2293 - Regular Expressions in Ruby
Ruby has a wide variety of string handling methods, and a very strong regular expression engine. In one of the example I wrote today ([link] Regular Expression Example in Ruby) I've included a primer on the elements of a Ruby Regular expression as well as sample source code - showing you how you ca ....

2292 - Object Orientation in Ruby - intermediate examples
It's when you teach object orientation - the fully Monty, including inheritance, static and dynamic methods and variables, and so on - to a complete novice to programming and that person finds it's one of the easiest parts of the course that you realise: a) Just how many bad ole habits us ancient s ....

2291 - Collection objects (array and hash) in Ruby
Ruby has two collection objects - Arrays (where you access elements based on their numeric position) and hashes (where you can access elements based on a key, rarely numeric). That's similar in all but name to many other languages, although the names may be different (arrays or lists; hashes or dic ....

2290 - Opening and reading files - the ruby fundamentals
Once you've noted that File.new doesn't create a new file, but rather (default) opens an existing one for read ... you'll find Ruby's file handling interface easy to use. The new methof returns a file handle object - a sort of buffer that sits between the file and your program - and each time you r ....

2289 - pre-Inaugural briefing - Melksham Community Area Partnership
14th July, Semington Village Hall - the sort of inaugural meeting of the Melksham Community Area Partnership (see about CAPs and about Wiltshire's new structures). I wondered why Semington Village Hall for a "Melksham" meeting - Semington Village has been made an awkward place to drive to due to ro ....

2288 - Wiltshire Community Area Partnerships
A few days ago, I wrote about all the new structures at Wiltshire Council; I was having trouble working out what they all did, and I don't think I am the only one having trouble understanding it. (See that article). I got stuck at "Community Partnerships" or "Community Area Partnerships" which seeme ....

2287 - Learning to program in Ruby - examples of the programming basics
We so often overlook the basics of programming, and yet they are so fundamental to good code - understanding things like how widely variables can be seen (also known as variable scope), what happens when you divide two numbers (do you get a decimal result or is the remainder thrown away), and how do ....

2286 - New to programming? It is natural (but needless) for you to be nervous
Yesterday, I ran the introductory day at the start of our Learning to Program in Ruby course. Delegates come to us to learn a programming language with two different backgrounds - "I have programmed before in xxxxx and now I need to learn QWERTY" (the converters) and "what is this programming thin ....

2285 - Great new diagrams for our notes ... Python releases
When training, I project onto a white wall ... and I draw onto the projected image, and add extra notes and diagrams around the side too - after all, the whole wall is a whiteboard. Some of the diagrams and slides that I'll come up with are new / unique for an individual course, and I end up photog ....

2284 - Strings as collections in Python
In Python, I can treat a string as a collection of characters and iterate through it without the need to do any sort of conversion on it, or muck about with "substr" ... breakfast = "Croissants and toast"   for letter in breakfast:    print "Give me a ",letter   print "and ....
