    Yes, but blue (Mercator) preserves direction and shape, which were all that really mattered for navigation by sea, so Mercator was a fantastic projection for centuries.

    And we still use it today for smaller scale areas, since it does a remarkably good job at preserving all 4 features (shape, area, distance, and direction) close to the map origin line. Universal Transverse Mercator is a system that has 60 zones of Mercator turned sideways.

    The reason it’s Transverse is because, unlike lattitude depending on a defined equator, longitude has an arbitrary meridian, so by turning the map sideways we can move the distortion point, and any map area that doesn’t stray too far East or West will be very accurate.

    Think of trying to map something like Chile or Florida, where the area of interest is pretty far North to South, but not East to West.


  • My GIS rig is different than any of those.

    Vertical monitor on the left, ultrawide lifted a bit high on the right, and open laptop screen beneath the ultrawide.

    Verticals for email, teams, etc. Big ultrawide is mostly for main GIS window and spreadsheets, and laptop screen is kinda general purpose.

    I actually have a 4th monitor technically, but it’s a big TV on the wall of my office that’s usually turned off, but that I can use for presentations or screen-sharing when I’m meeting with people in my office.


  • While the National Guard is prohibited from performing law enforcement on behalf of the President under the Posse Comitatus Act, the governor of the state they’re operating in can deputies them.for law enforcement.

    He doesn’t need to wage war on ICE. He just needs them to be chaparroned by armed Nation Guard troops anywhere they go, and have them arrest ICE goons when they violate the law. If ICE gets proper judicial warrants and executes them lawfully, then there shouldn’t be any problems.

    An important distinction on warrants is that an immigration judge cannot issue a judicial warrant because even though the word “judge” is in their title, they aren’t part of the judicial branch. They’re employees of the executive branch, so any warrants they hand out are administrative in nature and cannot legally be used to enter private property without consent.







  • I’m a third-party non-employee lecturer at my local university. I teach scuba, underwater photography, and scientific diving. The courses are taught off-campus at a dive shop using the shop’s its classrooms, pool, and equipment. The liability insurance is paid by me.

    There’s a lake on campus we dive at, and the university charges students to enter it.

    The students have to pay $3000+ in tuition for some of my classes.

    …and the university doesn’t give me or the shop a dime. The students have to pay a 200 dollar lab fee, and that’s split between me and the shop for the semester. The only thing the university provides is the course numbers and taking the money, and they get 30 times as much money as I do.

    I have multiple individual cameras I use to teach the class that cost more than I make in 5 years of teaching the photography class.

    And they want to charge me $800/year for parking for the rare occasions when I need to go on campus.

    Fuck that - I just let them ticket me. The parking services department isn’t a law enforcement agency. The biggest threat they really have is withholding grades for students who owe parking tickets.








  • The third game also had that horrid “menuless” interface.

    And in a series where magic was so OP it made other combat options useless in comparison, it had by far the most OP magic.

    A maxed-out melee or ranged character would take twice as long to kill a single enemy as a low-level mage would take to kill a group of 10 enemies.
