Perhaps you've been reading my blog describing the two Perl courses that I ran in the Middle East over the past couple of weeks. A new part of the world for me - a whole new continent to add to those that I've already visited on business, so I prepared as best I could. I do wish to add a note of ....
The end of a long two weeks ... I'm writing this blog in the reception area at the Dhahran International hotel, ready for posting after an overnight flight back to the UK. My car arrives in about 60 minutes ...

Today is the eye of the storm. And I feel a strange calm. In Saudi Arabia, I run the last day of Perl training that I'm giving here and start for home. In the UK, we complete on the purchase of Well House Manor. ....

Many things were very different in the 1960s to the way they are today. Rosey-tinted spectacles, looking back on what's perceived as a golden age, may persuade many that life simpler and better back then, and there's a saying that "School days are the happiest days of your life". Well - I've news f ....
If you're doing a postal marketing campaign and you get a 5% response rate, you're doing really well - 19 out of 20 circular letters don't get any response, with a fair proportion of them going in the bin unopened. "Cost of Marketing and Sales".

I've just completed a week teaching Perl to a systems administration team, and most of their work is involved in traversing data logs and system reports and extracting pertinent information / seeing when characteristics change - classic for a Practical Extraction and Reporting Language from which "P ....
Here's an extract (reprinted with permission) from an email I received from James - a fellow web site owner, trying to identify visitors to his web site ... he had found and used our IP lookup, and was impressed that we got it right ....
