+
+The [rust programming language](https://www.rust-lang.org/) seeks to solve several of the problems that have plagued earlier languages for systems development.
+
+Rust has started to become a [very popular choice](https://www.rust-lang.org/production/users) for performance critical projects. It is used inside the Firefox browser, at Dropbox, at ByteDance, and is also being [considered to be used inside the Linux kernel](https://arstechnica.com/gadgets/2021/03/linus-torvalds-weighs-in-on-rust-language-in-the-linux-kernel/) alongside C.
+
+With it's language features rust has managed to bring with it several guaranties, such as the nonexistence of data-races and dangling pointers, while also moving typical runtime errors into the domain of compilation errors. 
+
+
+If you want to understand how rust can give these guarantees or if you just want some insight into a very interesting language then join our introductory lecture to rust!

+Join us to code on the advent calendar Advent of Code, drink julmust and eat gingerbread cookies!
+
+We will demo some problems from last year, and then help you out solving the first problems from this year!
+
+### About Advent of code
+
+The Advent calendar Advent of Code starts already the _1st of December 06:00 CET_.
+
+Until the 25th of December a **new programming puzzle** is released each day at: [https://adventofcode.com/](https://adventofcode.com/)
+
+Code@LTH has a private leaderboard, where you can compete against other Code@LTH members in solving the puzzles as fast as possible (or perhaps the main competition is about how early you manage to get out of bed). 
+
+Join our leaderboard with the code: `107707-7795f557` at [https://adventofcode.com/2021/leaderboard/private](https://adventofcode.com/2021/leaderboard/private).
