IE8 Rendering Issues

IE8 is a vast improvement on IE6 in terms of rendering HTML and CSS; however now and again there still seem to be some oddities compared to other browsers.

Having spent the best part of a day trying to debug the code which had been validated by http://validator.w3.org/ (as XHTML 1.1 Strict ) and http://jigsaw.w3.org/css-validator/ (as CSS 2.1), IE8 was still having trouble rendering the page and was drawing a div twice.

Ultimately it boiled down to an anchor tag being closed in short form. i.e. <a id="someAnchor" />. After changing this to <a id="someAnchor"></a>, everything worked fine and was bang on again in IE8.

Lesson learnt that if IE8 appears to be rendering incorrectly, check which tags are being closed in which way. Not saying this is the answer to every rendering issue in IE8 but it's something to look out for if HTML and CSS code is perfectly valid, rendering correctly in all other browsers (Chrome, Firefox, Safari, etc.), but getting screwed in IE8.

On a side note.... according to netmarketshare (http://www.netmarketshare.com/browser-market-share.aspx?qprid=2) 17.17% of users are still browsing with IE6 and 11.79% with IE7. Seriously, people should either upgrade or move to a different browser.

Which blog engine?

So the time has come to move to a more advanced blog engine for my blog. blogger.com , Google's blogging service, has served me well. It's incredibly easy to use and to get started with, along with having some great features such as inbuilt stats; however now I need a few more advanced features and greater control over the blog. There's a vast array of blog engines out there, some free, some paid for, some hosted, some self-hosted, and picking which one is best or the right choice could be a little bit tricky. This article from Mashable lists most of the main options and bigger players -  http://mashable.com/2007/08/06/free-blog-hosts/ . There are a few parameters that I've kind of decided on Ease of installation/compatibility and support with web hosts Simple to use. I don't want to spend ages clicking around just to add a post or format it. Feature rich and well supported. Most blog engines should have a fairly standard set of features now such RSS/ATOM fe...

EF CodeFirst Database.SetInitializser Requires Connection to 'master' Database Error

One of the features of EF CodeFirst is the ability to automatically drop and recreate a database if the model changes or if the database does not exist, which is pretty useful when just doing development work. In a web app this is done in the Global.asax file within "protected void Application_Start()" as per this post from Scott Guthrie -  http://weblogs.asp.net/scottgu/archive/2010/07/16/code-first-development-with-entity-framework-4.aspx . An example would be: protected void Application_Start() { Database.SetInitializer<yourdbcontex>(new DropCreateDatabaseIfModelChanges<yourdbcontext>()); AreaRegistration.RegisterAllAreas(); RegisterGlobalFilters(GlobalFilters.Filters); RegisterRoutes(RouteTable.Routes); } However when using the Database.SetInitializer and trying to rebuild the database, the following exception may be encountered, especially if using SQL Server Express: "This operation requires a connection to the 'master'...
