This site is remote loading the Italian wikipedia: http://wikipedia.sapere.alice.it/wikipedia/wiki/Special:RecentChanges and adding a topbar (it's not an html frame). Incidentally, it's a subsite of a major Italian telecom company... do they have some kind of agreement? Ciao, Alfio

7zip dump format
by Stian Haklev 03 Mar '07

03 Mar '07

Dear all, thank you for your feedback. I have been sick for a few days, but I'm back :) And I just released 0.22 of the software, which is a bit more robust - the 7zip issue is still unresolved though. (http://houshuang.org/blog/wikipedia-offline-server). 7Zip blocksize: Initially I was looking into whether this was the problem (suggestion from Igor Pavlov, the developer), but I think we can conclude that this is not the problem, since the block size is already quite small. Also, this doesn't make sense since the time it takes to uncompress files is proportional to the number of files - on my old computer, 15 seconds for Indonesian (60MB), 30 seconds for Norwegian (120MB), 150 seconds for Chinese (250MB), too long for French (500MB)! Whereas I tried to zip a GB of 1MB pictures, and unzipping just one of them, even if it was in the 700th MB, was snappy. I tried looking at the 7zip code again, but it's still too complicated, with too many files involved, for me to understand anything. However, it makes all the sense in the world to me that building up an index beforehand of file names and blocks (possibly using 7za l -slt), and then feeding the block number to the 7z extracter, and having it jump directly there. (or if it needs more specific information, making a lister that outputs that information, and then feeding that). Platonides: I don't know if having 7z run constantly is a good idea. While I am not wedded to Ruby, it makes it very easy to do regexps, add small features, and the built-in webserver is very nice (includes threading)! However, if you got this to work, I'd love it. Personally I think it's all about building an index. By putting 2 million filenames + block locations into for example an indexed mysqlite3 database, it should be able to extract one of them in milliseconds. However, what 7zip does does not seem optimized - what I saw was a simple for-next loop of all the filenames (and this is being done by looping the data on disk, not on a model in memory)... If you had any chance to have a look at this and try it out, I would be eternally grateful! Try downloading a bigger dump file (Chinese/Norwegian whatever), and you should very clearly see the speed hit. Try manually inserting what information it needs (for example block location) for a specific file, and see if it then extracts that file very fast - if yes, we can make it a cmd-line argument. Thanks a lot Stian

" I am not definitively an expert on this field, so take my opinion for just an opinion. Moreover I have found difficult to understand what it is written in the Wikipedia article. For instance after saying what was quote above (from hence one can conclude that it is a workflow), it is stated that "it is not a data flow" > > > > Thus it would seem that BPMN is already an image file of some kind. Following the external links on the article, I arrived to some pages that let me think that BPMN only give the semantic, but not the graphic format, and for the graphic format you should better refer to BPEL4WS (Business Process Execution Language for Web Services) and web page http://content.europe.visual-paradigm.com/media/documents/bpva10BPMNSpec/ht… told you to refer to http://www-106.ibm.com/developerworks/webservices/library/ws-bpel/ I have just give a quick gaze to that and I think that it define an XML format for the content/image. So if you have a file in that format the problem is to find an handler for that, in the same way you need an handler to handle SVG file. Onother way would be to find a way to convert into SVG format (which sounds to be a better choice than JPG for such type of image). (or if you want a bitmapped format and not a vector format, PNG format should be better than JPG, anyway) > You could try to use Graph::Easy for it: > http://bloodgate.com/perl/graph/ > http://bloodgate.com/wiki/Graph If what I have understood is correct, BPMN has more items than a flowchart. And the differences means not only more semantic declarations, but also more graphics item types. So I wonder if Graph has already all this graphics types required for that format. Even if, you would have to convert from the BPMN or BPEL4WS to Graph format to have it to work for such a format. But, before trying to get a way to do the thing technically, it should be clear what you are looking for. Have you already a file in that format (in the same way if you had an image in svg or jpg format, in a separate file) and you want a way to have it displayed (as an image and as a thumbnail) or do you want a way to insert the code in the wiki page, to generate an image (in a way similar, for example, to the Graph extension or the EasyTimeline one)? All the best AnyFile

BPMN 2 JPG convertor
by Paul van Erk 03 Mar '07

03 Mar '07

Hi guys, I was wondering if there is a BPMN (Business Process Modelling Notation) to Image convertor. So a user can upload an BPMN file, which is translated to a thumnail image which can be shown on the page (as can be done with normal images). I looked on the extension page, but I could find any. Could someone help me out? Thanks, With regards, Paul van Erk

Table editing
by Jim Hu 02 Mar '07

02 Mar '07

I've been working on making a set of extensions to make a table editing helper, which I'm tentatively calling TableEdit. The help page for the prototype is at: http://colimod.org/colipedia/index.php/Special:TableEdit ...with screen captures! The basic idea is that you can put <newTableEdit/> in your markup, and an extension will replace it on save with a link to a special page that can create the table by adding and deleting columns and rows. These are stored in an external mysql db with two tables. One keeps track of the tables in each page and the other keeps track of the content of each row. The row data is just a string of values delimited by '||' so it can be dropped right into the table markup. In the prototype, you can put a list of column headings between <newTableEdit>list</newTableEdit>, or you can specify a location for a list of column headings in a Template page. Individual rows can be editable by all or only by the creator and admins. This doesn't stop editing in the page itself unless you combine it with ProtectSection or some other protection mechanism. What I don't have working yet is: - Sorting - Inserting between existing rows and columns - Parsing the data back out of the wiki text. and as usual, the code could probably be cleaned up a lot. I'll try to post it to mediawiki as experimental this weekend, but I wanted people to see the doc page. Jim p.s. The wiki it's on doesn't allow anonymous registration or editing, so you won't be able to test drive it in place. ===================================== Jim Hu Associate Professor Dept. of Biochemistry and Biophysics 2128 TAMU Texas A&M Univ.

MediaWiki 1.9.3 wgLogo renders improperly
by Jeff V. Merkey 02 Mar '07

02 Mar '07

Please check and try to create an account on one of the two sites setup with 1.9.3 http://chr.wikigadugi.org http://en.wikigadugi.org Even though $wgLogo is setup correctly, the images fail to render on the default page with no user logged in. When you switch to a login panel or some other panel other than main display, the images then show up properly. They disappear completely when either logged out or when sitting on a main page for editing. Jeff

Wikix Image Detection in enwiki dumps
by Jeffrey V. Merkey 01 Mar '07

01 Mar '07

I have integrated the wikix program that extracts image files and analyzes image template usage in the enwiki dumps into the AI engine I use for machine translation projects. I use wikix to sync up with the Wikipedia Image repository. It has yielded some useful results as a side affect which may be useful for the Wikipedia community on the English Wikipedia. During analysis of the last dumps posted as enwiki-20070206, the program identified all tag usages in templates for image tagging in use on the English Wikipedia as well as all suspect image files which may be trojans, viruses, and other types of content which has been uploaded as images to the site. The image files and data are grouped into the following output logs from the English Wikipedia. Not all the files are trojans and some of them are probably ok , but a some may not be, particularly files named "spoof" and MS word files which can contain VB5 virus code if downloaded from Wikipedia. At any rate, the list of files and the articles which they link to are provided and it may be useful for someone to review these files since they appear to be file types which can harbor viruses and trojans. They are files I will not be hosting or pulling into Wikigadugi since they may contain malicious code. images.log - all image files referenced in the last enwiki dumps reject.log - all suspect files which may be viruses or trojans listed by article title which link to the image files fragment.log - all templates and image tags used in templates which alias to the Image: directive as some point through the website logic and the first article title in which they appear. (this is interesting to see how many tags people create in templates to map to Image:) These logs can be downloaded from: ftp://www.wikigadugi.org/wiki/xml/wikix-logs.tar.gz Jeff
