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

// Aperture library extractor -- copies all source images from a apimportgroup inside a aplibrary
// into any folder.
//
// Step 1. Create a new folder somewhere, for instance in ~/ap-rescue
//
// Step 2. Run this program, giving it the apimportgroup as the first argument and your
//         destination directory as the second argument.
//
//   e.g.  node extract-aperture-images.js ~/'Pictures/Aperture Library 2000.aplibrary/Arkivet.approject/2006-01-15 @ 03:57:21 PM - 1.apimportgroup' ~/ap-rescue

Make it real

Ideas are cheap. Make a prototype, sketch a CLI session, draw a wireframe. Discuss around concrete examples, not hand-waving abstractions. Don't say you did something, provide a URL that proves it.

Ship it

Nothing is real until it's being used by a real user. This doesn't mean you make a prototype in the morning and blog about it in the evening. It means you find one person you believe your product will help and try to get them to use it.

Do it with style
