About two years ago, a significant event happened at Stack Overflow: a new system, named Providence, was released. Providence would allow us to tell which technologies a visitor is interested in, and measure the “fitness” between a visitor and a job. The release of Providence marked a stepping stone in Stack Overflow’s continuous effort to be “smarter” and invest in data science, and it was only the beginning.

This morning, a popular Stack Overflow question hit a major milestone:

As of today, Stack Overflow now deploys HTTPS by default on StackOverflow.com — as well as the hundreds of Q&A communities that make up our Stack Exchange network. We now redirect all traffic to https://, and Google links will change over the next few weeks.

It’s been four years since the Spanish site was proposed in Area 51 and we’ve just proven once more that international sites offer much to the users of those communities and to our network as a whole.  I would like to announce that the Stack Overflow en Español community has graduated and will form a part of the network of sites as a full-fledged community for developers and coders around the world!

In honor of Google I/O 2017 and the launch of the official Stack Overflow mobile app, we on the Stack Overflow Insights team are sharing a look at the fast-paced history of mobile application development.
