Total Cost of Ownership (TCO) can be used for investment decisions and financial benefit analysis. When applied to software it covers the initial development costs and subsequent maintenance costs until phase out of a product. TCO can support architectural decisions and management of technical debt.
Continuous Integration can help to find integration issues earlier and to visualize the status of the build to all involved. Integration problems can be detected at build-time in stead of run-time during testing and teams can get immediate feedback on changes that they made and on the impact on components that are developed by other teams.
In an attempt to bring Android, iOS, classic Windows and web applications on a single platform and make them available through the Windows Store, Microsoft has launched four projects, also knows as Universal Windows Platform Bridges, namely: Astoria, Islandwood, Centennial, and Westminster.
Google has open sourced Jsonnet, a configuration language that supersedes JSON and adds new features without breaking backwards compatibility: comments, references, arithmetic and conditional operators, array and object comprehension, imports, functions, local variables, inheritance and others.

Atlassian recently released Stash Data Center, a highly available and horizontally scalable deployment option for its on-premises source code and Git repository management solution Stash. New nodes can be added without downtime to provide active-active clustering and instant scalability.
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 Over the past few years, these hosting sites have been superseded by GitHub, to the extent that they are closing down over the next year.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.
With all the news about git in Visual Studio and Team Foundation Server, it isn’t hard to see why many developers think that TFVC, the centralized version control inside TFS is a dead product. Brain Harry, the Product Manager for TFS, recently addressed these concerns.
Codetrails has released Codecity for Eclipse, which provides a visualisation of Java packages and classes in a 3D visualisation to identify where code can be improved. InfoQ evaluates the plug-in.
