℞ 4: Characters and their numbers Do you need to translate a codepoint to a character or a character to its codepoint? The ord and chr functions work transparently on all codepoints, not just on ASCII alone—nor in fact, not…
℞ 3: Declare source in UTF-8 for identifiers and literals Without the all-critical use utf8 declaration, putting UTF‑8 in your literals and identifiers won’t work right. If you used the standard Perl Unicode preamble, this already happened. If you did,…
℞ 2: Fine-tuning Unicode warnings It’s easy to get Unicode wrong, especially when handling user input and dealing with multiple encodings. Perl is happy to help you detect unexpected conditions of your data. Perl is also happy to let you…
To handle Unicode effectively, always decompose on the way in, then recompose on the way out.
Tom Christiansen demonstrates the bare minimum feature set necessary to work with Unicode effectively in Perl 5.
Thanks to Lars Dɪᴇᴄᴋᴏᴡ for coordinating entries into the Plat_Forms 2012 web development contest. This annual contest pits some of the best developers of frameworks and languages against each other to solve real problems. Perl developers have participated for several…
Scott Wiersdorf shows how to write a little bit of Perl to build an automated voice mail menu with Twilio’s API.
Perl can make your phone ring. Scott Wiersdorf demonstrates how to use Twilio’s API to make and receive phone calls and to automate SMS, all from Perl.
In this excerpt from Programming Perl 4e, Tom Christiansen demonstrates that, in a Unicode world, sorting correctly can be trickier than you think.
Christian Walde demonstrates that even ActivePerl users on Windows can use CPAN-out of the box.
Perl 5.14 provides a new feature called unicode_strings to improve Unicode string handling.
Perl 5.14 loads IO::File on demand for autovivified filehandles.

Lars Dɪᴇᴄᴋᴏᴡ has sent out a call for attention for the 2011 Perl QA Hackathon: The Perl QA hackathon 2011 is taking place from Saturday, April 16th to Monday, April 18th 2011 in Amsterdam, The Netherlands. Attendance is gratis. We…
In this edited excerpt from the SDL Perl manual, lead developer Kartik Thakore walks through a non-game application of SDL and Perl, building a music player with visualizations in just a few lines of code.
Why do so many web applications have the same components, yet so few actually share those components as libraries? Perhaps the philosophy of building web frameworks is the culprit. Zbigniew Lukasiak’s WebNano is an attempt to solve that problem.
Thanks to Lars Dɪᴇᴄᴋᴏᴡ for sending along this notice about the Plat_Forms 2011 web development contest. Unlike other comparisons of programming languages (such as the great unmaintainable speed-tweakers micromeasurement contest and This Is Odiously Bad Empiricism), Plat_Forms features real teams…
