Jaccard coefficient between two boolean NumPy arrays or array-like data. This is commonly used as a set similarity metric, and it is a true metric. The dimensionality of the input is completely arbitrary, but `im1.shape` and `im2.shape` much be equal. This Gist is licensed under the modified BSD license, otherwise known as the 3-clause BSD.

How to setup your own CA with OpenSSL

How to setup your own CA with OpenSSL

For educational reasons I've decided to create my own CA. Here is what I learned.

First things first

Lets get some context first.

Keep retrying SSH connection until success (Useful for waiting for VMs to boot)
#!/usr/bin/env bash
# Check we've got command line arguments
if [ -z "$*" ] ; then
echo "Need to specify ssh options"
exit 1
fi
# Start trying and retrying

psycopg2 Cheatsheet

Connect and Select

connect()

The shortest connect:

from psycopg2 import connect
psql_conn = connect("dbname=XXX user=XXX password=XXX host=localhost sslmode=require")
psql_conn.close()

Self Signed Certificate with Custom Root CA

Create Root CA (Done once)

Create Root Key

Attention: this is the key used to sign the certificate requests, anyone holding this can sign certificates on your behalf. So keep it in a safe place!

openssl genrsa -des3 -out rootCA.key 4096
