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

Environment variables in Jekyll templates

This is one way to pass some data (API tokens, etc.) to your Jekyll templates without putting it in your _config.yml file (which is likely to be committed in your GitHub repository).

Copy the environment_variables.rb plugin to your _plugins folder, and add any environment variable you wish to have available on the site.config object.

In a Liquid template, that information will be available through the site object. For example, _layouts/default.html could contain:

lttlrck

git branch -m old_branch new_branch         # Rename branch locally    
git push origin :old_branch                 # Delete the old branch    
git push --set-upstream origin new_branch   # Push the new branch, set local branch to track the new remote

WTF Flow

[Flow][] static type checker is a wonderful attempt to bring [algebric data types][] to JS. It is still fairly new project and there for has few WTFs that can pull you down the rabbit hole. This document is attempt to document things that may seem like a WTF from the perspective of JS developer who tries to employ static type checker, or in other words, some items on the list may be very subjective & based on the background of the writer.

Polymorphic type that is a function

It is very likely that one will wind up using [Polymorphic functions][] to solve a more general problem. And if you define type alias for such a function you may be puzzled what is the right syntax should be used for such type definition.

Let's start with:

IgnoredAmbience

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE fontconfig SYSTEM "fonts.dtd">
<!--
Noto Mono + Color Emoji Font Configuration.

Currently the only Terminal Emulator I'm aware that supports colour fonts is Konsole.

Usage:
0. Ensure that the Noto fonts are installed on your machine.
1. Install this file to ~/.config/fontconfig/conf.d/99-noto-mono-color-emoji.conf
