140 - Comparison Chart for Perl programmers - list functions
grep v map v sort Most languages support lists and / or arrays - and that includes Perl. In Perl, though, you can use functions such as grep, map, sort and reverse to operate on lists as a whole rather than having to loop through members of the list cell by cell. functiondesciption of actioneleme ....

139 - Just provide a room and the students
I'm sitting, writing, in our training room and there are 9 laptops on the desks ready for the final day of Perl for Larger Projects. That's one laptop per trainee, some spares, a laptop off which we project course notes, and the system I'm writing from. Operating systems? A mixture of Unix, Linux ....

138 - Perl - redo and last without a loop
Perl has next, last and redo commands which (by default) cause you to move on to the next iteration / exit from / repeat the same iteration of a loop. Did you know that you can also label a block and then use them in a similar way in that block? $c = 1; $d = 4; thyme: { $c++; $e = 5; redo thyme i ....

137 - Certification schemes
Should we offer certified training courses to agendas laid down by the likes of Sun, Adobe and Zend, or should we offer courses to our own agendas? There are arguments both ways, and we reconsider from time to time. I thought you might be interested in a (slightly long) item I wrote in response to ....

136 - Please tell us
So often, I have said "if you like what we provide, tell your friends, if you don't, please tell us". That's not my original line, but it's good practice. And it's heartfelt too ... Recently, we released about 500 pages (out of 3000) of our training notes under an Open Training Notes license on ....

135 - Too many Perls
Why do people invent new programming languages? In some cases it's for commercial reasons - they want a share of the cake and really they would be far more efficiently employed elsewhere; I guess that languages such as J++ and C# fell/fall into this category, but then that's a personal view that n ....

134 - Geekmas - a brief review
What a fun weekend! Thank you for coming everyone! Now it might not be everyone's idea of fun, but our training room was stuffed full on Saturday afternoon and Sunday morning with "geeks" - I hope you don't mind me calling you that - as we explored views and exchanged ideas on open source language ....

133 - Tcl embeds
Tcl is perhaps the most "niche" language in which we provide training courses - and also perhaps the oldest. It's used as an embedded language - being written into larger pieces of software to provide a tailoring capability for the users. This means that typical users are required to write just ....

132 - Portrait of the author
You could walk past this stockily-built 36 year old of Scandinavian decent, polite, short haired, short trousered on this cruise ship and not notice him amongst the other 2000 guests. And, yes, he can and does circulate freely without challenge. Those few of us who know who he is respect his privac ....

131 - Thanksgiving dinner
Yesterday was American's Thanksgiving Day, and having a wife who was born American in North Carolina and lived for many years before I met her in Florida, it's one of the special days / times on a par with Christmas and Easter that we celebrate a little. We sat our our dining table with friends and ....
