Optimizing Python Code Using Cython: A Beginner’s Introduction

There are much better resources than this blog that will lead you down the rabbit hole of Cythonizing your Python code, but this is just a very easy introduction, outlining my own personal experiments as a Cython beginner, myself. In this tutorial, we will use my dictionary creation tool, brutalist, as a really bad example of how to Cythonize some Python code.

HSTS – The Missing Summary

HSTS (HTTP Strict Transport Security) is a feature supported by all major browsers, and it’s a method for websites to declare that they should ONLY be accessed securely over HTTPS and never over an unencrypted HTTP connection. If a site has an HSTS policy, browsers will refuse all insecure connections to that site AND prevent users from accepting insecure SSL certificates.

HTTP/2 – The Missing Summary

We know our browsers support it, and we know AWS, Akamai, and other big players support it within their infrastructure already…but do your applications and/or on-prem infrastructure have what it takes to leverage the awesomeness that is HTTP/2?

Think about it. We went from HTTP/0.9, to HTTP/1.0, to HTTP/1.1…to a full version upgrade of HTTP/2. That alone should tell you that there are some very interesting features lurking underneath the hood. This is the missing in-depth summary that you have been missing while being overloaded with too much information reading official specs and getting lost in sensory-overload-causing diagrams. Welcome to HTTP/2 – the missing summary.

Highly-Available, Scalable WordPress using ECS/Docker & RDS/MariaDB

The recent Amazon S3 outage showed us just how delicate the state of the web is, especially when you don’t utilize Amazon’s built-in redundancy features. My goal was to create a highly-available and scalable WordPress installation in AWS using Docker. I would have auto-scale Docker clusters in multiple Availability Zones running Nginx, PHP-FPM, and a Redis client. The Docker config and WordPress install would be on EFS volumes that would be
mounted in the Docker containers. I would use an RDS MariaDB for the database backend and Redis-based ElastiCache for serving up the site blazing fast from memory.
