left-struck··on Fair coins tend to land on the side they started (2023)
>If indeed it's happening, the only explanation can be something to do with very deep Quantum Mechanics including multiverse theory

Why would that be the only explanation? that seems like very low down on a long list of possible explanations.

I didn’t read the paper but the author was discussing how some people impart precession onto the coin which is a likely explanation for causing a bias.

left-struck··on Australian real estate agent hallucinates two schools in rental listing
Well after looking at the map and finding a potential house then you need to read the description… Idk what it’s like these days but it used to be that looking at the map only or using the filters isn’t anywhere near enough because there’s plenty of “mistakes” that happen to benefit the listed property and bypasses your filter. Like listing a property as the wrong type, or listing a room for rent under houses for rent, etc.

A house purchase is a massive decision, why wouldn’t you read everything and anything you can find about the house, what are you even talking about lol

They absolutely do have beacons, called transponders, similar to what civilian aircraft have. Of course they can be turned off in a military jet. The article says the transponder was not functioning because of the electrical malfunction
left-struck··on EFF to Second Circuit: Electronic Device Searches at Border Require a Warrant
For some people, having the right to search their phone would be like having the right to search their mind, but that aside, there are so many ways to overcome the need to carry your data physically with you across borders. If you’re motivated to do so it’s easy to find a way, which means that the vast majority of people whose privacy is being invaded aren’t even doing anything wrong, and the people who are doing something wrong just need to be slightly tech savvy to get around this.
left-struck··on The motor turns too much
I believe petrol engines can do this too, and I didn’t mention it for petrol engines because the performance of the engine in that state won’t be anything like what it’s capable of, the rpm will go high but if you put any load on it the engine won’t be outputting a lot of torque or power. If this happens in a manual just push the brakes really hard while the car is in gear and clutch released, it will stop the engine. If it’s auto I guess you’re buying a new engine lol, but it’s not like the car is going to run out of control if you just stay calm

> On the Clio 2 car, there are two redundant linear potentiometer tracks. If the dual measurements don't match or if either sensor is disconnected, the ECU will default back to a slightly higher than idle throttle.

That’s really neat. I was thinking something along the lines of having a microcontroller with a good adc right next to the throttle pedal and its angle transducer (hall effect would be better) and having that microcontroller send a digital signal. If the ecu can’t make sense of the digital signal or it is missing, just set the throttle to idle. That’s a solution that would be reasonably cheap today though but not 25 years ago.

Anyway in my experience most Japanese and Korean cars didn’t have fly by wire until the 2010s

left-struck··on Trump wins presidency for second time
I think there’s this massive negative bias in a lot of our media, by our I mean globally. Social media and news. So I think you’re right, life is generally getting better for most people, COVID was a temporary blip in that trend. However… Inequality is growing rapidly between the middle class and the ultra rich, and the middle class in many developed countries is being squeezed due to cost of living issues, I think that’s a a part of the reason for this result. Also median income alone is useless, it has to be compared against cost of living. A measure of a middle class family’s ability to grow wealth is the difference between their income and their essential expenses. That is what matters.
left-struck··on The motor turns too much
You’re sort of right in your assumption but there’s a lot of context missing. First, the time period is more like 30 years for cars having engine control units (ecu), but most car up until 10 years ago or so had hard physically wired throttles where you stepping on the throttle pulled a physical cable. If that cable doesn’t get pulled the engine doesn’t get enough air to go really fast no matter what the ecu tries to do. More recent cars have fly by wire throttles meaning they are like electric cars in that sense.

An ecu has a far more complicated control algorithm than a electric motor controller. If it were suddenly damaged it’s more like that the engine would fail to run at all then run out of control because the ecu needs to control the airflow, fuel and spark position for the engine to run, if any of those fail to work, or stop firing at the right the exact time they are required the engine will just stop or run very poorly. I actually think this is true of electric vehicles too, it’s far more likely to stop the motor working than to have it run out of control, unless a wheel speed sensor is damaged or something.

A petrol car can be placed into neutral if all else fails, the engine will run out of control but the car wont. Also the gearbox controller is typically a different computer from the ecu.

The brakes on any car should be able to over power the engine. This is not a challenge for 99% of petrol cars because the torque they output is tiny compared to what a brake system can apply to the wheels. If you slam on the brakes the engine doesn’t even come close. Idk about other countries but in Australia this also applies to electric cars that are road legal, it’s a requirement.

the ecu is usually located in the passenger cabin or sometimes next to the battery quite deep inside the engine bay.

The only thing that would cause a petrol engine to really go out of control would be if it was fly by wire throttle and that throttle position sensor was broken in the particular way that it’s reading as full throttle. Idk if manufacturers do this but it wouldn’t be hard to design a fly by wire throttle that when it fails the ecu will see it as closed not open.

Anyway I don’t think it’s much of a concern for electric cars either tbh.

left-struck··on Sleep regularity is a stronger predictor of mortality than sleep duration (2023)
It deeply affects me. I’ve lived in places that have it and currently live where there is no DST. If my state implemented it I would try to negotiate with my workplace to keep the same actual hours so my schedule doesn’t change, if they refused I would consider moving, job or state.
left-struck··on Sleep regularity is a stronger predictor of mortality than sleep duration (2023)
Well obviously they would have severely impacted sleep? What are you trying to imply?
left-struck··on Sleep regularity is a stronger predictor of mortality risk than sleep duration
I used to do this as well sort of, my schedule would shift by a few hours every day. I found that it had a significant impact on my mental health when I was sleeping through the day though, and it made it difficult to participate in various aspects of society like work, education and in person social things. I was eventually able to “fix” it by taking melatonin as a supplement to fix a short term schedule and being super anal about not letting people pressure me into playing games late or staying out late. I basically reframed sleeping hygiene as a primary health concern and that worked for me.

Anyway if your schedule doesn’t impact you in a negative way then go for it

left-struck··on Sleep regularity is a stronger predictor of mortality than sleep duration (2023)
I agree with this except for the early part. At least personally waking up at about 8 works for me, that way I’m not waking up before sunrise in winter which makes me unhappy quite reliably.

A lot of people are weirdly proud of how early they wake up, and I’ve literally been shamed for waking up late, called lazy etc in a casual sense but that’s nonsense. I just work later.

left-struck··on Mac Mini with M4 Pro is the fastest Mac ever benchmarked
Topaz I can understand, but are you really struggling with performance in lightroom and photoshop? I have a 50MP camera and I don’t have issues with older hardware

Actually, I don’t know how like an M3 pro or better compares with a ryzen 5600 and rtx 3060, I assume much better cpu performanc and similar GPU performance?

left-struck··on Tesla's Cybertruck is outselling almost every other EV in the US
> I mean most cars you get a good five years out them anyway right?

Uhh no? You should absolutely expect a good vehicle, hell most vehicles, to exceed 10 years without serious failures. Many vehicles come with 7 year warranties on manufacturing defects… It sounds like you need to take better care of your vehicles or buy better vehicles. I did notice that you said she drives 200 miles a day and that will certainly contribute but if you take care of it, most cars would probably do that for 10 years assuming it’s mostly cruising. Either way that statement of 5 years is nuts. I bought a 5 year old car with 80,000km on it and it was in damn near new condition!

I’ve owned 6 vehicles, including one motorcycle, none of them from brand new mind you, and all of them were still reliable after their 10th year lol. Currently I have a 5 year old car which you can’t tell apart from the brand new 2024 models because it has no wear and the model hasn’t had a face lift, and I have a 35 year old ute (truck)… 5 years is nothing. I think the average age of cars on the road would be older than 5 years

left-struck··on The Japanese word ikigai refers to a passion that gives joy to life (2022)
To add to this, I would argue that ikigai can be directly translated to purpose in English. Sure purpose has additional meanings, and ikigai has a philosophy behind it which one word like “purpose” does not convey, but if you use purpose in a sentence that has something to do with how you find meaning in life and a reason to go on, then people will correctly understand your meaning.

If purpose is not good enough then try “a reason for being” “a reason to live” etc

Maybe people are confusing describing a whole philosophical concept with translating a word

left-struck··on MrBeast's Faux Philanthropy
No you’re totally right, and Derek from Veritasium does point out that being hated shouldn’t be a moral compass. I think the point is more that you should know that even when you’re doing something right some people, maybe many people, will hate you for it. Incidentally if you’re doing something wrong you might be quite popular as well. Popularity isn’t a good judge of character.
left-struck··on MrBeast's Faux Philanthropy
Politicians in democratic countries are inevitably hated by roughly half the people, and that’s if they are popular!
left-struck··on MrBeast's Faux Philanthropy
Yes exactly. It reminds me of this video by veritasium, which is in turn inspired by Adrian Tan where he says “Be hated” and describes how in being successful you should seek to be hated by those with poor values. Not that I agree with everything Elon, Mr beast or Veritasum does by any stretch, but they have all seemingly embraced this. I also think it’s inevitable with fame, and perhaps a good check on the actions of those with power.

If I were Mr Beast and I read this I’d shrug it off and think you can’t impress everyone. Again, I don’t agree or even follow what he does but it actually doesn’t matter, if you do good, or bad, or do much of anything notable, you will attract hate.

left-struck··on Wikipedia article blocked worldwide by Delhi high court
I think there’s a difference between human rights and legal rights. For instance people in North Korea have a right to freedom of thought, all people everywhere do, but that doesn’t mean their government recognises that right, or that they have the legal right. India, mind you, doesn’t have the legal right to block me from viewing this Wikipedia article in Australia, but it seems like they have the ability to do so.

I guess ultimately this comes down to whether you believe a government and the rights it enforces is legitimate because it has the biggest guns, or because that government was decided by the people, or the legitimacy is determined by the ethics of the government etc

left-struck··on BYD EV teardown in Japan reveals secrets to its affordability
Of course Indian people are going to promote India brands on Indian social media, even if they aren’t being paid. I would be surprised if I didn’t see that, not if I do see it.

This story is so old, here’s how it goes: Germany used to manufacture the cheap vehicles after ww2 ended, then Japan started getting their shit together and they started undercutting german cars, then German car manufacturers, noticed they were losing market, so they started marketing their vehicles as more premium, better quality and more exclusive, with a higher price tag. They can’t compete in the same market as Japanese cars so they go to a new market, and they genuinely had been manufacturing for longer so maybe the cars were better quality. Then Japanese cars build a reputation as the manufacturing improves and South Korea starts producing cheap cars as well so now the Japanese manufacturers have to market their cars higher up in the market. Then china comes along… next is India, after that Africa. Along with this , in each of those countries goes the increasing number of middle class citizens and rising costs due to better pay and standards for those citizens… Alright this is a oversimplified version but like dude, of course indian social media is going to praise indian cars.

left-struck··on US probes Tesla's Full Self-Driving software after fatal crash
That’s hilariously ironic because I have a pretty standard newish Japanese petrol car (I’m not mentioning the brand because my point isn’t that brand x is better than brand y), and it has no ai self driving functions just pretty basic radar adaptive cruise control and emergency brake assist where it will stop if there’s a car brake hard in front of you… and it does a remarkable job at rejecting cars which are slowing down or stopped in other lanes, even when you’re going around a corner and the car is pointing straight towards the other cars but not actually heading towards them since it’s turning. I assume they are using the steering input to help reject other vehicles and dopler effects to detect differences in speed, but it’s remarkable how accurate it is at matching the speed of the car in front of you and only the car in front of you, even when that car is over 15 seconds in front of you. If teslas can’t beat that, it’s sad
left-struck··on Code that helped end Apartheid
I think mass refusal to work and spend money to the point where it starts inflicting enough pain on the government to take the desired action, would also significantly affect people who have nothing to do with the conflict, and it would have a greater effect on the poor than the rich as recessions tend to do.

I’m not sure if that would be an ethical course of action outside the country where the oppression is actually happening.

left-struck··on Starship Flight 5: Launch and booster catch [video]
I remember playing KSP, I had used some mod to program a moon lander to do a suicide burn, a maximum thrust burn to land. I did the maths myself and when it actually came to the landing I was 100% certain I had either a bug in my code or did the math wrong because I was coming in way too fast, or so it seamed, but to my surprise the thing slowed down in time! Mind you ksp is way simpler than the real world and the spaceship could handle some… error, the landing was hard but successful

Point is it always seems like you’re coming in too fast

left-struck··on A Photo of the Moon
>I guess what I'm asking is if it looks so colorful when you look at it with your eyes from low orbit.

To be honest, I don’t know

A lot of the colour in these images just blurs together at the scale we see the moon at from earth, at least with my eyes, and that would still be true in low earth orbit.
