What is the difference between SAX and DOM?
...

# -----------------------------

# This file consists of lines of the form:

What do 'statically linked' and 'dynamically linked' mean?
...modules.
The second, linking, is what combines object modules together to form an executable.
The distinction is made for, among other things, allowing third party libraries to be included in your executable without you seeing their source code (such as libraries for database access, network commu...
Why do access tokens expire?
...attacker can abuse a stolen token.
Large scale deployment don't want to perform a database lookup every API call, so instead they issue self-encoded access token which can be verified by decryption. However, this also means there is no way to revoke these tokens so they are issued for a short time a...
What does “Could not find or load main class” mean?
...ided the wrong class name. (Or ... the right class name, but in the wrong form.) Considering the example above, here are a variety of wrong ways to specify the class name:
Example #1 - a simple class name:
java ListUser
When the class is declared in a package such as com.acme.example, then y...
Why do we use __init__ in Python classes?
...dom variable, could contain anything. fido.colour or self.colour is like a form field on the Dog's identity sheet; and __init__ is the clerk filling it out for the first time.
Any clearer?
EDIT: Expanding on the comment below:
You mean a list of objects, don't you?
First of all, fido is actually...
List of Big-O for PHP functions
... And I do understand that practically speaking PHP hashtables give O(1) performance, or at least O(1) on average - that's what hashtables are for. I was just curious as to why you said they are "really O(n)" and not "really O(logn)". Great post by the way!

Can hash tables really be O(1)?
...of the input and n is the number of items in the hash.
The O(1) lookup performance claim makes at least two assumptions:
Your objects can be equality compared in O(1) time.
There will be few hash collisions.
If your objects are variable size and an equality check requires looking at all bits th...
Best practices/guidance for maintaining assembly version numbers
... other is driven by the business.
The following assumes that you use some form of source control and a build server. For context we use TeamCity and Subversion/Git. TeamCity is free for a small (10) number of projects and is a very good build server but there are others, some of which are completel...
What's the difference between equal?, eql?, ===, and ==?
...ridden == method, but there are exceptions. Numeric types, for example, perform type conversion across ==, but not across eql?, so:
1 == 1.0 #=> true
1.eql? 1.0 #=> false
So you're free to override this for your own uses, or you can override == and use alias :eql? :== so the two method...
