new tutorial on acid-state, ixset, and lenses

Hello,

I just uploaded a new tutorial which covers three distinct, but related topics:

• acid-state - a native Haskell, noSQL, RAM-cloud database
• IxSet  - a multi-indexed collection type (similar to Data.Map but with support for  multiple keys)
• data-lens - a library which provides syntax that makes it easier to update nested records and other data types

The tutorial is available here:

http://happstack.com/docs/crashcourse/AcidState.html

The section on lenses is a great applied introduction to the concept which requires no understanding of Happstack, acid-state, or IxSet. So, even if you don't care about acid-state, you may find it useful if you have ever wondered what the heck lenses are.

happstack.com: now less evil

If you experienced some outage today trying to reach happstack.com, it is because we very ungracefully transfered our domain from the evil pro-SOPA godaddy to the less-evil anti-SOPA namecheap. Yay!

You are probably already familiar with SOPA/PIPA, but if not, here is some more information:

The DNS changes have probably propagated to you by now, but if not, they should in the next 24 hours.
