Excluding Cocoa (and its NSThread), what multithreading libraries would you recommend?
The application's engine must run on multiple platforms (Windows, Linux, MacOS, iPhone), and be multithreaded. Abstracting the library to compile against platform-specific MT libraries is possible, but incurs an extra layer of overhead and complexity.

NSOperation works fine. As an added bonus you get a thread pool for free, and can setup a dependency chain between operations.

How about something in the C library area?
e.g libapr: http://apr.apache.org/docs/apr/1.3/group__apr__os__thread.html
or glib?
http://library.gnome.org/devel/glib/stable/glib-Threads.html
Regards

I would start with Grand Central which was recently open-sourced: http://libdispatch.macosforge.org/

I'm doing a project where I need to analyze the differences between functional programming and imperative programming. I'm using Scala since it's a multi-paradigm language, for a fair comparison.
Using languages that have a front-end on gcc, pin and perf(hardware) are suitable tools to do these comparisons, but now on Scala, I'm not finding substitutes.
I'm not interested on microbenchmark that only observe the time it took to run the algorithm. Since it's a conway's game of life implementation, a number of memory access is required and so on. I'm grateful for any help
I would recommend ScalaMeter. It is a microbenchmarking tool, but it does what you want by running the code multiple times, and removing the effects of JIT compiler warm-up, garbage collection, etc. It can also be configured to report memory usage, etc.

I know that there are exist established frameworks written in Scala for web development (Lift and Play).
I wonder if there are any frameworks for desktop development as well(even in early beta stage). What I'm after:
- Application workflow
- Custom ui components
Scala comes with Java Swing wrapper, and you could also use SWT (just like you could use any other Java library in Scala). They are both suitable for desktop application development.
JavaFx is comming, so try ScalaFx

I am trying to convert word(.doc) into PDF on iOS device. Is there an opensource solution where I can use as a C/C++ lib or something?
There really is no conveniently open-source library that will do this for you: you may get some mileage out of WvWare but I've never seen it used on iOS and I'm not sure what platform dependencies it may need.
If your iphone is connected to the net, then you can call a Docmosis web service to do it. You need to sign up though.

are there any image effects (e.g. lomo, watercolor, sketch ...etc) libries can be used on mobile device and suitable for mobile device?
There are libraries like JJIL, simple-iphone-image-processing, JH labs, imageMagick porting to iphone and opencv have been mentioned in various previous posts.
I want libraries that I don't need to care about the algorithm of effect, but lots of libraries mentioned above are this type of libraries.
What I need are libraries that already have done effects functions and I just call the functions to apply effects on photos (It is ok to set parameters and attributes by myself when I use it).
Are there any more suggestions?
Free is good, commercial would be fine.
Thank you.
You could try the effects API from Aviary. Here: http://developers.aviary.com/
I never used it though, so I can't say if that's exactly what you are looking for.
Potentially worth your while:
OpenCV
Simple iPhone Image Processing

I'm looking for a role-playing game framework which fulfills the following critera:
Open source / Free for non-commercial
Targeted language doesn't matter as long as it's not too obscure (C# or Java would be great)
The framework doesn't have to provide any graphics, sounds or other "low level" stuff
The framework should support complex, non-linear story lines (like Fallout 1/2/3)
The character should be highly configurable (again like Fallout or Dragon Age)
Support for a party would be nice
Check out GemRB, a port of the Infinity Engine (i.e. Baldur's Gate). It's licensed under the GPL and written in C++ and Python if I'm not mistaken. Since it's based on the Infinity Engine, I would assume that all of the last three requirements apply as well.
