"I never said that. Please don't make up strawmans."

That's not a strawman, that's the definition of zero tolerance policies in schools - both parties in a fight get punished the same.

"And by your reasoning, then bullying shouldn't exist today because the school policies should prevent it, yet it's more rampant than ever."

'I never said that.'

What you did say is that victims can't solve bullying and that school policies should. What we clearly see is that bullying is a growing issue under zero tolerance policies because the victim is given disincentive to defend themselves - it becomes a vicious cycle that protects bullies. It also is at odds with my personal experiences.

If the zero tolerance policy isn't the school policy you were speaking about, then what is? You imply that school policies should prevent bullying, but we clearly don't see that.

"Funny how I only hear the 'stood up to bullies succesfully' story and never the other ones. See my other comment."

You do hear of the other stories - kids committing suicide or shooting up a school because they are trapped in a failed zero tolerance system that leaves them with seemingly all-or-nothing options. You also witness kids just "taking it" if you are observant enough.

So far you seem to be just trolling - offering neither arguments nor facts that support zero tolerance systems or refute the facts that I, and many other on here, have presented against those systems.
Hi folks,
I am working on a product that makes usage-based search possible. Our first listing is for tablets.

The problem we are trying to solve is helping people decide what electronic products to buy based on their usage.

Electronics products can be tricky to buy, especially to non-technical people. They end up buying expensive ones just to be sure and end up not using most of its features.
Please let me know your feedback. Or just upvote if you like the idea.
Thanks in advance!
They must win back the process advantage. It's existential for them, and important for the U.S. geopolitically.

Their fabs need more customers to justify the astronomical investment. They must expand their foundry business.
Mind controlling the people via the internet seems more urgent
Seems to be a capital intensive business with no clear path to commercialization.

The robots developed by ABB, KUKA, Mitsubishi and similars are very different to what Boston Dynamics is trying to build.

These are impressive robots but their utilitarian value is too low. An industrial robot by ABB with a clear use case in a manufacturing process costs like $80k. An impressive toy robot with no clear use case like Boston Dynamics’ Spot also costs $80k.

If these robots had a clear use case besides carrying heavy stuff, BD valuation would be 5X or 10X their current valuation.

Of course the real value would be to use their research and know-how on these type of high-mobility/low foot-footprint robotics into actual industrial settings and use cases.

Google didn’t have any internal use case for this tech and commercializing the technology as a vendor is way out of their competence and probably not enough value there to justify extra investment in sales, supply chain, etc.

SoftBank was just doing what it has been doing for the last decade which is investing in shiny things.

Hyundai may be the first owner to actually have a clear use case for this tech.

I think phantom braking with TACC is a function of it being alpha software. With the beta stuff (everything else), the driver is expected to always be alert and intervene where appropriate, so Tesla doesn't have to be as aggressive on the safety side.

As it relates to the features, I agree that they aren't ready for what most drivers expect, either because they aren't reliable enough (beta) it because they aren't confident enough (TACC). With that said, FSD is a feature set, not a level of reliability. As a whole it eventually needs to reach a level of reliability, but there's no specific time horizon.

For Tesla, a feature moving from beta to alpha is what indicates reliability. In addition, that reliability may not come with the degree of confidence most people expect from a driver. Safe FSD could just end up as the AI equivalent to a student driver. It'll get you someplace safely, but there may be phantom braking, excessive waiting, and so on. If that's the case it would be nice if we could enable a beta version with more "normal" driving that we would have to keep an eye on.
And their supply chain, but now we are at everybody anyway.
Two thought triggered by this article.

1: What alternative designs for quadcopter would be viable for small drones? Some lighter-than-air quality? I assume the complexity involved in making a helicopter collective would be too heavy. Is it really quadcopters all the way down?

2: Why not smaller? Would an even smaller drone be unfeasible due to battery weight and square/cube law issues? What's stopping us from gram-scale drones? Presumably the interaction with the air would create new problems and things to take advantage of.
It's interesting how in manufacturing (and other industries with lots of automation) we are trying to move away from humans as much as possible, while Boston Dynamics is trying to replicate humans as much as possible.

Of course there will always be cases where we want to send a robot into an environment designed for humans (ex. firefighting) so there is value in humanoid robots, but it's interesting to me that we are going in two completely opposite directions with robotics. Imo humanoid robots will have some limited uses, but ultimately not be as useful as robots built for specific tasks.
Be as snarky as you like. What have you contributed to the field of CS that's so much more impressive than the Professor?
Can you fill me in on where the levels of Tesla software are? The version of the OP who you are calling out as "apples" (the old, legacy one), what SAE autonomous level is that one? And the "oranges" one that is new and beta, is that a different level? If so, which level?

* Level 0 (No Driving Automation)

* Level 1 (Driver Assistance)

* Level 2 (Partial Driving Automation)

* Level 3 (Conditional Driving Automation)

* Level 4 (High Driving Automation)

* Level 5 (Full Driving Automation)

> Beyond all this, without understanding the underlying cause of the behavior you mention, it's hard to say from a risk perspective if the car made the right choice.

What argument could there be that suddenly slowing down on the freeway with no visible obstruction is the right choice?

It does not avoid any danger, but it creates a danger of getting rear-ended by cars behind you.
> This really be true. So much of the certification Ive seen are bogus nogus even high schoolers can figure out. I suppose the software world cares less about looking good on paper and more about practically writing software of good quality/creative work.

The software world cares less about building things that actually work reliably, compared to other engineering professions. It's accepted and sometimes even celebrated that software will have serious, preventable defects (e.g. "move fast and break things"), in a way that's not so in many regulated professions that "build things."

I'm not sure I agree with your comment. While I would be willing to concede that witnessing the visualization of violence might have some kind of affect towards increased desensitization, that's not necessarily a negative.

In some situations being able to keep a cool head in a crisis or in an area where something like this might occur could actually prove to be a benefit, as you are less likely to enter a panicked state (such as working in an environment where you may witness excessive amounts of blood/gore, eg paramedic)

I think that the vast majority of people (teenagers included) are more robust than we give them credit for, and can distinguish fantasy from reality.
We have to pull manufacturing out of China until something changes, then. Each and every one of us is indirectly contributing to slavery until then.

>Checksums will identify something went wrong, and then you need to redownload the file to a quarantine network and scan it. Takes time.

Surely a sensible file transfer algorithm would compute checksums on small and easy-to-retransmit chunks? Does rsync not do this? Isn't it already happening in TCP?

It makes it so that people don't have a strong sense of what a healthy version of themselves is, and can assert that they must be healthy "as they are".

I've found Body fat % to be a more useful number, it's easy to understand what you'd look like with 10% less body fat - and you won't see many/any athletes with 30%+ body fat. When I first started tracking this I was shocked by the initial number (35%) and managed to work it down to 17% over time, my total weight didn't change by more than 5%.
The military leaks did shed light on (possible; there is dispute in the international community) war crimes, and had Manning only leaked those specific videos, my opinion would be very different.

The State Department cable leaks were grossly irresponsible, as were most of the rest of the military intel leaks. She slurped and dumped without understanding of the ramifications of divulging all that information, which can endanger her fellow soldiers in the field, who had not committed war crimes. That she appears to have gotten lucky and it did not, in fact, endanger soldiers in the field is irrelevant to the reason such a slurp-and-dump is a court-martial offense.

I think reasonable people can disagree on whether, in aggregate, she did more harm than good. She shed light on (what we would want to be) senseless deaths of several civilians in a military theater, and separate from that, she catalyzed multiple revolutions resulting in the deaths of hundreds.
False!

Unhealthy people are great for saving money. Health care costs are disproportionately skewed towards end of life care. People who are unhealthy die younger and more quickly.

Subsidizing domestic sugar production by spiking the price of sugar... means less sugar consumption. What's the joke?
It also depends on the person. We are all individuals with millions of different variables contributing to our behavior, some genetic and some environmental.

In my opinion it's math not python which got the matrix multiply operator wrong. It's not commutative so it shouldn't be written with the same operator as the regular product. It's abuse of notation again from math notation.
They don't let him talk about manufacturing? That makes no sense. Though I guess he's just reverse engineering the rules so it could be some random thing he's mentioned a few times when discussing manufacturing that YouTube takes offence to.
Sure but even then, those groups could use these long-ranged and relatively cheap drones to deliver all those horrific weapons. Huge rockets and such is fortunately prohibitively expensive and hard to manage. Whereas drones compared to rockets, are much cheaper and easier to manage could easily substitute those rockets and they would also probably be able to evade our defensive systems. For example, Turkish drones destroying Russian anti-air defense in the Armenian/Azerbajian war.

> It's not clear that the transition from low quality to high quality full self driving will be linear. Most claims around anecdotes come with an unspoken assumption we ought to see steady improvement over time vs a step-function like behavior. The latter seems somewhat possible given the nature of how improvements in AI systems seem to happen.

That is true, but it's actually an argument _against_ the assumption of full self-driving capability being just around the corner. Because that assumption itself is based solely on observed recent progress, which - as you correcly state - can be very misleading when used as a means to extrapolate the future due to the tendency of the AI field to have long stretches of very little to nearly no progress at all, divided by huge leaps followed by stretches of very fast progress in specific sub-areas of the field. We clearly have seen such a stretch recently, triggered by the deep learning idea and enabled by an explosion in parallel computing capability over the course of the last decade.
I've only ever visited San Francisco in the US, and the first time I was there I was slightly surprised that in terms of obesity it seemed pretty similar to Dublin (which wouldn't be the thinnest city around, but is middle of the road European). Then I flew back via O'Hare, and really saw the difference when waiting for the transfer; quite dramatic levels of obesity.

I wonder how much of it is just down to urban Americans walking places, and rural and suburban Americans less so.

I did also notice that there was added sugar in virtually _everything_.
Not just that, but even if you cook it yourself, it can be hard to find certain things that are healthy, almost everything has added sugar, or sugar concentrates for example, and a lot of produce are adulterated and so arn't even the real thing, like some Olive Oils.

You don't actually have to touch the pavement. Deep, aggressive, self-clearing tread seems to be enough. I put an ice spiker pro on my bike and slush goes from ice rink to no big deal, whether or not I touch pavement.

I speculate most snow & slush under compression has some shear strength to offer even though there is little dry friction.
Interesting idea to fill a drone with helium, then presumably it could have smaller motors or longer flight time.
Mcdonalds has chicken burgers.

The cheapest chicken sandwich at McDonald's is slathered with mayonnaise. Of course one can specify that the mayonnaise be omitted, but then one is confronted with the fact that the factory-made chicken patty is fairly unpalatable by itself.

The main question about Subway is which is more disgusting: the food or the way they treat (especially immigrant) franchisees? I can't think of a single item at Subway that qualifies as "cheap" either.

Non-millionaires who seek tasty and healthy food must learn to cook.
OT, but "Long-distance trails in the United States" is a great example of how Wikipedia lists tend to spiral out of control. It includes "long distance" trails that go down to a 26 mile loop trail around a lake.
I second this.

The Washington Post usually has quality content, but this one is disappointing. If you look at the author's history of articles, it's one post bashing Apple after the other (looks like there is an audience for it).

Nice approach! Reminds me of studying finite state machines many years ago in school. Do programmers use these diagrams in designing their code? I would think so. I have found using a state approach especially helpful in processing streaming data.

Yes American outlets are already more dangerous than European style; when the switch plates are missing there are exposed live contacts on the sides.

I don't know why but it stood out to me how many houses (of friends) I saw where all the switchplates were gone. At some point maybe they're removed for painting/wallpaper, or they just break, and either through a lack of money or lack of motivation never get replaced.
> braking is more evenly distributed among the 4 wheels since the drive shafts are locked.

There is something seriously wrong about either my understanding of how cars work, or yours.

I have brake disks and brake pads on all 4 wheels of my (FWD) car; pretty much every car does. How would a drive-shaft help "distribute" braking power? The limiting factor here isn't the force each brake can exert on their wheel (they're pretty much always able to lock up), it's the traction between the wheel and the ground (the tire).

In my mind, an "ideal" emergency braking scenario would be all 4 wheels braking at the maximum force they can without slipping, and that can be done much better by the ABS system when they're all disconnected from each other. A driveshaft connecting them would be irrelevant at best, but more likely it's a nuisance.
Why does Tesla bother with radar and ultrasonic sensors? Humans can drive without them.
That's because of the energy density (per mass) of Li-Ion batteries. You basically hit a wall at 20 minutes that's very hard to push past (it almost feels like a law of physics).

But maybe they're using non-rechargeable batteries: zinc-air or lithium-iron-disulfide (ie. a 'lithium' AA battery) or something else? Trade offs are different for military.
I just reviewed it and somehow I missed that detail that the inflection point was way before the second vaccine on the first reading. Very interesting.
> Nobody seems to know what the solution is

Allow me to represent the predictable tech-bro YIMBY perspective: we don’t build enough housing. Supply has lagged behind demand for decades. And still basically everybody opposes new housing near them.

If “we don’t know the solutions” means “we don’t know what is causing this,” then I think that’s wrong. We definitely know. But if it means “we don’t know how to change course,” then that’s clearly right. It’s a disaster.
Obesity is 100x worse of a crisis than covid. We do nothing to change obesity or the lifestyle choices that lead to it.

We need to have a national dialog about obesity that results in some people feeling bad.

Global levels of obesity are set to meet US levels by 2040.
Anecdotally, I'm aggressive because I'm French and Irish. ;) Doom and Quake didn't change that. Never was in a fight in school (I was too big and quick for anyone to chance it).

Different features of Tesla's software have different levels. As a whole, it's level 2.

If you restrict it to certain parts of driving, eg TACC, that might be level 4 (doesn't conform to the chart though). It can handle everything in it's domain, albeit in a rudimentary way, so a human doesn't always have to shadow it, but they do need to be ready to take over in some cases.
Hmm, that makes sense. From your username I suspect that you may know (much?) more about this than me. :)
Thanks! This will definitely take a while to parse :) Appreciate the link!
Because it forces people to confront the reality of their obesity and how out of shape they are.

Because of our hearing loss we haven't trained our brains to filter out noise the same way people with normal hearing have since birth. So it might be possible to train the brain, but the only way to do that is to feed more sound to the brain.
Prove that what I said is bigotry or "implicit subversive racism". I chose a recent, controversial event illustrating an influential media company -- The New York Times -- doubling down on costly mistakes made in the name of social justice. The heterodox thinkers of the Times will move on to the Substacks of the world where their critical reasoning skills and rejection of cult membership make them even more valued.

No bigotry or racism here.
