Paul’s first post in a long while – I stumbled on this series of articles which are excellent if you happen to be developing and deploying embedded firmware.
Also if your job still has some hardware for which you’re somehow responsible (ie: you’re not 100% on someone else’s cloud service!) these are worth a read. While your employer might just be a consumer of the end product – shipped versions of firmware on hardware that you buy / already own, it is worth understanding what is involved in making that firmware and shipping updates.!
