... but that's actually a good thing

I've already written a ton about subinterpreters since a year ago:

• How good are sub-interpreters in Python now?
• Python 3.14: State of free threading
• Subinterpreters and Asyncio

Recently I had some time to dig a bit deeper into subinterpreters and check my understanding …

As we approach the holiday seasons, we get to "enjoy" another 12 days of Advent of Code. Every year I try to do something a little different, last year I had a lot of fun solving it in Ocaml, prior years I've tried the latest Python features. This year I've …

So I've just released a package called lazy-helper. This comes as lazy loading has been a hot topic once again due to the proposal PEP-810.

Using my package we can define lazy loaded dependencies nicely:

Coincidentally Brian Okken has recently written a blog post covering the topic of lazy loading …

Python 3.14 was officially released on October 7th. There are a lot of new features and I've covered some of them before in:

• Python 3.14: 3 smaller features
• t-strings: the good and the ugly
• Subinterpreters and Asyncio

Mojo has been on my radar for a while. In fact, I heard about it on launch back in May 2023. It was touted as a super set of Python with 10000s of times the performance. It's main focus is on AI related workloads with strong built in support of …

It's been just over a year since I started my blog. In fact, this is my 27th blog post. I thought it'd be a good time for me to share some insights on blogging.

Motivation

Recently I've been asked by some people on why I do this. I think for …

Previously when discussing asyncio backpressure I've made some claims that were not necessarily complete.

I said:

It works well for 100s of urls but when we hit a big number like 10000s we have a problem.

The program seemingly hangs. This is because all the tasks are being created first …

The python packaging landscape and developer experience has shifted dramatically in the past year or so with uv's launch marked a pivotal moment. But behind the scenes many PEPs have worked to get us to this point.

One such PEP was PEP 723 – Inline script metadata which we discussed …

Feature flags or dynamic configuration is something that I find very useful, however I've never had the chance to use them. This is for a lack of options launchdarkly, flagsmith and unleash to name a few.

SaaS options can be amazing with a full array of features, but I would …

PEP-734 subinterpreters in the stdlib has officially been included in the Python 3.14 as a very late addition. subinterpreters now has a new home in the standard library module called concurrent.interpreters.

If you've been following my blog posts you'll know that I'm particularly excited about this feature.
