How to share a folder with a docker container on OSX

Mounting shared folders between OSX and the docker container is tricky due to the intermediate boot2docker VM. You can't use the usual docker -v option as the docker server knows nothing about the OSX filesystem - it can only mount folders from the boot2docker filesystem. Fortunately, you can work around this using SSHFS.

Eliminating Code Smell With Grunt

by Gavin Lazar Suntop @gvn

Intro

I love clean code. There, I said it. I pride myself on passing strict linting standards and keeping my code easy to read. It's not just a personal proclivity, but a choice I hope benefits other developers.

My general experience with teams has been that code style is something people care about and have strong personal preferences. Typically, at some point people get tired of dealing with inconsistency and a standardization meeting is called. This is, of course, an important discussion to have. The problem that tends to occur is either lack of documentation or lack of enforcement of the agreed upon style. Additionally, new team members or contributors may not have access to a clear set of rules.
