Starting in the spring 2013, I videotaped the lectures for my MATH 676: Finite element methods in scientific computing course at the KAMU TV studio at Texas A&M. These are lectures on many aspects of scientific computing, software, and the practical aspects of the finite element method, as well as their implementation in the deal.II software library. Support for creating these videos was also provided by the National Science Foundation and the Computational Infrastructure in Geodynamics.

Note 1: In some of the videos, I demonstrate code or user interfaces. If you can't read the text, change the video quality by clicking on the "gear" symbol at the bottom right of the YouTube player.

Note 2: deal.II is an actively developed library, and in the course of this development we occasionally deprecate and remove functionality. In some cases, this implies that we also change tutorial programs, but the nature of videos is that this is not reflected in something that may have been recorded years ago. If in doubt, consult the current version of the tutorial.

Lecture 32.75: Learning to use modern tools, part 5b: Version control systems (VCSs), git

Continuing discussions of version control systems, this lecture is about the git system that is widely used today by groups working together on the same code. It differs from Subversion in that there is no single repository, but everyone has one or more repositories and patches flow from one to the other. The lecture discusses the philosophical differences between the two programs and shows some of the common workflows.
Note: There are many other excellent resources out there that introduce git. For example, the excellent Software Carpentry project has this lesson with much more detail than I cover in my video. There is also a video version of this lesson.
