• Using JavaScript in WordPress: throw all jQuery plugins in, or is there a way to conditionally load?

  - by ineedtosleep

  I'm relatively new with WordPress theming and JavaScript, though not incompetent with either. I'm looking to have a maximum of 10 jQuery plugins to go on the blog, but I'm wondering if there's a way to have them load only when needed, as I don't want any unnecessary loading for the users. Something similar in something I know a little bit more of would be the conditional comments in IE <!--[IF IE]> @import ie.css <![endif]-->.

• How do I tell ReSharper that an attribute means that a method is used?

  - by Roger Lipscombe

  I'm playing with SpecFlow, and ReSharper thinks that my step definitions are unused (I guess because they're used via reflection): [Binding] public class StepDefinitions { // ... [When(@"I press add")] public void WhenIPressAdd() // R# thinks this is unused { _calculator.PressAdd(); } // ... } How can I tell ReSharper that methods with [Given], [When], [Then] attributes (etc.) are actually used? I don't want to use // ReSharper disable UnusedMember.Global comments.

  - by eibhrum

  Hi, I'm just wondering if there's a web hosting site that offers hosting for PHP and ASP.NET at the same time. It would be great if you give me a site that offers free service.

• When are child views added to Layout/ViewGroup from XML

  - by JohnTube

  My question is : I want to know when does a xLayout (or ViewGroup in general) add a child view from XML ? And by "when" I mean at what point of code, in what "pass" of the "traversal" of the UI toolkit ? Which method of xLayout or ViewGroup should I override ? I have done my homework : I have watched the "Writing Custom Views For Android" presented (by Adam Powell and Romain Guy) in the last Google I/O and I have read Adam Powell comments on this Google+ post.

• What is the best way to use whitespace while programming?

  - by Emmanuel Smith

  I'm fairly new to programming and from learning I have seen different ways of formatting code, comments, etc; and have been recommended on different techniques. I mostly program in C#, C++, and Java so I want to know what is the the best way to layout code so that if other people where to go through it, they would be impressed by how simple and easy to understand it is. I would like to know the same thing for commenting as well.

• iPhone dev - viewDidLoad and viewDidUnload in programmatically created view?

  - by Mk12

  I read somewhere that in a programmatically created view in a UIViewController, not using Interface Builder, -viewDidLoad and -viewDidUnload should not be used. Is this right? Why? Where would I release subviews that I have retaining properties of? Or should I just not use properties for them? EDIT: Read my comments on Rob Napier's answer.

  I need a python script that will do the following: connect to a URL, and that URL will return a number like 1200.

  - by JWD

  What do you think is the best way to implement an interactive grid similar to a Sudoku board for a native iPhone application? I did not see an object to fill this need in the SDK.

• What's the difference between logging and printing to the console

  - by Ankur

  This is kind of a philosophical question. Basically people often ask if I am logging - and since I am not a full time programmer, but someone who programs often but is actually more of a requirements analyst, I don't know all the best practices. I use Java a lot so I often do things like System.out.println() What's the difference in theory between the two? Ultimately aren't I also logging? Esp, if I prefix my comments with something like "ERROR:" or "WARN:" ?

• C++ preprocessor #define-ing a keyword. Is it standards conforming?

  - by Ken Bloom

  Help settle the debate that's going on in the comments at this question about bool and 1: Can a standards-conforming C++ preprocessor allow one to use #define to redefine a language keyword? If so, must a standards-conforming C++ preprocessor allow this? If a C++ program redefines a language keyword, can that program itself be standards conforming?

Reviewer can see all pending changesets in the "review software", review the changeset and decide whether to allow the change into the code trunk. The dev user will receive notification either his changeset was accepted and merged into code trunk, or was rejected.

• How to write a spinlock without using CAS

  - by Martin

  Following on from a discussion which got going in the comments of this question. How would one go about writing a Spinlock without CAS operations? As the other question states: The memory ordering model is such that writes will be atomic (if two concurrent threads write a memory location at the same time, the result will be one or the other). The platform will not support atomic compare-and-set operations.

  - by zyq524

  I'm trying to use regular expression to extract the comments in the heading of a file. For example, the source code may look like: //This is an example file. //Please help me. #include "test.h" int main() //main function { ... } What I want to extract from the code are the first two lines, i.e. //This is an example file. //Please help me. Any idea?
