Confirmed presentations¶

Topic	Time and dependencies	Status	Rationale
Replicant history: WIP source code			* Has some context that might be useful for new Replicant contributors * Has information on the relationship between Replicant and GNU/Linux
Porting AOSP for a new device	Should be in the beginning / before technical talks. Can be after Replicant history presention.
Replicant and bootloaders: Source code pdf			* The Galaxy SIII (and similar devices) bootloader status is complicated and relevant to Replicant 9
Replicant and modems: * Source code * Introduction pdf * Samsung IPC PDF * oFono based Java RIL pdf			* Meant to enable new contributors to work on the modem part
Discussions on the bootloader situation on the Galaxy SIII and similar smartphones	After the talk on the bootloaders
Discussions on minimal requirement to accept a device in Replicant: * Do we still accept devices with modems that are not isolated? * Do we have plan to require free software bootloaders? * Do we require replacable batteries?	After the talk on modems and bootloaders
Discussions on the future of Replicant: * Which devices do we target * Do we continue focusing on devices with signed bootloaders * Allwinner tablets, upstream Linux, and scalability * Devices with non-replacable batteries	After the talk on Replicant history
Discussion about Upstream components, design choices, and cultural re-appropriation of technology * Upstream * Issues when combining together different build systems (Example: Android build system with Kconfig) * Sharing work with GNU/Linux to enable more political control and cultural re-appropriation of mobile device in the long run, and the risk associated with it * Android upstream anti-features and political design choices * How subjective security is, threat models, and the difference between free software and device maker point of view	Please take a look at Upstream before attending if possible.
Graphics acceleration on Replicant	Should optimally be before Paul leaves

Known schedule constraints:

• On Sunday, the April offices will be closed at 16h, so we need to already have packed everything and left the room at this time.

Still being defined, to be confirmed¶

Precise schedule:
Saturday: 10:00 -> 17:00 (possibly continuing to the night)?
Sunday: 10:00 -> 14:00?
