Here's what happened in the [Reproducible Builds](https://reproducible-builds.org) effort between Sunday February 10th and Saturday February 16th 2019:
*There was [a brief update from the Debian Ruby maintainers](https://bugs.debian.org/848660) on whether the language might need to strip `-fdebug-prefix-map` from the tools used to build extensions.
*`strip-nondeterminism` is our tool that post-processes files to remove known non-deterministic output. This week, Chris Lamb adjusted its behaviour to deduplicate hardlinks via `stat(2)` before processing to avoid issues when handling files in parallel; as the per-filetype handlers are yet currently guaranteed to be atomic, one process could temporarily truncate a file which can cause errors in other processes operating on the "same" file under a different pathname. This was thus causing package build failures in packages that de-duplicate hardlinks in their build process such as the [Debian Administrator's Handbook](https://debian-handbook.info/)([#922168](https://bugs.debian.org/#922168)).

* On [our mailing list](https://lists.reproducible-builds.org/listinfo/rb-general), Holger Levsen [re-raised a question](https://lists.reproducible-builds.org/pipermail/rb-general/2019-February/001446.html) regarding uploading the "official" `.buildinfo` files to [buildinfo.debian.net](https://buildinfo.debian.net/).
* Jelle van der Waa fixed some spelling mistakes on the [reproducible-builds.org](https://reproducible-builds.org) project website. [[...](https://salsa.debian.org/reproducible-builds/reproducible-website/commit/dea014e)]
* On Tuesday 26th February Chris Lamb will speak at [Speck&Tech 31 "Open Security"](https://www.eventbrite.com/e/specktech-31-open-security-tickets-53503912643) on Reproducible Builds in Trento, Italy.

* 6 Debian package reviews were added, 4 were updated and 16 were removed in this week, adding to [our knowledge about identified issues](https://tests.reproducible-builds.org/debian/index_issues.html).
