How to setup a service to execute automatically when beaglebone boots?

Suppose you are developing an application on beaglebone black, and after the debugging process is finished, now if you want it as a stand alone product then it is not possible directly. Because every time to run your program (in whatever language: C, C++, Python), you were triggering it to run the program by logging in via ‘ssh’ or direct GUI. But this way is not feasible for the actual product. The actual device should start operating itself as per required application, when it boots. We cannot use Laptop/PC that time. So here there is a way by which you can enable your Beaglebone to run your actual program when it boots. So it directly starts your application.

For example, you are creating a barcode reader device, then your beaglebone should be able to start accepting and processing data from barcode device directly right from the boot time. Continue reading

Raspberry Pi 2 arrives with quad-core CPU, 1GB RAM. Runs free Windows 10, but still same $35 price

The Raspberry Pi Foundation’s low-cost computer was an instant phenomenon upon its release in 2012, and now, just shy of three years later, it’s back with a new one. The foundation is today announcing the Raspberry Pi 2, an equally cheap, equally tiny computer that’s meant for use in electronics projects, assisting experiments, and teaching kids how to code.

There are two key changes on this new model: its processor is now a lot more powerful and it includes twice as much RAM. What doesn’t change is just as important: it still sells for only $35.

“It’s a major leap forward in terms of computing power for users,” says Mike Powell, a technology development manager for Pi distributor Element14. Powell believes that the Pi 2 will open up a lot of new opportunities because of its added computing power. “A whole wave of new applications are now possible,” he says.
