Having a lot of ram is nice, but every time I read that people need at least 8gb for development, I ask myself what it is that they are running. I am running chrome, sublime, docker, hbase, redis, memcached, mongodb and probably some more stuff and I hardly swap with 4gb, or maybe I just do not realize it because of my ssd. Am I missing some ultra useful, memory annihilating dev tool?
Chrome, IntelliJ IDEA, and 4 Java modules running simultaneously goes through 8gb without any hesitation. Hell, IntelliJ alone uses over 4gb sometimes.
And I thought my Eclipse install was a hog, weighing in at 500MB's through 1GB sometimes.
