Let's talk about Solar City.

Their product is intended to be a solar roof, indistinguishable from a typical roof from street level. Costs look to be in the $50,000+ range. The marketing is that homeowners will not only drive electric vehicles, but go completely off grid by storing the energy collected into Tesla batteries.

In order for this to make financial sense, there needs to be an ROI for the homeowner. So... how long will it take the homeowner to recoup that, say, $75,000 investment?

I am currently spending about $125/month on electricity. That's $1,500 per year. Two Tesla's would run through about $1,000 [0] of electricity in the same year. That's $2,500 per year I'd spend on electricity to my grid operator.

That's 30 years to break even.

I could probably buy an equivalent roof-mounted system for half that, and the batteries, and see a return in 15 years. Is the aesthetic worth the longer term payoff?

Or would Tesla see more uptake in new home construction where the cost of the roof can be amortized into the construction cost?

I understand that Solar City has a different financing biz model, are they going to continue with that.

Coco doesn't use any underlying network - it forms the bottom-most layer of a permissioned blockchain network. When a ledger (could be any ledger, Ethereum as in the demo or otherwise) is integrated on top of it, the ledger decides whether to expose metadata or not, and to whom.

Maybe I misunderstand your question?
Exactly; Gutenberg/pgdp won't accept stuff published after ~1930 because it is too hard to clear copyright. In the case of an anthology mag you have overlapping copyrights of the mag and the authors of the stories.

Very much this, yes.

And, in such circumstances, your best bet is to drive west. Barring that, either north or south. East will generally be downwind.

Of course, there are areas in which westward road travel is somewhat limited.

Yeah, I kinda think they and the investors are hoping that electricity demand increases and the tech becomes much cheaper while their RnD is funded by millionaires who care about the aesthetics and the environment.

Sure, if everything in the world had competitors that were trivial to switch to. If I suffer through bad customer service for two hours that's bad but it's not itself enough to make me switch companies. As long as I get my money back I'll still be willing to work with most companies.
I thought so far that silver is chosen because of a hair changing color with age.
With more age usually comes more experience, and with that higher wages. That's the canned answer.

But in this case I see your point. Many of these young CEOs just don't want older people in their offices. They have youth as part of "their culture". They also generally assume that older workers will be slower to adapt and less welcoming of a more volatile work environment; both frequent traits of many tech companies.
You mean boys right? Teaching girls how to code is waste of time they are genetically predisposed for secretary kind of work. You don't believe me? Read the google manifesto.
The SEC has taken a clear position that whether or not it's a "smart contract" or the like makes no material difference into whether or not you are offering a security. Making a cryptocurrency was suggested as a way to finance Tesla's business operations, so it is almost certainly a security in the eyes of the SEC. At this point, your choices are either to sell unregistered securities or to follow SEC rules anyways, at which point, why not just go through conventional channels?

"Fund your business by issuing cryptocurrencies" is an idea that will likely end in defending yourself legally against the SEC. Bad idea. I don't recommend it.
That's also why third-party analysis of how government organizations spend their money is so crucial. Without such analysis, there is no check on wasteful spending.

They work for the people, after all.

Do you believe that the author has some privileged position w/r/t defining the meaning of a story for everyone else? I see no reason to believe that. As far as I'm concerned, no story has any universal, objective meaning. Meaning comes from the interaction of the story's contents and the reader's mind / beliefs / knowledge / biases, etc.

The author can always say what he/she intended the story to mean, but that really has no bearing on what any individual reader takes from the story.

When I was a kid we cooked hot dogs with a Westinghouse Dog-o-matic:

https://www.google.com/search?q=westinghouse+dog-o-matic&tbm...

The two metal bars down the sides with the prongs sticking out were connected directly to the AC plug (with a switch that turned them off with the lid open, of course). You pushed the hot dog ends onto the prongs and closed the lid. Your household AC went directly through the hot dogs, and 60 seconds later they were done!

Space v. time is one dimension, but energy costs and infrastructure requirements are other critical elements.

A passenger car and a long-haul airliner are about equivalently efficient, on a fuel-per-passenger-mile basis (assuming a high load factor for the aircraft, and a single occupant for the auto).

Rail is far more efficient, and time-competitive with air for modest to fair long trips (given high-speed rail).

Shipping is the most efficient form of transport by far, but also one of the slowest.

Automobiles require roads of some description, though they can flexibly shift routes across these. Aircraft and ships require ports, though have freedom of movement exclusive of these (with some choke-points: straights and canals, mostly, for ships).

Rail is almost the equivalent of "ships on land", though the right-of-way itself is required. The requirements for these are comparatively modest for basic service, though high-speed and high-capacity routes, and switching, increase requirements.

It's an interesting field.
Yes. However, do I know enough to be of any assistance? Maybe. Am I an authoritative source in regards to rail transport? No.

But, if you have a question - I may know. I have done quite a bit of reading, but no academic research and no publications with regards to rail transport.
Show HN: Apihopper – API Monitoring and Testing
A bit of a tangent, but a comforting thought is that unusually strong turbulence counterintuitively has a beneficial effect on fatigue crack propagation. Aluminium always has cracks and they're keep growing but a heavy load that opens up a crack plastically deforms the material around the crack tip so that its natural state is for the crack to stay open. But the rest of the structure forces it closed. Once it's in this state, subsequent smaller higher frequency loads don't apply the usual damaging tensile stress to the crack tip so it doesn't grow like it otherwise would have.

Not just amoritized though - less the cost of alt new roof, maintenance, and replacement. I believe Tesla is offering a lifetime warranty
Homeowners often pay extra for aesthetics that appeal to them.

But lets pretend they don't. How quickly does a normal roof recoup its costs? For at least the beginnings of a fair comparison, you should look at recouping the surplus over the normal cost of a roof.

Also, how are you spending $25k on batteries?

This sort of comment seems to attempt to try to take the most negative reasonable possible look on the situation, then throw in a bunch of exaggeration and unreasonable suppositions.

If your point is that normal roof-mounted solar is going to be cheaper, then yes, they pay for themselves in much less than 15 in many locales. But your solar panels plus new traditional roof are not going to pay for themselves in 15 years unless it's an amazing market for solar.

Three Questions About Each Bug You Find (1989)
I didn't get that from the interview. It implied the bot learned the game itself from a blank slate.
There's also the EOMA68 project:

https://www.crowdsupply.com/eoma68/micro-desktop

And somebody else who appears to be building a shader compiler for the Mali 400 GPU here:

https://github.com/yuq/mesa-lima

If both these projects succeed that would be a fully free arm laptop with a fully free GPU driver. Apparently it will also be possible to print out the laptop itself using a 3d printer apparently being designed and built by that same EOMA68 guy to deliver the boxes people already ordered.

Also it looks like the touchpad is just a little square of lcd touchscreen. If that part of the design is kept theoretically you could play quake inside the touchpad.
You can cut maybe 5-8 years off that if you factor in the cost of non-solar roofing. I doubt too many people are signing up to replace their roof if it doesn't already need replacing.
To be fair to floor labels starting with 1, I have never seen a floor with a negative number.
I feel that while the author shouldn't be the arbitrator of what the whole work is about, they should have a say in what it's not about. e.g. if Lewis Carol would have stated that Alice in Wonderland is not about drugs; then the public should respect that and stop telling everyone else that it is. Following that thought to its logical conclusion, if extremists of any kind praise a work for promoting their view while the author denies that it does; with whom should we side?

I do think there's an interesting discussion to be had about it.
From my extremely limited understanding of legal matters, I'd say this should be a criminal fraud case. Maybe the police can get through the "wall" at Amazon.

From the article:

Would forking really help or is it because it's hosted on github? I mean US citizens would still contribute. Together with a lot of people from other countries. But moving it to a European server with a European domain should increase their safety from those takedown requests, but also limits their impact when you're not on github anymore.

The issues is that there is normally a expectation of paying for things like produce. Unless there was explicitly a "Free Produce" sign, I would expect to have to pay.

There is no expectation that you need to pay for the data sent to you later; if payment is required for access, you're told so and need to provide it to continue to the resource (or otherwise provide proof that you had paid, e.g. logging in).

There hasn't historically been and can't be an expectation of payment later because that would be untrue for many, if not the vast majority, of websites. Additionally, there has never been an expectation that the client will render everything you send to them. All browsers have the option to disable JS and images, and always have.

It's these differences in expectation and culture that I believe provide the difference between your examples and the web. Violating these constraints would cause legal issues in the vast majority of systems, would mean running old software would be illegal (Chrome preloads links under certain circumstances, but doesn't render them), and would also end up forcing users to run code they didn't choose to run (there is no expectation or knowledge of what code the server will send and choosing to not run harmful code would be illegal), which would be an interesting thought experiment as a civil rights violation. It would also force me to, say, accept a EULA for Flash, even if I disagree with it because I visited a site that randomly sent me a flash payload. Or what about something without a linux runtime; I would have no ability to avoid committing a crime, because I don't have the choice to accept the rest of the content that came with the content I can't run, but am legally required to run.

Violating the very assumptions of how the web works would have terrible ramifications.

The article mentions that they're using Nexplanon, which, though it's a hormonal method as you say, is absolutely not comparable to chemical castration. It's recommended for use by Planned Parenthood among other organisations, as it's convenient and has a low failure rate.

All the "chemical castration" and "severe adverse reaction" seems to do here is introduce unwarranted FUD. As far as I'm able to find, the number of complications due to the implant are insignificant. It's like those disclaimers in drugs commercials where they mention a headache relief medicine might give you a heart attack. Sure it's possible, no it's not something many people need to worry about.
More predictable does not imply more consistent. It just means you can nail down numbers like 10th and 90th percentile more easily. They'll still be far apart in many areas.

NK from a non-western perspective [Quora]
It can take 30 years to break even. It's attached to a house, which will be around at least that long.

When you sell that house in the future, it's STILL worth $2500 a year off the electricity bill. The house buyer will be willing to pay more for the house for that; if they keep the house for five years, they will have spent $12500 less on electricity, and they'll still have an electric roof to sell to the next buyer. So you should be able to recoup a chunk of that investment when you sell, because a house that can fuel cars using sunlight is worth more than one that can't.

They can't restrict your speech in general,but at work they can and should do whatever they want. Practically, there is a difference. Unless they are willing to fire you, they can't stop you - get the difference ? For example, if you are so valuable that they are not willing to fire you, then they can't stop you. And if you are not, perhaps you should concentrate on work at work
> Also, how has BandCamp done so well as an independent music service? Any lessons to learn there and to apply to SC?

If you mean financially, it's because they take a 15% cut of an artist's sales, up to $5k, after which it drops to a 10% cut and they also take out CC processing fees.

IMO, if SoundCloud were smart they'd find a way to team up with BandCamp right away. Unfortunately, I don't know what BandCamp would get out of it.
You'd think so but I've met people who havr, in total seriousness, stated that a dollar of their money was worth more than 10,000 human lives and they shouldn't have to pay any taxes to help out other citizens. Some people truly believe that if you have more money, you are a better person

If he doesn't want me to block the ads then he should not serve the pages to me in the first place.

My home's roof has another 20 years on it. So I'll be tossing half of it's lifetime if I replaced it now. That's partly why I mentioned new home construction would likely be an easier market. Moreover, it's a 3000 sq ft ranch, with larger than the average roof area. The Tesla roof is likely going to start at $50,000, (I said "$50,000+") so I'm thinking $65,000 for my house. Batteries are probably in the range of $10,000 for enough to hold charge for the cars and run the house.
