NOTES

AppleScript is a rather peculiar scripting language to learn.

Open all files with git merge conflicts in MacVim

git diff --name-only | uniq | xargs mvim

When git encounters a merge conflict, e.g. during a rebase, it drops you back into the shell with a dirty working directory. I like this one-liner for opening all files with a merge conflict in MacVim.

Once you're in Vim, you can then switch between the files with :n and :prev, or another favourite: :w | n (save current file and open the next command line-supplied file).

UPDATE: see below for a version that works with real terminal commands.

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
