adamjb··on Jevons Paradox
That's just the paradoxical thing about it though. With induced demand congestion doesn't improve so travel times don't improve, so there is the same (dis)benefit to moving as there was before and living elsewhere doesn't, or rather shouldn't, become an option.
adamjb··on What the world will be like in a hundred years (1922)
I live in a suburb with a power station that was converted from coal to gas in the 70s. My older neighbours have told me that they had to careful when hanging clothes out to try, lest they got so dirty that they'd have to wash them again.

adamjb··on Monitoring my home's air quality with AirGradient's DIY sensor
The last time AirGradient popped up on HN, the guy who runs it said if you get in contact and ask nicely they might have a spare one to send you.
adamjb··on Australia’s new mass surveillance mandate
Unless the exposure site is identified as a low-risk one where contacts are directed to isolate until they get a negative test, no. You have to do a test when going into iso and you have to get a negative test on day 13 to leave it. There have been plenty of cases where the day 13 test is positive, even when the test at the start was negative.
adamjb··on Australia’s new mass surveillance mandate
The phone check in thing is for enforcing the two weeks home quarantine for returned travelers and close contacts of confirmed cases. While there are certainly slippery slope arguments to be made, let's not act like we've already slid down it.
adamjb··on People Who Draw Lines on Maps Are the Problem
>Meanwhile the argument in opposition says that they were lying about the cost- instead of the $20 billion proponents were promising (they rounded up, of course, and assumed 1:1 federal matching funds), it would likely cost $90 billion, according to the opponents, which would make it “the most expensive railroad in history”. This is a rare situation where participants in a public debate understated their argument. In fact, the full cost of the train, according to the Los Angeles Times this past February, is now over $100 billion! Even the initiative’s opponents underestimated what a boondoggle this was!

One thing you don't see clarified very often when talking about the costs of megaprojects is inflation. $90 billion in 2008 dollars is $114 billion in 2021 dollars, meaning that the apparent cost blow out (against the opposition estimate) could just be an inflation induced illusion.

adamjb··on Squatting or Kneeling May Be Beneficial for Health
That's not what the article is advocating at all. A table bend is basically a deadlift. It's all about keeping the back straight so the heavy lifting is done by the hips and legs.

My first instinct is that its the same logic as to why gambling gains are tax free: because otherwise the losses would be tax deductible.

adamjb··on What Is Voter Satisfaction Efficiency?
The machines at the polling places can only count first preferences. Distribution of preferences will occur once the votes are transferred to the central scrutiny centre.

adamjb··on What is ranked-choice voting and why is New York using it?
>Yes? I said those 4 examples use different election styles, not that Canada doesn't use FPTP...

FPTP is a winner takes all electoral system. You said Canada had "a parliament where seats are assigned proportionately to votes (there's no winner take all)".

>Winner-take-all refers to

>>> a legislative body is elected by dividing the jurisdiction into geographic constituencies, each electing exactly one representative. Although this may result in diverse representation due to different political groups making up majorities of different districts, within each district, only one political party or group will be able to elect a candidate[1]

This is exactly what Australia and Canada's lower houses have. And looking it up now, France too.

>considering the impracticality of implementing a non-winner-take-all system without a significantly larger number of representatives

The Australian senate has 76 senators. The Australian house of Reps has 151 members. The Australian senate elected with a non-winner-take-all system. The Australian house of reps is elected via a winner-take-all system.

>If we give more seats and apply proportionate seating this is functionally equivalent to just dividing the electorate further and using winner-take-all.

It is not. To illustrate: imagine a country of 1 million where instead of left-wing and right-wing parties they have left-hand and right-hand parties. So there everyone votes for the right-hand party except for the 10% of people who are left-handed. As handedness is fairly evenly distributed, in a single member electorate system it would be basically impossible for the lefties to take a single seat. So you'd expect the parliament to be 100% right-hand party no matter if it comprised a single member or 10,000. However with a proportional system (e.g. SLV) with electorates of 10 or more you could expect the parliament to roughly reflect the 90/10 split.

We see this in the real world, where places with single member seats (e.g. Canada, France, Australia lower house) have worse parliamentary diversity than those with multi member seats (e.g. Germany, Australia upper house).

>And if this is why you're throwing my comment out the window I think you missed the entire point and I do not appreciate the lack of good faith here.

As you haven't made it very clear at all, what is your point?

adamjb··on What is ranked-choice voting and why is New York using it?
>who also uses MMP (like Australia)

Australian federal lower house elections are single member IRV, upper house are multiple member STV. MMP isn't used anywhere in Australia.

adamjb··on What is ranked-choice voting and why is New York using it?
>These 4 countries have 4 different voting systems but what they have in common is a parliament where seats are assigned proportionately to votes (there's no winner take all).

That is wrong. Australian lower house seats are single member aka winner takes all.

edit: and Canada is FPTP

adamjb··on Holden's Lightning Flight
Interesting tidbit from the first person account linked as a reference

>Some years after the incident, my hidden fears of high speed flight came to the surface and I had to spend two periods in hospital. I had not come to terms with the emotional side of the event. To return to my wife and family, after five close encounters with death, was indeed a miraculous experience, but I had not been honest with myself, to accept it as such, so I needed psychiatric help. I could recall the technicalities of the flight without any hang-ups, but was unwilling to talk about that emotional side of the ordeal until I was placed under medical drugs and to bring these emotions to the surface. That was a rewarding experience and it gave me a much better understanding of people who might need that kind of help, after similar unfortunate occurrences

adamjb··on Refinement Culture (2020)
This deserves to be shouted from the hilltops

>In human relationships we can't optimize without becoming greedy selfish unethical crooks. And in commerce we prefer relations to transactions, ready to support the local butcher because we feel we are part of a community and we are not alone --we are paid back with a smile and someone who says hello in the street. Indeed the central flaw in optimization is thinking that "everything else" ceases to exist and makes people think the individual, not the collective, is the true unit --when such thinking blows up the system. We humans are punished when we try to optimize, as if we suddenly ceased to be humans.

adamjb··on The Tyranny of Time
From TFA

>In places where globally standardized time is enforced, some still rebel, like in China, where the entire country is under one time zone, BST (Beijing Standard Time). In Xinjiang, nearly 2,000 miles west of Beijing, where the sun sometimes sets at midnight according to BST, many Uighur communities use their own form of local solar time.
