# Presentation
## Me

* a tiny bit Debian contributor
* Tails contributor (doc, bug triaging, community stuff, user support,
  reports writing, press, and speaker sometimes :))
* not a developer. I know about Tails design and plans, but don't ask
  implementation questions :)

* <debian@solveig.org>

## Tails

* The Amnesic Incognito Live System:  <https://tails.boum.org>
   - Live system (USB, DVD, SD card)
   - use the Internet anonymously, circumvent censorship: all
     connections to the Internet are forced to go through the Tor
     network
   - leave no trace on the computer you are using unless you ask it
     explicitly
* works on (almost) any x86 computer
* based on Debian ♥

# Debian: our upstream

## Relationship to Debian

* Debian is our "base" and we add some Tails-specific things
* we try to keep this changes (the "Delta") as small as possible because:
   - it's work to maintain it and we're few people
   - it's better if everybody benefits from our improvements
* ... and we succeed: less modified packages in Tails/Wheezy than in
  Tails/Squeeze, will be even better in Tails/Jessie
* Debian is a great upstream :)

## What did we do upstream?

* AppArmor (Ulrike did a OPW in Debian for it)
* libvirt
* Seahorse
* fix OTR downgrade → v1
* various Debian things (including Debian Live)

## What we did not do internally

... despite pressure:

* grsecurity
* compile-time hardening

## What we did internally

... and are in the process of sharing:

* OpenPGP applet
* erasing memory on shutdown
* testing framework (cucumber, sikuli, libvirt)

# Contribute to Tails by contributing to Debian

## In Debian

* We use usertags in Debian's bugtracker <https://bugs.debian.org/>
   - user = <tails-dev@boum.org>
   - tags: whatever we need, that's our namespace (e.g. `crypto-gui`,
     `hardening`, `im`)
   - all our usertagged bugs:
     <https://udd.debian.org/cgi-bin/bts-usertags.cgi?user=tails-dev@boum.org>
   - documentation:
   <https://wiki.debian.org/bugs.debian.org/usertags>

## In Tails: Redmine

# How can I help?

## Help maintain backports

* we use a lot of backports
* e.g. poedit, libvirt, qemu, redmine, monkeysign
* we could use more, e.g. the Xorg stack

## Help maintain packages

* mat
* libgsecuredelete and nautilus-wipe
* OTR-related packages: <https://wiki.debian.org/Teams/OTR>
* anonymity-related packages:
  <https://wiki.debian.org/Teams/AnonymityTools>
* anything Tails relies upon, e.g. GNOME
* anything our infrastructure uses, e.g. libvirt/qemu, Jenkins,
  ruby-rjb, Puppet

## Distribution-wide improvements

* AppArmor support: <https://wiki.debian.org/AppArmor>
* Reproducible builds: <https://wiki.debian.org/ReproducibleBuilds>
* Hardening: <https://wiki.debian.org/HardeningWalkthrough>
* Keep Debian Live development branches good enough for our needs,
  e.g. via automated testing.
* Keep Debian awesome.
