  • maven plugin configuration

    - by Don
    Hi, When writing a Maven plugin, you can configure various parameters within the mojo class, e.g. /** * The path to the properties files. * * @parameter expression="${project.build.directory}" */ private File buildDir; Is there a reference that lists all the available project properties (e.g. ${project.build.directory})? For example, how do I get the value of the resources directory? Thanks, Don

  • Why Emacs/Vim/Textmate? Isn't Xcode good enough?

    - by ivanTheTerrible
    Hi I mostly do C++, Objective-C programming. And I found Xcode plus an auto completion/macro plugin (Completion Dictionary) quite adequate. However, all people seem to praise over their pure text editors. I tried Textmate for a bit; liked its simplicity but dislike its files/framework handling. Am I missing something here? Or, do Vim or Emacs have auto-completion as good as Xcode?

  • Sanitizing MySQL user parameters.

    - by Tom
    What are the dangerous characters that should be replaced in user input when the users' input will be inserted in a MySQL query? I know about quotes, double quotes, \r and \n. Are there others?(I don't have the option of using a smart connector that accepts parameters so I have to build the query myself and this will be implemented in multiple programming languages, including some obscure ones so solutions such as mysql_real_escape_string in PHP are not valid)

  • Load a list of localized strings at once in IOS

    - by Victor Ronin
    I want to show a table with the list of strings which are localized. The straightforward method would be: a) Point data source to my ViewController b) Define an array c) Allocate the array in my ViewController and init (arrayWithObjects) it with the strings from localized resources (NSLocalizedString) d) Use this array in UITableViewDataSource delegated methods Mainly my concern is item b). The construction looks quite heavy and I wonder whether I can somehow specify and load whole list of localized string at once.

  • Options and best practices to release free and paid version of the same app to Android Market

    - by Rich
    I have installed a couple of free apps on my Android phone and then later "upgraded" to the paid full version. My first instincts for doing the same would be to create two apps with the same package name so that installing one overwrites the other, but apps in the Market must be unique by package name. What are some patterns and best practices for sharing code and resources for free and paid versions of the same app and any naming conventions or project structures that work for this scenario as well?

  • Few doubts regarding Bitmaps , Images & `using` blocks

    - by imageWorker
    I caught up in this problem. http://stackoverflow.com/questions/2559826/garbage-collector-not-doing-its-job-memory-consumption-1-5gb-outofmemory-exc I feel that there is something wrong in my understanding. Please clarify these things. Destructor & IDisposable.Dispose are two methods for freeing resources that are not not under the control of .NET. Which means, everything except memory. right? using blocks are just better way of calling IDisposable.Dispose() method of an object. This is the main code I'm referring to. class someclass { static someMethod(Bitmap img) { Bitmap bmp = new Bitmap(img); //statement1 // some code here and return } } here is class I'm using for testing: class someotherClass { public static voide Main() { foreach (string imagePath in imagePathsArray) { using (Bitmap img1 = new Bitmap(imagePath)) { someclass.someMethod(img1); // does some more processing on `img1` } } } } Is there any memory leak with statement1? Question1: If each image size is say 10MB. Then does this bmp object occupy atleast 10MB? What I mean is, will it make completely new copy of entire image? or just refer to it? Question2:should I or should I not put the statement1 in using block? My Argument: We should not. Because using is not for freeing memory but for freeing the resources (file handle in this case). If I use it in using block. It closes file handle here encapsulated by this bmp object. It means we are also closing filehandle for the caller's img1 object. Which is not correct? As of the memory leak. No there is no scope of memory leak here. Because reference bmp is destroyed when this method is returned. Which leaves memory it refered without any pointer. So, its garbage collected. Am I right? Edit: class someclass { static Bitmap someMethod(Bitmap img) { Bitmap bmp = new Bitmap(img); //can I use `using` block on this enclosing `return bmp`; ??? // do some processing on bmp here return bmp; } }

  • How to calculate a measure of a total error in this clustering

    - by Vafello
    I have the following points and clustering of data S1. Can anyone tell me how to calculate the total error associated with this clustering? I know it's not a strictly programming question, but I need it for my algorithm. I think the answer should be 4/3 but I have no idea how to calculate this. Can anyone help me? x1= (2.0,1.0) x2= (2.0,2.0) x3= (1.0,2.0) S1={ x1, x2, x3 }

  • k-combinations of a set of integers in ascending size order

    - by Adamski
    Programming challenge: Given a set of integers [1, 2, 3, 4, 5] I would like to generate all possible k-combinations in ascending size order in Java; e.g. [1], [2], [3], [4], [5], [1, 2], [1, 3] ... [1, 2, 3, 4, 5] It is fairly easy to produce a recursive solution that generates all combinations and then sort them afterwards but I imagine there's a more efficient way that removes the need for the additional sort.

  • How Linux programmers create GUI application without using IDE?

    - by CMW
    Hi, I have read some comments in some forums saying that Linux programmers usually do not use any IDE. They prefer to use Vim and Emacs to do their programming. If I'm not mistaken, Vim and Emacs are just text editors, similar to notepad, but with syntax highlighting. I just want to know how Linux programmers create complicated GUI application without using any IDE. Thanks.
