Announcements

Benchmark JSON::XS vs Sereal vs Data::MessagePack

Celogeek is working with Redis and so he was looking for a fast way to do data serialization and deserialization in Perl. He checked 3 packages: JSON::XS and Data::MesssagePack provide language-independent data structures, while Sereal is only implemented for Perl. His recommended solution is Data::MessagePack.


CPAN

Curating CPAN one dist at a time

Neil Bowers crossed the line. He managed to get a module he has not written by himself to be removed from CPAN. Some of you will highly appreciate this work, others will detest it as killing a sacred cow. What do you think? Would you like to encourage Neil to keep working on this, or do you think there are other, more effective avenues to improve CPAN?

How and why keep your Changes file in standard form. If you are not a CPAN author, then helping to standardize Changes files could be a simple way to help the Perl and CPAN ecosystem. There are pointers in this post how to see which distributions have Changes files that not according to the spec. Then you can go ahead and help fix those.

Last week there was quite a bit of anger flowing towards Dist::Zilla, its users and author, to which David Golden responded in a harsh way.

Last week I left out these links as I did not want to give a stage for those haters in the original post, but now I feel it might be better to share these.
