What will happen when google will decide that googlegroups will be shut down? Would we be able to discuss with them about this issue? |

- hosted at:
www.uni-frankfurt.de (Frankfurt, Germany)
Universidad Autónoma de Madrid (Madrid, Spain)
- Google Compute Engine (Council Bluffs, Iowa, USA)
- technology used: production installation requires a dedicated server (either physical or virtual)
- resources needed:
- RAM: 32GB recommended for smooth operation, 16GB may become enough in the future
- CPU: the more the better for handling spikes in load and allowing parallel interacts, but any will do if necessary
- DISK: must have BTRFS at least for /var/lib/lxc, SSD is preferable, 100GB should be sufficient for the foreseeable future
- admin: novoselt
- contact: novoselt
available urls: http://aleph.sagemath.org, https://sagecell.sagemath.org

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
- purpose: backup between remote hosts, local backups can be destroyed
- schilly: backup of what?
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 Orsay math department with 1TB of disk, we are currently setting it up, and use it for more and more services.
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?
