This page aims to keep information public about Sage's infrastructure. Question mark means that the information is not confirmed, please edit if you know more... and note the date of your update so that current and stale information can be distinguished.

Please mark which services still need to find a new home, with the system requirements and the deadline.

Planned services (wishlist)

  • schilly: who wishes this and did define those purposes based on what discussion?
  • tmonteil: this is a wishlist, not something collectively decided. Note however that almost nothing in the current framework was collectively discussed either.

backup

stats

  • purpose: stop feeding google-analytics database
    • schilly: strong objection, we have a long time history stored there and it's far better than any other tools
    • tmonteil: i hope this long time history could be easily fetched in some open format, or does this mean that we locked ourselves there? (being locked would imply that this tool is among the worst)
    • tmonteil: better for who? for google and the NSA to which we currently provide all our visitors IPs? There is a serious privacy issue with such analytics saas tools.
  • public stats are here http://www.histats.com/viewstats/?SID=1579950&f=2

    • novoselt: horrific page - I thought such blinking adds are a thing of the past, had to close it before finding any data
    • tmonteil: note that free software alternative do exist

lists

  • purpose: do not depend on googlegroups (see what happened with googleID on ask and sagenb)
    • schilly strong objection: what has this to do with google id?
    • tmonteil: googleID is an example of a service that was stopped by google, with strong consequences on our side (some people not able to connect anymore (e.g. on ask.sagemath.org), or not able to retrieve their work (e.g. on sagenb.org)). What will happen when google will decide that googlegroups will be shut down? Would we be able to discuss with them about this issue?
