2358 - Encapsulating shared code in a Lua module
Have you ever written code like this? seps = {" "," "," [",'] "','" '," ",' "','" "','"'} Yes, I have ... in fact, that's code that I wrote on Tuesday during the Lua course; it's an indexed table of the separators used to split down a web access log record that's in the apache httpd combined forma ....

2357 - Checking if the user has entered a number (Lua)
In Lua, there's a difference between 0 and nil - and that means that you can easily code to ask your user to enter a number, testing the result and allowing him to enter zero as a legitimate value. That may sound like it's no big deal, but you don't want a loop to exit on a premature 0. Here's co ....

2356 - Passing multiple results back from a function - Lua, Python, etc
Have you ever wondered why you can pass in as many parameters as you like to a function, but only return one? It seems rather unfair, doesn't it - especially as you may have lots of results. In fact, in some languages such as Lua you can pass multiple values back:   a,b,c = symie(4,7,9) ....

2355 - See this page in French
Would you like to read this page in French? If so you can do so here ... through Google's "Translate" service ... and this is just an example - I can write other links for other languages, or you can move on from French to another language once you've gone to Google.

2354 - Training, Open Source computer languages
A few days ago, I made a series of postings which summarised our courses in major western European languages - with a view to having the information about our courses available / findable to people who's mother tongue is perhaps Swedish or Italian, but who have good English and could benefit from ou ....

2353 - All change - Wiltshire Parliamentary
At the weekend, I read that James Gray, the MP for Chippenham, had remarried. And, yesterday, that Michael Ancram, MP for Devizes (which includes Melksham) has taken the decision to stand down at the next general election. Goodness - how times change; four years ago, when I first got more actively ....

2352 - Printed Directories - the start of the updating season
I don't know how many business directories there are - but I do know it's the season for all the directory providers to start phoning around and sell spaces in their publications. I have spoken with two in the last two days! So it's very fortunate that Lisa and I spent Saturday going through the ....

2351 - Ternary operators alternatives - Perl and Lua lazy operators
"If the gender is male, the answer is him, but if the gender is female, the answer is her". A common situation in programming - [is/are], [him/her], [yes/no], [child/children], [ice/water/steam], [public/private] - and C and Perl and PHP provide the "ternary" operator ? and : to provide a shorthan ....

2350 - Ten years in Melksham - looking forward to ten more.
It's ten years to the day since we bought "404" - our home in Melksham Spa. An eerie takeover, with contracts being exchanged in the morning and we arrived to accept vacant possession just as the sky darked for the eclipse ... the great, tall Spa building in the half light, and the crows from the r ....

2349 - Businesses effected by road works in Melksham
"Businesses Open as Usual" say the signs on the High Street in Melksham ... currently (and for 14 weeks) a one-way system while various pavement works are being done. Who wrote that sign? ... for he certainly doesn't know Melksham! I took my customers into one of the businesses in the effected are ....
