PSQL

Magic words:

psql -U postgres

Some interesting flags (to see all, use -h or --help depending on your psql version):

• -E: will describe the underlaying queries of the \ commands (cool for learning!)
• -l: psql will list all databases and then exit (useful if the user you connect with doesn't has a default database, like at AWS RDS)

Requirements

• no upfront installation/agents on remote/slave machines - ssh should be enough
• application components should use third-party software, e.g. HDFS, Spark's cluster, deployed separately
• configuration templating
• environment requires/asserts, i.e. we need a JVM in a given version before doing deployment
• deployment process run from Jenkins

Solution

hosackm

from flask import Flask, Response

app = Flask(__name__)


@app.route("/wav")
def streamwav():
    def generate():
        with open("signals/song.wav", "rb") as fwav:
            data = fwav.read(1024)

Gracefully Deprecating TLS 1.0

TL;DR: I explain how to detect TLS 1.0 connections and, by way of custom headers, warn the user about the coming change to more modern TLS versions.

1. Background
2. How you can prepare

• Nginx
• Apache
• f5
• HAProxy
