-* Holger gave a talk about diffoscope at the [mirage.io hack retreat](https://retreat.mirage.io) which resulted in three bugs being filed against diffoscope:
-  - #910540 backtrace when using diffoscope on macOS (brew)
-    - immediatly fixed by Chris.
-  - #910541 diffoscope] diffoscope: filing bugs on diffoscope is cumbersome for non-Debian contributors
-  - #910542 better support for OCaml object files via ocamlobjinfo
+Here's what happened in the [Reproducible Builds](https://reproducible-builds.org) effort between Sunday October 7 and Saturday October 13 2018:
+
+* Holger gave a talk about [diffoscope](https://diffoscope.org/) at the [MirageOS](https://mirage.io/) [hacker retreat](https://retreat.mirage.io). This resulted in three bugs being filed ([#910540](https://bugs.debian.org/910540) (*backtrace when using diffoscope on MacOS*, [#910542](https://bugs.debian.org/910542) (*Please add better support for OCaml object files*), & [#910541](https://bugs.debian.org/910541) (*Filing bugs on diffoscope is cumbersome for non-Debian contributors*).
+
+* In the upcoming week, Chris Lamb will be attending [New York University](https://www.nyu.edu/) to work with students from the *Application Security* course on the topic of reproducible builds.
+
+* Richard Purdie reported that the [Yocto Project](https://www.yoctoproject.org/) now offers [reproducible builds for arbitrary paths and build users](https://lists.reproducible-builds.org/pipermail/rb-general/2018-October/001203.html). This is only tested with `core-image-sato`, an [X-based](https://en.wikipedia.org/wiki/X_Window_System) graphical image but means the core system components are reproducible, providing a solid base that further improvements can be made from.
+
+* [Mes](https://gitlab.com/janneke/mes) (a Scheme-based compiler for our "sister" [bootstrappable builds](http://bootstrappable.org) effort) [announced their 0.18 release](http://lists.gnu.org/archive/html/info-gnu/2018-10/msg00000.html).
+
+* Mattia Rizzolo updated the [Contribute](https://reproducible-builds.org/contribute/) section on [our website](https://reproducible-builds.org/), removing some references from the now-deprecated [Alioth](https://wiki.debian.org/Alioth) Debian service. He also [added a handy link to file a new bug report](https://salsa.debian.org/reproducible-builds/diffoscope-website/commit/d1859e5) on the [diffoscope.org](https://diffoscope.org/) website.
+
+* disorderfs (our [FUSE](https://github.com/libfuse/libfuse)-based filesystem that deliberately introduces non-determinism into filesystem metadata) version `0.5.4-2` was [uploaded to Debian unstable](https://tracker.debian.org/news/995207/accepted-disorderfs-054-2-source-into-unstable/) by Holger Levsen. It [included contributions already covered in previous weeks](https://salsa.debian.org/reproducible-builds/disorderfs/commits/debian/0.5.4-2) but also include some fixes to the the `debian/watch` file ([1](https://salsa.debian.org/reproducible-builds/disorderfs/commit/494a411), [2](https://salsa.debian.org/reproducible-builds/disorderfs/commit/e099a4e) & [3](https://salsa.debian.org/reproducible-builds/disorderfs/commit/4c803a4)) and was migrated to [use the new `debhelper-compat (= 11)`](https://salsa.debian.org/reproducible-builds/disorderfs/commit/9c648d3) notation.
+
+* Chris Lamb reviewed 25 Debian packages and 28 were removed in this week, adding to [our knowledge about identified issues](https://tests.reproducible-builds.org/debian/index_issues.html).Chris also added a new [`timestamps_in_episode_files_generated_by_jxc`](https://salsa.debian.org/reproducible-builds/reproducible-notes/commit/0eab9dbe) toolchain issue and [expanded the comments](https://salsa.debian.org/reproducible-builds/reproducible-notes/commit/92bdc5bb) for [`translations_missing_in_desktop_files`](https://tests.reproducible-builds.org/debian/issues/unstable/translations_missing_in_desktop_files_issue.html).
+
+* strip-nondeterminism version `0.043-2` was [uploaded to Debian unstable](https://tracker.debian.org/news/995203/accepted-strip-nondeterminism-0043-2-source-into-unstable/) by Mattia Rizzolo. It [included contributions already covered in previous weeks](https://salsa.debian.org/reproducible-builds/strip-nondeterminism/commits/debian/0.043-2) as well [using the new `debhelper-compat (= 11)` notation](https://salsa.debian.org/reproducible-builds/strip-nondeterminism/commit/deba9e1) and [fixing the `debian/watch` file](https://salsa.debian.org/reproducible-builds/strip-nondeterminism/commit/8c7200b)after moving from the now-deprecated [Alioth](https://wiki.debian.org/Alioth) Debian infrastructure.
+
+Another brief reminder that another Reproducible Builds summit will be taking place between 11th—13th December 2018 in [Mozilla](https://wiki.mozilla.org/Paris)'s offices in Paris. If you are interested in attending please send an email to `holger at layer-acht.org`. More details can also be found on the [corresponding event page](https://reproducible-builds.org/events/paris2018/) of our website.

+
+diffoscope development
+----------------------
+
+[diffoscope](https://diffoscope.org/) is our in-depth "diff-on-steroids" utility which helps us diagnose reproducibility issues in packages) was updated this week, including contributions from:
+
+* Chris Lamb:
+    * [Use `str.startswith(...)` over `str.index(...) == 0` in the Macho comparator to prevent tracebacks if text cannot be found on the line](https://salsa.debian.org/reproducible-builds/diffoscope/commit/56f8215). ([#910540](https://bugs.debian.org/910540)).
+
+* Marek Marczykowski-Górecki:
+    * [Handle FAT filesystems with the `fsimage` comparator](https://salsa.debian.org/reproducible-builds/diffoscope/commit/da3b97a).
+    * [Add a test for FAT `fsimage` comparator](https://salsa.debian.org/reproducible-builds/diffoscope/commit/575f99b).
+
+* Mattia Rizzolo:
+    * Adjust some build dependencies: Add [`linux-image-amd64 [amd64]` to allow the SquashFS tests to run](https://salsa.debian.org/reproducible-builds/diffoscope/commit/225a30b) and [`linux-image-generic`](https://salsa.debian.org/reproducible-builds/diffoscope/commit/b90bd2f).
+    * Adjust "autopkgtest" dependencies: Add [`linux-image-amd64`](https://salsa.debian.org/reproducible-builds/diffoscope/commit/c6d2511) as well as [the optional Python modules](https://salsa.debian.org/reproducible-builds/diffoscope/commit/71eb7e3).
+    * [Move the list of optional Python packages to `setup.py` and have `dh_python3` check the generated `requires.txt](https://salsa.debian.org/reproducible-builds/diffoscope/commit/1e109bc).
+    * [Add a `Build-Conflicts` against `graphicsmagick-imagemagick-compat`](https://salsa.debian.org/reproducible-builds/diffoscope/commit/dc3634e).
+    * [Temporarily drop `{Build,Test}-Depends` for `apktool` and `oggvideotools`; they are not available in `buster` at the moment](https://salsa.debian.org/reproducible-builds/diffoscope/commit/018b7ae).
+    * [Rename `procyon-decompiler` to `procyon`](https://salsa.debian.org/reproducible-builds/diffoscope/commit/d7ec996),
 
-* Richard Purdie [reported on our mailinglist](https://lists.reproducible-builds.org/pipermail/rb-general/2018-October/001203.html) 
-  that the Yocto Project now has reproducible builds for arbitrary paths and
-  build users. This is only tested with our core-image-sato level which is an
-  X based graphical image but means our core system components are reproducible
-  and means there is a solid base further improvements can be made from.

+
+* [Arch Linux](https://www.archlinux.org/)-specific changes:
+    * [Temporarily disable building with `build2` and `build` as the jenkins user](https://salsa.debian.org/qa/jenkins.debian.net/commit/e76b96c6). This was an attempt to diagnose a path-variation issue.

+    * [Improve reminder regarding priorities](https://salsa.debian.org/qa/jenkins.debian.net/commit/a2f215a0). (!)
+
+In addition, Mattia Rizzolo performed some node administration ([1](https://salsa.debian.org/qa/jenkins.debian.net/commit/c8731d91), [2](https://salsa.debian.org/qa/jenkins.debian.net/commit/daeeb033)).
