  1. Use your local library?

    I’m amazed to see so many comments focused on everything but libraries.

  2. I regularly use soulseek to download archival copies of music that I pay for. The artist makes their money, and I don’t have to worry about my account access.

    Soulseek is brilliant.

  3. as is the consequent traffic, pollution and inefficiency that choices like yours add up to.
  4. i take it you are not from the old world? Only in north america will you find dense cities without small, normal grocery stores.

    These are incredibly common in all of the old world.

  5. are you familiar with population distributions and the fact that more of the word lives in urban areas than rural?

    >So everyone drives

    Citation needed, because this is obviously false.

    >Or if they're too poor to afford a car then they just don't go anywhere

    What a horrible thing to say.

  6. most people in the US are forced to drive, they don't willingly choose to sink large sums of money into a rolling metal cage.
  7. "we" here is a minority of the population in any developed country. The vast majority of people - almost globally - live in dense areas.
  8. cars are barely efficient in terms of time. In cost terms, cars are incredibly expensive once you add in infrastructure costs, insurance, fuel, the cost of land use, etc.

    Public transit is efficient even outside areas of high density - see suburban Europe or India. Why are so many people here utterly car-brained?

  9. Think about what was lost in the quest for dark mode versus the benefits.

    I would argue that menu icons are more useful than dark mode in several situations.

  10. India's rail network is not fully electrified, this is false. Even the most popular broad gauge network is not fully electrified. Diesel trains are still very common. Remember also that the Indian government is very skilled at manipulating data without actually delivering results. Just look at the lies they spewed during the pandemic about deaths.

    India's promised ascendance to power and influence remain perpetually a few decades away. Meanwhile, the poor continue to lose purchasing power, the rich exploit the entire country, and India's total economic exports are comparable to those of the Netherlands.

  11. the #1 problem with the EU's administrative structure is that its power comes from below, i.e. from the member states. Any of them could pull a Brexit and the entire union could be in jeopardy.

    The #2 problem is language. Despite what many on HN think, European borders very much exist. They exist via language and bureaucracy.

    These two combine to create many problems the EU and Europe in general has. The lack of vision, the excruciatingly slow bureaucracy, both are symptoms of the same underlying problems.

  12. i wonder if the incessant marketing from US auto companies had anything to do with this "desire". Why invest in more efficient engines, at lower profit margins, when you can convince your customers that their obese vehicles are all the protection they need.

    There are very few countries where pedestrial fatalities have continued to rise, and the US and Canada are two of them, driven in large part by auto obesity.

    You point to popularity, but I will mention that it is impossible to buy a sedan from US automakers today. The reason why is simple - profit. Larger cars are more profitable. When combined with incessant marketing that a pickup truck makes you more "manly", you can manufacture "desire" and "preference".

  13. yes, what is "normal" has been redefined to align with what is more profitable for the US auto companies. There is no real reason why most US drivers suddenly switched from sedans to large SUVs and bloody pickup trucks in the past 40 years. Except for profit.
  14. this is also my understanding. The range is large because it caters to passenger cars, lorries and construction equipment. Construction equipment is seen are more rugged (it often is) and this is now projected as a desirable trait for SUVs and pickup trucks.

    The irony is that SUVs and pickup trucks do not need lights 137 cm above ground, but that height is perfectly legal in too many countries. These vehicles are a menace and should be legislated out of existence.

  15. you weren't in a short car, you were in a normal car. Society really needs legislation around auto obesity. Cars are too big, too high, too heavy, all at despite being less practical than a station wagon from twenty years back.
  16. this is a racist dog whistle. Stop with the "mass immigration" BS.

    India, contrary to what the racists believe, has a long and successful vaccination program. A country of 1.5 billion people has around a 70% MMR vaccination rate among infants. Canada's in the 80% range and dropping.

  17. all true, but in the vast majority of electricity markets, inertia is not priced.

    what does drive the price of electricity is fuel cost, not grid stability.

    Solar inverters do not have physical inertia but they can have fast frequency response via capacitors. Many wind turbines have this feature and at scale, it is a decent replacement for electromagnetic inertia.

  18. This has almost nothing to do with how electricity is priced.
  19. comments like this really show that many people with strong opinions do not understand how the electricity grid, electricity markets or electricity economics work.

    Electricity is priced at the edge entirely because demand must match supply at all times. You either meet all electric demand or someone will go without power. This is why marginal pricing exists and this is why the most expensive generator is always the last to be accepted. This is why electricity at night is cheaper that during the day.

    Please, if you do not understand what you are talking about, it's ok to just say that you don't know. Don't spread misinformation like this.

  20. you heard wrong. What most electricity grids forbid is exporting power from your home to the grid when the grid is down. The claimed danger is that energised power lines will kill people working on the lines.

    The reality is that the vast majority of home inverters (in an EV, battery or solar PV) is nowhere near powerful enough to energise even a single distribution transformer.

    This is yet another example of electricity codes being unrealistically restrictive.

    Generally, there's nothing stopping you from disconnecting your home from the grid during a power outage and running your own devices off a battery. Going fully off-grid depends on your local laws.
