1866 - What a difference a day made
Friday ... room set up at Well House Manor for a Business Networking International breakfast. Saturday ... room set up at Well House Manor for a MGphoto training day. And in between these two events, I presented the final day of my Perl course! At Well House Manor, we provide Open Source Traini ....

1865 - Debugging and Data::Dumper in Perl
I'll admit it - I'm not a great fan of debuggers, preferring to write well structured code, and check it out with a few test / intermediate print statements. You'll often find I code:     $trace and print (something); in Perl, and this allows me to add a line     ....

1864 - Object Oriented Perl - First Steps
There are some occasions when a new example that I write / a topic that comes up on a course results in an article that's so long that it doesn't fit into the Blog / short article format, but requires a more substantial mechanism. And so it is for my First steps in Object Oriented Perl examples, wr ....

1863 - About dieing and exiting in Perl
If you want to end a program in Perl, you can get out quickly enough with an exit function call. But that's probably just a part of what you'll be wanting to do - you'll be wanting to generate an error message on the error channel (STDERR) too, and perhaps to tell your user rather more about why the ....

1862 - Remember your units
I remember one of my maths teachers at school - a certain Mr Shaftesbury - who despaired of me. I think he was the one who told my parents I would never be able to do even simple arithmetic. I was reminded of him a couple of hours ago when our order for 4 carrots turned up as 4 kilograms of carrot ....

1861 - Reactive (dynamic) formatting in Perl
If you want to format your data neatly in columns, you can use sprintf or printf to do so if you're using a fixed width font. A format of "%20s", for example, calls for a string that's 20 characters long and will be trailing space padded ... except ...that figure "20" is a minimum width, and if yo ....

1860 - Seven new intermediate Perl examples
From the "learning to program in Perl" course I'm running this week, I am pleased to present seven new examples ... written during the course, in front of the delegates, to show them NOT ONLY how the code works, BUT ALSO how a programmer will develop such code. Lists and Context * If you use an @ ....

1859 - Wiltshire at dawn - the tourist trail
With the clocks going back at the weekend, it's no longer possible for us to show delegates on our courses some of the lovely Wiltshire countryside after we're done with training for the day. Which is a great shame when there are lovely places like Lacock Abbey around. So this morning ... we wen ....

1858 - Camera with night vision, youth with no vision
I'm rather pleased with my current digital camera - it's able to take good evening and night shots of the sort I would scarcely have thought possible a couple of years ago. This image is at Westbury Station last Sunday evening, when the Portsmouth to Cardiff trunk service had been replaced by a bus ....

1857 - November and December Public Course Schedule
It's only a couple of days since we turned the clocks back, but already my weekday time is fully spoken for up to Christmas - with bookings on all of these public courses so they're guaranteed runners (remember - we never cancel a course once you've booked it!) November 2008 Python Programming [Lin ....
