Why are we back to the "Vector" skin?

I personally preferred 'Timeless' (see and for reference, but unfortunately the hover menus broke with a recent update on this instance, leaving me totally clueless as to wtf this happened. It does not seem to be a widespread issue and replacing the files in question did not solve the problem either. ~Peter (talk) 18:13, 1 July 2020 (CEST)



This Wiki and its contents are going to be migrated sooner than later. Please keep contributing content nontheless. Depending on the choice of a new wiki software and whether a (semi-)automatic migration is possible, the new wiki will be hosted under, while this wiki will remain under until migration is complete.


The new wiki is going to be hosted under the domain.


Hosting: A move onto's server infrastructure is likely, but other options may be considered.


Mediawiki is great, but.. other software may be better and more versatile. We might stay on MediaWiki, but at this point, alternatives should be considered in order to move just once. Under active consideration are:

  • DokuWiki
  • XWiki
  • MDwiki (no longer in active development)
  • please feel free to add more options here!

Knowledge base "how to green a conference"

Collect valuable sources of knowledge and discuss it :)

  • one goal already reached in Leipzig: a sustainable caterer (improvements still needed)
  • a "completely green event" by Deutsche Bundesstiftung Umwelt:
  • a little bit offtopic but maybe worth a read:

  • we might need:

  • a co2-calculator for congress related transports/storage, travel, accomodation + and something to compare it to other events

  • still unsorted links:


    unsorted thoughts:

  • at 35c3 (partially already at 34c3) we had a local transportation ticket included and collectively financed :)
  • many things at congress are built with wood :)
  • we have an inhouse navigation tool and inhouse phone system (POC), reducing costs for international guests :)
  • congress helpers often sleep at hostels or collective housing projects :)
  • we have "congress everywhere" :)
  • we collectively re-use and repair old gadgets at congress - and we teach others how to do it (soldering!!) :)
  • our electronics gadgets are mainly made of plastic, have a short lifespan and use lots of power :(
  • is the energy source for heating and electricity at congress/camp/event sustainable?
  • -> (Messe Leipzig?!
    -> sustainable fairground with tents

  • could we ask a bike sharing company to deliver ~100 bikes to the CAMP? this might reduce individual transportation costs and reduce loading space and coordination efforts. if the bikes can be used "30/60 minutes for free" or locally used via an untracked codelock app, we might just pay the bike rental a general fee for delivery&service
