Media coverage
--------------

* Sylvain Beucler wrote an interesting article about his experiences making software reproducible called [Practical basics of reproducible builds](http://blog.beuc.net/posts/Practical_basics_of_reproducible_builds/).

* Matthew Garrett published a blog post [announcing the Shim review process](http://mjg59.dreamwidth.org/47438.html). One interesting detail in the [current recommendations](https://docs.google.com/document/d/1gHFkhMmn6VVvVQim5YcjJ8uc3xf1JHQnA9f8KSE6qqY/edit?usp=sharing) is that they expect the builds to be "bit-for-bit" reproducible assuming the same toolchain and `gnu-efi`. This currently does not extend to the randomly generated embedded certificate though they also plan to address that soon.

* Holger Levsen gave a talk at the [German Unix User Group's "Frühjahrsfachgespräch"](http://www.guug.de/veranstaltungen/ffg2017/)
  called
  [Reproducible Builds everywhere](http://www.guug.de/adm/ffg-pk/abstracts.html#4_5_2) on March 23rd. [Slides](http://reproducible.alioth.debian.org/presentations/2017-03-24-GUUG.pdf) are available.

* Vagrant Cascadian presented *Verifying Software Freedom with Reproducible Builds* at
  [Libreplanet2017](https://www.libreplanet.org/2017/) in Boston on March 25th.

* Ximin Luo, Vagrant Cascadian and Valerie Young held a workshop called *You,
  too, can write reproducible software!* at
  [Libreplanet2017](https://www.libreplanet.org/2017/) in Boston on March 25th.
