     * tmonteil: backup of the data of the services we maintain: ask, trac, git, wiki,... according to [https://groups.google.com/forum/#!msg/sage-devel/ed_ya-d-k_E/5csVA6wsCwAJ this] [http://comments.gmane.org/gmane.comp.mathematics.sage.devel/84894 post] there is currently no regular backup at all for those services (except ask, that benefits for a semi-automatic backup system), this is why i proposed to have a server dedicated to that, located in a different place than the other services.
     * we got a VM at [[https://www.math.u-psud.fr/|Orsay math department]] with 1TB of disk, we are currently setting it up, and use it for more and more services.
Line 142: Line 165:
    * 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.
Line 144: Line 169:
    * tmonteil: note that free software alternative do exist
Line 148: Line 174:
     * 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?

  • 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.

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)).
