General Rules

Commit messages must have a subject line and may have body copy. These must be separated by a blank line.
The subject line must not exceed 50 characters
The subject line should be capitalized and must not end in a period
The subject line must be written in imperative mood (Fix, not Fixed / Fixes etc.)
The body copy must be wrapped at 72 columns
The body copy must only contain explanations as to what and why, never how. The latter belongs in documentation and implementation.

Elixir installation guide

Version numbers should be the ones you want. Here I do it with the last ones available at the moment of writing.

The simplest way to install elixir is using your package manager. Sadly, at the time of writing only Fedora shows the intention to keep its packages up to date. There you can simply sudo dnf install erlang elixir and you are good to go.

Anyway, if you intend to work with several versions of erlang or elixir at the same time, or you are tied to a specific version, you will need to compile it yourself. Then asdf is your best friend.

On the business of e-mail clients

I have been following the whole debate around this e-mail client (Sparrow) getting bought by Google. E-mail clients and the e-mail business are something close to my heart as I have once spent considerable amount of time on my own e-mail client.

People seem to be pretty upset about this acquisition because one of their favourite apps apparantly wont be updated anymore in the future, which is understandable. But lets look at this discussion from the other side: e-mail clients as a business.

Now I don't know the facts, nor do I know the good people at Sparrow. But I do know this space very well and know the facts about the space. My own Inbox2 desktop (for Windows) had about 500.000 downloads and is still being downloaded today (I stopped working on that about 2 years ago). I am assuming Sparrow did much better then this but still the essentials would remain the same.

	Based on feedback from ChemicalR I'm cross posting all the things I've bookmarked in reguards to planet rendering here in the code forums.

Most of these methods are now obsolete and replaced with faster methods and gpu shaders. His [url=http://http.developer.nvidia.com/GPUGems2/gpugems2_chapter16.html]atmospheric scattering[/url]method is still used often due to its relative simplicity, but it only produces earth atmospheres.

It is based on a cube with mesh texture and normalizes the vertex points into a sphere. The advantage to this method is that conventional terrain LOD methods, often used in first
