Rocket engines shouldn't be that cheap to maintain, they are designed to be very reusable, unlike Merlin they were designed for the beginning to be reusable.

The whole reason for the full-flow staged cycle is to have much more reasonable internal temperatures. Methane as well was picked partially because its far more clean burning.

There is no reason rocket engines couldn't be as reliable a jet engines.

> far more fuel

RP1 is very expensive. Methane is much cheaper, and they can even produce it local. Ox is very cheap and is basically gone turn into the cost of electricity and they are using local solar to make it.

Helium is also a very expensive part of the Falcon 9. Starship avoids the use of helium.

Additionally the Falcon 9 used TEE-TAB that is also expensive.

And it used nitrogen as well, that not expensive but just one more thing to worry about.

Falcon 9 has 6 different different consumables, Starship has 2.

> generally more expense in all the ground operations

This is wrong. The Falcon needed to have drone ships operating and tug boats for them as well, to catch the fairing they have another 1-2 boats out there to collect the fairing.

Then the stages need to be brought into port, transported back to the launch site and so on. The fairing have to be refurbished as well.

In additional Starship has multiple design upgrades that make it actually easier. Unlike Falcon 9 Upper stage, the Starship will be fueled from below, meaning there is no secondary fuel infrastructure for the upper stage. Not requiring the fueling of the consumables above also makes it much easier.

Plus they were able to apply everything they learned from Falcon 9 and ground operations to this new launch vehicle and launch site.

> In a world where this can be launched for $2M, Falcon 9 can be launched for less than $1M.

Falcon 9 can not do that. First of all, you need to build an upper stage that cost you 5-10M. You can't build that Upper stage fast enough to reach the required flight rate. Falcon 9 is also more difficult to launch and prep for launch. It wasn't designed to be fully reusable and still need more checks and refurbishments.

Now $2M is extreme, even if it is $10M or $20M that only really matters for stuff like Mars. If you can launch it anywhere under $100M its revolutionary vehicle for space flight.
In a world without quack doctors, this would probably be workable. In a world with them, employers may reasonably want to do more diligence in some cases.

I've experienced something similar. I have a PhD in astronomy, and that tends to attract a certain sort. I became friends with a guy a while back who had discovered a group of geocentrists and was genuinely curious if there was anything to it. He lent me a book he had bought from them that was about 800 pages long making the case for geocentrism.

Now you might think that it's an easy enough thing to prove that geocentrism is wrong. What about the Foucault pendulum? Surely that at least proves that the Earth rotates! But the geocentrists had considered that and a whole lot more to boot. The book was meticulously researched and went through dozens of historical experiments that demonstrate the motion of the Earth and then presented an explanation as to how these results were, in fact, consistent with their geocentric model. Many of these experiments are so obscure that they've pretty much been forgotten by everyone except historians of science.

Of course it was all nonsense, but it was a surprisingly sophisticated form of nonsense. Fortunately for me by the time they were trying to explain away certain results in quantum physics they started to get pretty obviously out of their depth and were making easy to catch mistakes. But without that knowledge, discovering where they went wrong in their logic was non-trivial. I could certainly see how it could be a plausible argument for someone without a background in physics.
At this point you're just arguing semantics about the term "moral value".

But that wasn't even the original term. The first comment in the thread was about whether people are "stupid and superstitious".

So pretend the question was "Do you think what a person reads has no predictive value on how stupid and superstitious they are?"
It does matter. A person with skill has a higher probability of winning than someone without skill. There are two sequential checks... first, the check that the user is not in control of, the "will the game let you win" check, then the "did the player use enough skill to win?" check.

Let's say the game only allows 1/100 tries to have the chance to win. Player A has the skill to win 50% of the time, player B 25%.

Player A will end up winning 1/200 times, while player B will win 1/400.

Skill matters.

Now this is some good insight on why Intel would buy GF. That cross-licensing deal alone I can see being very useful for Intel as they push in to EUV.
weel it's a bad idea unless you update just one package that doesn't have too many shared dependencies, things gets complicated with shared dependencies across their packages, so that's why it's better to run the full -Syu of course not automated but when you know what you are upgrading and possible manual interventions (if any) or caveats that you might have with the changes.
My suspicion is that skepticism has morphed into denialism in general. We’re seemingly at a point where any assertion will get attacked so many times that eventually even chimps on keyboards would come up with a reasonably credible (seeming) critique despite having no deep knowledge of the original point or underlying system.
At least CVS made it obvious that renaming a file wasn’t worth the effort. Subversion pretended to let you and then svnmerge.py took its revenge.
Why not? After the last year and a half plus of them being hailed as "essential" and "heroic" for their "sacrifice" in keeping society functioning during the pandemic

Personally the entire concept of "I own one of the basic pillars of your survival, pay me for shelter" never really sat well with me.

But if we're just making a value judgement on "deserved" I'd think the people who keep society together for the rest of us should get a pretty big seat at the table
I often feel that people take "unit" test too literal and E2E as well. You can write perfectly valid, fast and useful partly integrated tests with common unit testing frameworks.

The other thing is that like you and come siblings have pointed out, many if not most people write unit tests all wrong and in the end just test the mocks. Those are really bad and you can just throw them away. Same with all those tests that just check that the right internal calls are being made. Tests nothing.

You need to attack the "business end" of your unit (or small groups of units). Inputs in and assert the outputs. Asserting that a certain collaborator was called can still make sense but if that's literally the only thing you do it's not very valuable at all.

You can generally see whether a unit test was a good unit test based on the fact that you were able to refactor the implementation of the method _without_ having to change the unit test. Yes, those definitely do exist, even in larger systems.

- paper describes work that was awarded a Nobel prize

If you would be so kind as to identify anything in the 2017 Nature paper that was corrected by a 2021 "blog post" or any other literature, that would be helpful.

The Nobel prize for Ivermectin has not been retracted. The 2017 paper preceded therapeutic debates of 2020 or 2021.
I 100% think this is a gambling game and should be outlawed in places gambling is illegal.

I was only saying that there is skill involved. Gaming laws never classify gambling games as those that require zero skill. Otherwise, poker, blackjack, even craps wouldn't be gambling, because all bets do not have the same odds, and therefore skilled players do better than unskilled.
I was hoping someone would post a score. I got 35, but I kept getting distracted.

The hell is this question? You're the one who equated stupidity and superstition with "moral value"!
Yeah, sorry, I wasn't super clear there. I meant to emphasize the characterization of the content: "at best misleading and at worst outright falsehoods".

Calling it that makes it easy to say it should be banned - but remember that the wuhan lab leak hypothesis was characterized exactly the same way. And that turned out to be acknowledged as plausible and even likely. If you're pro-censorship here, then you're in favor of banning speech about things that could be true and important.

Your argument sounds like: even if the only scientific study that supports its use is fraudulent and wrong, we should look at some cherry picked anecdotes to confirm our preconceived belief that this drug is helpful to patients.

Sorry but this demonstrates a severe misunderstanding of the way medical studies are performed and used in clinical practice. The only way you know a drug is beneficial is to do the study and get the data.

Just so HN readers understand what alternate reproductive methods mean in 2021:

1) US current society is a gynocracy. Their fantasy is to reproduce without men ("I don't need no man.")

2) Women are bragging about being single moms on social media ... if it's a baby girl. Otherwise, it's an abortion.

3) IVF is usually a failure, with 5% or less success rate per implant, and huge bills ($20k to $150k.) Even if the implant takes, it's still considered to be a high-risk "geriatric pregnancy" for women over 35 yo.

The above is what the collapse of Western society looks like.

A systems theory approach is an opposite of a reductionist approach. From Wikipedia ( https://www.wikiwand.com/en/Complex_system ) :

> The study of complex systems regards collective, or system-wide, behaviors as the fundamental object of study; for this reason, complex systems can be understood as an alternative paradigm to reductionism, which attempts to explain systems in terms of their constituent parts and the individual interactions between them.

SpaceX Falcon 9 overall has an incredibly good flight record. They very early had one supplier part they didn't correctly validate.

The other failure (non-mission) was when they discovered a real unkown-unkown about COPV tanks and helium tanks in near 0-kelvin temperatures.

So yeah, they should not have made that mistake, but its also the case that nobody has a perfect record. Considering the errors most rocket companies have made, theirs seem fairly reasonable.

Misleading title.

The study found that the minimum wage isn't enough to afford the average fair market rent for a two-bedroom rental.

Trying to compare average rents to minimum wages doesn't make sense, as anyone earning minimum wage wouldn't be in the market for an average-price two-bedroom rental. It would have been more useful if they had studied something like bottom decile wages compared to bottom decile rents.
Nice to see that the $52bbn in tax money from the chips act is being used for consolidation of industries. Blatant corruption and nobody even cares.
Check out this classic New Yorker article. [1] Here's how it starts:

"My wife and I got married right out of college, in 1978. We were young and naïve and unashamedly idealistic, and we decided to make our first home in a utopian environmentalist community in New York State. For seven years, we lived, quite contentedly, in circumstances that would strike most Americans as austere in the extreme: our living space measured just seven hundred square feet, and we didn't have a dishwasher, a garbage disposal, a lawn, or a car. We did our grocery shopping on foot, and when we needed to travel longer distances we used public transportation. Because space at home was scarce, we seldom acquired new possessions of significant size. Our electric bills worked out to about a dollar a day."

Highly targeted advertising disproportionately benefits the little guy. I say this as a little guy, running a small dog treat e-commerce company. Almost all of my new customer acquisition is by way of Facebook ads.

If you get rid of Facebook ads and go back to the non-targeted, TV commercial and newspaper type ads, my company might not survive. Purina, though? They'd be fine. They can afford to spend enormous amounts, and they've got a range of products that means their potential customer base is much bigger than mine.

Your local vet can affordably reach pet owners in their area with targeted advertising. If it goes away, that will hurt them and greatly benefit VCA (huge, nationwide chain of vet hospitals).

You're right in the sense that my business model would become inviable, but the result is that you're going to concentrate power even more heavily among the largest corporations. Is that really a good thing?

> if in October 2019 someone said a virus outbreak that could be largely prevented would be lead cause of over 100k deaths over climate change, you would be laughed at.

Firstly, why would someone laugh? Pandemics with a 100k death toll are a fairly regular occurrence, even in modern society. OTOH if you said 1M + most of the world under some form of home quarantine, lockdown or travel restrictions for well over a year, that would have been laughed at.

Second, it's hard to attribute deaths to climate change directly. Natural disasters kill people every year. Who can say with absolute certainty that the death toll in this or that incident would have been lower if not for climate change?

Third, on a longer timescale climate change absolutely has the potential to kill more people than Covid.

I don’t invest in Intel, but I am bullish on their prospects in general. I love that they are an American company that has large production facilities in the US.

I personally have had very good experiences with most Intel products. So that positive experience may color my views a little bit.
