• Installing 12.10 messed up Xorg

  - by Ghost

  So I finally decided to upgrade from 12.04 and now my ubuntu install has been rendered unusable. I'm getting the "no screens detected" error from xorg in the console, and no mattr how many times I reinstall it xorg keeps throwing the same errors. I already had to do a bunch of hacks like nomodeset just to get to the console, else I would get an infinite tabulator after the purple boot screen. The machine has a 4200HD IGP, I even tried installing fglrx legacy (4xxx series and below are not supported in regular fglrx anymore) which was a subpar driver in 12.04 but in hopes that the machine would at least work, but nope, nothing at all. Anyone had the same problem? how do I fix it? EDIT: just wanted to add that I upgraded to 13.04 and it didn't solve anything, in fact it might have broken things even further.

• Key Windows Phone Development Concepts

  - by Tim Murphy

  As I am doing more development in and out of the enterprise arena for Windows Phone I decide I would study for the 70-599 test.  I generally take certification tests as a way to force me to dig deeper into a technology.  Between the development and studying I decided it would be good to put a post together of key development features in Windows Phone 7 environment.  Contrary to popular belief the launch of Windows Phone 8 will not obsolete Windows Phone 7 development.  With the launch of 7.8 coming shortly and people who will remain on 7.X for the foreseeable future there are still consumers needing these apps so don’t throw out the baby with the bath water. PhoneApplicationService This is a class that every Windows Phone developer needs to become familiar with.  When it comes to application state this is your go to repository.  It also contains events that help with management of your application’s lifecycle.  You can access it like the following code sample. 1: PhoneApplicationService.Current.State["ValidUser"] = userResult; DeviceNetworkInformation This class allows you to determine the connectivity of the device and be notified when something changes with that connectivity.  If you are making web service calls you will want to check here before firing off. I have found that this class doesn’t actually work very well for determining if you have internet access.  You are better of using the following code where IsConnectedToInternet is an App level property. private void Application_Launching(object sender, LaunchingEventArgs e){ // Validate user access if (Microsoft.Phone.Net.NetworkInformation.NetworkInterface.NetworkInterfaceType != Microsoft.Phone.Net.NetworkInformation.NetworkInterfaceType.None) { IsConnectedToInternet = true; } else { IsConnectedToInternet = false; } NetworkChange.NetworkAddressChanged += new NetworkAddressChangedEventHandler(NetworkChange_NetworkAddressChanged);}void NetworkChange_NetworkAddressChanged(object sender, EventArgs e){ IsConnectedToInternet = (Microsoft.Phone.Net.NetworkInformation.NetworkInterface.NetworkInterfaceType != Microsoft.Phone.Net.NetworkInformation.NetworkInterfaceType.None);} Push Notification Push notification allows your application to receive notifications in a way that reduces the application’s power needs. This MSDN article is a good place to get the basics of push notification, but you can see the essential concept in the diagram below.  There are three types of push notification: toast, Tile and raw.  The first two work regardless of the state of the application where as raw messages are discarded if your application is not running.   Live Tiles Live tiles are one of the main differentiators of the Windows Phone platform.  They allow users to find information at a glance from their start screen without navigating into individual apps.  Knowing how to implement them can be a great boost to the attractiveness of your application. The simplest step-by-step explanation for creating live tiles is here. Local Database While your application really only has Isolated Storage as a data store there are some ways of giving you database functionality to develop against.  There are a number of open source ORM style solutions.  Probably the best and most native way I have found is to use LINQ to SQL.  It does take a significant amount of setup, but the ease of use once it is configured is worth the cost.  Rather than repeat the full concepts here I will point you to a post that I wrote previously. Tasks (Bing, Email) Leveraging built in features of the Windows Phone platform is an easy way to add functionality that would be expensive to develop on your own.  The classes that you need to make yourself familiar with are BingMapsDirectionsTask and EmailComposeTask.  This will allow your application to supply directions and give the user an email path to relay information to friends and associates. Event model Because of the ability for users to switch quickly to switch to other apps or the home screen is just one reason why knowing the Windows Phone event model is important.  You need to be able to save data so that if a user gets a phone call they can come back to exactly where they were in your application.  This means that you will need to handle such events as Launching, Activated, Deactivated and Closing at an application level.  You will probably also want to get familiar with the OnNavigatedTo and OnNavigatedFrom events at the page level.  These will give you an opportunity to save data as a user navigates through your app. Summary This is just a small portion of the concepts that you will use while building Windows Phone apps, but these are some of the most critical.  With the launch of Windows Phone 8 this list will probably expand.  Take the time to investigate these topics further and try them out in your apps. del.icio.us Tags: Windows Phone 7,Windows Phone,WP7,Software Development,70-599

• What is a good network for full-page rich ads?

  - by Vishnu

  I'm currently developing a website where users will be able to upload content. I would like to be able to show a full-page ad whenever someone tries to view the content. The ad should take up most of the screen, and I should be able to have a "continue to the content --" link at the top. Preferably, I want something like what is currently on Forbes (if you haven't seen it, here: http://www.forbes.com/fdc/welcome.shtml but with an ad in the black area). Of course, the most revenue is the best. Thanks.

• a brand new FS based on a database without using fuse

  - by Devrim

  hi all, To serve millions of files out of a single directory, being able to connect to a drive from hundreds of endpoints, and for some other reasons (to avoid gluster/nfs/all fs based networking solutions), I want to evaluate the possibility of making a filesystem that's based on a mongodb (or any other). Basically, it works like fusefs, every single file is kept in mongo gridfs. In theory, I do, mount mongodbfs /mountPoint mongodb://localhost then when i say touch /mountPoint/test.txt this file is inserted into mongodb. This FS will also store uid/gid and perms with the file, we can throw hundreds of servers to it, and no useradd will be necessary. I'm not thinking to include all the features of FS, just the ones we need. My question is, how do I start my quest in finding resources, books, links, people, developers who'd help me implement this? at least a proof of concept. Is it feasible? What should I expect as a timeline for such undertaking? Please only think about gazillion small files and folders.

• When Your ASP.NET MVC Custom Error Doesn't Render...

  You've put [HandleError] on your controller and you've set <customErrors mode="On"> in the web.config file. So why do you still see the yellow screen of death?

• How do you dual boot Windows 7/8 seperatly with GRUB?

  - by Aaron

  I installed the beta version of Windows 8 and re-installed GRUB. When I boot my computer and select Windows 7, I get the new Windows 8 booting screen asking to boot between either Windows 7 or 8. If I choose Windows 7, my computer then restarts and I have to select Windows 7 again in order to boot into 7. But if I choose Windows 8 it boots right up. I understand I can choose which OS to boot by default, but I want my GRUB options to be the only way to choose between OS's. So my question is, how can I set this up so that when I click on Windows 7, I go there, and when I select Windows 8, I boot 8?

• Macbook Pro (2011) Install of 12.10

  - by William Fleming

  I have installed Ubuntu on another partition on my macbook only to find when i boot using refit im greeted with a screen that reads Missing Operating System I have chosen to install grub on the root partition so i assume after the EFI boot-loader has done its stuff it will then load grub in the " / " partition. Any thoughts on this i couldn't find anyone with this problem. I can only assume its a problem with the GRUB install on the partition. But i have tried to reinstall it and it did not work....? Any thoughts would greatly appreciated. Bill

• How can I get a 1920x1080 resolution?

  - by Sam T.

  I a newbie Linux and have just installed Ubuntu in a dual boot with Windows 7. I love the interface of Ubuntu but unfortunately I can only get a 800x600 or 1024x728 resolution with black bars all around the screen. I have an nVidia GTX 570 graphics card and an Asus 1080p 23" monitor. What may be of note is that I had to use the nomodeset command on installation of the boot would get stuck at a line with "nouveau", which I understand is to do with the drivers. Additionally, when I type in xrandr to the terminal, it comes up with the error message "failed to get size of gamma for output default". I guess what I am looking for here is someone who could explain to me really simply the steps I have to take to get a full 1080p resolution, at which point I am sure i will become a great fan of the OS! Thanks in advance, Sam T.

• Xubuntu all Icons disappeared

  - by user1392185

  I'm running Xubuntu 12.04.1 with kernel Xen4.1-amd64 and the following problem is mine: Nearly all icons have been replaced by the default "no icon available"-icon, even on the login screen and the all icons in software like e.g. Firefox and the icons I manually assigned to launchers, too. Changing the icon theme does not seem to affect this. The only icons that did not disappear are: LibreOffice, gThumb, Simplescan, Ristretto and in the XFCE menu office, tools and graphics. How could I bring the icons back? EDIT: When I tried to use Ristretto the following error showed up: Could not load image-loader module /usr/lib/x68_64-linux-gnu/gdk-pixbuf-2.0/2.12.0/loaders/libpixbufloader-png.so Unable to open shared-object-file I/O error (Had to translate this to English.)

• Transcoding media server streaming to the iPhone

  - by pilif

  I have a huge collection of videos in different formats, but with one thing in common: They are not playable on an iPhone (or iPod Touch). Instead of complaining about Apple's IMHO broken world view ("there are no video formats but quicktime and mp4"), I wonder if there's a solution out there that allows streaming these different videos to the iPhone. This means that the source media needs to be transcoded on the fly. I already tried a few solutions out there, but with varying success: PS3 Media Server kind of worked, but only once and only for one single file. TVersity is said to work, but it requires UAC to be disabled and I don't see any need for this. The solution I'm looking for should run on Windows 2008 Server or Linux. I just can't believe that there's nothing out there that would allow me to stream my huge video collection on my iPhone (we're talking Wifi here, not 3G). After looking at the answers provided and after retrying TVersity without much success, I gave Orb another try and while the web interface failed to work for me, the iPhone Application (I tried the free one at first) actually worked flawlessly. And not only that, it also manages to convert the streams on-the-fly, so you don't have to wait for the transcoding process to finish before playback starts. On my 2.26 Ghz MacMini Server, this worked even with 1080p material. For Windows 2008 Server users out there: Remember to install the Desktop Experience Feature in the Server Manager if you intend this to work. Of all the stuff I had a look at, this really provided instant-success - even though I'm now probably sending the contents of my harddrive to orb's central server (sigh)

• Problems while upgrading from 11.10 to 12.04

  - by Jignesh

  I was upgrading from ubuntu 11.10 to ubuntu 12.04 using the alternate cd method. Everything went fine upto installing upgrades, but during the cleanup phase , it asked me to remove obselete packages or not, and to close all open applications. I used Alt+Tab to view open applications, and then it just hanged, I could only move mouse ,entire screen got blank, and I was forced to restart , leaving the upgrade in middle. After restarting my ubuntu 12.04 is working fine , I think ubuntu got upgraded as only cleanup and restarting phases were remaining when I restarted, can there be problems with this ubuntu, or is this fine ?

• Alternative to | more to display error results page by page

  - by Lane

  The command psql -d template_postgis2 -f /usr/share/postgresql/9.1/contrib/postgis-2.1/postgis.sql returns a list of errors that is too long to be displayed by scrolling up to the beginning of the error. I tried the same command with "| more" and "| less" added up at the end of the command but it does not display the message page by page as it should. I also tried to put the output in a file with "> file.txt" but I do not get in this new file what is displayed on the screen!! I don't understand why. I guess i can't do this with a psql command?? Is there any other way to get all the error message? Thanks for your help!

• assistance recovering/reinstalling/installing ubuntu and win7

  - by razzrat

  New computer with Windows 7 installed, I defrag, shrink, re-boot from Ubuntu LiveUSB, go to gparted and look at partitions before installing Ubuntu....for some reason Win7 is still taking up 400G of my HD! I resized partition down with gparted, exit and yes of course I can't boot into Windows. When I go to install Ubuntu in new large unallocated space I get a blank screen at the point you are asked what kind of installation you want. I have Ubuntu 12.04 LiveUSB, Windows 7 re-installation disk and driver disks also. The HDD currently has 3 allocated partitions: 'diag' fat16, 'recovery' ntfs and 'OS' ntfs which has a red '!' next to it.

• How do I get movies to work in my dual CD/DVD computer?

  - by user289178

  I have an older Dell Optiplex GX620. It has an IDE CD drive and an IDE DVD drive. I cannot seem to get Ubuntu 14.04 to allow movies to play. I've tried installing libdvdcss2 as well as the libdvdread4. VLC was installed last, but each time I attempt to play a movie, the player flashed briefly, then goes back to the initial screen like I didn't even have a DVD in the drive. I'm fairly new to the linux world, so any/all suggestions would be helpful.

• Rapid Application Development, good, bad or ugly?

  - by chrisw

  I have been working for such a shop for the past three years and I know deep down it cannot be like this everywhere. When I think of Rapid Application Development I immediately think programming without fore-thought. For example, when my company decides to come out with a new product, they don't do any type of relationship mapping, no ER diagrams, no round table discussions on expandability. No, the senior developer that ends up working on the product puts together a screen shot walk-through of the application to show to the client. Once the client signs off on the project work is underway by the senior developer. Now you have a senior developer (I use that term "senior" loosely) coding the application in under a week with no unit testing. Well I guess the good to this is it keeps programmers employed due to the enormous amount of unforeseen "features" in the newly created application. Have any of you dealt with a company like this? If you did how did you preserve your sanity?

• Programming for Digital frames

  - by spartan2417

  A project has recently come to my attention but i have no idea where to start or even if its possible. The idea revolves around programming a clock that is displayed inside a digital photo frame. The user would then be able to put different pictures corresponding to different times inside a usb pen for example, which would load as soon as you put the usb in. The project itself would be a really neat project - if it was just on a computer. I have no idea if what im talking about it even possible on a digital photo frame and if it is what language? Anyone who has any input at all would be great. My current idea is to maybe have a small device at the back, SSD, that runs the program through a screen, completely by passing standard digital photo frames, again though i dont know how to begin with this. And yes ive tried google (although it helps to know what to google).

• Step by step instructions to make dos "see" and "access" usb hard drives

  - by Gireesh Venkateswaran

  I am stuck with an USB external hard drive (Maxtor 1 Touch) 750GB that crashed. I have photos and home movies (my son's birth, first birthday etc) that are very important to me. I am given to understand that Spinrite is a very good tool to use, but It does not come "with out of the box" capabilities to access USB drives. If I open the case to get the HDD out from my External HDD, I would compromise the warrenty and I would not be able to exchange the Drive. I have done a bit of research and have the drivers that could help. But the bit I am missing is, How to put it all together. I would really appreciate it if some one can give me step by step instruction where I can create a dos boot cd that can load the drivers and assign a drive letter to it so that I can make Dos "See" the external hard drive. I have a Toshiba satellite laptop that runs Windows XP (Home). It does not have a floppy drive. I will be greatful to your help in the regard.

• Fix hibernate on Thinkpad X60 with 12.04 Precise Pangolin

  - by ddaa

  I own a ThinkPad X60, hibernate used to work on 10.04 Lucid Lynx, but no longer works correctly on 12.04. I am aware of how to enable hibernate in Power Manager. The problem here is, in the default configuration, pm-hibernate works, but the system fails to resume correctly. There is no video glitch, black screen or other. The resume process just freezes on the Ubuntu splash boot after a few seconds of disk activity. Is there a way to fix the system configuration so hibernates works again?

• Installing linux on OCZ RevoDrive3 x2

  - by user2101712

  First of all, here is the configuration of my computer: Motherboard: Asus H87Plus RAM: Corsair Vengeance 32GB Processor: Intel i7 4770 Drive: OCZ RevoDrive 3 x2 (240 GB) (OCZ Revodrive3 is a PCIe module) I am trying to install the latest version of Ubuntu Desktop (13.10). The problem is that in the UEFI (bios) the drive shows up as a 240 GB drive, but in the Ubuntu installer it shows up as two 120 GB drives. If I install Ubuntu in any of these two drives, it never boots. The screen flickers a few times and comes back to the UEFI menu. I have tried reading up and have come across information that the drive has a "fakeraid", and the solution is to use dmraid. However, when I give the following commands in the terminal (from live CD): # modprobe dm_mod # dmraid -ay it says: no raid disks. And the following command: # ls -la /dev/mapper/ just shows /dev/mapper/control How can I install Ubuntu on my computer? what is the correct method?

• GRUB not showing /dev/sda2 is Windows 7 Loader

  - by Ricardo

  A few days ago I accidentally deleted Ubuntu partition using GParted. I thought Windows 7 would start normally, but I got a "grub-rescue" screen instead. Then, I recreated a partition for Ubuntu (/dev/sda6) and reinstalled it. Ubuntu starts properly now; but GRUB shows me /dev/sda2 is Windows Recovery System (WRS), what is false, since /dev/sda1 is WRS and /dev/sda2 is Windows 7 Loader. I booted using Windows 7 disk and tried to correct this problem automatically and by bootrec.exe /fixboot and /fixmbr, and nothing is able to fix my problem. Yet, Windows (disk) says there is no OS in my computer. What should I do? Will I have to erase my hard disk to get Windows 7 back?

• Gnome 3 freezes when switching workspaces

  - by Bill Cheatham

  I have found an odd problem with Gnome 3 on Ubuntu recently. Under certain circumstances, when switching between two workspaces the whole desktop and user interface will 'freeze' for anything up to 2 minutes; during this time I cannot click anything or interact using the keyboard. Often, the screen will show a 'half-completed' animation of the workspace swapper. This is on Ubuntu 12.04.1 running on a 2-year old Macbook Pro, and it only seems to occur when using an external monitor. This does not seem to be a processor or memory issue, and does not occur every time I switch workspaces. Is this a known problem? What can I do in the short or long term to fix it?

• XRDP crashes when using xfce desktop

  - by user291721

  I've been struggling with this for a few days. Currently using Ubuntu 14.04. I started out trying to use VNC and could connect but only received a black and white checkered screen when connecting using tightvnc from my windows machine. Seems that applications seem to have issues interpreting the gnome graphics. I then tried XRDP and received the same issue but was able to find enough information to get by this issue. After creating a .xsession file and setting the desktop to spawn an xfce4-session I was able to connect and the desktop displays, at least for a few seconds. After a couple seconds rdp crashes and I'm unable to connect again until I restart the xrdp service. Any help would be appreciated. Thanks
