We'll update you on what's going on with Tor onion services, aka Tor hidden services.

In the past, onion services were mostly run by people who wanted to set up a website that somebody else wanted to shut down. Increasingly, people are recognizing that onion services are much more broadly useful: they are about providing more security to users, not hiding websites. Over the last year or so, Facebook set up an onion service to let their users reach Facebook more securely, the IETF officially designated '.onion' as a reserved domain, we've been talking to the "Let's Encrypt" folks about giving an onion address to every website, some neat new apps are coming out that use onion services (like decentralized chat), and more. We also have some actual stats on hidden services: https://blog.torproject.org/blog/some-statistics-about-onions At the same time, we've been working on next-generation onion services. We'll explain why they greatly improve both security and scalability.

USE OTR (USable Encryption with OTR) is an organisation with a simple goal: improving security, usability and encryption of IM software. This talk will outline our organization, the ecosystem of Off The Record Messaging (OTR) and how to start loving end-to-end encryption.

We are an organisation that works on security, encryption and usability of open source instant messengers (IM).

One key aspect is to have developers, resources and funds available to maintain OTR software over time and thus making them sustainable, up-to-date and secure. While we have already started collaborating with the LEAP project, we want to extend our network and reach out to more people. By developing safer, usable encryption instant messaging tools we believe that it directly supports freedom of speech and expression worldwide.

Following this, we will explain what "Off The Record Messaging" is, the current state of the ecosystem around it. We want to raise awareness about the importance of using end-to-end encryption and bring the open source community together to help with this endeavour!

In the past, a lot of effort has been invested in high performance kernel tracing tools, but now the focus of the tracing community seems to be shifting over to efficient user space application tracing. By providing joint kernel and user space tracing, developers now have deeper insights into their applications. Furthermore, system administrators can now put in place a new way to monitor and debug systems using a low intrusiveness tracing system, LTTng.

This presentation explains how LTTng can be used as a powerful development and debugging tool for user space applications taking advantage of this year's exciting new features such as network streaming and snapshots. It demonstrates how open source developers and hackers can use LTTng kernel and user space tracers to create powerful logging systems and easier debugging, thus greatly improving development and maintainability of their project(s).

Finally, this talk concludes with the future work we will be doing on LTTng, and how the community can help with improving the project from feedback to very valuable contributions.
