Remote usage of Aalto's workstations

Check the page and possibilities, if you find it interesting:

mfavdi.aalto.fi

https://www.aalto.fi/fi/palvelut/it-palvelut-opiskelijoille  (FI) ->Etätyö - VPN ja VDI

https://www.aalto.fi/en/it-for-students (ENG) -> Remote Work

If this works / (does not) ->let us know!

The main idea for the course realization is that the "contact teaching" will be in TEAMS:

- lectures

- simulations

- lectures (Tuesdays at 16.15 o'clock) -> Join Microsoft Teams Meeting

- simulation sessions (6 official sessions, starting on 7.10.2020, on Wednesdays at 16.15. o'clock)

"See you" on Tuesday!

General idea for this Systems course is that we have the possibility for remote learning by using TEAMS or corresponding platform.

However, we will follow the instructions given by the university!
