Sorry for the downtime, but given the choice between sagemath.org DOSed by the wiki or no wiki the choice was clear. Since the wiki is running now, maybe you could update this message? The issue is still not fixed, so I would wait until we know better. But the way it look right now the wiki will stay up. Also, assuming that the above situation were the case, it would be best to use ulimit to run the wiki, so that it would get auto-killed if it exceeded say 8GB RAM, then just restart it (that would be an easy few-lines script). I did something like that, but limited it to about 1GB. And it has stayed up since without restarts. Something strange is going on here, i.e. his happened twice in a day after many weeks of working fine after the last time we had trouble. I got some thoughts what is wrong, but I will share those later. -- William Cheers, Michael --~--~-~--~~~---~--~~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

Just in case: What do you have in mind? Cheers, Michael All the same, MoinMoin scales *horribly*. Sure, no secret there. But we are getting a couple thousand hits a day on the wiki on a busy day, so scalability is not really a problem. Once we are closer to achieving world domination I guess we would need to reevaluate our options :) I didn't have a specific replacement in mind, though over at Fedora we recently transitioned from MoinMoin to Mediawiki specifically because MoinMoin was becoming too slow. If you can get MoinMoin to use a database it might not be so bad but last I heard it only supports flat files for storage. Sure, but the fact that moinmoin just works without the need for any configuration of a sql database is a killer feature since it might not be a problem for some people on this list to set up mysql and so on properly, but many, many Sage users will not even know what a sql db is and not even care enough to attempt to find out what it is. They just want something that works and so far for 100% of the Sage users it seems that moinmoin scales well enough :). One example: It has emerged from the AMS 2009 meeting that the installation of the VMWare player is a hurdle many people will not get over, so that is a barrier for the adoption of Sage. While you and me are probably snickering a little since this is trivial most people want to use software, not learn how to install it and so on. Not that you ever claimed anything like this, but it is kind of like gear heads talking about cars: If I get this carburator/shocks/ $INSERT_CAR_PART installed it would be so much better to drive $FOO/ get much better fuel efficiency (note that I don't have any clue about cars), but the vast majority of people use their car to get from point A to B and if the warning lights go on they go to a garage to make somebody else deal with it. But if they had to do difficult tasks to even get a particular brand of car started many of those people would just chose another brand. With Sage we have to get to the same utility level as this and the VMWare image is a problem now, just like using 7zip instead of zip to compress the VMWare image proved a major issue with non-technical users in the past. So even though the zip archive was roughly 60% larger than the 7zip one we switched back to zip. And back then I thought that this was a bad move and we should not cater to users who cannot read the simple README.txt pointing out where to download 7zip and so on, but now I see the error of my ways :) Regards, -- Conrad Cheers, Michael --~--~-~--~~~---~--~~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

It would never occur to me to do that and I always found it a bit strange that we ship a wiki software. So, are there endusers of the wiki bundled with Sage?

Even though now I think that setting things up independently of Sage might be less work in the long term since we can more easily customize things. On the other hand I don't want to do the work, so I am not seeing this change any time soon. -- Conrad Cheers, Michael --~--~-~--~~~---~--~~ To post to this group, send email to sage-devel@googlegroups.com To unsubscribe from this group, send email to sage-devel-unsubscr...@googlegroups.com For more options, visit this group at http://groups.google.com/group/sage-devel URLs: http://www.sagemath.org -~--~~~~--~~--~--~---

Martin I asked the same question a while back and William told me that there are actually people who installed Sage just for the moinmoin wiki came with it since it just worked. Our version also ships with jsmath already properly configured, so this seems to be a big plus as well. It is certainly not very well advertised that we ship a wiki with Sage and given its size I don't think the benefit of removing it will outweigh its small size.
