-* The Briar secure messenger project [published a blog post](https://blog.grobox.de/2018/building-briar-reproducible-and-why-it-matters/) on why reproducible builds matters.
+Here's what happened in the [Reproducible Builds](https://reproducible-builds.org) effort between Sunday September 9 and Saturday September 15 2018:
 
-* [NixCon program](https://nixcon2018.org/\#program) was published - FIXME: how it relates to rb
+* **The fourth Reproducible Builds summit will take place from December 11th → 13th 2018** at the [Mozilla Office](https://wiki.mozilla.org/Paris). in Paris, France. If you are interested in attending please register by sending a mail to `holger at layer-acht.org`. More details may be found on the [associated event page](https://reproducible-builds.org/events/paris2018/).
 
-* [FIXME systemd](https://github.com/systemd/systemd/issues/10045)
+* The [Scala](https://www.scala-lang.org/) programming language [merged a number of improvements](https://github.com/scala/scala-dev/issues/405) to make the output from its compiler more reproducible. This work is available in the [fifth milestone for the upcoming 2.13.0 release](https://github.com/scala/scala/releases/tag/v2.13.0-M5) and is intended to be [backported to the 2.12 tree](https://github.com/scala/scala/pull/7203).
 
-* [FIXME] vagrant: Call for capable armhf dev board donations, link to image, talk(s), etc.
+* The program for [NixOS](https://nixos.org/)'s [2018 conference](https://nixcon2018.org/\#program) was published this week. NixOS's declarative package manager aims to make package management reliable and reproducible.
 
-* FIXME: reproducible builds summit #4 from Decemeber 11 to 13 2018 at the [Mozilla Office in Paris](https://wiki.mozilla.org/Paris). Please register by sending a mail to holger at layer-acht.org

-* [FIXME](https://salsa.debian.org/qa/distro-tracker/merge_requests/50) "FTBR" instead of "unreproducible"
+* A [number of changes were made](https://github.com/systemd/systemd/issues/10045) to [systemd](https://www.freedesktop.org/wiki/Software/systemd/) in order that it builds reproducibly; the issues were related to the test fixtures embedding the build path.
 
-* [FIXME](https://twitter.com/Graphviz/status/1039632469782396929) (`graphviz -Gstart=1` to use fixed random seed)
+* Johannes Schauer (`josch`) [created a merge request](https://salsa.debian.org/qa/distro-tracker/merge_requests/50) for the [Debian Package Tracker](http://tracker.debian.org/) to address that [our test framework](http://tests.reproducible-builds.org) updated an internal API.
+
+* Chris Lamb reviewed 43 Debian packages, adding to [our knowledge about identified issues](https://tests.reproducible-builds.org/debian/index_issues.html) as well as updating a number of issue types including [adding a note from upstream](https://salsa.debian.org/reproducible-builds/reproducible-notes/commit/d0e741c1) on the `graphviz_nondeterminstic_output` issue [via a Tweet](https://twitter.com/Graphviz/status/1039632469782396929) adding adding a new [`randomness_in_pdf2htmlex_html_output`](https://salsa.debian.org/reproducible-builds/reproducible-notes/commit/1ab80af7) toolchain issue.

+diffoscope development
+----------------------
+
+Chris Lamb made a large number of changes to [diffoscope](https://diffoscope.org), our in-depth "diff-on-steroids" utility which helps us diagnose reproducibility issues in packages:
+
+    * [Ensure Debian substvar generation is deterministic regardless of installed packages](https://salsa.debian.org/reproducible-builds/diffoscope/commit/889e4bf). ([#908072](<https://bugs.debian.org/908072]))
+    * [Fix testsuite under LLVM >= 7.0](https://salsa.debian.org/reproducible-builds/diffoscope/commit/f29fdd9). ([#908074](<https://bugs.debian.org/908074]))
+    * [Disable binwalk's own user configuration for predictable results and to ensure it does not create (!) unnecessary directories, etc.](https://salsa.debian.org/reproducible-builds/diffoscope/commit/075acf2). ([#903444](<https://bugs.debian.org/903444]))
+    * [Clarify distinction between tools (eg. gpg) and packages (eg. gnupg) when generating Debian substvars](https://salsa.debian.org/reproducible-builds/diffoscope/commit/d57dba3).
+    * [Don't print GPG output to the console](https://salsa.debian.org/reproducible-builds/diffoscope/commit/3350968).
+    * [Ensure we return bytes objections from Command.filter to prevent LLVM-related tracebacks](https://salsa.debian.org/reproducible-builds/diffoscope/commit/68f3bdd)
+
+These changes were then [uploaded as diffoscope version `101`](https://tracker.debian.org/news/987527/accepted-diffoscope-101-source-all-into-unstable/).
+
+
+tests.reproducible-builds.org development
+-----------------------------------------
+
+There were a number of updates to our [Jenkins](https://jenkins.io/)-based testing framework that powers [tests.reproducible-builds.org](tests.reproducible-builds.org) by Holger Levsen this month, including:
+
+* [Use `amd64` kernels on all `i386` nodes](https://salsa.debian.org/qa/jenkins.debian.net/commit/0fef9342). ([#875990](<https://bugs.debian.org/875990]))
+* [Prevent failures if artifacts cannot be deleted](https://salsa.debian.org/qa/jenkins.debian.net/commit/45238c46).
+* Detect build failures due to [invalid characters in package relations](https://salsa.debian.org/qa/jenkins.debian.net/commit/f0ebaa44), [download problems](https://salsa.debian.org/qa/jenkins.debian.net/commit/051e3667), [Git problems](https://salsa.debian.org/qa/jenkins.debian.net/commit/c05dbbda), etc.
+* [Stop complaining about wrong MTU on IRC](https://salsa.debian.org/qa/jenkins.debian.net/commit/40f79b5b).
+* Update the [build variation documentation](https://tests.reproducible-builds.org/debian/index_variations.html) to reflect [we're currently doing fewer kernel variation tests](https://salsa.debian.org/qa/jenkins.debian.net/commit/4bb73336).
+* [Force `amd64` kernel installation on the `i386` architecture](https://salsa.debian.org/qa/jenkins.debian.net/commit/8a82f593).
