+Rust Cologne is a monthly meetup dealing with everything Rust.
+This Meetup we'll talk about common and lesser known pitfalls when writing async Code.
+
+_(The meetup will likely be held in German but we'll switch to English if needed.)_
+
+Dear Rustacean,
+
+you are hereby warmly invited to join the next Rust Cologne meetup. Whether you want to speed up your python code, write a web service, need interop with your C++-codebase, cross-compile for a microcontroller, write an emulator, … we've got you covered!
+
+We commonly open up with a brief summary of noteworthy changes in the Rust ecosystem. Be it updates to the language itself, public events, its impact on other projects and languages, …
+
+"If it compiles, it works" is a common feeling when writing Rust code. A strict type-system, proper linting and helpful compiler messages prevent lots of problems common in other languages. "The thrill has gone …" is a common feeling when writing `async` Rust code.
+
+As more and more crates evolved around that language feature, so did the challenges: surprising deadlocks, lost results, increased complexity, lifetime-issues, data loss, …
+
+In this meetup we talk about how `async` is _different_ from ordinary Rust and how to tackle at least some of the challenges it brought to the language.
+
+As usual, the remaining time is about whatever _you_ want to talk about!
+
+Always wanted to know why Rust is harder to learn than other popular languages or why it lacks a certain feature? When is it appropriate to rewrite a project in Rust? Is the compiler really that slow and are the binaries really that big? Do all those safety guarantees have an impact on the performance? Fetch a drink and let's find out.
+
+**[You can register here](https://www.meetup.com/rustcologne/events/312789818/)**.
+
+See you soon!
+
+Yours,
+Florian and Kai
