  • Cloned partition not seen correctly by disk utility & gparted

    - by enrico
    Some days ago I cloned my /dev/sda1 partition with clonezilla in partition-to-partition mode to /dev/sda3. It worked, but now that I've finished the setup of system in /dev/sda3, I wanna reinstall /dev/sda1 for other stuffs. This partition is NOT mounted, but ubuntu's DISK UTILITY thinks it is, while it doesn't see as mounted the currently active / partition /dev/sda3. This is the df- TH output : Filesystem Type Size Used Avail Use% Mounted on /dev/sda3 ext4 32G 6.2G 24G 21% / udev devtmpfs 2.2G 13k 2.2G 1% /dev tmpfs tmpfs 845M 906k 844M 1% /run none tmpfs 5.3M 0 5.3M 0% /run/lock none tmpfs 2.2G 115k 2.2G 1% /run/shm /dev/sdb1 fuseblk 321G 147G 174G 46% /Dati Gparted instead, sees /dev/sda1 as NOT mounted (checked with Information option), but it display the BOOT flag on this partition, while the real booted partition /dev/sda3, hasn't it. If I try to format the /dev/sda1 partition, it gives me this error : GParted 0.8.1 --enable-libparted-dmraid Libparted 2.3 Format /dev/sda1 as ext2 00:00:02 ( ERROR ) calibrate /dev/sda1 00:00:00 ( SUCCESS ) path: /dev/sda1 start: 2048 end: 62500863 size: 62498816 (29.80 GiB) set partition type on /dev/sda1 00:00:02 ( SUCCESS ) new partition type: ext2 create new ext2 file system 00:00:00 ( ERROR ) mkfs.ext2 -L "" /dev/sda1 mke2fs 1.41.14 (22-Dec-2010) /dev/sda1 is mounted; will not make a filesystem here! How is possible to correct this behaviour ? Is this due to some lacking option in clonezilla phase ? TIA Enrico

  • How do I install a DVD decryption library?

    - by rocket101
    I recently built a computer running Ubuntu 11.10. It works great, except for one thing. With some video DVDs, when I insert them into my drive, the movie player just says "An error occurred. Could not read DVD. This may be because the DVD is encrypted and a DVD decryption library is not installed." My mac plays the DVD just fine. What is a DVD decryption library, and how can I install it? Thanks! EDIT: I need LEGAL way to do this. All I want is to be able to use this computer as a HTPC!

  • Why does Ubuntu only detect one USB LAN adapters at a time?

    - by EGO
    I try to connect real switch with my computer for an exam preparation, for this purpose I need more than one LAN cards, and there is only one built in LAN card in my computer. So, to get more LAN cards, I bought 4 USB Ethernet adapters (as I have 4 usb ports in may laptop 2 usb 2.0 ports, 2 usb 3.0 ports). When I plug these adapters in my computer Ubuntu only detects one LAN card from 2.0 usb ports, and one LAN card from 3.0 ports. And sometimes detects only one USB LAN from all the usb ports. Actually the real problem is Ubuntu shows these USB LAN adapters in the "lsusb", but does not list them in "ifconfig". Kontron (Industrial Computer Source / ICS Advent) is my LAN USB ethernet. abc@ubuntu:~$ lsusb Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 004 Device 001: ID 1d6b:0003 Linux Foundation 3.0 root hub Bus 001 Device 002: ID 8087:0024 Intel Corp.

Looking for some urgent help. Thanks

  • How to get faster graphics in KVM? VNC is painfully slow with Haiku OS guest, Spice won't install and SDL doesn't work

    - by Don Quixote
    I've been coming up to speed on the Haiku operating system, an Open Source clone of BeOS 5 Pro. I'm using an Apple MacBook Pro as my development machine. Apple's BootCamp BIOS does not support more than four partitions on the internal hard drive. While I can set up extended and logical partitions, doing so will prevent any of the installed operating systems from booting. To run Haiku directly on the iron, I boot it off a USB stick. Using external storage is also helpful because I am perpetually out of filesystem space. While VirtualBox is documented to allow access to physical drives, I could not actually get it to work. Also VirtualBox can only use one of the host CPU's cores. While VB guests can be configured for more than one CPU, they are only emulated. A full build of the Haiku OS takes 4.5 under VB. I had the hope of reducing build times by using KVM instead, but it's not working nearly as well as VirtualBox did. The Linux Kernel Virtual Machine is broken in all manner of fundamental ways as seen from Haiku. But I'm a coder; maybe I could contribute to fixing some of those problems. The first problem I've got is that Haiku's video in virt-manager is quite painfully slow. When I drag Haiku windows around the desktop, they lag quite far behind where my mouse is. It's quite difficult to move a window to a precise position on the screen. Just imagine that the mouse was connected to the window title bar with a really stretchy spring. Also Haiku's mouse lags quite far behind where I have moved it. I found lots of Personal Package Archives that enable Spice from QEMU / KVM at the Ubuntu Personal Package Arhives. I tried a few of the PPAs but none of them worked; with one of them, the command "add-apt-repository" crashed with a traceback. There is a Wiki page about Spice, but it says that it only works on 64-bit. My Early 2006 MacBook Pro is 32-bit. Its Apple Model Identifier is MacBookPro1,1; these use Core Duos NOT Core 2 Duos. I don't mind building a source deb for 32-bit if I can expect it to work. Is there some reason that Spice should be 64-bit only? Does it need features of the x86_64 Instruction Set Architecture that x86 does not have? When I try using SDL from virt-manager, the configuration for Local SDL Window says "Xauth: /home/mike/.Xauthority". When I try to start my guest, virt-manager emits an error. When I Googled the error message, the usual solution was to make ~/.Xauthority readible. However, .Xauthorty does not exist in my home directory. Instead I have a $XAUTHORITY environment variable. There is no way to configure SDL in virt-manager to use $XAUTHORITY instead of ~/.Xauthority. Neither does it work to copy the value of $XAUTHORITY into the file. I am ready to scream, because I've been five fscking days trying to make KVM work for Haiku development. There is a whole lot more that is broken than the slow video. All I really want to do for now is speed up my full builds of Haiku by using "jam -j2" to use both cores in my CPU. I may try Xen next, but the last time I monkeyed with Xen it was far, far more broken than I am finding KVM to be. Just for now, I would be satisfied if there were some way to use my USB stick as a drive in VirtualBox. VB does allow me to configure /dev/sdb as a drive, but it always causes a fatal error when I try to launch the guest. Thank You For Any Advice You Can Give Me. -

  • Unable to login following permission changes in device manager (11.10 + Gnome)

    - by Symanuk
    (Running Gnome 3 on Ubuntu 11.10) Everything working well (at least a couple of months), until recently when I changed the permissions through the device manager on the sda1 /2/ 3 drives, thinking it would save all the switching I seem to have to do between users in order to see / use files I previously copied across from an external drive. Now when I boot up the Ubuntu splash screen loads indefinitely, and if I go in through the GRUB / recover option, i'm getting a load of negative permission messages back (regardless of using the fsck or remount options) Either way = unusable machine (Laptop Dell Inspiron n5050), and no way through to login. I'm looking for: (1) a way back in so any help greatfully received (answers need to be pretty basic as i'm a novice), and (2) if i'm to learn anything, a decent thread on setting permissions within Ubuntu / Gnome 3. I'm new to both Ubuntu & Linux, so please be gentle!! Cheers

  • Move Joomla website to new folder

    - by Jon
    I currently have a website. I have created a new folder on the website called V2. Under this folder I have installed Joomla and configured my new looking site. I now want to make V2 the default website. I could point the website to that V2 directory however I have other folders under the current root website that I need to keep. How can I transfer V2 to the root of my website? Is it just a case of copying all the files?

  • Domain files download upon opening

    - by Marian
    I'm having this wierd issue with my Domain. My domain is saoo.eu hosted on HostZilla. The issue is that whenever I open an html/php file it automatically downloads it instead of opening it into the browser. Example the saoo.eu/test.html page. Same thing happens with the index.html file. What is going on? Also if I want an PHP code ran into an HTML file I have to add an .htaccess file. But it doesn't seem to work. Tested it before.

  • Does any CMS natively support something like aquaBrowser/Vufind

    - by nus
    What I'm looking for is to set up a CMS website with a tag cloud/search system where when you click a tag it shows as a search filter, and you get a new tag cloud which only shows tags from the articles that have the primary tag. This should let the user easily include or exclude tags from the search. Also i would like to let the user filter on publication date by using a slider... Check this for an example of how aquabrowser does this (just search for something and play with the tag cloud): http://kidscatalog.columbuslibrary.org It's not perfectly what I want and I don't want to use flash, but I like the concept alot. If something like this does not exist and i might have to code it myself, which cms is most recommended (eg easy to extend, already has tag clouds and search filters,...)

  • mssql or mysql: learning

    - by Yehuda
    I have been using MySQL for about 9 months now for websites, and i have become quite good in getting what I want out of the Database. However i am still missing most of the complicated parts. I have an excellent tutorial but it is on sql-server 2008. 1) Is it worth me switching over to mssql (I understand the SQL is different) so that I will learn all about SQL and databases in general? 2) Do most people use MySQL or MSSQL 3) What is best practice, and I am talking mainly for websites.

  • Will moving to Facebook/Disqus Commenting lighten the load on my server any?

    - by sublet
    I manage a site that gets about 50 million hits a month. It's a Wordpress site, load balanced over 6 servers, and has a varnish caching system setup. Right now, 95 - 97% of the time, page views hit the cache. The only time it serves up a new page from the server is when a new story is created, or someone is logged in looking at the stories and commenting. What I am trying to figure out is that if I move over to Facebook Comments or Disqus commenting, and get rid of the users entirely, will that lighten the load? I would think it would because the only time you would be hitting the server, and not the cache, is when you're logged in - which only the admins would be. I know it's only 2.5 - 3% but I wasn't 100% sure.

  • How to monitor outgoing server activity to detect malware?

    - by ted.strauss
    I have a website that has previously been victim of malware. I restored the site from an old backup and have made every effort to lock down the server. I have no way to be absolutely certain that the backup I used is clean, and I'm worried that this malware may re-appear. I would like to use a tool to monitor outgoing port activity to detect signs of malware activity. Unfortunately I'm using a server host that does not give me shell access, so I need to use a tool that can be installed via FTP and used via the browser. My site is Joomla :( so a Joomla extension with this capability would work, but I haven't found that yet. Any suggestions. Many thanks

  • Best Way for Developers to Upload Files to Production Server

    - by ultrajohn
    Small team of developers doing their work here and there. We have a team leader, and is sole responsible for uploading updated source files from the development server to the production server. So let's say, so if an updated files needs to be uploaded to the prod server, that concerned developer shall notify the team lead about it, and then the team lead will update the files to the prod server. So no developer has an access to the prod server except for the team lead. That's our current setup. Now, what we want to do is to give developers a way for uploading their updated files to the server without the team lead intervening in the process. What do you think is the best way to go about this?

  • How to fix Google 404 not found Crawl Errors?

    - by Freeme
    I was checking on Google webmater tool for my blog site to see if there's any indication on why my blog traffic decreased to half in one day and i saw 43 Not Found crawl errors and 5 in Sitemap Not Found errors. The 5 Not Found errors in Sitemap were the links to categories. I guess I renamed categories that's why google can't find the links. As for the 43 other Not Found errors, I see blog post titles that contains (' .) EX: McDonald's, O.N.E. They weren't found by google crawler. Blog post with /CachedYou at the end and blog posts with /www.example.com attached at the end, they weren't found by Google crawlers either. My question is how do I correct those Not Found Errors?

  • creating the nodes for path finding during run time - more like path making and more

    - by bigbadbabybear
    i'm making my 1st game. i'm using javascript as i currently want to learn to make games without needing to learn another language but this is more of a general game dev question its a 2d turn-based tile/grid game. you can check it here http://www.patinterotest.tk/ it creates a movable area when you hover a player and it implements the A* algo for moving the player. The Problem: i want to make the 'dynamic movable area creation' already implement a limited number of steps for a player. The Questions: what is a good way to do this? is there another algorithm to use for this? the A* algorithm needs a start and destination, with what i want to do i don't have a destination or should i just limit the iteration of the A* algo to the steps variable? hopefully you understand the problem & questions easily

  • XNA 4.0 2D sidescroller variable terrain heightmap for walking/collision

    - by JiminyCricket
    I've been fooling around with moving on sloped tiles in XNA and it is semi-working but not completely satisfactory. I also have been thinking that having sets of predetermined slopes might not give me terrain that looks "organic" enough. There is also the problem of having to construct several different types of tile for each slope when they're chained together (only 45 degree tiles will chain perfectly as I understand it). I had thought of somehow scanning for connected chains of sloped tiles and treating it as a new large triangle, as I was having trouble with glitching at the edges where sloped tiles connect. But, this leads back to the problem of limiting the curvature of the terrain. So...what I'd like to do now is create a simple image or texture of the terrain of a level (or section of the level) and generate a simple heightmap (of the Y's for each X) for the terrain. The player's Y position would then just be updated based on their X position. Is there a simple way of doing this (or a better way of solving this problem)? The main problem I can see with this method is the case where there are areas above the ground that can be walked on. Maybe there is a way to just map all walkable ground areas? I've been looking at this helpful bit of code: http://thirdpartyninjas.com/blog/2010/07/28/sloped-platform-collision/ but need a way to generate the actual points/vectors.

  • LWJGL in Visual Studio (possible)?

    - by Suds
    I switched from XNA and C# to LWJGL and Java about 14 months ago. Inherently, this called for a switch in IDE. I started using eclipse because I have also done some basic Android development in the past. I soon switched to Netbeans - Eclipse is just too primitive. After using netbeans for about six months, I've started looking over the fence at Visual Studio 11, toying with Metro apps for windows 8. Now I want to know, is there any known way to use Visual Studio for LWJGL?

  • Transform coordinates from 3d to 2d without matrix or built in methods

    - by Thomas
    Not to long ago i started to create a small 3D engine in javascript to combine this with an html5 canvas. One of the issues I run into is how can you transform 3d to 2d coords. Since I cannot use matrices or built in transformation methods I need another way. I've tried implementing the next explanation + pseudo code: http://freespace.virgin.net/hugo.elias/routines/3d_to_2d.htm Unfortunately no luck there. I've replace all the input variables with data from my own camera and object classes. I have the following data: An object with a rotation, position vector and an array of 4 3d coords (its just a plane) a camera with a position and rotation vector the viewport - a square 600 x 600 surface. The example uses a zoom factor which I've set as 1 Most hits on google use either matrix calculations or don't implement camera rotation. Basic transformation should be like this: screen.x = x / z * zoom screen.y = y / z * zoom Can anyone point me in the right direction or explain to me howto achieve this? edit: Thanks for all your posts, I haven't been able to apply all this to my project yet but I hope to do this soon.

  • Initializing and drawing a mesh using OpenTK

    - by Boreal
    I'm implementing a "Mesh" class to use in my OpenTK game. You pass in a vertex array and an index array, and then you can call Mesh.Draw() to draw it using a shader. I've heard VBO's and VAO's are the way to go for this approach, but nowhere have I found a guide that shows how to get Data Video Memory Shader. Can someone give me a quick rundown of how this works? EDIT: So far, I have this: struct Vertex { public Vector3 position; public Vector3 normal; public Vector3 color; public static int memSize = 9 * sizeof(float); public static byte[] memOffset = { 0, 3 * sizeof(float), 6 * sizeof(float) }; } class Mesh { private uint vbo; private uint ibo; // stores the numbers of vertices and indices private int numVertices; private int numIndices; public Mesh(int numVertices, Vertex[] vertices, int numIndices, ushort[] indices) { // set numbers this.numVertices = numVertices; this.numIndices = numIndices; // generate buffers GL.GenBuffers(1, out vbo); GL.GenBuffers(1, out ibo); GL.BindBuffer(BufferTarget.ArrayBuffer, vbo); GL.BindBuffer(BufferTarget.ElementArrayBuffer, ibo); // send data to the buffers GL.BufferData(BufferTarget.ArrayBuffer, new IntPtr(Vertex.memSize * numVertices), vertices, BufferUsageHint.StaticDraw); GL.BufferData(BufferTarget.ElementArrayBuffer, new IntPtr(sizeof(ushort) * numIndices), indices, BufferUsageHint.StaticDraw); } public void Render() { // bind buffers GL.BindBuffer(BufferTarget.ArrayBuffer, vbo); GL.BindBuffer(BufferTarget.ElementArrayBuffer, ibo); // define offsets GL.VertexPointer(3, VertexPointerType.Float, Vertex.memSize, new IntPtr(Vertex.memOffset[0])); GL.NormalPointer(NormalPointerType.Float, Vertex.memSize, new IntPtr(Vertex.memOffset[1])); GL.ColorPointer(3, ColorPointerType.Float, Vertex.memSize, new IntPtr(Vertex.memOffset[2])); // draw GL.DrawElements(BeginMode.Triangles, numIndices, DrawElementsType.UnsignedInt, (IntPtr)0); } } class Application : GameWindow { Mesh triangle; protected override void OnLoad(EventArgs e) { base.OnLoad(e); GL.ClearColor(0.1f, 0.2f, 0.5f, 0.0f); GL.Enable(EnableCap.DepthTest); GL.Enable(EnableCap.VertexArray); GL.Enable(EnableCap.NormalArray); GL.Enable(EnableCap.ColorArray); Vertex v0 = new Vertex(); v0.position = new Vector3(-1.0f, -1.0f, 4.0f); v0.normal = new Vector3(0.0f, 0.0f, -1.0f); v0.color = new Vector3(1.0f, 1.0f, 0.0f); Vertex v1 = new Vertex(); v1.position = new Vector3(1.0f, -1.0f, 4.0f); v1.normal = new Vector3(0.0f, 0.0f, -1.0f); v1.color = new Vector3(1.0f, 0.0f, 0.0f); Vertex v2 = new Vertex(); v2.position = new Vector3(0.0f, 1.0f, 4.0f); v2.normal = new Vector3(0.0f, 0.0f, -1.0f); v2.color = new Vector3(0.2f, 0.9f, 1.0f); Vertex[] va = { v0, v1, v2 }; ushort[] ia = { 0, 1, 2 }; triangle = new Mesh(3, va, 3, ia); } protected override void OnRenderFrame(FrameEventArgs e) { base.OnRenderFrame(e); GL.Clear(ClearBufferMask.ColorBufferBit | ClearBufferMask.DepthBufferBit); Matrix4 modelview = Matrix4.LookAt(Vector3.Zero, Vector3.UnitZ, Vector3.UnitY); GL.MatrixMode(MatrixMode.Modelview); GL.LoadMatrix(ref modelview); triangle.Render(); SwapBuffers(); } } It doesn't draw anything.

  • How to fix “Unable to cast COM object of type ‘Microsoft.SharePoint.Library.SPRequestInternalClass’ to interface type ‘Microsoft.SharePoint.Library.ISPRequest” using PowerGUI

    - by ybbest
    I got the error today when debugging some of my PowerShell Script in PowerGUI. The script works perfectly fine in PowerShell console. Then I had spent a couple of hours scratching my head, trying to figure out why. It turns out that the PowerShell Variables Panel causes the problem. Not quite sure why, but collapse the panel fix the problem. Problem: It throws the following exception when debugging my PowerShell Script. Analysis: It turns out that the PowerShell Variables Panel causes the problem. I assume it calls some function to grab value of some of variables which cause the problems. Solution: Collapse or Close the variables panel fix the problem

  • Binding multiple arrays for WHERE IN in PostgreSQL

    - by Alec
    So I want to prepare a query something like: SELECT id FROM users WHERE (branch, cid) IN $1; But I then need to bind a variable length list of arrays like (('a','b'),('c','d')) to it. How do I go about doing this? I've tried using ANY but can't seem to get the syntax right. Cheers, Alec Edit: After some fiddling around, this is valid syntactically: SELECT id FROM users WHERE (branch, cid) = ANY ($1::text[][]); and then binding the string '{{a,b},{c,d}}' to $1 but throws the error "operator does not exist: record = text". Changing 'text' to 'record' then throws "input of anonymous composite types is not implemented". Any ideas?

  • need .htaccess RewriteRule advise

    - by Abuda Dumiaty
    I've looked around for an answer to this, no luck. what i want to do is replace: http://localhost/mysite/admin/something with: http://localhost/mysite/admin/?p=something Here's the best formula I came up with since yesterday: RewriteEngine On RewriteBase /mysite/ RewriteRule ^(superv/)([^\?/]+)$ $1\?p=$2 [NC] Yet it's not working. Note: It think the "RewriteBase" thingy has nothing to do with the problem because this line is working like a charm: RewriteRule ^(javascripts/main\.js)$ $1\.php [NC] Any ideas? thanks in advance.
