Favorite Vim Options: directory
I was thinking about Vim configuration recently, and I wanted to point out one of my favorite Vim options. Have you ever
been working in a Git repository and run a git status, only to encounter a series of swap files in the output? How about having
an automated deploy refuse to run because it found an unstaged file in the working directory (you guessed it; a Vim swap file)?
In a response to this annoyance, I've had colleagues recommend disabling Vim's swap file feature entirely! I'd like to propose an
alternative: my friend, the directory option.

Oh My Glob
My recent posts on the inner workings of perl have made me reflect on some of the more advanced, lesser-known parts of the Perl language. One of these features that I'd like to talk about today is the typeglob.

Perl 5 Internals - Part Four
The first three installments of this series covered Perl's core data types: scalars, arrays, and hashes. This final installment will cover something a bit different: the optree. Those of you who are familiar with compiler concepts are no doubt familiar with the notion of an abstract syntax tree (known as an AST for short). The optree is perl's take on the AST: it's something similar to, but not entirely the same as, an AST. Before we begin looking at the optree, I recommend reviewing the "Subroutines" and "Compiled code" sections of perlguts, as well as looking at perlcall. It is by no means required, but it might make digesting this content a little easier.

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!
