  • Tariffs and moving away from free trade makes us all poorer. We need EVs to be cheap and abundant now more than ever. People complain it’s “uncompetitive” when china subsidizes the shit out of their EV industry, but the US did the exact same thing with “build back better”, and the EU got pissed about it. Just as the US has been doing for decades with agriculture and the defense industry.

    I agree subsidies are contrary to the best methods of free trade but until we can force countries to stop (and stop doing it ourselves), they are a part of life. Let china win the EV race, we all get cheap abundant EVs, and America can win the space race and we’ll all get cheap satellite services, and Europe can win idk whatever it is they’re working on over there and we’ll all get a bunch of cheap copies of that.

  • Wait till you find out about some of the nazis etc who have contributed to the linux kernel. One guy even murdered his wife! And Linus himself is… well let’s just say some of his behavior is “problematic”. Oh and Richard Stallman my lord. Lemmy/AP has some interesting people as well. Nostr is an open protocol worked on by dozens of people. I would also question the motives of a “journalist” who makes it their business to dox anonymous developers, especially people developing software that could get them imprisoned in certain countries.

  • Or because they’re just genuinely well received by the public. One of my reps has been in public service for decades and I actually like most of his positions. The longer you are in office, in theory, the better you will understand the legislative system and be able to push issues your constituents want. If you do, you keep getting re-elected, if you don’t, you don’t.

    Regardless, this is a problem of FPTP and the primary system not age. Primaries select for who is considered the “most electable” not the candidate “most want”. Fix that system, and age is not an issue. Or if more people who don’t like 80 year olds participated in the primaries this would also be less of an issue. But they don’t, they just complain about the “lesser of two evils” choice even though they had a “lesser of 10 evils choice” and chose not to participate in it.

  • Disagree with this one, voters should have the final say in who is electable. If there’s an 85 year old out there who can convince 51% of the electorate to vote for them in the primaries, go for it. This rule will become a problem if life expectancy continues to increase at the rate it has the past 50 years, with AI and some major changes in genetics, we are poised to solve a lot of causes of death in our lifetime, which means longer life expectancy.

  • Programming. Challenging and creative in a way that is different than art & music but still somehow similar. I find it almost relaxing sometimes. Python is a great first language and you can go from no knowledge whatsoever to a working program that does something genuinely useful in an hour, like scraping a website and showing you some data from it. Mastery takes years.

    If you genuinely enjoy programming, you can legitimately change the world with your knowledge. There are tons of open source projects out there which benefit humanity yet don’t have enough development talent. It’s one thing to volunteer your time and see a good outcome from it, it’s another to volunteer your time to build a system which guarantees good outcomes for many people over long time periods and get to see that system grow and get used by people.

  • There are two factors at play here which have to meet in the middle: where is the most efficient place to produce the product and what is the most efficient way to ship the product? The answer to the first question is: wherever has local access to the resources (people, iron ore, etc) and energy required and has the scale required to efficiently build those products. The more cars your country produces, the bigger your factories are going to be, and the more efficiently you can make cars. The answer to the second is by sea. Always by sea. Boats are vastly more efficient than rail, truck, anything.

    Container ships are reallyyyy big and reallyyy slow so they experience relatively low drag

    Drag on a plane is high, they have two massive jet engines that try to push them through the air burning literal tons of fuel to do so. Obviously not the best if you want to be efficient.

    Drag on a train scales with the weight of the train. A long heavy train will have more rolling resistance that sucks away energy from it. You can’t scale this down without going through and making your wheels harder so they deform less, but you already have steel wheels on steel rails so you’re not going to get much better.

    Drag on a ship scales with the surface area of the ship that is touching the water, putting more weight on a ship causes a bit more of the surface to touch the water, but not very much. Moving an empty ship is going to use a surprisingly large amount of fuel because the drag is pretty similar, but your fuel consumption isn’t going to go up linearly with load like it would for a train.

    Consider something like a Maersk Triple E, it carries over 18,000 20 foot containers. It can get them up to 23 knots (26 mph) but generally runs at 16 knots for efficiency and does this with just 80,000 HP of engine capacity. Those 18,000 containers would turn into a train 68 miles long! With 140,000 tons available for cargo, that’s just 0.57 HP/ton at full speed, and significantly less at the lower cruising speed(where the ship is built to be efficient). Trains will generally run around 1 HP/ton so this big ass cargo ship is using half to a third as much power to move its cargo.

    The downside of this is that it takes 6-8 weeks for a ship to go from China to California, but the upside is that it did that with a crew of just 13 and just had a big diesel running in its happy spot the whole time.

  • So let them compete, isn’t that the idea? Countries and economies can compete with each other just like companies do. China can subsidize their EVs, America can subsidize its defense industry and corn, Europe can subsidize cheese and wine or whatever it is they make, each country specializes and offers the best product at the cheapest prices for consumers. Or make WTO have more ‘stick’ and less carrot so we can make countries stop subsidizing their own industries.

    Either way, a return to trade tariffs and isolationism doesn’t sound great to me. It sounds like everything getting more expensive and less efficient (and therefore, more environmentally wasteful). It also sounds like countries being less dependent on each other, which means less reason to not go to war. We live in a very rare, peaceful time in human history. International trade (and massive technological/scientific breakthroughs) are a major part of that.

  • Millions for development? Do you have any sources? I’d like to read about it. Thanks

    Watching videos from the most recent Bitcoin conference is a good way to get updated on recent development changes to the protocol, lightning included. Bitcoin Magazine if you prefer reading to watching. Github if you prefer reading code to words.

    I don’t have a specific source to cite here, just am generally aware of what’s going on in the bitcoin space. Lightning labs is the main company building the protocol, they’ve raised 86 million in funding, though not this year. There’s dozens of lightning wallets, some of which are supported/published by companies like ACINQ whose investment capital measures in the tens of millions. Tons of stuff is being built on it. And more payment providers are integrating lightning: Strike and Cash App are the two major ones. Coinbase recently announced they will be adding support for it, Kraken and most other exchanges already support it. There’s a lot of FUD about lightning, there are some valid critiques to be made for it as a “universal scaling strategy”, but generally speaking, it works well and does what it’s supposed to and has plenty of room to scale. There are proposals (channel factories etc) which will massively help with scaling as well.

    Likely there will be more than one L2 in the future to optimize for different use cases. But for large orgs who frequently need to move liquidity around, solutions like lightning are excellent. They can settle their accounts with other orgs and their customers instantly. Think banks, online retailers, online marketplaces, etc. This leaves less money “in flight” and at risk. And it can also be used for micro-transactions for everyday people. A bunch of funding just got allocated to Ark as well, which is another L2 solution similar to but different from lightning. Fedimint is another project/proposal to look at if you are researching all this.
