Trump is “absolutely” immune for “official acts” on Jan 6th, SCOTUS rules
  • The person you're arguing with made the point that if you hold the ones who voted against the bad thing happening as partly responsible, by the same logic, you should hold people who voted for Clinton in 2016 partly responsible for the election of Trump.

    I don't think you can have it both ways. Either the entire USA including you is responsible for Trump becoming president and the entire SCOTUS is responsible for today's ruling, or you're not responsible for Trump winning and the three dissenters are also not responsible for today's ruling.

    I get that you're angry, and it's a good day to be angry, the day that they ended democracy, but maybe be more selective about who you're angry with and sometimes try to check if maybe there are some valid things people can disagree with you about.

  • We coulda had Bernie...
  • Uhhh and today the SCOTUS decided that Trump can never be prosecuted for anything he did or will do whilst president, so actually, democracy died today. Biden won't abuse this. Trump will, and there will be nothing to stop him from enacting his dictator plans. About that, and the political assassinations, and the president for life, I think Trump is serious.

  • Worst is UTC vs GMT
  • UTC exists as a historical compromise because the British felt that GMT was the bees knees and the French felt differently. The letter order is most definitely a compromise between French and English word order. You can call it Universal Time Coordinaire.

    Historically, GMT became the international time reference point because the Greenwich observatory used to be the leader in the field of accurately measuring time. It probably helped that the British navy had been dominant earlier and lots of countries around the world and across time zones had been colonised by the British.

    UTC is an international standard for measuring time, based on both satellite data about the position and orientation of the earth and atomic clocks, whereas GMT is a time zone. Nowadays, GMT is based on UTC not independent telescopic observation.

    What's the difference? You can think of a time zone as an offset from UTC, in the same sense that a 24h clock time is an offset from midnight. GMT = UTC+0.

    Technically, UTC isn't a valid time zone any more than "midnight" is a valid 24h clock time. UTC+0 is a time zone and UTC isn't in a similar sense that 00:00 is a time in 24hr clock and "midnight" isn't.

    Of course, and perfectly naturally, I can use midnight and 00:00 interchangeably and everyone will understand, and I can use UTC and UTC+0 interchangeably and few people care, but GMT = UTC+0 feels like the +0 is doing nothing to most eyes.

    Fun fact: satellite data is very accurate and can track the UTC meridian independently from the tectonic plate on which the Greenwich observatory stands. The UTC meridian will drift slowly across England as the plates shift. Also, the place in the stars that Greenwich was measuring was of by a bit, because they couldn't have accounted for the effect of the terrain on the gravitational field, so the UTC meridian was placed several tens of metres (over 200') away from the Greenwich prime meridian. I suspect that there was a lot more international politics than measurement in that decision, and also in making the technical distinction between UTC and GMT, but I'm British, so you should take that with a pinch of salt.

  • Worst is UTC vs GMT
  • The problem isn't having empty values, it's not tracking that in the type system, so the programmer and the compiler don't have any information about whether a value can be null or not and the programmer has to figure it out by hand. In a complex program that's essentially completely impossible. The innocently created bomb that causes your program to crash can be in absolutely any value.

    There are ways to track it all by disallowing null and using optional values instead, but some folks would rather stick with type systems that haven't moved on since the 1960s.

  • Worst is UTC vs GMT
  • In a discussion about whether null should exist at all, and what might be better, saying that Optional values aren't available in languages with type systems that haven't moved on since the 1960s isn't a strong point in my view.

    The key point is that if your type system genuinely knows reliably whether something has a value or not, then your compiler can prevent every single runtime null exception from occurring by making sure it's handled at some stage and tracking it for you until it is.

    The problem with null is that it is pervasive - any value can be null, and you can check for it and handle it, but other parts of your code can't tell whether that value can or can't be null. Tracking potential nulls is in the memory of the programmer instead of deduced by the compiler, and checking for nulls everywhere is tedious and slow, so no one does that. Hence null bugs are everywhere.

    Tony Hoare, an otherwise brilliant computer scientist, called it his billion dollar mistake a decade or two ago.

  • Worst is UTC vs GMT
  • Well, UTC didn't exist in 1800, it would have been GMT, and that might not have been too popular so soon after the war of independence. Even if you convinced all of the USA to use one time zone for the railways, it would be different elsewhere and you'd still get time zones.

    Maybe you'd get further with the project with the airlines in the first half of the twentieth century, but I'm not sure that that level of internationalism would have gone down well in a rather war torn world.

  • Worst is UTC vs GMT
  • Yeah, Seasonal Affective Disorder is a recognised medical condition and its symptoms get worse the further from the equator you live. Don't know why folks are downvoting you for having it.

  • USA presidential candidates
  • Just a reminder to our American cousins that in British English, trump means the noise an elephant makes but also to fart: "Sorry I trumped." Donald the Trump is a noisy noxious unwanted thing on the world stage.
