📟 Tomu - open-source ultra tiny development board
An ARM board that fits inside your USB connector
Tomu is user-programmable, has two buttons and two LEDs, and can be used for everything from a hobbyist device to a U2F security token.
Tomu is open-source. You can download the hardware schematics, make your own circuit board, and inspect how all the pieces work together. You can download the software source code and trace programs as they run.
Tomu is flexible. Maybe you want volume buttons on the side of your laptop. You can load software onto Tomu that uses the two buttons for Volume Up and Volume Down. Or maybe you want to be able to put your computer to sleep or wake it up from a USB hub. With Tomu, you can turn any USB port into an input device simply by uploading new software to it.

📃 Tradeoffs Between Edge Vs. Cloud
Analytical article on the latest tendencies in IoT field
Edge computing is on the upswing because of the process technology, innovations in the AI hardware design, and because we are doing processing in fixed point, like 8-bit, you can put a lot of processing power on devices like mobile platforms.
But computing at the edge also has limitations. When you cannot do something on the edge, because devices are not powerful enough, you have to do them in the cloud. The real value of the cloud, in this case, is a broader analysis of processed data that is less time-sensitive. An edge system may need to do its own analytics for its primary task.
An example is a drone that is examining an electrical tower. It may detect something and immediately has to act on that to figure out what the issue is. When it returns to its home base, it may transfer a lot more data that you want to analyze in the cloud. There are different layers of processing that could be done.
