Anyone I know built an RPi cluster? Like those little 3-4 pi toy looking racks that would fit in a shoebox? They look very cute. But what exactly would you do with them?
Each time I visit Real Engineers™ in SV, I get an itch to do a baby version of whatever they’re doing. In this case I just spent a couple of days with engineers building multi-million dollar rack systems and I feel like making a multi-hundred-dollar rack system
You don’t see the rewards of using cheap hardware until you have enough of it to break. If you want to play with big parallelism like spark or something, just get a big AMD machine or use AWS and implement some algorithms in some MapReduce framework.
