I have a problem managing projects I'm interested in but don't have time for. For example, the CLI for generating slack alerts I posted about last year. Not really a priority, but helpful and not that complicated. I sat on that project for about a year before I ...

I finally got a chance to scratch an itch today.

At Mozilla, we're still relatively early in our data science journey. As such, we're always evaluating new tools to improve our analysis workflow (jupyter vs. Rmd), or make our infrastructure more usable (our home-rolled ATMO vs. databricks), or scale our knowledge (knoledge-repo. vs. gitbook)

Most of these tools ...

I just wrote up a style guide for our team's documentation. The documentation is rendered using Gitbook and hosted on Github Pages. You can find the PR here but I figured it's worth sharing here as well.
