Each of these commands will run an ad hoc http static server in your current (or specified) directory, available at http://localhost:8000. Use this power wisely.

# Add this script to your cloudformation directory (we have ours in the project root).
# Then set up a build step in Team City that executes the custom script:
#
# [[ -f ./cloudformation/validate-cloudformation.sh ]] && ./cloudformation/validate-cloudformation.sh
#
# That way branches without the script will still build.

In search of Idiomatic ESLint

I'm in the process of creating a new web app boilerplate, and I need to give it a lint config. Kyle Simpson convinced me I should look at ESLint instead of JSHint, so now I have to figure out how to configure ESLint to my liking. My liking means as idiomatic as possible.

To that end, I will give an unnamed JavaScript related prize (of real value) to the person who can show me an .eslintrc that most closely matches the idiomatic style I recommend in Appendix A of "Programming JavaScript Applications" (O'Reilly).

Candidates

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
