Those are the comments that should persist in the code. I hate when the AI edits and removes my "why" comments. I want the refactor to make it less messy but keep why it's that kind of mess.
If you do positioning in degrees, minutes, and seconds (or decimal minutes which I guess is more common nowadays), a 'natural' length unit for navigation is a minute of longitude, which is the original definition of the nautical mile. And then we get velocity as nautical miles per hour, or knots.
Blame the French for reinventing the wheel instead of, say, using a 1/1000th of a nautical mile as the definition of the metre. Alas, that's all water under the bridge by now.
If you want to do navigation in SI units, the UTM projections (see sibling thread) typically do positioning in metres inside each grid square.
Funnily enough the metre is defined by the globe as well: the arc from the equator to North pole is defined as 10,000 km. I think this might be where the alternative angle metrics came from, which went with the metre:
full circle is 400 grad, so a right angle (10,000 km) is 100 grad.
Then minutes and seconds are factors of 100, so a centesimal minute is 1 km and 1 centesimal second is 10 m.
Originally it was defined like that, but it was fairly quickly redefined as the distance between marks on a prototype platinum bar. It's had a couple of other definitions since then, but it's currently defined "by taking the fixed numerical value of the speed of light in vacuum c to be 299 792 458 when expressed in the unit ms⁻¹, where the second is defined in terms of the caesium frequency ΔνCs".
Yes technically speaking there is a different physical reference now but that's where it came from. A bit like how 1 ft is now 304.8mm but that's because it's the size of a human foot (with some historic details no doubt).
> that isn't a change to the definition of the meter
How is it not? it's not a change to the actual distance (well, it is for a sufficient precision), but a change to the definition of the metre is exactly what it is. It's defined relative to the speed of light rather than a random platinum bar length, with the constant picked so that the actual measurement stay the same (up to a certain level of precision).
And only 1852m at sea level; since it's an angular distance it's a bit longer in the air and a bit shorter underwater (~ 29 cm per km of elevation change).
Though surely to say a system or process is 'retarded' means something is holding it back?
To equate this to a derogatory term for a learning disability (worthy of self-censorship!) is, frankly, bizarre and rather smacks of virtue signalling.
broadly speaking, it _is_ factually incorrect to say that. Censorship is the government controlling what information the public can access. No one on "the left" is trying to pass a law saying that people should get jail time for using the R-word.
Political correctness, woke/cancel culture, whatever you want to call it, is not censorship. And it's not splitting hairs to say this; words have meaning and though 'censorship' is particularly abused, it is still quite different from me looking down on someone who uses the R slur on X (as I do daily)
> Censorship is the government controlling what information the public can access
Wikipedia and the ACLU both use a more expansive definition, where your definition is only 1 type of censorship. The "Left" uses empathy to convince people to self-censor and less often uses "Cancel Culture" to pressure companies into private censorship.
There are more subtle forms of censorship, continuously employed by the government to prop up or push down various things. Covid had many such examples of pressure tactics from the government come to light but I'm sure it happens constantly.
For a specific recent example democrat-leaning states had much stricter and longer-lasting covid lockdowns - preventing free association is a form of censorship.
The Christian right was trying to ban books in the 70s/80s. Fought heavy metal music in the 80s. Then you have 911 censorship. But after 2008 the left brought woke to power which saw banning people from twitter, social media, right speech. Then we reached covid which saw banning of facts. Deplatforming / banning / doxing became the norm until the return of Trump who then moved the needle and started pro Jewish censorship which has pushed the needle for the anti Jewish censorship crew which is taking over.
Harry Potter is the funniest example because it started out being a target of the evangelical "right" and has become a target of the culture-war "left"!
I remember taking a California statewide essay exam in middle school whose prompt was specifically to argue for or against banning Harry Potter from the school library. I wrote a stridently anti-censorship piece extolling the virtues of literary freedom and calling out the censorious right for attempting to use schools not to educate, but to transmit catechism.
The essays were graded by (obviously heavily left-leaning) teachers from all over the state, with two teachers independently assigning a score and if their scores differed by more than one grade, another teacher would be tiebreaker.
I got the top score from both teachers--one of only a handful in the (large) school district. I even got an award from the local newspaper.
Now I see the same demographic take the polar opposite view and it's disappointing to say the least. Especially after the "anti" racism struggle session era, it seems to me that their real issue with the book bans wasn't the censorship; they just wanted to transmit the "right" catechism.
How did the institutions dominated by the left react to dissent when it came to COVID 19 policy? Like the authors of the Great Barrington Declaration. Were they open with speculation about the virus, vaccine policy or the lockdowns? Or did they censor Disinformation and Misinformation on Campus, on social media,and at the work place?
