    I am not particularly keen on the app idea for reasons similar to what others presented, but I was wondering if you would talk, either here or in a separate post, about your process for getting a landing page up so quickly. My own experience with web development has mostly been one of plodding confusion, so learning how people move quickly would be neat!

    In a completely different style, there is also Northwest Passage, which has several different versions. I am partial to Stan Rogers but there is apparently a metal version that I liked better than I thought I would.

    I have tried that, and I think I will probably try to do it that way if I use Nim for anything bigger. For small stuff like on Exercism though, I think it's overkill, and it's nice to be able to do data.moduleFun instead of module.moduleFun(data).

    There is a lot of nice syntax in there, but there are definitely some things that they do in favor of simplicity that bother me. The one I can think of off the top of my head is that when you import code from another module, everything just gets lumped into one namespace by default. It's probably not a huge problem, but it was jarring coming from previous Python use.

    I've got two things going on. First is that I am dipping my toes into Nim using a platform called Exercism. I don't think it's likely to have significance for me outside of hobby projects but I like learning new and interesting languages, and I like bite size programming problems, so this seems like a good way to do both.

    Second is that I have decided to help contributing to Tildes! I just put up a merge request for my first issue, hopefully the first of many.

    I'm not totally sure how you are getting the cost numbers, since I think the AUD is weaker than the USD, so by straight currency conversion it should be about $26,500 USD. Then again, shipping from Australia (or wherever they are made) as well as any tariffs and other costs would probably bring it up for the US and EU markets. It is also a comparison between a mature, scaled technology against something newer and yet to scale. Their pre order for 2022 onward already drops in price to $29,450 AUD, so that's a plus.

    Pricing aside, what I really don't understand is why they've chosen home energy storage as the strategy here. Based on the sized of those hydrogen packs and the overall size of the unit, it seems like this tech would be purpose made for vehicles, where you can rely on fueling infrastructure to eat the 50% loss and have the electrolyzer, and you just need dense hydrogen storage. Hacking some measurements out of their images, each of those hydrogen storage cells looks to be ~110mm by ~280 mm by ~400 mm and 10 kWh is 36 MJ, so those cells store about 3 MJ per liter volume, which is already better than the best lithium batteries that Wikipedia knows of at 2.43 MJ/L. I wonder if they were worried about how people are always skeeved by hydrogen in vehicles for some reason, or maybe the vast majority of the cost there is tied up in the metal they use for those cells so going bigger looks worse? Either way, I'd love to know their rationale for this application and not automobiles.

    I recently watched this youtube video highlighting the potential of this company's hydrogen storage technology. I think it is an interesting concept despite a lower round trip efficiency compared to Lithium batteries (~50% vs ~95%). They also appear to be happy to take international pre orders. Do people here think this is a promising technology? Would you consider purchasing one for your own home?

    Overdrive books have DRM, though, so I'm not sure how much of a difference there is on the IP protection front. If people can crack that, then they can crack Amazon's and it's a bit moot.

    That speech is one of the things that gives me great respect for Eisenhower and the political climate after the Second World War. Personally my favorite part of the speech is this:

    The fruit of success in all these tasks would present the world with the greatest task—and the greatest opportunity—of all. It is this: the dedication of the energies, the resources, and the imaginations of all peaceful nations to a new kind of war. This would be a declared, total war, not upon any human enemy, but upon the brute forces of poverty and need.

    I thought the same, not because of what the robots are doing but because of the lighting. I think the lighting is just exceptionally even, which lends it to looking a bit like a render.
