2804 - Regular Expression Myths
Does this look good to you?   /.*\S+[@]\S+.*/ It shows some regular expression myths that I would like to explode! Myth 1. If you want to match a specific character, you must put it in square brackets. WRONG ... Square Brackets are a grouping - if you're looking to match just a single ....

2803 - Travelling across Europe
Yesterday was a long day of traveling for me - but a pleasure too; "across Europe by train". Perhaps some of the more traveled readers can tell me some of the places I was at?         There are plenty of clues (and in other articles too) for you to work out where I've bee ....

2802 - After the Perl course in Nurnberg
The human body is a very efficient heater ... and it's surprising just how much heat is put out by equipment such as laptop computers. So the last three days in Nuremberg, training a group of 20 in what I'm told is a heatwave for here has been hot. That was 21 people + 21 laptops = 42 heate ....

2801 - Binary data handling with unpack in Perl
During today's Perl course, I was asked to provide an example of the unpack function for extracting multiple values from a piece of data - typically binary data extracted from a file into a scalar variable. Dorothy-2:de$ perl imgsize sd*.gif sd1.gif is GIF, 89a, 450 by 250 sd2.gif is GIF, 89a, 250 ....

2800 - The Merchants And
I remember at school, during French dictation, trying to write the complex word "viagule" which the teacher seemed to be talking about all the time. And loosing so many marks, because it turned out to be the french for a comma ,,,,, .... Yesterday, I was talking about the & character - the Am ....

2799 - Nuremberg - some pictures
Aspects of Nuremberg - for all of those people who are wondering what the place is like. I'm staying in a hotel that's about five minutes walk from the Hauptbahnhof, and rather further from where I'm staying on the outskirts. It's lovely to walk around in the evenings and take picture ....

2798 - Perl - skip the classics and use regular expressions
Perl includes a number of "classic" string handling functions - things like index to find one string in another and substr to get a substring. But you very rarely need to use them because the other string handling functions that are provided are so much more powerful! Here's an example - firstly s ....

2797 - Sur la T.G.V.
It's 8 O'Clock - UK time, Monday morning. An hour later here in France; I'm sitting in a train, waiting for it to leave on the 09:09 service to Frankfurt; a Perl course this week, and I having looked at the travel options (drive, fly), I thought I would try the public transport - surface - option ....

2796 - Sunday - waiting for the ferry.
"This is the best time to drive" says the cabbie who brought me to the ferry port in Portsmouth, from where I'm posting early this Sunday morning. I'm off to train in Germany this week, and I'm traveling overland, by public transport. Something of an experiment; I'll be writing up as I go. Yest ....

2795 - Simon says
I hope I'm never tempted to sell you a five day course when three days will be plenty; that's not just looking for the moral high ground ... it's the practicality of keeping a couple of other days open for other things, and the knowledge that if you get a well timed rather than an elongated course, ....
