The Linux Foundation launched the Civil Infrastructure Platform (CIP) project to develop base layer, open source industrial-grade software for civil infrastructure projects, the CIP supports electrical and power grids, railway, shipping, and transportation systems, among other applications that are imperative to human life. Currently, there're several active workgroups in this project, such as Linux kernel, real-time, testing, security, and software update.

Kotlin is not only for mobile development but also for backend (it could be used everywhere actually!). In JetBrains, we build Ktor framework for backend development such as website, API, microservice. In this talk, I will introduce what Ktor is, how to integrated with Exposed SQL library, demonstrate how to build a RESTful API service in just a few lines of code. After listening to this talk, you will learn how to build API with Ktor rapidly.

I will discuss how I apply some ideas from software package repositories into a business/brand database that stores a list of businesses of  Hong Kong.

I will be introducing a new open source project written by myself for 4 years named "Open ArOZ Online" (OAO), which is a light weight user orientated cloud architecture for the Raspberry Pi series. It support IoT functionality, media streaming and more with an easy to use Web Desktop User Interface just like a normal operating system. Expected to be completed and release on Github in late April to early May. This talk will be a quick introduction to such a system, a quick hand-on tutorial and basic introduction on the architecture of the system modular design framework.

We all love open source software and open culture, and of course we all want to contribute to and leverage the power of open source in our work. However when it comes to working in a startup, openness is often sacrificed to give way to work efficiency and business logic. In this talk I will talk about some of my experience(and failures) to be open source, and how our company is trying to be open by default without too much efficiency overhead.

LibreOffice is a successor of OpenOffice.org and full-featured open-source office software. It is a large application written in 9 million lines of C ++, with an estimated 200 million users worldwide.  It has been known as a desktop application, but for resenting years the "online" version, which allows edit documents via modern web browsers, has also be developed, and mobile versions will also be available soon.

Problem

To be honest, none of the online teaching solution meets the real need of running online lab session. All existing online teaching solutions are just for online meeting or one direction broadcast! Teachers are 100% no way to know your students are really working on their exercise at home or they are just open the online meeting apps, and then doing other stuff!

Watch Trouble present a three-day workshop on ZFS in however little time the conference organisers were willing to allocate for it! 

We'll cover topics from filesystem reliability over snapshots and volume management to future directions in ZFS.
