Crystal MTs (Multi Threaded schedulers)

Goals:

• developers must only care about fibers and channels;
• crystal runtime should start 1 upto N threads;
• each thread can take & resume any fiber in the loop;
• channels as user-code sync primitives;
• also propose fiber-aware mutex/monitors;
• additional sync primitives (e.g. IO events, ...)

"A little bit of slope makes up for a lot of y-intercept"

01/13/2012. From a lecture by Professor John Ousterhout at Stanford, class CS140

This guide assumes that you recently run brew upgrade postgresql and discovered to your dismay that you accidentally bumped from one major version to another: say 9.3.x to 9.4.x. Yes, that is a major version bump in PG land.

First let's check something.

brew info postgresql

The top of what gets printed as a result is the most important:

Rich Hickey on becoming a better developer
