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

How to set up git to use the GPG Suite

GPG and git on macOS

Setup

No need for homebrew or anything like that. Works with https://www.git-tower.com and the command line.

  1. Install https://gpgtools.org -- I'd suggest to do a customized install and deselect GPGMail.
  2. Create or import a key -- see below for https://keybase.io
  3. Run gpg --list-secret-keys and look for sec, use the key ID for the next step
  4. Configure git to use GPG -- replace the key with the one from gpg --list-secret-keys

Use neovim as diff tool
[merge]
tool = vimdiff
[mergetool]
prompt = true
[mergetool "vimdiff"]
cmd = nvim -d $LOCAL $REMOTE $MERGED -c '$wincmd w' -c 'wincmd J'
[difftool]
prompt = false
[diff]
