I don't know why Tesla is so focused on self driving in cities. Seems like a far better use of time would be to get to level 3 self driving on highways (which is what other automakers seem to be trying to do). That gets you most of the benefits of self driving (not having to pay attention for long trips), with probably 1% of the complexity of city driving.

Getting city driving working just seems so impossibly hard, there is no way you are going to be able to use ML to determine road rules since they vary by jurisdiction and over time, and there are so many edge cases you won't have enough data for. But how do you write a program that can read a street sign, interpret it's meaning, and act upon it safely?

Even if Tesla just got autopilot to the point where it could be level 3, where drivers don't have to pay attention, that would be a massive improvement, and so much easier than FSD.

Maybe they painted themselves into a corner though with all Elon's blatant lies about FSD, can't stop development without a lawsuit. They seem kind of screwed anyways, looks like they are running into the limits of the current camera positioning and onboard processing power, might need to do another iteration of replacing every FSD owners hardware.

I watched the actual video. The mechanic, who previously worked at Tesla, indicated that brass would handle the coolant just fine; a friend of his had been driving the same fix for quite some time.

A close friend has been taking 4-7 grams of it daily for 7 years. She originally got on it to quit opioids, which worked, but yes she’s now “highly” (heh) dependent on it. Although there are likely much worse things to be hooked on, she says the withdrawals of attempting to get off were unbearable. On the bright side, her career growth in tech has gone through the roof since she started taking it as she claims it helps with her social anxiety, though causal or correlated is anybody’s guess. Would proceed w caution.
Right to Repair explained in under 60 seconds
The lesson we should really take here is the power of wishful thinking. People dearly want to believe in FTL travel. Without it, the Universe just seems so vast, empty and distant. The truth is it is and it isn't. It's only really that on our current time scales.

Not to be a broken record (there's some new variation on some old idea like every week it seems), but I'm firmly in the camp that believes FTL isn't possible. There are two prongs to that.

1. Theoretical: a lot of these theories rely on people not understanding the domain of a function (eg plugging in negative mass or energy into an equation; just because a function can operate over real numbers doesn't mean real numbers are the domain of that function); and

2. The macro evidence in that if FTL were possible it makes it that much more unlikely that we haven't detected starfaring life. Specifically, the potential volume of spacetime goes from a line cone of several million light years to the entire Universe (not just the observable Universe). We don't know how big that is of course but it's may orders of magnitude larger.

So this paper tries to "solve" the negative energy/mass problem. I honestly can't speak to the soundness of this idea. I am however skeptical.

IIRC that's not actually pluralization, it's more like "and the rest of the group".
That conjecture is one of the two foundational principles of relativity - that the laws of physics are the same in all valid frames of reference. "Violating causality" means that in some valid frame of reference A, event X caused event Y, and in some other valid frame of reference B, event Y caused event X. The laws of physics cannot be the same in A and B for both of those to be true.
> There were four versions of the game released: White Label, Blue Label, Green Label, and Red Label, in that order. Each release was a circuit board with the compiled code split across a number of different ROM chips, also referred to as 'ICs'.

Pedantry: Assembly code is assembled, not compiled. I believe I'm losing my personal war on this, and someone here will certainly try to equate the simple mnemonic->opcode substitution and 2-pass label resolution an assembler does with the more complex and in-depth code emittance a compiler does, but it still grinds my gears.
I said started with, not continued to be exactly that. Of course new drugs and treatments have come out since.

Many other drugs/treatments can also be really bad! I'm on some pretty bad drugs myself right now (not cancer related), and wish other options existed here too. Cancer isn't the only area of medicine where I wish I was born hundreds of years in the future!
That’s what I was tongue-in-cheek referring to
There's no absolute coordinate system in space, so there's no way to "stop". You can only change your velocity relative to some other object, e.g. your past self in the example. What counts is acceleration / deceleration.

Slowing down to reach the speed of light might be as hard as speeding up to reach it; I remember it played a role in the theory of tachyons, hypothetical FTL elementary particles which could not be slowed down.
I saw the Anki being demoed during WWDC 2013. At first, I was intrigued but the price turned me off. I couldn't find a justification in getting one especially when Oculuses were competing for my $$$. I generally agree that toys do have their purpose. Those who are involved in AWS DeepRacer competitions can probably attest to that.
The paper also gives recommendation for a starting point for some finite element modeling and optimization for field configurations requiring less energy than that, improving other properties and such. (FEM modeling to search the irrotational sector of the Hamiltonian constraint...)
They mentioned this with a fair amount of enthusiasm - sounding like there may be room to optimize.

I wonder what the gradients look like.

(I was under the assumption that all leases had to have full coverage auto insurance before you even signed the lease? And yes--on most insurance policies road hazard insurance is extra, but just assumed on a lease it would be included. I still remember the battle axe who kept questioning me over a broken windshield. She wouldn't shut up, until I mentioned CA has an Insurance Commissioner.)

>It'd be able to enter warp once.

...why once? Are you assuming all matter+antimatter is destroyed in the single trip? If you have x amount of critical material, could you not warp for half the distance of the "fuel" in your "tank" and then come back?

IANAPhyicist. I'm assuming that if we have the ability to contain and harvest energy from a matter/antimatter reaction then we also have the ability to stop it & start it at will.
As others have said, being bored at work is extremely stressful. I am on the verge of leaving a company where I'm totally bored, for an early stage startup where I will be put to the grind. Oddly when I was in such a job before I had the energy to do other projects. I made the time. Now I have the time but it seems.... Meaningless. I am a developer who codes for fun as well, but in the last year I have not written any code worth talking about. My job is a joke because of how badly organized the company is. I went to therapy, tried to see if I had ADHD because I was slowly sinking back into my old habits of jumping between tasks and not prioritising work. Ultimately I decided I need to leave the company because it wasn't me. I was a bad cultural fit because I'm a person who does things for fun. Work was not fun. It was killing me.

I'm arguing this legal framework, not saying that's how it currently is.

>>It may have a more direct impact, but that does not mean they will have better outcomes. For one, you will be taken to the nearest hospital in an emergency - you have no choice.

Only 8% of healthcare spending is on emergency services, which can and should have government involvement to avoid abuse of geography-based monopoly by service providers.

But the remaining ~92% of healthcare spending is made through non-time-sensitive decisions where an individual has plenty of to assess the market options.

>>Most people do not possess the level of knowledge to evaluate a medical professional and the information given to them by that medical professional.

Just as people delegate this analysis to a cadre of politicians in the current monopolistic system, people would be able to delegate analysis to reputable experts in a free market.
I think data-races that can cause undefined behavior are limited to maps and slices and other structures that internally use unsafe.

It is interesting how nbc news now sells geopolitical opposition to China by pointing out that unifying Taiwan is part of a plan to “make China great again”.

That's not an agreement that it actually is hackish.
Ya, I think its mostly an incentive thing. Software just isn't use to doing BOMs (though certainly lots of B2B sales have something like BOMs changing hands). The incentives just aren't there for this to happen without some sort of push.

I honestly don't quite get what their product does from their website but is it just me or does allowing "non-technical operators and anti-money laundering (AML) teams the ability to “easily” write complex statistical models and deploy customized workflows" sound like a bad idea?
Correct. In a bit more detail:

Here's the grid coordinate system for the streets in my town. One intersection is (0, 0). But in the grid system used by the next town over, that same intersection is (100, 200). And that's fine - we're just shifting the origin, which changes all the numbers.

The same thing happens with velocity. If I'm on the ground, "stationary" means that you're not moving with respect to the ground. If you're in an airplane, "stationary" means that you're sitting in your seat, and you see me on the ground moving toward the back of the plane at 550 MPH. And that's still fine - we just shifted the origin of velocity.

Light is unique in that, when you shift the origin of velocity, it's speed is still the same number. No other velocity transforms that way.

(Well... light isn't quite unique. The speed of light is unique in that way. But gravitational waves also travel at the speed of light.)

I'm pretty sure the combination of those two is 90% of the "cyclists don't obey the law" meme. When a cyclist breaks the law they make the whole out-group look bad, but a driver who breaks the law is just "one bad driver."

Maybe “autopilot” then (as in the Tesla marketing term, not as in a real autopilot)? /s

Both lull you with a false sense of security which will suddenly and unexpectedly cause you to pay dearly for using it. Interestingly both seem to also get a vaguely similar balance of critics, apologists, and advocates on here.

No, I'm merely pointing out that

is no weirder than the certain portion of the internet that needs to criticize Musk at all times. In fact, the people that feel the need to interject criticisms of Musk into conversations that aren't really about him clearly have Musk living rent-free in their heads to a greater degree than the defenders do.
A big problem with radar was the resolution. The radar signature of a highway overpass looks extremely similar to the monorail column.

Emergency breaking on a highway when going under an overpass is also a huge problem, so radar may not be the answer.
They still do something similar to this. It's awful for the paint of your car, and quite dangerous on a motorcycle.

I don't collect antique furniture, but I do cook with and maintain 100-year old cast iron and a very nice German chef's knife.

I think the biggest difference between software maintenance and maintenance of most physical objects is that physical maintenance is calming, tactile and pleasant.

Routine software maintenance, on the other hand, is hacky, frustrating and stressful.

I would much rather sharpen my knife on a whetstone than fix a dependency on a CI server or wrap my head around Apple's latest code signing bullshit.
> I'm presenting temp/humidity numbers that are reasonable for where I live (NYC where the summers still are pretty hot and humid)

NYC, while it does get fairly hot in the summer, is actually not very humid compared to South Texas or South Florida.

> you're dehumidifying down to 45% RH -- my consumer-level heat pump doesn't even have that option

A typical home A/C system (not heat pump, just straight A/C) in South Florida or South Texas will output a dewpoint of around 50 to 55 degrees F. (I used 12 C = 53.6 F in my heat transfer calculations upthread.) That's significantly lower than the typical dewpoint output of a heat pump (different working fluids, hence different temperatures at the indoor heat exchanger).

> The urban poor is probably a lot more numerous than the rural poor

Actually, the suburban poor trump both urban and rural poor by far. That is, people who live in communities not in the urban core of a metro area, but within distance of one. They are much more attached to cars than the urban poor (who can't afford the parking fees anyways). These are the people stuck with crappy 1 hour commutes to their low paying job, whereas the urban poor...they are close enough to their jobs, but instead their housing is really expensive (or of bad quality). The suburban poor own a car, parking isn't much of a problem for them, and they make up a lot of the cars on the freeway during rush hour because their jobs provide them with much less flexibility in avoiding it.

The suburban poor might even own a cheap house, they are much more numerous in the USA than who I would consider rich. So think someone who is commuting in from Concord because they can't afford to live in SF, not those people living in SF itself. SF is generally a bad example because of parking costs (you can't afford to drive there), but outside of downtown there are still lots of jobs that people commute by car to. Here in Seattle, a lot of people drive to their jobs outside of the city core, coming in from outside of Seattle to do so (whereas people like me take the Google bus, my Amazonian wife just has to walk a block to the bus stop that takes her within a block of her office, because we paid a bunch of money for a place in Ballard).

The "plasma-powered flying saucer" in your article doesn't appear to have any relationship to the thruster in the original post other than the word "plasma". The former appears to be an air ionizer [0]; the latter is a repurposed fusion research tokamak.

Everyone always talks about FTL travel for spacecraft, but there's also an interesting perspective from weapons side (and this a reason to be a bit careful and think about some ethics as we move along). A FTL kinetic weapon would be devastating. If it comes with a collapsing warp bubble then there's basically a gamma ray "gun" that travels right in front of your mass that is traveling at tremendous speeds. You look at impacts on the ISS and you can see how much damage a small object does[0]. This is also especially important when trying to develop such a device for travel as you'll probably be sending small objects before a spaceship, or rather a "bullet". Where that object ends up may be in serious danger.

Edit: And as others are pointing out, communication. There's a whole slew of technologies that could be improved/invented if you can move things/information FTL.
