Chrome's profiler ("Performance tab) is very useful for measuring JavaScript performance, but what if you want to measure the performance of a custom extension?
For example, what if I would like to profile the following interaction:

- io is a fork of node v0.12 (the next stable version of node.js, currently unreleased)
- io.js will be totally compatible with node.js
- the people who created io.js are node core contributors who have different ideas on how to run the project
- it is not a zero-sum game. many core contributors will help maintain both node.js and io.js

- JSHint
- node-static
- Browserify

O estado da comunidade brasileira de front end
Hoje algo cômico e surreal aconteceu na comunidade FrontEnd Brasil. Algo chocante a ponto de desanimar o mais engajado dos participantes.
Após postar um Gist sobre moment com um código bastante didático, Berger foi rechaçado pelo moderador da comunidade, Jean Carlo Nascimento. Ao notar que o gist era escrito em CoffeeScript, o moderador comentou uma piadinha:
Prefiro usar moment a coffee.
A comunidade não gostou e reagiu, criticando o comentário infeliz e prezando o autor por compartilhar um código útil. Não satisfeito, as agressões sobre o uso de CoffeeScript continuaram.
