* Eric Myhre [posted about the developer of Dwarf Fortress reporting](https://lists.reproducible-builds.org/pipermail/rb-general/2019-February/001473.html) some "butterfly-effect style" bugs in deterministic world generation in a post titled [*Reproducible builds: it's not just for compilers, it's for dwarfs too. And their entire universe...!*](http://www.bay12games.com/dwarves/#2019-02-21).
* Holger Levsen posted an update after he calculated that [Debian is 54% reproducible in practice](https://lists.reproducible-builds.org/pipermail/rb-general/2019-March/001479.html). This also revealed that 12% of all binary packages in buster/amd64 are [unreproducible because they were built by binNMUs](https://bugs.debian.org/894441).
