Roborealm

RoboRealm® is an application for use in computer vision, image analysis, and robotic vision systems. Using an easy point and click interface RoboRealm simplifies vision programming! Using an inexpensive USB webcam and the PC you already have you can now add machine vision to your robotic projects!

Image and/or video processing can be technically difficult. Home robots are continuously moving towards PC based systems (laptop, netbook, embedded, etc.) that have the power to support complex image processing functions. RoboRealm provides the software needed to get such a system up and running. We've compiled many image processing functions into an easy to use windows based application that you can use with a webcam, TV Tuner, IP Camera, etc. Use RoboRealm to see your robot's environment, process the acquired image, analyze what needs to be done and send the needed signals to your robot's motors, servos, etc.

For example, you can use RoboRealm to track colored objects, navigate with obstacle avoidance, identify fiducials that let you robot know where it is, and much more!

Jailbreaking / Hacking & Unlocking iPhones & iPods

Jailbreaking is the process to unlock the iPhone and iPod touch devices to permit the installation of third-party applications. It can also add ringtones or change wallpaper on iPhone. It opens up the file system of iPhone so that it can be accessed from the computer.

Some people after unlocking their iPhone or iPods start installing genuine software that are provided from Apple company. This can be a problem for all those who have unlocked or hacked their iPhones or iPods, because when you install any software that is provided by Apple, then that software before getting installed it checks if the iPhone or iPod was unlocked, it may check if you are using third party software on your device & if it is true then that software may lock your iPhone or iPod again or it may inform Apple company about it. However I am not sure about this but I and my friend think that this technique can be used by Apple to catch the culprits.

Hope you find this information lucrative. ;-)
