4375 - Final examples for 2014 - and a look at our 2015 training course options
Following on from yesterday's examples [here] in which I talked you through, with links to code samples, the design and creation of a class, starting off with a description of its behaviour in the form of a test program and adding a test object class too, I'm now adding two short sample programs to ....

4374 - Test driven development, and class design, from first principles (using C++)
I'm teaching OO / class design from first principles today ... in stages. The chosen source language is C++, but the principles are well applied across other OO languages too. Stage 1 - write your test program to make sure it works for your customers want to do. Remember that the "customer is king" ....

4373 - A long and disappointing evening
Somewhere between walking in and being pointed (not shown to) a tiny table along the wall, and walking out through a haze between the smokers, Lisa and I tried the food in a nearby new eatery last night, and decided that it wouldn't be high up our list to recommend to our guests. Is it just because ....

4372 - Template / design pattern for C++ constructor and accessors
Would you believe I'm giving a C++ course on Monday, 29th December? If a customer wants a weekend or holiday time course, yes, we can arrange it! From this afternoon - a first example in C++ - [here]. I've defined the API to a class, the class itself and the first (test) program all in the one ....

4371 - Why are people using the TransWilts?
Although the TransWilts train service just runs (at present) from Swindon to Westbury, with a few extensions to Salisbury, people are making use of the line to connect far and wide. Here's a map showing start and end stations from the surveys (over 3 days) in October 2014: There were over 100 d ....

4370 - Conditionals, loops and methods in Ruby - a primer with simple examples
Continuing with my basic Ruby update - a lot of examples on control structures at [this link]. Conditionals in Ruby include if, unless and case (the equivalent of a switch statement. It's been argued that for a strongly object oriented language a "switch" type structure is not needed, and indeed ....

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 ....

4368 - Shuffling a list - Ruby and Python
Shuffling a list / array is quite a common requirement. The best way to do it is to take a list of all the items to be shuffled, and to choose one at random as the first member of the output list / array. Then move the last item on the incoming array into the gap left, and choose another from the ....

4367 - A year of rail memories!
I used to drive 30,000 miles a year ... but I've reduced that now to around 3,000 - not travelling less, but using the train more. And in 2014, we've had a half-decent service from Melksham that I've been helping to promote. Here are some pictures from the year - some places near and far, some not ....

4366 - Changing what operators do on objects - a comparison across different programming languages
In Object Oriented languages, you used named pieces of code known as methods to perform an operation on a variable - for example you might write   weeklist.extend(weekend) to take a list of (something) for a week and add a list relating to weekend onto the end of it. Sometimes, the method ....
