How to move to a fork after cloning
So you've cloned somebody's repo from github, but now you want to fork it and contribute back. Never fear!
Technically, when you fork "origin" should be your fork and "upstream" should be the project you forked; however, if you're willing to break this convention then it's easy.
* Off the top of my head *
1. Fork their repo on Github
2. In your local, add a new remote to your fork; then fetch it, and push your changes up to it
git remote add my-fork git@github...my-fork.git

Latency Numbers Every Programmer Should Know
Latency Comparison Numbers (~2012)
----------------------------------
L1 cache reference 0.5 ns
Branch mispredict 5 ns
L2 cache reference 7 ns 14x L1 cache
Mutex lock/unlock 25 ns
Main memory reference 100 ns 20x L2 cache, 200x L1 cache
Compress 1K bytes with Zippy 3,000 ns 3 us
Send 1K bytes over 1 Gbps network 10,000 ns 10 us
Read 4K randomly from SSD* 150,000 ns 150 us ~1GB/sec SSD

Raven.js configuration for logging JavaScript exceptions to Sentry (https://getsentry.com/). Without the added ignore options, you'll quickly find yourself swamped with unactionable exceptions due to shoddy browser plugins and 3rd party script errors.

My personal tmux cheat sheet for working with sessions, windows, and panes. `NB` I have remapped the command prefix to `ctrl` + `a`.

Sessions

New Session

  • tmux new [-s name] [cmd] (:new) - new session

Switch Session

  • tmux ls (:ls) - list sessions
  • tmux switch [-t name] (:switch) - switches to an existing session

Latency numbers every programmer should know

L1 cache reference ......................... 0.5 ns
Branch mispredict ............................ 5 ns                     on recent CPU
L2 cache reference ........................... 7 ns                     14x L1 cache
Mutex lock/unlock ........................... 25 ns
Main memory reference ...................... 100 ns                     20x L2 cache, 200x L1 cache
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 4X memory
