Dist::Zilla, Pod::Weaver and bin
Flavio Poletti fights Dist::Zilla and Pod::Weaver in public. And wins! There is a certain value when someone describes the path to the solution and not only the solution. That helps people accept, that they are not expected to come up with a solution out of the blue. It also helps people learning the fine art of problem solving.

Flavio Poletti created a command line tool that can take files and act on their lines as elements of sets to find out union and intersect and even to subtract one from the other. It looks interesting though I'd like to see an explanation of the use case his co-worker had that prompted the creation of this tool.

Parse::RecDescent and number of elements read on the fly
Flavio Poletti explains how he parses some grammar that has parts that are declared dynamically. Sort of changing the rules as you go along. I have a feeling that there should be an easer way to solve this but have not checked it deeply. Maybe you could do it? Maybe using Marpa?

A general profile photo that looks in the camera
Flavio reminds us all that when you put a picture of a person on a slide (or a blog post, or an e-mail), make sure the person does not look away from the text. Either the person on the side should look at the text, s/he should straight ahead. The latter will indicate that the person on the page is interested in the reader.
