Cartography is subjective. This is a well-known fact borne out year after year, map after map. The early Christian church sponsored T-O maps that showed the world as a metaphorical “body” of Christ. Automotive companies funded city maps from the mid-20th century that plainly showed highways and boulevards with rail and tram lines in diminished […]
Two recent posts on the Thumbtack Engineering blog. How to improve A/B testing with Mixpanel “We enjoy using Mixpanel and enjoy A/B testing. In this post we show how to use Mixpanel’s API and our own open-sourced A/B testing statistics package to easily create A/B tests in Mixpanel.” Know your latency: a simple hack using […]
Thumbtack eats amazing food, but it’s not by accident. Eating lunch together is the single most important culture-building activity we do. Some of the rules include “Have a weekly all-hands dinner”, “Hire a chef”, and “Don’t buy vending machines.” Building a healthy food culture keeps everyone happy and healthy. Read the full story.
The Chez Panisse Foundation is supporting an initiative to make good, local food a part of every school: the Edible Schoolyard. The first edible schoolyard was established at the Martin Luther King, Jr. Middle School in Berkeley, and it has proven to be radically successful. This summer, the Foundation is spreading awareness about the program […]
Cross-posted from the Thumbtack engineering blog. I recently released an open-source mapping toolkit called Rotary Maps that helps you make realtime maps on top of Google Maps v2 or v3. It also supports making maps in a simple DOM element if you don’t care for Google Maps. Check out the full post at the Thumbtack […]
These maps are fascinating. Have you ever wondered why state or county or city boundaries are drawn where they are? It turns out that administrative and government boundaries are consistent with trends in human relationships; that is, people associate most with others in the same government-defined region. To investigate the geography of human relationships, a […]
A comparison of the Linux call graph hierarchy with the E. coli regulatory network. Researchers at Yale discovered that the Linux control structure is top-heavy, with a few common modules reused often. E coli, by contrast, has limited central control with many specialized “workers” at the bottom of the hierarchy.
In the tradition of Notes on the Synthesis of Form, Frederick Brooks takes aim at the problem facing every engineer and designer: how do you architect and build a complex system? The question is especially pertinent to computer scientists and programmers. Included here are a few notes and observations from the book.
The most recent release of Cartographer.js supports county-level choropleth maps. This was the number one requested feature for Cartographer and I am delighted to finally be able to offer it in an official package. Counties are stored with efficient polygon encoding, and are easily referenced by name.
