• Ubuntu 12.04 graphics crashing when GVIM opens TEX files

  - by Pdp Molniya

  I am having a little problem everytime I open GVIM to edit *.TEX files.... the menus die, windows jiggle (maximize and minimize quickly) and I get a 'internal error ' crash report from ubuntu (12.04). It says the problem is at /usr/lib/unity/unity-panel-service. Any tips on how to solve this? It might be related to the Latex package of vim (also I get this message when I open gvim (with or without TEX files) on terminal: (gvim:5915): Gnome-WARNING **: Accessibility: failed to find module 'libgail-gnome' which is needed to make this application accessible (gvim:5915): GLib-GObject-WARNING **: cannot retrieve class for invalid (unclassed) type `' Issue is independant of theme I just checked... Thanks a lot for your help! Cheers, Pedro

• How can I optimise ext4 for reliability?

  - by amin

  As ext4 was introduced as more reliable than ext3 with block journals, is there any chance to suppose it 100% reliable? What if enabling block journaling on it, which is disabled by default? As friend's guide to explain my case in more detail: I have an embedded linux device, after installation keyboard and monitor is detached and it works standalone. My duty is to make sure it has reliable file-system so with errors there is no way for manual correct faults on device. I can't force my customer to use a ups with each device to ensure no fault by power-failure. What more can ext4 offer me besides block journaling? Thanks in advance.

• Override Built-In Maverick Keyboard Shortcuts

  - by jrc03c

  Having used the Command+M keyboard shortcut to minimize windows in OS X, I'd like to use the same functionality in Ubuntu 10.10. When I try, though, it only brings up the "communications" section of the indicator applet; like so: In the Keyboard Shortcuts preferences, I have set as the minimize shortcut "Mod4+M", which I got by capturing the Apple "Command" key and the "M" key. I find no other shortcut using this key combination in Keyboard Shortcuts, and yet I cannot get the window to minimize when using it. Does anyone know how to override Ubuntu's default usage of this key combination? Thanks!

• What workflow engines are companies using and would you use it again? [on hold]

  - by cbmeeks

  I've been asked to find out "what's out there" when it comes to workflow engines. We have projects where a workflow based development environment makes sense. I've looked a little into jBPM but it seemed to have a steep learning curve. Google seems to take me to commercial products or products that I think are open source but instead have very limited "community editions". I could simply be searching for the wrong terms. What I would like to know are what actual workflow based products have you used at your company and to what degree of success or failure was it? Would you use it again? Thanks.

• Accidentally hit shortcut and lost text in web browser. Can it be disabled?

  - by uniomni

  I have noticed that I occasionally hit some shortcut while typing that either kills the browser or otherwise causes me to lose e.g. a post I am writing. This typically happens if I type while on a bumpy road or something like that. It also just happened to my eight year old daughter ;-( I think the shortcut in question is CTRL-w which (at least in Firefox) closes the current tab and consequently whatever content is being written. I would like to know if anyone has noticed this and if someone has a solution e.g. a way to disable "dangerous" shortcuts if at all possible. Many thanks Ole (uniomni)

• Install 12.10 using Logitech Keyboard and mouse with bluetooth dongle

  - by Ryan

  I'm trying to install 12.10 on my system, but my mouse and keyboard are not working during installation. I use the Logitech MX5500 Bluetooth mouse+keyboard combo with a Bluetooth dongle. My keyboard and mouse work in my UEFI bios, and during the Windows 7/8 installation. My keyboard also works in the Ubuntu screen that allows me to set options, install, use the live cd, etc, before boot. I'm wondering if anyone knows a way to get this dongle working during the installation process so that I can actually install 12.10. Thanks.

• joomla sometimes messes up urls, probably cache involved

  - by Bakaburg

  Is a bit i'm having this problem and i really cannot get the hang of it... Every once in while my joomla site messes up links url and for example from something like this: http://www.sism.org/index.php?option=com_comprofiler&task=userslist&listid=4&Itemid=123 it becomes like this: http://www.sism.org/index.php/component/k2/administrator/components/com_dump/assets/css/images/stories/inrilievo/sism/htm/index.php?option=com_comprofiler&task=userslist&listid=4&Itemid=123 the new page has the right content but there are no css and other linked resources. Usually i solve the problem by deleting all the cache and turning it off and on again. Of course this is pretty annoying especially for my association. Does any one have any clue on this? Watching the URLs the components involved seems to be K2 and Jdump. Thanks

• Rhythmbox iPod Issues?

  - by Jonathan Jones

  basically, when I try and drag a song from my library to any one of my iPods (Classic (2.0.4 Mac), Touch (3.1.2. (7D11)) and Shuffle), nothing happens. It would appear that everything went ok, but... when I go to the iPod's library, the song is not there. When trying to transfer the file, there is no error etc. to suggest something that went wrong, and so I can't file a bug report on Launchpad etc. Does anyone know what could be wrong? Cheers guys! EDIT: I forgot to add that I'm running a 64-bit install of Ubuntu 12.04LTS and that Amarok and gtkpod don't even recognise that any devices are plugged in. Thanks.

• Define outgoing ip address when using ssh

  - by Mark

  I have an ubuntu server machine (12.04) with 4 IP addresses for different websites that require unique ssl certificates. I sometimes ssh out from this box and the box I am going to I have to tell it what IP address I will be coming from. How do I specify which of the 4 ip addresses I want to use as my outgoing IP address? If i do an ifconfig it appears that I am going out as the last ipaddress. I guess you would want to specify either the address or the interface.... Thanks in advance! -Mark

• trying to install ubuntu touch to nexus 4 - can't connect device (14.04 in virtual box on mac)

  - by Fiona Cox

  I'm trying to install Ubuntu touch to a nexus 4. I've followed all the steps so far, downloaded the packages and gotten the phone ready, but now I got to the step of connecting it to the computer [under 'Enable USB Debugging'], but it's not listed when I try $ adb devices (I tried the 'adb kill-server' command first too, but nothing is listed). I'm sure it's something simple I'm forgetting, but can anyone help please? I have debugging enabled. Running Trusty in VirtualBox on MacBook. Thanks!

• How do you know when to change jobs? [closed]

  - by dustyprogrammer

  Possible Duplicate: When do you know it's time to move on from your current job? I have been working for a couple years now. I just want to know what people think about leaving one company for another, or to start looking around for other positions. I tend to use people's resumes as a guideline for when to change from one company to another. I am approaching, the time in my life where most of those people I look too, move away from their first position to pursue others. I know that isn't something good to base my decisions on what other do. I was wondering when is it time to move companies. I am currently happy at my position, and I am learning tons. Its just something I have been seeing a lot, I would like to get a feel for what people think. Thanks.

• How to reload Variety wallpaper changer?

  - by mayur

  I have installed Variety desktop wallpaper changer. Its a good app. But sometimes when I start Ubuntu and login to my account it fails to load. I try to manually start the app by clicking on variety icon, but doesnt work. I tried alt+F2 and enter 'killall gnome-panel' but nothing seems to happen. I checked in my startup applications window, variety is present there to start when Ubuntu starts. but then why it does not start always? Restarting my pc is the only solution then. Is there a way that I can reload Variety without logging off or restarting Ubuntu? Thanks in advance.

• Font displays differently in Firefox vs. Chrome

  - by Goro

  It seems that my menu bar is displayed with a different font stretch in Firefox than it is in Chrome. See the following: Here is the CSS applied to this element: font-variant: small-caps; font-size:13px; letter-spacing: 0px; font-family: Arial; font-stretch: normal; text-decoration: none; As far as I can tell everything regarding that font is exactly the same, yet they still display differently (see pic). Any ideas? Thanks,

• Good Intro to Computer Science Book for FE Developer [on hold]

  - by Squirkle

  I am a JavaScript developer/architect who, like many developers these days, did not come from a Computer Science background (I studied Philosophy at a liberal arts college), but instead learned development by actually building applications, and by reading books explaining language grammars, design patterns, and best practices. I have never felt that my ignorance of CS concepts has hurt my ability to build great apps or find employment. Recently, however, I have felt the itch to grow in this direction. Do you have any suggestions for some good introductory CS resources/books? I know that Computer Science is a huge field and my question is very general, but I am looking for a 101-type survey of the high-level concepts, from which I can branch off into more specific areas of study. Thanks!

• Monitor not turning off when screen saver is on

  - by Elad92

  I installed Ubuntu for the first time 3 weeks ago and I really love it. I have Ubuntu 12.04. My only problem is that when screen saver is on, it just shows blank screen, and not turning off the monitor, so my monitor is always on. I have Samsung E2220 - 22". I looked over the web and I found this command: sudo xset dpms force off This command shuts down my screen so I don't see a reason why the screen saver can't shut it down. Thanks a lot! Elad

• Empathy auto accept group chat invite

  - by Sivaji

  I'm using empathy 2.34.0 as chat client for account hosted on Google app (server talk.google.com). I'm happy with the features that empathy provides and integration with Google chat, however for group chat when the request is received I need to click on "join" button showed in popup to get started. This makes sense but I would to know if there is any way to automatically join the chat room without clicking the "join" button as I use it only with trusted uses. Besides the messages shared after the invite request and before my entry to chat room is not accessible to me. I looked around the empathy settings but couldn't find anything useful, wondering if I can get some help from here. Thanks.

• How to fix "error: unknown file system" on all available partitions

  - by Jonathan

  I've had a running problem with removing Linux from my Windows 7 laptop. Initially, it was installed as a dual-boot, and worked well. To remove, I deleted the partitions on my laptop. This removed grub, and I was left with needing to enter: set root=... set prefix=... insmod normal normal each restart. I didn't restore the Windows boot-loader and have since re-partitioned my drive. Now, upon reaching the command prompt screen, an ls query showshd0, with three partitions, but none of them have a recognizable boot-loader as each returns with error: unknown file system. Booting from a Windows 7 rescue disk doesn't seem to work, as it sends me to the same command prompt terminal. All I'm looking to do is restore the boot-loader, either grub or Windows 7. Any help would be appreciated. Thanks in advance.

• Acer Aspire microphone issue

  - by Dr_Bunsen

  I have got an Acer Aspire 7750G: More info It has been running Ubuntu since I bought the laptop (12.10 as of now), but a few updates ago, I lost my microphone. It doesn't recognise the internal mic or the mic jack (although alsa seems to recognise it). I have been looking around, and I fixed it, but this was only temporary, after a reboot my mic was gone again. I haven't been able to find the fix, so I wanted to know whatever you guys know what I have to do to fix this. Thanks in advance.

• Add in the header of the license type is enough to say: "my code is licensed"? (Open-source)

  - by silverfox

  I do not know if this is the correct place to ask this stackexchange. Note: If a moderator can move to the correct place (if I am in the inappropriate site SE) I read on various sites about licenses. I did just put the license type in the header file (in my case the javascript file - open-source). /* * "codeName" "version" * http://officialsite.com/ * * Copyright 2012 "codeName" * Released under the "LICENSE NAME" license * http://officialsite.com/LICENSE NAME */ javascript code ... In the same folder I leave a copy of the license. The listing of the folder looks like this: * codeName.js * LICENSE In the file LICENSE would leave my code uses. What nobody says is if it is enough to say my code is licensed (the case of an open-source). Or is something more required? Sorry for the bad English. Thanks.

• What is the best database design for managing historical information? [closed]

  - by Emmad Kareem

  Say you have a Person table with columns such as: ID, FirstName, LastName, BirthCountry, ...etc. And you want to keep track of changes on such a table. For example, the user may want to see previous names of a person or previous addresses, etc. The normalized way is to keep names in separate table, addresses in a separate table,...etc. and the main person table will contain only the information that you are not interested in monitoring changes for (such information will be updated in place). The problem I see here, aside form the coding hassle due to the extensive number of joins required in a real-life situation, is that I have never seen this type of design in any real application (maybe because most did not provide this feature!). So, is there a better way to design this? Thanks.
