Talk review - Idiomatic Perl, David Cross

For 2023 (and 2024 ...) - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))

David Cross's talk on Idiomatic Perl was excellent. I know of Dave from his book Data Munging with Perl so I had some idea of what he was going to be covering.

Now - I've been training in Perl for a number of years, so I didn't expect to learn much technically new, but I did expect to pick up nuances, subtleties, and an indication of a truly independent expert's view as to what is good and what is bad practice. Every programming language needs to have good facilities to cover each facet of its use, but Perl it seems has dozens of facilities for each need. And that's not necessarily a good thing because the code can be written in many styles. The trainer / course author, then, needs to be aware of what is common practice and what is being recommended as future common practice, and what should be avoided (and it's nice to know "why" too).

David - if you ever stumble across this, thank you for the talk. A strong reinforcement of some of the paradigms of Perl that I've been pushing, sometimes a little timidly, in our courses. A reminder of some excellent modules which I have neglected of late, but are now so main-line that they're in the Perl core. And a few golden nuggets which, in the spirit of open source I'll be delighted to use in my own work and spread further. Finally, one or two topics / words presented very differently to I present them - and an inspiration to me to vary, just a little, some of my performances.

Dave Cross:	Graham, Just stumbled across this entry. Glad to hear that you found the talk useful. I assume (from the date) that you were on the Geek Cruise around the Mediterranean. That was a fun week. Anyway, just wanted to say thanks for the write-up. Dave... (comment added 2005-07-12 11:42:15)
