I think what you may be onto there, is that some of those people were not really your friends, in the sense you thought they were.

The ones that don't come over anymore are the ones that think about it and decide they don't want to see you bad enough to take the time. Doesn't mean they hate or despise you. They may still consider themselves your friend, but they're not, at least in the way you had thought.

Ten loyal friends is a big number :-)
This comes up often in these discussions but, barring any indigenous lands, there's nothing especially inhospitable about central aus. Las Vegas is in the middle of a damn desert, and Arizona/New Mexico are both extreme climates compared to much of the US but they are still livable and many people actually prefer it. I can't see why this would be any different in Australia...
They can also just project the image onto your retina directly, but this requires some serious tracking I don't understand or know if it really exists.
A thousand (1e3) metric tons (1e3 kg) of anything, up a thousand meters (1e3), has 1e9x(10)=1e10 Joules of potential energy on earth (g=~10 m/s2).

At 80% conversion (8e9 J) and assuming 1/8 of the energy is "payload" after paying for the train to go up, that's still ~1e9 or a GigaJoule.

At a -20% grade, you're looking at a 5km train ride, which reasonably might take a half hour or less (1800s). So, you're generating GJ/1800s = 555 KW by pulling down the mountain, assuming the rocks magically teleport into and out of your hoppers. (Thanks @calvinlh )

That's approximately 100-200 households per train pair, which might generate 10 K$ / month in electrical sales?

I've switched from digital marketing manager type roles with direct reports to an IC dev role at a much smaller organization at that. The pace is _much_ slower with lower expectations, and people don't seem as receptive to your feedback as an IC (even when giving background of prior experiences, people still seem to anchor your skills to only your current title) so I've learned to stay in the very narrow dev lane and play the stooge role while taking the necessary steps to keep my skills relevant.

It is obviously hugely dependent on the organization's culture, but I've encountered more politics as an IC dev than any management role. The shift to IC is much more how can you make a low-mid manager seem like what obviously should be done is their brilliant, novel idea in addition to actually implementing the tasks at hand-- so overall productivity of the group is exponentially lower.
Based on my experience working on different teams and interfacing with the SA teams (but not actually working as an SA, mind you), being an SA at AWS seems to be one of the better positions in terms of workload, limited on-call responsibilities, etc, but you do need to be very comfortable with constant customer-facing responsibilities (which can sometimes be better than on-call, and sometimes can be worse than on-call) and the team is still dragged down by the general Amazon/AWS culture.

I wrote this months ago, but worth repeating- from a Microsoft perspective, as Java was seen as the Microsoft platform killer by many:

“Java was a token threat. Bill knew it would not be performant enough on clients for Applets to succeed. They had to rebuild their language to put every fixed-size object on the stack because sorting an array<int> on a typical machine took forever.
That’s why Java still doesn’t have operator overloading. That Java battle would be on the server, and [MSFT] didn’t have a good language to bring to the battle there. Wired and co loved to paint a picture of Microsoft v Java as Goliath v David. Not true - Java was a speedbump.

The real threat was dumb terminals (aka web browsers). Even today, the world could run on Mac OS / iOS and Safari. If Microsoft was okay with sacrificing Windows market share and instead controlled content and services, they would be much more valuable.”
Indeed, the idea of LVT/Georgism is to charge, if not 100%, then close to that amount of the rent commanded by the (unimproved) land. The very idea of the whole thing is that, in order to claim a piece of land for your own usufruct, you need to compensate the public for taking that piece of the commons for yourself and walling it off and preventing the rest of the community from using it, i.e., you owe the community a market rent for that piece of land.

We can fiddle around the edges, e.g. the tax being 50% of market rent rather than 100%. But the principle remains the same.

Note also that houses used as main dwellings would be exempt or pay a heavily reduced rate.

EDIT: So taking that example, let's say your house rents for 1000$ (I've no idea if this is reasonable or not). Land according to your appraisal is 60% of the property value, so land rent, that is, what you owe as LVT, is 600$/mo or 7200$/yr.
What to do?!

I can’t talk about this in person or in the streets.

Sucks.
I'm skeptical. If the minority gifted* students could change the culture of the regular classroom the bullied nerd wouldn't be such a trope.

Git is hard to use mostly due to "clean commit history" cargo culting. The commands that cause the most trouble are the command that re-write history, and there really is never a good reason to use them beyond "I want my commit history to look like a line".
I wanted this to happen so much. I really thought type="javascript" meant that other languages would become available, and that Perl's dominance server-side and embed-ability meant that it would definitely become a client-side option.
Rentals should always be more expensive than buying then, no? You're gaining a service overtop of the place to live. Not to mention, you should be able to leave atyhe drop of a hat, rather than be required to have a 1 year lease

Absolutely true. I've converted more people to GNU/Linux over the last two years than in the twenty years before that. The vast majority of people in my (third world) country do not have SSDs, so GNU/Linux is their only hope of having an usable and moderately secure machine.
Southern California has linked the carpool/ZEV lanes for several freeways, so for the best case of "north of los angeles" to "southern orange county" you wouldn't ever "change lanes" - you'd take the left fork of a gentle Y, which overhead lines can already do fine.

Speaking of Southern California, Interstate 57 had some work done around 2000, they were installing some sort of lane sensor substrate into the right two lanes of the freeway. there were some people claiming they wanted to do power delivery or collection too - like solar roadways.

re: epistemic strictness

You don't think HN users are capable of realizing when they are engaged in mind/future reading, even if it was an explicit rule? You surely know the userbase better than me, but this seems unlikely.

If you want nothing to change, so be it, but the idea that functionality changes cannot have an effect is very frustrating.
You can get pretty close to an HDTV with nothing but a dumb VGA monitor.

Context: as late as 2012, I had nothing but two Sun Microsystems (rebranded Sony) 19" Trinitron CRTs. The picture quality on these monitors was _phenominal_, and I kept it as long as I could, before the siren song of more desk space got me to give them up.

To get from component video to VGA, I had a color space converter. Then I hooked up a 3x component switcher to give me a few more inputs - for the game consoles, of course.

To get television, I had an old DirecTV tuner with a VGA output. I didn't actually have DirecTV service, but it had an NTSC/ATSC tuner, to which I had a pair of rabbit ears hooked up.

To get composite and S-video input, I had an RF modulator. The DirecTV tuner tuned to channel 3 would show whatever was on that.

The weak link, of course, was HDMI - an HDMI to analog converter was, at the time, more expensive than real televisions (this article appears to show that this is no longer the case).
I think this is naive. Individuals are probably overwhelmingly good, but a corporation generally gets away with as much as it possibly can. I think this is because you can diffuse personal responsibility to a much greater extent when you are acting on behalf of a corporation. Corporations probably do good things insofar as they provide them cover to act increasingly selfishly. An individual on the other hand runs into their own conscience much more frequently when they're acting on their own behalf.
These will help you regardless of tenure, but it may be helpful to emphasize them in this order as you gain experience:

1. Be a sponge: learn everything you can, especially by doing things. Realize it’s quick and easy to experiment with most tech tools/languages/etc. and that there nothing is out of reach. You can learn and understand literally anything a computer does that seems too technical or magical at first glance

2. Keep an eye out for and surround yourself with smart, successful, kind people

3. Work hard and work towards things that matter; this may mean a big project that’s important to the business or spending an evening doing a favor for someone to make a friend

4. Choose firms and roles that will give you the experience you want (e.g. working for a firm with a modern tech stack that will give you relevant and marketable experience). Realize it’s valuable to stay in a company/role long enough to become an expert, and also valuable to leave and get some new experience

5. Be positive, share the knowledge you have, be humble, but come out of your shell

6. Understand the intangibles that affect how people see you, e.g. dressing and presenting yourself professionally, learning how to communicate your ideas, having professional empathy for colleagues and supporting them however you can

Engine braking is definitely always much louder than regular braking. Don't piss off your neighbors.

The bypass valve on semi's you're referring to is not the exhaust. The huge BRAAAAAAAP that you hear coming from trucks when someone cuts them off aren't an exhaust bypass valve, its them slamming on their brakes to avoid a tragic 20-car pileup.

It is a release of the compressed air-fuel mixture momentarily before combustion called a Jake Brake or Compression Release Engine Brake[0], that Semis and large commercial vehicles are equipped with that provide for additional braking in an emergency.

What they're doing is releasing the compressed air-fuel into their exhaust, just prior to combustion. This causes the engine speed to drop instantly, slowing the truck down. It will surprise you to learn that semi trucks have pretty terrible braking performance, loaded or unloaded. They all use drum brakes.

It is strictly prohibited to bypass a muffler or emissions control device in the US. While cars get away with it all the time, a commercial truck carries additional registration, inspection, and license restrictions which makes this not only dangerous, annoying, needless and harmful, but extremely expensive.

Commercial Driver's face much steeper fines for equipment that is out of specification. Many commercial drivers are required to inspect their vehicles before they depart for even so much as a top indicator light which is burnt out, or they may face harsh penalties and fines that would make your skin crawl. $10,000 citations are levied daily.

This includes financial literacy.

Tbf, I have no idea what the average level of financial literacy is. But I worked in financial services and I can confirm that: having a lot of cash from a job in which you are supposed to have financial literacy (corporate lawyer, accountant, etc.) and/or working in financial services in which you have completed exams on financial literacy...does not mean you have financial literacy/will make reasonable decisions.

It shifts your view of reality significantly when you are in your early 20s, just out of college having to explain basic elements of finance to: a financial adviser managing $100mm of other people's money, a corporate lawyer worth ~$10mm, [insert other horrific situations].

...there is no other way to gain knowledge apart from learning, it is not some innate skill. But that supposes that people designing the course know what they are doing, this is a fairly ambitious assumption given that anyone who has financial competence is, generally, not designing courses for the state govt.

And, ofc, lack of information isn't why people make poor financial choices. One of the flaws of financial regulation (and economics) is assuming that if everyone had perfect information, they would make the same decision. This is equivalent to the guy who has a view on the death penalty and thinks anyone who disagrees with them does so because they don't have the "correct information". The issue isn't information, people know they shouldn't take out the high-interest loan when they have to speak to some sleazy guy in an ill-fitting suit at a strip mall (these heuristics work well). People take out these loans because of poverty and a lack of options (particularly in the US, massive unbanked population, large banks won't deal with poor people, unconscionable level of arbitrary fees that fine poverty). Unless the course teaches people how not to be poor, it is flushing money down the drain.

(A side-note for the target reader: the reason why rich people make bad decisions also isn't bad information...it is usually a combination of greed and studying to get stupid i.e. subjects like economics. Wealthy people only see upside, they will believe utterly ludicrous shit that makes no sense because...hey, they are wealthy, and they got wealthy through those smarts (as an example, every wealthy investor I have ever met has gone through the "goldbug" phase...it is amazing how consistent this is). Again, you can't teach it. Ironically, if you combined the paranoia of a poor person with the risk tolerance of a risk person, you would actually have someone who makes decent decisions...but those two attributes tend not to be found within one individual.)

That is absolutely correct!

Alas, let's look at the bright side, learning all those topics you mentioned in you "Life School" are only one google search away, free (monetarily); they only require an investment of time.

People learn complex things like playing Fornite and Minecraft or understanding Baseball/Football and other sports the same way.

Maybe it's a matter of twisted modern darwinism?
Correct. Not only HN users but humans in general—I just don't think we work that way. The way we work is that we have our preference on X and then we propagate that preference through every edge in our mental graph of associations from X.

One can imagine a user saying something like "Although I personally am against nuclear power, since this is the 'optimism' thread it isn't the best place for my counterarguments so I'll post them in the 'pessimism' thread instead". However, such people are somewhere between vanishingly rare and unicorns. Statistically they may as well not exist.
Huh, what is "tech?"

NCSA Mosaic, meh. That will never catch on.

The combined civilian and military deaths in Germany, France, and Britain in both wars (~6 million in the first war, ~9 million in the second, we can even throw in ~2.5 million people who starved to death thanks to British colonial policy in India) pale in comparison to the casualties suffered by the Soviet Union (24 million dead out of 200 million people), and more depressingly, Poland (5.6 million dead out of 35 million people).

The Soviet Union, of course, inherited Imperial Russia's participation in WWI (~3 million dead), as well as the Russian Civil War that immediately followed (Another ~8 million dead).

If you're ever wondering why Russia is so paranoid about maintaining buffer states, and foreign encirclement, look no further than those numbers.
I thought everyone in the future would spend their free time reading science journals, which I discovered via Usenet (because no one in my physical environment read them). Two decades later we elected a president who has said that climate change is a Chinese hoax and wind turbines cause cancer.
Given that China has unilaterally decided that the joint declaration on Hong Kong no longer has meaning (https://www.reuters.com/article/us-hongkong-anniversary-chin...) why doesn’t the international community just consider the agreement to be fully not in force, and treat Hong Kong as being back under British control once again? Right now China is issuing threats even over Britain offering visas to Hong Kong residents (https://www.theguardian.com/world/2020/jun/03/china-accuses-...), and I don’t see why the entire free world doesn’t just band together to issue sanctions at this point.

As an aside, I’ve seen zero action from the current administration with respect to managing China. Maybe they’re still figuring out their plan but as valuable time passes I feel they’re going to spinelessly let China bully Hong Kong and the world. Do we need to start emailing and calling representatives to see action? Any other ideas from this community?
You can argue as much as you want about what is theoretically is, but this is exactly how all practical attempts ended up, aiming the lower common possible denominator.

Hmm. What about buildable land without utility access? You need water, but you could have a purification system and a septic system. You need electricity, but you could have a solar system and a backup generator. You need heat, but it could be electric or propane.

Seems to me someone could make a fair amount of money by creating the package to make it reasonable (not just possible) to live on "unusable" land. Oh, and this is a site that has a lot of people looking for startup ideas...
Which is irrelevant to the incorrect idea that housing market appreciation is a Ponzi scheme.

The point of a Ponzi scheme is that the underlying asset was only valuable if you could resell it to someone else for more then you bought it. Housing, by definition, doesn't meet that since it's still housing.

Whereas Madoff investment credits or whatever are worth literally nothing now, because they never represented any underlying asset.

Seeing my crypto investments dwindle to zero, I need to learn skills that will pay me money. I thought I would be able to retire off this but nope. So I need to learn skills that will make me employable.
