Welcome to a new week with a couple of fun tasks "Max Str Value" and "Encrypted String". If you are new to the weekly challenge then why not join us and have fun every week. For more information, please read the FAQ.
Corion mentions a number of places where things can be improved. I am surprised that the whole process is not fully automated yet. I mean some of the brightest people in the Perl community work on the core of perl.
Gwyn built mojoeye, a tiny Perl app to run system and security checks across their internal Linux hosts.
Features of Plack-Handler-H2: * Full HTTP/2 spec via nghttp2; * Non-blocking via libevent; * Supports the entire PSGI spec; * Automatically generates self-signed certs if none are provided as args;
Laurent is looking for help with Python and Java for an article series he is writing. Send him an email!
An excellent writeup on the process of optimization. Basically saying: don't do what you don't have to. This is specifically about optimizing OOP systems in Perl. Feel free to comment either on the bpo version of the article or here.
