Some lovely practical advice here.
After 20 years of programming I still consider myself an average programmer and a junior many times a day. Technology is changing so rapidly I feel it is impossible to stay on top of it all. Take Angular for example, they will probably release 2 versions before I finish this post 
, only joking.
But developers need to hear these confessions because we have the impression that we should know everything and to realise you are not alone felling this way can make a big difference.
But now I am beginning to feel burnt out. It’s like running a marathon, I’ve hit my wall and doubting whether I can continue.
My 2021 resolution is to read more tech than I normally would (which to be honest has not been much, my bad). I am not going to change my tech stack but instead try and deep dive and get a better grasp of the concepts.
But I also lack a lot of the computing basics, the bigger picture as it were. Tunnels, Networking, VPNs, Protocols, Security, etc. It’s all been lost in the haze of time and I wish to brush up.
So with that in mind, I’m looking for good books around general computer systems basics that might bring me back to the future, or at least into this millennium. Does anyone have any preferred reading material? Some book they may even dare to call their tech bible ?
