No More Categories

I’ve removed the per-category Atom feeds from the sidebar, and I’m going to stop categorizing new entries. There are a couple reasons. First, the three categories are somewhat limiting. My next entry will not fall strictly into the AR-Veg, Personal, or Programming categories. Second, the vast majority of my entries are about programming, and that will probably continue to be true. I realized that most anything I’d categorize as Personal is either trivial or something I don’t want to share on a blog.

New Type Constraint Module for Perl

I recently uploaded a new distro to CPAN recently called Type. The concepts are largely on Moose’s built-in type system, but it’s a standalone distribution. Right now this is all very alpha, and the current release is not intended for use by anyone. I’ve released so people can take a look at critique the design. I’ve tried to remedy some of the problems that Moose’s type system has. MooseX::Types fixes some of these problems but then introduces its own.

Rules of Optimization

For that coworker who won’t stop “optimizing” his or her code, I give you my rules of optimization: Don’t optimize Don’t optimize, I’m serious Don’t optimize without benchmarking first Don’t benchmark without profiling first See rule #1 Edit: A co-worker suggested a step 4.5 of “Take a coffee break”. I don’t like coffee, but I like the spirit of the suggestion. Comments Chas. Owens, on 2012-04-26 07:43, said:

git-age-report

At work we have some git repos that were converted from CVS originally created back in 2002 or so. A lot of the things in these repos is cruft and could be deleted. I wrote a little git command to report the most recent commit date for each thing in the current directory. 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 #!

My LWN Article on the Perl 5 Release Process

I wrote an article for LWN (Linux Weekly News) about the Perl 5 release process a couple weeks back. It was originally behind a paywall but it’s now readable by anyone. Another article I wrote will be published later today. I’ll post a link here once it’s out from behind the paywall. Please consider subscribing to LWN if you like this sort of thing, of course.

Are Perl 5 Committers Increasing?

I feel that Perl 5 activity has increased over the past few years, but is that an illusion? I brought this topic up on the #p5p IRC channel and Nicholas Clark said, “everyone assumes growth. If you look at the ‘committers’ graph on https://www.ohloh.net/p/perl/analyses/latest I don’t think there’s been any marked growth (or reduction) in the past 10 years. Just a lot of noise”. So is he right? I wanted to figure it out.

Netflix Has the Weirdest Categories

I’m going through the Netflix movie rating interface right now rating films & tv shows to try to improve my recommendations. Sometimes after you rate something it asks you how often you watch films of a certain category. Presumably the category the thing you just rated belonged to. Some of the categories make sense, and some are completely insane. I can’t figure out how they could possibly be useful in determining what I like.

The Perl 5.15.6 Epigraph

Today I had the privilege (or punishment?) of releasing Perl 5.15.6, the latest monthly dev release of Perl 5. Part of the Perl release tradition is to include an epigraph with each release. The epigraph is a quote of some sort that goes at the beginning of the release announcement. I can’t find the first epigraph but if I had to guess it must be a quote from Tolkien accompanying one of the releases Larry Wall did.
