fine across the board. Any advice or experience would be greatly appreciated.

  • Compiz plugin (Grid) does not update in CCSM

    - by pileofrocks
    I upgraded to 13.10. Compiz itself has been updated properly to 0.9.10.2, but in CCSM, one* plugin (Grid) shows up as the old version. I know it has been changed and I can actually see the updated version when I log in with another user. This hints of some kind of a problem with per-user settings? (* Actually I'd expect this to involve other if not all other plugins too, but I have simply not yet noticed others.) So far I have tried: resetting Compiz settings to defaults (GUI-way) does not help completely removing & reinstalling compizconfig-settings-manager and compiz-plugins packages does not help In 13.04, I had a patched/old version of the plugin, but I doubt it is about that since everything is fine with the other user (that user account existed already in 13.04). What configuration files I should try deleting?

  • Are there any resources for motion-planning puzzle design?

    - by Salano Software
    Some background: I'm poking at a set of puzzles along the lines of Rush Hour/Sokoban/etc; for want of a better description, call them 'motion planning' puzzles - the player has to figure out the correct sequence of moves to achieve a particular configuration. (It's the sort of puzzle that's generically PSPACE-complete if that actually helps anyone's mental image). While I have a few straightforward 'building blocks' that I can use for puzzle crafting and I have a few basic examples put together, I'm trying to figure out how to avoid too much sameness over a large swath of these kinds of puzzles, and I'm also trying to figure out how to make puzzles that have more of a feel of logical solution than trial-and-error. Does anyone know of good resources out there for designing instances of this sort of puzzle once the core puzzle rules are in place? Most of what I've found on puzzle design only covers creating the puzzle rules, not building interesting puzzles out of a set of rules.

  • Looking for best approach to create new projects for enviroment specifics files

    - by Ness
    ClearCase Question... Overview of requirements: There are 3 diff environments (DEV, TEST and PROD) which have a folder called 'common' that users across all envs. There are multiple servers in those 3 envs and we want to store their server environment specific configuration files in Clearcase. The executables files are different for each environment. Thus there will not be cross delivery require between dev/test/prod. Any thoughts on how we can approach this? Is keeping it simplest is the best approach here? One component to one vobs as (DEV_Serv1, TEST_Serv1, PROD_Serv1, Dev_Serv2, Test_Serv2 and etc)? OR Have multiple components VOB? One other thing is developers here like to use snapshots views.

  • When I boot it says "No any drive found" and turns off after upgrade from 9.10 to 10.04

    - by user797582
    I did an upgrade on the weekend from Ubuntu 9.10 to 10.04 (karmic to lucid). Now, when I restart my computer, it goes through the regular load screen showing my P5K Asus motherboard, just like before but instead of showing the Ubuntu load screen, it tries to start grub but fails and then says "No any drive found" and the screen goes black. I've tried changing the drive configuration in the BIOS to AHCI or RAID and that didn't work. I've tried disabling JMICRON but to no avail. I'm running out of options here. Any advice?
