[OpenGuides-Dev] OG performance
by Paul Makepeace 20 Jun '07

20 Jun '07

Hi, I don't follow OG development but as host operator a few things are coming up. The machine's load is gradually climbing over time and some of that is OG. Despite a relatively low hit rate on OG it is consuming quite a bit of resource. If OG started taking off it would take the machine down. First up: index.cgi requires 0.35s to perform a `perl -c` syntax check. Any thoughts on putting OG on a mod_perl server? I have mod_perl running here of course and we'd need to coordinate some apache.conf stuff. Second: the supersearch.cgi gulps down CPU, often for seconds at a time. It is a frequent resident of `top` output. This isn't really acceptable. I'm going to request this feature be turned off unless an effective optimisation plan or some other way to reduce its impact here is constructed pretty soon. Sorry about this but it's encroaching on others. Third: I wonder if there's some way to instruct robots not to spider parts of your wiki. This ought to speak for itself: $ grep crawl /var/log/apache/london.openguides.org-access.log | grep 'action=edit' | wc -l 8242 $ Finally: I posted about a DoS and was wondering what the status of a solution was. http://openguides.org/mail/openguides-dev/2004-October/000542.html Cheers, Paul (any overbearing tone unintentional ;-) -- Paul Makepeace .............................. http://paulm.com/inchoate/ "If my elbow was straight, then I'll show oyu mine!" -- http://paulm.com/toys/surrealism/

paralanguage Guides
by Jo Walsh 05 Feb '07

05 Feb '07

dear all, i've been visiting Berlin a lot and would like to start a Guide so i can write about the funny and useful places that i find or am shown. but i don't speak any German and i want to keep it that way - it's an awful language. ( http://www.crossmyt.com/hc/linghebr/awfgrmlg.html ) i thought about asking for best practise / prior art on multilingual Guides. the thing is i am not worried about having translations, and i would sort of rather have any language that people feel like writing in, squashed onto one page, than separate stuff out, in a way which might make different language communities feel unwelcome or lapse into local minima. i could do quite a lot with silly icons, and categories can have names in any language, that's fine, and i'm not worried about knowing what language category names are in - people will understand or not understand - and one day we can do some magic with http://omegawiki.org if we like. how is the OG collective hosting situation? it would rock my world if i could park this somewhere i would not be subsequently responsible for breaking and upgrading ;) love, jo

Scripting for the Semantic Web Workshop (and Scripting Challenge) - Call for Papers
by Tom Heath 18 Jan '07

18 Jan '07

Hey folks, Some of you who are more into Semantic Web, Microformats, or Mashups might be interested in this workshop. Note that for those people not into writing academic papers, there is also a Scripting Challenge (with prize) that doesn't require attendance at the workshop and only requires a short paper for submission. Please pass on to anyone you think may be interested. Cheers :) Tom. ------------------------------------------------------- CALL FOR PAPERS ------------------------------------------------------- 3rd Workshop on Scripting for the Semantic Web http://www.semanticscripting.org/SFSW2007/ co-located with 4th European Semantic Web Conference June 6, 2007, Innsbruck, Austria ------------------------------------------------------- Scripting languages such as PHP, JavaScript, Ruby, Python, Perl, JSP and ActionScript are playing a central role in current development towards flexible, lightweight web applications following the AJAX and REST design paradigms. These languages are the tools of a generation of web programmers who use them to quickly create server and client-side web applications. Many deployed Semantic Web applications from the FOAF, RSS/ATOM, blog and wiki communities, as well as many innovative mashups from the Web 2.0 and Open Data movements are using scripting languages and it is likely that the process of RDF-izing existing database-backed websites, wikis, weblogs and CMS will largely rely on scripting languages. The workshop aims to bring together developers of the RDF base infrastructure for scripting languages with practitioners building applications using these languages. Last years Scripting for the Semantic Web workshop in Budva, Montenegro focused on giving an overview about the support for Semantic Web technologies within scripting languages. The special focus of this year's workshop is the role of scripting languages in the process of populating the Web with linked RDF data as well as to showcase innovative scripting applications that consume RDF data from the Web. The second focus of the workshop is to show how Web 2.0 applications and mashups can benefit from Semantic Web technologies. The workshop will include a scripting challenge (conducted for the 2nd time) which will award a prize to the most innovative scripting application. TOPICS OF INTEREST Topics of interest include, but are not limited to: Infrastructure * Semantic Web frameworks and APIs for scripting languages * RDF repositories and query languages implemented using scripting languages * Reasoning engines implemented using scripting languages * Semantic Web publishing and data syndication frameworks * Approaches to crawling Web data and querying distributed data on the Web Applications * Semantic Web applications using scripting languages * Approaches to RDF-izing existing applications, such as RDFa and GRDDL * Mashups that provide RDF views on Web 2.0 data sources such as Google, Yahoo, Amazon or eBay * Wikis, weblogs and data syndication systems using RDF * RDF/OWL editors and authoring environments * Scripting applications for visualizing Web data. * Semantic Web Mining and Social Network Analysis * Mashups that demonstrate the novel capabilities of Semantic Web technologies Conceptual * Rapid development techniques for the Semantic Web * Employment of scripting language characteristics for Semantic Web development * Scalability and benchmarks of Semantic Web scripting applications Scripting Challenge The workshop includes a scripting challenge which will award a prize (an Apple iPod Video or alternatively Euro 200 cash) to the most innovative small scripting application or mashup. The application must be implemented using a scripting language and Semantic Web technologies. It should access, visualize or combine information from different sources in new unforeseen ways. Authors of Scripting Challenge submissions are not required to attend the workshop personally. Please refer to Tom Heath for further information about the Scripting Challenge. IMPORTANT DATES Submission deadline: March 30, 2007 Notication of acceptance: April 28, 2007 Camera-ready paper submission: May 7, 2007 Workshop date: June 6, 2007 WORKSHOP CHAIRS * Chris Bizer, Freie Universität Berlin, Germany * Sören Auer, Universität Leipzig, Germany and University of Pennsylvania, USA * Gunnar Aastrand Grimnes, DFKI Knowledge Management Lab, Germany * Tom Heath, Knowledge Media Institute (KMi), United Kingdom SUBMISSIONS We seek three kinds of submissions: * Full papers - should not exceed ten pages in length. * Short papers - are expected up to 5 pages. * Scripting Challenge Submissions - 2 page description of the application, ideally accompanied with the source code and a link to an online demo. PROGRAM COMMITTEE * David Aumüller, Universität Leipzig, Germany * Danny Ayers, Independent Author, Italy * Dave Beckett, Yahoo!, USA * Uldis Bojars, DERI, Ireland * Dan Brickley, Semantic Web Vapourware, UK * Richard Cyganiak, Freie Universität Berlin, Germany * Stefan Decker, DERI, Ireland * Leigh Dodds, Ingenta, UK * Edd Dumbill, Useful Information Company, UK * Frank Fuchs-Kittowski, Frauenhofer Gesellschaft - ISST, Germany * Daniel Krech, University of Maryland, USA * Peter Mika, Vrije Universiteit Amsterdam, The Netherlands * Libby Miller, @Semantics, UK * Benjamin Nowack, appmosphere web applications, Germany * Alberto Reggiori, @Semantics, UK * Sebastian Schaffert, salzburg research, Austria * Vlad Tanasescu, KMi, The Open University, UK * Denny Vrandecic, AIFB, Universität Karlsruhe, Germany * Gregory Williams, University of Maryland, USA FURTHER INFORMATION Updated information about the workshop is found on the workshop website http://www.semanticscripting.org/SFSW2007/ For further information, please send email to sfsw(a)semanticscripting.org

Indeed. However loads of ours are blank, or too short to make really good description metatag content. Something like: If the page summary is less than X chars long, then making it up to 150 chars using page content and with a ... at the end to signify truncation" would be a bonus I'm sure. Cheers. Tom.

Thanks for the suggestions. I think we should, where possible, raise trac tickets and enhance svn with changes, so everyone will benefit.

However, if someone could think of a generalised way of doing it, we could ship a suitable navbar template.

What can we do for Super Happy Google Powers? Better titles certainly made a difference for London's ranking. Better URLs would, too - and I've just noticed this little trick they're using over at BITE: http://www.beerintheevening.com/pubs/s/15/155/Montagu_Pyke/Charing_Cross_Ro… Strip off the last bit of the URL and you'll see the link still works, so it's obviously just extra search-engine-enticement, akin to what they do at Amazon: http://www.amazon.com/Death-Life-Great-American-Cities/dp/067974195X/ Ideas anyone? -- Earle Martin http://downlode.org/ http://purl.org/net/earlemartin/
