+After my [internship last year has ended]({{ site.baseurl }}{% post_url 2017-08-12-internship-ending %}), I naturally became somewhat less active in the Rust community as I could not work on Rust full-time any more.
+Well, for the following months I am going to be back full-time. :)
+Thanks to @aturon, I am able to work as a research assistant for Mozilla during this summer (until the end of November).
+I don't really know what a "research assistant" is, but I am going to continue the work on Rust memory models, and hopefully also have some time to make progress on `union` semantics.

+After exploring [a "validity"-based model]({{ site.baseurl }}{% post_url 2017-08-11-types-as-contracts-evaluation %}) last year, I am going to be looking at an "alias"-based model this year.
+That's the kind of model @arielb1, @ubsan and others have been proposing, and I am going to build on top of their work and hopefully come up with something we can actually implement a checker for
+(staying true to the [vision I laid out previously]({{ site.baseurl }}{% post_url 2017-06-06-MIR-semantics %}) that we should have an executable operational semantics for MIR, including its [undefined behavior]({{ site.baseurl }}{% post_url 2017-07-14-undefined-behavior %})).
+Expect a blog post soon for what I mean by "validity"-based vs. "alias"-based, and for a first draft of such an "alias"-based model.
+
+Until then, stay tuned!
