Perl 5 Internals - Part Three

In the previous post, we talked about some of the optimizations that perl performs when conducting string and array operations. This time, we'll be diving into how perl implements hashes. But first, a brief clarification...

Perl 5 Internals - Part Two

Welcome back for another exciting episode on the inner workings of the perl interpreter! Last time we covered some of the basic optimizations perl performs on SVs, as well as the consequences of those optimizations. This time, we'll be going over some of the optimizations specific to strings and arrays. I know I said we'd be covering hashes too, but this article is already quite lengthy, and I have enough material on hashes to merit its own article, so look for that information in the upcoming third part of this series!

Perl 5 Internals - Part One

Last week I completed a two-part training at work on perl's internals, led by Yves Orton and Steffen Mueller. We covered some of data structures used by the interpreter, as well as some of the optimizations it uses and the consequences of how those optimizations are implemented. Someone on Twitter asked me if there were any slides available, and unfortunately, the talk was conducted in a very ad-hoc fashion (which actually probably contributed to its success, as the audience was able to propose new areas to cover). However, I did end up taking some notes, so I'm going to summarize those here along with what I remember. A lot was covered in the two sessions, so in the interest of actually getting this information out (I tend not to publish things that I can't write in one sitting), as well as keeping your attention, I'll be publishing them in a series of posts.

Site Facelift

Over the past few weeks, I've been working on giving my site a bit of a facelift. As you can see, the style has completely changed; I decided that the site needed a fresher look. Many thanks to my wonderful girlfriend Michelle for her stylistic contributions!

Playtime

Lately, I've noticed that I've devoted a lot of my time to open source projects or projects at work. While these are important, the kind of work these involve can get a bit repetitive at times, and I haven't really allocated a lot of time for "play" programming. By that, I mean writing things for fun, or experimenting with new things. To quote Albert Einstein:
