  • There’s a lot of armchair snipers all of a sudden who are saying they can hit a few inch group at 100 yards with their eyes closed.

    Given lemmy’s demographic, I’m not sure how many of these people have actually held a rifle, let alone tried to shoot it at +100 yards while under a time crunch and stress.

    Not saying what the kid did was right, but criticism of his marksmanship isn’t really fair.



  • If you have a modern receiver, like any smartphone from the last 10 years, gps is accurate to a couple of meters.

    It’s only a couple of meters for a few of reasons: necessity, speed, and scale.

    It’s not necessary for most users to have centimeter precision for gps. Most uses for GPS is for humans to find a place, most humans have eyes, or can at least read braille signs. So if you’re looking for a pizza place and your gps says you’ve arrived, you can look around and see that the pizza place is 3 meters down the road.

    Speed, because you can get really accurate locations out of gps, but your receiver would need to refine your location by talking to many satellites many times, which isn’t needed for most users as just knowing if you’re on the right street and the right side of the street is enough. Many communications would mean it takes a long time for the gps device to determine a precise location, which is frustrating for your average user.

    And scale, it’s a really big planet, and there’s a finite number of gps satellites. The less satellites in your network, or the less they’ll talk to your receiver, means less accurate data and a less accurate location.

    TLDR: most people don’t need sub meter precision from their gps, so it’s simply not provided to most people.






  • Spending a Thousand dollars on a glorified legal pad sounds clinically insane.

    I have a TV for watching things at home.

    I have a phone for watching things on the go.

    If I need to look up information outside my house, again I have my phone which I already pay to be connected to the internet. You need an additional line on your plan for a data connection on an iPad, or rely on public WiFi.

    If I need to take notes on something, I can use a 1 dollar legal pad or notebook, which is barely bigger than an IPad and will never run out of charge. If I need to take so many notes that I’ll fill up an entire notebook, I’ll probably just ask to record the thing as a voice memo on my phone.

    I’ve still never been convinced that an iPad is a useful device, and I don’t see any way the Vision Pro will be useful for anything other than inundating us with advertising for a larger percent of our existence. God forbid someone spend 10 minutes not looking at their phone and generating revenue for an ad company, now they want to literally strap them to our heads.



  • Several things can be true at the same time.

    Starlink exists to give SpaceX nongovernment launches to boost its numbers and make it look good as a stock.

    It also happens to provide a service at what is almost certainly a loss, considering each satellite only lasts a few years and thus requires a constant stream of replacements to be launched.

    It also happens to fill the sky with a bunch of garbage that will inevitably hit something and lead to a spray of even more garbage.


  • Flirting with Kessler syndrome so you can land trick shots in Fortnight.

    The only benefit starlink has over transitional satellite internet is relatively low latency, you could have gotten a different satellite provider.

    Just because there hasn’t been a collision yet, doesn’t mean there won’t be. And there has been measurable damage to ground based telescope observations due to the constant stream of starlink sats overhead.

    Did not have an identified serial killer until 1903. Both of these killers were white and killed white victims.

    I don’t think the police were really looking into crimes against black people in South Africa at the time. It’s entirely possible there were several serial killers that targeted non-white victims to avoid detection.
