If you really want to stay relevant to what all the big boys are playing with these days, you'll learn ARM. And maybe a sprinkling of FPGA with an eye to ASIC implementation. Smaller microcontrollers are being used, but ARM is where everything is happening, if you want to base a career around embedd...

I'm hopeful that these are resolved, but if anyone knows how to guarantee that x random small office network will have 100% uptime, I'd appreciate your letting me in on the secret (bonus points if it doesn't cost anything). Use straightforward, basic hardware (i.e. a simple DHCP/DNS and some switch...
