Shuah Khan is Senior Linux Kernel Developer at Samsung. The Linux Kernel is one of the biggest open source projects in the world and it is used by devices that we interact with on a daily basis. Shuah explained what an operating system kernel is and how the Linux Kernel is architected to support different types of devices. Shuah also talked about how quality is ensured, how tests are run, and the process of contributing to an open source project. In a project of this magnitude and with contributors all over the world, it is important to have a consistent and effective process in place. I really enjoyed this conversation, and I learned a lot by talking to Shuah.
