  • It’s about hype and economics.
    Tech companies can theoretically scale well and are valued on the expectation of growth while normal companies are manly valued based on what they currently do. An app can basically be copied for free to millions of users once it has been coded and servers don’t cost that much. A traditional company, say a car company, that wants to increase profits has to build a new factory or something. The problems arise when a companies perception goes from startup/tech company to normal company.

    Example: wework was a startup that rented office space long term and lets it customers rent short term from them. Once people realized, that it was a real estate company and not a tech company it’s value plummeted, it couldn’t raise more capital and went bankrupt.

    Edit: spelling








  • How?

    Good question. I said should, not could… it would take a constitutional change, […]

    I mean: if you had the power, how would you ban parties? At what point do political organizations become parties? How about individual representatives working together?

    Bring back the old literacy tests while you’re at it

    Pfft. The two are not the same. You could be perfectly illiterate and still find out what the supposed values of the politicians were by simply listening to them, or just talking to others about policy and politicians ties to them, like we used to.

    Yes literacy is not the deciding factor, but it was always a pretense to keep certain people from voting.

    Imagine how much more attention you would have yo pay if you had to understand who to vote for.

    How much time should a person spend following politics to get enough of an understanding? What about poor people working long hours with little free time?
    Guess I should have gone with the landowning requirement instead.

    The Hatch Act applies to all career federal civil servants and prevents anyone under that designation from running from office in any partisan race. Meaning if your local government doesn’t allow political affiliations to be listed, then you

    Sound like a problem with the Hatch Act, not with political parties. Over here civil servant can run in political races as long they separate their work and political live, they are not allowed to wear uniforms at political events for example.


  • Short answer:
    It gave us compiler explorer, now that it has served its purpose we should stop doing it.

    Long answer:

    Why does hft even exist?

    Hft can exist because most stock markets react to requests as fast as possible and have no noticable fees for certain use cases. This means algorithms that do simple trades like if goggle goes up, buy other tech companies or buy any stock that goes up in europe on the NY market can make small profits if they are faster than everyone else.

    Does it have any value?

    There is one exchange that imposes a delay on every request, effectively inhibiting hft, and its opening actually improved market conditions on all exchanges. This implies it has negative value.
    They also spend millions on hardware, tools and developers to skim small sums of many transaction on the stock market. They are effectively a (very inefficient) tax on the stock market that goes to improving C++ compilers and funding hardware startups.







  • The new version seems to fix that since your comment was written, but it will stil panics if less than 2 samples are provided, unless the crate it wraps panics at an earlier point.

    let peak = buf
                .iter()
                .copied()
                .enumerate()
                .take(self.sample_count / 2)
                .max_by_key(|(_, s)| (s.abs() * 1000.0) as u32)
                .expect("to have at least 1 sample");
