Is there any reason to do this: private static final Logger LOGGER = LoggerFactory.getLogger(Main.class); instead of this? private static Logger logger = LoggerFactory.getLogger(Main.class); I don't undertstand what the syntactical benefit is of one over the other. Both seem to work fine. ...
I have an __autoload function defined for load classes automatically, if that file has a syntax error, the script stops, simply stops... without error... function __autoload( $var_class ) { require_once( "$var_class.php" ); } echo "Before load..."; new ClassName(); echo "Hello world..."; Output: Before load...

My dreamweaver CS4 will not colour the syntax for HTML5 objects. However, I have downloaded an add-on through Adobe Exchange which allows automatic suggestions for HTML5. But I would love to have the syntax colouring. Any suggestions? ...
I'm working on converting a mathematical formula into a program. This formula is called as optimal pricing policy for perishable products. I've seen this in an article and it is called Karush-Kuhn-Tucker condition. Somehow I lost all my maths skills and unable to understand the formula explained in that. I'm able to understand how to com...
The examples given below could make little sense, but it is because I am focusing on syntax. Let's say I have such C# code: public static class Foo { public const string Bar = "hello world."; } Now, I would like to use Foo.Bar constant in ASP.Net instead of typing each time "hello world.". So I used this syntax: <p><%= Foo.Bar %><...
I've been using TDD/SSR for a while. I'm trying to transition to BDD: context, becauseOf, and Asserts. I'm using Rhino Mocks to isolate, and I'm struggling with syntax now. Here's what I've got so far (note: ContextSpecification class source): public static class DocumentIdAdapterTests { public class DocumentIdAdapterContext : Co...
This is allowed: int a, b, c; a = b = c = 16; string s = null; while ((s = "Hello") != null) ; To my understanding, assignment s = ”Hello”; should only cause “Hello” to be assigned to s, but the operation shouldn’t return any value. If that was true, then ((s = "Hello") != null) would produce an error, since null would be compared to...
If i wanted to do the following: function1 stuff | condition1 = "yay" | condition2 = "hey" | condition3 = "nay" and i wanted to have a statement that always ran, unconditionally, (e.g. "because"), how could i do this? The strings are placeholders. Thanks! Edit: Before i give up on this, i want to try and rephrase it in terms of ...
I've got a large number of PHP files and lines that need to be altered from a standard echo "string goes here"; syntax to: custom_echo("string goes here"); This is the line I'm trying to punch into Perl to accomplish this: perl -pi -e 's/echo \Q(.?*)\E;/custom_echo($1);/g' test.php Unfortunately, I'm making some minor syntax error, an...
This is a thought experiment, I'm interested in your opinion: Does it make sense to you? Do you know whether something similar has already been proposed for the C# programming language? I wouldn't even know where to send such a proposal... The idea is introducing syntax elements to catch an Exception only if it fulfills a certain condit...
I think this is somewhat related to this question, but being not sure and since there's no real answer there, here I go: in Scala there's you can write code such as: aStringArray.map(_.toUpperCase()) which is shorthand for: aStringArray.map(s => s.toUpperCase()) Is there anything like this in F# or a way to implement it (without the...
What would be a good way (along with any pros and cons) of initializing an instance of a PHP class with another object of the same class (ideally in PHP 4.x)? Here in initialize() is essentially what I'd like to be able to do (example is extremely simplified from my use-case, see below): $product = new Product('Widget'); $product2 = ne...

I've never worked on anything like this before, so please I'm want ...
Lots of programming languages already have the compound statements +=, -=, /=, etc. A relatively new style of programming is to "chain" method calls onto each other, e.g. in Linq, JQuery and Django's ORM. I sometimes, more often than I'd like, find the need to do this in Django: # Get all items whose description beginning with A items ...
