Can anyone chime in how this aircraft is so energy efficient? It seems like the props on the wing will give a ridiculous amount of drag. Also, one of the key requirements for an energy efficient rear prop plane is super laminar air going to through the rear prop for efficient thrust. The wing design seems to remove this advantage.

Edit: Also, I thought smaller props for vertical flight is significantly less efficient than one large prop like a helicopter?

That being said, I always had a soft spot for aircraft startup after working at one in my younger days. Pretty interesting to see how this ends up especially with Sebastian Thrun on the team.
Do you know of a tool like Keel, but for Docker Swarm?
I think that one result is a bit misleading.

79.6% said they consider the ethical implications of what they are asked to do.

82.3% said they would report ethical concerns in some form.

58.5% said they would refuse to write code they thought was not ethical (36.6% said they are unsure).
These stories leave out the other half. Over all that time the value of the property has appreciated significantly...to the point where $800,000 condos are a starting point for affordable housing. Figure 320 units at $800,000 with a 20% net per unit and it's $51,000,000. Many of the units will be significantly more and there's retail. The potential returns for developing today are likely well north of $100,000,000.

It's pretty simple, if regulations are really stifling development, the value of developable land will decrease. It isn't in the Bay Area. Like the rest of California it continues to trend upward.

> Maybe being first to market is overrated?

Sometimes being first to market yields an unshakable dominance in that market for a long time to come... Mostly not though :)

What you're pointing out is often called 'second movers advantage'. Apples iPhone is a pretty decent example: by not being the first phone provider Apple got to enter a maturing market with a mature offering, use their own core competencies, and dominate. That's hard to do if you're bogged down with backwards compatibility and fighting to make the tech possible.
Depends on the goals one wants to achieve.

In consultancy for example, what is relevant are soft skills, business domain knowledge, the technical ability to jump into whatever technology is the current hot fad and start contributing as soon as possible.
I don't like that they're touting no emissions. Electricity has to be generated and in the US that's mainly coal. Hybrid vehicles are closer to having it right where running the car charges it and you can get by burning significantly less fuel. Strictly electrical has not been shown to be an energy saver or a flag bearer of emissions reduction. In many cases so far it has been a cause of more pollution than modern engines using oil.

I have tried to teach couple of close friends programming in Java before. Most people are interested with what you are building and excited to learn. But after writing some code with not much visual result, they interest started to fade in. So I would recommend to start html/css/js so she can see results of her work and get more interested to build more. ))
I just went on incognito mode and googled the title of the article. From google search results, I followed the WSJ link that showed up.
Ah but this is merely an experiment. It most likely will land as a Test Pilot addon, and later upgraded into a setting, just like Container Tabs were.
Swapping batteries is a no brainier for this tech. There is zero reason to have a 500k aircraft waiting around charging vs having 2+ set's of batteries.

Electric cars have a long enough range and are mostly single family so swapping is less useful.

Reserve is a much larger issue, aircraft want to keep ~1hour of reserve these things are starting with less than that.

I was thinking something similar, and per the Bend Oregon article that was here before (https://news.ycombinator.com/item?id=16517929) it could make commuting work from further away, although with only 100 mile range that is a bit challenging. (Bend to SF is 500 miles)

I am also wondering about the ergonomics for people who are mobility challenged.

On the plus side, their launch material successfully has gotten me past thinking that they are building quad copters for people into thinking about what they might be used for. The numbers pencil out for relatively short commutes.

Late to the party, but the proof requires integers with infinite amount of bits. With real-life programming languages there's limited number of bits in integers, and this means that the proof doesn't work with any real-life language such as Javascript.

Consider just 2-bit integers (because it makes this easy, in real life the number of bits is of course larger). If i in F(i) has just 2 bits (possible values thus are 0,1,2,3), each Fn(i) can be represented by a table of four 0/1 values. The function just returns the value at the table in the input index. This also means that there are only 16 possible functions Fn() for a 2-bit input (as return values 0 and 1 can be combined in 16 ways in the 4-entry table). There may be infinite amount of lexically different functions, but based on what the functions actually do, most of them are duplicates that provide the same functionality.

All possible functions with 2-bit input value, and their respective 1-bit return values can be written out to a table:
input: 0 1 2 3
result:
f0: 0 0 0 0
f1: 1 0 0 0
f2: 0 1 0 0
f3: 1 1 0 0
f4: 0 0 1 0
f5: 1 0 1 0
f6: 0 1 1 0
f7: 1 1 1 0
f8: 0 0 0 1
f9: 1 0 0 1
f10: 0 1 0 1
f11: 1 1 0 1
f12: 0 0 1 1
f13: 1 0 1 1
f14: 0 1 1 1
f15: 1 1 1 1

The point is that even if a function is defined by a completely different algorithm (and thus lexically different), it can be reduced to a table lookup, where the size of the table is defined by the number of bits in the input. For instance from the functions above, isOdd() is the same as f10() and isPrime() is the same as f12().

Now, if we take any function above, we can find another function in the table that provides correct answers for 1 - Fn(i). For instance for f12() we have results 0 0 1 1, so we need a function that provides results 1 1 0 0. This is f3(). This is clearly a function that is already in the set.

If there are more bits than 2 available for i, the amount of different functions just grows, but is still limited in the same way as with a 2-bit input. So in order for the proof to work, input variables need to have infinite number of bits.

You are correct that these no longer apply to the most recent Node versions. Crankshaft is still being used in Node <8.3.0.

Crankshaft got totally disabled starting from V8 5.9. Node 8.2.1 uses V8 5.8.283.41, Node 8.3.0 uses V8 6.0.286.52.

I'm pretty sure there is still a big number of projects running on Node <= 8.3.0.

There aren't any differences important enough to worry about at the "I am learning Python" level. Down the road, problems between one and the other will get resolved by Googling into StackOverflow, blogs, and the Python documentation. Googling to resolve problems is part of learning Python...and every other programming language these days. Hence Googling for answers is part of learning to program.

Good luck.

I'm not going to criticize that particular aircraft, no. I respect the effort it took to get it up in the air. But everyone is building an electric, pilotless vehicle for ride sharing, which also happens to be an oversized RC multicopter. Like trying to put Tesla, Uber and DJI products and business models into the blender and get guaranteed receipt for success. I'd love to see more thinking outside of context here.
That graph isn't showing years of experience vs. salary, it is showing average years of experience by role vs. salary. Most developers with more than 10 years experience are at the higher end (at least) of that graph, but those numbers just aren't what the graph represents.

I'm actually going to conflict with some other suggestions here, but when I first started learning to code, I started with simple HTML, CSS, and JQuery/Vanilla JavaScript. I took a framework: bootstrap and started building websites. I liked this approach because the elements are well documented and easy to pick apart AND even more important, you can start to see the results of your code immediately.
Good point. I was also puzzled by that result, given the responses to the question I mentioned. The picture it paints is that software professionals feel their duty is to consider, complain, and (less so) refuse, but ultimately responsibility lies elsewhere.
Google released a tool to help with continuous deployments called skaffold [1]. Haven't used it myself (just using bitbucket pipelines) but looks like it's a relevant tool to this. Nice.

How does a cold start perform, I'm guessing with sandboxing of v8 vs a whole new container, and deserialization of a single script into a free sandbox v8 slot (perhaps they store the AST or preJITed code for even faster start? - not familar with v8 internals) it is much faster than cold starting nodejs on AWS lambda?

The other points in your post are equally dubious, do you have sources?
I've worked 12+ hours 6-7 days a week at multiple points in my career for an extended period (the longest lasting 8 months). In my most recent case (which was 10 years ago), I was starting a company with a friend and we signed client contracts very early. We knew what we were obligated to build. I learned Javascript, CSS, and PHP (coming from a background of embedded C/C++, Python scripting, and Linux/Unix administration) at the same time as I shipped a vertical-specific CMS. I didn't have a family, significant other, or other time commitments and so I could focus 100% of my energy on the joys of learning and building.

I don't know that building a large CMS tuned to a specific vertical is trivial, but it wasn't the most technically challenging problem I have ever worked on. There were a boatload of details (especially in the analytics and traffic arbitrage modules), very tight deadlines, and entirely new technologies to learn. I was getting normal amounts of sleep per night (5-7 depending on how I felt) and when I was tired, I'd take a half day or day off. I communicated mainly via SIP phone, IRC, and email with my cofounder and both of us understood when the other needed some time to decompress. The thing was, working for ourselves building something we wanted to exist, we didn't need much time for decompression.

I made enough off that business to be debt-free (from a starting point of about -140K USD), build up savings and retirement accounts I ignored before, and coast for the next 18 months doing whatever I felt like (which was a self-directed study of computer science and a lot of Magic: the Gathering). I didn't get rich, but I did improve my situation substantially. If I didn't have commitments to my family, I would jump at a chance to do something like this again.

>Everything else should be able to be said and be heard

But what does that actually mean? If all you're saying is that the state should not stop them, then relatively few people disagree with that, but the argument usually goes further. There are many ways people's speech can be limited without the involvement of the state. Be that de-platforming, protests or economic or social limitations.

>Restricting Free Speech puts power among the ones in control of Speech.

This is true, but the reality is there will always be restrictions on speech. It is not physically possible to let everyone speak to everyone, or even just those willing to listen. However we structure our societal discourse, it will always privilege some speech over other speech.

We have to engage with, and be ready to criticise, the implicit decisions being made about what speech is privileged and why. Because if we don't, then we cede power to those who already restrict speech with these decisions.

Just saying "don't restrict speech", and thinking that gives everyone a voice, is incredibly politically naive.

I suggest picking a project, and focusing on it while learning how to code. Learning is such a continuous process while coding that I think you need some kind of focus to ever feel like you have learned enough to apply the skills. Plus, that project could be a portfolio piece when she is seeking work.

Also, the project doesn't have to be a business - I think utilities that you would use, whether it's family communications or something funny, are perfect.
Well, it's use async if you need the ~40% decrease in ram usage for your concurrent I/O access.
Coal is 30.1% of US electricity generation and dropping fast which is a long way from 1/2. We do use 31.7% natural gas, but that's still only adds up to 61.8%. On top of that the thermal efficiency is vastly better than cars.
Ok thanks.

Do workers play nicely with managed CNAMEs?
Honestly its not worth it. I know that is a privileged position, but the quality of life was so bad that I just ended up with a ton of savings that I used to take 6 months off and travel and decompress/deal with all the mental health stuff resulting from the job after I quit.
My understanding of the Everettian interpretation is that all worlds that are possible in QM exist and we exist in one of them, the wiki article for this is called many-worlds. I may be being obtuse but this seems like a fundamentally different claim than what I normally see as claimed when talking about the multiverse. The multiverse, in my understanding, claims that there are infinitely many universes, even some that will have different QM from our universe because those universes started differently.

To use a CS analogy, many-worlds says that the tree branches the maximum number of time at each nodes. Multiverse claims there are infinitely many trees. Do I have a different understanding then you when it comes to what constitutes a multiverse?

> Say we take a firm stance on only wanting to keep around models that are constrained by scientific experiment.

My initial asking of this question is that it appears to me that the multiverse is not constrained by scientific experiment. I have read most of the comments and your gets the closest to something predictive but even then, it is still just one interpretation of QM. The other option is that there is something in string theory that implies multiverses but as of yet string theory is just theory and from what I understand string theory doesn't require a multiverse, it requires more dimensions which might cause a multiverse.

I ramble as well.

Do you think adding type annotations or using typed js (typescript/flow), the optimisations could be improved? Since the types are providing more metadata about the code?
It's deeper than that. People here like Tesla because it's forcing other car makers to build decent electric cars. That's something that needs to happen if we're going to move away from fossil fuel dependence.

SpaceX is cool because there's a really good chance they'll be more successful at missions to the moon and Mars than NASA has been recently. They're both forward-thinking companies.
I think lowering the time cost of coming into the office would lead to more telecommuting than less. Since you can get into the office in 15 minutes, you don't have to go to the office every day just in case you need to have an impromptu meeting.

I don't get how it is physically possible that this plane is energy efficient? The smaller prop, the less efficient the thrust conversion. You also need laminar air for rear props to be efficient. The drag on the wings should create a ridiculous wake behind the aircraft. I would love to learn how KittyHawk are trying to mitigate these problems (which are huge constraints even for major players).

> If Comcast announced they were doing this

But they wouldn't do this.

They would do something like detect the popups and then inject ads for additional Comcast services into them. And they would do it secretively rather than making a public announcement beforehand. And they would hassle customers to no end about switching services in protest of that behavior, whereas most browsers would just provide a checkbox for turning it off.

Comcast is in no way a victim here.

Same thing. Your site has only one worker script, and each request is therefore processed by at most one Worker. You can of course merge many independent pieces of logic into one script -- it's code, after all.

Enterprise customers are allowed to have multiple scripts mapped to different URL routes. This is mainly so that different teams owning different parts of the site don't step on each other. However, generally if you stuff your logic into one script rather than multiple, it will perform better, since that one script is more likely to be "hot" when needed.
