Got frustrated with the complexities of heavyweight build automation/continuous integration tools like Jenkins, Concourse or Buildbot so I built my own in Go . https://gogs.blitter.com/Russtopia/bacillus. Well under 1K SLOC, no JVM or containers required. Config nearly 100% in the launch script itself.

Go is a lean, powerful language that takes a lot of cognitive load off of the developer with rich data manipulation functions and easy to use HTTP/net libs and concurrency. Combined with gopherjs this old-timey embedded programmer finally found a sensible language for both front- and back-end web development.
