Hello all! Len Jaffe has a collection of Advent calendars not just about Perl. I don't know if he ever promotes that besides telling me about it every year in the hope that I'll include in the Perl Weekly. It's a pity because it is a great resource. You can find tons of great articles in the Advent calendars. You just need to find the time to read them! Enjoy your week! Gabor Szabo |

by Luca Ferrari I don't know if I'll ever need to write code on a PostgreSQL server, but if I do I know which book I am going to buy. Heck, I might buy it just to learn about a subject I have never used before. Congratulations Luca! |

by David Farrell (DFARRELL) What is a number? Is 2.3 a number? Is 0.3 a number? What about .3 or 2. - are those considered numbers? It all depends who do you ask. Perl comes with Scalar::Util that has a function called 'looks_like_number' that I think embodies this question. Perl won't commit to declare that the given string is indeed a number in your univers. It just say it looks like one. David explains the problems with this function and shows other ways to check if a string is indeed a number. |

by brian d foy (BDFOY) I never thought about this but apparently you cannot write a regex with {N,} where N is larger than 32,766. Try it! This will throw en exception 'x' =~ /b{32767,}/ but don't worry Perl 5.30 will double the limit. I don't think I ever needed such regex with N greater than 17 and even that was just to show an example to my students. If you ever needed more, I'd love to hear your story! If you needed more than 32,766 brian d foy also wants to hear your story! I don't know what brian writes in the article is fun or scary. Or both. |
