Unity3d 5.3.0 introduced JsonUtility class which will help you with JSON serialization and deserialization.

But, there are solutions: You can change a data type, for example, use System.String or System.UInt32 instead of System.Guid. But if you have a lot of code which uses your DTO objects it might be painful to refac...

At Novility, we have  found that we cannot log working time anymore.

[IoT] Connect Intel Galileo Gen 2 to Arduino Uno via nRF24L01

Guys from Newark element14 have sent me a nice dev board - Intel Galileo Gen2. I was curious because before, Microsoft declared that Windows 10 IoT Core will run on this board. I planned to run my previous benchmark on this board to see if it can beat Raspberry PI 2. Unfortunately, with the latest release they removed this board from the compatibility list :( But this is not a big problem because I have some plans about home automation and I can use this board in it. I have couple nRF24L01 modul...
