Nonsensical long ago debunked racist propaganda, bob.
They tried that excuse at trial, it failed. It was bullshit then, is still now.
More liars lying.

Only one innocent man here, the one being framed after his murder….Floyd.

You are so gullible. There’s a reason you can only find this on “valuetainment”, a no facts needed far right internet propaganda site that’s steered you wrong multiple times before. You never learn. You’re never embarrassed at how many times this type of insulting lie falls apart. You still think you’re going to get away with it THIS TIME….never works out…your optimism in the face of so much failure is impressive though.. Such nonsense.

I love your optimism.

Professional economist here (hence, perceived as right wing) who began studying economics due to concern about climate change (hence, perceived as left wing).

[1] The classic statement of when markets 'work' is the 'first fundamental theorem of welfare economics'.

[2] 'work' in this sense means 'leads to a Pareto-optimal outcome', which means an outcome in which no one can be made better off without making someone worse off. This is a low standard: an outcome in which I have everything is Pareto-optimal.

[3] the conditions for the welfare theorems are generally not satisfied in practice. Here, as alluded to in the ad, carbon emissions are 'externalities': if an oil company sells you gas, which you then use, both of you are better off, because you're assumed to have taken into account the effects of your exchange, and decided to proceed; other parties have not, so may be worse off.

[4] in general, failure of the welfare theorem conditions isn't enough to make the case for government intervention: the outcome may still be 'constrained' efficient - meaning that, given the inherent constraints in the problem (e.g. asymmetric information), the market outcome is Pareto efficient.

[5] again, even if it is, you may not like the particular constrained efficient outcome the market yields (e.g. I get everything).

[6] in the case of externalities, the theory is pretty well established - if we want efficient outcomes, we need to align the private and social costs. There are two basic market-based tools for doing that: quantity tools (e.g. carbon permits) and price tools (e.g. carbon taxes). Which performs better depends on the sort of market imperfections.

[7] obviously, we will never have a perfect estimate of the efficient price or quantity of carbon to emit in a given year. Equally obviously, to me at least, this is a classic case of an externality with a well developed body of theory pointing in the direction of some level of controls.

[8] in my experience: people familiar with the economic theory tend not to be 'pro-market' or 'anti-market': they tend to want to understand how the market can be used to deliver societal objectives and, when it can't, how to correct its imperfections.

I would like to see this succeed, and after seeing this video I have a bit more optimism, but it's still a lot of hurdles to overcome. And if they have an accident (release timing error > 1ms), will do major damage to their launch chamber, probably taking months of repairs to recover from. Whereas SpaceX is almost proud of their rocket failures...

I was pessimistic a few months back, after seeing Thunderfoot's "busted" videos about Spinlaunch: https://www.youtube.com/watch?v=9ziGI0i9VbE ; https://www.youtube.com/watch?v=ibSJ_yy96iE ; but his analysis is much more "armchair" whereas Brian was actually there on-site and has more (previously unpublished) information.

Scott Manley also did a video about it: https://www.youtube.com/watch?v=JAczd3mt3X0&t=4s
but it's more of a "how it works" and has a lot of overlap of info with the above Real Engineering video.

Full episode..

In this episode, I describe a comprehensive toolkit consisting of behavioral and supplement-based tools that you can customize to enhance the quality, duration and impact of your sleep. This has an enormous positive impact on your overall health and daytime functioning, brain, hormones and immune system. I teach you how to effectively harness light (and darkness), temperature, food, exercise, caffeine, supplements, and digital devices in order to fall asleep faster, stay deeply asleep longer and overall, and achieve better quality sleep. I also describe how these tools can be modified to recover quickly from a poor night’s sleep, jet lag or bouts of shift work. Given that sleep is the foundation of all mental health, physical health and performance, this episode should benefit everyone as it provides an essential toolkit of science-supported, low- to zero-cost strategies that can be tailored to optimize your sleep routine.

It dropped precipitously because Elon was buying Twitter and would have to sell billions of stock to pay for it, just to name one self inflicted wound. The economic state should benefit Tesla, as you say, with gas at $5 and rising, ev’s are in high demand.

Gas in Canada is $6.75 US. UK is $5.75 in usd. Europe is around $5.25. But sure, it’s all Biden’s fault. Meanwhile my Exon, BP, and energy mutual funds are reporting record profits….but there’s no correlation. Hmmm.

I guess you didn’t hear Elon decided to cut his workforce by 10% anticipating a slump in sales. Elon doesn’t share your optimism.

Isn’t his major production hurdle a worldwide chip shortage, which he can do nothing about? Not sure how he’s going to ramp up production without more chips.

China isn’t the only economy in trouble….where is this unsold production supposed to go? Europe?…in trouble. US?… looking like we’re in trouble and a logistics nightmare. How much does shipping add to the price too? $5k? More?

All car manufacturers raised prices multiple times last year significantly, they all have a shortage of chips. I think it’s more likely he raised prices because he could without slowing down sales, not in order to slow sales.

Granted, ev’s are in high demand, but the big 3 are ramping up production and will outbuild Tesla in short order, as are European and Asian companies. He’s done great without competition, but some real competition is coming. The electric F150 is going to produce around 15000 this year with over 120000 (edit now 200000) reservations. They built a billion dollar factory for it alone, it will be the best selling full sized ev truck as soon as production starts. They also won’t have a chip constraint because they can take them from their huge f-150 supplies to meet production estimates.

If you want Tesla stock it’s not the worst time to invest, that was last November, but I certainly wouldn’t go all in. The PE ratio is still near 100….GAWD AWFUL. That’s called a speculative bubble….they pop. Ask Twitter.


Sorry about your dad. Mine died when I was 21. It’s never easy.

Eternal optimism incarnate.

Using a mountainside might help with structural integrity, but it's not likely to give much air resistance advantage if I'm reading the math correctly. The 5 highest peaks in the US are all in Alaska and and range from just under 5km to just over 6km. Commercial jets using air resistance/density for lift fly at about 10km and even at 38km aerodynamic lift still carries 98% of the weight of the plane (https://en.wikipedia.org/wiki/K%C3%A1rm%C3%A1n_line)

Air density is halved at 5km compared to sea level, but air resistance doesn't diminish as quickly (due to it being multiplied by velocity squared and drag coefficient), and only becomes irrelevant (for short-term purposes) around 100km at the Karman Line.

If we had a 5km peak in Florida, the lack of logistical costs might make the benefits worth it, and if we could build on one of Equador's 5km peaks, then there's the further advantage of equatorial location for optimal rotational advantage (part of the reason we launch from South Florida)

a very clear example of an optimal stopping problem

I'm an Apple hater. I hate its business practice, greed that's way above and beyond the norm, hubris, closed eco-system, terrible OS, dumb/outdated design (but marketed to shit as "intuitive/elegant") on and on I can go, but one thing I can't fairly hate is its hardware build and material.

I don't see much wrong (other than "not optimal") with the heat sink/fan distance here. The way the fins are aligned do allow air flow to direct to the fan. Takes a fraction of a second to generate the wind tunnel effect, and all the components between the fan & heatsink just need to be able to withstand the heat, and they surely do.

It's easy to see why they do it. That's "height". Apple want to make the Air as thin as possible, they can't do that by stacking 4 components together.

I work in IT. I troubleshoot and optimize incredibly complex systems using a wide range of toolsets. There is zero chance I could make something like this work without trashing my house in a frustration meltdown.

[T]hat is not the America I know.

The America I know is full of courage, and optimism, and ingenuity. The America I know is decent and generous. Sure, we have real anxieties—about paying the bills, protecting our kids, caring for a sick parent. We get frustrated with political gridlock, worry about racial divisions; are shocked and saddened by the madness of Orlando or Nice. There are pockets of America that never recovered from factory closures; men who took pride in hard work and providing for their families who now feel forgotten; parents who wonder whether their kids will have the same opportunities we had.

All that is real. We’re challenged to do better; to be better. But as I’ve traveled this country, through all fifty states; as I’ve rejoiced with you and mourned with you, what I’ve also seen, more than anything, is what is right with America. I see people working hard and starting businesses; people teaching kids and serving our country. I see engineers inventing stuff, and doctors coming up with new cures. I see a younger generation full of energy and new ideas, not constrained by what is, ready to seize what ought to be.

Most of all, I see Americans of every party, every background, every faith who believe that we are stronger together – black, white, Latino, Asian, Native American; young and old; gay, straight, men, women, folks with disabilities, all pledging allegiance, under the same proud flag, to this big, bold country that we love.

If you need it to sound more like Trump, just pretend in the middle somewhere that he said he wanted to kill a hooker and feed a dead cat to an ATM.

When I hear the easily recognizable voice of the narator on this video I immediately turn it off. It seems every site that uses this narator has the same M.O. Lots of non relevant or misleading stock photos and endlessly bloated verbiage. I guess they are trying to match the YouTube algorithm for optimal video length? I find it quite annoying.

Lack of flexibility, perhaps, but exceeding your sales projections by so much you can't keep up and have to outsource from competitors could be a genius (or moronic if it backfires) marketing move....if Tesla power packs outperform ones purchased from competitors in an apples to apples comparison (but one designed to favor Tesla from the start because they are in Tesla cars, optimized for Tesla batteries), they end up selling exponentially more when the new factories catch up and make a surplus. Worth it if in 5 years competitors all start buying from him.

Why is everyone losing their shit over a port of a poorly optimized game to a newer version of the engine?
