  • If you’re just looking to get started with 3d modeling, it’s hard to beat Blender. At the cost of free, it’s by far the most affordable way to dip your toes in some modeling tools.

    For many workflows it’s world class. If you plan to do more organic forms or don’t need technical precision, then it’s very competitive or preferable to paid software.

    You might find it lacking if you plan to do parametric or technical CAD-style modeling. Even then, I think Blender can be a low cost way to learn what you want in your software before investing in more specialized software. You’ll learn enough of the modeling basics to more fluently navigate what other software provides.


  • Permissive licenses permit a broader range of use compared to “copyleft” licenses.

    “copyleft” here just being a cute way of being the opposite of copyright - instead of disallowing others from what they can do with “copyrighted” code, “copyleft” requires that they (upon request) share modifications to your code.

    Permissive takes away this requirement to share your modifications. “copyleft” is considered more free and open source (FOSS), permissive is more business friendly.



  • I’ve been there, but over the years I’ve gotten better at avoiding being in this situation.

    If you are implementing something for yourself, and merging it back upstream is just a bonus, then by all means jump straight to implementing.

    However, it’s emotionally draining to implement something and arrive at something you’re proud of only to have it ignored. So do that legwork upfront. File a feature request, open a discussion, join their dev chat - whatever it is, make sure what you want to do is valued and will be welcomed into the project before you start on it. They might even nudge you in a direction that you hadn’t considered before you started.

    Be a responsible dev and communicate before you do the work.



  • we need to know who makes the most green hydrogen

    That would be an awesome stat, but it’s not what the article claims. I explained that above.

    But because the topic has caught my interest I did some more digging. The only report I found was linked on Wikipedia, which says that 0.1% of all hydrogen globally is produced using renewable energy. This is the same figure China claims they produce, so by volume I would expect the total volume to be proportional to the production/consumption, which would mean China still would produce approximately 2x the next biggest producer. There could still be other countries punching way above their weight, but given the incredibly low net green production globally, we’d be splitting hairs over what amounts to research plant production. You’re welcome to continue searching for more specific reporting.

    Now, given that we’ve found ourselves on a tangent sparked by a misunderstanding of the article, trying to compare countries on a metric that amounts to 0.1% of production, I would say it would be a better use of both of our time to focus on how we get the other 99.9% of production over to green production. Given this article, China seems to be approaching that problem ambitiously and I’m glad to see it. To address climate change we absolutely need China to invest in green tech, so this article should only be received positively. I’m looking forward to tracking the progress, because it looks like there’s a lot of opportunity to improve globally.

  • It can both currently produce only 0.1% of hydrogen using a green process, while also developing a new process that is 99.9% green (for the hydrogren that it produces using the new process). That means the overall production right now is probably still ~0.1% green, but the point of the article seems to be that they hope to transition to this new process, which sounds pretty cool.

    And to also knock out a few other misunderstandings, I’ll also address your comment below: The stats you link are for the number of plants, not the volume of production or consumption (what is claimed). Both stats can be correct if China has large plants that produce more volume than in other countries. But better yet, we don’t even have to root around for the details - the article cites it’s source: the World Economic Forum’s latest whitepaper (June 27, 2023), which in turn cites statistica “Global Hydrogen Consumption By Country”. So there you have it - China out-consumes hydrogen at a rate of about 2-times that of the next largest consumer (the United States). That seems to track pretty well, since both countries are similarly developed, and China is about 4x the size of the US by population. If you wanted to split hairs, you could say that this doesn’t include volume of production. Given the incredible lead in consumption volume, I’m willing to grant them that omission.

    And, not chalking this up to you, but I’ve seen other replies in here about how China is somehow cooking the books. That’s becoming more and more obviously wrong (and more than a bit racist). As one indicator, their universities occupy 8 of the top 20 institutions in the Nature index. For those unaware, this is a premier British-based peer-reviewed journal that releases a ranking of academic institutions based on their publishing to high-impact journals. China’s year-over-year change also means that they’re rising on that list rapidly.
