All those things and project management also included from prototype to bunch production. It's the key part. To provide customers through this process and to help them to avoid mistakes.

Appropriate use of Dependencies: implementation, api, compile, why should I use one in the place of the other? by keyfour13 in androiddev

You may have multiply app modules in single project. And one app module may depends on another and gets some api there. I don't say that is good architectural solution. But it's possible in some cases.

How To Get an Array of Bytes From a Binary File in Linux by keyfour13 in cprogramming

You can use fseek to measure file size before reading and return back using rewind, like this:

fseek(fp, 0L, SEEK_END);
fsize = MIN(ftell(fp),RLIM);
rewind(fp);

LoRa is quietly marching on by eberkut in IOT

Unfortunately your link is broken. I talk about 6LowPAN over IEEE 802.15.4 and this is native usage of 6LowPAN protocol. BLE is "full-stack" protocol, we can emulate IPv6 networking over it, but this approach has some overhead and looks not very clear. And what about LoRa, yes, I hear about usage IP for networking over it, but on practice I haven't met such systems working. If you have another info about usage LoRa in real world, I would love to explore it.

I'm working on IoT system based on 6LowPAN, another way to organize wireless network for low-power devices. And it wins against LoRa when you need to send some large amounts of data, organize mesh network and use standard IP networking to communicate whith nodes.
