Hi there, Happy Idd to all the weekly newsletter readers who celebrate the festival. We celebrated Idd yesterday in England and I assume it is being celebrated today in my native country, India. For me personally, the highlight of last week was the event organised by the Toronto Perl Mongers. It focussed on the new edition of the book, Data Munging With Perl (2nd edition). Unfortunately I missed the event despite registering for it. However, I'm told the recording will be available soon. If you missed it too, don't worry, you will be able to catch up soon. Speaking of the book, it is one of those must read classics for every Perl programmers. I read it, when it was first released, and I highly recommend you getting a copy to benefit from it. Last week, Gabor mentioned Ramadan seemed to have had positive impact on me as I started writing more frequently these days. He was absolutely right!. But now that Ramadan is over, I'm not sure if I'll continue at the same pace. That said, I truly enjoyed this little burst of writing. It felt like therapy to me. It allowed me to share whatever was on my mind at the time. And when I receive encouraging responses, it gives me even more motivation to keep going. I wrote few pieces last week, all of which are listed below. Please do check them out and share your thoughts. I'd also like to take this opportunity to thank, brian d foy for his incredible book: Perl New Features. I have shared my take on some of the topics discussed in the book, and I highly recommend getting a copy. The latest edition has been updated to cover Perl v5.38. This edition of the newsletter is packed with positive Perl news, so take your time and enjoy. Happy Monday!! Mohammad Sajid Anwar |
