1850 - Daisy the Cow and a Pint of Ginger Beer
One of the trickiest aspects of learning for newcomers to programming is to know when to split out parts of their code into named blocks. Newcomers can easily see that it's a good idea - as it means that code can be tested in smaller chunks, and that code can be shared (reused) - but it's not alway ....

1849 - String matching in Perl with Regular Expressions
Some languages used adaptive or overridden operator to perform a task depending on the operands - for example in Java, the "+" operator adds numbers, but concatenates strings, and in PHP the == operator compares numbers or strings, depending on the operand types. But in Perl 5, it's often up to the ....

1848 - 30th November - Santa Trip from Melksham
On Sunday, 30th November, Santa Claus will be travelling on the train from Melksham to Swindon and back, and handing out presents to all the children. The train leaves Melksham station at a quarter past five, and will be back just before 7 O'Clock. Tickets (7 pounds for adults and 3 pounds for ....

1847 - Lua - IAQ (Infrequently Answered Questions)
Here are a handful of "one line" answers from the end of the Lua Course I was running at the end of last week • Command line parameters in Lua are available to the program in an indexed table called arg. (Sample Program) • Functions in Lua can look at the number and type of parameters t ....

1846 - Old Piles of the South West
There's a great deal of learned speculation about the construction and reasons behind Silbury Hill (See Avebury) and a lot of digging has taken place over the years to research the issue - so much so that old shafts have collapsed in recent years leading to extensive remedial works. Yet Silbury Hi ....

1845 - Passing a table from Lua into C
In a previous article, I showed you a simple example of how you can call a function that's written in C from Lua, and a second example that extended that - passing simple parameters in to the C function, and returning results. But it's often more complex that that - for example, you may with to pas ....

1844 - Calling functions in C from your Lua script - a first HowTo
This short article shows you how to call a function that's written in C from a program written in Lua, how to write the function that's called, and how to turn it into an appropriate library and load that library. It then goes on (as a second example) to show you how to pass variables from the Lua ....

1843 - How many cups of coffee?
It's exactly two years since we opened our doors at Well House Manor for our first residential training course delegate, and moved from being just a training provider to being a provider of overnight accommodation too. And - goodness me - how much water has flowed under the bridge since then ... o ....

1842 - Lua Course, and the Wiltshire Countryside too
With courses such as Lua Programming, our delegates come from far and wide - it's very much a niche subject, and that's why we provide facilities that are a little different to most training companies - such as our own hotel facilities. The wide spread of our delegates also means that we'll often ....

1841 - Formatting with a leading + / Lua and Perl
In formatted printing, you can often use a leading "+" in the format string to force a positive sign to be added in front of positive numbers - for example "%+4d" means an integer, to base 10, 4 character positions as a minimum, right justified. Here's an example of that, in code, in Lua for john ....
