Hello everyone,

I created a [repository](https://github.com/pdeffebach/AdventofCode.jl) on Github for [Advent of Code 2019](https://github.com/pdeffebach/AdventofCode.jl).

I solved the Day One puzzle today. However being in grad school, so I might not have time to solve every problem myself. It would be great if other people could contribute to this repository throughout the month!

Feel free to fork it and contribute your own more efficient or robust solutions.

Best,

Peter

Advent of Code always manages to shake up my routine, but I think I’ve overengineered the Intcode interpreter…

Somebody posted an article in Japanese about my package [Grassmann.jl](https://github.com/chakravala/Grassmann.jl) for Advent 2019

> **[\[Julia\] 外積代数ことはじめ〜 Grassmannパッケージ - Qiita](https://qiita.com/tenfu2tea/items/42e8c28fbe79fa39a38c)**

here is an english translation: [[Julia] 外積代数ことはじめ〜 Grassmannパッケージ #Julia - Qiita](https://translate.google.com/translate?hl=&sl=ja&tl=en&u=https%3A%2F%2Fqiita.com%2Ftenfu2tea%2Fitems%2F42e8c28fbe79fa39a38c&sandbox=1)  
今年のプレゼントは、Grassmann.jl パッケージです。これを用いて、Juliaを外積代数の電卓にしましょう。外積代数を用いると、多次元空間の量を首尾よく記述できます。

> This is the 10th day of Julia Advent Calendar 2019 .
> 
> This year’s gift is the Grassmann.jl package. Use this to make Julia an outer product algebra calculator. Using outer product algebra, you can successfully describe the amount of multidimensional space.

If somebody is up for a challenge, they can translate this article and contribute it to the docs as tutorial.
