• How to start a task before networking?

  - by user1252434

  I've written an upstart task that modifies /etc/network/interfaces. (Actually a file sourced into it.) Which start on condition do I need to declare to let my task run before any networking jobs? I've tried start on starting networking, but that's apparently too late. When I log in after booting I can see that the changes were written, but obviously they are not used: the new config states a static IP, but the boot process waits for a non-existing DHCP server (old config) to time out. I've also tried start on starting network-interface INTERFACE=eth0, which didn't work either. IIRC there was an error in the log that the change couldn't be written. Background: I need a VM template that can be cloned and the clones configured through a script. Among other settings, I need to give them a static IP address to access them from the host. I use guestfish to write a config file to one of the virtual disks and let a script apply these settings to the system. I don't want that disk to contain an actual system settings file. I can't modify /etc directly, because that disk is shared (copy-on-write/diff) among the clones and guestfish apparently doesn't support that type of image. I could also let them use DHCP and setup a server that assigns IP by MAC, but I'm afraid of the complexity. I could also add just another virtual disk for configuration files, but if possible I'd prefer to store settings directly on the system disk image. Used software: Ubuntu Server 12.04, VirtualBox. The configuration modifier is a self written ruby script.

• Double entries in the gnome 3 task bar

  - by Mark

  I am running Ubuntu 12.04 with Gnome 3. All was working well except that graphics were slow and even moving a window on the screen seemed slow. I installed the fglrx ati driver. Which seems to have improved matters. But on first login I had all gnome items duplicated. That is my task bar has the ubuntu sign, then says Applications, then places then the ubuntu sign then Aplications and then places. Any application I run produces two icons at the bottom of the screen. This was after a reboot. I rebooted again. Now I have 3!! On the right each set of icons such as printer is also trippled!! See screenshot at http://jetmark.co.uk/Screenshot.png See Dmesg at http://jetmark.co.uk/dmesg.txt Any suggestions welcome. Reboot - now I have 4!! So one set gets added on each reboot. Help!! I am going to be task barred out before long!!

• Calculation of Milestones/Task list

  - by sugar

  My project manager assigned me a task to estimate the development time for an iPad application. Lets assume that I gave estimation of 15 working days. He thought that the number of days where too many and client needed the changes to the application urgently (as in most of cases). So, he told me: "I am going to assign two developer including you and as per my understandings and experience it won't take more than seven working days." Clarifications I was given the task of estimating development time for an individual. How could I be sure that 2 developers are going to finish it within 7 days? (I am new to team & I hardly know the others abilities) Questions Why do most of project managers / team leaders have understandings like: If one developer requires N days, Then two developers would require N/2 days, Do they think something like developer = s/w production machines? Should a team member (developer, not team lead or any higher post) estimate other developers work? I didn't deny anything in the meeting and didn't said, but what should be the appropriate answer to convince them that N/2 formula that they follow is not correct?

• Task-It Source Code

  Download Source Code I've received many questions about when the source code for the Task-It application will be released. Well, the time has finally come. I haven't been able to release this sooner due to the flurry of releases that have been coming out lately. Silverlight 4, WCF RIA Services, and even our Q1 Rad Controls. Each time I got the latest bits I ran into issues (either bugs or visual issues) in the Task-It that needed to be fixed. Having said that, the app is far from perfect. There are still some bugs lurking and things that need to be fixed up visually (especially the RadGridView filtering popup), but the main purpose of this app is to show the RadControls for Silverlight 4 in the context of a real-world application, and I don't want to keep delaying the release of the source code. Minimum requirements To run the app you will need the latest Silverlight bits.

• Using the RadTransitionControl in Task-It

  Download Source Code NOTE: To run the source code provided your will need to update to the RC (release candidate) versions of Silverlight 4 and VisualStudio 2010.  In a recent Ask the Experts webinar I showed a simple solution that had similarities to one that I had used in my recent MVVM post, but had a few extra twists on it. I have since been asked if I could post the source code for this demo, so here it is (I am using similar techniques in my Task-It application). The database Before running the code for this app you will need to create the database. First, create a database called MVVMProject in SQL Server, then run MVVMProject.sql in the MVVMProjectDemo/Database directory of your downloaded .zip file. This should give you a Task table with 3 records in it. You will also need to update the connection string in web.config to point to your database ...Did you know that DotNetSlackers also publishes .net articles written by top known .net Authors?

• How to pass -f specdoc option through rake task

  - by dorelal

  I am using rails 2.3.5 .rake spec works fine. This is from spec --help. spec --help -f, --format FORMAT[:WHERE] Specifies what format to use for output. Specify WHERE to tell the formatter where to write the output. All built-in formats expect WHERE to be a file name, and will write to $stdout if it's not specified. The --format option may be specified several times if you want several outputs Builtin formats: silent|l : No output progress|p : Text-based progress bar profile|o : Text-based progress bar with profiling of 10 slowest examples specdoc|s : Code example doc strings nested|n : Code example doc strings with nested groups indented html|h : A nice HTML report failing_examples|e : Write all failing examples - input for --example failing_example_groups|g : Write all failing example groups - input for --example How do I pass -f specdoc through rake task.

• mysterious difference between rake test and ruby

  - by standup75

  Here is the mysterious: I have a scope which looks like this (in Image.rb) scope :moderate_all, delegates.where("moderation_flag = #{$moderation_flags[:not_moderated]}") Note that delegates is another scope that I am defining before moderate_all When I leave it like this, I can run my test that checks if an image has been "checked-out" it is not available anymore. I don't put the code of the test, because it does not matter actually. With this code, when I run "rake test" it fails, but if I do "ruby test/unit/image_test.rb" it works! I was thinking I am starting to have a bad day. Then I tried scope :moderate_all, lambda { delegates.where("moderation_flag = #{$moderation_flags[:not_moderated]}") } And "rake test" passes! So my problem is solved, but why?

• rake db:create not working for legacy rails app (2.3.5) using MySQL (5.5.28)

  - by ridicter

  I'm a new Rails Developer, and I'm working on a legacy Rails app. Whenever I run the rake db:create command, I get an error that the database couldn't be created. I have found many StackOverflow questions related to this, but in troubleshooting nearly all permutations of solutions, I couldn't resolve the issue. I created the three Dbs (dev, prod, test), created the user with all access privileges to these dbs, and ran rake db:create. I'm running Mac OS X Lion, MySQL 5.5.28, Rails 2.3.5, Ruby 1.8.7. Here are my settings development: adapter: mysql encoding: utf8 database: adva_development username: adva password: **** host: localhost socket: /tmp/mysql.sock Here's the error: Couldn't create database for {"adapter"=>"mysql", "username"=>"adva", "host"=>"localhost", "encoding"=>"utf8", "database"=>"adva_development", "socket"=>"/tmp/mysql.sock", "password"=>"****"}, charset: utf8, collation: utf8_unicode_ci (if you set the charset manually, make sure you have a matching collation) I have done the following troubleshooting: Verified user and password are correct, and the user has access to the DB. (Double checked user access with SELECT * FROM mysql.db WHERE Db = 'adva_development' \G; User has all privileges.) Verify the socket is correct. I don't really understand sockets, but I can plainly see it at /tmp/mysql.sock. Checked collation and character set. I found out I had created the DB in latin charset and collation, so I recreated them. I ran show variables like "collation_database"; and show variables like "character_set_database"; and came back with utf8 and utf8_unicode_ci respectively. I followed the instructions in this question. After uninstalling mysql gem, I ran the following but came up with the same error: gem install --no-rdoc --no-ri mysql -- --with-mysql-dir=/usr/local/mysql-5.5.28-osx10.6-x86_64/bin --with-mysql-config=/usr/local/mysql-5.5.28-osx10.6-x86_64/bin/mysql_config Following Matt's suggestion, here's what a rake --trace db:create reveals: ** Invoke db:create (first_time) ** Invoke db:load_config (first_time) ** Invoke rails_env (first_time) ** Execute rails_env ** Execute db:load_config ** Execute db:create Couldn't create database for {"database"=>"adva_development", "adapter"=>"mysql", "host"=>"127.0.0.1", "password"=>"woof2adva", "username"=>"adva", "encoding"=>"utf8"}, charset: utf8, collation: utf8_unicode_ci (if you set the charset manually, make sure you have a matching collation) After 3 days and six or seven hours, I have pretty much run out of options. I tried various random things, like replacing localhost with 127.0.0.1 to no avail. Could there be something wrong related to my specific environment? Mac OS X Lion + MySQL 5.5.28? I plan on trying on setting up everything in a Linux environment. Thanks!

• Task-It Webinar - Source Code

  Last week I presented a webinar called "Building a real-world application with RadControls for Silverlight 4". For those that didn't get to see the webinar, you can view it here: Building a read-world application with RadControls for Silverlight 4 Since the webinar I've received several requests asking if I could post the source code for the simple application I showed demonstrating some of the techniques used in the development of Task-It, such as MVVM, Commands and Internationalization. This source code is now available for downloadhere. After downloading the source: Extract it to the location of your choice on your hard-drive Open the solution Right-click ModuleProject.Web and selecte 'Set as StartUp Project'. Right-click ProjectTestPage.aspx and selected 'Set as Start Page' Create a database in SQL Server called WebinarProject. Navigate to the Database folder under the WebinarProject directory and run the .sql script against your WebinarProject database. The last two steps are necessary only for the Tasks page to work properly (using WCF RIA Services). Now some notes about each page: Code-behind This is not the way I recommend coding a line-of-business application in Silverlight, but simply wanted to show how the code-behind approach would look. Command This page introduces MVVM and Commands. You'll notice in the XAML that the Command property of theRadMenuItem and the Button are both bound to a SaveCommand. That comes from the view model. If you look in the code- behind of the user control you'll see that an instance of a CommandViewModel is instantiated and set as the DataContext of the UserControl.There is also a listener for the view model's SaveCompleted event. When this is fired, it tells the view (UserControl) to display the MessageBox. Internationalization This sample is similar to the previous one, but instead of using hard-coded strings in the UI, the strings are obtained via binding toview model properties. The view model gets the strings from the .resx files (Strings.resx or Strings.de.resx) under Assets/Resources. If you uncomment the call to ShowGerman() in App.xaml.cs's Application_Startup method and re-run the application, you will see the UI in German. Note that this code, which sets the CurrentCulture and CurrentUICulture on the current thread to "de" (German) is for testing purposes only. RadWindow Once again, very similar to the previous example.The difference is that we are now using a RadWindow to display the 'Saved' message instead of a MessageBox. The advantage here is that we do not have to hold on to a reference to the view model in our code behind so that we can get the 'Saved' message from it. The RadWindow's DataContext is now also bound to the view model, so within its XAML we can bind directly to properties in the view model. Much nicer, and cleaner. One other thing I introduced in this example is the use of spacer Rectangles. Rather than setting a width and/or height on the rectangles for spacing, I am now referencing a style in my ResourceDictionary called StandardSpacerStyle. I like doing this better than using margins or padding because now I have a reusable way to create space between elements, the Rectangle does not show (because I have not set its Fill color), and I can change my spacing throughout the user interface in one place if I'd like. Tasks This page is quite a bit different than the other four. It is a very simple, stripped-down version of the Tasks page in the Task-It application. The Tasks.xaml UserControl has a ContentControl, and the Content of that control is set based on whether we are looking at the list of tasks or editing a task. So it displays one of two child UserControls, which are called List and Details. List has the RadGridView, Details has the form. In the code-behind of the Tasks UserControl I am once again setting its DataContext to a view model class. The nice thing is, whichever child UserControl is being displayed (List or Details) inherits its DataContext from its parent control (Tasks), so I do not have to explicitly set it. The List UserControl simply displays a RadGridView whose ItemsSource is bound to a property in the view model called Tasks, and its SelectedItem property is bound to a property in the view model called SelectedItem. The SelectedItem binding must be TwoWay so that the view is notified when the SelectedItem changes in the view model, and the view model is notified when something changes in the view (like when a user changes the Name and/or DueDate in the form). You'll also notice that the form's TextBox and RadDatePicker are also TwoWay bound to the SelectedItem property in the view model. You can experiment with the binding by removing TwoWay and see how changes in the form do not show up in the RadGridView. So here we have an example of two different views (List and Details) that are both bound to the same view model...and actually, so is the Tasks UserControl, so it is really three views. WCF RIA Services By the way, I am using WCF RIA Services to retrieve data for the RadGridView and save the data when the user clicks the Save button in the form. I created a really simple ADO.NET Entity Data Model in WebinarProject.Web called DataModel.edmx. I also created a simple Domain Data Service called DataService that has methods for retrieving data, inserting, updating and deleting. However I am only using the retrieval and update methods in this sample. Note that I do not currently have any validation in place on the form, as I wanted to keep the sample as simple as possible. Wrap up Technically, I should move the calls to WCF RIA Services out of the view model and put them into a separate layer, but this works for now, and that is a topic for another day!

• Sharepoint Workflow "Failed on Start" only when powershell import script is called from task scheduler

  - by Matt Keller

  I created a simple PowerShell script that takes an XML file in a local directory on our sharepoint server and imports it into a specific SharePoint form library. (Content management enabled library if that makes any difference) This script works flawlessly if i run it from the PowerShell command line manually. I call it like such: ".\script_name.ps1". It completes without error and the item is imported into the form library successfully. The workflow begins on the item and everything is happy dandy. However, i run into issues when i setup a scheduled task using Windows Server 2008 R2's task manager. The task runs the script without error and it does actually import the XML into the form library. I looks perfectly normal just as if i had run the script manually. However, after about 10 or 20 minutes the workflow status for that item changes from "In progress" to "Failed on Start (Retrying)". The scheduled task in question is a basic task and has only one action. (Start a program) The "program/script" box is set to "C:\Windows\System32\WindowsPowerShell\v1.0\powershell.exe" and the "Add arguments" box is set to the path of the actual ps1 script. (C:\scripts\sharepoint_import.ps1) I've tried running the task as various users. I've also tried with and without the "Run with highest privileges" check box. Nothing seems to work. For reference, here is the script i am using to import items into the form library.

• Sever 2008 R2 Powershell Script runs manually, but not as a scheduled task

  - by Aeisor

  I have a Powershell script that runs manually using the Powershell ISE; However, when run as a scheduled task using an administrator's credentials the task does not run with the expected results. The script: $request=new-object System.Net.WebClient $request.DownloadFile("...url...", "C:\path\to\file.csv") The administrator user has Full Control of both the script and the folder it is writing to. The url exists and responds in a reasonable time (<1s). If I run the task manually the status is 0x41301 ("Currently Running") until I eventually end it. I have set the task up using both of these methods: Start a Program: C:\path\to\PS.PS1 Start a Program: C:\windows\system32\WindowsPowerShell\v1.0\powershell.exe with additional options -noninteractive -command "C:\path\to\PS.PS1" Using option 1, the task history shows it has opened an instance of notepad.exe but never terminates it. Using option 2 it completes the task but doesn't download / create the file. I have used Set-ExecutionPolicy Unrestricted as this is not a signed script. Any ideas?

• Any task-control algorithms programming practices?

  - by NumberFour

  Hi, I was just wondering if there's any field which concerns the task-control programming (or at least that's the way I call it). For a better explanation of task-control consider the following scenario: An application (master-thread) waits for a command - which might be a particular action or a set of actions the application should perform. When a command is received the master-thread creates a task (= spawns an independent thread which actually does the action) and adds a record in it's task-list - thus keeping track of the time of execution, thread handle, task priority...etc. The master-thread awaits for any other incoming commands while taking care of all the tasks - e.g: kills tasks running too long, prioritizes tasks with higher priorities, kills a task on a request of another task, limits the number of currently running tasks, allows task scheduling, cleans finished tasks (threads) and so on. The model is pretty similar to what we can see in OS dealing with running processes. Are there any good practices programming such task-models or is there some theoretical work done in this field? Maybe my question is too generalized, but at least I wanted to know whether there are any experiences working on such models or if there's a better approach. Thanks for any answers.

• Updating Workflow Task without Correlation Token

  - by Khurram Aziz

  I have inhertied a sequential sharepoint workflow which deals with multiple tasks for different people; multi step approval based on certain condition..For each approval new task is created and monitored...For some reason; we have decided to use single task for the whole workflow and the single task will get assigned to required person at different stages...this will help us reduce the cluter in the task list For refactoring it; I am trying to create "CreateOrUpdateTaskAndWaitForCompletition" activity...so that I can use this component multiple times as per given workflow. Create/Wait branch of my activity works fine; as I have the correlation token within the activity. But when I try two instances of this activity; task is created in first activity and it needs to be updated in second instance where I dont have the correlation token. In the second instance; (Update/Wait branch) I have tried updating the task through code activity but its not working and I am getting "This task is currently locked by a running workflow and cannot be edited" exception! Can I use UpdateTask activity without correlation token? Can I programmatically update the workflow task? Can I programmatically unlock the workflow task?

• Fix: SqlDeploy Task Fails with NullReferenceException at ExtractPassword

  Still working on getting a TeamCity build working (see my last post).  Latest exception is: C:\Program Files\MSBuild\Microsoft\VisualStudio\v9.0\TeamData\Microsoft.Data.Schema.SqlTasks.targets(120, 5): error MSB4018: The "SqlDeployTask" task failed unexpectedly. System.NullReferenceException: Object reference not set to an instance of an object. at Microsoft.Data.Schema.Common.ConnectionStringPersistence.ExtractPassword(String partialConnection, String dbProvider) at Microsoft.Data.Schema.Common.ConnectionStringPersistence.RetrieveFullConnection(String partialConnection, String provider, Boolean presentUI, String password) at Microsoft.Data.Schema.Sql.Build.SqlDeployment.ConfigureConnectionString(String connectionString, String databaseName) at Microsoft.Data.Schema.Sql.Build.SqlDeployment.OnBuildConnectionString(String partialConnectionString, String databaseName) at Microsoft.Data.Schema.Build.Deployment.FinishInitialize(String targetConnectionString) at Microsoft.Data.Schema.Build.Deployment.Initialize(FileInfo sourceDbSchemaFile, ErrorManager errors, String targetConnectionString) at Microsoft.Data.Schema.Build.DeploymentConstructor.ConstructServiceImplementation() at Microsoft.Data.Schema.Extensibility.ServiceConstructor'1.ConstructService() at Microsoft.Data.Schema.Tasks.DBDeployTask.Execute() at Microsoft.Build.BuildEngine.TaskEngine.ExecuteInstantiatedTask(EngineProxy engineProxy, ItemBucket bucket, TaskExecutionMode howToExecuteTask, ITask task, Boolean& taskResult)   This time searching yielded some good stuff, including this thread that talks about how to resolve this via permissions.  The short answer is that the account that your build server runs under needs to have the necessary permissions in SQL Server.  Youll need to create a Login and then ensure at least the minimum rights are configured as described here: Required Permissions in Database Edition Alternately, you can just make your buildserver account an admin on the database (which is probably running on the same machine anyway) and at that point it should be able to do whatever it needs to. If youre certain the account has the necessary permissions, but youre still getting the error, the problem may be that the account has never logged into the build server.  In this case, there wont be any entry in the HKCU hive in the registry, which the system is checking for permissions (see this thread).  The solution in this case is quite simple: log into the machine (once is enough) with the build server account.  Then, open Visual Studio (thanks Brendan for the answer in this thread). Summary Make sure the build service account has the necessary database permissions Make sure the account has logged into the server so it has the necessary registry hive info Make sure the account has run Visual Studio at least once so its settings are established In my case I went through all 3 of these steps before I resolved the problem.

• Is it too early to start designing for Task Parallel Library?

  - by Joe Erickson

  I have been following the development of the .NET Task Parallel Library (TPL) with great interest since Microsoft first announced it. There is no doubt in my mind that we will eventually take advantage of TPL. What I am questioning is whether it makes sense to start taking advantage of TPL when Visual Studio 2010 and .NET 4.0 are released, or whether it makes sense to wait a while longer. Why Start Now? The .NET 4.0 Task Parallel Library appears to be well designed and some relatively simple tests demonstrate that it works well on today's multi-core CPUs. I have been very interested in the potential advantages of using multiple lightweight threads to speed up our software since buying my first quad processor Dell Poweredge 6400 about seven years ago. Experiments at that time indicated that it was not worth the effort, which I attributed largely to the overhead of moving data between each CPU's cache (there was no shared cache back then) and RAM. Competitive advantage - some of our customers can never get enough performance and there is no doubt that we can build a faster product using TPL today. It sounds fun. Yes, I realize that some developers would rather poke themselves in the eye with a sharp stick, but we really enjoy maximizing performance. Why Wait? Are today's Intel Nehalem CPUs representative of where we are going as multi-core support matures? You can purchase a Nehalem CPU with 4 cores which share a single level 3 cache today, and most likely a 6 core CPU sharing a single level 3 cache by the time Visual Studio 2010 / .NET 4.0 are released. Obviously, the number of cores will go up over time, but what about the architecture? As the number of cores goes up, will they still share a cache? One issue with Nehalem is the fact that, even though there is a very fast interconnect between the cores, they have non-uniform memory access (NUMA) which can lead to lower performance and less predictable results. Will future multi-core architectures be able to do away with NUMA? Similarly, will the .NET Task Parallel Library change as it matures, requiring modifications to code to fully take advantage of it? Limitations Our core engine is 100% C# and has to run without full trust, so we are limited to using .NET APIs.

• Why does this VBS scheduled task (to call a URL) not work in Windows Server 2008?

  This same script worked in older server OS environments, and even on my desktop; and allows me to kick off a nightly process on my website's URL. It simply will not execute the URL in my Windows Server 2008 environment. It does not generate any errors, claiming task completion I can pull the same URL up just fine in the server's web browser I have the script running with "highest privileges" I even tried to create a batch file which executes it, so I can explicitly "Run as Administrator" and it still will not execute the URL (but will not generate any errors either). I'm baffled as to why the task claims to have completed successfully, yet the script never reaches the URL. Call LogEntry() Sub LogEntry() 'Force the script to finish on an error. On Error Resume Next 'Declare variables Dim objRequest Dim URL Set objRequest = CreateObject("MSXML2.ServerXMLHTTP") 'Put together the URL link appending the Variables.

• Tasks API using Google Apps Script (complete task)

  - by Cartman

  I am trying to set the status of a task as completed using Tasks API. It shows that the code has completed successfully, but the task is not being marked as completed. Also, when I try to get the status of the task after update, it shows status as "needsAction". Here is my code function setTaskStatus(){ // Suppose a task with name "MyTaskListName" is contained //within task list with name "MyTaskName" var tasklist = Tasks.Tasklists.list().getItems(); var title = 'MyTaskListName'; var id; for(var i in tasklist){ if(title == tasklist[i].getTitle()){ id = tasklist[i].getId(); } } //Get the task list items var tasks = Tasks.Tasks.list(id).getItems(); for(var i in tasks){ if(tasks[i].getTitle() == 'MyTaskName'){ tasks[i].setStatus("completed");// set status completed Logger.log(tasks[i].getStatus());// this shows that the task has completed //But it does not reflect actually } } }
