  • When wind speed doubles, the energy it carries increases eightfold,

    Edit: I’m wrong, see edit below!

    Huh? Kinetic energy increase is square, not cubic.

    KE=1/2 m v^2

    So every doubling of speed should increase the available kinetic energy by 4 times, not 8. 3 times the speed is 9 times the energy. Granted there are probably some efficiency gains in excess of this at the low end, but as a rule that’s just wrong.

    Edit: Cool, I learned something new! I neglected to consider it in terms of power, just thought about kinetic energy.

    So something like: KE = 1/2 m v^2

    = 1/2 ( rho V) v^2

    = 1/2 ( rho A d) (d/t)^2

    = 1/2 rho A d^3 1/t^2

    Where P = KE/t

    Thus:

    P = 1/2 rho A (d/t)^3

    = 1/2 rho A v^3

    Lots of other aspects I’m sure I have wrong, but I see how the cubic came to be.




  • Ostensibly, that’s because the app wants Bluetooth and/or WiFi access so it can connect to the printer. Because you can use WiFi and Bluetooth to determine location (based on large crowd sourced databases of these data points that have been geolocated), the OS has to ask for location permission as well, even if you just need to see WiFi and Bluetooth.

    That being said, once they have this permission, I have 0 doubt they log the actual location as well…

    Mozilla used to run a free service for this, and collected that data in the background using mobile Firefox. A replacement is https://beacondb.net/, which is still building enough location data to become useful. Services like this aren’t nefarious, they’re actually really important in getting a quick GPS lock on mobile. Phone hardware actually have pretty poor GPS receivers, but if you can determine an approximate location prior, you get much better results, especially once supplemented with inertial measurements and snapping to mapped roads.




  • At risk of taking some bait…

    I profess a faith as a Christian, but am not a theologian. Grain of salt and all that, but we do exist lol

    Unfortunately sorting “real” Christians from posers is difficult, and that’s how people can get away with using the “Christian” label, because who can judge but God?

    That being said, when you think about whether someone is a “real” Christian who’s just not doing a good job, vs a poser who’s just using the name, consider whether they exhibit some of the very clearly articulated attributes of being a Christian, such as the Seven Virtues. If someone consistently calls themselves Christian, but makes no effort to improve in these ways, that might be a good sign they’re not genuine.

    So to your point, using Christianity for social gain is antithetical to actually being a Christian.

    I’m terms of Organized Christianity, and cases in which it has shielded those who do evil, that’s a big, messy topic. Sufficient to say, the church is wholely responsible for not taking it seriously for so long. It breaks my heart that it happens at all, and brings great shame that there are people who supposedly profess the same faith and yet allow these things to happen. The church can and should do better to hold one another accountable and to protect the vulnerable.



  • yeah my product is awful but have you seen the other guy

    Yeah, it’s this. I worked at Epic somewhat recently, and I’ve since worked with former Cerner/Oracle folks too. To Epic’s credit, they’ve never been acquired, and are better for it.

    There’s a lot of vocational awe across the board, people genuinely trying their best to make the product good. But healthcare is inherently complicated, because people are complicated. Each individual health system needs it customized to their specific needs, and over time this can get hairy to support. Add on to that that regulations and guidelines literally change every year, and it can become really hard to make headway on more meaningful changes when you’re just trying to stay compliant.

    This leads to burnout on the software support side, Epic churns through new hires like crazy - average tenure has been way down since COVID-19 (you can Google their response to that), so it’s a revolving door of 21-25 year olds keeping that ship afloat.

    Also, yes, insurance companies are the ones making the big money, by a mile.

    I used to drive on State Line past that lot full of Teslas daily, always saw a ton of Cybertrucks just sitting. Once Musk started getting so much (more) hate I figured it was a matter of time before someone torched it.

    Also, I always find it funny how it’s totally just a road that divides the states, I’d drive to work and be “in” Missouri and drive home “in” Kansas lol
