Research on how module authors "negotiate" breaking changes in software package managers

I am a subscriber to module-authors@perl.org and thought I’d repost something written there for the wider community.

Chris Bogart, a postdoc at Carnegie Mellon, is interested in studying how different language-level package managers and repositories handle breaking changes. He has observed that different package management systems have made “very different design choices from each other,” and he would “like to know what the impact of [CPAN’s] design choices are on how you negotiate breaking changes among CPAN module developers when the packages depend on each other.”

If you have released modules on CPAN, and especially if you have thought about making breaking changes to your module, or have made breaking changes to your module, I’m sure you’re ideas would be helpful. If you have had to deal with an upstream author’s breaking changes, I’m sure that would be helpful, too.

These benchmarks seem wrong...

Back in the fall of 2013 I began working on a project called C::Blocks. After some very long detours the project is finally coming to fruition. I recently took it for a spin on a benchmark from the benchmarksgame. The results? Let's just say I was very surprised.

PDL features I'd like to see in Perl 6

I recently asked around #perl6 as to a mailing list where I might discuss PDL features that I'd like to see in Perl 6. Synopsis 9 is supposed to discuss these features, but the PDLish ideas feels like a straight port of PDL, rather than a rethink of what's important. I wanted to discuss things a bit.

The answer was, "Write a blog post." This post contains what I consider to be the essential ingredients of PDL that I think are easily achievable for Perl 6 v1.0. I want Perl 6 to provide an expressive language for writing operations on high dimensional data. I believe that we (and I do include myself) can get this done by Christmas if others can help me out.

How Perl + StickK helped me get organized

The last three months have been some of the most professionally productive months I've had in years. In true Perl fashion, it all boils down to a Perl-related "hack" with StickK.com.

DOIs for Perl Module tarballs, probably

A while back, Mark Fisher wrote about DOIs. As an academic, I asked about how I might cite a DOI for some Perl work. I was recently made aware of two possibilities.
