Demanding software professionalism

Miscellany

“Uranus is not a naked–eye object under any circumstances.”

Copernicus’ motivation was religious, not scientific! Galileo looked at the phases of Venus to determine its orbit in relation to Sol.

A Common .ruby-version File For Ruby Projects

Background

I've been using this technique in most of my Ruby projects lately where Ruby versions are required:

Create .rbenv-version containing the target Ruby using a definition name defined in ruby-build (example below). These strings are a proper subset of RVM Ruby string names so far...
Create .rvmrc (with rvm --create --rvmrc "1.9.3@myapp") and edit the environment_id= line to fetch the Ruby version from .rbenv-version (example below).

Today I learned about another Ruby manager, rbfu, where the author is using a similar technique with .rbfu-version.

ruby-1.9.3-p327 cumulative performance patch for rbenv

This installs a patched ruby 1.9.3-p327 with various performance improvements and a backported COW-friendly GC, all courtesy of funny-falcon.

Requirements

You will also need a C Compiler. If you're on Linux, you probably already have one or know how to install one. On OS X, you should install XCode, and brew install autoconf using homebrew.
