> With as conservative as aviation is, and as long as airplanes last, I doubt anything about it will be quick.

You may well be right.

> I’m amazed it has taken this long to get a single approved 100LL replacement, considering high octane unleaded fuels have existed for decades.

Outside of some specialized racing fuels, no. And nothing fulfilling the other requirements (distillation curve, vapour pressure, etc etc) of 100 octane aviation gasoline (this is measured with the MON procedure, as opposed to RON or AKI you'll find at your local gas station) at somewhat reasonable cost has previously been introduced.

I think the reasons why it has taken so long are 1) it's a genuinely hard problem 2) it's not a very large market.
It’s not that much of a problem either in the US outside of Silicon Valley and venture backed companies. Plenty of older guys in the not so cool industries.
I feel like we're missing the point here. The dangerous groups are those execs you mention who will have the decision about whether to move something into production or not.

When this technology gets into their hands with a dev leash it will be recklessly implemented and people will die.

Not sure about propaganda, but sounds like a lame-ass piece, taking for granted what BS official sources said.

As if they'd reveal an informant or other (more plausible) means of getting that information.

They had arrived at a suspect house, identified the driver, but had to rely on the clothesline for such information? I call BS. But it makes for a good story.

Why is shipping rarely profitable ? the barriers to entry are large, and at least in theory that should give companies some stable margin ?
I've observed this and it's just appalling.

It doesn't matter that 50 year olds can do the same work just as well, no, management seems to want freaking Energizer bunnies on their team.

Nevermind that they don't actually get more work done (and more importantly, better), it's just about being "passionate" about doing the same shit every day. Wtf.

Ah, the context-unaware personal snipe. These flagrant and pouty birds spend their days sqawking at other random birds in an effort to achieve some kind of short lived feeling of superiority. They often go after other birds with no regard to the situation at hand, which causes their actions to look exceedingly stupid to the casual birdwatcher. This behavior is where they get their name, as their actions are "context-unaware", and makes them very easy to spot.
Because nothing's free.

Sure, having the one black or gay character in a tv show is obvious tokenism, particularly when portrayed as shallow stereotype, but it seems to me as if any attempt at representation nowadays is written off as "political" or tokenism, even when it's sincere.

It's like, you can have Asians OR Latinos OR Blacks OR gays but no more than two, and they can't stack, and you definitely can't rewrite an existing character to represent some other race, religion, gender, sex or nationality even if you yourself are of that race, religion, gender, sex or nationality. That's a narrow minded view and unfortunately a common one.
Just keep in mind that there are regular engineers like any of us working at Blue Origin and giving their best to achieve something, make a living and tackle really hard problems.

Some viewpoints expressed on HN feel like social media fed hatred, people often forget that there is a massive army of brilliant people doing stuff that most engineers would dream of. There are Facebook/Google engineers working on advertisement tech and we generally don't scorn at them. Adtech is far more "uncool" than space exploration.

I say kudos to Blue Origin to lift a building sized socket up to space with humans in it.
A lot of Americans I know seem to associate vacation with super luxury trips. They don’t seem to understand the concept of just taking off and relax but instead want to do trips that go to five star hotels and spend 100 dollars on dinners. No wonder they can’t afford vacation. When I compare myself to colleagues I can often do a one week trip for what they are spending per day.

Academia's purpose is to produce research, typically measured in publications per unit time. Optimizing one paper leads to a global reduction in the size of the literature by pruning opportunities for subsequent research, harming the overall performance of the system.

One should ask (rhetorically) why these outlets seem to have an incel-like obsession with esoteric Big Tech stories when there are an abundance of more pressing and pertinent matters they could cover.
Put another way, I think after a certain amount of money, the owners (or executives, really) of these sorts of companies are more interested in power projection and influence than they are in immense profitability for the companies they run.

Wiser to retreat (but retreat unpalatable for USians). Make corps pay directly. If govt pays it's just socialized cost, with no impetus to move.
"They're less open to new ideas, and more extroverted and driven by self-interests." This is something like Karl Marx describing capitalism and entrepreneurs. It's wrong.

I'm against mandatory vaccination and I am open to new ideas, I'm introvert and I'm not driven by self-interests in fact I'm driven by interests of all stakeholders.

So the article's statement is completely wrong.

Edit: Endless lockdowns are more devastating for poor and lower class people. Middle class and rich people will always find their way around.

Funny enough while ago when I watched a documentary about Italian Mafia researchers said that even criminals understand that so called FUD (Fear, uncertainty, and doubt) is only hurting their business because society can't function like that and they decided to end endless wars, conflicts and violence in order to minimize civil unrest and make people feel happy and safe again.
Last time I did this and calculated how much I've spent it hurt.
The Simplest Math Problem No One Can Solve
Overall inflation doesn't account for it. A dollar today is worth ~40 cents back then.

Wage inflation for professionals living in San Francisco, however, does. A lot more people in SF are making ~$400,000/year, than were making ~$10,000/year, back then. Hence, the restaurant can charge ~4x, and still be fill its tables every night.

I don’t think it compiles on windows (netdb.h doesn’t exist there, I think), so you’re fine there, too, from a security viewpoint.

However, if somebody did a quick and dirty “make it compile” port (include winsock2.h instead and, possibly, replace some functions/argument types), I think that would create security vulnerabilities because the fopen on Windows might support using backslashes as path separators.

Even if it doesn’t, there’s UNC paths (https://en.wikipedia.org/wiki/Path_(computing)#Universal_Nam...) to worry about.

That made me wonder whether other OSes might have similar features. Reading https://pubs.opengroup.org/onlinepubs/007904975/basedefs/xbd..., I’m not sure that forbids Unix from doing something similar. It says

“A pathname that begins with two successive slashes may be interpreted in an implementation-defined manner, although more than two leading slashes shall be treated as a single slash.”

That opens the door for doing special things for paths that start with //, for example by supporting “//machine:foo/bar/baz” on clusters.
Microsoft messed up a lot but they are doing a lot of cool things for quite a few years now. It it hard to believe they converted but it makes a lot of business sense: keeps devs happy, make software for major platforms, keep pushing into businesses. The giving away creates enough goodwill to forget the crap of before and not get the blowback on the (good or bad) closed source software. It is like Gates Foundation: you know it's tax write-offs or whatever negative spin someone wants to give to it: it is money to good causes that otherwise is not there. And very large amounts of it, in both cases IMHO.

- prediction. Write down what you already know of the topic. sentence of a mind map. Dump it all out. Look at that and w rite some predictions or questions that interest you about gaps.

- deepis dive. Watch through videos, go down the wikihole, read many abstracts. Whatever, just lightly wash lots of information over yourself.

- read the thing: choose a limited number of key points per section you will remember as you go. Write a progressive summary, or map it out.
Write quiz questions for yourself as you go.

- then: apply it. Compare what you learned with your predictions. Review your quiz questions and summary periodically.

That was a method I tried a few times.. it was a lot of overhead, but had its merits in terms of trying to work with the brain.

There's multiple factors in play here. Inflation is one.

Population growth is another. The Bay-area population went up by ~2 million people between 1990 and 2020. Even if the income distribution remains the same, the number of potential diners who can afford an expensive meal goes up.

Income distribution is another. If the percentage of the population who could afford an expensive meal and would buy one goes up, the number of potential diners goes up even faster.

Perceived social impact of an expensive meal is another factor. If more people believe there is social benefit in buying to an expensive meal, the number of potential diners goes up. This could be due to a larger pool of expensive meal buyers trying to impress each other, better awareness of expensive restaurants by the general population, etc.

Edit: changed "going to an expensive meal" to "buying [...]"
On the contrary, Canadians are clearly more sane than what the US is doing. The lockdowns here notwithstanding.

> The second year you earn 100K, and if you don't save me money you have now made 20% commission and only saved me 800K (1m - 100K - 100k).

I disagree. Savings is a competitive advantage usually dropping your costs, time to market, and increasing profits, or efficiency, even if you don't reflect that on the books. Managers could ask employees to do more things as opposed to reducing the labor costs (layoffs), e.g.

Also since it's software, those savings typically compound. E.g: so I save tedium in accounting for $1M in the first year. It's so successful that you expand my efforts to other parts of your company. The next year you still have $1M + whatever I have added. Or $2M+ over the course of 2 years.

If you decide to go with a external package and pay a recurring licensing cost -- which is pretty common in the software industry, then you'd be paying maybe 10% of whatever you save per year. One software package we were looking at was $6M/annum. That's roughly 30 engineers being paid $200k for a year to come up with an alternative. We're using 5 engineers to do the same thing for less.

While it's hard to gauge true costs, paying my team $1M to save you $6M in recurring costs seems like a bargain, and something that's hard to argue against. In fact $2M might not be a bad number either depending upon how management sees it.

Significant digits isn't always the best way to denote a number and its accuracy. If a simulation says 552 +/- 100, then how would you write down the fact that the expectation is centered around 552 and there is an error of 100, using a single number?
No, you fail at elementary economics in a typical bitcoin-fan fashion. Your personal wealth is your share of overall wealth in the economy. Your share will increase or decrease whenever you become wealthier or poorer relative to others. This is what happens when there are changes in the relative prices of assets, wealth is redistributed. And, again, scarcity isn't a predictor of price. Scarce means in short supply. It doesn't imply, by any stretch of the imagination, high price. No school of economic thought claims such nonsense.
At least, for vaccinated people, they have better outcomes the first time they come into contact with the virus. After that contact, they'll also have naturally-derived immunity. So the vaccine is a way for people to acquire their natural immunity more safely.
I never refuted that, and in another comment I equally lambasted this practice.

So, what are you contributing to the conversation?
Just for a second (before I read carefully) I thought Disney and Science Applications International Corporation collaborated on a VR project 25 years ago.

Well, from my perspective, a bunch of us are playing some very weirdly human constructed game of wasting life years on work and passive content consumption.

If we ever make it to a cashless utopia, I'm pretty sure someone's going to look at us and see how much untapped human potential was wasted on years of watching a screen and experiencing dopamine release.
> If we're advocating for using paper bags over plastic bags, that means we're advocating for way more CO2 in the atmosphere.

Not exactly. The point is not to use paper bag, but to use durable/persistent bag from any material (even plastic) as long as you can.

For example, I almost never use one-time plastic bags, because I have backpack, so when I go to a grocery store, all the things placed into the backpack.

In such case (from energy perspective) it's easier to peoduce 1 backpack (32l) for several years of daily use instead of paper/plastic/etc ONE-TIME bag.

Unfortunately, that approach doesn't work with other things. For example, it's impossible to buy yogurt not in one-time plastic package and we didn't find a "mass market" solution to that problem. Same goes for any other ONE-TIME package
Bitcoin mostly reuses wasted energy where there is no other better paying customer. Even if we would stop all Bitcoin mining on the planet, it wouldn't make any difference for this wasted energy, it wouldn't be put to other uses.

Blue Origin arguably did the first verticals landing from “space” as defined by 100km of altitude in 2015. Though the lunar lander is perhaps the more famous vertical landing from space in 1969, following earlier soft landings like Luna 9 1966, and a lot of earlier VTVL rocket research at the time.

SpaceX started on powered decent in 2011 achieving it’s first landing from an actual orbital space flight in 2015. I don’t mean to dump on Blue Origin but their achievements are really just around the definition of space as 100km which is completely arbitrary, their effectively just publicity stunts.

It’s possible that Blue Origin will create a useful system for space exploration, but based on past progress their years if not decades from that point.

The push to use clean energy for Bitcoin will ultimately lead to the increase of clean energy and lower costs of it for all, especially, for out of the beaten path locations. It might seem like a waste of energy but all technologies look like wasted effort until they are not.

This is a great example of the transition happening. Coal --> gas --> Solar? Nuclear? Hydrogen? ...

I think we are about to pass the tipping point of Bitcoin being around until money is no longer needed. There will be a time when Bitcoin will be expensive enough that it will be profitable to build a Solar Power plant to mine Crypto in the middle of the desert with nothing else around. I bet it will be in a bit over 2 generations, 40+ years.

This statement is from someone who used to think that $10.00 was a crazy amount to pay for Bitcoin.

Movie theaters can't go out of business soon enough for me.

I hate being trapped with rude people talking and using their phones during the movie. Not to mention people who don't believe in baby sitters, and bring their infant or toddler along for a good scream fest in the middle of the show. And don't get me started on loud eaters, flatulent people, etc.

I think they've been on borrowed time since the 80s, when video stores got big. First run movies are their only hook now, and they're loosing even that with movies like Black Widow premiering on streaming. I hope more films premiere on streaming.
1. The number of households that own a gun has actually declined, according to surveys (US law prohibits collection of gun ownership data). We may have added guns, but the number of people + gun availability seem to be declining. If we look at just historic numbers like you say, I would argue that reduced availability of firearms _does_ seem to reduce crime.

2. Despite this decline, the US has a higher rate of gun ownership and availability than other high-income countries, and this correlates with one of the highest rates of homicide amongst those countries. So my naive read of the data would be that an even lower availability of firearms would lead to an even lower homicide rate.
