  • This is my valley rhetoric – I’m just getting warmed up! My friend, have you not heard? Substance is subjective! Perhaps your definition has been clouded by the fog of your own high-mindedness. I prefer to dive into the chaos of the debate – a dance of wit, if you will. I thrive in the ebb and flow, where traditional rules bend, and creativity reigns. Your rigid structure is no competition for my unpredictable flair! Unpredictable flair or just chaotic noise? There’s a fine line between artistry and a cacophony of confusion, and I fear you’ve leapt over it with reckless abandon. True mastery lies in the ability to convey ideas clearly and convincingly, not just in throwing around clever phrases like confetti. But keep at it; your enthusiasm is noted, even if the execution leaves much to be desired.







  • My real issue with Python comes with managing a development environment when multiple developers are working on it. Dependency management in Python is a headache, and while in theory, virtual envs should help with synchronizing environments from machine to machine, I still find it endlessly fiddly with a bunch of things that can go wrong that are hard to diagnose.

    Late to the party, but a serious suggestion; give uv for Python dev env/package management and ruff (or Black, for that matter, if you’re not using a formatter yet like some others here in the comments) for linting/formatting a shot.

    They’re great and feel magical to use if you’ve known the pain experience of not having them.









  • TL;DR: Depends on what you mean.

    Long version:

    Disclaimer: I’m not an expert by any means, I haven’t vetted the links properly (or at all), they’re mostly there for illustration and if you want to read further. Also, the last time I actually read up on this is quite some years ago, so stuff may have changed in the industry and/or my memory on specifics is foggy. Many of the links lead to Tesla sources since I first looked into this topic back before Musk made it known to the public that he’s an insufferable human being.

    Batteries are usually structurally integrated into the chassis with modern EVs, since that means space (and often small weight) savings, and is easier/faster to do in manufacturing.

    With that knowledge, it is safe to assume that replacing a car’s battery is a difficult or next to impossible task, outside of end-of-life reuse.

    But this is actually where it gets interesting, since EV batteries last many years anyways: What happens when the car’s time has come?

    Well… the batteries can be reused. It’s not a trivial process, there’s several ways to do it, but the best intuitive explanation I’ve found is this: In raw ore, lithium and other metals are present at maybe 0.1 or 1%, per tonne of material. In batteries, it’s maybe 99% of reusable, expensive material. Even if you let it be 90 due to inefficiencies in recovery, or whatever, it’ll still make way more sense financially to work with old batteries – once you have the process figured out and automated machinery to get it done in place.

    All that is assuming total destruction of the existing cells, which, depending on their state, may not even be necessary at all. In fact, it looks like all of that may not be needed for as much as >80% of batteries. Wow!

    And we all know the best way to ensure companies are doing something is if the financial aspect aligns with their goals. It’s in their best self-interest to be able to and actually do this.

    So: Replaceability per car – eh, doesn’t look to great. Replaceability across the industry? Perfect.
