  • It adds liquidity and that does more good than bad for everyone, whether you’re a retail investor looking to enter or exit a position without facing a hefty ‘tax’ from a wide bid-ask spread, or you’re managing an ETF and need to dump 300k shares of something while rebalancing.

    Without HFT a lot of tickers would look like options and futures contracts - no volume, wide spreads, and rife with abuse from people walking orders up and down



  • “All-cause mortality” simply means death from all (or any) causes.

    So for smokers, you got a buttload of people with this thing in common, and rather than look specifically at something like deaths from lung cancer, you take a step back and look at deaths from anything. And then go in and try to find correlations and help to understand those correlations.

    It’s kind of a chicken and egg scenario, because some of those causes might not be from smoking, but from a person’s proclivity to smoke.

    For example, smokers might possibly be more impulsive than non-smokers (generally speaking) and there might be a higher risk of motor vehicle fatalities in the smoker group, but the cause wouldn’t be smoking, it’d be underlying behavioral differences that would make someone more likely to smoke.

    It’s basically looking at mortality from a distance as opposed to looking at very specific things up close (but with the data it lets people zoom in on everything)




  • With Lemmy you can make an account on one instance and set default sort to the top posts for the past hour, make an account on a different instance and set default sort on that account to top posts in the last 12 hours or Hot or whatever, bookmark them both, and have a neverending stream of new content.

    People already noted other reasons that I agree with but my current setup being 2 accounts with default sort set up like that, I vastly prefer this to Reddit’s layout

    With a 10% rate of return money doubles every 7 years, rule of 72. With wages being pretty damn flat eventually people won’t be able to afford things on income but on wealth because that’s the only thing that’s tracking alongside property valuations. Edit: basically peak capitalism
