4576 - If it's Tuesday it must be Belgium?
It's been one of those "If it's Saturday it must be Bristol" type weekends and week starts ... except here I am just after midnight, early Wednesday morning in Swavesey, ready for a Python course starting tomorrow. Past days have been both Euphoric and tiring - with Railfuture awards on Saturday ( ....

4575 - Learning not just what a program does, but how to design it in the first place.
A Programming course is not only about how a language works, but also about teaching the delegates to to plan their applications and programming using that language to make best use of existing resources, to develop code that works well and can be re-used and updated as the requirements drift in the ....

4574 - repeat until in Lua - a one or more rather than a zero or more loop
The "repeat until" structure in Lua provides a loop with condition checking at the end - in other words, it's a "one or more times" loop, unlike while which is a "zero or more times" loop. Syntax - straightforward; example:   repeat     io.write("How many people? ") & ....

4573 - Classic style OO code - in Lua
Lua tables can hold not only data values, but also functions - those functions defining behaviours. See [here]. However, if you have a lot of tables (data items) all of which require the same code attached, that's not efficient and so you can set up a metatable - a subsidiary table of extra inform ....

4572 - Tables with values and code in Lua - looks like an object?
In Lua, we can use variables to hold both data and code, and we can use tables to hold groups of values (numbers and strings) and code assiciated with those variables too. A new example - [here] on our web site - shows how I can define such a table:   south = {cars=3,seats=78,time="06:38 ....

4571 - Lua - using modules to add your own utilities
Lua is a small language ... but that doesn't mean it lacks capabiities - it just means that you need to write some code yourself to implement simple utilities that you would cherry pick from huge libraries in other languages. For example from this week's course, I've written functions to split a li ....

4570 - A warm welcome awaits you at Well House Manor, Melksham
We've a number of events happening at Well House Manor this week - an external training course run for a local company in one room, a course of our own in a second room, a social / informal company meeting for another organsation in a third room ... and guest coming to stay overnight with us, to rea ....

4569 - Lua - changes to how integers and floats are handled - 5.2 to 5.3
Lua has historically worked internally with floats (actually doubles) even when given whole numbers. The logic was a good one - to keep the language small with a limited number of data types, and for the latest generation of hardware the speed of operations on floating points and doubles really wasn ....

4568 - Moderation - and the tendency to over-moderate
I find myself out of step with the administrators and moderators of many of the facebook groups and forums that I'm a member of. Whilst there is a need to provide some sort of framework on the activity and direction of the board, I can't help feeling that many board's teams are far too controllingl ....

4567 - Japanese and Malaysian food in Melksham
I'm delighted that "The Unicorn" in Melksham has re-opened as a Japanese and Malaysian restaurant and Takeaway, lunchtime and evenings, 7 days a week. Lisa and I tried a Malaysian takeaway last week, and we ate in for lunch yesterday with Dad - Japanese starter illustrated. Very tasty - we'll ....
