• First Windows Phone 7 &ndash; Mobile LOB App.

  - by Richard Jones

  So I spent a couple of hours yesterday building my first Windows 7 Phone Series. application.   I still can’t get used to saying Windows 7 Phone Series.   So I think I’ll just go with WP7.   I must say I’m really impressed.    Calling web-services a breeze laying out User Interface a very straight forward.   I had made called into Dynamics NAV using web-services in under 10 minutes. Working in XAML takes a bit of getting used to,  I’m not trying to-do anything too clever yet. One thing I will point out to transition from one XAML page to the next use this.NavigationService.Navigate(new Uri("/Primary.xaml", UriKind.Relative)); Going from Compact Framework this is equivalent of a Window.Show Its so nice to be able to talk nicely again, about Windows Based Mobile Development!

• Best and easy way to add video to website

  - by Bibo

  I want to add videos to my website. I want to click on images and then to show video in "window" and start playing (popups like lightbox). I just don´t know what is best way to do it. I think one of the way is jQuery. I know that there is easy way with video tag in HTML5 but I want that this could be play on most browsers (not just with support HTML5, but not so old as IE6 :) ) and I don´t want to use flash or silverlight. What options I have? Is jQuery the way? And how can I do this? Thanks

• Xfce Power Manager on Xubuntu 13.10 doesn't work

  - by kirokko

  The problem is that its actually works, but something works with Xfce Power Manager at the same time. For example, I set that if I pressed Suspend button (on my Lenovo B560 its Fn+F2 hotkey) then system ask me what to do. But when Log out window appears, system goes to suspend. Another example is closing the lid. I set it to lock the screen via Xfce Power Manager, but system still goes to suspend. I thought that it might be laptop-mode-tools, but it's not installed. Before 13.10 I had 13.04 and everything were fine.

• Compiz does not work with proprietary nvidia driver

  - by brandizzi

  I have a ThinkPad T420 with an NVidia Quadro video card. It crashes constantly when I close this lid (if you are curious..) and I suspect on a problem with nouveau drivers, so I installed the proprietary NVidia drivers. Howeer, when I install and use this driver, Compiz does not work. If I start a session with uses Compiz, no window manager/decorator is presented. I just can get Metacity working. Does anyone has any idea about what may be causing this problem?

• Source Browsing in FireFox

  - by lavanyadeepak

  Source Browsing in FireFox Just casually observed this a few minutes back with my Mozilla Firefox 3.6.3. When you do a view source of any  page in Internet Explorer it just renders as editable inoperative HTML. However in Firefox the hyperlinks are shown clickable and active. When you click on any hyperlink the most obvious and expected output would be that the target page would appear in one of the new tab in the parent browser. However the View Source window refreshed with the HTML source of the new page. I believe this gesture of Firefox would help us to take a journey back into Lynx Text Browsing in a way.

• How do I set my environment up for TopCoder?

  - by Nils

  I tried out TopCoder today. While I liked the problem, the Java editor didn't work for me. The remote compiling time and the lack of unit tests also made it difficult to complete the task. I ended up coding the solution in Eclipse and the pasting it into the TopCoder window. I tried out EclipseCoder, but it didn't suit my needs either. What tools do you use and how do you hook up your development environment with TopCoder? How does TopCoder handle submissions, and is there any way to speed up the time it takes to process them?

• White lock screen in Gnome 3.4

  - by kedmond

  I'm using Gnome 3.4 on Ubuntu 12.04. I've noticed that my lock screen is white. If I move the mouse, click, or begin typing my password, my wallpaper appears in the background with the password prompt window, as you'd expect. But I don't think the default lock screen is supposed to just be a white screen, is it? How do I fix this? I can't seem to find anyone else with this problem and I don't know what I need to reinstall or change. Thanks!

• ubiquity "hangs" after hitting first "forward" button

  - by bumbling fool

  I've been trying to install Ubuntu but, no matter what I try (wifi connected, wifi not connected, disk blank, disk prepartitioned...), it just "hangs" at the first window (pick your language) with a non-stop hourglass after hitting "forward". This is on a Stinkpad T42. Shouldn't ubiquity at least tell me what's going on? I tried to find a log but /var/log/installer* isn't present. Initiating ubiquity from command line doesn't provide any debug info either. Even when using --debug or other combinations.

• How to implement the light trails for a tron game?

  - by Link

  Well I was creating a TRON style game, but had an issue with creating the actual light trails for the game. What I'm doing currently is I have an array the same size as my window in pixel size, implemented like this: int* collision[800][600]; Then when the bike goes on a certain pixel, it is marked with a 1 for traveled on. However what is the most efficient way to create a working light trail display? I tried to do something like this: int i, j; for(i=0; i<800; i++) for(j=0; j<600; j++) if(*collision[i][j] == 1) Image::applySurface(i, j, trailSurface, gameScreen); But it isn't working properly? It just fills the whole screen with a sprite instead. Whats a better/faster/working way to do this?

• 12.04 indicates filesystem check on next boot, but never does one

  - by pcm

  Just installed 12.04 32 bit on my machine, with 3 drives. When I open a terminal window or ssh in remotely, I see: Welcome to Ubuntu 12.04.1 LTS (GNU/Linux 3.2.0-29-generic-pae i686)  * Documentation:  https://help.ubuntu.com/ *** /dev/sda1 will be checked for errors at next reboot *** *** /dev/sda2 will be checked for errors at next reboot *** *** /dev/sdg1 will be checked for errors at next reboot *** Last login: Fri Aug 31 08:15:41 2012 from .... However, if I reboot, I never see it doing a disk check on boot up, like I used to see with 10.10. Note, after install, I was not seeing the grub menu on boot. I made a ISO disk with BootRepair and now I get the normal grub menu. Any idea as to why the disk check is not happening on boot (I know I can boot a Live CD and then check the disk - I just want the check on boot working)?

• How to integrate Pidgin and Evolution into the message indicator?

  - by Steven Robert Chetwynd

  I upgraded to 12.10, I was using Unity 2d, but as it no longer exists I moved to gnome classic, something in the upgrade seems to have change the message indicator in the "Indicator Applet Complete". How do I integrate Pidgin and Evolution into the message indicator, there is only a button to launch Pidgin, but a new message does not change the colour of the icon or show up in the dropdown part. Also when minimizing Pidgin it minimizes like a normal window instead of minimizing to the applet. There is nothing in the menu for Evolution at all.

• Can't set 1280x1024 with Nvidia Geforce 8400 GS

  - by torbengb

  I've just installed 10.04 LTS using the Windows installer. The system hangs during boot; the splash screen is frozen and it accepts neither Ctrl+Alt+F2 nor Ctrl+Alt+Del, only a hard reset. (I'm a linux noob.) When I edit the default Grub boot option to omit quiet splash, it gets to the point saying * setting sensors limit [OK] _ and there it stays. I can only get to the desktop using the Grub recovery boot option, of course with a lower resolution (800x600) but everything else seems to work fine. As I said, this is a new install. The only thing I've done is to use the Update Manager to get everything up to date, and activate the newest Nvidia driver using the "Hardware drivers" window. I had a similar problem when I installed 9.04 a year ago, and at that time posted this question with an answer that worked - this doesn't work with 10.04. Running nvidia-xconfig to create a new xorg.conf didn't fix it either (while in Recovery boot).

• Kubuntu 11.10: How to remove "Search and launch"

  - by user38489

  Is it possible to remove the "Search and launch" whateveritis from my "desktop"? I've actually tried both Desktop and Netbook modes, but it stays there in both of them. I'm not afraid of editing files in the ~/.kde dir, but I would be really disappointed if this is the only way to do it. [more details/rants] I was able to wipe out several things but I've ended up with a black window that's movable (Alt-click) but not removable. Beside being surprised by the performances, I find Kubuntu extremely unfriendly, and I can't find the logic behind the items of the interface. I've tried to search for documentation, but what I've found is not updated and doesn't include the Netbook interface.

• Environment variable blank inside application

  - by Jake

  I have an environment variable that I've set in ~/.profile with the following line: export APPDIR=/path/to/dir When I log in and load up a terminal, I can verify that the variable is set: $ printenv APPDIR /path/to/dir I'm trying to access this variable from within a Qt application: QString appdir = getenv("APPDIR"); QTWARNING("dir: |" + appdir + "|"); The warning window that pops up shows me: dir: || What is going on here? Am I misunderstanding about how environment variables work in Ubuntu? This is with a C++/Qt App on Ubuntu 11.10 x86.

• WINDOWS 7 DEAD BLUE SCREEN DOES NOT REBOOT OR INSTALL NEW WIN OS

  - by ADAM

  Windows died. So, I installed ubuntu, and have had difficulties downloading apps from the internet like skype or realplayer... etc. And It does not recognize my password. I needed to install drivers for my wireless from cd-rom. It does not show where to save new downloaded files and programs, and app and does not show how to install like windows does. So I would like to go back to windows. Window does not not start up anymore and I can not get safe mode with F8. It goes to black screen only and none of other parameters work when press f8! Any help is highly valued.

• Time tracker for lxde

  - by deshmukh

  I have only recently started using lxde. And I am liking it. It is blazing fast, not-at-all resource hungry and just does what I want. The only thing I am missing is a time tracker tool. I have been using Hamster Time Tracker on gnome for quite some time. In lxde, I can still launch the application. But there are no reminders when the time limit is up, etc. The time tracker is just another window. Is there any way to get hamster working in lxde with notifications for time-up and an icon in the panel, etc.? Alternatively, is there another application like Hamster that will do all that Hamster does and WORKS in lxde?

• Thread problem with XNA C#

  - by Luis

  I'm development a network card game, and for now i've two players connected but there is a problem with one of them, this one can't do anything on the game. Looks that screen was blocked. I'm think that is because a code i used before. That code is: if (InvokeRequired) { this.Invoke(new MethodInvoker(delegate { ... })); return; } The code above is surrounding code to changing Button values, make connection with server and create game window. Without this code a warning is shown. InvalidOperationException was unhandled Cross-thread operation not valid: Control 'startGameButton' accessed from a thread other than the thread it was created on.

• Google Earth-Unsupported graphics card

  - by VIPaul

  I've just installed Google Earth on my PC,which runs Ubuntu 12.04 LTS. When I open Google Earth,a window pop-ups and says:"Unsupported Graphics Card Your graphics card does nor meet the minimum spec required to run Google Earth,which is a 3D accelerated card with shader support.It is strongly recommended that you try running Google Earth on a different machine or in a different rendering mode or upgrade to a newer graphics card.You may continue,but the application is unlikely to work." Maybe you'll say:"Buy a better graphics card!",but I used Google Earth on this machine an year ago,when I had Windows 7 & everything worked well,so my graphics card is good enough. The Linux version has bigger requirements than the Windows one or what???

• XUbuntu: Open file browser via "run command" menu

  - by mbelow

  In older Xubuntu versions, if I entered a path to a directory in the "run command" dialog, a thunar-window was opened showing this directory. I found that to be very handy if I would open f.e.g "/tmp", I just needed to press WindowsKey+r, enter /tmp and press enter, there I was. This was also great for URLs (ftp, http etc) Unfortunately, since 12.04, this doesn't work anymore. It seem as if the "run command" is now integrated with the program finder. It still works when I type "thunar ftp://...." or "thunar /tmp", but it's a bit tedious now. Is there a way to restore the old behavior? Note: I'm running a german localization of Xubuntu - I hope I translated "run command" and "program finder" correctly...

• How can menu bars that require a right click be activated like Ubuntu versions <10.10?

  - by Amos Annoy

  I've noticed that NetworkManager only has a single, left or right, click menu and no longer has an About menu option to show it's splash screen. In fact all the top bar mini short cut icons have been amputated and crippled leaving them with no rights. This severely impacts on our custom aps., similar to FireFox bookmarks, which can no longer be right clicked to bring up a context menu. It is possible to disengage FF's File|Edit|... menu bar from the top by running it in safe-mode so the menu bar is resident in a window, restoring right clicks, but our aps. do not have "safe modes". How can right clicks in menu bars be restored? reference

• Windows 7 Virtual PC - &ldquo;RPC server unavailable&rdquo;

  - by Kelly Jones

  I use Windows 7 Virtual PC on my current project and I often bring home the files, so I can work some in the evenings.  Since my VHDs are large, I’ll only copy the undo disks, saved state, and virtual machine config files from my external drive.  I copy them to a small portable drive and once I get home, I’ll copy them to a large external drive. I’ve done this for over a year, but recently I started getting an error when I tried to start the VPC after the copying was finished.  It would open the initial window with the progress bar, but eventually the bar would stop, turn red, and then the error “RPC server unavailable” would appear.  When I first started seeing these, I’d try again, but no luck. After some testing, it turns out that my small portable drive is apparently going bad, so it was corrupting the files.  Lucky for me, that I never overwrote my good copies with corrupted copies, at least not at both the office and at home.

• Blender 2.64, what are the actual hot-keys for certain actions

  - by Shivan Dragon

  I know this sounds mega lame but I've looked for hotkeys for certain actions, first in the appliation's User Settings (where I didn't find them) then in the official documentation (where I did find some of them but they're not the right ones): http://wiki.blender.org/index.php/Doc:2.4/Manual/3D_interaction/Transform_Control/Manipulators (Ctrl - Alt - S is recommended for Scale, but instead it opens the Save As... window - I think these changed in the latest versions, but they forgot to update the docs) So then, what are the hot keys for: selecting translate manipulator selecting rotate manipulator selecting scale manipulator In Edit mode: select vertex (editing) select edges (editing) select faces (editing) thanks.

• What is the best practice for website design and markup now that mobile browsers are common?

  - by Jonathan Drain

  Back in 2008, smartphones were a small market and it was commonplace for sites to be designed for a fixed width - say, 900px or 960px - with the page centered if the browser window was larger. Many designers said fluid width was better, but since user screens typically varied between 1024x768 and 1920x1080, fluid width allowed longer line length than is optimal for ease of reading, and so many sites (including Stack Exchange) use fixed width. Now that mobile devices are common, what is the the best approach to support both desktop and mobile browsers? Establish a separate mobile site (e.g: mobile.example.com) Serve a different CSS to mobile devices; if so how? Server-side browser sniffing, or a @media rule? Use Javascript or something to adapt the website dynamically to the client? Should all websites be expected to be responsive? Some kind of fluid layout Something else?
