  • How can I get started using TDD to code some simple functionality?

    - by Gabriel
    I basically have the gist of TDD. I'm sold that it's useful and I've got a reasonable command of the MSTEST framework. However, to date I have not been able to graduate to using it as a primary development method. Mostly, I use it as a surrogate for writing console apps as test drivers (my traditional approach). The most useful thing about it for me is the way it absorbs the role of regression testing. I have not yet built anything yet that specifically isolates various testable behaviors, which is another big part of the picture I know. So this question is to ask for pointers on what the first test(s) I might write for the following development task: I want to produce code that encapsulates task execution in the fashion of producer/consumer. I stopped and decided to write this question after I wrote this code (wondering if I could actually use TDD for real this time) Code: interface ITask { Guid TaskId { get; } bool IsComplete { get; } bool IsFailed { get; } bool IsRunning { get; } } interface ITaskContainer { Guid AddTask(ICommand action); } interface ICommand { string CommandName { get; } Dictionary<string, object> Parameters { get; } void Execute(); }

  • USB blocks suspend on a Gigabyte GA-890GPA-UD3H with ATI SB700/SB800

    - by poolie
    Following on from question 12397, I'd still like to get suspend working on my Phenom II X6 / GA-890GPA desktop machine running current Maverick. When I run pmi action suspend the machine doesn't crash, but it also doesn't suspend. The kernel logs show: PM: Syncing filesystems ... done. PM: Preparing system for mem sleep Freezing user space processes ... (elapsed 0.02 seconds) done. Freezing remaining freezable tasks ... (elapsed 0.01 seconds) done. PM: Entering mem sleep Suspending console(s) (use no_console_suspend to debug) pm_op(): usb_dev_suspend+0x0/0x20 returns -2 PM: Device usb8 failed to suspend async: error -2 PM: Some devices failed to suspend PM: resume of devices complete after 0.430 msecs PM: resume devices took 0.000 seconds PM: Finishing wakeup. Restarting tasks ... done. PM: Syncing filesystems ... I've tried disconnecting all the USB devices, and then connecting in to run pmi over ssh, and I get the same failure. With everything unplugged, I see the following usb devices: Bus 007 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 006 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 004 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub Bus 003 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub and lspci shows the physical devices are: 00:12.0 USB Controller: ATI Technologies Inc SB700/SB800 USB OHCI0 Controller 00:12.2 USB Controller: ATI Technologies Inc SB700/SB800 USB EHCI Controller 00:13.0 USB Controller: ATI Technologies Inc SB700/SB800 USB OHCI0 Controller 00:13.2 USB Controller: ATI Technologies Inc SB700/SB800 USB EHCI Controller 00:14.5 USB Controller: ATI Technologies Inc SB700/SB800 USB OHCI2 Controller 00:16.0 USB Controller: ATI Technologies Inc SB700/SB800 USB OHCI0 Controller 00:16.2 USB Controller: ATI Technologies Inc SB700/SB800 USB EHCI Controller 02:00.0 USB Controller: NEC Corporation uPD720200 USB 3.0 Host Controller (rev 03) Booting with no_console_suspend makes no difference.

  • Ubuntu server 11.04 recognize only 1 core instead of 4

  • Acceptable placement of the composition root using dependency injection and inversion of control containers

    - by Lumirris
    I've read in several sources including Mark Seemann's 'Ploeh' blog about how the appropriate placement of the composition root of an IoC container is as close as possible to the entry point of an application. In the .NET world, these applications seem to be commonly thought of as Web projects, WPF projects, console applications, things with a typical UI (read: not library projects). Is it really going against this sage advice to place the composition root at the entry point of a library project, when it represents the logical entry point of a group of library projects, and the client of a project group such as this is someone else's work, whose author can't or won't add the composition root to their project (a UI project or yet another library project, even)? I'm familiar with Ninject as an IoC container implementation, but I imagine many others work the same way in that they can scan for a module containing all the necessary binding configurations. This means I could put a binding module in its own library project to compile with my main library project's output, and if the client wanted to change the configuration (an unlikely scenario in my case), they could drop in a replacement dll to replace the library with the binding module. This seems to avoid the most common clients having to deal with dependency injection and composition roots at all, and would make for the cleanest API for the library project group. Yet this seems to fly in the face of conventional wisdom on the issue. Is it just that most of the advice out there makes the assumption that the developer has some coordination with the development of the UI project(s) as well, rather than my case, in which I'm just developing libraries for others to use?

  • Kernel panic on reboot after failed logical volume resize

    - by Derek
    I attempted to do a logical volume resize yesterday using the follwoing commands $sudo pvdisplay "/dev/sda8" is a new physical volume of "113.11 GiB" --- NEW Physical volume --- PV Name /dev/sda8 VG Name PV Size 113.11 GiB Allocatable NO PE Size 0 Total PE 0 Free PE 0 Allocated PE 0 PV UUID jwyO1o-b2ap-CW51-kx7O-kf26-arim-SM8V6m $sudo vgextend vg /dev/sda8 sudo vgdisplay vg --- Volume group --- VG Name vg System ID Format lvm2 Metadata Areas 2 Metadata Sequence No 9 VG Access read/write VG Status resizable MAX LV 0 Cur LV 5 Open LV 5 Max PV 0 Cur PV 2 Act PV 2 VG Size 131.74 GiB PE Size 4.00 MiB Total PE 33725 Alloc PE / Size 4769 / 18.63 GiB Free PE / Size 28956 / 113.11 GiB VG UUID AhusW2-pzFv-3W32-mpv2-s5VG-FN7S-kVSadx $sudo lvresize -L +20GB /dev/mapper/vg-var So as you can see, it looks like adding the physical volume to the vg worked, because i see free space available there. When I typed the lvresize command, it never returned. I let this run overnight in the background, but this morning I still couldnt successfully do a "pvdisplay" or "lvdisplay" because I think it was waiting on a lock or something, so the command never returned. When i went to log onto the server's console, I saw a bunch of messages like: rcu_sched_state detected stall on cpu 2 Now when I boot, I get a kernel panic error, and a message about not being able to mount /mapper/vg-root cannot open root device "mapper/vg-root" or unknown_block(0,0) Kernel Panic -not syncing: VFS: Unable to mount root file system on unknown_block(0,0) What should I do to get my system back up and running? Did I attempt to do the logical volume resize correctly? Thanks

  • Hybrid Graphics on Ubuntu 12.04 switching to discrete

    - by cfstras
    I have a Sony Vaio VPCCB-27FX with hybrid graphics. Using vgaswitcheroo enables me to switch my discrete card off to save power. Now when i want to switch to the discrete card for performance, my system freezes. I already tried logging out and killing x with service lightdm stop, but still, it freezes as soon as I echo DIS > switch. typing blindly, echo IGD > switch returns me to my console where it reads [ 179.555171] i915: switched off, but it seems the discrete card never gets switched on... running echo DDIS > switch gives me the following: [540....] [drm:atop_op_jump] *ERROR* atombios stuck in loop for more than 5secs aborting [540....] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing CEE2 (len 62, WS 0, PS 0) @ 0xCEFE [540....] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing BBF6 (len 1036, WS 4, PS 0) @ 0xBCF3 [540....] [drm:atom_execute_table_locked] *ERROR* atombios stuck executing BB8C (len 76, WS 0, PS 0) @ 0xBB94 [541....] [drm:r600_RING_TEST] *ERROR* radeon: ring test failed (scratch(0x8504)=0xFFFFFFFF) [541....] [drm:evergreen_resume] *ERROR* evergreen startup failed on resume after that, the atombios part repeats a few times. also, the terminal locks up again and sysrq+REISUB is my only rescue.

  • Groovy/Grails course content

    - by Don
    Hi, Some Java developers have asked if I could give them a 2-day primer on Grails development. I'm assuming they're familiar with: Java language and libraries Java web development, e.g. Servlets, JSPs Spring Hibernate Client-side development, CSS, HTML, JavaScript I'm further assuming they have no experience with Groovy or Grails. AFAIK, the app that they'll be building is a new project, so there's no need to cover topics like using GORM with a legacy database. I'm trying to decide how I should structure the course, e.g. what topics to cover and how much time to spend on each. I reckon about 1/2 - 3/4 days on Groovy and the rest of the time on Grails would be adequate. I'll probably use the Groovy console to demonstrate the Groovy language concepts and a simple Grails app for explaining the conventions and structure of a Grails project. If anyone has a list of Groovy/Grails topics that I should cover, or even an outline of a similar course that they've given/taken, I'd be very grateful. Naturally, I will credit for any resources that I use during the course.

  • Recovering data from /

    - by Abhijit Gavas
    I accidentally installed Ubuntu to one of my data drives from Windows. The drive was a NTFS drive and contained about 80 GB of important data. The size of the drive is 110 GB. Its new file system is ext4. In an attempt to recover the data, I downloaded foremost and tried the following commands: foremost -i / -o /media/281C8DB01C8D7998/Recovery/ -T -v foremost -i /dev/sda7 -o /media/281C8DB01C8D7998/Recovery/ -T -v (sda7 is the drive in question.) It appears that with either command, foremost gets stuck reading some file. Here is the console output: abhi@abi-PC:/dev$ foremost -i /dev/sda7 -o /media/281C8DB01C8D7998/Recovery/ -T -v Foremost version 1.5.7 by Jesse Kornblum, Kris Kendall, and Nick Mikus Audit File Foremost started at Fri Sep 28 20:58:00 2012 Invocation: foremost -i /dev/sda7 -o /media/281C8DB01C8D7998/Recovery/ -T -v Output directory: /media/281C8DB01C8D7998/Recovery_Fri_Sep_28_20_58_00_2012 Configuration file: /etc/foremost.conf Processing: stdin |------------------------------------------------------------------ File: stdin Start: Fri Sep 28 20:58:00 2012 Length: Unknown Num Name (bs=512) Size File Offset Comment Killed As you can see I have to kill it from system monitor. This approach does not seem to be working. What else could I try to recover the files? Please help. The files are very important and I will be devastated if I cannot recover them.

  • Ubuntu 12.04LTS stuck at login mouse and keyboard not responding

    - by user169954
    I have Ubuntu 12.04LTS installed on a dual-booted machine (i5 dual core 8G ram) and it's been working fine, but today for some reason when I logged out and tried to log back in it is stuck at the login page, i.e. the mouse and the keyboard are not responding. The mouse is stuck at the top left corner of my screen, and I can do nothing but to turn the machine off. (I have been using logitech wireless mouse and keyboard.) I can not access the virtual console (Alt-F1 or Cntrl-Alt-F1) either! Here is what I have tried so far: Verified it is not a H/W problem since the mouse and keyboard work fine with windows7 Booted with ubuntu installation dvd and ran trial mode and mouse and keyboard worked fine. Tried bypassing the login screen by booting into recovery mode and editing tty1.conf, but to no avail. I moved .Xauthority .profile and .bashrc from my $HOME to another location so my login would proceed completely by system defaults. But this did not help From recovery mode commandline used to dpkg-reconfigure to switch between gdm and lightgdm. This did not help either. By the way, when in recovery mode as root from command line I mount the filesystem, all apps work fine. Python is Ok, octave is ok, vi is ok etc. I have a feeling if I could only bypass the login screen, and automatically get into the desktop, I will be ok. But I haven't been able to accomplish this either. I desperately need help please. Thank you in advance. Update: So I tried to switch to lightdm by dpkg-configure lightdm. This at least brings me up to the classical linux commandline login prompt but without a gui. Should I install startx? Should I install ubuntu-desktop?

  • Restoring GRUB2 on Software RAID 0 using LiveCD after Windows 7 wiped it

    - by unknownthreat
    I have installed Ubuntu 10.10 on my system. However, I need to install Windows 7 back, and I expect that it would alter GRUB and it did. Right now, my partition on my Software RAID 0 looks like this: nvidia_acajefec1 is Ubuntu 10.10 and nvidia_acajefec3 is Windows 7. I've been following some guides around and I am always stuck at GRUB not able to detect the usual RAID content. I've tried running: sudo grub > root (hd0,0) GRUB complains it couldn't find my hard disk. So I tried: find (hd0,0) And it complains that it couldn't find anything. So I tried: find /boot/grub/stage1 It said "file not found". Here's the text from the console: ubuntu@ubuntu:~$ grub Probing devices to guess BIOS drives. This may take a long time. [ Minimal BASH-like line editing is supported. For the first word, TAB lists possible command completions. Anywhere else TAB lists the possible completions of a device/filename. ] grub> root (hd0,0) root (hd0,0) Error 21: Selected disk does not exist grub> find /boot/grub/stage1 find /boot/grub/stage1 Error 15: File not found Fortunately, I got one person suggesting that what I've been trying to do is for GRUB Legacy, not GRUB2. So I went to the suggested website, ** (http://grub.enbug.org/Grub2LiveCdInstallGuide) **try to look around, and try: ubuntu@ubuntu:~$ sudo fdisk -l Unable to seek on /dev/sda This is just the step 2 of the instruction in the http://grub.enbug.org/Grub2LiveCdInstallGuide and I cannot proceed because it cannot seek /dev/sda. However, ubuntu@ubuntu:~$ sudo dmraid -r /dev/sdb: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0 /dev/sda: nvidia, "nvidia_acajefec", stripe, ok, 488397166 sectors, data@ 0 So what now? Do you have an idea for how to make fdisk see my RAID array on live cd (Ubuntu 10.10)? Honestly, I am lost, very lost in trying to restore GRUB2 on this software RAID 0 system right now.

  • ImageResizer - AzureReader2 with Azure SDK 2.2

    - by Chris Skardon
    Originally posted on: http://geekswithblogs.net/cskardon/archive/2013/10/29/imageresizer---azurereader2-with-azure-sdk-2.2.aspxSo Azure SDK 2.2 came out recently, which means I can open my azure projects in VS 2013 (yay), so I decided to do an upgrade of my MVC4 project to MVC5, I followed this link on how to do the upgrade, and generally things went ok. I fire up my app, and run into a ‘binding’ issue, that AzureReader2 was trying to use Microsoft.WindowsAzure.Storage, Version=2.1.0.0 but alas, it couldn’t find it. I am not the only one (see stackoverflow), and one solution is to run ‘Add-BindingRedirect’ from the Package Manager Console, but that didn’t solve the problem for me, as it didn’t pick up on the Azure stuff, so I resorted to adding the redirect manually. So, in short, to get AzureReader2 to work with Azure SDK 2.2, you need to add the following to your web.config: <runtime> <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1"> <!-- Other bindings here! --> <dependentAssembly> <assemblyIdentity name="Microsoft.WindowsAzure.Storage" publicKeyToken="31bf3856ad364e35" culture="neutral"/> <bindingRedirect oldVersion="0.0.0.0-2.1.0.3" newVersion="2.1.0.3"/> </dependentAssembly> </assemblyBinding>

  • Cannot activate num pad at all

    - by ubuntico
    I have two accounts on the same machine. Num pad on one account it working normally e.g. I can turn it ON/OFF via NumLock button. The num pad on the other account on this machine stopped working. I cannot turn it on and the buttons work as the NumLock is turned off. This happened without me touching any setting or all. It just happened and now I cannot turn them on no matter what I try. I tried via console command numlockx on - did not help. Tried via UI setting - did not help either. Updated the system from 11.10 to 12.04, did not help either. I really do not know what to do except I make a clean reinstallation of the system which would take 2 days away from me. It's obviously the problem in this account only, as num pad works in the other account. Anyone with a good suggestion?

  • Using Computer Management (MMC) with the Solaris CIFS Service (August 25, 2009)

    - by user12612012
    One of our goals for the Solaris CIFS Service is to provide seamless Windows interoperability: not just to deliver ubiquitous, multi-protocol file sharing, which is obviously a major part of this project, but to support Windows services at a fundamental level.  It's an ongoing mission and our latest update includes support for Windows remote management. Remote management is extremely important to Windows administrators and one of the mainstay tools is Computer Management. Computer Management is a Windows administration application, actually a collection of Microsoft Management Console (MMC) tools, that can be used to configure, monitor and manage local and remote services and resources.  The MMC is an extensible framework of registered components, known as snap-ins, which allows Computer Management to provide comprehensive management features for both the local system and remote systems on the network. Supported Computer Management features include: Share ManagementSupport for share management is relatively complete.  You can create, delete, list and configure shares.  It's not yet possible to change the maximum allowed or number of users properties but other properties, including the Share Permissions, can be managed via the MMC. Users, Groups and ConnectionsYou can view local SMB users and groups, monitor user connections and see the list of open files. If necessary, you can also disconnect users and/or close files. ServicesYou can view the SMF services running on an OpenSolaris system.  This is a read-only view - we don't support service management (the ability to start or stop) SMF services from Computer Management (yet). To ensure that only the appropriate users have access to administrative operations there are some access restrictions on these remote management features. Regular users can: List shares Only members of the Administrators or Power Users groups can: Manage shares List connections Only members of the Administrators group can: List open files and close files Disconnect users View SMF services View the EventLog Here's a screenshot when I was using Computer Management and Server Manager (another Windows remote management application) on Windows XP to view some open files on an OpenSolaris system to prepare a slide presentation on MMC support.

  • Take care to unhook Anonymous Delegates

    - by David Vallens
    Anonymous delegates are great, they elimiante the need for lots of small classes that just pass values around, however care needs to be taken when using them, as they are not automatically unhooked when the function you created them in returns. In fact after it returns there is no way to unhook them. Consider the following code.   using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Diagnostics; namespace ConsoleApplication1 { class Program { static void Main(string[] args) { SimpleEventSource t = new SimpleEventSource(); t.FireEvent(); FunctionWithAnonymousDelegate(t); t.FireEvent(); } private static void FunctionWithAnonymousDelegate(SimpleEventSource t) { t.MyEvent += delegate(object sender, EventArgs args) { Debug.WriteLine("Anonymous delegate called"); }; t.FireEvent(); } } public class SimpleEventSource { public event EventHandler MyEvent; public void FireEvent() { if (MyEvent == null) { Debug.WriteLine("Attempting to fire event - but no ones listening"); } else { Debug.WriteLine("Firing event"); MyEvent(this, EventArgs.Empty); } } } } If you expected the anonymous delegates do die with the function that created it then you would expect the output Attempting to fire event - but no ones listeningFiring eventAnonymous delegate calledAttempting to fire event - but no ones listening However what you actually get is Attempting to fire event - but no ones listeningFiring eventAnonymous delegate calledFiring eventAnonymous delegate called In my example the issue is just slowing things down, but if your delegate modifies objects, then you could end up with dificult to diagnose bugs. A solution to this problem is to unhook the delegate within the function var myDelegate = delegate(){Console.WriteLine("I did it!");}; MyEvent += myDelegate; // .... later MyEvent -= myDelegate;

  • Site failing randomly - could it be Cloudflare or something weird in the JS?

    - by James
    I've been working on a simple site that uses javascript to fade through some fullscreen background images as well as some other simple animations. I've tested the site on Chrome, Safari, FF and Opera on OSX, IE8+ on Win7 and Chrome & FF on Ubuntu and everything looks as I'd expect it to. However, I've had reports of the site failing to load (stops at the stage where the background fades up) on Safari and Chrome on OSX and Win. I can't replicate this on any setup so I'm finding it impossible to troubleshoot. Google's instant preview shows the site fine as does most of the options at browsershots.org so I'm really scratching my head. I'm running the site's traffic through Cloudflare and I'm wondering whether anyone can see (or knows from other sites) why Cloudflare might be mangling the JS or causing a problem somehow (I don't get any errors in the JS error console). Of course, if you can replicate the problem on your machine and can suggest an area to look at that would be amazing but I'm hoping that, like me, you don't see any problem with the site! Here's the site: http://www.bighornrevelstoke.com Thanks, James

  • to upgrade / install wine 1.55 on ubuntu 12.04 or any distro

    - by user67550
    Wine news and installation 1.5.5 on ubuntu Now available in PPA wine version 1.55, an application that lets Windows programs run on any distribution with GNU / Linux. Wine (recursive acronym in English for Wine Is Not an Emulator, which means "Wine Is Not an Emulator") is a reimplementation of the application programming interface for Win16 and Win32 operating systems based on Unix. Allows execution of programs designed for MS-DOS and Microsoft Windows Version 3.11, 95, 98, Me, NT, 2000, XP, Vista and 7 The name was originally an acronym Wine Windows Emulator. This meaning was later changed to the current recursive acronym. These are some of the highlights: Support for the installation of Mono as a complement to wine in the package. The dither pattern brushes in the motor DIB. Support to install the runtime. NET 4.0. D3dx9 DDS files supported. Several bug fixes. To install on Ubuntu just open the console and type: sudo add-apt-repository ppa: ubuntu-wine/ppa sudo apt-get update sudo apt-get install wine1.5 Source: ubuntutips If you enjoyed this post share it with your friends, thanks

  • Getting the PC speaker to beep

    - by broiyan
    There has been much written on getting the beep sound from Ubuntu releases over the years. Example: fixing the beep My needs are slightly different in that I do not want to ensure sound card beeps are functioning. Instead, I want PC speaker beeps, the kind produced by the original built-in speaker because I believe they will produce less CPU load. I have confirmed that my computer has the PC speaker by unplugging the external speakers and shutting down Ubuntu. At some point in the shutdown and restart process a beep is heard even though the external speakers have no power. I have tried the following: In /etc/modprobe.d/blacklist.conf, turn these lines into comments: #blacklist snd_pcsp #blacklist pcspkr In .bashrc /usr/bin/xset b on /usr/bin/xset b 100 Enable in the gnome terminal: Edit Profile Prefs General Terminal Bell Ensure no "mute" selections in: System Prefs Sound various tabs (uncheck them all). Select "Enable window and button sounds" in: System Prefs Sound Sound Effects In gconf-editor desktop gnome sound, select the three sound check boxes. In gconf-editor apps metacity general select the audible bell check box. Still I get no PC speaker beeps when I send code 7 to the console via my Java program or use echo -e '\a' on the bash command line. What else should I try? Update Since my goal is to minimize load on the CPU, here is a comparison of elapsed times. Each test is for 100,000 iterations. Each variant was performed three times so three results are presented for each. printwriter.format("%c", 7); // 1.3 seconds, 1.5 seconds, 1.5 seconds Toolkit.getDefaultToolkit().beep(); // 0.8 seconds, 0.3 seconds, 0.5 seconds try { Runtime.getRuntime().exec("beep"); } catch (IOException e) { } // 10.3 seconds, 16.3 seconds, 11.4 seconds These runs were done inside Eclipse so multiply by some value less than 1 for standalone execution. Unfortunately, Toolkit's beep is silent on my computer and so is code 7. The beep utility works but has the most cost.

  • Speaking in Sweden in April

    - by Fabrice Marguerie
    As this is my first post in 2011, I wish you all the best for this new year. I don't know for you, but it will be a year of changes for me. I'll tell you more about that when the time comes. For the time being, I just wanted to announce my next speaking engagement: I'll be presenting at SDC2011, the Scandinavian Developer Conference. This event will take place on April 4 and 5 in Göteborg, Sweden. My session will be based on my article about memory leaks: How to detect and avoid memory and resources leaks in .NET applicationsDuring this session we will analyze the most common leak sources in .NET applications and we will see how to detect them in practice. We will demonstrate with live examples several tools that can help you to troubleshoot your applications. The goal of this session is to help you fix and avoid leaks in your .NET applications, whether they are built with Windows Forms, WPF, Silverlight, ASP.NET, or as console or Windows services. You will also get advices on how to improve your applications so they become less greedy. I hope to see you there if you're around in April :-)

  • Could not load file or assembly 'System.Data.SQLite' or one of its dependencies. An attempt was made to load a program with an incorrect format.

    - by Om Talsania
    Problem Description: Could not load file or assembly 'System.Data.SQLite' or one of its dependencies. An attempt was made to load a program with an incorrect format. Likely to be reproduced when: You will usually encounter this problem when you have downloaded a sample application that is a 32-bit application targeted for ASP.NET 2.0 or 3.5, and you have IIS7 on a 64-bit OS running .NET 4.0, because the default setting for running 32-bit application on IIS7 with 64-bit OS is false. Resolution: 1. Go to IIS Management Console Start -> Administration Tools -> Internet Information Services (IIS) Manager 2. Expand your server in the left pane and go to Application Pools 3. Right click to select ‘Add Application Pool’  4. Create anew AppPool. I have named it ASP.NET v2.0 AppPool (32-bit) and selected .NET Framework v2.0.50727 because I intend to run my ASP.NET 3.5 application on it. 5. Now right click the newly created AppPool and select Advanced Settings 6. Change the property “Enable 32-Bit Applications” from False to True  7. Now select your actual web application from the left panel. Right click the web application, and go to Manage Application -> Advanced Settings  8. Change the Property “Application Pool” to your newly created AppPool.  And… the error is gone…

  • Configuring Team Foundation Server Basic on Home Server.

    - by Enrique Lima
    For the installation I selected only the Team Foundation Server role. Then, I opened the Team Foundation Server Administration Console (which I think is a great addition and improvement over the way TFS was configured in the past) to proceed with the configuration of the pieces. Once I selected the Configure Installed Features, the Configuration Center opened up. Now, the choices … In my implementation here I just want to take advantage of Source Control primarily.  I want to be able to store my code and projects.  So, Basic it is! So, the Basic Configuration Wizard opens up.  Now the options to configure are very limited, but we have to provide details for the SQL Server Instance. And now, to select Install SQL Server express.  If you want to take advantage of another system in your environment to host your database, well you could Use an existing SQL Server Instance. Once it has the details it needs, you get a Summary view to confirm your choices. Once, you click next or verify, it runs readiness checks on your system to make sure the installation will have a successful pass.  And we love GREEN! Now, since got the green flag, our next stop is to let the wizard do its magic, click on Configure.  And once again, we love GREEN! We click Next, and … We like a big Green Success sign … We close the Configuration Center … First results … Web Access …  Nothing to show … but we are there! And all this running from a Microsoft Home Server installation.

  • Creating an update method in a different class

    - by Sweta Dwivedi
    I have created a class called 3D model which will animate my 3D model by changing the model position according to the values based in a .txt file through a list... Since i'm using a foreach loop to read the point values when it reaches the end of the file.. XNA throws an out of bounds exception .. (which is obvious) but if i add the same code in my Game.cs update(gameTime) method.. then i dont have this problem..Any idea how to make my 3D model update work same as the update in game.cs .. Here is the code for some idea: public void patterns(GameTime gameTime) { motion_z = new List<Point3D>(); if (pattern == 1) { f = "E:/Motion_Track-output/Output1.txt"; } if (pattern == 2) { f = "E:/Motion_Track-output/cruse.txt"; } // TODO: Add your update logic here using (StreamReader r = new StreamReader(f)) { string line; //Viewport view = graphics.GraphicsDevice.Viewport; int maxWidth = view.Width; int maxHeight = view.Height; while ((line = r.ReadLine()) != null) { string[] temp = line.Split(','); int x = (int)Math.Floor(((float.Parse(temp[0]) * 0.5f) + 0.5f) * maxWidth); int y = (int)Math.Floor(((float.Parse(temp[1]) * -0.5f) + 0.5f) * maxHeight); int z = (int)Math.Floor(((float.Parse(temp[2]) / 4 * 20000))); motion_z.Add(new Point3D(x, y, z)); } modelPosition.X = (float)(motion_z[i].X); modelPosition.Y = (float)(motion_z[i].Y); modelPosition.Z = (float)(motion_z[i].Z); i++; } //Console.WriteLine("modelposX:" + modelPosition.X + "," + "motionzX:" + motion_z[i].X); }

  • Pandaboard crash on startup or freeze after minutes

    - by Meach
    I just received my Pandaboard ES (rev B) and I am having trouble after installing ubuntu-omap4-addons. Once I copied the image ubuntu-12.04-preinstalled-desktop-armhf+omap4.img on my sd card and boot the pandaboard with it, I run the following commands: sudo add-apt-repository ppa:tiomap-dev/release sudo apt-get update sudo apt-get dist-upgrade sudo apt-get install ubuntu-omap4-extras At the end of the installation of ubuntu-omap4-extras, Ubuntu tells me that a problem occurs when the console displays: ldconfig deferred processing now taking place Clicking on "report the problem" tell me that the problem concerns pvr-omap4-dkms. I read somewhere that this can happen and it is better to reinstall pvr-omap4-dkms. Which I am doing by running: sudo apt-get install --reinstall pvr-omap4-dkms I reboot. Then the board has sometimes difficulties to start Ubuntu: it freezes during the loading page, only action I can do is unplugging the board to start it again. Some other times, Ubuntu load successfully but then freeze at another random time, in the range 20 - 40 minutes. I searched on internet for similar bug and found this: https://bugs.launchpad.net/ubuntu/+source/linux-ti-omap4/+bug/971091 So I typed this in: update-rc.d ondemand disable apt-get -y install cpufrequtils echo 'ENABLE="true" GOVERNOR="performance" MAX_SPEED="0" MIN_SPEED="0"' > /etc/default/cpufrequtils cpufreq-set -r -g performance reboot But it doesn't seems to fix the bug. Another detail: on startup, before the loading screen of Ubuntu (when there is the two penguins displayed :)), it shows this: [0.297271] CPU1: Unknown IPI message 0x1 [0.308990] omap_hwmod: mcpdm: _wait_target_ready error: -16 [0.354705] omap_mux_get_by_name: Could not find signal uart1_cts.uart1_cts [0.354766] omap_hwmod_mux_init: Could not allocate device mux entry [2.107086] thermal_get_slope:Getting slope is not supported for domain gpu [2.107116] thermal_get_offset:Getting offset is not supported for domain gpu [2.107299] stm_fw: vendor driver stm_ti1.0 registered [8.725555] OMAPRPC: Registration of OMAPRPC rpmsg service returned 0! debug=0 Any idea what can be wrong? I am not that good with Ubuntu so any help will be appreciated. Cheers! Meach

  • JBox2D applyLinearImpulse doesn't work

    - by Romeo
    So i have this line of code: if(input.isKeyDown(Input.KEY_W)&&canJump()) { body.applyLinearImpulse(new Vec2(0, 30), cam.screenToWorld(body.getPosition())); System.out.println("I can jump!"); } My problem is that the console display I can jump! but the body doesn't do that. Can you explain to me if i do something wrong? Some more code. This function creates my 'hero' the one supposed to jump. private Body setDynamic(float width, float height, float x, float y) { PolygonShape shape = new PolygonShape(); shape.setAsBox(width/2, height/2); BodyDef bd = new BodyDef(); bd.allowSleep = true; bd.position = new Vec2(cam.screenToWorld(new Vec2(x + width / 2, y + height / 2))); bd.type = BodyType.DYNAMIC; bd.userData = new BodyInfo(width, height); Body body = world.createBody(bd); body.createFixture(shape, 10); return body; } And this is the main update loop: if(input.isKeyDown(Input.KEY_A)) { body.setLinearVelocity(new Vec2(-10*delta, body.getLinearVelocity().y)); } else if (input.isKeyDown(Input.KEY_D)) { body.setLinearVelocity(new Vec2(10*delta, body.getLinearVelocity().y)); } else { body.setLinearVelocity(new Vec2(0, body.getLinearVelocity().y)); } if(input.isKeyDown(Input.KEY_W)&&canJump()) { body.applyLinearImpulse(new Vec2(0, 30), body.getPosition()); System.out.println("I can jump!"); } world.step(delta * 0.001f, 10, 5); }
