And here we have one of the most reasonable answers in this thread. It's not about the utility of identifying risks, it's the plausibility of someone as knowledgeable as Musk putting his money and name on the line without having already considered a lot of the things some random group of strangers on an online forum would've thought up in a couple hours.

On the contrary, it seems more likely that Musk would've not only thought about risks already for more than a couple hours, but that he would've consulted a lot of domain experts about such things before even deciding to take on such a project. Even the most optimistic business person isn't naive enough to take on something they see as a sure bet to fail. Not to suggest that there haven't been entrepreneurs attempting silly businesses before, but rather that one should pause and think about the possibilities of how something might work, before jumping to the conclusion that they already understand everything there is to know about a project, and that it definitely won't work.

As another comment mentioned elsewhere in this thread, a good entrepreneur's main skill is being able to figure out some unique/unorthodox way to make something work, and capitalizing on that. Now, that doesn't mean that everyone opposing these ideas are wrong or don't know what they're talking about, it just goes to show that a lot of people's default state is one of risk-aversion.

I agree with everything you said. What needs to be feared is complacency. If you ever feel that things are going too easily - that's when to be afraid.

I will be the first to admit I let many _months_ of complacency pass me by before I identified the signs. All the above advice - forcing yourself into the haze of discomfort, breaks this away and forces you to learn new skills. Learning is often glamorized, but in reality, the actual _learning_ phase is painful and uncomfortably hard. I still don't enjoy it, even though afterword, I appreciate the knowledge and extra skills. Instead, it's important to build habits that lead to continuous learning, rather than one-off improvements. Paradoxically, it's easier to become normalized to regular discomfort than rare, unusual discomfort. It has never stopped being uncomfortable to learn for me, but I also have built it my psyche.
When a city in America is destroyed by a nuclear explosion, Americans will re-learn why suburbia was so popular. Hopefully this won't happen for a long time and we will have a good stretch of city living. I love cities, but having millions of people concentrated enough to be killed by a single device; this is very different world than the one humans evolved in.
History repeats itself, in an amplified manner. At least in the era of galileo the general population's prevailing world view was being challenged by new science and evidence. This is backwards, the science has been proven decades ago, countries' policies are being amended to counter the effects. Except in America, and the Middle East. Unlikely bedfellows in science denial.
You know about the word "evidence"?

People hunt moose/deer so their populations are easily controlled with more permits.

When I was little and the wolves were still gone, I remember my uncle being limited to 1 or 2 a season in Wyoming. People don't say no to essentially free meat.

IIRC wolves were only brought back because people weren't allowed to hunt in Yellowstone Park. Wolves spreading to the rest of Wyoming, Idaho, Utah and Montana is collateral damage.
I'm seeing something right now. It's really, really difficult to figure out what kind of crazy valuations people will put on companies. It's reinforced my desire to own indexes all the more. I'll let buy a little of everything and let the money managers battle it out.
The problem is that there are diminishing throughput returns to velocity. You need massive amounts of duplicated track for that to be feasible...on and off ramps for every entrance and exit. On and off ramp lengths grow exponentially relative to target velocity. That might be fine for long distance travel, where on and off ramps can be concentrated in few locations...urban travel not so much.

Well if you figure a mile of urban freeway in an urban area is an easy 5 million per mile which makes it about a thousand bucks a foot. That doesn't include annexation or planning, just construction.

A tbm can make a tunnel for 19k a foot in the right environment (https://www.wsj.com/articles/the-high-tech-low-cost-world-of...), but that cost is dropping as more and more tbm projects since 2000 have driven the costs down.

So basically it's 20x as expensive to bury a highway as it is to build one on the surface.

Ok.

But, when you look deeper, in urban areas there just aren't rights of way available to put new highways, and so you have huge slow costs that grind out projects. In addition, if you can find a place to put one, they are... ready... usually public infrastructure.

This is a private highway... private highways are a good idea. Take a look at https://mises.org/library/privatization-roads-and-highways

This is a bet on free market roads. That is a big bet, but goodness it's not a naive one.

I feel like Elon has some kind of cache of historic photos and documents from the late 60s and early 70s that he is just pulling pages out of.

Anyways, 20x more expensive is very doable and these roads could operate profitably in urban areas (and that's the opening, current cost). Oh, and the son of a gun bought a used tbm, which will save gobs of the cost. Oh, and it's for a ton of jobs (the cost of acquiring the Tbm is a large part of the cost of tunnels), and there is going to be a glut of tbm inventory in coming years.

Add it all up, and it sure isn't a "dumb idea" in some kind of intrinsic, obvious fashion.

Seems like a good bet actually.

It is very old and branched off from the rest earlier than all the other recognized ones. Some say it is not even Indo-European.

But that is a distinction without a difference, all sides seem to agree that Indo-European, including, Hittite, and Indo-European without it are both good "clades". So there is no disagreement about past linguistic events; the only disagreement is the judgement call about what to name things.
If you contacted Rackspace's chat support while logged in, the representative sometimes asked the security question. To which (remember, you're logged in) you could click "Account Settings", "Security Question" copy paste.

A former employer of mine had internal security questions. Five of them. They were all inane questions, the "favorite movie?" type, so I came up with a somewhat random answer and used the same answer to all of them. The one time I had to use it, the representative asked all five questions, and I gave him the same ridiculous answer each time. He did it all with a straight face somehow, and looking back, I don't know why I didn't stop him at the fourth question to ask "if I knew the first three, you really think I don't know the last two?"

Yes, I got in a debate with a denier not so long ago and was quickly able to find papers and summaries of the predictions on growth of ice in the south and decline in the north.

What I find more alarming are folks like yourself that have so little respect for science that they think there is potentially some cover up of the truth.
Ask HN: Any open source drag and drop app(web/mobile) builder?
Any user interface experience can be divided into 3 parts:
a) Visual Appeal
b) Responsiveness
c) Layout

>25 years of web has a solution to the first two aspects. Different companies have solved the first aspect and have even come up with their own visual languages like Google Material Design, Microsoft Design Language, etc. Similarly the open source front end frameworks have been able to resolve the second aspect. However, the third aspect is very subjective and depends on the application. Though most of them can be standardised. As a back-end developer, I'm yet to find a solution to address the three with a single solution. Most of the users don't care about the front end as long as the system works. Proof: Spreadsheets. Users don't need any fancy alternative for an application like invoice or a project management tool. There are already lots of solution in the market which look more or less the same.

Would like to ask the community whether you are aware of any such solution in this direction other than spreadsheets.
Read other people's projects. Read books on design, architecture, patterns.

Deeply analyse those reads without ever touching a computer. If I feel the need to write code I usually write it in a paper sheet and analyse it.
I work on progressively larger and larger apps. This teaches me more and more about coding in the large, in a very practical sense. Every time I learn about something new, my learning is explicitly motivated by the problems that I ran into while implementing the large app.

I started by making a reasonably conplex TODO app, which took a few months. This taught me about the importance of declarative (popularized by React) style programming, and MVC separation.

Then I moved on to building a Vim extension for visual studio code. This took about 6 months, and taught me a bunch about programming larger apps and keeping them bug free. I also learned a lot about open source maintenance. I learned why Redux-style architectures are important.

Then I moved on to working on a fully featured pixel editor. This has been my toughest app of all. I've been working on it for about 4 months full time at this point, and I've learned so much about canvas perf, js perf, the importance of end to end testing, ... I could go on for a very long time. :)

And this is all a warmup for an even larger app I haven't started on...

This approach seems to have worked well for me, and I'd recommend a similar style approach of working your way up from smaller programs to larger apps. You learn lessons from smaller apps that will save you a lot of time when coding larger apps.

Well, that's true but the only reason spaceX was given the money is because the government wanted to put satalties in orbit. They just figured SpaceX was the cheapest way to get them up their.

They had to prove that they could do it before they saw a dime. The NASA has a project and gets funded without having at least a prove of concept (e.g. A single rocket that can do the job) as long as congress likes it. I'm not saying that this is bad, but this way he earned the money.

Furthermore, unlike the Apollo missions, sending satellites into orbit served a practical purpose. Sure the apollo missions were really cool and have helped science a lot but their practicality was a lot less.
1) Find the equivalent of Schaum's in any domain, a book of problems with worked answers.

2) Grind through a bunch of representative problems without studying. Just give it your best shot, you might be able to figure it out.

3) Check your answers and use this as a form of placement test to identify deficiencies.

4) Specifically, if you're getting the complex questions right, you understand the domain. If not, go back to the source material and read it. You'll have a new focus in reading it as you know exactly what you got wrong and you know what points to fix.

Doing it this way is (IMO) the most efficient way of spending your learning time. First do problems with worked answers to find out what you don't know, then fill the gap with focused effort.
Have you ever ridden on a really good train system?

I get the train to work each day and 99% of the time I get to sit down with space to comfortably work on my laptop and I get through a bunch of stuff each way. When I think of the alternative - spending 20% less time but dealing with the risk and frustration of driving and getting nothing done in return - driving myself seems positively toxic.
Don't write a single bit until you fully understand the system you'll build. I usually draw diagrams and or other procedures in plain paper sheets.
Comparing a very common business practice today to an abusive relationship? Really? Merely to call it "taking advantage of" is highly questionable - often it's just part of the deal - you get a free service, that's how you pay. No one is taken advantage of, it's mutally advantageous.
I see this advice often. However I feel like it never seems to work for me. One of the big reasons why is that I feel I don't get a sense of all the incorrect approaches and why they don't work.

In a case where there are N incorrect approaches and 1 correct approach, by reading the code of the 1 correct approach I will get no sense of why the author dismissed the other N approaches. I feel this (understanding trade offs and judging which approach is best) is a crucial aspect of programming that is easy to miss when reviewing the solution that worked.
you are likely referencing a report that concluded the costs for stopping climate change were higher than the costs of dealing with the consequences. The report that I read on that topic came to its conclusions by valuing people's lives in dollar figures and putting those lives at less value for anyone in developing countries.

So, yeh, if you think poor climate refuges have no value then you are right we should take no action.

The problem is that those holding onto power have politicized climate change so that those not paying close enough attention wrongly conclude that we don't need to take action.

I have been a developer (primarily Java) for 9yrs now. But I recently started learning PHP and now I am learning Python. I wanted to learn these languages not because I had to but because I wanted to. And the best way to learn, per me is to pickup a book or a website tutorial, go through all of it in one go and then come back and do some mini projects for yourself which will enforce you to apply the concepts that you learnt. It won't be easy in the beginning but I find this a better way to learn any new programming language or any new concept. Because this way you are actually putting your theory into practice and when you are doing so you also have the big picture in mind.

Everybody is trying to invent shit and make things better. It's true from your waiter at your restaurant who will try to find a way to be more amiable to you, or it's true from the public researchers who just invented the artificial utero when they're being paid nips and wont become billionaires out of their invention. This is not Atlas Shrugged. This is the real world.
You truly need to have heroic levels of dedication to sustain eating 5% less, keeping your home 5% warmer/cooler, and driving 5% less over the long term.

Then at the end of the day it still won't matter because your government chooses to continue burning coal.

It's even worse because if enough green minded folk can reduce enough energy use to make a difference then it drives down the cost of energy which makes it cheaper for others to use more.

This really is a problem that requires everyone to play a role.

Steve Jobs was an idiot. That other guy is nothing special. Show me research mathematicians, hedgefund managers, landlords, or doctors.
I'm upvoting it because it's incredibly common in high schools and college. People have to do tons of repetitive, boring stuff. They have piles of work. Many turn to Adderall to stay focused enough to get it done.

Like it or not, it's how a huge chunk of people in college "keep improving" despite the challenges they face not getting better over time.

Do I need direct experience to know about something?

Here's a question. The latest versions of Javascript supposedly aren't so bad, but some legacy features of the language give problems. There's already "strict mode", which at least requires that variables be declared. Consider a "strict 2" mode, with more restrictions, intended for new, cleaner code. What features should "strict 2" disable?
That is awesomely terrifying.

No. Up to 80% the cost of renewables is, what you pay to set up the solar cells or wind generators. And these costs are known and quite competitive (if not cheaper already) to building a new coal plant, and definitely cheaper than building a nuclear plant. If there is enough controllable power generation in the other 20%, by todays technology that would be gas power plants mostly, this is about how far smart grids can deal with the varying nature of the renewables. Only going beyond 80% there are significant additional costs for storage. But as battery costs are significantly falling, it makes only sense to discuss the costs, when we really need them and then know the true numbers, as this is quite a few years in the future.

The Seattle viaduct is a good example of transportation infrastructure that is very vulnerable to quakes. They're replacing it with a tunnel, so I assume they have worked out how much damage an earthquake will do. At least the tunnel can't fall on anyone, unlike the viaduct which would pancake and render the waterfront inaccessible.
Rust for Clojurists
I think you aren't quite understanding the point. It's not that some language wouldn't have dominated (in the interest of interoperability and functionality needs), but that it probably would have been a product by MS or some other homebrew language. Javascript being codified with the hackneyed ecmascript standard, was the death nell for efficiency in web apps for the last few decades. Without the standard, we probably would have seen a shift to other technologies (some of which would have failed like Silverlight) on emerging browsers, in hindsight.
