Lost in the Desert So, there's a man crawling through the desert. He'd decided to try his SUV in a little bit of cross-country travel, had great fun zooming over the badlands and through the sand, got lost, hit a big rock, and then he couldn't get it started again. There were no cell phone towers anywhere near, so his cell phone was useless.
I do not build database engines.
I build web applications. I see apps with different requirements and different data storage needs. This is a story about one of those times — why we picked it originally, how we discovered it was wrong, and how we recovered. It all happened on an open source project called Diaspora. The project Diaspora is a distributed social network with a long history.
They sent it out to friends and family, and hoped for the best. But they hit a nerve. Diaspora was the first Kickstarter project to vastly overrun its goal. The fallout from that was actually how I first heard about the project. As a result of their Kickstarter success, the guys left school and came out to San Francisco to start writing code.
They ended up in my office. I worked with official clients during the day, then hung out with them after work and contributed code on weekends. They ended up staying at Pivotal for more than two years.
By the end of that first summer, though, they already had a minimal but working for some definition implementation of a distributed social network built in Ruby on Rails and backed by MongoDB.
The main technical difference between Diaspora and Facebook is invisible to end users: The Diaspora infrastructure is not located behind a single web address.
There are hundreds of independent Diaspora servers. The code is open source, so if you want to, you can stand up your own server. Each server, called a pod, has its own database and its own set of users, and will interoperate with all the other Diaspora pods that each have their own database and set of users.
Pods of different sizes communicate with each other, without a central hub. You can follow other users on your pod, and you can also follow people who are users on other pods. Your pod is notified over the API.
You look at your activity feed and see that post mixed in with posts from the other people you follow.
Comments work the same way. Everyone who has permission to see the post sees all the comments, just as you would expect if everyone were on a single logical server.As editor of the Jargon File and author of a few other well-known documents of similar nature, I often get email requests from enthusiastic network newbies asking (in effect) "how can I learn to be a wizardly hacker?".
Back in I noticed that there didn't seem to be any other FAQs or web documents that addressed this vital question, so I started this one.
