  • Example of xargs' -x option in action

    - by Ole Tange
    GNU xargs has option '-x'. The man page says: -x Exit if the size (see the -s option) is exceeded. But xargs seems to not care if -x is set or not. I have been unable to make an example in which the -x has any effect at all. Please provide two examples in which the only difference is an added -x and that produce different output.

  • grails mockFor closure wierdness

    - by hvgotcodes
    Right, so when I set up my mock using the testing plugin's mockFor method, I expect a method that returns null. If I do myControl.demand.theMethod {return null} in the debugger, the value that I set the 'theMethod' call result to is some closure in the debugger. If I do myControl.demand.theMethod {->return null} the value is null, as expected. I dont understand the difference....

  • jquery document height reported incorrectly by IE (on XP) first time

    - by Zhami
    I'm having a "first time" problem with IE, which reports a different value for $(document).height(); when the page first loads versus subsequent queries. The difference is 17 pixels regardless of the opening size of the window -- on document ready, the height reported is 17 pixels larger than is subsequently reported. I wonder if this is an artifact of some aspect of my page (some margins or paddings somewhere), but so far can't account for 17 pixels.

  • Use of malloc() and free() in C++

    - by Matt H
    Is there any reason to use malloc and free in C++ over their more modern counterparts? Occasionally I see this, and I can't see why some people do it. Are there any advantages/disadvantage, or is there no real difference, except that it's just better to use C++ constructs in C++?

  • Reflection: different ways to retrieve property value

    - by jules
    I'm retrieving an IEnumerable list of properties via following code: BindingFlags bindingFlag = BindingFlags.Instance | BindingFlags.Public; var dataProperties = typeof(myParentObject).GetProperties(bindingFlag); Then I'm iterating through the list and retrieving the value for each property. I've come across two different approaches to doing this, and just wondered what the difference is between them: 1) object propertyValue = property.GetGetMethod().Invoke(myObject, null); 2) object propertValue = property.GetValue(myObject, null)

  • Monitor vs Watch on SourceForge Tracker

    - by Vulcan Eager
    What exactly is the difference Watching and Monitoring a project on the SourceForge Tracker UI? PS: The tool tips are really helpful. Hold your mouse over the "Monitor" button and it says "Monitor this project"... hold it over "Watch" and it says nothing. That's really awesome coming from SF.

  • Qt releasing memory occopied by unneeded images

    - by Gerhman
    I have a QML Flickable with 3 QML image elements that cycle through 8 image files. My problem is for each new image it loads into memory it does not release the the unused image. This is causing memory usage to become double what is necessary at times. I would like to know if there is some function I can use to force it to unload all the unused images? If it makes a difference, this is mainly for Symbian.

  • List comprehension, map, and numpy.vectorize performance

    - by mcstrother
    I have a function foo(i) that takes an integer and takes a significant amount of time to execute. Will there be a significant performance difference between any of the following ways of initializing a: a = [foo(i) for i in xrange(100)] a = map(foo, range(100)) vfoo = numpy.vectorize(foo) a = vfoo(range(100)) (I don't care whether the output is a list or a numpy array.) Is there a better way?

  • Buisness Rule and Process Management?

    - by elgcom
    After some searching in google and wikipedia, I still can not get a clear image about the "difference" between BRMS (Business Rule Management System) and BPM (Business process management)/workflow system. can those two concepts do the same thing from each other? (theoretically) A "rule" can be modeled as a "process" as well. isn't it?

  • Adobe AIR canvas dimensions messed up

    - by Nikhil
    I'm messing about with Canvas in Adobe Air. But their seems to be some issue with the mouse coordinates. The more I click towards the right, the difference between the draw position and actual click increases. My code is Wb.canvas.fillRect(evt.clientX-canvasTag.clientX, evt.clientY-canvasTag.clientY, 50, 50);

  • Update one list from another

    - by lacqui
    I have two multi-select lists in HTML - one of categories, and another of items. What I want is that, when an item selected in the "category" list, everything in the "items" list from that category is also selected. For example, if "Categories" contains "Animal", "Mineral", and "Vegetable", and "Items" contains "Dog", "Cat", "Monkey", "Diamond", "Granite", "Carrot", "Tomato": If "Animal" is selected in one list, "Dog", "Cat", and "Monkey" should be selected; any other selections should remain as they are. I'm using a Symfony PHP backend on the server, if that makes any difference

  • Can I use an abstract class instead of a private __construct() when creating a singleton in PHP?

    - by Pheter
    When creating a Singleton in PHP, I ensure that it cannot be instantiated by doing the following: class Singleton { private function __construct() {} private function __clone() {} public static function getInstance() {} } However, I realised that defining a class as 'abstract' means that it cannot be instantiated. So is there anything wrong with doing the following instead: abstract class Singleton { public static function getInstance() {} } The second scenario allows me to write fewer lines of code which would be nice. (Not that it actually makes much of a difference.)

  • Zend_Search_Lucene vs SOLR

    - by spacemonkey
    Hi, I have recenlty stumbled into Zend Lucene port of Lucene project. I have a little bit experience with SOLR so I would like to know what is the difference between two of them especially from performance and installation side. As much as I know SOLR requires Tomcat serverlet running in web hosting in order to work, what about Zend Lucene library? I am also a bit confused what means "being implemented on the top of Lucene"?

  • Emacs bulk indent for Python

    - by Vernon
    Working with Python in Emacs if I want to add a try/catch to a block of code, I often find that I am having to indent the whole block, line by line. In Emacs, how do you indent the whole block at once. I am not an experienced Emacs user, but just find it is the best tool for working through ssh. I am using Emacs on the command line(Ubuntu), not as a gui, if that makes any difference.
