Which licence to release code under?

[Cheetah Designs]

I have some open source code I want to release but I don't want to read through a load of licenses, so for those that already know them, I want one which have the following:

- they can use it for whatever they want in whatever software they want
- copyright/license must remain intact on the source code

and if possible:

- any copyright/release notes must include my license/copyright

Thanks.

Just remembered, I used someone elses code in my software which has the following licence:

What do I have to do to adhere to this licence? When I upload my code so I simply append the licence to the top of all the classes that are from this licensed software?

Do I have to include anything with my actual software itself?
