  • iOS Swift Detecting Device Rotation

    How to detect device rotation event in iOS Swift 3: Detecting device rotation is not a big secret but doing this in a clean way is important. I mean adding and removing the observers in correct time/place. Many developer are adding  observers without removing with exit. This leads memory leaks and performance issues.   override func…

    Using Real 1 Bit Boolean Variable For Arduino Memory Efficiency

    We love Arduino we want to make some fancy project  but in this beautiful playground we have some limitations.  32K Programming memory is quite enough but 2K SRAM is becoming insufficient  when we use  lot of variable, especially if we don’t use the variables in efficient way. For example; if the variable will have a value between 0 and 255 ve use…
