My system has a dark theme, which means my thunderbird has a dark theme too.

TIL - Rust crate lib and binaries are separate compile unit
May 6, 2020

Given a rust crate with three files: lib.rs main.rs common.rs When lib.rs and main.rs are compiled, they are each compiled in their own independant compile unit. This means that we have to put mod common inside each file. But the better approach is to put mod common inside lib.rs and do use my_crate_name::common inside main.rs or other binaries within the crate.

TIL - EGD Erlang library
April 23, 2020

I use elixir in a lot of project, but I am not very familiar with the erlang eco-system. My wife was taking an elixir course and she had to use the :egd library. It’s a very simple image library where you can create draw surfaces then on them you can draw line, ellipse, rectangle and text. While it is quite limited, it might come handy for simple uses. Doc: http://www1.erlang.org/doc/man/egd.html

Today, I start writing my TIL (Today I Learned) on this blog
April 23, 2020

Today I saw this repository https://github.com/jbranchaud/til/blob/master/README.md and I realized it would be very cool to start doing that. I often struggle on what to write on a regular basis, and I think going for “TIL” is nice way to share knowledges without having to write a full post.
