• Member Status: Inquorate in RHEL 5.6

  - by Eugene S

  I've encountered a strange issue. I had to change the time on my Linux RHEL cluster system. I've done it using the following command from the root user: date +%T -s "10:13:13" After doing this, some message appeared relating to <emerg> #1: Quorum Dissolved (however I didn't capture the message completely). In order to investigate the issue I looked at /var/log/messages and I've discovered these errors. Below is the output of few commands I got when tried to investigate the issue, however I don't have enough knowledge to make use of this information. [root@system1a ~]# clustat Cluster Status for system4081 @ Sun Mar 25 11:45:48 2012 Member Status: Inquorate Member Name ID Status ------ ---- ---- ------ chb_sys1a 1 Online, Local chb_sys2a 2 Offline [root@system1a ~]# cman_tool nodes Node Sts Inc Joined Name 1 M 872 2012-03-25 08:43:07 chb_sys1a 2 X 0 chb_sys2a [root@system1a ~]# qdiskd -f -d [17654] debug: Loading configuration information [17654] debug: 0 heuristics loaded [17654] debug: Quorum Daemon: 0 heuristics, 1 interval, 10 tko, 0 votes [17654] debug: Run Flags: 00000035 [17654] info: Quorum Daemon Initializing stat: Bad address [17654] crit: Initialization failed I tried to search through the internet and found out a quite similar issue here. However, for some reason I am not able to access the bug on bugzilla. The link to the bug is here

• Setup.exe called from a batch file crashes with error 0x0000006

  - by Alex

  We're going to be installing some new software on pretty much all of our computers and I'm trying to setup a GPO to do it. We're running a Windows Server 2008 R2 domain controller and all of our machines are Windows 7. The GPO calls the following script which sits on a network share on our file server. The script it self calls an executable that sits on another network share on another server. The executable will imediatelly crash with an error 0x0000006. The event log just says this: Windows cannot access the file for one of the following reasons: there is a problem with the network connection, the disk that the file is stored on, or the storage drivers installed on this computer; or the disk is missing. Windows closed the program Setup.exe because of this error. Here's the script (which is stored on \\WIN2K8R2-F-01\Remote Applications): @ECHO OFF IF DEFINED ProgramFiles(x86) ( ECHO DEBUG: 64-bit platform SET _path="C:\Program Files (x86)\Canam" ) ELSE ( ECHO DEBUG: 32-bit platform SET _path="C:\Program Files\Canam" ) IF NOT EXIST %_path% ( ECHO DEBUG: Folder does not exist PUSHD \\WIN2K8R2-PSA-01\PSA Data\Client START "" "Setup.exe" "/q" POPD ) ELSE ( ECHO DEBUG: Folder exists ) Running the script manually as administrator also results in the same error. Setting up a shortcut with the same target and parameters works perfectly. Manually calling the executable also works. Not sure if it matters, but the installer is based on dotNETInstaller. I don't know what version though. I'd appreciate any suggestions on fixing this. Thanks in advance! UPDATE I highly doubt this matters, but the network share that the script is hosted in is a shared drive, while the network share the script references for the executable is a shared folder. Also, both shares have Domain Computers listed with full access for the sharing and security tabs. And PUSHD works without wrapping the path in quotes.

• SSH connection problem - allowed from LAN but not WAN

  - by Kerem Ulutas

  I tried to setup my Arch Linux installation to be an SSH host, but here is the thing: I can ssh localhost, it fails to login via public key and asks for username and password, but still able to login. When I try ssh my_wan_ip it gives ssh_exchange_identification: Connection closed by remote host error. I've read all topics about this error and none helped me. By the way, just confirmed, it gives ssh: connect to host my_dyndns_hostname port 22: Connection refused from another machine (outside of my network, it has different wan ip). I have sshd: ALL in "hosts.allow", ALL:ALL in "hosts.deny". I am able to connect to my own pc via ssh, ping my own pc, but my ssh setup seems to be the problem, it gives that annoying error when I try to ssh from wan. /etc/ssh/ssh_config /etc/ssh/sshd_config And finally, here is the debug output for both sshd and ssh: (i ran ssh command and i took output to sshd debug after that): sshd debug ssh debug I can edit my question according to your needs. Just ask for any more information needed. BTW I have no iptables running. I have one cable dsl modem connected to a asus wl-330gE wireless access point, they both have their firewall disabled. I configured NAT so port 22 is directed to the pc I'm having this trouble. Any help appreciated, thanks..

• PHP displays blank white page even with all error reporting enabled

  - by Andy Shinn

  I am trying to debug a broken page in a Drupal application and am having a hard time getting PHP to spit anything useful out. I have the following set: error_reporting = E_ALL display_errors = On display_startup_errors = On log_errors = On error_log = /var/log/php/php_error.log I have a file showing me phpinfo() which confirms these variables are set correctly for the environment. I have increased memory_limit to 256M (which should be more than enough). Yet, the only indication I get is a status 500 code in the apache access log and a blank white page from PHP. The Apache virtual host has LogLevel set to debug and the error log only outputs: [Sat Jun 16 20:03:03 2012] [debug] mod_deflate.c(615): [client 173.8.175.217] Zlib: Compressed 0 to 2 : URL /index.php, referer: http://ec2-174-129-192-237.compute-1.amazonaws.com/admin/reports/updates [Sat Jun 16 20:03:03 2012] [error] [client 173.8.175.217] File does not exist: /var/www/favicon.ico [Sat Jun 16 20:03:03 2012] [debug] mod_deflate.c(615): [client 173.8.175.217] Zlib: Compressed 42 to 44 : URL /favicon.ico The PHP error log outputs nothing at all. kernel and syslog show nothing related to Apache or PHP. I have also tried installing suphp and checking its log just confirms the user is executing correctly: [Sat Jun 16 20:02:59 2012] [info] Executing "/var/www/index.php" as UID 1000, GID 1000 [Sat Jun 16 20:05:03 2012] [info] Executing "/var/www/index.php" as UID 1000, GID 1000 This is on Ubuntu 12.04 x86_64 with the following PHP modules: ii php5 5.3.10-1ubuntu3.1 server-side, HTML-embedded scripting language (metapackage) ii php5-cgi 5.3.10-1ubuntu3.1 server-side, HTML-embedded scripting language (CGI binary) ii php5-cli 5.3.10-1ubuntu3.1 command-line interpreter for the php5 scripting language ii php5-common 5.3.10-1ubuntu3.1 Common files for packages built from the php5 source ii php5-curl 5.3.10-1ubuntu3.1 CURL module for php5 ii php5-gd 5.3.10-1ubuntu3.1 GD module for php5 ii php5-mysql 5.3.10-1ubuntu3.1 MySQL module for php5 So, what am I missing here? Why no error reporting?

• Why isn't Apache Basic authentication working?

  - by Brad

  I just upgraded Apache from it's 2003 build, to a squeaky-clean, brand-new 2.4.1 build. All seems pretty good except for one glaring thing: In my httpd.conf file I have the following: <Directory /> AllowOverride none Options FollowSymLinks AuthType Basic AuthName "Enter Password" AuthUserFile /var/www/.htpasswd Require valid-user </Directory> This should allow only users in the specified auth file to access the server - just as it had under the older version of Apache. (Right?) However, it's not working. Requests are granted with no authentication provided. When I switch logging to LogLevel Debug, for the accesses, it says: [Sat Mar 24 21:32:00.585139 2012] [authz_core:debug] [pid 10733:tid 32771] mod_authz_core.c(783): [client 192.168.1.181:57677] AH01626: authorization result of Require all granted: granted [Sat Mar 24 21:32:00.585446 2012] [authz_core:debug] [pid 10733:tid 32771] mod_authz_core.c(783): [client 192.168.1.181:57677] AH01626: authorization result of <RequireAny>: granted I really don't know what this means - and I (to the best of my knowledge) don't have any "Require all granted" or "" statements in any of my files. Any ideas why this isn't working, or where to debug??

• SQL03070: This statement is not recognized in this context

  - by prash

  Recently I have started working with VS2010 and Fx4. There have been various challenges. We also introduced a new Database Project in our solution. And found this error. The reason for this error is: the project system expects the stored procedure as a create statement only.  The additional statements to drop if existing are not necessary within the project system.  Project deployment takes care of detecting if the sproc already exists and if it needs to be updated. To resolve this error you can simply remove the additional statements other then your create SP, Function etc. OR Exclude the file from build. Right Click on your file in Solution Explorer, Click Properties > Build Action > Not in Build

• Using Durandal to Create Single Page Apps

  - by Stephen.Walther

  A few days ago, I gave a talk on building Single Page Apps on the Microsoft Stack. In that talk, I recommended that people use Knockout, Sammy, and RequireJS to build their presentation layer and use the ASP.NET Web API to expose data from their server. After I gave the talk, several people contacted me and suggested that I investigate a new open-source JavaScript library named Durandal. Durandal stitches together Knockout, Sammy, and RequireJS to make it easier to use these technologies together. In this blog entry, I want to provide a brief walkthrough of using Durandal to create a simple Single Page App. I am going to demonstrate how you can create a simple Movies App which contains (virtual) pages for viewing a list of movies, adding new movies, and viewing movie details. The goal of this blog entry is to give you a sense of what it is like to build apps with Durandal. Installing Durandal First things first. How do you get Durandal? The GitHub project for Durandal is located here: https://github.com/BlueSpire/Durandal The Wiki — located at the GitHub project — contains all of the current documentation for Durandal. Currently, the documentation is a little sparse, but it is enough to get you started. Instead of downloading the Durandal source from GitHub, a better option for getting started with Durandal is to install one of the Durandal NuGet packages. I built the Movies App described in this blog entry by first creating a new ASP.NET MVC 4 Web Application with the Basic Template. Next, I executed the following command from the Package Manager Console: Install-Package Durandal.StarterKit As you can see from the screenshot of the Package Manager Console above, the Durandal Starter Kit package has several dependencies including: · jQuery · Knockout · Sammy · Twitter Bootstrap The Durandal Starter Kit package includes a sample Durandal application. You can get to the Starter Kit app by navigating to the Durandal controller. Unfortunately, when I first tried to run the Starter Kit app, I got an error because the Starter Kit is hard-coded to use a particular version of jQuery which is already out of date. You can fix this issue by modifying the App_Start\DurandalBundleConfig.cs file so it is jQuery version agnostic like this: bundles.Add( new ScriptBundle("~/scripts/vendor") .Include("~/Scripts/jquery-{version}.js") .Include("~/Scripts/knockout-{version}.js") .Include("~/Scripts/sammy-{version}.js") // .Include("~/Scripts/jquery-1.9.0.min.js") // .Include("~/Scripts/knockout-2.2.1.js") // .Include("~/Scripts/sammy-0.7.4.min.js") .Include("~/Scripts/bootstrap.min.js") ); The recommendation is that you create a Durandal app in a folder off your project root named App. The App folder in the Starter Kit contains the following subfolders and files: · durandal – This folder contains the actual durandal JavaScript library. · viewmodels – This folder contains all of your application’s view models. · views – This folder contains all of your application’s views. · main.js — This file contains all of the JavaScript startup code for your app including the client-side routing configuration. · main-built.js – This file contains an optimized version of your application. You need to build this file by using the RequireJS optimizer (unfortunately, before you can run the optimizer, you must first install NodeJS). For the purpose of this blog entry, I wanted to start from scratch when building the Movies app, so I deleted all of these files and folders except for the durandal folder which contains the durandal library. Creating the ASP.NET MVC Controller and View A Durandal app is built using a single server-side ASP.NET MVC controller and ASP.NET MVC view. A Durandal app is a Single Page App. When you navigate between pages, you are not navigating to new pages on the server. Instead, you are loading new virtual pages into the one-and-only-one server-side view. For the Movies app, I created the following ASP.NET MVC Home controller: public class HomeController : Controller { public ActionResult Index() { return View(); } } There is nothing special about the Home controller – it is as basic as it gets. Next, I created the following server-side ASP.NET view. This is the one-and-only server-side view used by the Movies app: @{ Layout = null; } <!DOCTYPE html> <html> <head> <title>Index</title> </head> <body> <div id="applicationHost"> Loading app.... </div> @Scripts.Render("~/scripts/vendor") <script type="text/javascript" src="~/App/durandal/amd/require.js" data-main="/App/main"></script> </body> </html> Notice that I set the Layout property for the view to the value null. If you neglect to do this, then the default ASP.NET MVC layout will be applied to the view and you will get the <!DOCTYPE> and opening and closing <html> tags twice. Next, notice that the view contains a DIV element with the Id applicationHost. This marks the area where virtual pages are loaded. When you navigate from page to page in a Durandal app, HTML page fragments are retrieved from the server and stuck in the applicationHost DIV element. Inside the applicationHost element, you can place any content which you want to display when a Durandal app is starting up. For example, you can create a fancy splash screen. I opted for simply displaying the text “Loading app…”: Next, notice the view above includes a call to the Scripts.Render() helper. This helper renders out all of the JavaScript files required by the Durandal library such as jQuery and Knockout. Remember to fix the App_Start\DurandalBundleConfig.cs as described above or Durandal will attempt to load an old version of jQuery and throw a JavaScript exception and stop working. Your application JavaScript code is not included in the scripts rendered by the Scripts.Render helper. Your application code is loaded dynamically by RequireJS with the help of the following SCRIPT element located at the bottom of the view: <script type="text/javascript" src="~/App/durandal/amd/require.js" data-main="/App/main"></script> The data-main attribute on the SCRIPT element causes RequireJS to load your /app/main.js JavaScript file to kick-off your Durandal app. Creating the Durandal Main.js File The Durandal Main.js JavaScript file, located in your App folder, contains all of the code required to configure the behavior of Durandal. Here’s what the Main.js file looks like in the case of the Movies app: require.config({ paths: { 'text': 'durandal/amd/text' } }); define(function (require) { var app = require('durandal/app'), viewLocator = require('durandal/viewLocator'), system = require('durandal/system'), router = require('durandal/plugins/router'); //>>excludeStart("build", true); system.debug(true); //>>excludeEnd("build"); app.start().then(function () { //Replace 'viewmodels' in the moduleId with 'views' to locate the view. //Look for partial views in a 'views' folder in the root. viewLocator.useConvention(); //configure routing router.useConvention(); router.mapNav("movies/show"); router.mapNav("movies/add"); router.mapNav("movies/details/:id"); app.adaptToDevice(); //Show the app by setting the root view model for our application with a transition. app.setRoot('viewmodels/shell', 'entrance'); }); }); There are three important things to notice about the main.js file above. First, notice that it contains a section which enables debugging which looks like this: //>>excludeStart(“build”, true); system.debug(true); //>>excludeEnd(“build”); This code enables debugging for your Durandal app which is very useful when things go wrong. When you call system.debug(true), Durandal writes out debugging information to your browser JavaScript console. For example, you can use the debugging information to diagnose issues with your client-side routes: (The funny looking //> symbols around the system.debug() call are RequireJS optimizer pragmas). The main.js file is also the place where you configure your client-side routes. In the case of the Movies app, the main.js file is used to configure routes for three page: the movies show, add, and details pages. //configure routing router.useConvention(); router.mapNav("movies/show"); router.mapNav("movies/add"); router.mapNav("movies/details/:id");   The route for movie details includes a route parameter named id. Later, we will use the id parameter to lookup and display the details for the right movie. Finally, the main.js file above contains the following line of code: //Show the app by setting the root view model for our application with a transition. app.setRoot('viewmodels/shell', 'entrance'); This line of code causes Durandal to load up a JavaScript file named shell.js and an HTML fragment named shell.html. I’ll discuss the shell in the next section. Creating the Durandal Shell You can think of the Durandal shell as the layout or master page for a Durandal app. The shell is where you put all of the content which you want to remain constant as a user navigates from virtual page to virtual page. For example, the shell is a great place to put your website logo and navigation links. The Durandal shell is composed from two parts: a JavaScript file and an HTML file. Here’s what the HTML file looks like for the Movies app: <h1>Movies App</h1> <div class="container-fluid page-host"> <!--ko compose: { model: router.activeItem, //wiring the router afterCompose: router.afterCompose, //wiring the router transition:'entrance', //use the 'entrance' transition when switching views cacheViews:true //telling composition to keep views in the dom, and reuse them (only a good idea with singleton view models) }--><!--/ko--> </div> And here is what the JavaScript file looks like: define(function (require) { var router = require('durandal/plugins/router'); return { router: router, activate: function () { return router.activate('movies/show'); } }; }); The JavaScript file contains the view model for the shell. This view model returns the Durandal router so you can access the list of configured routes from your shell. Notice that the JavaScript file includes a function named activate(). This function loads the movies/show page as the first page in the Movies app. If you want to create a different default Durandal page, then pass the name of a different age to the router.activate() method. Creating the Movies Show Page Durandal pages are created out of a view model and a view. The view model contains all of the data and view logic required for the view. The view contains all of the HTML markup for rendering the view model. Let’s start with the movies show page. The movies show page displays a list of movies. The view model for the show page looks like this: define(function (require) { var moviesRepository = require("repositories/moviesRepository"); return { movies: ko.observable(), activate: function() { this.movies(moviesRepository.listMovies()); } }; }); You create a view model by defining a new RequireJS module (see http://requirejs.org). You create a RequireJS module by placing all of your JavaScript code into an anonymous function passed to the RequireJS define() method. A RequireJS module has two parts. You retrieve all of the modules which your module requires at the top of your module. The code above depends on another RequireJS module named repositories/moviesRepository. Next, you return the implementation of your module. The code above returns a JavaScript object which contains a property named movies and a method named activate. The activate() method is a magic method which Durandal calls whenever it activates your view model. Your view model is activated whenever you navigate to a page which uses it. In the code above, the activate() method is used to get the list of movies from the movies repository and assign the list to the view model movies property. The HTML for the movies show page looks like this: <table> <thead> <tr> <th>Title</th><th>Director</th> </tr> </thead> <tbody data-bind="foreach:movies"> <tr> <td data-bind="text:title"></td> <td data-bind="text:director"></td> <td><a data-bind="attr:{href:'#/movies/details/'+id}">Details</a></td> </tr> </tbody> </table> <a href="#/movies/add">Add Movie</a> Notice that this is an HTML fragment. This fragment will be stuffed into the page-host DIV element in the shell.html file which is stuffed, in turn, into the applicationHost DIV element in the server-side MVC view. The HTML markup above contains data-bind attributes used by Knockout to display the list of movies (To learn more about Knockout, visit http://knockoutjs.com). The list of movies from the view model is displayed in an HTML table. Notice that the page includes a link to a page for adding a new movie. The link uses the following URL which starts with a hash: #/movies/add. Because the link starts with a hash, clicking the link does not cause a request back to the server. Instead, you navigate to the movies/add page virtually. Creating the Movies Add Page The movies add page also consists of a view model and view. The add page enables you to add a new movie to the movie database. Here’s the view model for the add page: define(function (require) { var app = require('durandal/app'); var router = require('durandal/plugins/router'); var moviesRepository = require("repositories/moviesRepository"); return { movieToAdd: { title: ko.observable(), director: ko.observable() }, activate: function () { this.movieToAdd.title(""); this.movieToAdd.director(""); this._movieAdded = false; }, canDeactivate: function () { if (this._movieAdded == false) { return app.showMessage('Are you sure you want to leave this page?', 'Navigate', ['Yes', 'No']); } else { return true; } }, addMovie: function () { // Add movie to db moviesRepository.addMovie(ko.toJS(this.movieToAdd)); // flag new movie this._movieAdded = true; // return to list of movies router.navigateTo("#/movies/show"); } }; }); The view model contains one property named movieToAdd which is bound to the add movie form. The view model also has the following three methods: 1. activate() – This method is called by Durandal when you navigate to the add movie page. The activate() method resets the add movie form by clearing out the movie title and director properties. 2. canDeactivate() – This method is called by Durandal when you attempt to navigate away from the add movie page. If you return false then navigation is cancelled. 3. addMovie() – This method executes when the add movie form is submitted. This code adds the new movie to the movie repository. I really like the Durandal canDeactivate() method. In the code above, I use the canDeactivate() method to show a warning to a user if they navigate away from the add movie page – either by clicking the Cancel button or by hitting the browser back button – before submitting the add movie form: The view for the add movie page looks like this: <form data-bind="submit:addMovie"> <fieldset> <legend>Add Movie</legend> <div> <label> Title: <input data-bind="value:movieToAdd.title" required /> </label> </div> <div> <label> Director: <input data-bind="value:movieToAdd.director" required /> </label> </div> <div> <input type="submit" value="Add" /> <a href="#/movies/show">Cancel</a> </div> </fieldset> </form> I am using Knockout to bind the movieToAdd property from the view model to the INPUT elements of the HTML form. Notice that the FORM element includes a data-bind attribute which invokes the addMovie() method from the view model when the HTML form is submitted. Creating the Movies Details Page You navigate to the movies details Page by clicking the Details link which appears next to each movie in the movies show page: The Details links pass the movie ids to the details page: #/movies/details/0 #/movies/details/1 #/movies/details/2 Here’s what the view model for the movies details page looks like: define(function (require) { var router = require('durandal/plugins/router'); var moviesRepository = require("repositories/moviesRepository"); return { movieToShow: { title: ko.observable(), director: ko.observable() }, activate: function (context) { // Grab movie from repository var movie = moviesRepository.getMovie(context.id); // Add to view model this.movieToShow.title(movie.title); this.movieToShow.director(movie.director); } }; }); Notice that the view model activate() method accepts a parameter named context. You can take advantage of the context parameter to retrieve route parameters such as the movie Id. In the code above, the context.id property is used to retrieve the correct movie from the movie repository and the movie is assigned to a property named movieToShow exposed by the view model. The movie details view displays the movieToShow property by taking advantage of Knockout bindings: <div> <h2 data-bind="text:movieToShow.title"></h2> directed by <span data-bind="text:movieToShow.director"></span> </div> Summary The goal of this blog entry was to walkthrough building a simple Single Page App using Durandal and to get a feel for what it is like to use this library. I really like how Durandal stitches together Knockout, Sammy, and RequireJS and establishes patterns for using these libraries to build Single Page Apps. Having a standard pattern which developers on a team can use to build new pages is super valuable. Once you get the hang of it, using Durandal to create new virtual pages is dead simple. Just define a new route, view model, and view and you are done. I also appreciate the fact that Durandal did not attempt to re-invent the wheel and that Durandal leverages existing JavaScript libraries such as Knockout, RequireJS, and Sammy. These existing libraries are powerful libraries and I have already invested a considerable amount of time in learning how to use them. Durandal makes it easier to use these libraries together without losing any of their power. Durandal has some additional interesting features which I have not had a chance to play with yet. For example, you can use the RequireJS optimizer to combine and minify all of a Durandal app’s code. Also, Durandal supports a way to create custom widgets (client-side controls) by composing widgets from a controller and view. You can download the code for the Movies app by clicking the following link (this is a Visual Studio 2012 project): Durandal Movie App

• Editing sqlcmdvariable nodes in SSDT Publish Profile files using msbuild

  - by jamiet

  Publish profile files are a new feature of SSDT database projects that enable you to package up all environment-specific properties into a single file for use at publish time; I have written about them before at Publish Profile Files in SQL Server Data Tools (SSDT) and if it wasn’t obvious from that blog post, I’m a big fan! As I have used Publish Profile files more and more I have realised that there may be times when you need to edit those Publish profile files during your build process, you may think of such an operation as a kind of pre-processor step. In my case I have a sqlcmd variable called DeployTag, it holds a value representing the current build number that later gets inserted into a table using a Post-Deployment script (that’s a technique that I wrote about in Implementing SQL Server solutions using Visual Studio 2010 Database Projects – a compendium of project experiences – search for “Putting a build number into the DB”). Here are the contents of my Publish Profile file (simplified for demo purposes) : Notice that DeployTag defaults to “UNKNOWN”. On my current project we are using msbuild scripts to control what gets built and what I want to do is take the build number from our build engine and edit the Publish profile files accordingly. Here is the pertinent portion of the the msbuild script I came up with to do that:   <ItemGroup>     <Namespaces Include="myns">       <Prefix>myns</Prefix>       <Uri>http://schemas.microsoft.com/developer/msbuild/2003</Uri>     </Namespaces>   </ItemGroup>   <Target Name="UpdateBuildNumber">     <ItemGroup>       <SSDTPublishFiles Include="$(DESTINATION)\**\$(CONFIGURATION)\**\*.publish.xml" />     </ItemGroup>     <MSBuild.ExtensionPack.Xml.XmlFile Condition="%(SSDTPublishFiles.Identity) != ''"                                        TaskAction="UpdateElement"                                        File="%(SSDTPublishFiles.Identity)"                                        Namespaces="@(Namespaces)"                                         XPath="//myns:SqlCmdVariable[@Include='DeployTag']/myns:Value"                                         InnerText="$(BuildNumber)"/>   </Target> The important bits here are the definition of the namespace http://schemas.microsoft.com/developer/msbuild/2003: and the XPath expression //myns:SqlCmdVariable[@Include='DeployTag']/myns:Value: Some extra info: I use a fantastic tool called XMLPad to discover/test XPath expressions, read more at XMLPad – a new tool in my developer utility belt MSBuild.ExtensionPack.Xml.XmlFile is a msbuild task used to edit XML files and is available from Mike Fourie’s MSBuild Extension Pack I’m using a property called $(BuildNumber) to hold the value to substitute into the file and also $(DESTINATION)\**\$(CONFIGURATION)\**\*.publish.xml to define an ItemGroup all of my Publish Profile files. Populating those properties is basic msbuild stuff and is therefore outside the scope of this blog post however if you want to learn more check out MSBuild properties & How To: Use Wildcards to Build All Files in a Directory. Hope this is useful! @Jamiet

• Mobile game production workflow using Html5 and visual studio

  - by Mihalis Bagos

  I want to know of any framework, that lets you build/test applications inside Visual Studio using Html5/JS. We need to be able to have an emulator (like the one on android sdk) for as many devices as possible, and we need to be able to run the application with as few steps as possible (using the "RUN" command in visual studio is no1 choice). Also, this extends to build and deployment to app stores. Is there a way to circumvent the cloud services and build locally? I am at a loss of the plethora of tools and technologies available for game design using Html5. However, I really don't like the way implementations try to get you to rely on their cloud services, so services like appmobi are at the bottom of the favored list.

• Cool a Computer with Toilet Water

  - by Jason Fitzpatrick

  When most people opt to use water cooling they put together tidy coolant reservoirs complete with ambient lighting and the like. This build involves a hole in the wall and the tank of a functioning toilet. The design, courtesy of Jeff Gagnon, is unconventional, but effective. Opposite of his wall-mounted PC is a bathroom. In that bathroom he has a coolant pump in the tank of the toilet. Using the toilet tank as a thermal sink he keeps the CPU at a nice chilly 66F. Hit up the link below for more pictures, including a peek inside his hacked together toilet-tank cooling rig.

• How to attach WAR file in email from jenkins

  - by birdy

  We have a case where a developer needs to access the last successfully built WAR file from jenkins. However, they can't access the jenkins server. I'd like to configure jenkins such that on every successful build, jenkins sends the WAR file to this user. I've installed the ext-email plugin and it seems to be working fine. Emails are being received along with the build.log. However, the WAR file isn't being received. The WAR file lives on this path in the server: /var/lib/jenkins/workspace/Ourproject/dist/our.war So I configured it under Post build actions like this: The problem is that emails are sent but the WAR file isn't being attached. Do I need to do something else?

• Building Paths Fluently

  - by PSteele

  If you ever need to “build” a path (i.e. “C:\folder1\subfolder”), you really should be using Path.Combine.  It makes sure the trailing directory separator is in between the two paths (and it puts the appropriate character in – DirectorySeparatorChar).  I wanted an easier way to build a path than having to constantly call Path.Combine so I created a handy little extension method that lets me build paths “fluently”: public static string PathCombine(this string path1, string path2) { return Path.Combine(path1, path2); } Now I can write code like this: var dir = Environment.GetFolderPath(Environment.SpecialFolder.MyDocuments) .PathCombine("Folder1") .PathCombine("Folder2"); Technorati Tags: .NET,Extension Methods,Fluent

• Telecomunication SID model and resources [on hold]

  - by andygluk

  There is a SID model well-known in telecom industry. Following this model you define resources as resources owned by your enterprise, and then you build resource-oriented services on top of it and then customer-oriented services and so on... So everything is based on enterprise-owned resources, which you have to identify first. What I am looking for and what I am asking is some alternative to this model, build not on enterprise-owned resources, but on resources sell by enterprise. Say, you are selling licenses for using your products. So instead of building model on top of enterprise resources you may be interested to build it on top of licenses you are selling.

• Building TrueCrypt on Ubuntu 13.10

  - by linuxubuntu

  With the whole NSA thing people tried to re-build identically looking binaries to the ones which truecrypt.org provides, but didn't succeed. So some think they might be compiled with back-doors which are not in the source code. - So how compile on the latest Ubuntu version (I'm using UbuntuGNOME but that shouldn't matter)? I tried some tutorials for previous Ubuntu versions but they seem not to work any-more? edit: https://madiba.encs.concordia.ca/~x_decarn/truecrypt-binaries-analysis/ Now you might think "ok, we don't need to build", but: To build he used closed-source software and there are proof-of-concepts where a compromised compiler still put backdoors into the binary: 1. source without backdoors 2. binary identically to the reference-binary 3. binary contains still backdoors

• Should maven generate jaxb java code or just use java code from source control?

  - by Peter Turner

  We're trying to plan how to mash together a build server for our shiny new java backend. We use a lot of jaxb XSD code generation and I was getting into a heated argument with whoever cared that the build server should delete jaxb created structures that were checked in generate the code from XSD's use code generated from those XSD's Everyone else thought that it made more sense to just use the code they checked in (we check in the code generated from the XSD because Eclipse pretty much forces you to do this as far as I can tell). My only stale argument is in my reading of the Joel test is that making the build in one step means generating from the source code and the source code is not the java source, but the XSD's because if you're messing around with the generated code you're gonna get pinched eventually. So, given that we all agree (you may not agree) we should probably be checking in our generate java files, should we use them to generate our code or should we generate it using the XSD's?
