  • Should I be using callbacks or should I override attributes?

    - by ryeguy
    What is the more "rails-like"? If I want to modify a model's property when it's set, should I do this: def url=(url) #remove session id self[:url] = url.split('?s=')[0] end or this? before_save do |record| #remove session id record.url = record.url.split('?s=')[0] end Is there any benefit for doing it one way or the other? If so, why? If not, which one is generally more common?

  • Freely-available, well-debugged regular expressions

    - by fsb
    I was reading ICU documentation and came across this fine advice: For common tasks like this there are libraries of freely available regular expressions that have been well debugged. It's worth making a quick search before writing a new expression. To which libraries of well-debugged regular expressions do you commonly refer? I'm not much taken with http://regexlib.com where the expressions don't seem all that well debugged. It appears to have no QA process besides user comments and ratings.

  • What is the most efficient procedure for implementing a sortable ajax list on the backend?

    - by HenryL
    The most common method is to assign a sequential order field for each item in the list and do an update that maintains the sequence with every ajax sort operation. Unfortunately, this requires an update to each item of the list every time someone sorts. This is fine for small lists, but what's the best way to implement sorting for larger lists that are constantly updated? I am looking for something that minimizes DB IO.

  • Parse multiple filters in SQL

    - by Jeff Meatball Yang
    I have a problem parsing a stored procedure parameter in the form: declare @S varchar(100) set @S = '4=2,24=1534' Here's the query: select cast(idx as varchar(100)) 'idx' , value , SUBSTRING(value, 1, charindex(value, '=')+1) 'first' , SUBSTRING(value, charindex(value, '=')+1, LEN(value)-charindex(value, '=')-1) 'second' from Common.SplitToTable(@S, ',') -- returns (idx int, value varchar(max)) where len(value) > 0 But here is the result I get: idx value first second 0 4=2 4 4= 1 24=1534 2 24=153 Here's what I expected: idx value first second 0 4=2 4 2 1 24=1534 2 1534 Help?

  • How to add multiple handlers to an attached event in XAML ?

    - by Gishu
    I want to add 2 handlers to a particular event like shown above. However this won't compile - 'attribute can be set more than once'. I have multiple methods because they do different things (are named appropriately). e.g. the first handler has nothing in common with the second. My other option was to kludge a SetFlagForCursorTrackingAndCheckForViewLink method - which is "Yech!". Any ideas ?

  • What is the difference between using IDisposable vs a destructor in C#?

    - by j0rd4n
    When would I implement IDispose on a class as opposed to a destructor? I read this article, but I'm still missing the point. My assumption is that if I implement IDispose on an object, I can explicitly 'destruct' it as opposed to waiting for the garbage collector to do it. Is this correct? Does that mean I should always explicitly call Dispose on an object? What are some common examples of this?

  • when does static member gets memory.

    - by vaibhav
    I have a class which have a static member. As I understand all static members are common for all instance of the class. So it means static members would get memory only once. Where is this memory is allocated (Stack or Heap) and when this memory get allocated.

  • jQuery oembed plugin z-index problem

    - by Ben
    I'm using the jQuery oembed plugin to display videos from a Vimeo feed. The only problem is they display over the top of my navigation menu. I have tried setting the z-index of the menu but this makes no difference. A common suggestion seems to be to set the wmode parameter to transparent or opaque. However, passing this as a parameter to the oembed function makes no difference. Thanks

  • How to find where a library is used across multiple pom files

    - by Pablojim
    We have multiple maven projects depending on on our own common libraries. When we upgrade a library it would be useful to quickly find out which projects have a dependency on the library (and might need to use the new version) Obviously I can manually look in all the pom files or write a script to do it but this is less than ideal. Are there any tools that provide this functionality. e.g. a hudson plugin, Nexus, artifactory etc?

  • Big, Thick Reference Books (PHP / MySQL / Unix) [closed]

    - by Josh K
    I'm looking for in-depth reference books / guides in PHP, MySQL, and Unix. I'm aware there other other questions pertaining to good books for short references of function names, or detailed beginner guides to these systems. I'm looking for something different. I want a book that I can either use as a quick but in-depth (decent write up, not a pocket reference guide) reference to common functions (JOINS, string manipulation, Regular Expressions, etc) while also providing a detailed inner workings explanation on the system itself.

  • javascript: how to delay submitting data when several checkboxes clicked in short time interval?

    - by ~knb
    I have an array of checkboxes in a complex dynamic-html form. Whenever a user clicks one checkbox, a fairly expensive query is generated and submitted to a remote server. I want to delay this submit action depending on the users next action. If the user clicks several checkboxes quickly, all of the first clicks should be discarded, only the last one is processed and eventually submitted after 1 second or so. maybe this is a common problem but I have never worked with timeouts before.

  • What tricks do you use to get yourself "in the zone"?

    - by Tim Jarvis
    Once I am "in the zone" I am extremely productive and code just flows out of me, often I can get 2 or 3 days coding done in 1 day. But I find that often its hard to get to that place, I find myself procrastinating, getting distracted by other things (SO for example). Is this experience common? How do you force yourself into that state of mind? Is it simply something you can't force?

  • How do I specify a project dependency with Hudson?

    - by Brett Ryan
    We have common library projects shared amongst many projects that are required to be checked out into a "Libraries" folder which a developer needs to checkout prior to opening the main project in visual studio. How I tell hudson that there is this dependency? I figured one thing I could do is setup a custom workspace and specify the location for all projects, but how do I wire up the dependency between them all? Is simply specifying "Build after other projects are built" enough?

  • drawing circle without floating point calculation

    - by zaharpopov
    This is common interview question (according to some interview sites) but I can find no normal answers in Internet - some are wrong and some point to complex theory I expect not looked for in interview (like Bressenham algorithm). The question is simple: The circle equation is: x^2 + y^2 = R^2. Given R, draw 0,0-centered circle as best as possible without using any floating point (no trigo, square roots, and so on, only integers)

  • How to store enum values in a NSMutableArray

    - by Oysio
    My problem is since an enum in objective-c essentially is an int value, I am not able to store it in a NSMutableArray. Apparently NSMutableArray won't take any c-date types like an int. Is there any common way to achieve this ? typedef enum { green, blue, red } MyColors; NSMutableArray *list = [[NSMutableArray alloc] initWithObjects: green, blue, red, nil]; //Get enum value back out MyColors greenColor = [list objectAtIndex:0];
