Hi,
I've created a brand new sagenb.org VMware virtual machine. It's
state is the same as the sagenb.org
virtual when it is was fork bombed.
The main difference is that now:
1. It is running in a VMware virtual machine on my desktop. The
virtual machine
has 2GB RAM, 10GB swap, and 4 2.6Ghz Xeon cores. I don't know if this
will hold up to the load at all -- we'll see.
2. I made a snapshot, so if the server gets hosed, it's a trivial
mouse click to fix it.
3. It uses http instead of https, so nobody will get those "invalid
security certificate"
warnings. This means, of course, that people can sniff
passwords -- I say, who
cares, given that anybody can pretty easily see the data of any
other user and
this is just a free public resource for evaluation purposes.
4. The virtual machine itself is currently on an external USB disk,
so disk IO may
be slow. I may have to move some data around to improve this.
5. I set the sage server to save state to disk only *once* per day,
instead of the
default of every 6 minutes. This is the operation that still
made the server
feel slow every few minutes, and is now much less necessary, since all
worksheets are always stored on disk as files anyways.
Please try it out. Let me know if there is any particular free/open
source software
that you want me to install, which I forgot to install. (E.g.,
something for tex or whatever.)
Harald: Definitely feel free to add a link to this to the sagemath.org website.
Once this particular vmware image gets some usage, it could easily be adapted
into something that I redistribute. It's a 64-bit Ubuntu linux
install actually.
