Ruby is a modern, scripting Object Oriented language

extras, and used as the basis for Ruby on Rails ("RoR"),

|4498||Ruby - where one statement ends and the next begins|
In Ruby, you can end your statements with a ;, but it's more usual to simply let them end at the end of a line. Ruby can usually identify where a statement ends and if it clearly doesn't end on one line, it carries on to the next.
Just occasionally, this can be little bit of a trap. Look at this ...
|4369||Ruby - the second rung of learning the language|
When you're learning a programming language - or to program - your text / tutor will almost inevitably start with "Hello World" - a program to display a string of text. That's chosen as the first example as it shows you how to enter and store you program, it shows you any steps necessary to convert ...

We passed through New York on our way up from Washington DC to Albany, NY State; a 3-hour layover gave us a chance for a quick meal (there's no better city for a choice of foods), and a chance to look through a book store (there's no better country to look through the shelves for the next trend).

What is Ruby on Rails?
Ruby on Rails is a clever way of programming your web server in Ruby - it allows you to have data in databases on your website and provide very easy access tothat data through a browser, allowing your customers to see the data and you staff to see it, alter it, and add more data ...
|1375||Python v Ruby|
Ruby v Python ... I've been asked for a comparison!
• Both are object oriented scripting languages - or rather claim to be scripting languages, but are really compile-and-run via their own virtual machines, in just the same way as Perl and Java are.
• Both are modern, Open Source languages ...
|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 thing ...
|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 ...
|1887||Ruby Programming Course - Saturday and Sunday|
We're so busy during the week at the moment that I'm running an extra Ruby Course this weekend. The main use of Ruby is within "Ruby on Rails", but our course concentrates on the language itself and so it's suitable for people who are using RSpec, cucumber and Watir as well as Rails.
Here are some ...

I'm not musical ... but this song keeps jigging around in my head.
"I'm back in the saddle again.
Out where a friend is a friend,
where the longhorn cattle feed
on the lowly gypsum weed.
Back in the saddle again."
First course of the New Year ... done, run and I love it!

I spotted a 1 day Ruby conversion course - presented by one of the "movers and shakers" behind Ruby and Rails - over Easter. And in Europe rather than the USA or Japan too. Fabulous - I'm always keen to learn from the masters; time and money spent listening to the originators of Perl, PHP, MySQL and ...
