• Gtk theme change doesn't apply to kde apps?

  - by Stefan Monov

  I changed the systemwide ambiance theme a bit (specifically the scrollbar css), and this works fine in gtk apps, but in kde apps nothing has changed. They still have the vanilla ambiance look. I tried rebooting too. Btw I've disabled overlay scrollbars. I looked at this question: Why don't Qt4 apps in Lubuntu pick up the GTK theme? and tried setting the Gtk+ theme in qtconfig but that didn't help. The look remains the same. Changing the theme in qtconfig to another one, such as QtCurve, does have an effect though.

• Network programming under windows: is WSA functions can be more complete than pSock functions [on hold]

  - by Kane

  I plan to make a set of classic socket functions to simplify their usages. Since i work under windows and linux indifferently i usually make it portable (it's not my first version of this set of functions), but i want to do something different this time and dedicate one version to windows, and one other to linux. With that i wonder for the windows version, if the WSA* functions can have any interest using them instead of the psock ones. I have found nothing about a comparison between them, so if any of you have any idea, suggestion, link or benchmark ?

• Material tiling and offset in unity

  - by Simran kaur

  Ambiguity: What exactly is the difference between Tiling the material and Offset of material? Need to do: I need the material to be repeated n times on the object where I need to set the value of n via script.How do I do it? It seems to happen through Tiling(tried via inspector) but again what is difference between mainTextureOffset and setTextureOffset? Tried: Following is the line of code that I tried to repeat the texture n number of times on an object(repeat across the width of object), but it does nothing significant that I can see.

• Looking for bug tracking software

  - by Shelton

  I'm looking for a bug/issue tracking system that can: Integrate with lots of other services. Basecamp, Beanstalk, etc. Integrate popular CMSs, such as WordPress, so the client can enter a ticket from the system that is familiar to them and not have one more login to worry about. Generate reports for my own purposes. Bonus if there's an iPhone app. Doesn't require additional development on my end (I have plenty of money and no time). I've already looked into Lighthouse and ZenDesk -- both are solid offerings -- but don't see what I need out of the box. I'd have to build CMS plug-ins. And I've looked through WP plug-ins for bug tracking software, but nothing I've found integrates with these products. Anyone know of something that meets these requirements without additional development, or am I stuck putting my business on hold to get this piece in place myself?

• Cinnamon on Ubuntu 12.04 stoped working after menu edditing

  - by Presbitero

  I have recently installed cinnamon on ubuntu 12.04 with success. After installing MS Office with wine my menu got messy so I tried to edit it with alacarte. After having found out that alacarte is not the proper way to edit it, I right clicked on the menu icon to edit. After just a few editing steps it breaks and cinnamon stopped working (no menus, no desktop icons, no applets, no window decoration, nothing). Now, when I login with cinnamon I just get the background image. I can login with gnome though. I have tried to completely remove cinnamon and nemo and reinstall it but it didn't help. I have no idea of how to get any king of diagnostics so if you ask something please explain how to do it or post a link with explanations. Many thanks for the help, I hope I will not need to format the pc again to make it work.

• 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.

• Unable to boot 12.04 server: no LVM activated and impossible to mount /

  - by baronKarza

  I'm stuck in the Busy Box shell after upgrading from Ubuntu server 11.10 to Ubuntu server 12.04 64 bit. During the booting phase the system hangs while mounting root filesystem. My system is so configured: /dev/sda1 -- /boot /dev/mapper/vg-lv_root /dev/mapper/vg-lv_var /dev/mapper/vg-lv_tmp When the boot process fails and I'm forwarded to the busybox shell, if I type vgchange -ay I can mount my volumes and all it's OK. But it does not enable LVM automatically so that it is impossible to mount root, var, and tmp. I tried to start with a Knoppix, chroot, reinstall (aptitude) both kernel and lvm2 as suggested by this tread "Fixing unbootable installation on LVM root from Desktop LiveCD": nothing changed. I can't figure out what is the problem. Any suggestion is welcome. Thanks in advance.

• Why ~/.bash_profile is not getting sourced when opening a terminal in Ubuntu 11.04?

  - by Viriato

  Problem I have an Ubuntu 11.04 Virtual Machine and I wanted to set up my Java development environment. I did as follows sudo apt-get install openjdk-6-jdk Added the following entries to ~/.bash_profile export JAVA_HOME=/usr/lib/jvm/java-6-openjdk export PATH=$PATH:$JAVA_HOME/bin Save the changes and exit Open up a terminal again and typed the following echo $JAVA_HOME (blank) echo $PATH (displayed, but not the JAVA_HOME value) Nothing happened, like if the export of JAVA_HOME and it's addition to the PATH were never done. Solution I had to go to ~/.bashrc and add the following entry towards the end of file #Source bash_profile to set JAVA_HOME and add it to the PATH because for some reason is not being picked up . ~/.bash_profile Questions Why did I have to do that? I thought bash_profile, bash_login or profile in absence of those two get executed first before bashrc. Was in this case my terminal a non-login shell? If so, why when doing su after the terminal and putting the password it did not execute profile where I had also set the exports mentioned above?

• Best approach to get clicked objects from a display list (2D)

  - by Ixx

  I'm implementing a display list to manage my visuals on screen. I want to know which object is clicked. My objects already have z-order variable. With my current knowledge (almost nothing) the only thing which comes to my mind is make a linear search and get all the objects which contains the clicked point. And then select the object with the highest z-order. But I know there are far better approaches. I think it's something with trees (binary search?). - container display objects and search recursively? just don't know where to start looking, for this concrete case. Any hint link or concrete solution is welcome.

• How to write loosely coupled classes in node.js

  - by lortabac

  I am trying to understand how to design node.js applications, but it seems there is something I can't grasp about asynchronous programming. Let's say my application needs to access a database. In a synchronous environment I would implement a data access class with a read() method, returning an associative array. In node.js, because code is executed asynchronously, this method can't return a value, so, after execution, it will have to "do" something as a side effect. It will then contain at least 1 line of extraneous code which has nothing to do with data access. Multiply this for all methods and all classes and you will very soon have an unmanageable "code soup". What is the proper way to handle this problem? Am I approaching it the wrong way?

• Internet keep dropping in Ubuntu 12.04

  - by Kokuryuu

  I am having an issue with my Ubuntu, I keep getting "server not found" errors when I try to go online, I have tried pinging my DNS and Goggle, and it seems like no packets are dropped, but still my Internet is not working Also my other PCs in the house have working Internet connection. I am sure there is no firewall active here, also nothing on my router is blocking, and I checked cables. I have no issues in the same PC in Windows. It is only in Ubuntu. Any ideas?

• Ubuntu will not load up from my USB

  - by Ryan Mungwira

  I have a Sony Vaio Duo 13 and I am trying to get Ubuntu 13.10 to run on a partition on my Ultrabook but it will not load up from the USB drive. It goes to the black screen that asks if you just want to Try Ubuntu or if you want to Install it. I click just to try and it will not load. It acts like it is going to start up but then it just goes to a blank black screen and then I have to a hard restart. It does that when I click install as well. And I have tried disabling the Secure Install on my computer as well and nothing happens! What do I do?!?

• Why use C++ when C works for large projects equally well?

  - by Karl

  Before I start, please DO NOT make this into a C vs C++ flamewar. This question has nothing to do with which language is better or not. Period. I have read that C++ is said to be fit for large projects. After all, it makes managing code easier. OO and other features, for example the STL. But then why use C++ when C works equally well for large projects? Take the example of the Linux kernel. Or GNOME. Or even Windows I guess, it is written in C right? So why bother at all with the complexity of C++ (templates and all that), when C works well and this is not just a statement, but proper examples have been quoted. If it works for projects of magnitude of the kernel, why is C++ preferred or why is C not used for almost all projects?

• Reliability Monitor is the Best Windows Troubleshooting Tool You Aren’t Using

  - by The Geek

  When it comes to hidden gems in Windows, nothing beats the Reliability monitor tool, hidden behind a link inside of another tool that you don’t use either. Why Microsoft doesn’t shine more light on this really useful troubleshooting tool, we’ll never know. Reliability Monitor tracks the history of your computer — any time an application crashes, hangs, or Windows gives you a blue screen of death. It also tracks other important events, like when software is installed, or Windows Updates loads a new patch. It’s an extremely useful tool. And yes, it’s in Windows 7 and 8… and even 8.1. It might be in Vista, but who uses that anymore?

• The evils of #region

  - by DarrenFieldhouse

  I’m not a big fan of #region, I use it occasionally but generally try to avoid it. It’s always frustrating to open a code file and be presented with nothing but collapsed regions – sure, it looks neat (and lets face, more than a few programmers are a little OCD) but I want to see the code, that’s why I opened the file in the first place! Don’t worry, I’m not going off on a rant, I just want to direct you to a much more level headed explanation of The Problem With Code Folding. I couldn’t agree more.

• Deploying Asp.net MVC web application [migrated]

  - by Pankaj Upadhyay

  I have been trying to find a neat tutorial, guide or step by step instructions for deploying an Asp.net MVC3 webapp but have found nothing so far. Everyone talks about his version of the stroy and different type of MVC versions. Right now, I have build a simple Asp.net MVC web application which i need to deploy on my shared hosting account. In a very simple manner, I need to know which files should i copy. Do i upload everything in my webproject directory to the server including the controller directory, views, models, content and bin directory ?. What about the Global.asax, web.config, packages.config, myapp.publish.xml. In short, I have no idea which files should be uploaded and which should be not. I am sure of one thing that i need few(MVC and Razor dlls) following dlls in bin directory. Just treat me as someone who has never deployed any website NOTE:- I don't have VS SP1 installed and it doesn't install either. Basically i need a manual procedure.

• Is there a consolidated API reference for the Firefox browser.xul?

  - by cxw

  I have used Greasemonkey many times and am stepping up to Firefox extension development. Is there a consolidated reference for the variables, functions, and anything else that is available to overlays on browser.xul? Besides gBrowser, I note from the source that there are at least gNavToolbox, gURLBar, and gNavigatorBundle and would like more information about what services they provide. I have looked through the XUL School and XUL Tutorial on MDN, searched MozillaZine, and browsed the Jetpack documentation without finding anything but references to gBrowser. I have also looked at the code snippets referenced elsewhere (e.g.) and found specifics, but nothing that puts all the information together in one place. Is there such a reference?

• Problems with No-IP redirecting

  - by user171156

  I am setting up a webserver on my ubuntu desktop 13.04, everything is working fine except; When trying to access the server through the external host using no-ip, it gives the original index created by apache on setup. While when I try to connect to the server via my real IP address from externally, it goes to the correct index. I have been trying to figure out what the issue is on this problem as nothing is working because of that bad redirect, I'm wondering if anyone of you could help me out, or advise me in the right path. Thank you very much! PS; If more info needed I'll provide, but this should explain it all.

• What are the benefits of a disk install vs. Wubi? And can I migrate my settings easily?

  - by Alex Bixel

  I chose to do the Wubi install because it was short, simple, and easy to reverse (no messing with partitions required). To be honest, I can handle the lack of a hibernate function. I haven't really heard many other benefits of installing on a separate partition than hibernation and negligibly faster hard disk read/write. Yet almost everyone I encounter seems to have opted for the disk installation. Are there more benefits I should be aware of, especially as a college student who wants a fast, efficient machine for documents, web browsing, etc. (nothing big like gaming, I can run that on Windows)? Also, I have a fair amount of settings and packages installed that I spent a bit of time on and would rather not have to do again. Is there any way I can migrate all of these settings from the virtual disk on my C:/ drive (Wubi installation) to the disc installation in another partition? (I have a 16GB USB drive if that'll do the trick)

• Cannot save password in Evolution?

  - by mhmdrizmi

  I'm using evolution in lubuntu. Configuring the email accounts is OK. Then a window appears asking for the mail password. There is an option to add the password to the keyring. When this is checked nothing happens. The window doesn't close either. When I repeat the same steps with the option to add the password unchecked, it works fine. But I have to enter the passwords every time I start evolution. I guess it's a problem with the keyring (just a guess). How can I fix this ?

• Can Google Translate's audio files be used in a game?

  - by ashes999

  For my game, I need text-to-speech. Since it's Android, I decided to settle for MP3s, since the range of words spoken is few. For my prototype, I'm using Google Translate to generate the audio since it has awesome pronounciation across multiple languages. But can I use it in production? What if I sell my game for $1 on the app store? All I can find on SE is that the API may be LGPL, and that the licensing page mentions the API is only available for academic research -- nothing more. My usage is a bit different; I'm actually capturing the audio bits and using those instead. I'm curious to know the license for this; I can't find anything with my Google-fu.

• Certain Keyboard shortcuts not working

  - by user968808

  I have the logitech k800 keyboard but can't seem to get certain shortcuts working. I change in the keyboard shortcut settings volume up and down and it actually takes the key assignment but does not take effect when trying to use. After trying for a while I also tried to create a custom shortcut after with the command amixer -q sset Master 10%- Finally I tried changing the command to touch a file to see if it is actually responding but nothing. How can it take the key as an assignment in the shortcut settings but not to actually respond when pressing it. FYI other keys work like mute, next track etc. There is just 3 keys shortcuts not currently working. Thanks

• How do I change the "Default" password

  - by Allwar

  hi, here's my problem. When I log in I'm beeing asked for a password connecting to the internet which is strange because I'm the only user and the admin. I have auto log in and it never asks for passwords, (except when i do administrative tasks.) I have looked in the menu (System -- preferences, but i can't find any topic that say's passwords or similar. the only place where I have found a way to change my password is my user ((System -- preferences -- user and groups). I did try to take screenshots but nothing happened, which also is strange. I'm running ubuntu 10.04 LTS Desktop on my Asus 1201n (12").
