Latency numbers every programmer should know

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

Jenkins setup

I just had to set up Jenkins to use GitHub. My notes (to myself, mostly):

Detailed Instructions

For setting up Jenkins to build GitHub projects. This assumes some ability to manage Jenkins, use the command line, set up a utility LDAP account, etc. Please share or improve this Gist as needed.

d3.js polybrush.js

Forked from: https://gist.github.com/gtb104/3667340

Here's a d3 plugin that allows you to create a polygon selection. You instantiate it just like d3.svg.brush.

var brush = d3.svg.polybrush();

It has an extra public method that 'brush' does not, and that's 'isWithinExtent(x, y)'. You can use this method to test if a given point falls within the drawn extent.

if (brush.isWithinExtent(x, y)) {
 console.log("I'm inside!");

Securing ExpressJS

tl;dr

  1. Don't run as root.
  2. For sessions, set httpOnly (and secure to true if running over SSL) when setting cookies.
  3. Use the Helmet for secure headers: https://github.com/evilpacket/helmet
  4. Enable csrf for preventing Cross-Site Request Forgery: http://expressjs.com/api.html#csrf
  5. Don't use the deprecated bodyParser() and only use multipart explicitly. To avoid multiparts vulnerability to 'temp file' bloat, use the defer property and pipe() the multipart upload stream to the intended destination.
