We are students of ETH who help you with linux
at our events and in our office. For free!

Because we love Open Source and Free Software
and want to help you to get started (here's why).

This semester, we organize REPLICATE: Events
to help you use and produce Free and Open
Science, Hardware, Software and File Formats.

PDF = PestesDateiFormat

Fri 07.05.2021 17:15 - 18:00 | Online | register

The course will be broadcast online

Take a deeper look into how a PDF file is structured, and learn about the pro / cons of the file format. As part of this talk, we will look at the PDF and TTF specification and a (unfinished) PDF compiler (=a program that creates PDFs). At the end of this talk, you can create a minimal PDF from scratch in a text editor.


Wed 12.05.2021 18:00 - 20:00 | Offline if possible

The weather is getting better, Corona is getting (somewhat) weaker; it is time for a Stammtisch!

We meet in a casual atmosphere, drink a (non-alcoholic?) beer and have a chat about technical/educational/societal trends... Come join us!
We can also help with some Linux problem, just bring your laptop.

Use the contact form, or write directly to info (at), so we can include you in the invitation.

We are both graduates and undergraduates from different fields of study. Together, we provide courses and other educational material around Open Source and Free Software. This lowers the entry barrier for others, and improves our own understanding.
