xcsrz / create-ssl-cert.sh

Last active October 28, 2015 23:19

This script creates the .key and .csr files using the bare minimum information. It's only argument is the domain name to be secured. Prepend "*." for wildcard domain certificates. Customize the DEFAULT_ORGNAME and DEFAULT_ORGCOUNTRY setting variables at the top before use. Environment variable overrides are ORGNAME and ORGCOUNTRY.

	#!/bin/bash

	DEFAULT_ORGNAME="xcsrz"
	DEFAULT_ORGCOUNTRY="US"

	if [ -t $1 ]; then
	echo "you must provide a domain name (don't forget the asterisk if it's for a wildcard certificate"
	echo ""
	echo "Usage:"
	echo " ${0} DOMAIN"

xcsrz / WriteChanCloser.go

Created January 5, 2017 17:42

Modeled after Golang's ioutil package's NopCloser method which wraps an io.Reader interface in an io.ReadCloser facade interface, this code takes an io.Writer and a nil channel and returns an io.WriteCloser interface. The example.go file demonstrates usage in an http.HandleFunc as a very over complicated counter using the worker-and-channel-over…

	package main

	import "io"

	type writeChanCloser struct {
	io.Writer
	closeChan chan struct{}
	}

	func (wcc writeChanCloser) Close() error {

xcsrz / center_text_on_image.py

Created March 8, 2017 00:17

Center text on an image with Python and OpenCV. Had to come up with it myself as no one was spelling this out anywhere (or google couldn't find it)

	#!/usr/bin/env python

	import numpy as np
	import cv2
	from time import sleep

	# create blank image - y, x
	img = np.zeros((600, 1000, 3), np.uint8)

	# setup text

xcsrz / sendgrid_keys.rb

Created December 7, 2018 22:47

Sendgrid's UI does not give you full control over API keys. This script does. Set two environment variables and you can view your keys, their scopes and add/remove scopes from any key. Simple utility but saves a lot of time and headache.

	#!/usr/bin/env ruby

	require 'base64'
	require 'rest-client'
	require 'json'

	# https://stackoverflow.com/questions/38613941/sendgrid-error-access-forbidden-when-trying-to-get-user-profile-api
	$base_endpiont = "https://api.sendgrid.com/v3/api_keys"

xcsrz / clean-browser-session.sh

Created March 28, 2019 18:54

Run chrome completely separate from the standard as though it has never been run before on that computer, but skip the welcome wizard stuff.

	#!/bin/bash

	app="/Applications/Google Chrome.app"

	dir=$(mktemp -d)
	# echo $dir
	touch "${dir}/First Run"
	mkdir "${dir}/Default"
	echo '{"browser":{"has_seen_welcome_page":true}}' > "${dir}/Default/Preferences"
	exec "${app}/Contents/MacOS/Google Chrome" --bwsi --disable-signin-promo --bypass-app-banner-engagement-checks --no-managed-user-acknowledgment-check -no-first-run --user-data-dir=${dir} --system-developer-mode
