Let me start by saying I’ve built several REST APIs. Good API design falls into two categories (1) Clearly following good object oriented design principles and (2) clearly following the HTTP 1.1 specification. My intent is that by viewing antipatterns, examples of what not to do, you can come away with a good sense of what should be done, and I’ll even give a few good API Design examples later.

Memory management in low power embedded systems

Power consumption for mobile systems designers have become a first class concern alongside performance and design. Typically the lowest power processors are 4 bit or 32khz processors with extremely lower power cycles. Memory transposition between program and SRAM on Arduino, or for example between the processor core and Icache on other systems, 50 to 80% of runtime power volatility can come from memory traffic caused by transfers between off-chip and on-chip memory.
