Python 3.9 Released: What’s New — Unlike its sister languages like Perl and Ruby, Python has, in spite of a slightly rocky 2.x to 3.x transition, found a way to stay relevant and continue to grow at a rapid pace. 3.9 is an evolutionary rather than revolutionary release and packed with good tidbits.

DigitalOcean Wants to Redefine PaaS with New 'App Platform' — A take on ‘reimagining’ Heroku-style PaaS (platform as a service). The idea is you point App Platform to a repo and they deploy it on their hardware. Supports Python, Node, Go, PHP, Ruby, and static sites out of the box, but Docker can also be used. Seems a wise move for DO as many developers continue to move away from wanting ‘boxes’ to more 'managed' deployments.

How Hacktoberfest is Hurting Open Source — Hacktoberfest is a program (from DigitalOcean) run entirely in good faith but the promise of a t-shirt in return for sending pull requests to open source repos has caused lots of spam in the form of terrible commits. There are lots of causes including a popular YouTuber promoting the idea of making such commits, but there’s good news! Hacktoberfest is becoming an opt-in event so repos have to express an interest before they qualify and 30k+ repos already have 👍
