• http 301 redirect from htaccess to domain host

  - by neilc

  Hi I have the following in a .htaccess file redirect 301 /page.php http://domain.com/page Which works fine and as expected. I want to be able to redirect the following http://domain2.com/page.php to http://domain2.com/page or http://domain3.com/page.php to http://domain3.com/page or http://domain4.com/page.php to http://domain4.com/page So basically whatever the domain name is, I want to redirect to it. But the catch is I want to use a 301 redirect. Is this even possible ? Or should I be using RewriteCond and RewriteRule ?

• Tabbed javascript widget for a Rails app

  - by neilc

  A user registers on our Rails app and they're given javascript to embed a widget in their website. The widget has a tabbed interface, like the JQuery tabs http://stilbuero.de/jquery/tabs_3/. iFrames have been tested, but the widget form factor and cross-domain policy negates the use of iframes. The widget is very dynamic and will often update the DOM with new content - and because of cross-domain policy, it looks as though JSONP is necessary. I understand that 'widget.js.erb' needs to create the widget layout, reference a stylesheet, render the tabs, etc - but once a tab is clicked, how does the widget request the content from the Rails app and render it in the DOM?

• Strategy to structure a search index in a relational database

  - by neilc

  I am interested in suggestions for building an efficient and robust structure for indexing products in a new database I am building (i'm using MySql) When a product is entered through the form there are three parts I am interested in indexing for searching purposes. The product title The product description Tags The most important is title, followed by tags, followed by the description. I was thinking of using the following structure CREATE TABLE `searchindex` ( `id` INT NOT NULL , `word` VARCHAR( 255 ) NOT NULL , `weighting` INT NOT NULL , `product_id` INT NOT NULL , PRIMARY KEY ( `id` ) ) Then each time a product is created I would split apart the title, description and tags (removing common words) and award them a weighting. Then it is trivial to select out the words and corresponding products and order them by weighting. Is there a better way to do this? I would be worried that this strategy would slow down over time and as the database filled up.

  I've been looking at how some jQuery plugins work and I've seen the following acting as a closure around the whole plugin $(function(){ // plugin code here }); (function($){ // plugin code here })(jQuery); What is the difference between these two ?

• Subversion unable to merge changes when using Dreamweaver

  - by neilc

  I've got a project running and we're using SVN as the version control. There are 3 devs on it. Dev1 = OSX + Textmate Dev2 = Windows 7 + Dreamweaver (plus tortoise svn) Dev3 = OSX + Coda Case 1 (expected): Dev1 and dev3 work on a file called signup.php. They work on different parts of the file. Dev1 commits it and dev3 updates their copy. signup.php is merged as expected. All good. Case 2 (not expected): Dev1 and dev2 work on a file called signup.php. They work on different parts of the file. Dev1 commits it and dev2 updates their copy. signup.php is always in conflict even though different parts of the file are worked on. This is not the expected behaviour experienced by dev1 and dev3. This works boths ways and each time dev1 updates dev2's changes he gets conflicts too. But never with dev3. Could this be down the way Dreamweaver is saving files ? Perhaps character encoding. We are all working in UTF8. These constant and unnecessary conflicts are becoming a massive distraction. Help !
