AppShopper

If you have a iOS device, this is a fantastic site! You can see the apps that dropped in price, got an update or find new applications. I have created an account, and can add programs that I want to a wish list, and get an alert if it drops in price. At the same time I have added RSS feeds for new free apps and apps that drop in price. That way I get some of the apps I want cheap and discover new interesting apps. I hope to post some of my discovered apps on this webpage, as I find some really good apps.

LINQPad

I discovered this tool a long time ago, but did not find it that useful, since I already is able to write LINQ to SQL queries in Visual Studio. Even in the Express Editions of Visual Studio I am able to write them with intellisense, something you have to pay for when using LINQPad. But recently a colleague showed me some more features that made me buy it.
