872 - Email metrics
How many emails do YOU get each day? How many of them are unsolicited bulk emails that you throw away without evening opening them, or have your server reject? A long time ago, I wrote a PHP script that gives me a quick traffic graph looking back a number of weeks so that I can spot a changing p ....

871 - Java oversold?
Oops ... I missed my blog entry yesterday - indeed, I had been up so early in the morning after a short night that I fell asleep around 8 p.m. and slept through - didn't even hear Lisa come in from her "Villager" meeting. But, running crisply again this morning I've already spoken with plasterer, pl ....

870 - Autumn comes to Wiltshire.
A misty Sunday morning in Wiltshire - Autumn is here and it'll soon be time to turn on the heating. For us, it will be another long day of preparations for the opening in just 3 weeks time of Well House Manor. Our bedroom, on the second floor of the old Spa House, looks out through a wrought iron b ....

869 - UNABLE TO ATTEND
"Unable to Attend" - so says the notification attached to a refund cheque that I've received for a course that I had booked in May to attend in July. It's taken two months to get the refund. I felt the wording "unable to attend", whilst technically correct - was extremely cheeky. Why was I una ....

868 - Smoking, or no
"No Smoking". That's the story at our training centre, and at Well House Manor too. But there's a further story that says "but these delegates and hotel guests are our customers and we provide them with a service that doesn't restrict them". A paradox; one man's freedom to smoke in the lounge is ....

867 - Being sure to be positive in Perl
Perl's printf and sprintf routines (and functions with similar names in C and PHP, and the Python % operator) all provide us with a reasonably flexible way of formatting floating point numbers, but they can't meet every eventuallity. At times, you'll need to use sprintf to do most of the work then a ....

866 - A lazy programmer is a good programmer
I'm lazy. By which I mean, if a job can be done once in such a way that I don't have to keep doing it time and time again, then that's how I will try and do it, even if there's a bit more effort and cost at first. That's why (for example) we've laid an underground water pipe out to where we're pla ....

865 - Catching the slope
I find it very hard to capture slopes and hilly tracks in photographs. What I feel is very hilly and quite spectacular out there on the ground turns out to be flat and boring when loaded in from camera and leaves me, let alone my audience, saying "so what". There's a similar issue with some of th ....

864 - Add to shopping cart - NO VACANCIES sign
I've been writing a standard piece of text this morning that says "Sorry - we're full on xxxxx night(s) and can't offer you a bedroom" ... and Well House Manor doesn't even open until early next month. And I've also taken a decision to block all remaining rooms on an "event" evening, as having just ....

863 - Double and Triple equals operator in PHP
Have you been given a piece of code to maintain that has single, double and treble equal operators in it? What's the difference? A single = sign is an assignment - take what's on the right as an expression and save it in the variable named on the left. A double = sign is a comparison and tests whe ....
