3796 - Backquote, backtic, str and repr in Python - conversion object to string
The backquote or backtic operator in Python is a pseudonym for the repr function. If you have an object that you want to convert into a string (to manipulate it, store it, print it out), Python may call one of two standard method: __str__ (also the str function) converts an object into a human-rea ....

3795 - Like a bathroom company with no plumbers
If I ran a bathroom installation company, I would have chippies, plasterers, tilers, laboureres and plumbers to help me. Customers would be looking for a complete job, and if I was missing any one trade - say I had no plumbers - then the rest of my team would be pretty idle with only the occasional ....

3794 - Should hotel staff sit on the toilet in the customer bedrooms?
Yes, they should - for by doing so, they can see the rooms and the facilities as the customer sees them. It will help them check the good points, and identify places where things need attention that perhaps wouldn't be noticed in a day to day clean. Actually, I'll go further. Staff should stay oc ....

3793 - Excellent Rail News - what it really means
It's been a good week for "Improving Rail Services in Wiltshire". On Tuesday, the first steam train in about 50 years called at Melksham, taking people out for a day trip to Canterbury. On Wednesday, the Department for Transport announced that Wiltshire Council's LSTF (Local Susutainable Transport ....

3792 - Managing daemons from a terminal session
If you want to manage a daemon on a Linux system, how do you do it? • It's likely that you cannot log in directly as the dameon user, as the account will almost certainly not have a valid encoded password string, so every attempt to give a password (including just pressing "enter" when asked) ....

3791 - The Kernel, Shells and Daemons. Greek Gods in computing
The Greek Gods didn't like washing up or ironing. So they employed mortals to to it. Problem was that those mortals didn't last for ever, and sometimes went on strike over one thing and another. So The Gods did a deal with some of the current batch of mortals, and it went like this: "We will make ....

3790 - Solution looking for a problem? Lookahead and Lookbehind
There are some things that it's just plain difficult to find good, practical examples to show delegates on training course. "Solutions looking for problems" I call them sometimes. And one such group are lookahead and lookbehind in regular expression. However, I think I did a bit better yesterday ....

3789 - More than just matching with a regular expression in PHP
There's much more that you can do with regular expressions than just see if a string matches. Here are some examples in PHP, as I was teaching a course in PHP yesterday. 1. You can match, you can match and capture some or all of the matched string, and you can multiple match (and capture) ... see ....

3788 - Getting more than a yes / no answer from a regular expression pattern match
Guy walks up to me in the street and asks "Could you direct me to the Town Centre?". So I answer him "yes, I could", and walk on. Does he thank me? No - he probably thinks "what a useless half answer" or "how rude can you be", even though I completely and correctly answered his question. It's som ....

3787 - Melksham Pride - the Chamber of Commerce, and the future
I'm proud to live and work in Melksham, to have our business visitors come here from all over the world, to use the shops and services on offer here, and to work at a place where we employ lovely people who live in the town. And so are many others. Our "Wilts" room was filled with enthusiasts for ....
