Creating anonymous objects in php
...w stdClass;
$obj->aProperty = 'value';
You can also take advantage of casting an array to an object for a more convenient syntax:
$obj = (object)array('aProperty' => 'value');
print_r($obj);
However, be advised that casting an array to an object is likely to yield "interesting" results fo...
What are the use cases for selecting CHAR over VARCHAR in SQL?
... varchar (thus consuming less space on my database) and then use a view to CAST everything to it's char equivalent, with the length corresponding to the width of the fixed width for that column. For example:
create table tblStagingTable (
pkID BIGINT (IDENTITY,1,1),
CustomerFirstName varchar(30),

How to determine an object's class?
... are still more methods: Class.isAssignableFrom() and simply attempting to cast the object (which might throw a ClassCastException).
Possible ways summarized
Let's summarize the possible ways to test if an object obj is an instance of type C:
// Method #1
if (obj instanceof C)
;
// Method #2...
Clojure 1.2.1/1.3/1.4 'proxy generated in Grails 2.0.0 runtime fails. 1.2.0 is fine
... an Issue called CLJ-944 on clojure.org. There you can find a fix for ClassCastException: clojure.lang.PersistentArrayMap cannot be cast to java.lang.Class issue
The problem is:
that the compiler injects an incorrect cast to
clojure.lang.PersistentHashMap. In this case it should probably be

How do I use reflection to call a generic method?
...n "normal" usage would have had its type inferred, then it simply comes to casting the object of unknown type to dynamic. Here's an example:
class Alpha { }
class Beta { }
class Service
{
public void Process<T>(T item)
{
Console.WriteLine("item.GetType(): " + item.GetType()

Array.Copy vs Buffer.BlockCopy
...Copy() can perform very poorly here due to the continual "safe" value type casting, compared to the direct casting of Buffer.BlockCopy().
Additional evidence from outside StackOverflow that Array.Copy() is faster than Buffer.BlockCopy() for same-type array copying can be found here.

Order of event handler execution
...store for a particular event. The default backing store for events, multi-cast delegates, are documented as executing in registration order. This will not change in a future framework version. What may change is the backing store used for a particular event.

What are the differences between Generics in C# and Java… and Templates in C++? [closed]
...tOfPerson.
The benefit of this is that it makes it really fast. There's no casting or any other stuff, and because the dll contains the information that this is a List of Person, other code that looks at it later on using reflection can tell that it contains Person objects (so you get intellisense a...
Get current date in milliseconds
...
Casting the NSTimeInterval directly to a long overflowed for me, so instead I had to cast to a long long.
long long milliseconds = (long long)([[NSDate date] timeIntervalSince1970] * 1000.0);
The result is a 13 digit times...
