• Redirect from https://mydomain.com to http://mydomain.com

  - by Charlie

  Many of my visitors have bookmarked my site already wtih https://mydomain.com. Under the bad advice of a programmer, I put my whole Joomla site under ssl. I do not sell anything or provide any member services. I asked him many times if it would slow my site down - he said it wouldn't. I knew it did, I've researched on this site and realized it does slow the site down because of no cache of the pages. Understood. Please, someone tell me how to get away from it now. I'm not sure how to approach this, should I add something to my htaccess or my main index.php file? I've looked all over the net, there is much advice for adding redirectives for going from http to https, but very few answers regarding the opposite of going from https to http. Thank you very much for your time. I appreciate it.

• apt changelog for to-be installed packages

  - by ithkuil

  GUI update-manager is able to show the "changelog" of packages to-be installed (not downloaded yet). I also found out how to provide the .changelog files in the right place for update-manager to show them, and now I'm happy since I'm able to tell my clients that they can see changelogs of my custom packages directly from their gui. Unfortunately I'm not able to find any command line tool to do the same thing and that would be more useful on servers. From what I saw it seems that this convention (putting .changelog files directly alongside the .deb files in the apt repo) is a ubuntu specific extension. There are some debian resources (the reprepro man page for example) which point on a different way to store changelogs online, http://packages.debian.org/changelogs Does anybody know if there already exists a tool like apt-cache to show the changelogs from packages which are not yet installed (nor downloaded) ?

• apt-get update bzip2 errors

  I installed Ubuntu 11.10 today on my Lenovo w500. After that when i tried running sudo apt-get update This is the error i am getting.

You can use the -tvv option to test integrity of such files. You can use the `bzip2recover' program to attempt to recover data from undamaged sections of corrupted files. I found the following similar question : Errors while updating Ubuntu 11.10 , But the solutions mentioned ( changing the download server, running apt-get clean, apt-get autoclean) and have also tried removing the /var/cache/apt/archives/lists direcotry. As a result of this, I am unable to install any new packages.

• How do I make Powertop changes permanent?

  - by arno

  I'm on a Compaq 615 and it's fan is loud as hell. Not much you can do about that but I'm trying to keep the CPU/GPU as cool as possible. This is what Powertop has to say: If I change all of them to "good", the changes don't survive a reboot. Also, upon exiting Powertop I get this: Loaded 8 prior measurements Cannot load from file /var/cache/powertop/saved_parameters.powertop Leaving PowerTOP I added the line to the "grub"-file as suggested here Upon closing gedit I get this: (gedit:2728): Gtk-WARNING **: Attempting to store changes into `/root/.local/share/recently-used.xbel', but failed: Datei »/root/.local/share/recently-used.xbel.9CIMAW« konnte nicht angelegt werden: Datei oder Verzeichnis nicht gefunden The part in German says: Couldn't be created: File or directory not found.

• Share on Facebook does not show thumbnail images

  - by matt_tm

  I have a PHP application which has a "Share on Facebook" button that, On the development server shows the thumbnail images correctly and allows the user to select between them On the live server, it does NOT show the thumbnail images at all. The relevant portion of the .htaccess file is: # Set up caching on media files for 2 days <FilesMatch "\.(gif|jpg|jpeg|png|flv)$"> ExpiresDefault A172800 Header append Cache-Control "public" </FilesMatch> I'm using the exact same set of php files and .htaccess, but the server configuration is different. What could be causing this? Note that the text appears fine. Edit1 We are also doing some URL rewriting related to images in the .htaccess (on both servers): ... RewriteRule ^.*/content/image/(.*)$ content/image/$1 [L] ... RewriteRule ^.*/images/(.*)$ images/$1 [L] ... Would that be somehow making a difference? Images appear fine all throughout the site. (I posted this question earlier as http://stackoverflow.com/questions/4142597/share-on-facebook-does-not-show-thumbnail-images) )

• Looking for literature about graphics pipeline optimization

  - by zacharmarz

  I am looking for some books, articles or tutorials about graphics architecture and graphics pipeline optimizations. It shouldn't be too old (2008 or newer) - the newer, the better. I have found something in [Optimising the Graphics Pipeline, NVIDIA, Koji Ashida] - too old, [Real-time rendering, Akenine Moller], [OpenGL Bindless Extensions, NVIDIA, Jeff Bolz], [Efficient multifragment effects on graphics processing units, Louis Frederic Bavoil] and some internet discussions. But there is not too much information and I want to read more. It should contain something about application, driver, memory and shader units communication and data transfers. About vertices and attributes. Also pre and post T&L cache (if they still exist in nowadays architectures) etc. I don't need anything about textures, frame buffers and rasterization. It can also be about OpenGL (not about DirecX) and optimizing extensions (not old extensions like VBOs, but newer like vertex_buffer_unified_memory).

• Does an onboard video affect the X windows configuration?

  - by Timothy

  Does the onboard video on the motherboard affect the X windows configuration? My system has onboard and pcie video. The onboard video is a NVIDIA GeForce 7025 GPU, On Board Graphic Max. Memory Share Up to 512MB(Under OS By Turbo Cache). I have a pcie dual head video card installed with two monitors. The video card is a GeForce 8400 GS, with 512mb memory. When installing Ubuntu 12.04, only one monitor worked. When pulling up system settings- Displays it shows a laptop. This is a desktop pc. I did get both monitors to work using nvidia using twinview -- A complicated process! When checking nvidia now it shows the monitors disabled. The Nvidia X server setting does show the GPU and all the information. I was thinking it's seeing the onboard video on the motherboard. Why else would it show laptop?

• Swap and hibernation

  - by maaartinus

  I saw a lot of recommendations claiming that for hibernation the swap partition/file must be at least as large as the main memory. This makes no sense to me. Lets assume I have 8 GB of main memory and 8 GB swap area and want to hibernate: case 1: I'm using 4 GB of virtual memory - 8 GB of swap is unnecessarily large. case 2: I'm using 8 GB of virtual memory - 8 GB of swap is just right. case 3: I'm using 12 GB of virtual memory - 8 GB of swap is too small. The outcome is: A swap area of size equal to the memory size is sufficient for hibernate IFF it doesn't get used for swapping at all. So what is the reason behind the claim that you need at least as much swap area as main memory for hibernate to work? I know that virtual memory gets used for caching too, and that the cache may be simply discarded, but what happens to hibernation if a program allocates 12 GB of virtual memory (given the above memory and swap sizes)?

• How do I install the btrfs-restore utility on 12.04?

  - by MountainX

  I would like to install btrfs-restore on Kubuntu 12.04 apt-cache search btrfs-restore returns nothing. Google "ubuntu download OR install btrfs-restore" returns nothing useful. Also, where do I get btrfs help? I'm not getting any replies on #btrfs on freenode.net. (Correction: I was too impatient. #btrfs was very helpful!) UPDATE: the previously accepted answer no longer works, so I unselected it as the answer. The PPA dmitrij.ledkov/ppa is missing now. Thanks to Pkunk at #btrfs, I posted a new solution below.

• External USB 3 drive not recognized

  - by ilan123

  Ubuntu 12.10 64 bit seems not to recognize my external hard disk. It is a Vantec NST-310S3 external disk enclosure with a WD 3TB drive. The disk has two NTFS partitions. My PC is a dual boot system. Under Windows 7 the hard disk works fine but I can't make it work with Ubuntu. When the drive is connected to the PC then the command sudo fdisk -l seems to hang forever. Below are the output of lsusb and cat /proc/partitions without the external drive and then with it connected. I added also the last lines of the dmesg command at the end.

• Create speed baseline for local web file

  - by Michael Jasper

  Is there any tool or method that will load a localhost page a number of times, and return the averaged data for load times, onload events, Dom ready events, etc? I'd like to work on page speed optimization, but need a baseline before I begin. I have used both Google analytics and Webmaster tools, but I'd like an automated solutions that runs locally. My ideal solution would be a program or script that would take the path/file, number of iterations, and then take several minutes to load the page n times without cache and crunch numbers to create a baseline.

• How to stop gecko-mediaplayer from buffering endlessly?

  - by mario

  I'm using the gecko-mediaplayer plugin (formerly "mplayerplug-in"). The totem plugin was not always working correctly with Opera, and I'm actually depending on the [Copy URL] feature of gecko-mediaplayer. However that plugin does some inept buffering of videos. It seems to default to 20% caching regardless of what you set in the preferences window. This is quite annoying for big video files. But appearantly it's by design http://groups.google.com/group/gecko-mediaplayer/browse_thread/thread/b7f0f5a3cedc8979 The Gentoo forums listed some workaround http://forums.gentoo.org/viewtopic-t-816690.html - but ~/.config/gecko-mediaplayer/gecko-mediaplayer.conf is not working in the Ubuntu version.

• Local Entities with NHibernate

  - by Ricardo Peres

  You may know that Entity Framework Code First has a nice property called Local which lets you iterate through all the entities loaded by the current context (first level cache). This comes handy at times, so I decided to check if it would be difficult to have it on NHibernate. It turned out it is not, so here it is! Another nice addition to an NHibernate toolbox! public static class SessionExtensions { public static IEnumerable<T> Local<T>(this ISession session) { ISessionImplementor impl = session.GetSessionImplementation(); IPersistenceContext pc = impl.PersistenceContext; foreach (Object key in pc.EntityEntries.Keys) { if (key is T) { yield return ((T) key); } } } } //simple usage IEnumerable<Post> localPosts = session.Local<Post>(); SyntaxHighlighter.config.clipboardSwf = 'http://alexgorbatchev.com/pub/sh/2.0.320/scripts/clipboard.swf'; SyntaxHighlighter.brushes.CSharp.aliases = ['c#', 'c-sharp', 'csharp']; SyntaxHighlighter.all();

• Do Not Track Plus Stops Web Sites from Tracking You

  - by Jason Fitzpatrick

  Do Not Track Plus is a Firefox extension that combines the do-non’t-track header with protection lists for comprehensive tracking avoidance while surfing the web. Unlike all-or-nothing no tracking flags, the Do Not Track Plus extension for Firefox allows you to set white and black lists for websites you would prefer to be tracked or not tracked by. You may, for example, want a shopping site you get benefits from or a news site that gives you customized articles to be allowed to track you. The tool also preserves anti-tracking cookies even when you wipe the rest of the cookies in your browser’s cache; effectively stopping you from accidentally rescinding your opt out cookies from anti-tracking sites.

  - by Yadnesh

  I'm currently runing Ubuntu 9.04 Jaunty. I want to upgrade to 10.04.02, but whenever I use the Update manager to do this, it fails with the error "An upgrade from 'jaunty' to 'lucid' is not supported with this tool". I also tried to run sudo do-release-upgrade -d, but it fails with the same error message: Checking for a new ubuntu release Done Upgrade tool signature Done Upgrade tool Done downloading extracting 'lucid.tar.gz' authenticate 'lucid.tar.gz' against 'lucid.tar.gz.gpg' tar: Removing leading `/' from member names Reading cache Checking package manager Can not upgrade An upgrade from 'jaunty' to 'lucid' is not supported with this tool.
