Hey-yo
Hope you all had a lovely weekend.
Came across this pretty cool open source platform as a service. Definitely going to be exploring it as an option for setting up all of my personal projects. Kind of tired of doing the whole nginx/Docker config thing for each new app. This description "From localhost to .com in seconds" sold me in seconds.
Also just for reference, if I feature an article in the newsletter, that doesn't necessarily mean I agree with its contents. I feature things I think are interesting, which can sometimes be things I disagree with. I don't think it's wise to live in an echo chamber of your own ideals and opinions, and this newsletter is a reflection of that.
Anyway, here's the issue.

The Origins of Python

Published: 25 November 2022
Tags: history, python

Lambert Meertens goes back in time to describe the history of Python, while also touching on previously existing languages and language design in general.
Some highlights:

  • "The ability to evolve and adapt to changing needs is an essential attribute for the long-term survival of any programming language"
  • Python's success can be attributed to its simplicity and ease of learning
  • Python was inspired by ABC

A gentle introduction to Domain Driven Design

The Lone Architect discusses the different steps that can be taken to move from a simple transaction script to a more complex domain-model code. The author starts with Active Records, which abstract away the database implementation details, and then moves to a service that encapsulates domain logic. This results in less duplication and more readability.
Some highlights:

  • Domain driven design (DDD), roughly speaking, is splitting up code based on what category of business function it falls under
  • It's not a fix all methodology; don't over complicate solutions to simple problems
  • There are different degrees at which DDD can be applied

Database optimisation, analytics and burnout

Published: 22 November 2022
Tags: data, data processing, database, distributed systems, python

Mark Veidemanis explains his work on Pathogen, a data analytics pipeline. Mark also mentions Sandstorm, which is a cool open source platform for self-hosting utility apps.
Some highlights:

  • Concurrency and threads are hard
  • Finding the correct tool/library is hard
  • "There's always another millisecond to shave off the execution time, but how long are you going to spend doing it?"
