  • Is the Subversion 'stack' a realistic alternative to Team Foundation Server?

    - by Robert S.
    I'm evaluating Microsoft Team Foundation Server for my customer, who currently uses Visual SourceSafe and nothing else. They have explicitly expressed a desire to implement a more rigid and process-driven environment as their application is in production and they have future releases to consider. The particular areas I'm trying to cover are: Configuration management (e.g., source control) Change management (workflow and doco for change requests, tasks) Release management (builds and deployments) Incident and problem management (issues and bugs) Document management (similar to source control, but available via web) Code analysis constraints on check-ins A testing framework Reporting Visual Studio 2008 integration TFS does all of these things quite well, but it's expensive and complex to maintain, and the inexpensive Workgroup edition doesn't scale. We don't get TFS as part of our MSDN subscription. Those problems can be overcome, but before I tell my customer to go the TFS route, which in itself isn't a terrible thing, I wanted to evaluate the alternatives. I know Subversion is often suggested for its configuration management/source control, but what about the other areas? Would a combination of Subversion/NUnit/Wiki/CruiseControl/NAnt/something else satisfy all of these requirements? What tools do I need to include in my evaluation? Or should I just bite the bullet and go with TFS since we're already invested in the Microsoft stack?

  • How do I make use of multiple cores in Large SQL Server Queries?

    - by Jonathan Beerhalter
    I have two SQL Servers, one for production, and one as an archive. Every night, we've got a SQL job that runs and copies the days production data over to the archive. As we've grown, this process takes longer and longer and longer. When I watch the utilization on the archive server running the archival process, I see that it only ever makes use of a single core. And since this box has eight cores, this is a huge waste of resources. The job runs at 3AM, so it's free to take any and all resources it can find. So what I need to do if figure out how to structure SQL Server jobs so they can take advantage of multiple cores, but I can't find any literature on tackling this problem. We're running SQL Server 2005, but I could certainly push for an upgrade if 2008 takes of this problem.

  • WCF - Return object without serializing?

    - by Mayo
    One of my WCF functions returns an object that has a member variable of a type from another library that is beyond my control. I cannot decorate that library's classes. In fact, I cannot even use DataContractSurrogate because the library's classes have private member variables that are essential to operation (i.e. if I return the object without those private member variables, the public properties throw exceptions). If I say that interoperability for this particular method is not needed (at least until the owners of this library can revise to make their objects serializable), is it possible for me to use WCF to return this object such that it can at least be consumed by a .NET client? How do I go about doing that? Update: I am adding pseudo code below... // My code, I have control [DataContract] public class MyObject { private TheirObject theirObject; [DataMember] public int SomeNumber { get { return theirObject.SomeNumber; } // public property exposed private set { } } } // Their code, I have no control public class TheirObject { private TheirOtherObject theirOtherObject; public int SomeNumber { get { return theirOtherObject.SomeOtherProperty; } set { // ... } } } I've tried adding DataMember to my instance of their object, making it public, using a DataContractSurrogate, and even manually streaming the object. In all cases, I get some error that eventually leads back to their object not being explicitly serializable.

  • Why Does TFS Allow Orphaned Content and How Do I Get Rid of It?

    - by Chad
    My TfsVersionControl database has grown to 40+ GB in size. We recently did a TFS Destroy on a folder tree that should have cleared up at least 10 GB but instead it seemed to have no effect. When I look at the tables in TfsVersionControl, I am first shocked to see that there are no foreign keys at all in the database. Running a few queries, I see that there is some orphaning going on: tbl_Content has 13.9 GB of records that don't have a related tbl_File record tbl_File and tbl_Content have 2.4 GB that don't have a related tbl_Namespace record The cleanup job seems to be running nightly (prc_DeleteUnusedContent) and running it against the database manually doesn't remove any orphans. I see in the log for the cleanup job that it failed on 3/16, which is the morning after I destroyed the large amount of data. The error was due to a full transaction log. Could that error be the reason I'm left with all this orphaned data that can't be deleted? How can I permanently destroy this unneeded content?

  • How to load modules in Java

    - by gerardorn
    I'm building a server that loads modules. Each module is a .jar file. Inside the jar there's all the classes that the module needs. The server needs to read the jar, find the main class (it doesnt have the main method on it is just the class that makes the module work but not as a different program), build an object of that class and store it in a vector of modules so that it can acces to a specific module depending on the job to be done. How can I do that? As far as the server, it is listening and receiving request, but there's no modules to delegate the job to, since my vector of modules is empty.

  • Windows Form UserControl design time properties

    - by Raffaeu
    I am struggling with a UserControl. I have a UserControl that represent a Pager and it has a Presenter object property exposed in this way: [Browsable(false)] [DesignSerializationAttribute(DesignSerializationAttribute.Hidden)] public object Presenter { get; set; } The code itself works as I can drag and drop a control into a Windows From without having Visual Studio initializing this property. Now, because in the Load event of this control I call a method of the Presenter that at run-time is null ... I have introduced this additional code: public override void OnLoad(...) { if (this.DesignMode) { base.OnLoad(e); return; } presenter.OnViewReady(); } Now, every time I open a Window that contains this UserControl, Visual Studio modifies the Windows designer code. So, as soon as I open it, VS ask me if I want to save it ... and of course, if I add a control to the Window, it doesn't keep the changes ... As soon as I remove the UserControl Pager the problem disappears ... How should I tackle that in the proper way? I just don't want that the presenter property is initialized at design time as it is injected at runtime ...

  • Best practice: How to persist simple data without a database in django?

    - by Infinity
    I'm building a website that doesn't require a database because a REST API "is the database". (Except you don't want to be putting site-specific things in there, since the API is used by mostly mobile clients) However there's a few things that normally would be put in a database, for example the "jobs" page. You have master list view, and the detail views for each job, and it should be easy to add new job entries. (not necessarily via a CMS, but that would be awesome) e.g. example.com/careers/ and example.com/careers/77/ I could just hardcode this stuff in templates, but that's no DRY- you have to update the master template and the detail template every time. What do you guys think? Maybe a YAML file? Or any better ideas? Thx

  • Making A Dynaically Created Excel Report Downloadable

    - by Nick LaMarca
    I have 2 blocks of code, if someone could help me put them together I would get the functionality I am looking for. The first block of code downloads a gridview to excel using the download dialog I am looking for: Public Overloads Overrides Sub VerifyRenderingInServerForm(ByVal control As Control) ' Verifies that the control is rendered End Sub Private Sub ExportToExcel(ByVal filename As String, ByVal gv As GridView, ByVal numOfCol As Integer) Response.Clear() Response.Buffer = True Response.AddHeader("content-disposition", String.Format("attachment; filename={0}", filename)) Response.Charset = "" Response.ContentType = "application/vnd.ms-excel" Dim sw As New StringWriter() Dim hw As New HtmlTextWriter(sw) gv.AllowPaging = False gv.DataBind() 'Change the Header Row back to white color gv.HeaderRow.Style.Add("background-color", "#FFFFFF") For i As Integer = 0 To numOfCol - 1 gv.HeaderRow.Cells(i).Style.Add("background-color", "blue") gv.HeaderRow.Cells(i).Style.Add("color", "#FFFFFF") Next For i As Integer = 0 To gv.Rows.Count - 1 Dim row As GridViewRow = gv.Rows(i) 'Change Color back to white row.BackColor = System.Drawing.Color.White For j As Integer = 0 To numOfCol - 1 row.Cells(j).Style.Add("text-align", "center") Next 'Apply text style to each Row row.Attributes.Add("class", "textmode") 'Apply style to Individual Cells of Alternating Row If i Mod 2 <> 0 Then For j As Integer = 0 To numOfCol - 1 row.Cells(j).Style.Add("background-color", "#CCFFFF") row.Cells(j).Style.Add("text-align", "center") '#C2D69B 'row.Cells(j).Style.Add("font-size", "12pt") Next End If Next gv.RenderControl(hw) 'style to format numbers to string Dim style As String = "<style> .textmode { mso-number-format:\@; } </style>" Response.Write(style) Response.Output.Write(sw.ToString()) Response.Flush() Response.End() End Sub The second block of code is a sample report I am wish to be downloaded. So instead of downloading a gridview I want this function to accept a worksheet object.

  • jquery asp.net combo box question

    - by coson
    Good Day, I have a small form with a combo box (ASP.NET Drop Down List control) and a text box (with a DIV id txtName). When the selected index of the combo box changes, I want to clear out the text box. I understand that: $("#txtName").val(''); clears the text box value The thing is the combo box. It contains a list of integers representing the months of the year. The drop down control is called ddlMonths. $("#ddlMonths").change(function() { $("#txtName").val(''); }); I thought by using change, an onSelectedIndexChange event handler would be associated with this control. I also tried (because I've ran into the client id being mangled in ASP.NET w/ jQuery) this: $("#<%=ddlMonths.ClientID%>").change(function() { $("#<%=txtName.ClientID%>").val(''); }); and neither approach seems to be working. Am I missing something? TIA, coson

  • asp.net - updatepannel can't read innerHTML?

    - by omega
    In my asp.net page, I have a jquery sortable accordian (in an update panel) I use so that clients can re-arrange items. Then to save it, users would click a button (thats created from jquery) and it would traverse through the accoridion in the DOM, and write the info to a asp control textbox. Then invoke the click function of a asp button control, which then reads that information and saves the data. But now I decided to simplify this step, and use html agility pack in c#, so users click the asp button control (inside an update panel), and then it would get the innerHTML of the accordian. But the problem is, the html it's getting is not the reflecting the changes a user can make to the accordion (i.e. re arranging it), it the same as when the DOM was ready on page load... But note that, using javascript to write the innerHTML to a textbox, then from the c# function, I can read the up to date html from the accordian. Does anyone know why this is happening and how to get the up to data html from the accordian in c#?

  • hadoop - large database query

    - by Mastergeek
    Situation: I have a Postgres DB that contains a table with several million rows and I'm trying to query all of those rows for a MapReduce job. From the research I've done on DBInputFormat, Hadoop might try and use the same query again for a new mapper and since these queries take a considerable amount of time I'd like to prevent this in one of two ways that I've thought up: 1) Limit the job to only run 1 mapper that queries the whole table and call it good. or 2) Somehow incorporate an offset in the query so that if Hadoop does try to use a new mapper it won't grab the same stuff. I feel like option (1) seems more promising, but I don't know if such a configuration is possible. Option(2) sounds nice in theory but I have no idea how I would keep track of the mappers being made and if it is at all possible to detect that and reconfigure. Help is appreciated and I'm namely looking for a way to pull all of the DB table data and not have several of the same query running because that would be a waste of time.

  • .NET MVC What is the best way to disable browser caching?

    - by Chameera Dedduwage
    As far as my research goes, there are several steps in order to make sure that browser caching is disabled. These HTTP headers must be set: Cache-Control: no-cache, no-store, must-revalidate, proxy-revalidate Pragma: no-cache, no-store Expires: -1 Last-Modified: -1 I have found out that this can be done in two ways: Way One: use the web.config file <add name="Cache-Control" value="no-store, no-cache, must-revalidate, proxy-revalidate"/> <add name="Pragma" value="no-cache, no-store" /> <add name="Expires" value="-1" /> <add name="Last-Modified" value="-1" /> Way Two: use the meta tags in _Layout.cshtml <meta http-equiv="Cache-Control" content="no-cache, no-store, must-revalidate, proxy-revalidate" /> <meta http-equiv="Pragma" content="no-cache, no-store" /> <meta http-equiv="Expires" content="-1" /> <meta http-equiv="Expires" content="-1" /> My Question: which is the better approach? Or, alternatively, are they equally acceptable? How do these all relate to different platforms? Which browsers would honor what headers? In addition, please feel free to add anything I've missed, if any.

  • What is corresponding Cron expression to fire in every X seconds, where X > 60?

    - by giolekva
    I want my jobs to execute in every X seconds, there's one to one matching between job and X. Also during runtime there can be registered new jobs with their own intervals. I've tried to write cron expression for such scenarios, but in documentation there's written that value of seconds can't be more than 69. So cron expression like this: "0/63 * * * * ?" isn't valid. At first sight solution of that problem seemed to be expression like this: "0/3 0/1 * * * ?", but it means completely different thing: trigger job in every three second of every minute. Can you suggest what is the right solution (cron expression) for that? I know I could use just simple timers, but I've to use cron jobs using Quartz.

  • Did you ever switch from one programming language to another?

    - by Johan Pelgrim
    The stereotypical programmer is very keen on writing software in one particular programming language and is very fanatic about defending their programming language in any way they can, without being realistic about whether their programming language is the best tool for the job. The other kind of programmer can take a step back and switch between languages (or is not very concerned about doing everything in just one language), is a "jack-of-all-trades", and doesn't mind learning a new language as long as it solves their problem in a good fashion. Did you ever switch from one programming language to another? If yes, why? [P.S. Please don't just answer with "I switched from language A to B because company X sucks! I think it will be very useful to understand why people switch between languages, or what's the best tool for a particular kind of job]

  • SQL compare entire rows

    - by zmaster
    In SQL server 2008 I have some huge tables (200-300+ cols). Every day we run a batch job generating a new table with timestamp appended to the name of the table. The the tables have no PK. I would like a generic way to compare 2 rows from two tables. Showing which cols having different values is sufficient, but showing the values would be perfect. Thanks a lot Thanks for the answers. I ended up writing my own C# tool to do the job - as Im not allowed to install 3rd party software in my company.

    I have a java server application that, when its running, you can interact with it sending commands via stdin. I want to write a web interface that can send these commands to it. In order to do that I need some way of getting commands from php to the stdin for this backgrounded job. Is there a way to do this from console? or possibly write some kind of wrapper that controls the server job and can access its stdin ? could this be done in python?

  • how to create english language dictionary application with python (django)?

    - by sintaloo
    Hi All, I would like to create an online dictionary application by using python (or with django). It will be similar to http://dictionary.reference.com/. My question is (1) Are there any existing open source python package or modules or application which implements this functionality that I can use or study from? (2) If the answer to the first question is NO. which algorithm should I follow to create such web application? Can I simply use the python built-in dictionary object for this job? so that the dictionary object's key will be the english word and the value will be the explanation. is this OK in term of performance? OR Do I have to create my own Tree Object to speed up the search? or any existing package which handles this job properly? Thank you very much.

  • For a 1view/scene to 2view/scene app, what application should I choose in Xcode?

    - by Tony Xu
    The question may be simple to some others, but I have been struggling with this for a while. The app I want would be like this: first scene/view with two big buttons (no toolbar item), click each one to get into two new scenes. So totally three scenes. In Xcode, what application should I choose? And in storyboard how/should I drag/draw? Thanks. Update: thanks for the link, the big-number-user. I actually read that tutorial before I asked. A little update on what I got so far: 1, I selected "single view", so there's view controller 1 (VC1) in the storyboard. 2, dragged a navigation controller (NC), and move the initial view arrow pointing to NC 3, control-drag to link NC and VC1, selected "relationship segue root view controller" when some small dialog popup. IS THIS CORRECT? 4, created two additional VC, VC3 and VC4, control-drag link each to NC. selected "push", IS THIS CORRECT? 5, in VC1, I added two buttons, showVC3 and showVC4. NOW I DON'T KNOW how to add IBAction to button showVC3 and showVC4. I tried to control-drag it to ViewController.m file @interface and @end section, but failed. What should I do next?

  • Looking for PyQt4 embeddable terminal widget

    - by redShadow
    I wrote an application that, among other things, launches some "backend" processes to do some stuff. These subprocesses are very likely to fail or have unexpected behavior since they have to operate in quite hard conditions, so I prefer to give full control over them to the operator. NOTE: I am running these processes using a subprocess module based class instead of QProcess to have some more control functionality over the running process. At the moment, I'm using a QPlainTextEdit widget to which I append standard output/error from the subprocess, plus some buttons to quickly send some common signals (INT, STOP, CONT, KILL, ..), but: In some cases it would be useful to send some input too. Although it could be done with a text input box, I would prefer using something more "professional" Of course, there is no direct way to interpret special control characters, such as color codes, cursor movement, etc.. I had to implement an auto-scroll management of the console, but it is not guaranteed 100% to work nicely (sometimes the scroll locking doesn't work as expected, etc.) So: does anyone know something I could use to accomplish these needs? I found qtermwidget but it seems more oriented on handling a shell process (and the Python bindings seems to let you run /bin/bash only) by itself than communicating with an already existing process I/O.

  • form validation with jquery and livevalidation

    - by ImpY
    I'm trying to do some form validation with livevaldation & jquery. I've a formular with an input field like that: <div id="prenameDiv" class="control-group"> `<input id="prename" name="prename" class="input-large" placeholder="Max" >` </div> So if there's an error on validation 'livevalidaton' adds the class 'LV_invalid_field' to the input - it looks like that: <div id="prenameDiv" class="control-group"> <input id="prename" name="prename" class="input-large LV_invalid_field" placeholder="Max" > </div> That's ok, but now I'll add another class 'error' to the div 'prenameDiv' when the DOM changes that it looks like that: <div id="prenameDiv" class="control-group error"> `<input id="prename" name="prename" class="input-large LV_invalid_field" placeholder="Max" ` </div> I tried it that way: if ($("#prenameDiv").bind("DOMSubtreeModified")){ `if ($("#prename").hasClass("LV_invalid_field")) {` $("#prenameDiv").addClass("error"); } } But nothing changes? Do you have some ideas?
