SHA2017: hacker conference/camp videos are up

SHA2017 is on today (it started over the weekend and ends tomorrow) and it is a hacker conference and camp.

Most of the conference videos are up on Youtube and they are very informative and fun. There are a lot of good talks. I’ve picked a few to showcase here but you should check out the whole playlist of SHA2017 videos.

Decentralize! Self-hosting in your own home using Sovereign

In the Decentralize! talk, the software Sovereign is explored and shown to be a good way to set up your own personal cloud and host your own services and data. Sovereign is a set of playbooks that can be run to install the software on a server that you run. It’s similar to the Freedom Box project.

The software you can self-host with Sovereign is:

  • Dovecot, Postfix and Roundcube for email servers and a webmail interface
  • Jabber/XMPP messaging server with Prosody
  • RSS reader
  • VPN server with OpenVPN (FreedomBox also can do this)
  • Git code repository hosting

LinkedIn releases as free/open source software

LinkedIn has released, a JSON framework for implementing REST, under the Apache License version 2. It’s made for the Java programming language and the code is on github.

The blog post is a great example of one way for an organization to announce the release of a free/open source project. It describes the purpose of the software, the features that it has, the functionality that it provides, and they also give some details about their internal uses of other free/open source software.

In particular, they tell us exactly how long they’ve used this software they’re releasing which gives us confidence that the code meets LinkedIn’s high standards:

We’ve been using for well over a year at LinkedIn. All our new services are built using it and we’ve converted many of our pre-existing services over. We think it’s so important to have a uniform set interfaces that represent our data that we’re aggressively migrating all, yes all, our services to And we’re already well into this transition with many core services that power our site using, including people following, our recommendation engine systems and the network update stream on the homepage.

It also gives us confidence that they won’t abandon the project a few months after releasing it. This increases the chances of a community of developers forming around the project.
