My current trick for aerobic exercises is... Beat Saber. It's a rhythm game for VR headsets, in which you use your controllers as light sabers and have to cut apart cubes and avoid obstacles, all to the beat of music. At higher difficulty levels it gets pretty intense, so it works great as an exercise, and it's also fun. You don't even notice when you start sweating from exertion.

My wife and I talked a lot about getting a dancing mat, which was my college friend's go-to exercise technique (he ended up going semi-pro and winning some awards in StepMania competitions), but dancing mats - especially hard ones - make a lot of noise, making them unsuitable for use in an apartment in a block of flats. Dancing games have similar benefits - exercising becomes fun, and there's built-in progression to guide you. But after Oculus Quest - a standalone, untethered VR headset - came out, we decided to go the Beat Saber route. Waving hands doesn't make the noise stepping does, and untethered headset is even more portable than the dancing mat.
Indeed. For me, the worst bit is that they explicitly, for no reason other than to inform us, say they won't be able to repair the damage.

That's a pretty bizarre thing to believe. Who is building these machines? Intel? No other organization within the US has the lithography capabilities to manufacture cutting-edge computing hardware, much less "years ahead of anything any of us will ever touch in our lifetimes". Perhaps it's aliens?

In some areas governments put up signs like this without stopping to complete the triviality of actually passing a law allowing them to do so.

Whereas there might be nothing whatsoever wrong with such a law you can't legally fine or arrest people for not following instructions you were never legally authorized to give. Essentially anything you put on a sign doesn't gain the force of law.

Example GA went through some drama regarding that notably their local chief of police publicly stated

http://dunwoodynorth.blogspot.com/2017/12/dunwoody-homeowner...

residents in my neighborhood were looking for relief from this cut thru issue along with more enforcement of speeding, stop sign violations and trucks also cutting thru. I reached out to Chief Grogan to share the neighbors concerns and asked that he have the Dunwoody legal staff research the legality of enforcing the "No thru Traffic" on public streets as I personally see the issue as unenforceable.

I wouldn't be surprised if some neighborhoods or property owners also put up fake signs. Wouldn't be the first time.

Eastern Europe is way past the point of consuming ressources that can be renewed. Europe as a whole is also currently signing a trade deal with south american countries, and eastern europe is going to benefit from it.

From an eastern european point of view, it is easy to focus on western europe and see oneself as disadvantaged, but if you count ressources consumed the picture is very different.

One of my sons is a very picky eater and he has a strong aversion to certain food textures.

Some foods we can get him to eat by being insistent.

But with some types of food it's pointless. He will try them if we are insistent enough, but it makes him gag and regurgitate.

His one year younger brother eats pretty much anything, so I don't think it has anything to do with us being too lenient.
> corporations don’t want it, politicians don’t want it

Hmm, the question that then arises in my mind is: are parents that do encourage their children to question them properly preparing those children for a society that will disregard them with that attitude?

(Working from your assumptions here - I'm not necessarily sure how widespread the disregard for a questioning attitude is.)
Fair point. Still a dreadfully callous comment.
Too many people is the real problem.
Great article, and some great links from it too. The list of models "following the letter but not the spirit" at https://docs.google.com/spreadsheets/u/1/d/e/2PACX-1vRPiprOa... has some hilarious and creative examples that one would hope never make it into production:

> AI trained to classify skin lesions as potentially cancerous learns that lesions photographed next to a ruler are more likely to be malignant.

> Agent pauses the game indefinitely to avoid losing

> A robotic arm trained to slide a block to a target position on a table achieves the goal by moving the table itself.

> Evolved player makes invalid moves far away in the board, causing opponent players to run out of memory and crash

> Genetic algorithm for image classification evolves timing attack to infer image labels based on hard drive storage location

> Deep learning model to detect pneumonia in chest x-rays works out which x-ray machine was used to take the picture; that, in turn, is predictive of whether the image contains signs of pneumonia, because certain x-ray machines (and hospital sites) are used for sicker patients.

> Creatures bred for speed grow really tall and generate high velocities by falling over

> Neural nets evolved to classify edible and poisonous mushrooms took advantage of the data being presented in alternating order, and didn't actually learn any features of the input images
> Imagine not being able to believe your own memory.

Done. Memories are notoriously unreliable and you shouldn’t treat as ultimate source of truth.

It is easy to make tomato sauce without any ketchup (like in spaghetti with tomato sauce); To me it tastes much better than ketchup, but I wouldn't know how to preserve it for a week or longer.

I mean ketchup kills all the ingredients but it doesn't turn into a tasteless mess; that's quite an achievement.

Utopia, Abandoned: The Olivetti Town
Attributing a lack of trust to specific technologies themselves is a red herring

And my case is that it's not. More specifically: advances in communications and information technologies inherently and intrinsically undermine trust mechanisms in institutions and human interactions. They do this, in part, by replacing that trust with technological surveillance and verification. Which is, I'll note, more scalable, and possibly more reliable. But also insidiously corrupting of the social mechanics which have been established over time.

I'm probably not expressing this well, for several reasons. One is that I'm still thinking through this, and I'm not entirely convinced of it myself, though I'm fairly confident of the relationship.

In geographically-distributed pre-technological societies -- any empire (Roman, Chinese, Persian, Hindu, British), you had institutions -- business, courts, religions, governments -- which opereated without anything remotely resembling high-speed communications. Letters would take weeks, or months, to cross oceans. High-speed communications involved couriers on horseback -- the Pony Express largely replicated a 2,000 year old technology first established on the Royal Road of Persia, in which messages could travel 1,600 miles in about nine days. More liesurely transits took three months.

Ships sailed only from May to November, and couldn't sail close to the wind. For six months of the year there was no effective communications. Explorations and even cargo voyages might take several years.

In all of this all parties had to trust the others. Perhaps not perfectly, but sufficiently. And there were numerous mechanisms in place to effect this.

When we talk of technologies -- photographs, audio, video -- allowing us to "no longer rely on eyewitness testimony", what we're saying is that we are deprecating human testimony. Not without reason, but also not without consequence. And when the application of technologies presumes distrust, as social credit systems, email and keystroke monitoring, and pervasive closed-circuit video all do, the rot runs deeper.

If the trends aren't absolutely inherent and intrinsic, they're very, very close to that.
s/train/{car|plane|coach|tram|bus|bicycle}/

No transport is free of movement or vibration, cars most especially. Far more get car and air sick than train sick. So unless you're advocating never travelling at all, I'm not sure what point you're making.

From my experience of all, train is probably the most comfortable of the lot, with the best seating, most desk space - you get a proper table and even a mains point. You don't get forced to breathe dry low oxygen air, and avoid the nasty taste of road fumes.

Biggest negative is the relative cost of train compared to all the other forms of transport, which speaks more of relative subsidy than inherent costs.
I am always a bit baffled when, after decades of living in a globalized economy, people who are part of advanced economies claim they have no connections to events, driven by economics, occurring on the other side of the world.

If you eat meat regularly, you are connected to Brazil's deforestation, either for cattle or for soy feed. If you have invested in the stock market, you are most likely connected to the international flow of capital, which is also driving said deforestation.

Even if you are not doing any of that, you are still connected because you live in the middle of a society that reaps economic and material benefits from the structures that ultimately incentivise said deforestation.

The price gouging for larger drives is common all over. The inability to do it yourself is rare.

There's very little that can go wrong when cloning a 2TB or less drive and it requires $10 of extra hardware.

If you're happy with installing your OS from scratch, like you would when switching to linux, then there is basically zero reason to hesitate on putting in a new drive. Drive bays are designed for easy access.
I think they're implying that the leaks often don't say what people think they say.

Not just personal gain. The benefits of industrialisation and capitalism have been tremendous for people’s quality of life, stability of their food supply, access to medicine, work hours, work conditions. If it has an impact on the climate it is regrettable and should be mitigated as possible, but it is still a major net positive.
Indian and Thai food is amazing. They might not be strict vegetarian as they still use fish sauce or ghee, but it's doable.
If it's the texture of the food then it's possible he wasn't exposed to vegetables prepared in the right way. I can't stand cooked veggies (I've read there's a connection between this and perforated eardrums) and if I hadn't discovered I like them raw than I probably wouldn't eat many even today.
I can definitely see that happening. At one high school summer program held on a college campus, I basically ate nothing but bagels and cream cheese for three and a half weeks. I put most of my spending money in a TI-89 and mechanical pencils, the rest in Pepsi.
I've had texture sensitivity since I was a small child. Some types of food will literally make me vomit or get near to that point and it doesn't matter whether I keep trying to eat them. Lots of vegetables happen to have similar texture that causes a similar reaction, but not all of them, so I do what I can there. Fish is a similar problem, so sushi turns out bad every time I try it.

Combine that with food allergies (severe to the point of causing seizures in childhood) and it's pretty reasonable to not be super into wanting to try lots of new stuff and eat it after it makes me feel bad, no?

Sometimes I go out to eat with people even though the restaurant doesn't have anything safe to eat, you know, out of courtesy? I guess that's entitlement culture.

Something that I see rarely discussed when it comes to solar power and inverters is how a large part of the expense of an inverter stems from its internal temporary energy storage eelements (could be capacitors, could be inductors).

Assuming illumination is constant in timescales of minutes (so thousands of electrical AC cycles), one can observe the following conundrum: a solar panel produces DC electrical power, while most consumer devices assume AC power input. So when designing (or choosing) an inverter one can make 2 choices in theory.

If one draws on average half the current a solar panel can supply, the other half of the energy will simply recombine in the solar cell, heating it up.

I will assume a resistive load (as a well designed product should not reflect energy back in the grid).

An AC grid voltage is sinusoidal, and for a resistive load the current is also sinusoidal (the relation of course being U=RI)

The power is P=UI=RI^2. so the power is also oscillating sinusoidally, centered about the average power.

This seems to forces us to choose between the following 2 options:

1) have the inverter use all the incoming power (requiring electrical energy storage within the inverter: energy storage capacitors or inductors, which is expensive) or

2) have the inverter draw half the solar panel power (the other half is wasted as heat in the ), or have 2 solar panels (half the energy again wasted) to reach the same output AC power as 1); the inverter can theoretically convert the DC power to AC this way

But in reality there is a third way, if you don't mind having 2 outlets where the AC voltages come out in quadrature. If two AC outlets deliver the same average power with the voltages in quadrature, then the powers will be in counterphase, so no energy storage capacitors or inductors are needed (cheaper inverter per watt), and no energy is wasted (full utilization of the solar panels). The only downside is that you can't deliver the total power to one and the same device. But consider some high-way stop convenience store in the desert with multiple refrigerators, say an even number of off-grid refrigerators, then who cares if half of the refrigerators use AC power in counterphase with the other refridgerators?

A similar reasoning could be used for houses in a street, where the even houses and the odd houses are powered in counterphase (voltages in quadrature), which would substantially decrease the costs for inverters.

What Statistics Can and Can’t Tell Us About Ourselves
But you need local train service to allow for the long distances between stops you want on high-speed steel-wheel on steel rail systems. And, while there are alternatives with significantly higher acceleration/deceleration performance, they are not quite practical or use a lot more energy (Maglev could allow for frequent (100km @ 1000km/h top speed) stops, but it's extremely expensive to set up and there is basically no way to evade obstacles).
These medium-speed tracks are old, but they allow up to 160km/h regularly if converted to ETCS (I think they need Level 2, due to the increased breaking distance), that is, with the normal regional trains introduced in the past few years.

Even our correct beliefs are not learned through their correctness, but monkey-see, monkey-do.

e.g. highschool mathematics

But some people - communities of people - pored over this stuff for centuries to work it out and try to find flaws (and found them). You could have an AI that tries to find flaws - provided you have an actually correct statement of the problem.

That's the classic scifi problem with robots: they do what you tell them to.
That's interesting. Does anyone have a further source or description of that behaviour?
At this point it seems meaningful to describe behavior as "evil" if it's relatively easy to identify that your algorithm is working badly or producing bad/dangerous outcomes but still leave it running as-is. Do small scale tests until it's fixed instead. Driving cars is dangerous as-is, it's not going to be great to send thousands of people down residential roads that might be less safe than arterial roads AND make them drive worse by frustrating them with bad traffic.

I share your experiences with Google Maps and Waze giving me bad or actively dangerous directions. I learned to distrust those apps as a result.
A cousin of mine only eats "white" food: pasta, potatoes, bread. They've never knowingly eaten a vegetable, or anything green or yellow. They're now in their 40s and still one of the most vibrantly healthy and energetic (appearing) people I know.

Edit: This is NOT a recommendation, nor intended as a diminishment of the suffering alluded to in the article. I just find this relative's bad diet and excellent health an interesting curiosity. They do eat chicken and eggs also, but not the yoke of eggs.
The sponsors are a business out to make money, not to make sound ethical decisions.

The way capitalism is supposed to work is that consumers (the capitalist synonym for “people”) avoid companies they don't like for whatever reason. The problem is this assumes consumers are reasonable.

The sponsor has little to gain by doing the ethically correct but publicly outrageous thing and standing by the innocent person, because there are more people in the angry mob than there are who would reward the sponsor for their sound ethics.
Seems like an outlier to me.
Waze and Google Maps tend to have bad/outdated data and tell people to make illegal turns. The roads near my apartment changed over a year ago and I still see people make illegal left turns (including Lyft drivers unless I warn them about it in advance).
What do you think I assumed?

DanBC's comment cleared it up for me, he has a mental illness, not biological intolerance. I was interested in what happened to him, and how common it is, as I personally know somebody who knows that she's not eating healthy (to the point of vitamin deficiency), yet she still doesn't change her diet. Also she isn't mentally ill.
Yeah I agree. But it is an extraordinary thing to observe over a lifetime.

More accurately, it's only there because it does, in fact, matter to some people. But that's true of every way of expressing any difference of meaning in any communication medium.
