I am running a project on cubieboard and it is fine enough. But current project require a same configuration with embedded GPRS(with sim card holder) and GSM module. If I implement it with USB 3G dongle and GPS device the cost is not acceptable. I want a embedded solution which can save cost.
Can any one tell me cost effective way to implement GPRS and GPS in cubieboard ?
or
Alternative Single board computer with same feature like 4GB NAND, ARM Processor and Linux Kernel (u-boot) with GPRS & GPS module support ?
A (relatively) cost-effective way I've came across is this:
http://www.dfrobot.com/wiki/index.php/GPS/GPRS/GSM_Module_V3.0_%28SKU:TEL0051%29
It is arduino compatible, however, I believe that you are experienced enough (or willing to become) to configure it for the cubieboard.

I am learning to customize the Linux kernel to make it portable on embedded systems. To test my customized kernel , i want a completely open sourced ARM board. I investigated the Raspberry pi but some it's firmware (i.e. "start.elf") is not open source. Can anybody name an ARM board which is completely open source?
Also are there any such board whose ROM/AVRAM contents can also be replaced?
Thank you !
If by "completely open source" you mean open source bootloader, kernel and OS (correct me if I'm wrong), then I would recommend one of Beagle family boards -- they are inexpensive, user friendly and have a good community support. Their open source stack consists of U-Boot, Linux kernel and one of few available distributions. If you need advanced features, check out EVM's by Texas Instrument, but they cost much more.
Jetson-TK1 from nvidia, is a developer platform,
does have u-boot loader, Linux Kernel and rootfs,
The board layout is also shared, you can recompile things for you.
It comes with 2GB RAM, a 2.3GHz Quad core processor, with GPU that is ready for CUDA kind of high level programming

I'm writing a Mathlab programe for get input from a serial port.
serPort = serial('COM5','BaudRate', 57600);
fopen(serPort);
.....
Now i want to check this programe with virtual com port(COM5) and sent data to the port virtually.
Can someone suggest a software to do this.
(Everything is in the same computer)
Try VirtualBox, it creates a virtual machine in which you can virtualize the com port (to a file if you want).

In my organization, we have people at several locations in the US and abroad. For Lunch & Learn sessions, I sometimes download educational videos (Creative Commons License) and would like to broadcast them to participants at our other locations.
I have being using GotoMeeting, but the results are poor -- the remote videos cannot keep up with the broadcast video, even though we have very fast Internet connections (50/20 at most locations).
Is there some software, either free or low cost, that I can install on my Mac (OS X 10.8.5) that will allow me to stream the videos, with me having control over pausing, etc. (I pause when when someone wants to discuss some aspect of the video)? All of the participants are on a VPN and can access my Mac's IP address.
I would rather not have to set up a whole web application to do this.
Although my preference is for Mac OS X software, Windows software will also work for me.
VLC media player is a free tool on both Mac OSX and Windows which can broadcast a video stream. I have never used this function myself though, so I can't explain in detail how to use it.

I'm interested in finding out how customers use features in my Cocoa application.
I want to build up statistics on which features people use and how they use them, so that I can measure the value of features I'm implementing.
I'm building a desktop app to run on Snow Leopard.
This feedback of course will be opt-in and anonymous.
Does anyone know of any frameworks that have been developed that can achieve this without me having to write stuff from scratch?
Might want to look into Flurry Analytics. It's "free" and will track just about anything you're interested in.

I am currently in the process of locking down the network communication protocols that are available for use on given Windows application platform.
Can you suggest a freely available tool that will allow me to monitor/identify the commuications protocols that are in use i.e.
TCP/IP

https
FTP
SFTP
Wireshark - this should do everything you need.
Apart from Wireshark already mentioned by Cybergibbons, you could use TCPDUMP.
Although Wireshark is way better for what you need.
