Welcome to Rosetta Code! I founded RC around a year ago, and still do most of the administrative work. Thanks for your code contributions. I'm curious, though, how did you hear about RC? --[[User:Short Circuit|Short Circuit]] 10:44, 23 February 2008 (MST)
:Hi, thanks. I heard from a forward message posted at Digital Mars D newsgroup about a month ago. -[[User:Badmadevil|badmadevil]] 03:03, 24 February 2008 (MST)
 
== Theme problems ==
Hi there, I'm really not seeing the issues you're reporting about the new skin. <del>If you could, post the browser version as well, as I see neither of the problems you've listed in the ones I'm testing with (FF3, Opera 9.5, IE7)</del> I'm really not seeing the issues you're talking about. Perhaps your font size is larger than normal? Ctrl + 0 or View > Zoom > Reset.

:oops... then my browser setting problem is the most possible explanation, sorry for the extra work. (btw, in my FF3, by changing zoom, it only affect the size of top-left logo's ''Rosetta Code'' text if ''zoom text only'', else everything is proportional) -- [[User:Badmadevil|badmadevil]] 04:08, 23 June 2008 (UTC)
:: This should be fixed. Give the skim another try. --[[User:Short Circuit|Short Circuit]] 00:14, 14 February 2009 (UTC)

== Not Implemented Tasks by Language ==
 
Hello. IIRC, it has been mentioned an idea to display a page of tasks not implemented by a specific language (It is from [[User:IanOsgood|Ian Osgood]]'s [[Rosetta_Code:Wiki_Wishlist|wishlist]]), it seems no such page at Rosetta Code yet. I've coded a dirty hack of such page using client-side javascriptPHP. It<br use/><br xmlhttprequest/>This toversion getshould thepreserve contentsRosetta ofCode's Solutions_by_Programming_Taskpages &look theand language specified page that contains tasks such language has been completedfeel, thenand bymay usingbe RegExp, extracting links under some specify id/tag, the links of set different of these 2 page arebetter tasksintegrated thatinto notRC implementedsite.<br /><br />''Sources'':
''Bugs fix notes :''
*When PHP flag <i>allow_url_fopen</i> is enabled, it is possible to read contents from RC Site via local server. Then, by directly testing with RC Site, many bugs were found;
*''fixed'', it seems that articles in tasks or languages' pages have at least 3 version of url. In most cases, they refer to the same file, but it seems some are not (may be re-direction?). Previously, some url can be accessed while other cannot, if only using one version of url; now all 3 version is tried. The version of '/w/index.php?title=' has highest priority, so that page like C++ will not mistaken by C page;
::''changed'', it seems I'm wrong again. All pages can be accesses by '/wiki/Category:' version's url, only that to not mistaken C++ page with C page, url extracted from RC page have to be encoded 2 times. In most case, this '/wiki/Category:(encoded-url)' can reach the page correctly, only pages like ''PL/I'', ''PL/SQL'' need 1 decode. No more other version of url is needed. -- [[User:Badmadevil|badmadevil]] 09:14, 17 June 2008 (MDT)
*''fixed'', previously, required link nodes to be got by xpath are assumed to be inside a table, but it is found that language page having 7 or less task completed didn't use a table; the later case is dealing with another proper xpath;
*some pages have not any task completed, eg. assembler, pike, JoCaml. They are treated as error loading page, rather than display all tasks from Task-list page;
*''unsolved'', there are unknown errors on parsing pages of ''JScript.NET'' & ''Visual Basic.NET'' as DOM. They can be load as DOMDocument (so that it is not a problem of url, eg.wrong encoding of url string), but can't get the required Node by getElementById inside the DOMDoc;
::''fixed'', it is really a problem of wrong encoding, the 'dot' is not properly encoded, and the page loaded I said previously is the create new articles page. It has been fixed. All bugs should has been fixed. -- [[User:Badmadevil|badmadevil]] 12:22, 16 June 2008 (MDT)
*''Usage'', this version need not config, as long as allow_url_fopen is enabled. Place this script in a server (local server or RC Site) some where can be access from www, and that is it.
*Tested with PHP 5.2.1
