Artcyclopedia hotlinking Commons thumbnails
by Brianna Laugher 13 Jun '06

13 Jun '06

Hello, [[w:Wikipedia:Mirrors and forks]] seemed to suggest I should report this here. Artcyclopedia appears to be hotlinking our image thumbnails, although they link to the Commons image description page (see eg. http://www.artcyclopedia.com/commons/leonardo-da-vinci.html ). I'm not sure what if anything should be done. Thanks, [en.{wp,wb}|commons|meta]:User:pfctdayelise

Search status
by Brion Vibber 13 Jun '06

13 Jun '06

Last week I added some statistics reporting to our search daemon. It keeps track of a 1-minute rolling average of the rate of handled requests, discarded requests, the time it takes to service a request, and the number of simultaneously active threads. This info is reported to Ganglia, and can be watched at eg: http://ganglia.wikimedia.org/large/?m=search_rate&r=hour&s=descending&c=Sea… http://ganglia.wikimedia.org/large/?m=search_time&r=hour&s=descending&c=Sea… With a better idea of the actual performance of the system, we've been able to put some work into optimizing the system a little better. First, several more old Apache boxes have been commandeered, increasing the search cluster from 3 to 8 machines. Second, Tim has switched the load balancing from simple round-robin plus failover to a more flexible and cleaner system using perlbal. We found that the boxes with 3+ gigabytes of RAM performed significantly better than the boxes with only 1 gig, probably because they could not dedicate as much memory to caching the on-disk index files. As of today, the cluster has been split into two groups, each separately managed by perlbal. The four 3+-gigabyte machines handle en.wikipedia.org and de.wikipedia.org, our two biggest and most active wikis, and the 1-gigabyte machines handle everything else. We'll know better during peak hours tomorrow, but so far it looks pretty good; reported dropped connections have nearly vanished, and average service times are below 50ms for all boxen. Future work: River has done some work on fancying up the search for Wikia, but we haven't yet gotten a clear agreement on whether or not the company is willing to open-source it. If they do do this soon, we may adopt Wikia's code. If not, we'll continue working on the base we've got to spiffy it up. The first order of business is doing another round of comparisons on the base VM: currently we're running on Mono, which was chosen originally for the combination of being 1) open source, 2) reasonably performant, 3) not leaking memory. GCJ was a touch faster, but leaked memory. Sun's JVM didn't leak memory, but isn't quite open-source. Somewhere along the line, though, the Mono version sprung a memory leak and we have to restart the daemon regularly to keep it from dying. I'm uncertain whether this is in our code, in the Lucene port, or in Mono itself. I'll want to check with a more current update to the C# Lucene port, and update the Java code to test against current versions of GCJ/Classpath and Sun's JVM, now that Lucene 2.0 is available. Another important improvement we could make is better indexing updates: we should at least be able to add new pages to the index in close to real time, even if full rebuilds are still more intermittent. And if it's ready for another release, I may check out the Sphinx search engine as well. It claims better speed and result ordering than Lucene, but when I was first testing it out it was too much in flux with a lot of new stuff going into the development version. -- brion vibber (brion @ pobox.com)

Math dir is empty
by Farshad Bashir 12 Jun '06

12 Jun '06

Hallo all, I have Mediawiki now for 1 year and everything worked fine. I upgraded my OS to Fedora Core 4 (from 2) and I upgraded my Mediawiki version to 1.6.7. I have set $whUseTex to true and then installed imagemagick, latex, dvips, gs, and convert, TeTex, Ghostscript and AMS fonts. I have also compiled texvc. I next loaded one of his pages and get in red text: Can't write to or create math output directory) I can see the PNG-file in the ../images/tmp/ dir, but nothing in math dir... I thing it has to do something with the new hierarchy of ../images/math/ dir, but I don't know. images/math exist. PHP is not runnig under "safe mode". Please help me, beceause I become crayzy, I am now working days on this issue. Thanks and kind regards, Farshad Bashir

I've searched the archives for the past several months, and cannot find the status of this project, other than a busy fellow saying that it was the top priority in February. Anybody know?

CALL FOR PARTICIPATION WIKISYM 2006: THE 2006 INTERNATIONAL SYMPOSIUM ON WIKIS August 21-23, 2006, Odense, Denmark CO-LOCATED WITH ACM HYPERTEXT 2006 See http://www.wikisym.org/ws2006 Archival - Peer Reviewed - ACM Sponsored EARLY REGISTRATION DEADLINE APPROACHING: June 19, 2006 GENERAL INFORMATION This year's Wiki Symposium brings together wiki researchers and practitioners in the historic and beautiful city of Odense, Denmark, on August 21-23, 2006. Participants will present, discuss, and move forward the latest advances in wiki contents, sociology, and technology. The symposium program offers invited talks by Angela Beesley ("How and Why Wikipedia Works"), Doug Engelbart and Eugene E. Kim ("The Augmented Wiki"), Mark Bernstein ("Intimate Information") and Ward Cunningham ("Design Principles of Wikis"). The research paper track presents and discusses breaking wiki research, the panels let you listen to and contribute to topics like "Wikis in Education" and "The Future of Wikis", and the workshops let you get active and contribute to on-going research and practitioner work with your peers. (Many workshops accept walk-ins, so it is not too late!) What's more, for the first time, we will have an on-going openspace track (to replace BOFs) so you can get active and involved in an organized fashion on any wiki topic you like. We believe this is how to get the most out of your experience at WikiSym 2006! And, of course, if you can't wait, please join our conversation on wiki research and practice on the symposium wiki at http://ws2006.wikisym.org PROGRAM OVERVIEW See http://www.wikisym.org/ws2006/program.html Keynotes and invited talks: * Angela Beesley: How and Why Wikipedia Works * Doug Engelbart and Eugene E. Kim: The Augmented Wiki * Mark Bernstein: Intimate Information * Ward Cunningham: Design Principles of Wiki Panels on: * Wikis in Education * The Future of Wikis Research papers and practitioner reports on: * wiki technology * wiki sociology and philosophy * wiki uses, for example, in software, education, and politics and many more, see http://www.wikisym.org/ws2006/program.html#Papers Workshops on: * wikis in education * wikipedia research * wiki markup standards * wikis and the semantic web And, of course: Demos! We have pre-set demos, but please feel free to bring your own notebook! We will provide space for you to demo on-the-spot in our Monday night demo session, a favorite from WikiSym 2005.
