  • Microsoft Team System Equivalent stack.

    - by Nix
    I am looking for a free alternative to TS. What would be the best alternative stack(source control, bug tracking, project management/planning, wiki, automated builds (ci))? Keeping in mind that it would be nice if they all integrated well. For example, it would be nice to be able to link bugs to source control, and then be able to link to a project plan and then be able to automate building. I do not have issues with using Microsoft project to manage project planing. I know i would like to use these....: SVN TeamCity NUnit But i am struggling to find a good Wiki/Project Planning/Bug tracking, that would integrate well. Any questions let me know.

  • In a team practicing Domain Driven Design, should the whole team participate in Stakeholder meetings?

    - by thirdy
    In my experience, a Software Development Team that comprises: 1 Project Manager 1 Tech Lead 1 - 2 Senior Dev 2 - 3 Junior Dev (Fresh grad) Only the Tech Lead & PM (and/or Senor Dev/s) will participate in a meeting with Clients, Domain Experts, Client's technical resource. I can think of the ff potential pitfalls: Important info gets lost Human error (TL/PM might forgot to disseminate info due to pressure or plain human error) Non-verbal info (maybe a presentation using a diagram presented by Domain Expert) Maintaining Ubiquitous language is harder to build since not all team members get to hear the non-dev persons Potential of creative minds are not fully realized (Personally, I am more motivated to think/explore when I am involved with these important meetings) Advantages of this approach: Only one point of contact Less time spent on meetings? Honestly, I am biased & against this approach. I would like to hear your opinions. Is this how you do it in your team? Thanks in advance!

  • Merging all changesets associated with a WorkItem in Team Foundation Server

    - by Rowland Shaw
    We're trailing the use of the built in bug tracking, and have written some integration into our helpdesk software that allows for escalation via workitems. One thing I haven't found out how to do, is to merge all changes associated with a work item (say to go from dev branch to main) - I appreciate you can double click on a changeset in the merge dialog to view if it is associated with a workitem, and also that I can select individual changesets, and groups of adjacent changesets; but there doesn't appear to be any way to merge changes by workitem?

  • Partial Trust in WPF 4

    - by Hadi Eskandari
    I've started a new project in WPF 4 (.NET 4) and trying to see if I can run it in xbap mode. I need to run the application in Full Trust with the new mode made available in .NET 4 which asks the end user if the full trust application should be run. I've set the "Security" mode to "Full Trust" application, and it builds just fine. When I run it, an exception is thrown and IE error message shows the following error. Any ways around it??

  • ObjectContext.SaveChanges() fails with SQL CE

    - by David Veeneman
    I am creating a model-first Entity Framework 4 app that uses SQL CE as its data store. All is well until I call ObjectContext.SaveChanges() to save changes to the entities in the model. At that point, SaveChanges() throws a System.Data.UpdateException, with an inner exception message that reads as follows: Server-generated keys and server-generated values are not supported by SQL Server Compact. I am completely puzzled by this message. Any idea what is going on and how to fix it? Thanks. Here is the Exception dump: System.Data.UpdateException was unhandled Message=An error occurred while updating the entries. See the inner exception for details.

  • nginx bad gateway 502 with mono fastcgi

    - by Bradley Lederholz Leatherwood
    Hello so I have been trying to get my website to run on mono (on ubuntu server) and I have followed these tutorials almost to the letter: However when my directory is not blank fastcgi logs reveal this: Notice Beginning to receive records on connection. Error Failed to process connection. Reason: Exception has been thrown by the target of an invocation. I am not really sure what this means, and depending on what I do I can get another error that tells me the resource cannot be found: The resource cannot be found. Description: HTTP 404. The resource you are looking for (or one of its dependencies) could have been removed, had its name changed, or is temporarily unavailable. Please review the following URL and make sure that it is spelled correctly. Requested URL: /Default.aspx/ Version information: Mono Runtime Version: 2.10.8 (tarball Thu Aug 16 23:46:03 UTC 2012) ASP.NET Version: 4.0.30319.1 If I should provide some more information please let me know. Edit: I am now getting a nginx gateway error. My nginx configuration file looks like this: server { listen 2194; server_name localhost; access_log $HOME/WWW/nginx.log; location / { root $HOME/WWW/dev/; index index.html index.html default.aspx Default.aspx Index.cshtml; fastcgi_index Views/Home/; fastcgi_pass 127.0.0.1:8000; include /etc/nginx/fastcgi_params; } } Running the entire thing with xsp4 I have discovered what the "Exception has been thrown by the target of an invocation." Handling exception type TargetInvocationException Message is Exception has been thrown by the target of an invocation. IsTerminating is set to True System.Reflection.TargetInvocationException: Exception has been thrown by the target of an invocation.

  • How can I get System.Type from "System.Drawing.Color" string

    I have an xml stored property of some control <Prop Name="ForeColor" Type="System.Drawing.Color" Value="-16777216" /> I want to convert it back as others System.Type type = System.Type.GetType(propertyTypeString); object propertyObj = TypeDescriptor.GetConverter(type).ConvertFromString(propertyValueString); System.Type.GetType("System.Drawing.Color") returns null. The question is how one can correctly get color type from string (it will be better not to do a special case just for Color properties) Update from time to time this xml will be edited by hand

  • mod_mono 'Service Temporarily Unavailable' issue

    - by Charlie Somerville
    I've deployed an ASP.NET web application on a Linux (Debian) server running Apache 2.2 and mod_mono 1.9 It's working well, however Mono occasionally segfaults and uses the entire CPU which causes the website to stop working and display 'Service Temporarily Unavailable' Killing mono fixes it, but obviously this isn't a good solution. I tailed the system log after this happened and I saw the following error messages from the kernel: Apr 20 01:49:37 charliesomerville kernel: [1596436.204158] mono[17909]: segfault at b645f671 ip b645f671 sp b4ffb604 error 4<6>mono[19047]: segfault at b645f66e ip b645f66e sp b4bf7604 error 4<6>mono[18017]: segfault at b645f66e ip b645f66e sp b52fe604 error 4<6>mono[19668]: segfault at b645f5e6 ip b645f5e6 sp b48f4604 error 4<6>mono[22565]: segfault at b645f674 ip b645f674 sp b45f1604 error 4<6>mono[17700]: segfault at b645f661 ip b645f661 sp b51fd604 error 4<6>mono[19596]: segfault at b645f5e6 ip b645f5e6 sp b49f5604 error 4 Apr 20 01:49:37 charliesomerville kernel: [1596436.208172] mono[23219]: segfault at b645f66e ip b645f66e sp b44f0604 error 4 At the end of Apache's error.log are the following errors: [Tue Apr 20 03:10:23 2010] [error] (70014)End of file found: read_data failed [Tue Apr 20 03:10:23 2010] [error] Command stream corrupted, last command was 1 [Tue Apr 20 03:10:23 2010] [error] Command stream corrupted, last command was 1 [Tue Apr 20 03:10:23 2010] [error] Command stream corrupted, last command was 1 System.ArgumentNullException: null key Parameter name: key at System.Collections.Hashtable.get_Item (System.Object key) [0x00000] at System.Runtime.Serialization.SerializationCallbacks.GetSerializationCallbacks (System.Type t) [0x00000] at System.Runtime.Serialization.ObjectManager.RaiseOnDeserializingEvent (System.Object obj) [0x00000] at System.Runtime.Serialization.Formatters.Binary.ObjectReader.ReadObjectContent (System.IO.BinaryReader reader, System.Runtime.Serialization.Formatters.Binary.TypeMetadata metadata, Int64 objectId, System.Object& objectInstance, System.Runtime.Serialization.SerializationInfo& info) [0x00000] at System.Runtime.Serialization.Formatters.Binary.ObjectReader.ReadObjectInstance (System.IO.BinaryReader reader, Boolean isRuntimeObject, Boolean hasTypeInfo, System.Int64& objectId, System.Object& value, System.Runtime.Serialization.SerializationInfo& info) [0x00000] at System.Runtime.Serialization.Formatters.Binary.ObjectReader.ReadObject (BinaryElement element, System.IO.BinaryReader reader, System.Int64& objectId, System.Object& value, System.Runtime.Serialization.SerializationInfo& info) [0x00000] at System.Runtime.Serialization.Formatters.Binary.ObjectReader.ReadNextObject (System.IO.BinaryReader reader) [0x00000] at System.Runtime.Serialization.Formatters.Binary.ObjectReader.ReadObjectGraph (System.IO.BinaryReader reader, Boolean readHeaders, System.Object& result, System.Runtime.Remoting.Messaging.Header[]& headers) [0x00000] at System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.NoCheckDeserialize (System.IO.Stream serializationStream, System.Runtime.Remoting.Messaging.HeaderHandler handler) [0x00000] at System.Runtime.Serialization.Formatters.Binary.BinaryFormatter.Deserialize (System.IO.Stream serializationStream) [0x00000] at System.Runtime.Remoting.Channels.CADSerializer.DeserializeObject (System.IO.MemoryStream mem) [0x00000] at System.Runtime.Remoting.RemotingServices.GetDomainProxy (System.AppDomain domain) [0x00000] at System.AppDomain.CreateDomain (System.String friendlyName, System.Security.Policy.Evidence securityInfo, System.AppDomainSetup info) [0x00000] at System.Web.Hosting.ApplicationHost.CreateApplicationHost (System.Type hostType, System.String virtualDir, System.String physicalDir) [0x00000] at Mono.WebServer.VPathToHost.CreateHost (Mono.WebServer.ApplicationServer server, Mono.WebServer.WebSource webSource) [0x00000] at Mono.WebServer.ApplicationServer.GetApplicationForPath (System.String vhost, Int32 port, System.String path, Boolean defaultToRoot) [0x00000] at (wrapper remoting-invoke-with-check) Mono.WebServer.ApplicationServer:GetApplicationForPath (string,int,string,bool) at Mono.WebServer.ModMonoWorker.GetOrCreateApplication (System.String vhost, Int32 port, System.String filepath, System.String virt) [0x00000] at Mono.WebServer.ModMonoWorker.InnerRun (System.Object state) [0x00000] at Mono.WebServer.ModMonoWorker.Run (System.Object state) [0x00000] [Tue Apr 20 03:10:26 2010] [error] (70014)End of file found: read_data failed [Tue Apr 20 03:10:26 2010] [error] Command stream corrupted, last command was -1 Along with the above errors, Apache's error.log is packed with hundreds (if not thousands) of the following error: Maximum number (20) of concurrent mod_mono requests to /tmp/mod_mono_dashboard_default_2.lock reached.

This tab shows you the local file system associated with the instance and any shared storage libraries mounted by Ops Center. More detailed information about file system storage is available under the Analytics tab under the sub-tab named Charts. Here, you can select and display the individual mount points of an OS, and export the utilization data if desired: In this example, the OS instance has a basic root file partition and several NFS directories. Each file system mount point can be independently chosen for display in the Ops Center chart. File Systems and Incident  Reporting Every asset managed by Ops Center has a "monitoring policy", which determines what represents a reportable issue with the asset. The policy is made up of a bunch of monitoring rules, where each rule describes An attribute to monitor The conditions which represent an issue The level or levels of severity for the issue When the conditions are met, Ops Center sends a notification and creates an incident. By default, OS instances have three monitoring rules associated with file systems: File System Reachability: Triggers an incident if a file system is not reachable NAS Library Status: Triggers an incident for a value of "WARNING" or "DEGRADED" for a NAS-based file system File System Used Space Percentage: Triggers an incident when file system utilization grows beyond defined thresholds You can view these rules in the Monitoring tab for an OS: Of course, the default monitoring rules is that they apply to every file system associated with an OS instance. As a result, any issue with NAS accessibility or disk utilization will trigger an incident. This can cause incidents for file systems to be reported multiple times if the same shared storage is used by many assets, as shown in this screen shot: Depending on the level of control you'd like, there are a number of ways to fine tune incident reporting. Note that any changes to an asset's monitoring policy will detach it from the default, creating a new monitoring policy for the asset. If you'd like, you can extract a monitoring policy from an asset, which allows you to save it and apply the customized monitoring profile to other OS assets. Solution #1: Modify the Reporting Thresholds In some cases, you may want to modify the basic conditions for incident reporting in your file system. The changes you make to a default monitoring rule will apply to all of the file systems associated with your operating system. Selecting the File Systems Used Space Percentage entry and clicking the "Edit Alert Monitoring Rule Parameters" button opens a pop-up dialog which allows you to modify the rule. The first screen lets you decide when you will check for file system usage, and how long you will wait before opening an incident in Ops Center. By default, Ops Center monitors continuously and reports disk utilization issues which exist for more than 15 minutes. The second screen lets you define actual threshold values. By default, Ops Center opens a Warning level incident is utilization rises above 80%, and a Critical level incident for utilization above 95% Solution #2: Disable Incident Reporting for File System If you'd rather not report file system incidents, you can disable the monitoring rules altogether. In this case, you can select the monitoring rules and click the "Disable Alert Monitoring Rule(s)" button to open the pop-up confirmation dialog. Like the first solution, this option affects all file system monitoring. It allows you to completely disable incident reporting for NAS library status or file system space consumption. Solution #3: Create New Monitoring Rules for Specific File Systems If you'd like to have the greatest flexibility when monitoring file systems, you can create entirely new rules. Clicking the "Add Alert Monitoring Rule" (the icon with the green plus sign) opens a wizard which allows you to define a new rule.  This rule will be based on a threshold, and will be used to monitor operating system assets. We'd like to add a rule to track disk utilization for a specific file system - the /nfs-guest directory. To do this, we specify the following attribute FileSystemUsages.name=/nfs-guest.usedSpacePercentage The value of name in the attribute allows us to define a specific NFS shared directory or file system... in the case of this OS, we could have chosen any of the values shown in the File Systems Utilization chart at the beginning of this article. usedSpacePercentage lets us define a threshold based on the percentage of total disk space used. There are a number of other values that we could use for threshold-based monitoring of FileSystemUsages, including freeSpace freeSpacePercentage totalSpace usedSpace usedSpacePercentage The final sections of the screen allow us to determine when to monitor for disk usage, and how long to wait after utilization reaches a threshold before creating an incident. The next screen lets us define the threshold values and severity levels for the monitoring rule: If historical data is available, Ops Center will display it in the screen. Clicking the Apply button will create the new monitoring rule and active it in your monitoring policy. If you combine this with one of the previous solutions, you can precisely define which file systems will generate incidents and notifications. For example, this monitoring policy has the default "File System Used Space Percentage" rule disabled, but the new rule reports ONLY on utilization for the /nfs-guest directory.

It's only happening on this server, on any of the app pools on the server (not confined to this one) and an app pool restart sorts it. Any help much appreciated. Cheers, Matthew

  • C# Gui setting control.Enabled to false fires OnClick event???

    - by Daniel
    For some really weird reason when i set the .Enabled property to false on a simple text box on a small GUI, it fires a radio buttons OnClick event and its causing lots of problems. I have breakpointed the txtBox.Enabled = false; and after stepping over OR into it i jump straight to the OnClick event of the radio button control Here is the call stack as that happened: TestGUI.exe!TestGUI.frmMain.radiobuttonClicked(object sender = {Text = "Download Single Episode" Checked = true}, System.EventArgs e = {System.EventArgs}) Line 67 C# System.Windows.Forms.dll!System.Windows.Forms.Control.OnClick(System.EventArgs e) + 0x70 bytes System.Windows.Forms.dll!System.Windows.Forms.RadioButton.OnClick(System.EventArgs e) + 0x27 bytes System.Windows.Forms.dll!System.Windows.Forms.RadioButton.OnEnter(System.EventArgs e = {System.EventArgs}) + 0x3e bytes System.Windows.Forms.dll!System.Windows.Forms.Control.NotifyEnter() + 0x20 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.UpdateFocusedControl() + 0x195 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.AssignActiveControlInternal(System.Windows.Forms.Control value = {Text = "Download Single Episode" Checked = true}) + 0x54 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.ActivateControlInternal(System.Windows.Forms.Control control, bool originator = false) + 0x76 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.SetActiveControlInternal(System.Windows.Forms.Control value = {Text = "Download Single Episode" Checked = true}) + 0x73 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.SetActiveControl(System.Windows.Forms.Control ctl) + 0x33 bytes System.Windows.Forms.dll!System.Windows.Forms.ContainerControl.ActiveControl.set(System.Windows.Forms.Control value) + 0x5 bytes System.Windows.Forms.dll!System.Windows.Forms.Control.Select(bool directed, bool forward) + 0x1b bytes System.Windows.Forms.dll!System.Windows.Forms.Control.SelectNextControl(System.Windows.Forms.Control ctl, bool forward, bool tabStopOnly, bool nested, bool wrap) + 0x7b bytes System.Windows.Forms.dll!System.Windows.Forms.Control.SelectNextControlInternal(System.Windows.Forms.Control ctl, bool forward, bool tabStopOnly, bool nested, bool wrap) + 0x4a bytes System.Windows.Forms.dll!System.Windows.Forms.Control.SelectNextIfFocused() + 0x61 bytes System.Windows.Forms.dll!System.Windows.Forms.Control.Enabled.set(bool value) + 0x42 bytes What the hell?

  • The Red Gate Guide to SQL Server Team based Development Free e-book

    - by Mladen Prajdic
    After about 6 months of work, the new book I've coauthored with Grant Fritchey (Blog|Twitter), Phil Factor (Blog|Twitter) and Alex Kuznetsov (Blog|Twitter) is out. They're all smart folks I talk to online and this book is packed with good ideas backed by years of experience. The book contains a good deal of information about things you need to think of when doing any kind of multi person database development. Although it's meant for SQL Server, the principles can be applied to any database platform out there. In the book you will find information on: writing readable code, documenting code, source control and change management, deploying code between environments, unit testing, reusing code, searching and refactoring your code base. I've written chapter 5 about Database testing and chapter 11 about SQL Refactoring. In the database testing chapter (chapter 5) I cover why you should test your database, why it is a good idea to have a database access interface composed of stored procedures, views and user defined functions, what and how to test. I talk about how there are many testing methods like black and white box testing, unit and integration testing, error and stress testing and why and how you should do all those. Sometimes you have to convince management to go for testing in the development lifecycle so I give some pointers and tips how to do that. Testing databases is a bit different from testing object oriented code in a way that to have independent unit tests you need to rollback your code after each test. The chapter shows you ways to do this and also how to avoid it. At the end I show how to test various database objects and how to test access to them. In the SQL Refactoring chapter (chapter 11) I cover why refactor and where to even begin refactoring. I also who you a way to achieve a set based mindset to solve SQL problems which is crucial to good SQL set based programming and a few commonly seen problems to refactor. These problems include: using functions on columns in the where clause, SELECT * problems, long stored procedure with many input parameters, one subquery per condition in the select statement, cursors are good for anything problem, using too large data types everywhere and using your data in code for business logic anti-pattern. You can read more about it and download it here: The Red Gate Guide to SQL Server Team-based Development Hope you like it and send me feedback if you wish too.

  • use networkmanager without system tray

    - by Yaakov Belch
    I use the minimal "fast lightweight window manager" (fwlm) which doesn't have a system tray. I need a simple program to manage my WIFI and virtual private netwok connection --- and found the NetworkManager. The problem is that the NetworkManager is a system-tray icon: I cannot see it or click on it in my fwlm windows manager. Hence, I ask: Is there any way to start the NetworkManager directly without using the system tray?

  • Connect Team Foundation Service/TFS 2012 with Visual Studio 2010 &amp; Visual Studio 2008

    - by Vishal
    Hello, Microsoft finally released the Team Foundation Service in late October 2012 after its long time in the preview phase. I was already using the TFS Preview which was free but I was happy to see Microsoft releasing the Team Foundation Service also FREE for upto 5 users. Isn't that great news? I know there are bunch of other free source control repositories (Github, Bitbucket, SVN etc.) out there but I somehow like TFS better. Also the other good thing about the final release was that I didn’t had to do any kind of migration of my code from preview to final release version. Just changed the TFS connection URL and it worked like a charm. Anyways, if you are a startup with small team and need some awesome Source Control along with all the good Project Management, Continuous Integration (Build, Test, Deploy), Team Collaboration, Agile/Scrum planning etc. features than Team Foundation Service is your answer. Microsoft has not yet released their pricing for more than 5 users and will be releasing it sometime in early 2013. What if as of now you have a team more than 5 users and you want to use Team Foundation Service, the good news is you can use it for FREE but when they release the final pricing, you will have to transition to the paid plan. Lot of story, getting to the point, connecting to Team Foundation Service with Visual Studio 2012 is straight forward and would work out of the box but it wont for previous versions of Visual Studio. You will have to upgrade to the latest service pack first and than install the forward compatibility pack. (1st : Service Packs & 2nd: Forward Compatibility packs) For Visual Studio 2010: Visual Studio 2010 Service Pack 1. Visual Studio 2010 forward compatibility for TFS 2012 and Team Foundation Service.         For Visual Studio 2008: Visual Studio 2008 Service Pack 1. Visual Studio 2008 forward compatibility for TFS 2012 & Team Foundation Service. Restart your system. Visual Studio 2008 will not work if you only put https://xxx.visualstudio.com. You will have to put your collection name too as shown below.       By the way, it doesn’t matter if you are an Apple Application Developer or Android App Developer, you can still use Team Foundation Service as your source control. Below are few links to connect to Team Foundation Service with other IDEs: Connect Eclipse to Team Foundation Service. Connect XCode to Team Foundation Service. Happy coding. Vishal Mody

Please note that I am not referring to bug fixing support, I am referring to the broader OS support, with people available to engage users needing support with a problem and drive it to a proper resolution. Is there an official team for this purpose with a clear scope and activity plan ?

  • How to effectively use an overseas SEO team?

    - by Dan Gayle
    My company is currently in contract with a 20+ person team in the Philippines, previously used for comment linking and guest blogging spun content articles. This is a practice that we're stopping, but we don't want to sever our team because they work hard, they're really cheap, and they produce excellent accounting and reporting of their actions. What are ways that we can best put them to use as a link generating or content generating resource? Their English is fair, but not of high enough quality to use them for any direct content creation. Thanks

  • Shared block device file system (cluster file system without networking)

    - by fungs
    Is there any file system that can be mounted multiple times and supports concurrent file access for Linux? Basically I want something like a cluster file system but without the need to have a running network for a distributed lock manager. That can be very handy in connection with virtual machines that can share data with the host or another VM without the need to create a network link. This I want to avoid to keep the network architecture secure (virtual machine in DMZ) but share large files. No need to scale it up, just two machines that mount the same block device. Shouldn't it be possible to have file locking information right on the disk?
