For my projects I tend to prefer the ISC License, it's very simple and the
preferred license of the OpenBSD project. Its only restriction is 
so in this sense it would be most akin to a CC-BY license. Some people 
refer to
it as a 1-clause BSD license, and for use in commercial products 2- and 
BSD licenses are likewise very straightforward.

If you are interested in weaker forms of copyleft the LGPL and MPL2.0 may be
good to think about. The LGPL allows dynamic linking with proprietary 
works, but
a statically linked program is subject to the LGPL. The MPL2.0 as far as 
I can
tell is per-file copyleft, where changes to the licensed files must be made
available but cannot affect the license-status of any linked program. Unlike
earlier versions of the MPL and the CDDL, MPL2.0 is specifically 
designed to be

Copyleft licenses would be the closest analogue to the CC-BY-SA that you're
familiar with.

If you want to get your software into the Apple App Store you might have
trouble using the LGPL because of its relinking provisions. The GPL is
definitely banned. MPL2.0 and BSD-style licenses are ok however.

Please note this is just off the top of my head and I am no expert.
