Packaging for Linux

arch-linux package

Fedora package

RPM package

Ubuntu PPA

rsync.sagemath.org

  • purpose: the seed for mirrors, see MirrorNetwork for more details

  • hosted at: UW
  • technology used: rsync
  • resources needed:
    • CPU 1 core
    • RAM 2-3 gb (mostly for caching when calculating hashes)
    • DISK enough for all sage files (50+ GB)

  • hosted at:
    • Goethe-Universität (Frankfurt, Germany)

  • 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

Planned services (wishlist)

schilly: who wishes this and did define those purposes based on what discussion?

backup

  • purpose: backup between remote hosts, local backups can be destroyed
    • schilly: backup of what?

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
  • 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

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?
