Update 2022: git checkout -p <other-branch> is basically a shortcut for all this.

FYI This was written in 2010, though I guess people still find it useful at least as of 2021. I haven't had to do it ever again, so if it goes out of date I probably won't know.

Example: You have a branch refactor that is quite different from master. You can't merge all of the commits, or even every hunk in any single commit or master will break, but you have made a lot of improvements there that you would like to bring over to master.

Note: This will not preserve the original change authors. Only use if necessary, or if you don't mind losing that information, or if you are only merging your own work.

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

Secure sessions are easy, but not very well documented.  
Here's a recipe for secure sessions in Node.js when NginX is used as an SSL proxy:

The desired configuration for using NginX as an SSL proxy is to offload SSL processing 
and to put a hardened web server in front of your Node.js application, like:

[NODE.JS APP] <- HTTP -> [NginX] <- HTTPS -> [PUBLIC INTERNET] <-> [CLIENT]

Edit for express 4.X and >:  Express no longer uses Connect as its middleware framework, it implements its own now.
