  • How to organize my site's file system properly?

    - by Wolfpack'08
    Doing some reading on Stack Overflow, I've found a lot of information suggesting that proper organization of a file system is crucial to a well-written web app. One of the key pieces of evidence is high-frequency references to "separation of concerns" in questions related to keeping programs organized. Now, I've found some information on organizing file systems (Filesystem Hierarchy Standard) from 2004. It raises only two concerns: first, the standard's a bit dated, so I believe it may be possible to do better given the changes in technology over the past 8 years; second, and most important, my application is very small compared to an entire Linux distro. I think that the file system should be organized very differently because of that. Here's what I'm looking at, currently: /scripts, /databases, /www -> /dev, /production -> login, router, admin pages, /sites -> content types, static pages /modules, /includes, /css, /media -> /module-specific-media

  • ManagementObjectSearcher error [migrated]

    - by Piotrek
    Some of our customers inform us that in some cases following error appears: System.Management.ManagementException: Blad dostawcy. at System.Management.ManagementException.ThrowWithExtendedInfo(ManagementStatus errorCode) at System.Management.ManagementObjectCollection.ManagementObjectEnumerator.MoveNext() The error is generated while trying to loop through a colection returned by Get() method of the System.Mamangment.ManagementObjectSearcher object. This is the code of my method: private bool PrinterExists(string printerName) { bool retVal = false; SelectQuery q = new SelectQuery("select caption from win32_printer"); using (ManagementObjectSearcher searcher = new ManagementObjectSearcher(q)) { foreach (ManagementObject printer in searcher.Get()) { if(printer["Caption"].ToString() == printerName) { retVal = true; break; } } } return retVal; } It seems that the problem appears only on Windows XP. The only workaround I know is reconstruction of WMI database. It sometimes helps, but unfortunatelly not always. Can anyone tell me what is the reason of this error and how can I fix it?

  • How can I enable audio system on Envy 15t-3200

    - by Dean Howell
    I just received my HP Envy 15 (June 2012 model) and I cannot get my audio system to fully function. This laptop has 6 speakers. 1.) 2 speakers on the front of the laptop (Stereo). 2.) 2 speakers above the keyboard, just before the LCD hinges. 3.) 2 Subwoofer speakers underneath the battery cover facing downward. Only the 2 speakers in the front are working. This is a "Beats" audio system. There have been many beats audio laptops before this one, so maybe if someone has experience with those, it might translate to this device.

  • Guide to installing a fully encrypted file system?

    - by Michael Stum
    I have a little Netbook on which I want to install Ubuntu 10.10 (32-Bit) on. However, since it is a portable PC I want to completely encrypt the file system (in case of theft). Currently it runs Windows 7 Starter and I use TrueCrypt which installs a custom boot loader that asks for the password. I remember from the past that Linux can do that as well by putting /boot on it's own, unencrypted partition. Since it's been ages since I last worked with file system encryption (I remember setting up LVM and a custom patched grub to ask for the password) I wonder how that would work nowadays and if there is a step-by-step how-to for it?

  • Delete U3 System from SanDisk Cruzer USB Drive [closed]

    - by Petriborg
    Possible Duplicate: How do I get rid of “U3 System” on my USB drive? SanDisk Cruzer come with a "U3" malware built into them. Its intended for windows, but on Ubuntu it shows up as a "U3 System" CD on the desktop and as /dev/scd1 -> sr1 My question - How do I permanently delete this from the device without windows? I'm aware of the windows program, but I don't have access to any, and in any event, I wouldn't want to insert the stick into a windows box because it automatically installs its malware to any windows box comes into contact with! A friend of mine realized you could delete the cdrom via sudo echo "1" > /sys/class/block/srXXX/device/delete But it will come back if you reboot.

  • Shutdown, Restart, Halt issues, not powering off system

    - by Jalomba
    Before any one says search around, I have, to no avail. I can't seem to get it working after trying every fix out there. So basically, when I turn off my laptop it shuts down fine but the last line is "System will now halt" but power never gets cut, I've tried shutdown -P and shutdown -h same result. Then when I try restart it goes through the same process but hangs on "System will now restart" But I can't figure it out, I am running full Ubuntu with no other Operating Systems. Any tips?

  • Getting "System program problem detected" pops up regularly after dist-upgrade

    - by grrrbytes
    This started to happen immediately after I had rebooted the first time after doing a system upgrade to 12.04 from 11.10. It first starts with a dialogue that says "System program problem detected". Then when I try to hit 'report problem' not much happens. I am led through a dialogue that always ends up the problem cannot be solved. I am running a MacBook1,1 I am aware this is not a lot of information, however I'm not sure which information I need to publish and how should I obtain it to debug this problem. Here's a screenshot!

This morning i upgraded to 11.04 and it also went well. i just realise some of the effects were gone. so i open compizconfig settings manager, i've tried to enable the destop cube and the expo and it prompted me of desabling somethings here and there. honestly i went fast couldn't undo what i've done and i realize the new application launcher and the system bar weren't showing properly, so i decided to restart my machine.After that 'bummer', nothing were like before.no system bar, no application launcher, not menu bar for any of my applications not even for the console. How i'm going to solve this one this time. thanks for reading this and specially for helping out.

  • Ubuntu 13.04 is showing some error while opening my computer

    - by Singh
    Few months before when I was using Ubuntu 12.04 then I found some errors while starting my computer. Due to this problem I had given my CPU to a shop to repair it I don't know what he has done to my CPU but I only know that finally I got my CPU with Ubuntu 13.04. The technician was unable to make any partition and I also think that he had installed 13.04 over 12.04 and so now my computer is showing some error when I'm starting my computer the error is as follows: error: attempt to read or write outside of the disk 'hd0'. grub rescue _ Before showing this error, few times my computer was working very slow. So kindly someone tell me that is there any way by which I can start my computer. Please also tell me that what things I have to keep in mind while using Ubuntu so that in future I find no difficulties(errors) while using Ubuntu.

  • can't update 12.04 getting package header error

    - by joel
    I originally posted this question, and was redirected to another thread where the question had already been asked. I then posted to that thread and had my post deleted by moderator fossfreedom, and told to post a "new" question... so wth ever.... I don't care if it's old or new I just need help here people! In a nutshell, I can't use sudo apt-get update or the GUI update tool to update my system. Anytime I try using either tool it gives me an error about packages missing headers. I can't send error reports, I have tried all the listed solutions from this post: I can't update my system properly, "no package header" error and from this post: "Problem with MergeList" error when trying to do an update and neither one work. I just want a working solution since I don't have the means of re-installing the OS entirely, and I REALLY don't want to have to go back to using Windows.

  • ERROR #342: DEVICE_SHADER_LINKAGE_SEMANTICNAME_NOT_FOUND

    - by Telanor
    I've stared at this for at least half an hour now and I cannot figure out what directx is complaining about. I know this error normally means you put float3 instead of a float4 or something like that, but I've checked over and over and as far as I can tell, everything matches. This is the full error message: D3D11: ERROR: ID3D11DeviceContext::DrawIndexed: Input Assembler - Vertex Shader linkage error: Signatures between stages are incompatible. The input stage requires Semantic/Index (COLOR,0) as input, but it is not provided by the output stage. [ EXECUTION ERROR #342: DEVICE_SHADER_LINKAGE_SEMANTICNAME_NOT_FOUND ] This is the vertex shader's input signature as seen in PIX: // Input signature: // // Name Index Mask Register SysValue Format Used // -------------------- ----- ------ -------- -------- ------ ------ // POSITION 0 xyz 0 NONE float xyz // NORMAL 0 xyz 1 NONE float // COLOR 0 xyzw 2 NONE float The HLSL structure looks like this: struct VertexShaderInput { float3 Position : POSITION0; float3 Normal : NORMAL0; float4 Color: COLOR0; }; The input layout, from PIX, is: The C# structure holding the data looks like this: [StructLayout(LayoutKind.Sequential)] public struct PositionColored { public static int SizeInBytes = Marshal.SizeOf(typeof(PositionColored)); public static InputElement[] InputElements = new[] { new InputElement("POSITION", 0, Format.R32G32B32_Float, 0), new InputElement("NORMAL", 0, Format.R32G32B32_Float, 0), new InputElement("COLOR", 0, Format.R32G32B32A32_Float, 0) }; Vector3 position; Vector3 normal; Vector4 color; #region Properties ... #endregion public PositionColored(Vector3 position, Vector3 normal, Vector4 color) { this.position = position; this.normal = normal; this.color = color; } public override string ToString() { StringBuilder sb = new StringBuilder(base.ToString()); sb.Append(" Position="); sb.Append(position); sb.Append(" Color="); sb.Append(Color); return sb.ToString(); } } SizeInBytes comes out to 40, which is correct (4*3 + 4*3 + 4*4 = 40). Can anyone find where the mistake is?

  • Can a Linux system crash cause network issues?

    - by Supratik
    I have a Ubuntu box in my network which crashed, all the system connected to the switch in which the Ubuntu system was connected started giving problem. I removed that system from the network, since that was the last change I made in my network and everything was fine. So, to confirm this I again connected the system back to the network and the same network outage happened. When I checked the links it was fine. When I rebooted the problematic system and again connected back to the network switch everything started working. I think possibly the crash of the Ubuntu system could have caused this outage. Is there any possibility that a kernel crash can cause network issues?

  • Getting error message when trying to start a virtual machine

    - by Sunil J
    I have been using VMWare on Windows for a long time. But after a long wait, I moved to VirtualBox on Ubuntu 11.10. I installed Ubuntu, 32 Bit, installed all available updates and installed Virtual Box. When I try to create a new Windows installation inside VirtualBox, I got the following error messages. 1st error dialogue VirtualBox - Error Failed to open a session for the virtual machine Windows XP.<br> The virtual machine '**Windows XP**' has terminated unexpectedly during startup with exit code 1.<p> Details<p> Result Code: <br> NS_ERROR_FAILURE (0x80004005)<br> Component: <br> Machine<br> Interface: <br> IMachine {5eaa9319-62fc-4b0a-843c-0cb1940f8a91}<p> 2nd error dialogue **Virtualbox - Error in suplibOsinit**<br> **Kernal driver not installed (rc--1908)**<br> Please install the virtualbox-dkmbs package and execute 'modprobe vboxdrv' as root.<p> Steps I tried I have already tried reinstalling VirtualBox.

    I am using Ubuntu Server as a SMB server at work and two days ago I have tried to upgrade it to 12.04. After reboot, I got this grub_xput missing grub rescue> and all attempts to start from this prompt failed (missing components, although grub directory is normally set as prefix). My system sits and boots on an LVM (soft raid-5). I have read almost all posts in many forums, tried grub rescue, boot-repair, ubuntu-secure-remix with boot-repair but without positive result. This is the log of my last (and best so far) attempt to fix this system. Any suggestions? Please help.

Why does this happens? how can i fix it? please help. Just to let you know i have my system up to date on 12.04 32 bits version, working on an Acer aspire AOD257, 1 Gb RAM, Intel® Atom™ CPU N570 @ 1.66GHz × 4 .
