In the past months we've focused on making teach-rs more technically accessible. We decided we went a bit "engineering-heavy" with the technical setup of teach-rs (e.g. first run a tool called modmod to specialize the material, then deploy it--and this required some familiarity with the technical details), and we identified this as a potential hurdle in allowing the use of teach-rs in academia.
We flattened this structure in #149. So there is now just "the material". The logic here is also that in university, it's quite common to just select exercises from a book, and students can still benefit from browsing around in a "what else is there" mindset.
As side-benefit, we also discovered we had some material that was already in the repo but not publically visible on teach-rs.trifectatech.org, so the publically available teaching material expanded! :-)
It would be great to have some input on what focus we should have going forward. Make the material even easier to self-host? Are people looking for slides in LaTeX+beamer? Do you want to see new material on particular topics?
