Core

Presenter: Steve Langasek

Track leads: Steve Langasek, Daniel Holbach

• Tuesday

• Creating more Snappy Frameworks: Good discussion about the general definition and understanding of Frameworks. What can be a framework, what should be an app, what other options are there. Received good input from many “customers” of snappy. Things are looking good for Snappy Ubuntu Core being the basis of Ubuntu’s future. Also: bluetooth and connectivity (based on network-manager) landing soon.

• Snap packages for phone and desktop apps: Kyle Fazzari and Alejandro Cura presented their analysis on what it would take to convert the phone from clicks to snaps. A detailed discussion of a plan ensued and will be ongoing for the next weeks.
• Wednesday
• nodejs and libv8 for 16.04

• There’s a general trend to increase dependencies on nodejs, but its long term security support statement is weak. The main use case is building documentation for packages in main using jquery and other js packages. The conclusion is to allow node.js and jquery in main as a build dependency, but not for general use. To do that, pursue archive reorg and change the definition of main vis-a-vis security support instead of having to provide security support for nodejs

• Python3 Only on the images

• Discussed and assigned work items for removal of Python 2 from the desktop, server, and cloud images.  Very close on the latter two (we were there for 15.10 but regressed at the last minute) and we have a good roadmap for the former. https://wiki.ubuntu.com/Python/FoundationsXPythonVersions

• We briefly discussed what happens to /usr/bin/python (nothing!) and how scripts that can run on Python 2 & 3 can work from Precise to Xenial.  No decisions made.

• EFI Capsule and Fallback
• Started to define our story for supporting firmware updates through UEFI.
• Thursday
• Your feedback counts: the Snappy onboarding experience
• Lots of great feedback from all kinds of developer audiences of Ubuntu Core. Will be factored into our documentation and onboarding plans.
• Snappy Developer Community Resources
• We are already using a number of social media and support channels for snappy, so it was time to review them and bring more structure to them. We also decided which presentation/workshop materials we want to provide enthusiasts with, so they can represent Snappy at conferences/universities/LUG meetings out there.
• Porting popular apps/software to Snappy
• We put together a nice list of apps which are often used on Raspberry Pis and other devices. This should help us start a conversation on the mailing list on how we can collaborate to bring the most interesting ones to snappy too.

Show & Tell

Track Leads: balloons, hggdh, David Callé, Laura Czajkowski

Presenter: David Callé

• Tuesday
• Testing Snappy - balloons

• Unity8 Convergence
• Fantastic convergence demo session from Michael Zanetti (Nexus4 + TV) with a lot of questions!
• Snappy Clinic

• Modeling Network Partitions with JuJu

• Demo of Jupsen, a Juju plugin that allows network partitions modeling in a simple way, so you can easily test how your app handles them and guard against failures.
• Matt demonstrated jupsen Network partitions happen, your distributed system needs to be designed to handle them. One of the reasons they39re often not tested is the difficulty in setting up failure scenarios.

• I39d like to show jupsen (https://github.com/mattyw/jupsen). Jupsen is a juju plugin that allows you to model network partitions in a simple way, so you can easily test how your app handles them.

• I will start by giving a brief tour of the commands available. I will then show an app writing to a mongodb replica set during a network partition. I will create a partition that causes lost writes, and demonstrate how you can guard against them.
