Git pre-commit check to stop accidental commits to master/main/develop branches.
#!/bin/bash
# This gist contains pre-commit hooks to prevent you from commiting bad code or to the wrong branch.
# There are six variants that I have built:
# - pre-commit: stops commits to master/main/develop branches.
# - pre-commit-2: also includes a core.whitespace check.
# - pre-commit-3: the core.whitespace check and an EOF-newline-check.
# - pre-commit-4: only the core.whitespace check.
# - pre-commit-5: elixir formatting check.
# - pre-commit-6: prettier formatting check.
# Set the desired version like this before proceeding:

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

Add a help target to a Makefile that will allow all targets to be self documenting
# Add the following 'help' target to your Makefile
# And add help text after each target name starting with '\#\#'
help: ## Show this help.
@fgrep -h "##" $(MAKEFILE_LIST) | fgrep -v fgrep | sed -e 's/\\$$//' | sed -e 's/##//'
# Everything below is an example
target00: ## This message will show up when typing 'make help'
@echo does nothing

git push origin :refs/tags/12345

I couldn't find a quick example of how to deploy a node.js app using Capistrano 3. This gist assumes you are using Capistrano 3, Upstart, Forever, ssh/forward agent, and an unprivileged user named 'deploy'. Hopefully this simple setup will help to get you started.
# config/deploy.rb
# probably a lot of ways to improve this...
set :application, 'my_app'
set :repo_url, 'git@github.com:USERNAME/my_app.git'
# should set up a deploy user
set :user, 'deploy'
set :deploy_to, '/var/www/my_app'
set :scm, :git

Steps to install a Comodo PositiveSSL certificate with Nginx.

Setting up a SSL Cert from Comodo

I use Namecheap.com as a registrar, and they resale SSL Certs from a number of other companies, including Comodo.

These are the steps I went through to set up an SSL cert.

Purchase the cert

Simple Plugin for "Uptime" that send alerts via Pushover. I am not a Node hacker ... I barely understand why this code works .... but it does. I have not tried it with multiple users yet, so dont know if it will work to do multiple notifications. Let me know if you try it.
/**
* Pushover plugin for the uptime project - https://github.com/fzaninotto/uptime
* Thanks to DMathieu for the Campfire plugin which I basically hacked up to make this
* work: https://gist.github.com/dmathieu/5592418
*
* This index.js files goes to a directory `plugins/pushover` in your installation of uptime.
*
* Notifies all events (up, down, paused, restarted) to pushover
*
* This plugin has a dependency on `pushover-notifications`.
