Git Large File Storage (LFS) is an open source Git extension aimed to better "integrate large binary files such as audio samples, datasets, graphics, and videos" into a Git workflow, says GitHub.
Popular configuration mechanisms like conf.d pose multiple problems when trying to converge system configuration using configuration management tools. Ish-Shalom proposes five design principles for configuration that prevent those problems. The core ideas being the use of a configuration API and the separation of configurations based on the type of system updates they require.
Open Source project hosting sites like SourceForge, Codehaus and Google Code inspired developers to share their code for projects not associated with a foundation like Apache or Eclipse. Over the past few years, these hosting sites have been superseded by GitHub, to the extent that they are closing down over the next year. InfoQ looks back at their contributions and into the future.
Atlassian's popular source code hosting site Bitbucket launched Snippets for teams, a collaboration oriented solution to "create and manage multi-file snippets of all kinds". Snippets can be created via drag and drop, owned by a user or a team and optionally shared publicly. They are backed by Git or Mercurial repositories and can be managed via a REST API.
