Update calendar with "friendly events"

[samumantha]

Use workshops or community calendar: https://github.com/coderefinery/calendar/blob/main/calendars/workshops.yaml

• - [ ] https://scicomp.aalto.fi/training/scip/ttt4hpc-2024/
• https://ssl.eventilla.com/snakemake_hack
• ...

Check other calendar entries for syntax :)

How to do this in more sustainable way?

[tpfau]

• Update by adding the respective Pages from Other orgs.
• potentially link calendars.

This seems to be able to combine two ICS files, so that friendly events could be included without duplication:

a = ics.Calendar(open('out/community.ics').read())
b = ics.Calendar(urllib.request.urlopen('https://coderefinery.github.io/calendar/all.ics').read().decode())

c = ics.Calendar(events=a.events+b.events)
open('out.ics', 'w').write(c.serialize())

git-calendar could possibly be updated to do this natively (seems pretty easily: the the include would be changed to the processing of event list b above):
https://github.com/coderefinery/git-calendar/blob/main/git_calendar/yaml2ics.py#L148-L153

Other things

• git-calendar could use some love and make sure it's packaged and maybe even used without the current submodule method
• yaml2ics comes from another package (see the top). Update it based on upstream improvements. Maybe un-vendor it. Maybe contribute the new "include ics" thing upstream?
• Set yaml2ics to include .ics files based on the above (and maybe also be able to open .ics files with urlopen?)
• lots of testing! ICS parsing has been a bit fragile, I must say.

[rkdarst]

The above would rely on the other organizations having a .ics feed but that seems to be the minimal we can hope for(?)

I think I implemented this here: coderefinery/git-calendar#10

Should I just merge that PR?
Do I understand it correctly, that calendar will automatically pull the main branch from git-calendar and use that in the workflow, i.e. when this PR is merged, no further action on calendar (besides adding other calendars) is needed ?

I'll put down a list of pages for training here for now:
CSC - https://csc.fi/en/trainings/training-calendar/
NRIS/Sigma2 - https://www.sigma2.no/training-and-events
ENCCS - https://enccs.se/events (ICS at : https://enccs.se/events-at-enccs/list/?shortcode=5210815c&ical=1)
UPPMAX - https://www.uu.se/en/centre/uppmax/study/courses-and-workshops
PDC - https://www.pdc.kth.se/training (ICS available via https://www.pdc.kth.se/api/icalendar/export/2.78462?l=en_GB&c=all )

git-calendar now supports adding downloadable calendars (including those not as direct ics downloads, but as a download url).

Now needed:
Proper ics exports from Aalto, NRIS/Sigma2/Uppmax/csc

[samumantha]

Maybe we could just link these above pages from our calendar page on the website?
