Don't miss the next issue!

Hi,

There's definitely a growing buzz around Perl 6, as we get closer to Larry's talk at FOSDEM on 1st Feb, with a great-looking Perl (5 and 6) line-up the day before.

357 people have signed up for the CPAN pull request challenge. Thank you to all the CPAN authors who are being so helpful and supportive towards the PR crew, many of whom are working on their first-ever pull request.

Editor #3, Neil

Advocacy

Perl Already Won Tweet Facebook Google+
by Tudor Constantin (TCONST)

An impassioned support of Perl from Tudor, in response to the Why Perl Didn't Win post from August last year. Tudor explains why Perl works for him. And that's what it comes down to I think: we're all wired differently, and some programming languages match our wiring better than others. YMMV.

by Dave Jacoby (JACOBY)

There are lots of different ways to show code samples in a blog post. Dave's current standard is to put the code in a gist, then embed that in the blog post, even if it does require Javascript to be enabled in the reader's browser. What's your preferred approach?

Conventions

What should be in a CPAN distro README? Tweet Facebook Google+
by brian d foy (BDFOY)

brian wonders whether README files are still needed these days, and if so, what should be in them? There are several conventions on CPAN, some dists just have a copy of the main module's doc, others have a summary, and yet others have installation instructions. Add your thoughts in the comments (if you can!).

What Doesn't Seem Like Work? Tweet Facebook Google+
by Paul Graham

A short essay from Paul, with a key insight: "If something that seems like work to other people doesn't seem like work to you, that's something you're well suited for. For example, a lot of programmers I know, including me, actually like debugging. [...] The stranger your tastes seem to other people, the stronger evidence they probably are of what you should do."
