Building an LTE Access Point with a Raspberry Pi
In one of my last experiments I replaced my crappy T-Mobile (now Magenta) 4G modem/access point with an OpenWRT-based cheap travel router and a 4G USB LTE modem.

FPGAs Have the Wrong Abstraction for Computing
Verilog is the de facto abstraction for programming today’s FPGAs. RTL programming is fine if you want to use FPGAs for their traditional purpose as circuit emulators, but it’s not the right thing for the new view of FPGAs as general-purpose computational accelerators.
