  • GCD function in matlab

    - by SalemFayad
    hi, i am looking for a way to implement the "gcd" function used in matlab in another language but i really cant understand the way it functions. it says in http://www.mathworks.com/access/helpdesk/help/techdoc/ref/gcd.html that: "[G,C,D] = gcd(A,B) returns both the greatest common divisor array G, and the arrays C and D, which satisfy the equation: A(i).*C(i) + B(i).*D(i) = G(i)." but it says nothing about how it calculates C and D. i would be grateful if someone has a clearer idea about this subject! thanks:)

  • How does MySQL's ORDER BY RAND() work?

    - by Eugene
    Hi, I've been doing some research and testing on how to do fast random selection in MySQL. In the process I've faced some unexpected results and now I am not fully sure I know how ORDER BY RAND() really works. I always thought that when you do ORDER BY RAND() on the table, MySQL adds a new column to the table which is filled with random values, then it sorts data by that column and then e.g. you take the above value which got there randomly. I've done lots of googling and testing and finally found that the query Jay offers in his blog is indeed the fastest solution: SELECT * FROM Table T JOIN (SELECT CEIL(MAX(ID)*RAND()) AS ID FROM Table) AS x ON T.ID >= x.ID LIMIT 1; While common ORDER BY RAND() takes 30-40 seconds on my test table, his query does the work in 0.1 seconds. He explains how this functions in the blog so I'll just skip this and finally move to the odd thing. My table is a common table with a PRIMARY KEY id and other non-indexed stuff like username, age, etc. Here's the thing I am struggling to explain SELECT * FROM table ORDER BY RAND() LIMIT 1; /*30-40 seconds*/ SELECT id FROM table ORDER BY RAND() LIMIT 1; /*0.25 seconds*/ SELECT id, username FROM table ORDER BY RAND() LIMIT 1; /*90 seconds*/ I was sort of expecting to see approximately the same time for all three queries since I am always sorting on a single column. But for some reason this didn't happen. Please let me know if you any ideas about this. I have a project where I need to do fast ORDER BY RAND() and personally I would prefer to use SELECT id FROM table ORDER BY RAND() LIMIT 1; SELECT * FROM table WHERE id=ID_FROM_PREVIOUS_QUERY LIMIT 1; which, yes, is slower than Jay's method, however it is smaller and easier to understand. My queries are rather big ones with several JOINs and with WHERE clause and while Jay's method still works, the query grows really big and complex because I need to use all the JOINs and WHERE in the JOINed (called x in his query) sub request. Thanks for your time!

    There is a table: doc_id(integer)-value(integer) Approximate 100k doc_id and 27?? rows. Majority query on this table - searching documents similar to current document: select 10 documents with maximum of (count common to current document value)/(count ov values in document). Nowadays we use PostgreSQL. Table weight (with index) ~1,5 GB. Average query time ~0.5s. Should I transfer all this to NoSQL base, if so, what?

  • How to copy subversion repository as a new directory to existing repository?

    - by Juha Syrjälä
    I have two existing subversion repositories on different hosts (host-a and host-b) and I'd like to copy one directory from repo A to repo B. Basically https://host-a/repo/some/path/moduleA should be copied to https://host-b/repo/some/other/path/moduleA. All the history should be preserved and existing data in host-b should be preserved. The two repositories do not have any conflicting directory hierarchies. The repositories do not share common ancestry.

  • Cross developping targetting both Java Swing and GWT

    - by WizardOfOdds
    Does anyone know of any tool that can facilitate/ease porting of an app to both Java Swing and GWT? I've got a few "screens" that makes complete sense to have both in a desktop app and in a browser and I was wondering if there was some kind of common API that could be targetted that would facilitate creating these two different "views" (see my comment)?

  • Downsides to using FakeWeb compared to writing mocks for testing

    - by ajmurmann
    I never liked writing mocks and a while ago someone here recommended to use FakeWeb. I immediately fell completely in love with FakeWeb. However, I have to wonder if there is a downside to using FakeWeb. It seems like mocks are still much more common, so I wonder what I am missing that's wrong with using FakeWeb instead. Is there a certain kind of error you can't cover with Fakeweb or is it something about the TDD or BDD process?

  • Notification in case of data changes in SQL and Oralce

    - by user171523
    I am in the process of building a system where i need to notify a Window Service a .net based application in case of any change in the DB table (Insert , Update , Delete). I know this can be done with the ADO.NET Events in SQL. Is there any common solution for Oracle and SQL which can provide this kind of notifications. This needs to happen as and when the update happens on real time basis.

  • Localizing MVVM based WPF applications

    - by bitbonk
    What would be a good aproach to localize a MVVM based WPF allication that can change its language at runtime? Of course I could create a string property in the ViewModel for each and every string that is displayed somewhere in the View but that seems rather tedious to me. Is there a common approach/best practice for this?

  • Sharepoint web part stops working because of Resources.en-US.resx file

    - by Eric C
    I've been developing a Sharepoint web part, which had been working fine upon deployment. The web part has been developed with WSP Builder, packaged up and then deployed via stsadm. The web part has been deployed tens, if not a hundred times to the dev box with no problems. Now, the web part throws an error which breaks the page it's on: Object reference not set to an instance of an object. Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code. Exception Details: System.NullReferenceException: Object reference not set to an instance of an object.

I've retracted the web part manually through Solution Management, retracted through stsadm, checked for the existence of the resource file, which is nowhere to be found. I'm pretty much at a loss to why this happened or how to resolve it.

  • UI Code Level Patterns?

    - by DTS
    Is there a book or some other online resource that covers common code-level UI patterns (not widgets/components per se) and idioms. I'm looking for a resource that goes into some depth on MVC, event models, delegates, etc. Something in a similar vein to the POSA series would be excellent. I'm looking for something that is as platform-agnostic as possible, but I'm not sure if that even IS possible.

  • Using Castle DynamicProxy is it possible to change the invocation target on class proxy?

    - by Gareth D
    Hi Using Castle DynamicProxy v2, I'd like to change the target of an invocation for a class proxy. The new target is simply a different instance of the same type as the original target. The target types do not implement a common interface so I cannot use the IProxyTargetAccessor as detailed in Krzysztof's post on the subject - I cannot cast from a class proxy invocator to a IProxyTargetAccessor. Is there a way to do this?

  • How to implement an interface member that returns void in F#

    - by Drew Noakes
    Imagine the following interface in C#: interface IFoo { void Bar(); } How can I implement this in F#? All the examples I've found during 30 minutes of searching online show only examples that have return types which I suppose is more common in a functional style, but something I can't avoid in this instance. Here's what I have so far: type Bar() = interface IFoo with member this.Bar = void Fails with FS0010: Unexpected keyword 'void' in expression.

  • How to define a preprocessor symbol in Xcode

    - by Steph Thirion
    Is it possible to set a symbol for conditional compilation by setting up properties in an Xcode project? My aim is to to create a symbol that is available to all files, without having to use import/include, so that a set of common classes can have a special behavior in some projects. Like the following, but with my own symbols. #if TARGET_IPHONE_SIMULATOR ... #endif
