• How to resolve ambiguous key sequence?

  - by Rob Mosher

  Using BasKet, I get the following message: Ambiguous Shortcut Detected The key sequence 'Ctrl+1' is ambiguous. Use 'Configure Shortcuts' from the 'Settings' menu to solve the ambiguity. No action will be triggered. 'Ctrl+1' is shown next to 'To-Do' under the 'Tags' menu. If I look in 'Configure Shortcuts' I don't find Ctrl+1 assigned to anything (the tag shortcuts aren't listed at all, leading me to believe their assignment is hard coded). I looked under 'System Preferences Keyboard Shortcuts' and also searched through CompizConfig, but didn't find anything there that might conflict. How do I resolve this keyboard shortcut issue? I'm guessing the particular program or key sequence isn't too important. It looks like it happens with a number of KDE programs (sadly I haven't seen a solution).

• How to eliminate an old Ubuntu partition?

  - by GUI Junkie

  I installed Ubuntu 12.04 64-bit side by side with my previous 11.10 32-bit. As everything is working correctly, I want to eliminate the old partition. According to update-grub: Found Ubuntu 11.10 (11.10) on /dev/sda1 But according to GParted, /dev/sda1 is the boot partition! So, how can I discover which partition should be the boot partition for 12.04? Can I safely eliminate the /dev/sda1? Also, GParted gives /dev/sda5 as file system unknown, it's 2.93Gib and might be the swap partition (just guessing).

• Vista missing from grub bootlist after installing ubuntu

  - by tacomensa

  I installed Ubuntu on a logical partition a while ago. When I get to the grub bootlist, Vista is not there. What i get is this: Ubuntu, with linux 2.6.32-26 Ubuntu, with linux 2.6.32-26 (Recovery mode) Ubuntu, with linux 2.6.32-25 Ubuntu, with linux 2.6.32-26 (Recovery mode) Ubuntu, with linux 2.6.32-24 Ubuntu, with linux 2.6.32-26 (Recovery mode) Memory test (memtest86+) Windows vista (loader) (on/dev/sda1) windows recovery environment (loader) (on/dev/sda2) "Windows vista (loader)" is an acer erecovery manager Im guessing that grub installed on my primary partition so it overwrite the vista MBR and i dont have the option to boot vista. Is there some way i can just edit the MBR and add vista to it or how will i have to repair this? here is my boot script http://pastebin.com/7HZFjBT7

• How to fix indicator icons from being cut off?

  - by Jay

  A friend of mine just upgraded from 9.10 to 10.04 and the icons for the indicator applets all appear cut off on both the bottom and the top. See picture above. Note that the icons in the old systray/notification area on my friend's panel all still display correctly, so it's a problem with indicator clearly. My question: How can this be fixed? (I have a 10.04 system that I did a fresh install on, and I don't have this issue, so I'm guessing it's an issue with upgrading. Thanks.

• Laptop suspend appears broken, what must I roll back?

  - by M. Tibbits

  Question: What package contains the subprogram responsible for the KMenu option "sleep"? Background: I've been running KUbuntu 10.04.1 and I am completely updated. Recently (within the past month), the "sleep" menu item has stopped working. It just sits there waiting like I clicked nothing. I've check all of the logs in /var/log and nothing is added when I click sleep. I'm guessing that something I updated has bollux'ed things up, but I don't know which package contains the component that I need to roll back. In the meantime, I've installed uswsusp, but s2ram & s2both don't ask my password when the laptop resumes -- which really bothers me. So now that I've got a little time to track this down, I had to post -- any ideas??

• Apache FilesMatch regexp: Can it match by the cache buster 10 digit (rails generated) following the filename?

  - by ynkr

  According to the apache FilesMatch docs: The FilesMatch directive provides for access control by filename Basically, I only want to set an expires header for resources that have a 10 digit "cache buster" id appended to the name. So, here is my attempt at such a thing in my httpd.conf <FilesMatch "(jpg|jpeg|png|gif|js|css)\?\d{10}$"> ExpiresActive On ExpiresDefault "now plus 5 minutes" </FilesMatch> And here is an example of a resource I want to match: http://localhost:3000/images/of/elvis/eating-a-bacon-sandwich.png?1306277384 Now obviously my FilesMatch regexp is not matching so I am guessing 1 of 2 things is happening. Either my regexp is wonky or the '?1231231231' cache busting part of the file is not part of what apache considers part of the filename. Can anybody confirm and/or give me a way to cache only those resources that will not persist beyond the next deploy?

• ssh login information

  - by bob

  As the admin of my machine, I want users to be able to log into my computer with ssh, but I'm looking for a graphical way to be notified that a user is connected at the moment. If multiple users are connected, I want a list of connected users, their location, name, etc. This could be in the form of a forceCommand and 'alert' command when someone logs in, plus a icon saying how many people are connected right now in the notification bar, with the option to click on it to have more information about these users. Is there such a tool available in ubuntu, and if not, how to do it (I'm guessing it's not that difficult and could be done with under ten bash command lines) ?

• Why does this exported cube have too many vertices?

  - by Joewsh

  I'm trying to export md5mesh models. Just as a test I decided to export a simple cube (i.e. with 8 vertices). When I opened the .md5mesh file it lists the following: numverts 24 numtris 12 numweights 24 Obviously the number of triangles makes sense: 6 faces * 2 to triangulate = 12. The model only has one bone so again it even makes sense that there is one weight for each vertex. The question is though, why is the file listing 24 vertices? Is the problem the exporter or is this normal for md5mesh's? Is it something that you have to rectify when you come to parsing the file in engine? I don't want to be parsing or drawing duplicated vertices without reason. I'm guessing it's something to do with shading and normals. Is it a case of listing each vert 3 times, one for each facing normal?

• Jumping around to work on different features when you get stuck, is it a source of project failures?

  - by codecompleting

  On personal projects (or work), if one gets stuck on a problem, or waiting to figure out a solution to the problem, if you jump to another section of your code, don't you think it will be a good reason your application will be buggy or worse yet never get completed? Assuming you are not using git and code each feature to a specific branch, things can get out of hand since you have 3 different features you are working on, and you have unresolved issues in each. So when you get done to work, you get stressed out because you have these hanging issues and half-baked code lingering about. What's the best way to avoid this problem? (if you have it) I'm guessing using something like git and creating a branch per feature is the safest way to avoid this bad habit. Any other suggestions?

• Are there advantages of using hard coded URLs for localization?

  - by nbolton

  On the Synergy website, localization is detected (and can be overridden) but uses the same URL for all languages. Some websites however, like Wikipedia have language specific subdomains. What are the advantages of having either subdomains or subdirectories (i.e. a specific URL) for each language localization? Also, should it automatically redirect the user to the specific subdomain/subdir based on the language that the browser requests? I suspect that there are advantages, which I'm guessing are: When the website appears in search results for non-English languages, the translated page description will be shown (assuming there is a translation provided by the website). When a user shares a page (e.g. through twitter), it will show in a specific language. Perhaps this is a disadvantage though? Am I correct, if so, are there more advantages?

• World orientation in OpenGLES clarification

  - by Dev2rights

  I have a 3d tile map made up of individual billboards in OpenGLES. Each is a 2 triangles mesh and has a 3D Vector to determine its position and another defining its rotation from the origin at (0,0,0). Im trying to work out how to rotate the entire tile map around a point be that the origin or some arbitrary point in space. Im guessing i need to set up a Model Matrix instead for each tile. Then set up a world matrix for the world. Then on updating i would translate the world matrix and change the orientation and multiply it with each model matrix before rendering. Is this correct ?

• 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!

• Not sure which Ubuntu to install (64 or 32 bit)

  - by user285993

  I want to use Ubuntu. I have Win 7 Home Premium 32-bit right now... I used to have 64 on this laptop (Toshiba Satellite c650) but my disc got a ring of death. Intel Penium CPU B940 2.00GHz, 4GB RAM Also, I'm guessing I need an image mounter such as PowerISO to install Ubuntu, if I don't have a DVD lying around that I can mount to? I'm a noob. Thanks for your help, in advance. EDIT: My question wasn't clear... can my processor and RAM handle 64-bit Ubuntu? Hell of a lot nicer than Win7

• How can I play different sounds each time I startup?

  - by user82171

  I have read questions on Changing startup sound in Ubuntu and Changing startup music in Ubuntu. I understand how to rename 'desktop-login.ogg' and copy the sound I want as 'desktop-login.ogg'. My question is - is there a way I can play different sounds each time I login? It may sound silly, but if possible I would like to play different sounds. I am guessing that this may be perhaps possible by running some kind of script which replaces/renames the desktop-login.ogg file each time I shutdown, so that a new file is ready to be played on the next startup. But I don't know how to copy a new file from a particular folder to desktop-login.ogg upon each shutdown, nor do I know where the script should reside. I would appreciate it if someone could tell me how to do it, or if there is an easier way of doing this. Thank you

• Why have column borders gone missing in Rhythmbox gui?

  - by amadis

  My theme doesn't use shading, only borders/outlines. Since a few weeks ago Rhythmbox has stopped drawing all borders so that I can't see columns or sections very well. Even my scrollbars are not being drawn correctly. This makes the gui really hard to use. When I change themes it seems that Rhythmbox has changed its gui to use only shading to delineate sections, tabs, columns, etc.. Rhythmbox seems to be the only program that has this problem so I'm guessing this is a Rhythmbox thing, but not sure. My theme is not updated for gtk 3.6 Maybe that is the issue? Anyone know what's going on?

• Garbled screen after sleep/suspend with nVidia 8800M GTS Ubuntu 11.10

  - by user34062

  Just did a clean install of 11.10, have been using it (and enjoying it!) for about a day now. But it seems that every time I resume from a sleep or blank screen after idling for a while, my desktop, as well as any programs on the screen get "garbled" I had a few windows open and all displayed the same gui glitching except for Chromium (I am guessing because it was minimized to the Unity Launcher, and not currently on the screen when I woke the PC up.) Anyone know what might be causing this, and how I might be able to fix it? I am using a Gateway P-6860FX with a C2D 1.8GHz, and nVidia 8800M GTS 512mb. Screenshot: http://dl.dropbox.com/u/28188839/Screenshot%20at%202011-11-15%2018%3A53%3A25.png NOTE: Yes, I know I misspelled Lothlorien.... .<

• How to solve programming problems using logic? [closed]

  - by md nth

  I know these principles: Define the constrains and operations,eg constrains are the rules that you cant pass and what you want determined by the end goal, operations are actions you can do, "choices" . Buy some time by solving easy and solvable piece. Halving the difficulty by dividing the project into small goals and blocks. The more blocks you create the more hinges you have. Analogies which means : using other code blocks, yours or from other programmers . which has problem similar to the current problem. Experiments not guessing by writing "predicted end" code, in other word creating a hypothesis, about what will happen if you do this or that. Use your tools first, don't begin with a unknown code first. By making small goals you ll not get frustrated. Start from smallest problem. Are there other principles?

• Cloud 9 and Grunt.js

  - by Michael Ryan Soileau

  I'm running grunt.js on Cloud9. Most everything is working correctly, except when I try to set this option: 'watch: { options: {livereload:true},' If I add that, the terminal states: 'Fatal error: listen EACCES' I'm guessing I need to use the sudo command to run that and since c9 doesn't let you run sudo, the command fails. But why is livereload a feature that requires permission? And is there any way around it?

• Sending a Tuple object over WCF?

  - by Donut

  Is the System.Tuple class supported by WCF's Data Contract Serializer (i.e., can I pass Tuple objects to WCF calls and/or receive them as part or all of the result)? I found this page, but not the clear, definitive "you can send and receive Tuples with WCF" answer I was hoping for. I'm guessing that you can, as long as all of the types within the Tuple itself are supported by the Data Contract Serializer -- can anyone provide me with a more definitive answer? Thanks.

• BlackBerry barcode scanning library?

  - by Mat Nadrofsky

  Anyone got a good handle on a barcode scanning library that can be used to read in UPC-A, EAN-13 or other major barcode formats based on input from the digital camera? Does RIM have a standard library already available for this? I know that BlackBerry Messenger has 2D barcode scanning built-in so I'm guessing there must be something available, though not sure if it's proprietary or not.

• Import .pem public and private keys to JKS keystore

  - by Rolf

  Hi, I have public and private keys in separate .pem files that I would need to get into a JKS keystore somehow. Tried using the -import command in KeyTool for this, which gives an "not an X.509 certificate" error. I'm guessing the solution has to do with OpenSSL, but I'm not entirely sure what to do with it. Would really appreciate any help with this, since I'm completely clueless with everything crypto-related. Thanks in advance, --Rolf

• Entity Framework 4 Table Valued Function

  - by Imran

  Hi, I am aware that table valued functions are not supported in previous versions of entity framework. I was wondering if this is now supported in EF 4? I cant see my functions in the edm designer so i'm guessing they are not supported unless I am doing something wrong? If they are not supported is there a workaround? Thanks, Imran

• RPXNow user mapping

  - by chelfers

  I am looking into solutions for providing multiple login methods to my site. I found rpxnow.com and they map user accounts from all the different networks. My question is how do they know that I am user1 on twitter and bigdude2 on facebook? I'm hoping it goes beyond email lookups. The end result I want is a unique user in my database no matter what account they sign in with, dupes are a no-no, but most likely inevitable I am guessing.
