Furthermore, since Tachikoma.jl works entirely on Julia without relying on external servers or other things, it is so much easier to integrate the UI with the back end. It was very straightforward to build this app.

> Hi! Some of you know that one of our biggest accomplishments here at the Brazilian National Institute for Space Research (INPE) was to build a validated satellite simulator that is being used in all phases of the attitude and orbit control subsystem (AOCS) development. I always knew that one day I will need a proper TUI to allow me to debug the algorithms more easily than wait for execution and analyze the results. Hence, 7 (SEVEN!) years ago, I started to code TextUserInterfaces.jl, which is …
