On this particular project, if my calculations are correct. Actually one!

but in reality a lot of people worked to made it possible. This uses only Free Open Source Software.
So a lot of people put their brains here.
we use: linux, debian, python, django, postgres, skeleton, sqlite, and many other software that so many people put their time on it.
So thank you all the people who works on FOSS. Thank you!

Thanks Ada Lovelace in the first place. I would have no job if wasn't her.
