Hi there! At the end of this issue you'll find the upcoming Perl-related events 3 of them YAPCs. YAPC::NA is the first one with 286 committed users. You still have 2 weeks to register. YAPC::Asia is almost 2 month away. It is the largest YAPC by far expecting 2,000 participants this year. For them while its rooted in Perl, YAPC::Asia Tokyo 2015 is an event that any engineer will be able to enjoy. YAPC::Europe is the furthest away in time with a new, call for talk proposals extended to solutions that are not necessarily in Perl. This is your opportunity to turn YAPC::EU 2015 into an event interesting to people who have not been exposed to Perl yet. Enjoy Gabor Szabo |

by brian d foy (BDFOY) A whole new meaning of defensive programming? The example is how to localize system-wide changes. If you put 'local $_ = undef;' in a block that will ensure '$_' gets its original value back when the block ends. Could you write 'local unlink $file;' and have the file delete for the duration of the function call? Could you do this with something less destructive like 'local chdir $other_dir;'? (Reddit) |

by brian d foy (BDFOY) Brian shows his actual path through a problem rather than hiding all his failed experiments. The negative results are just as valuable. - Agreed! |

by Gabor Szabo (SZABGAB) There are several modules that provide URL routing service, but if you'd like to see how they might work behind the scene, this article explains it. Oh and in case you are not familiar with the jargon, 'URL routing' means mapping URLs on your server to function calls that will serve the requested page. |

CPAN
|
by Neil Bowers (NEILB) Neil suggests that CPAN distributions that have both Makefile.PL and Build.PL mean trouble and one should not have both. (If the generated Makefile.PL is a perfect replacement of the Build.PL then your users really don't need both.) There is even some history lesson in the comments. |

by Olaf Alders (OALDERS) "Sponsoring MetaCPAN makes perfect sense for Bytemark. It has the potential to save us weeks of developer time by helping our developers locate modules not included in the Perl standard distribution. Large Perl programs can use many modules, from those that interface with SQL databases to simple utilities." |

Perl
|
by brian d foy (BDFOY) The first Perl 5.22 release candidate is out and there are some new operators and many enhancements to regular expressions that look interesting. |
|
|
by Ricardo Signes (RJBS) A feature almost no one has ever heard of, that a simple call to 'open' can create a temporary file. It will even unlink the filename immediately which means an attacker cannot find the temporary file. |

"This is a story about a significant new optimization to the Perl interpreter. It is a story about battling code complexity. And it is a story about wanting to have our cake and eat it too.". You also get a link to PerlGuts Illustrated that in itself is a great resource. |
|
by brian d foy (BDFOY) The 3-argument form of 'open' was added to Perl 5.6 to protect our code from attacks. This is quite well known. The question remained though: How does Perl open filenames when we use the diamond operator in a while loop? That was still vulnerable to the same kind of attacks. Using the new operator you can make your code safer. |
