2244 - What should a web site cost you?
I don't know, but I was asked my opinion on website costs for a government department (the Department for Transport) which have been revealed in a Freedom of Information request here. And I have compared the figures given to the figures for our main web site (www.wellho.net) and for the volunteer " ....

2243 - Changing a variable behaviour in Perl - tieing
What can you do with a scalar variable? When you reduce it to lowest level programming principles, not a lot ... you can create it, destroy it, save a value into it, and read a value back from it. That's about it, when you think of it! In Perl, the low level memory accessors within the language ....

2242 - So what is this thing called Perl that I keep harping on about?
"An overview of the Perl Language" It almost sound like one of those dreaded school essays that I had to write in my several attempts to get an English "O" level (they were the things that came before GCSEs) ... but these days I enjoy writing. No - this little article is one of a decreasing number ....

2241 - Perl references - $$var and \$var notations
In Perl, if I write: $stuff = "Porridge"; then I'm setting up a variable to contain the value "Porridge". If I write: $stuffat = \$stuff; then I'm setting up a variable to contain the ADDRESS OF the variable $stuff. So if $stuff was in memory at (hex)fe80 ... then $stuffat will be assigned that va ....

2240 - How do I query a database (MySQL)?
From my mailbox ... "What are the different ways of queries in databases? Could u pls explain each way in more detail? thanks" The term "query" means something a little bit different in the term "SQL" to it does in regular English usage - the dictionary definition is to ask for information / pose a ....

2239 - Cornerstone Cafe, Melksham
There's a natural concern when a business changes hands. And a deepening concern when virtually all the previous staff disappear. But sometimes, a change is a breath of fresh air and a new bright and different beginning. And so it is with "Kim's Seaside Shack" - or should I say The Cornerstone Cafe ....

2238 - Handling nasty characters - Perl, PHP, Python, Tcl, Lua
Are your writing or maintaining a web based application that uses forms? If so, you have better be aware of some of the nasty characters that are around! The < character, when echoed back from a users's input 'unchallenged', may form the start of a tag. So that in a relatively benign case, a u ....

2237 - Taking a pride in the community
How do you encourage young people to take a pride in their community, rather than engaging is antisocial behaviour? By encouraging their inclusiveness and by providing them with facilities. Lisa and I took a short train trip yesterday, and found ourselves at the station with eye-catching silhouet ....

2236 - Alumni - revisiting and supporting the old University
I have just completed a survey for my old university - I won't name them here, but researchers will be able to find out who they are easily enough, as I made a comment and recommended one of their courses - which actually competes to some extent with what we do - in a comparison chart here recently, ....

2235 - Sending awkward characters by email in Perl
Carrying on from the email work I described in a recent article, I wrote an example today in Perl where I used the mailx program to send an email, piping to it in a system call via an echo. For a one-liner, without special characters in the text, this is easy ... but to get echo to pass through all ....
