Adding IPv6 connectivity support to the Dropbox desktop client

Computers on the internet are uniquely identified by an IP address. For decades the world has used Internet Protocol version 4 (IPv4), which allows for about 4 billion unique addresses.

Layers and layers of workarounds have been built to mitigate the problem. The current protocol—Internet Protocol version 6 (IPv6)—fixes various problems with IPv4; it has a significantly…

Earth Deserves Better Than TV Coverage of Climate Change

As I write this, a day after Earth Day 2017, the memory of hundreds of “Marches for Science” and in particular, a CNN report on climate change makes me wonder whether the medium of television is more harmful than helpful in bringing the attention of the general public to complex issues of public interest.  These thoughts are stimulated by an online article and video clip of the report, which featured an exchange between famed popularizer of science Bill Nye the…

Building instant image feature detection – Pinterest Engineering – Medium

Kent Brewster | Pinterest engineer, Product Engineering Last month we launched visual search in our browser extension for Chrome.

The depth of this complexity only increases with the age of the business, leaving a private cloud operator saddled with legacy hardware,…
