If you want to learn Scala, I’d suggest:

Install IntelliJ + Scala Plugin
Don’t do the Coursera courses yet.
Don’t do the “red book” Functional Programming in Scala yet.
Do: http://underscore.io/books/
- Essential Scala
- Essential Play
- Essential Slick
Do Scala for the Impatient: https://www.amazon.com/Scala-Impatient-Cay-S-Horstmann/dp/0321774094
The Neophyte’s Guide to Scala http://danielwestheide.com/scala/neophytes.html

The introduction to Reactive Programming you've been missing

This tutorial as a series of videos

If you prefer to watch video tutorials with live-coding, then check out this series I recorded with the same contents as in this article: Egghead.io - Introduction to Reactive Programming.

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns
L2 cache reference ........................... 7 ns
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns             
Compress 1K bytes with Zippy ............. 3,000 ns  =   3 µs
Send 2K bytes over 1 Gbps network ....... 20,000 ns  =  20 µs
SSD random read ........................ 150,000 ns  = 150 µs

Read 1 MB sequentially from memory ..... 250,000 ns = 250 µs

Allow routing allocations:

curl -XPUT localhost:9200/_cluster/settings -d '{
                "transient" : {
                    "cluster.routing.allocation.enable" : "all"
                }
        }'

	import SimpleHTTPServer
	import SocketServer
	from time import sleep

	PORT = 5000
	SLEEP_TIME = 6


	class SlowHandler(SimpleHTTPServer.SimpleHTTPRequestHandler):
	def do_GET(self):

	// Check whether --offline was passed to gradle and set it in the test configuration's system properties
	test {

	if(gradle.startParameter.isOffline()) {
	systemProperties 'TESTS.ARE.OFFLINE' : '1'
	}

	}

	openssl s_client -crlf -connect imap.gmail.com:993

	// Use Gists to store code you would like to remember later on
	console.log(window); // log the "window" object to the console
