My preferred code style is 2-space K&R. This is intended to provide a justification for this style.

Why K&R?

K&R style has the following properties:

1. Provides symmetric size (in terms of screen space consumed) between the opening and closing syntax of a clode block.
2. Forces no empty or meaningless lines, thereby avoiding artificial distance between related things that should be together.
3. Consumes the minimum vertical space while keeping the opening and closing syntax of a block on separate lines from the content.

libevent vs libuv

Comparing libevent and libuv. My upfront biased: I want to like libevent. However, I want to objectively compare the two and make an informed decision.

What versions are we comparing?

• libevent 2.0.22 (Stable) [2014-01-05]
• libuv 1.8.0 (Stable) [2015-12-15]
