Is there any open source code for creating a piano keyboard with sounds for ios? I have looked but have not found one, or offer a good recommendation were to start, AVAudioPlayer. or systemSoundID

Here is one you can try. It is something I started a while back and have not had time to finish because of my day job.

I found this great tutorial, it is a little advanced but perfect for learning. I already have a simple version up and running using this tutorial
http://mobile.tutsplus.com/tutorials/iphone/ios-sdk_playing-systemsoundid/

I have tried a few solutions, and eventually used this piano keyboard for iOS, since I couldn't get rid of the lag which is crucial when using it as part of a multitracker for timing issues (an app I'm working on).
I learned a lot from going over the code and through the support I got from the author, so even though it wasn't free I was very pleased with it.

I have big project (not mine) in java EE , at first when I looked at it there were many many classes, when I try to understand a method of class there is another class which calls method in it and again and again, It's really hard to understand the code (there is no documentation) is there any tool to help me ?
Unfortunately there aren't really any tools to help with this, the most that you can hope is that someone created a UML Doc for the code you're viewing. However, as this is not the case, the best place to start is at the main method and slowly traverse the setup. I find that it helps to keep notes and diagrams, describing (functionally) what things do and in what order they happen.

Working on building out a Web2Print product I need some kind of editor that will allow a user to manipulate graphics and ultimately generate a PDF. There are plenty of HTML 2 PDF APIs available but I was hoping someone might have experience with something a little more integrated and suited for dealing with graphics/fonts/text?
In PHP the best opensource option is TCPDF http://www.tcpdf.org/
I wanted to answer this and update everyone on the solutions that I found. Through the Magento extension store I was able to find several commercial (although still very reasonably priced) solutions:
http://www.zetaprints.com/ and http://layoutbuddy.com/ look like the most full featured and supported (as well as no up-front licensing.)
Thanks for all of the responses!

I'm looking for a simple way to tell if an app is using the Okuma API. There are several applications running on a control and I don't see any indication. I've tried renaming the Okuma API dll's and I can make some of them crash by not being able to find them but that can't be the best way.
I'm writing my own app too, I want to follow the standard. Is there any built in splash screen or standard way to show an app is using the API? (Something like Intel-Inside but Okuma THINC Inside, etc) I've tried searching for the Okuma logos and I see several different versions being used but none that signify anything about API and none that really look standard for indicating API usage.
At this time there is no official logo for the purpose your describing.

I'd like to be able to analyze an image captured with the iPhone camera and generate survey results (multiple choice). Apparently what I'm interested in is called OMR, Optical Mark Recognition (not OCR, Optical Character Recognition which is more sophisticated).
Does anyone know of any OMR libraries or source code that can be used to build such an iPhone app? And if not, any suggestions on rolling my own would be appreciated. Thanks for the help in advance.
Maybe this is of interest to you:

It's from the developer of Sudoku Grab, which recognizes sudoku grids from the camera. It should definitely be useful to you.

I read this book:
Head First Object-Oriented Analysis and Design
Now i am looking forward to find a Software that make it easy to collect all my Ideas etc (specific Software for OOA).
At the moment i am using my Whiteboard to collect/design Ideas etc. Afterwards i am taking pictures of it and add text to our Wiki/Trac.
At school, we're using Objecteering, which is easy to use, integrated to Eclipse, but not free.
IMO blank paper is a must, but not always the easier to share and to edit.
Install mediawiki (the stuff that powers wikipedia, don't settle for anything less you will need the full feature set eventually) and put all your ideas in there. This makes it easy to refine them and to improve then as time goes by.
