3789 - More than just matching with a regular expression in PHP
There's much more that you can do with regular expressions than just see if a string matches. Here are some examples in PHP, as I was teaching a course in PHP yesterday. 1. You can match, you can match and capture some or all of the matched string, and you can multiple match (and capture) ... see ....

3788 - Getting more than a yes / no answer from a regular expression pattern match
Guy walks up to me in the street and asks "Could you direct me to the Town Centre?". So I answer him "yes, I could", and walk on. Does he thank me? No - he probably thinks "what a useless half answer" or "how rude can you be", even though I completely and correctly answered his question. It's som ....

3787 - Melksham Pride - the Chamber of Commerce, and the future
I'm proud to live and work in Melksham, to have our business visitors come here from all over the world, to use the shops and services on offer here, and to work at a place where we employ lovely people who live in the town.

3785 - Programming languages - what are the differences between them?
Comparing the programming languages ... the same program in 10 languages How do I add one to a variable? Some languages have a ++ operator, other languages allow you to use +=, others have an incr command, and in some you have to write a long(er) assignment statement. How do I set up a variable in ....

3784 - Steam train calls at Melksham - Pictures
To my knowledge, this morning was the first time in nearly 50 years that a steam train stopped at Melksham - Steam Dreams running an excursion from Westbury to Canterbury. Midweek seems an unlikely day of the week to attract custom - hardly "prime time" with many people who might wish to go at work ....

3783 - Load path, load and require in Ruby, and a change from 1.8 to 1.9
Ruby loads files through the require command from a list of directories held in the $: special variable, also known as $LOAD_PATH. Up to and including Ruby 1.8, this path list included . (the current directory) but from Ruby 1.9 it does not. Here's a sample program:   require "direct" ....

3782 - Standard methods available on all objects in Ruby
There are a lot of things I can do with any object in Ruby - there's a whole package deal of methods available to me by just defining and creating an object: irb(main):003:0> class Thing irb(main):004:1> end => nil irb(main):005:0> widget = Thing.new => #<Thing:0x98c1e74> irb(main):006:0> widget ....

3781 - Private, Protected, Public in Ruby. What about interfaces and abstract classes in Ruby?
There's no requirement for you to use the words "public", "private" and "protected" in Ruby - methods within classes that you write default to being public anyway. But you may wish to protect certain of your methods from being called directly by the users of your classes. So - what protection do ....

3780 - Ruby of Rails - cleanly displaying model data in the view
The display of data from our model has - thus far - been formatted in the Controller (when that really ought be in the view) and has been liable to fail to display properly if the data contains HTML special characters such as < and &. The solution to this is provided for you by rails - simply ....
