How to avoid your emails from ending up as spam.


So you've create this great online app, you've opened it up for people to register, but then you realize one thing --  your emails are ending up in your user's spam boxes. How one service judges an email may differ greatly from another service.  Email filters generally calculate some type of "spam score" generated from their own algorithms based on a variety of factors, so the best thing you can do is to eliminate as many common variables as you can.

IE10 & ASP : _doPostBack is undefined & Exception message: Input string was not in a correct format.


IE10 is breaking older versions of ASP.NET. In my case, a client running ASP.NET 2.0 encountered the following problems.  Here are some quick fixes for them as well.

Note:  If you notice that your problem only occurs on IE10 (and not previous versions of IE), then you might want to try this first:

Simple add this meta tag to your site header:  

<meta http-equiv="X-UA-Compatible" content="IE=8" />

adding this tag will tell IE10 to run in IE8 documents mode (compatibility).  This may solve your problem as a short-term fix.  Long term ...

www.facebook.com not loading on my macbook, mountain lion


This is to share a solution to a problem that may affect Macbook users using Mountain Lion OS X and having problems loading www.facebook.com.

Two days ago, I suddenly found that I couldn't load www.facebook.com and ONLY www.facebook.com. I would get a timeout error trying to reach Facebook. Attempts to reach facebook.com (without the www) won't work since facebook.com redirects to www.facebook.com. All other sites worked fine. I have a Macbook Pro, using Mountain Lion OSX 10.8.

I tried every solution I could find on the net:
