A sample of code is:

var $b = $('#b');

I am reading the "Clean Code" book and trying refactoring my source code according to the principles "single level of abstraction"/"separation of concerns".
How would you refactor the following code? I am interested in the details like:
- How would you separate the abstraction levels?

It's very easy for setting a format (I know it's no mask):
<datebox format="dd/mm/yyyy"/>
You can found it in the datebox documentation.
Other solution could be from this blog.
Edit :
I don't know why you need a mask. If you set the format to dd/mm/yyyy you can do this :

Here is the story.
We have the BankTerminalSettings class.
It has many properties:
public class BankTerminalSettings {
public bool IsEnabled { get; set; }
public string IPAddress {get; set;}
public ushort TcpPort {get; set; }
public List<string> Zombies {get; set;}
//and ...
I have encountered the following problem that I found very interesting to solve:
Given an array of positive integers {a1, a2, ..., an} you are required
to partition the array into 3 blocks/partitions such that the maximum
of sums of integers in each partition is the minimum it can be.

I've started to write a Generalized Suffix Tree implementation. The overall code is still in an experimental state. Though I think it's mature enough to ask for a little review.
I'ld like to know how I can make it better. Your input would be really appreciated. Especially on the use of the sta...
I'm investigating using prototypes in Javascript to simulate using 'base classes' which can be 'extended'. I've created an example where 'dialogBox' is my 'base' and 'welcomeMessage' is the 'extension'.
// OBJECT CONSTRUCTORS
var dialogBox = function(xPosition, yPosition, width, height){

How should this code be improved:
e.g.
How could it be shorter, clearer, deal with memory better, use a plugin/library, better prepared for web input?
I can break up and clarify the regex or jump calculation, but what is the simplest way?
Why don't I see setTimeout cleared in if blocks more o...
Everything you need to do OOP in one neat little package without having to do all the work by hand. Almost like C++.

var A = Object.extend("A",
{"static" :
{"counter_start" : 5 // all static propertiers and methods should
// be initialized

This challenge took me awhile to figure out, and it's characterized as "easy," so I'm sorta wondering what I missed.

I have created a tetris AI which can play tetris on its own given a set of rules. It places the next piece in every possible way on the board, and calculates which position that gives the fewest "holes" on the playfield.
The playfield is represented by an int[] array, where every bit represents...
Our six magic on-topic questions would benefit from being numbered. Currently:

I recently have been working on a project to simulate segmentation in memory. I wanted to create everything from scratch; not use pre-built data structures.
I create a memory object that allows for "segment" nodes and "hole" nodes.
A segment is: Any location in the memory object that is occupied...

Use case: We have a simple two tables plus a link table setup using some modern RDBMS.
For example:

Visiting_Privilege table (hospital_id, physician_id, ...)
Our goal is to find records that are "missing" (absent) from the link...

I'm taking this programming class and one of our assignments is to make a quiz and return right and wrong answers. So I've coded it all and the only thing that seems to be wrong is my passing of arguments. My result is always zero I'd appreciate any help given.
Thank you in advance,
Chris
