  • MonoRail - How to grab records where a column isn't null

    - by Justin
    Hey, In MonoRail/Active Record if I want to grab all records that have a certain column equal to null, I can do: public static Category[] AllParentCategories() { return (FindAllByProperty("Parent.Id", null)); } However, what if I want to grab all records where that column doesn't equal null? I can't figure out how to do that using this FindAllByProperty method, is there another method that is more flexible or a way to grab records using a linq-like querying language? Thanks, Justin

  • How can I add multiple pre-commit SVN Hooks

    - by Alister Bulman
    I've got several pre-commit hooks that I would like to run before each commit. Right now, they are all just shell-scripts, so I know i could just concatenate them to get them all to run. In the future though, additional scripts may be written in Perl, PHP, or some other language as well. How can I run several different scripts as part of a single pre-commit hook?

  • How can I demonstrate the benefits of abstractions to an old-time C programmer?

    - by Zaban Khuli
    Hi, there's this senior developer in my company that programs in C. I happen to be from functional background (ML, to be specific). This senior C programmer refuses to use abstractions because "abstraction is for lame programmers and _real_ programmers do not need it." I can not seem to convince him otherwise Is it a problem with only this programmer or do all C (and other lower level language) programmers have this opinion that abstraction is for lame programmers?

  • Expert R users, what's in your .Rprofile?...

    - by gappy
    This question is maybe a little too cute, but I have always found startup profile files of other people both useful and instructive about the language. Moreover, while I have some customization for bash and vim, I have nothing for R. For example, one thing I always wanted is different colors for input and output text in a window terminal, and maybe even syntax highlighting.

  • Scriptaculous Sortable.create - Can't hook the dragged element

    - by Tom
    When using Sortable.create I can't seem to get the element that is being dragged. Does Sciptaculous not fully implement all Draggable and Droppable features when you use sortable? Given: Sortable.create("sortArea", {scroll:window, onChange:orderLi}); function orderLi(){ console.log(this.draggables.each(function(e){if(e.dragging==true){return e};})); } My console always shows all the array of draggables. How do I only grab the one that is being dragged?

  • Why is the ( ) mandatory in the SQL statement select * from gifts INNER JOIN sentgifts using (giftID

    - by Jian Lin
    Why is the ( ) mandatory in the SQL statement select * from gifts INNER JOIN sentgifts using (giftID); ? The ( ) usually is for specifying grouping of something. But in this case, are we supposed to be able to use 2 or more field names... in the example above, it can be all clear that it is 1 field, is it just that the parser is not made to bypass the ( ) when it is all clear? (such as in the language Ruby).

  • Cant get description rss tag data with javascript

    - by AdamB
    I'm currently making a widget to take and display items from a feed. I have this working for the most part, but for some reason the data within the tag within the item comes back as empty, but I get the data in the and tags no problem. feed is and xmlhttp.responseXML object. var items = feed.getElementsByTagName("item"); for (var i=0; i<10; i++){ container = document.getElementById('list'); new_element = document.createElement('li'); title = items[i].getElementsByTagName("title")[0].firstChild.nodeValue; link = items[i].getElementsByTagName("link")[0].firstChild.nodeValue; alert(items[i].getElementsByTagName("description")[0].firstChild.nodeValue); new_element.innerHTML = "<a href=\""+link+"\">"+title+"</a> "; container.insertBefore(new_element, container.firstChild); } I have no idea why it wouldn't be working for the tag and would be for the other tags. Here is an example of the rss feed its trying to parse: <rss version="2.0" xmlns:dc="http://purl.org/dc/elements/1.1/"> <channel> <title>A title</title> <link>http://linksomehwere</link> <description>The title of the feed</description> <language>en-us</language> <item> <pubDate>Fri, 10 Jul 2009 11:34:49 -0500</pubDate> <title>Awesome Title</title> <link>http://link/to/thing</link> <guid>http://link/to/thing</guid> <description> <![CDATA[ <p>some html crap</p> blah blah balh ]]> </description> </item> </channel> </rss>

  • Is there a good date/time API available for Scala?

    - by Erik Engbrecht
    I'm looking for something akin to JodaTime or JSR 310 for Scala that leverages nice Scala features such as operator overloading and doesn't rely on implicit conversions (I have an irrational fear of implicit conversions). I'm aware of http://github.com/jorgeortiz85/scala-time, but it just pimps JodaTime with implicits.

  • Need algorithm to add Node in binary tree

    - by m.qayyum
    •if your new element is less or equal than the current node, you go to the left subtree, otherwise to the right subtree and continue traversing •if you arrived at a node, where you can not go any deeper, because there is no subtree, this is the place to insert your new element (5)Root (3)-------^--------(7) (2)---^----(5) ^-----(8) (5)--^ i want to add this last node with data 5...but i can't figure it out...I need a algorithm to do that or in java language

  • Any C/C++ to non-native bytecode compiler/interpreters?

    - by Matt
    As the title indicates, are there any C/C++ bytecode compilers/interpreters? I'm writing an application in an interpreted language that depends on certain libraries that are fully cross-compilable (there are no special flags to indicate code changes during compilation for a certain platform) but are written in C and C++. Rather than shipping n-platform-specific-libs with each platform, it would be nice to ship one set of libs which are interpreted by one platform specific interpreter. Possible and/or available?

  • operator "new" returning a non-local heap pointer for only one class ?

    - by KaluSingh Gabbar
    Language : C++ Platform : Windows Server 2003 I have an exe calling a DLL, in which when I allocate (new) the memory for class A (which is in DLL) it returns me a non-local heap pointer. I try to new other classes which are in DLL and "new" returns a valid heap pointer for them, its only Class A which is not being allocated properly. I am on windows and validating the heap by this function call : _CrtIsValidHeapPointer ( (const void *) pPtr ) I am seriously confused why this only happens with new-ing Class A and no other class ? (All Native Code)
