I have embedded developement board (LPCXXXX) with me. I would like to do various experiments with that. I am not getting experiment ideas.
Please suggest me some good websites where I will get some good project/experiment ideas. I am looking for embedded system projects with source code in internet.
I am unable to find it.
Please help me where I will get embedded system project with source code (Video tutorial is an added advantage)
:-In tag I have added C because I did not find EmbeddedC tag.
Try Martin Thomas's ARM Projects site for a number of projects specifically for various LPC devices and also other ARM micro-controllers which could easily be adapted for LPC.
That's a rather broad question as you don't give much about what aspects of the embedded project you're looking for. The Kernel? The OS (making it small with things like busybox)?
But one good reference might be the Raspberry Pi project you might have heard about recently. It has it's linux kernel published, along with all the necessary OS components.

I want to try developing with ARM platform, particularly I'm interested in bare metal. I'm trying to start that using QEMU but this way of learning lacks comprehensive tutorials and it inevitably adds another level of complexity. Please, suggest a decent ARM development platform that meets the following requirements (sorted by descending importance):
Accompanied with a good step-by-step tutorial.
Provides basic input/output. I want to see some blinking and be able
to press some buttons on it. Additionally, having a digit display
(like on a calculator) or even an lcd display would be wonderful
Provides at least some debugging capabilities.
Modern.
If you want to start of with ARM controllers , you can go for mbed.mbed boards come with LPC
1768 32-bit Arm controller. You need not know much about the underlying hardware to code as there are many builtin api's to work with GPIO's and to interface sensors.
You can follow the mentioned link for the same mbed

Ive been searching around and I couldnt find anything on how to really begin programming for the Odyssey 2. I thought it was be kind of fun to mess around with one, to maybe try and program a simple game. But I wanted to know how I could begin. Like for example what is the console coded with, assembly? C?
Is there any example code online? Are there some tutorials?
I have been trying to find some, but have had no success.
It has only 64-bytes of memory, so yes, you need to use assembly.
There is an open-source, well commented game Kill the attacking aliens which should help you get started. When in doubt, you can also check the source codes of Odyssey² open-source emulators o2em.
There is also a good deal of documentation of the system here (this page in particular).
It has an Intel 8048 CPU, so you're probably pretty much stuck with assembly language -- I don't know of any compilers that target an 8048, and with only a couple hundred bytes of RAM available (only 64 bytes of that for general-purpose use), it doesn't seem like a good target for a compiler either. There are a few 8048 assemblers around, mostly of them freely downloadable. You can also dig up a few Odessey 2 emulators if you do a little looking (again, at least some are free).

I need to write client and server applications for MS-DOS using C language.
I don't want to start from scratch and implement sockets.
Can you advice me library in which socket functionality is implemented and for which exist good manuals and examples.
I already tried mTCP library: I got source files from it, added sources from example file and tried to Compile in Turbo C, but it raises a lot of errors it will be very hard task for me to cope with them.
Try libnet. According to it's web page (http://libnet.sourceforge.net/) it supports DOS systems (djgpp compiler), though I personally haven't tried it on DOS.
There is also WATTCP: http://www.erickengelke.com/wattcp/
Have you tried that?

I'm doing a sniffing project and almost done with it. We are now planning to create a GUI for it. We have written the entire network programming project in C language on Ubuntu 10.10 platform. Any idea/tools with tutorials regarding how to create a GUI for these C programs?
Will the language/tool/platform used for creating the GUI affect the C source code?
Thank you
There are different libraries for creating GUI applications in Linux.
There is GTK+, which is the native widget toolkit for GNOME and which has a C API. There is also Qt which has a very good C++ API, and which is also available for Windows, Mac OS X and other platforms.
I would suggest using GTK+ . It was natively written in C so compatibility shouldn't be an issue. I used this to help me learn it when i was messing around with it.

I've got a C++ app that ships on Windows and OSX. It communicates with our backend using TCP (encrypted with OpenSSL, natch). I'd like to throw up some speed bumps for folks who are trying to reverse engineer the protocol and/or disassemble the executable.
Skype does an excellent job of this, which is why you won't find a lot of apps that speak skype. Here is a really good read about what it does: http://www.secdev.org/conf/skype_BHEU06.handout.pdf
I'd like some ideas about how to accomplish similar stuff our app. Are there commercial products that make code harder to statically analyze? What is the best way to invest my time to accomplish the goals I've listed?
Thanks,
Some simple suggestions for OSX:
Prevent gdb from attaching to your program
http://www.steike.com/code/debugging-itunes-with-gdb/
(this can be worked around, but will keep some casual explorers away)
Have at least some of the code in your product stored outside the text segment of the executable, for example in data, or in an external (encrypted) shared library.
Minimally protect any sensitive string data by not storing it in plain text. Run "strings" against your executable, and if you see anything that might be helpful to someone trying to figure out the protocol, encrypt it.
GCC's -fomit-frame-pointer option can make debugging more painful (but can interact badly with C++ exceptions).
If I remember correctly Skype is using something similar (maybe they pay them to implement it in Skype, who knows) to "Code Guards" described in:
