  • Which places I could question about TFS, Visual Studio and ALM?

    - by afsharm
    Hi all, We are going to applying VSTS 2010 in our company. This includes Visual Studio, TFS, TFS Build and ALM. It's predictable that we would encounter a wave of new questions about their usage. But the problem is I don't know which places we could do questioning. StackOverflow is programming base question site and ServerFault is not very active. How do you think about? Which places and their advantages and disadvantages? afsharm

  • How do I pipe the Java console output to a file?

    - by Ced
    I found a bug in an application that completely freezes the JVM. The produced stacktrace would provide valuable information for the developers and I would like to retrieve it from the Java console. When the JVM crashes, the console is frozen and I cannot copy the contained text anymore. Is there way to pipe the Java console directly to a file or some other means of accessing the console output of a Java application? Update: I forgot to mention, without changing the code. I am a manual tester. Update 2: This is under Windows XP and it's actually a web start application. Piping the output of javaws jnlp-url does not work (empty file).

  • Outlook Macro not executing

    - by Tim
    Hello all, we are using an an outlook macro for incoming emails to unzip the attachments, log them in sql server and copy them to a special working folder where a windows service processes them. The problems are: the user must be logged in at the server otherwise the macro wont run. I think there is no workaround for this. whenever a modal dialog pops up in outlook and waits for user input, the macro wont execute either (f.e. AutoArchive) I have stopped AutoArchiving all x-days in the options. Because its a productive environment, are there other possible windows preventing the macro to execute, which i must disable now? Our outlook-macro solution surely is not the best because of above problems. Are there better alternatives to read emails, unzip attachments and move them to a working folder? My language is VB.Net and server OS is windows 2008. Regards, Tim

  • Understanding pattern matching with cons operator

    - by Mathias
    In "Programming F#" I came across a pattern-matching like this one (I simplified a bit): let rec len list = match list with | [] -> 0 | [_] -> 1 | head :: tail -> 1 + len tail;; Practically, I understand that the last match recognizes the head and tail of the list. Conceptually, I don't get why it works. As far as I understand, :: is the cons operator, which appends a value in head position of a list, but it doesn't look to me like it is being used as an operator here. Should I understand this as a "special syntax" for lists, where :: is interpreted as an operator or a "match pattern" depending on context? Or can the same idea be extended for types other than lists, with other operators?

  • What are the Hot and Cold observables?

    - by Sergey Aldoukhov
    I watched the video and I know the general principles - hot happens even when nobody is subscribed, cold happens "on demand". Also, Publish() converts cold to hot and Defer() converts hot to cold. But still, I feel I am missing the details. Here are some questions I'd like to have answered: Can you give a comprehensive definition for these terms? Does it ever make sense to call Publish on hot observable or Defer on cold? Is there differences between hot and cold definitions for IObservable and IEnumerable? What are the general principles you should take into account when programming for cold or hot? Any other tips on hot/cold observables?

  • Deliberately adding bugs to assess QA processes

    - by bgbg
    How do you know that as many bugs as possiblle have been discovered and solved in a program? Couple of years ago I have read a document about debugging (I think it was some sort of HOWTO). Among other things, that document described a technique in which the programming team deliberately adds bugs into the code and passes it to the QA team. The QA process is considered completed when all the deliberately known bugs have been discovered. Unfortunately, I cannot find this document, or any similar one with description of this trick. Can someone please point me to such a document?

  • Jagged Array Dimensions

    - by Soo
    I'm using jagged arrays and have a bit of a problem (or at least I think I do). The size of these arrays are determined by how many rows are returned in a database, so it is very variable. The only solution I have is to set the dimensions of the array to be very huge, but this seems ... just not the best way to do things. int[][] hulkSmash = new int[10][]; hulkSmash[0] = new int[2] {1,2}; How can I work with jagged arrays without setting the dimensions, or is this just a fact of life with C# programming??

  • LINQ-to-SQL and SQL Compact - database file sharing problem

    - by Eye of Hell
    Hello. I'm learing LINQ-to-SQL right now and i have wrote a simple application that define SQL data: [Table( Name = "items" )] public class Item { [ Column( IsPrimaryKey = true, IsDbGenerated = true ) ] public int Id; [ Column ] public string Name; } I have launched 2 copy of application connected to the same .sdf file and tested if all database modifications in one application affects another application. But strange thing arise. If i use InsertOnSubmit() and DeleteOnSubmit() in one application, added/removed items are instantly visible in other application via 'select' LINQ queue. But if i try to modify 'Name' field in one application, it is NOT visible in other applicaton until it reconnects the database :(. The test code i use: var Items = from c in db.Items where Id == c.Id select c; foreach( var Item in Items ) { Item.Name = "new name"; break; } db.SubmitChanges(); Can anyone suggest what i'm doing wrong and why InsertOnSubmit()/DeleteOnSubmit works and SubmitChanges() don't?

  • Query size of block device file in Python

    - by ??O?????
    Hello. I have a Python script that reads a file (typically from optical media) marking the unreadable sectors, to allow a re-attempt to read said unreadable sectors on a different optical reader. I discovered that my script does not work with block devices (e.g. /dev/sr0), in order to create a copy of the contained ISO9660/UDF filesystem, because os.stat().st_size is zero. The algorithm currently needs to know the filesize in advance; I can change that, but the issue (of knowing the block device size) remains, and it's not answered here, so I open this question. I am aware of the following two related SO questions: Determine the size of a block device (/proc/partitions, ioctl through ctypes) how to check file size in python? (about non-special files) Therefore, I'm asking: in Python, how can I get the file size of a block device file?

  • How do you energize yourself when working alone on a project?

    - by Stephane
    I am working in an environment with a very small team (3 developers only) and each of us have been assigned a different project, without counting support tasks. I know this is a bad business practice and that we should all work on a single project at a time, and then move on to the next one (Already explained to the management on how much it sucks). So don't answer me that we should work all together on one project at a time. Energizing the work when in a team is mostly pair programming we did that when less project were thrown at us and that was great. What I would like to know is how you energize your work when working alone on a project. Do you follow any particular practice?

  • Setting up Subsonic 3.0 on a ASP.NET web application on Visual Studio 2008

    - by Rob Paul
    I followed the steps on this tutorial video by at subsonic website. Everything seems to be self explanatory but when I copy the .tt files into my Visual Studio nothing happens. I have read other question relating to this problem on this website but they don't seem to fix this problem. I also went into the regedit to find out the generator key for .tt files and it is properly set. This is not a visual studio express or anything but a professional edition also I am trying to build a ASP.net web application and not a MVC application like the demo. Any help will be greatly appreciated. Thank You

  • Using injected EntityManager in class hierarchies

    - by Emre Sahin
    The following code works: @Stateless @LocalBean public class MyClass { @PersistenceContext(name = "MyPU") EntityManager em; public void myBusinessMethod(MyEntity e) { em.persist(e); } } But the following hierarchy gives a TransactionRequiredException in Glassfish 3.0 (and standard JPA annotations with EclipseLink.) at the line of persist. @Stateless @LocalBean public class MyClass extends MyBaseClass { public void myBusinessMethod(MyEntity e) { super.update(e); } } public abstract class MyBaseClass { @PersistenceContext(name = "MyPU") EntityManager em; public void update(Object e) { em.persist(e); } } For my EJB's I collected common code in an abstract class for cleaner code. (update also saves who did the operation and when, all my entities implement an interface.) This problem is not fatal, I can simply copy update and sister methods to subclasses but I would like to keep all of them together in a single place. I didn't try but this may be because my base class is abstract, but I would like to learn a proper method for such a (IMHO common) use case.

  • Update Nexus repository with local artifacts

    - by mamuesstack
    Hi, i recently downloaded some maven artifacts directly to my local repository (.m2/repository). Now i installed the Nexus Repository Manager and need to fill its storage without to download all the artifacts again. Is there a way to update the Nexus repository with the local one. I don't want to simply copy them because Nexus separate artifacts concerning their public servers (central, codehaus, etc.) and the local repository structure doesn't. Update: Meanwhile i copied the the artifacts from the local repository to the Nexus storage (public repository). I can browse to the artifacts via the Nexus webapp, but Maven somehow can't resolve the artifacts from Nexus. Do i need to register them particularly? I re-indexed the public repository and restarted Nexus multiple times - no changes.

  • I would like to convert Joomla CMS to ASP.net as there is no CMS like Joomla in .net. Would that

    - by SIA
    Hello friends I have this idea boggling my head since a long time. As a developer, I get a lot from the community and feel like giving back something to the community. And after knowing and working on Joomla i found Joomla CMS as the most flexible, easy and user friendly cms. As a developer, I like most of the features of it. Now, i want to have a asp.net version of joomla, available free to the community. I wanted to start it from scratch and it would be a copy/same as joomla. Would that be a good idea to go with it? Are there any CMS (same as Joomla) available in asp.net? I would like to have suggestions and advice from my community developers. Critics are welcomed ;) SIA

  • How Do I "open folder in explorer" in Netbeans PHP

    - by Hippyjim
    I'm attempting the conversion from Eclipse PDT to Netbeans PHP, and so far I'm really impressed. What would make things perfect is being able to open up a file structure in the standard windows explorer. Say I want to copy in a data file I've just tweaked in another app, or downloaded from a remote server, I have to navigate manually to the folder structure that I already have open in the IDE. It's just about the only thing from Eclipse that I miss in Netbeans. Any suggestions how I can reproduce the functionality?

  • How to find a programmer for my project?

    - by Al
    I'm building a web application to generate monthly subscription fees, but I've quickly realised I'm going to need some help with the project to finish it this century. I don't have any money upfront for a freelancer and every website I've found takes bids for project work. The tasks that need doing are flexible too because I can do whatever the other coder doesn't want to. I'm also happy to guide the developer and offer tips for performance/security/etc etc. My question is; how do I go about finding someone to work with on a profit-share basis? I'm sure there are a billion people like me with the "next killer app" but I genuinely believe in it. Can anyone offer some advice? Thanks in advance! EDIT: I guess the trick is to find someone passionate enough about the subject as I am. Where would I find someone? Are there websites that broker profit-share deals on programming work?

  • Using device variable by multiple threads on CUDA

    - by ashagi
    I am playing around with cuda. At the moment I have a problem. I am testing a large array for particular responses, and when I get the response, I have to copy the data onto another array. For example, my test array of 5 elements looks like this: [ ][ ][v1][ ][ ][v2] Result must look like this: [v1][v2] The problem is how do I calculate the address of the second array to store the result? All elements of the first array are checked in parallel. I am thinking to declare a device variable int addr = 0. Every time I find a response, I will increment the addr. But I am not sure about that because it means that addr may be accessed by multiple threads at the same time. Will that cause problems? Or will the thread wait until another thread finishes using that variable?

  • Sql Server copying table information between databases

    - by Andrew
    Hi, I have a script that I am using to copy data from a table in one database to a table in another database on the same Sql Server instance. The script works great when I am connected to the Sql Server instance as myself as I have dbo access to both databases. The problem is that this won't be the case on the client's Sql Server. They have seperate logins for each database (Sql Authentication Logins). Does anyone know if there is a way to run a script under these circumstances. The script would be doing something like. use sourceDB Insert targetDB.dbo.tblTest (id, test_name) Select id, test_name from dbo.tblTest Thanks

  • Overwriting arguments object for a Javascript function

    - by Ian Storm Taylor
    If I have the following: // Clean input. $.each(arguments, function(index, value) { arguments[index] = value.replace(/[\W\s]+/g, '').toLowerCase(); }); Would that be a bad thing to do? I have no further use for the uncleaned arguments in the function, and it would be nice not to create a useless copy of arguments just to use them, but are there any negative effects to doing this? Ideally I would have done this, but I'm guessing this runs into problems since arguments isn't really an Array: arguments = $.map(arguments, function(value) { return value.replace(/[\W\s]+/g, '').toLowerCase(); }); Thanks for any input. EDIT: I've just realized that both of these are now inside their own functions, so the arguments object has changed. Any way to do this without creating an unnecessary variable?

  • RSA Factorization problem

    - by dada
    At class we found this programming problem, and currently, we have no idea how to solve it. The positive integer n is given. It is known that n = p * q, where p and q are primes, p<=q and |q-k*p|<10^5 for some given positive integer k. You must find p and q. Input: 35 1 121 1 1000730021 9 Output: 5 * 7 11 * 11 10007 * 100003 It's not a homework, we are just trying to solve some interesting problems. If you have some ideas, please post them here so we can try something, thanks.

  • SQL select statement

    - by kwokwai
    Hi all, I got a Table which has two fields: Point, and Level, with some sample data as follows: ----------------------- Point | Level ----------------------- 10 | Level 1 20 | Level 2 30 | Level 3 40 | Level 4 Suppose that there is a user who has 25 points, to find the Level in which this user is in, the Select statement I used was: Select Level from Table where Point < 30 AND Point > 20; But the Select SQL ststament is a hard-copy one where you can see the ponts 30 and 20 are fixed. I want to alter the Select statement so that the new SQL Select statement can be applied to all users with different points, but I don't know how to do it.

  • SwingWorker in Java (beginner question)

    - by Malachi
    I am relatively new to multi-threading and want to execute a background task using a Swingworker thread - the method that is called does not actually return anything but I would like to be notified when it has completed. The code I have so far doesn't appear to be working: private void crawl(ActionEvent evt) { try { SwingWorker<Void, Void> crawler = new SwingWorker<Void, Void>() { @Override protected Void doInBackground() throws Exception { Discoverer discover = new Discoverer(); discover.crawl(); return null; } @Override protected void done() { JOptionPane.showMessageDialog(jfThis, "Finished Crawling", "Success", JOptionPane.INFORMATION_MESSAGE); } }; crawler.execute(); } catch (Exception ex) { JOptionPane.showMessageDialog(this, ex.getMessage(), "Exception", JOptionPane.ERROR_MESSAGE); } } Any feedback/advice would be greatly appreciated as multi-threading is a big area of programming that I am weak in.
