Experiments are releases

Mission Control was a major 2017 initiative for the Firefox Data team. The goal is to provide release managers with near-real-time release-health metrics minutes after going public. Will has a great write up here if you want to read more.

The key here is that the data has to be ...


Desirable features of experimentation tools

Introduction

At Mozilla, we're quickly climbing up our Data Science Hierarchy of Needs 1. I think the next big step for our data team is to make experimentation feel natural. There are a few components to this (e.g. training or culture) but improving the tooling is going to ...


Submission Date vs Activity Date

My comments on Bug 1422892 started to get long, so I started untangling my thoughts here.


From the bug:

We experimented with using activity_date instead of submission_date when developing the clients_daily etl job. We should summarize our findings and decide on which of these measures we'd like to standardize ...


OKRs and 4DX

I feel like I'm swimming in acronyms these days.

Earlier this year, my team started using Objectives and Key Results (OKRs) for our planning. It's been a learning process. I had some prior experience with OKRs at Google, but I've never felt like I was fully taking ...


Evaluating New Tools

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 ...


Documentation Style Guide

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.

Style Guide

Articles should be written in Markdown (not AsciiDoc). Markdown ...


Beer and Probes

Quick post to clear up some terminology. But first, an analogy to clear up my thinking:

Analogy

Temperature control is a big part of brewing beer. Throughout the brewing process I use a thermometer to measure the temperature of the soon-to-be beer. Because I take several temperature readings throughout the ...


Bad Tools are Insidious

This is my first job making data tools that other people use. In the past, I've always been a data scientist - a consumer of these tools. I'm learning a lot.

Last quarter, I learned that bad tools are often hard to spot even when they're damaging productivity ...


Literature Review: Writing Great Documentation

I’m working on a big overhaul of my team’s documentation. I’ve noticed writing documentation is a difficult thing to get right. I haven’t seen any great example for a data product, either. I don’t have much experience in this area, so I decided to review ...


Is moving to the Bay Area worth it?

I came across this article on the front page of Hacker News yesterday. The author argues that Bay Area housing prices may be high, but the salary increase probably makes it worth while. The author pulls together some interesting data to make their point, but I have major issues with ...
