Windows 10 - Display driver has stopped responding and has recovered.

There are many reasons this happens but in my case it only happened when I was using Firefox.  I corrected the problem using the following steps: Navigate to Options>Advanced>General.  Under ‘Browsing’, uncheck the "Use hardware acceleration when available."  That should fix your problem.  As an added benefit Firefox seems to respond faster after the change.

PHP Error - function.session-start: Cannot send session cache limiter - headers already sent

If you have the session_start(); on the first line and the error message points to line 1 as where the error is, it means your PHP file is BOM encoded.  To repair your file use a program like Notepad++ then select > Encoding > Convert to UTF8 without BOM.  Then go back to Encoding and verify that Encode in UTF8 without BOM is selected.  If so, Save your file then upload it and view in your browser.  The error should be fixed.

In HTML 5 validating an input is easy; all you have to do is add a "required" attribute to your text box.  ASP.NET has plenty of built in controls for validating which all add overhead to your page in the form of auto-generated JavaScript.  On the internet less is best however. Plus why write lots of code (sort of) when you don't have to?
