  • Should I fork for a major re-write that uses a small amount of the original code?

    - by It'sNotALie.
    I'm writing a library. It's a completely rewritten version of another one, to suit my needs (PCL compatibility, mainly). However, the API will be completely rewritten, as I'll need to change a lot of stuff around for PCL compliance. Also, as it is a rewrite, I won't be able to just start from the library and just change it bit by bit, as I typically see with forks. I tried that, but it just didn't work. So what should I do? Should I fork here or should I make a new library?

  • Are there any inline code validation libraries available for something similar to TryRuby.org or CodeSchool.com? [closed]

    - by Forkrul Assail
    Recently a lot of browser-based training sites have been spawned. These include tryruby.org, codeacademy.org, codeschool.org and the Udacity site uses something seemingly similar. They allow the user to type code in say Ruby or Python, this is then sent to the server and the output posted back to the browser. Are there libraries available for in-browser code validation? How would you approach this? Suggestions?

  • Should I use the ATI proprietary or free drivers with two Crossfire HD5850s?

    - by Dekel
    I own 2 XFX Radeon HD 5850 in crossfire configuration connected to 3 24" monitors. I really want to make Ubuntu my daily OS but can't seem to find the best configuration to use. Some threads say that the free driver is better then the ATI one and some say the new Catalyst fully takes advantage of the card capabilities. Anyone out there with a similar setup? What are your recommendations for a good production in 12.04 setup?

  • SQL Server 2012 Express LocalDB &ndash; How to get started

    - by krislankford
    As many of you aware, SQL Server can be a bit of a pig when it comes to system resources on your development machine. As part of the 2012 products Microsoft has added SQL Server 2012 Express LocalDB which is a happy medium for myself when thinking about having to install a full blown SQL Server on my box. This however does not work in all cases for all development but if you are doing web or local client development then it should suffice. On the other hand, if you are working with technologies like SharePoint or trying to run Team Foundation Server on your local box then you will be out of luck while using LocalDB. To start of with, the localDB setup is delivered and packaged with Visual Studio 2012 RC. If you want to get the stand-alone installer you can download it here in either the 32 or 64 bit flavors. Once you get it installed you can start using it right away in either Visual Studio 2010 or the new Visual Studio 2012 RC. To get started you can open the SQL Server object explorer in Visual Studio by clicking   the menu option View –> SQL Server Object Explorer. This will bring up to the navigation pane where you can add a SQL Server. Once you add the SQL Server you will be prompted with the “Connect to Server” dialog to enter the server for which you can use “(localdb)\v11.0”. Click connect and you should be connected to your localDB where you can create and manage databases from Visual Studio 2010, Visual Studio 2012 or SSMS. Once you have started creating databases here you can use the database projects in Visual Studio with these database as well as use the (localdb)\v11.0 server name inside your connections string information for your development environment. Hope this helps someone get started with SQL Server 2012 Express LocalDB! It provides a great balance for developing against SQL Server 2012.

  • Is this a typo in the Artistic License 2.0?

    - by IQAndreas
    I'm not sure if this would fit better in StackExchange/English, but regardless, there is no practical use to the answer, other than to cure my curiosity. Note this sentence at the end of the Artistic License 2.0: THE PACKAGE IS PROVIDED BY THE COPYRIGHT HOLDER AND CONTRIBUTORS "AS IS' AND WITHOUT ANY EXPRESS OR IMPLIED WARRANTIES. It does not affect any legal aspects of the license, but is there a reason they mixed the use of single and double quotes on AS IS? The license is so new that this wouldn't have been for "command prompt friendly" reasons. Is there special use or meaning behind this in the English language, or was it a typo?

  • How do you deal with monotony of certain tasks? [on hold]

    - by aaronmallen
    I love programming methods, and functions. The if {}, while {}, etc... logic behind them is so much fun. I also love making commits, merging branches, solving merge conflicts. Unfortunately these activities usually require that I create classes which I find tedious and monotonous. The simple action of defining properties, is getting in the way of me writing the logic on what to do with those properties. I can't be alone here there has to be a part of coding for everyone that they dread or at least severely dislike doing compared to other parts of coding. How do you deal with the code based tasks that you find tedious?

  • Extend linq-to-sql partial class to avoid writing a property?

    - by Curtis White
    I have a linq-to-sql class. I have a property "Password" for which I want to call the underlying ASP.NET Membership provider. Thus, I do not want this property written out directly but via my own code. I basically want to create a facade/proxy for this property such that I may use the underlying membership provider or a custom stored procedure. I want to accomplish without modifying the LINQ-TO-SQL designer generated code, if at all possible.

Currently most of the pivoting stuff am doing is by using T-SQL PIVOT which further get used in my SSIS package to merge with Dim table This pivoting can also be achieved by SSIS PIVOT Transformation component. In regards to Performance which approach would be the best? Thanks

  • SQL How to correctly set a date variable value and use it?

    - by flavour404
    Hi, I have the following query which uses a date variable, which is generated inside the stored procedure: DECLARE @sp_Date DATETIME SET @sp_Date = DateAdd(m, -6, GETDATE()) SELECT DISTINCT pat.PublicationID FROM PubAdvTransData AS pat INNER JOIN PubAdvertiser AS pa ON pat.AdvTransID = pa.AdvTransID WHERE (pat.LastAdDate > @sp_Date) AND (pa.AdvertiserID = 12345)) The problem is that the @sp_Date value appears to be being ignored and I am wondering why? Have I defined or used it incorrectly? sql microsoft sql-server-2008 User error... Thanks, R.

  • After writing SQL statements in MySQL, how to measure the speed / performance of them?

    - by Jian Lin
    I saw something from an "execution plan" article: 10 rows fetched in 0.0003s (0.7344s) How come there are 2 durations shown? What if I don't have large data set yet. For example, if I have only 20, 50, or even just 100 records, I can't really measure how faster 2 different SQL statements compare in term of speed in real life situation? In other words, there needs to be at least hundreds of thousands of records, or even a million records to accurately compares the performance of 2 different SQL statements?

  • How to insert a DataTable with existing Key to a SQL Server Table.

    - by user296575
    I am working with VB.NET.. i have a DataTable called "QUESTION", containing 3 fields: QuestionNumber (unique integer key) QuestionText QuestionType In my SQL Server database I created a Table called "QUESTION" with the same fields. QuestionNumber is defined as integer unique key, auto increment Now, when i make a bulk copy to insert the DataTable into the SQL Server, the database overwrites my QuestionNumber from the DataTable and generates new ones (starting from 1 increment 1). How do i have to change my database setup, that the original QuestionNumbers are copied into the database?

  • Using a Linq-To-SQL class automagically generates the connection string for me; is there a way to ma

    - by Sergio Tapia
    I'm just beginning to use Linq-to-SQL and it's just wonderful to use. The problem is, this software is going to be run on a lot of machines and each machine will have a unique connection string. Is there a way for me to manually set the connection the Linq-to-SQL (.dbml) uses? The way I'm doing things now is creating the .dbml file, and in the graphic designer I'm dragging tables from the Server Explorer to the white board of the .dbml.

  • If I can ping my DB server, is my SQL Server connection guaranteed to work?

    - by Matt
    If I can ping my DB server, is my SQL Server connection guaranteed to work? I am using a default connection string in my code. My program runs fine locally but overseas sites are having issues and I am wondering if SQL might be using a TCP or UDP port that is still blocked. Here is the connection string "Data Source=xxxx.xxxx.com; Initial Catalog = xxxxx; User ID=xxxxx;password=xxxxx"

  • Need to remotely create an ODBC connection to a SQl server.

    - by kris
    I have an Access 2007 database with a table in it that is linked to a SQL server. I need to roll this version of the database out to approximately 10 people in different states. In order to do that, they need an ODBC connection to the SQL server installed on their machines. I am looking for a way to do this remotely. Either through VBA in the database itself or perhaps a Batch file linked to their shortcut....I am open to ideas....

  • Under what circumstances would a LINQ-to-SQL Entity "lose" a changed field?

    - by John Rudy
    I'm going nuts over what should be a very simple situation. In an ASP.NET MVC 2 app (not that I think this matters), I have an edit action which takes a very small entity and makes a few changes. The key portion (outside of error handling/security) looks like this: Todo t = Repository.GetTodoByID(todoID); UpdateModel(t); Repository.Save(); Todo is the very simple, small entity with the following fields: ID (primary key), FolderID (foreign key), PercentComplete, TodoText, IsDeleted and SaleEffortID (foreign key). Each of these obviously corresponds to a field in the database. When UpdateModel(t) is called, t does get correctly updated for all fields which have changed. When Repository.Save() is called, by the time the SQL is written out, FolderID reverts back to its original value. The complete code to Repository.Save(): public void Save() { myDataContext.SubmitChanges(); } myDataContext is an instance of the DataContext class created by the LINQ-to-SQL designer. Nothing custom has been done to this aside from adding some common interfaces to some of the entities. I've validated that the FolderID is getting lost before the call to Repository.Save() by logging out the generated SQL: UPDATE [Todo].[TD_TODO] SET [TD_PercentComplete] = @p4, [TD_TodoText] = @p5, [TD_IsDeleted] = @p6 WHERE ([TD_ID] = @p0) AND ([TD_TDF_ID] = @p1) AND /* Folder ID */ ([TD_PercentComplete] = @p2) AND ([TD_TodoText] = @p3) AND (NOT ([TD_IsDeleted] = 1)) AND ([TD_SE_ID] IS NULL) /* SaleEffort ID */ -- @p0: Input BigInt (Size = -1; Prec = 0; Scale = 0) [5] -- @p1: Input BigInt (Size = -1; Prec = 0; Scale = 0) [1] /* this SHOULD be 4 and in the update list */ -- @p2: Input TinyInt (Size = -1; Prec = 0; Scale = 0) [90] -- @p3: Input NVarChar (Size = 4000; Prec = 0; Scale = 0) [changing text] -- @p4: Input TinyInt (Size = -1; Prec = 0; Scale = 0) [0] -- @p5: Input NVarChar (Size = 4000; Prec = 0; Scale = 0) [changing text foo] -- @p6: Input Bit (Size = -1; Prec = 0; Scale = 0) [True] -- Context: SqlProvider(Sql2005) Model: AttributedMetaModel Build: 4.0.30319.1 So somewhere between UpdateModel(t) (where I've validated in the debugger that FolderID updated) and the output of this SQL, the FolderID reverts. The other fields all save. (Well, OK, I haven't validated SaleEffortID yet, because that subsystem isn't really ready yet, but everything else saves.) I've exhausted my own means of research on this: Does anyone know of conditions which would cause a partial entity reset (EG, something to do with long foreign keys?), and/or how to work around this?
