Electric cars have the potential to be a key part of the solution to load management on a fully renewable grid.

The vast majority of people will usually charge overnight and don't need to regularly charge at peak times. Through intelligent charger management, you can distribute the load of charging across the entire off-peak period. The UX for this can be fairly straightforward - by default you charge at the cheapest rate, or you can press a button to get the quickest possible charge.

The real dividend comes from bidirectional charging, using the collective resources of plugged-in cars as a load balancing reservoir. In exchange for a discount on your electricity, the grid can take a small percentage of your EV's battery capacity when needed. A typical mid-range electric car has a 40kWh battery, which represents about four days of electricity consumption for a typical European household.

Nissan and the British utility regulator ran a two-year trial to examine the long-term impact of EVs on local grid infrastructure. The trial used intelligently-managed unidirectional charging. They concluded that about 32% of local electricity circuits will need to be upgraded by the time that EVs represent a majority of vehicles on the road. This figure could potentially be lowered further by bidirectional charging technology.

America still has huge potential for efficiency savings, because of the immensely high average household electricity consumption. The average American household uses nearly three times as much electricity as the average European household. Air conditioning is only a small part of this disparity, representing about 18% of the electricity consumption of American households according to the Energy Information Administration.
A movie may not be an accurate representation of reality. But, point taken.
Wait, do you think that the Tulsa race riot happened because people didn't have radio or TV? Wtf?

Race riots occurred in this country because of the acute structural contradiction between the white settler-nation and the other nations; these contradictions have not been resolved by radio and TV in the interim. We will see more of these riots in the future.
If it had been a deterrent, people wouldn't have done it, and we wouldn't have slow loading pages in the first place, and Google wouldn't have an AMP initiative. However, We have slow loading pages, and Google has AMP, which means that load speeds hasn't deterred stopped anyone from adding a ton of JS bloat
> This should be simple. Artists gets a contract with the property owner to use the wall for a duration. If there's no contract, the owner's rights prevail.

That's not at all how art works, and thankfully we have plenty of case law and common law tradition to the contrary.
"Its development is backed by people at Mozilla, Microsoft, Google and Apple."

It seems this is for real then?

JS has had a surprisingly long life actually given its original use cases, and I understand the objections to wasm, but I guess that something like this was inevitable given how big the browser is as a platform and how web apps have been steadily fattening on the back of a suboptimal language, which, if this goes ahead, can be confined to just UI again.

They are planning to add support for gc, threads, bigger mem, tail recursion, etc [1], so will it be running everything efficiently? Even on mobile, given its backers?

Yep! Let's get rid a forest on this idea alone.
Almost all crypto operate by requiring only one actor authorise create a valid transaction. You loose your one-single-point-of-failure-private-key and its over, what's needed is a more sophisticated system at the protocol level which requires secondary authorisation.

It is highly difficult to synchronize an orchestra without a conductor, that is, some centralization is needed (like CPU clock). Same problem with bands but they tend to use some kind of rhythm generator. It seems that birds have learned how to sing together asynchronously.
The rise of Slack and friends is a definite detriment to actually hunkering down and getting work done.
The catalyst of such a shift could be a very good thing, e.g. exceptional internet speeds everywhere
Oh, rubbish.

Bitcoin is fundamentally incompatible with sanity and a rule of law ( which is what is needed for regulation ). If I were to start a bitcoin exchange ( and myself and those that I know have way more technical abilities to actually pull it off ) and apply sane KYC and risk mitigation strategies, the crypto-nutcases would be screaming like banshees that the exchange is not acting in a "spirit" of bitcoin which is:

1) Allow anyone to launder money/coins

2) Ask no questions

3) Make all transactions irreversible (i.e. do not follow 'in the name of' ledger )

4) Demand no validated tax information (i.e. leverage power of the government to make players play by the rules )
Now I expect that there will come usability experts from google/facebook/amazon and tell you that an average user does not event know what latency is.

I was wondering what federal law could support the artists here. Answer: "Visual Artists Rights Act of 1990 A subsection of copyright law"

These arguments don't really hold up given that Tesla has already deployed a charging network really wide.

FWIW all of the chargers I've seen didn't require new transformers or lines. Heck they put in 20 spots in Centralia without even digging up the road.

You arent driving very far then. 250km is barely an afternoon on the road. Im doing some training next month in comox, 260km away from work. Im expected to drive there and back in the same day.
The EU legal limit is

> a break or breaks totalling at least 45 minutes after no more than 4 hours 30 minutes driving

and

> 9 hours in a day - this can be extended to 10 hours twice a week

https://www.gov.uk/drivers-hours/eu-rules

The range of a 100KWh model S on the page for the UK ranges from 319 miles at 70mph (four and a half hours) to 514 miles at 45mph (eleven and a half hours). At 100KWh and 3+ miles per KWh (https://forums.tesla.com/forum/forums/real-world-range-new-o...) that's still 330 miles, plus.

Certainly seems like a reasonable claim that the battery can last longer than you can safely drive, particularly if you're not gunning it down a nice fast road.
Thanks - do get in touch with how to get on.
Crystal seems like a great high-level language and alternative to Ruby, but the biggest blocker for me using it more generally is the lack of multi-threading support. There is WIP support for threading but it has not been committed. Moreover the Crystal developers either don't do a great job of updating their multi-threading roadmap [0] or work on multi-threading has died off. (I assume it is the latter because the thread-support branch has not gotten any commits in 10 months [1].) Ultimately if I wanted the high-level aspects of Ruby or Python and wanted more performance and great thread support I'd probably go with Elixir (even taking into consideration BEAM weirdness).

I don't consider any of that to be bad faith.

The alternative view is that the owner allowed graffiti artists many years of free usage of the space and they're trying to penalize him for it by preventing him from rescinding that offer. The tax status of the building isn't relevant. Every graffiti artist that tagged that building knew it could come down at any time. They knew they could be either replaced or entirely removed. To claim some ownership to the exterior now that he wants to tear it down is ludicrous.

If anything, I see this type of litigation to have a chilling effect on landlords allowing public usage of their property. I wouldn't want to open myself up to future litigation just because I allowed some artists to paint a mural.
Thanks! I'm still in the process of really grokking linear algebra as I only just took a class on it, so this is helpful.
I'm interested in OmniGraffle and will check it out.
I don't see how ride sharing services are ever going to be more efficient than public transit. Or how it will even be barely possible to replace the one with the other in a place like NYC.

Riding sharing is about utilizing a vehicle in a temporally more efficient way, but it does little to improve spacial efficiency during peak times.

The commuter rails, subway, and buses are far more dense than a fleet of self driving cars with one to two people in each can possible be. Even with the increased density that might plausible come from better driving and so more tightly spacing, it would simply be impossible to get everyone into and out of their offices across Manhattan during the communing windows without the density of mass transit vehicles and the utilization of underground space.
The latter does not preclude the former. :)

That said, the wastefullness of it doesn't appeal to me, though some of the ideas behind it do. I would think an adaptation of a e-ink display would be much more practical and much less wasteful, while conveying similar meaning.
On the other side of the spectrum, there's been reports of some countries having a negative energy price at some points, thanks to all the windmills and such generating so much energy there's a surplus. Pump those into charging cars (during the day or night), and they can also act as components in the smart grid, switching charge on and off depending on peaks in the power grid / power generation.

I wonder if fusion power will become viable within the next 50 years, and whether it gives us fuck-you amounts of power at low cost. Probably not, nuclear power is far from free too.

As a country, we can land a rocket back on the launch pad, but we can't run a train faster than 80mph. Sad.
The problem is that measurable success is going to change the experiment.

If you consider that there is no constant landscape, it's always changing and always an unknown, the best option is to try a plethora of different ideas, hoping some will succeed.

It's more like fighting a war in an unknown battlefield. If you play it just one way, you are more likely to lose than if you try many different strategies at once.

The ones that succeed will be self-sustaining, for as long as they are successful, anyway, and gain you enough ground to compensate for the strategies that didn't work.

If this wasn't true, nature would only have produced one single organism rather than a billion or more.

Not to take away from what is being done in this project, but I had to read the HN comments to figure out that this was a set of software for printers.

One of the things I really miss with electronic book/music collection is the cover art: many of them are scary, unique, atmospheric, beautiful, and very much a living part of the album itself.

E-ink devices are brilliant things, but had I encountered Dragonlance without Elmore's paintings - or only in black & white - they may not have made the impression they did.

So a collection with large, good quality cover art, combined with qr codes that enables/plays/downloads the relevant book/album to your device is a pretty neat idea.

> Although I've read in several places that once global warming is engaged, you cannot reverse it because of stuff like melting methane ice spots in the tundra.

I'm fairly confident that point of no return has already been passed. Permafrost has stared to melt a while ago, causing bacteria to take hold of things they couldn't for x amount of years, catching up on releasing co2 and such that would otherwise have been in the atmosphere a long time ago already.
If I was building an exchange for crypto here's what I would do.

1. Encrypt you users private keys client side with a password only they know. Now I just hold encrypted keys my side.

2. When the user wishes to make an exchange I would create the transaction client side let them sign it and do the exchange.

This way funds are now encrypted by default at rest and if compromise occurs the thief gets encrypted private keys only. Hopefully the users chose passwords secure enough to avoid compromise.

It's not perfect, but can we finally move away from the hot wallet model.

p.s. If you want to build this, and require advice and backing let me know.
Ride sharing does help with parking though. Which is almost as bad a problem.

> However, the artists would paint over previous works, so it's not like they were permanent installations, they lasted from days to on occasion a year.

That's not true. Some of the works were permanent installations, including tribute and memorial works from artists who have died. Only some spaces were designated for temporary installation.

> There was impermanence about the art. So, i think it's mostly about not wanting to lose their "canvass" than to preserve the art.

There's no need to put "canvas" in scare quotes. There's plenty of case law that helps define what an installation is, in the context of art. This isn't a novel concept.

> Given that the canvass was a building owned by someone else, I don't see much of a case.

The owner agreed to let them use the space (and even charged them for it, along with double-dipping into tax write-offs for the building). Legally, that gives them a pretty strong claim to the space.

The problem with progress bars as the coder is that it's often difficult to tell how far you are into a process if it's not a repetitive sequence of similar steps.

Transferring a file byte-by-byte is easier that a list of arbitrarily sized files. Fixing that would require reading all the file sizes first, or some complex logic to determine when to pre-plan the updates.

What about some kind of "learning progress bar"? It keeps track of the updates that have been made and predicts how long a new user will take based on previous users experience with the bar.

The classic case is installation progress bars, repeated uses of same/similar sequences of steps with indeterminate length of time. But if you aggregated the real-time data from all those progress bars, each new bar becomes a kind of dynamically-updated prediction of how much time is left on the bar.

Norway already has very generous social welfare programs, and nobody who is willing to look for help is dying in the streets. The notion of undeserving youth abusing the welfare system is also far from hypothetical.

Consider: I hold university degrees in two STEM fields and earn a decent salary in the private sector. My wife is currently finishing up her education and is receiving a very basic student loan/scholarship. We have two young children to support.

However, my friend and his girlfriend, who were out of work this year, were receiving more in government welfare put together than I was getting paid after tax, and they don't even have children. It frustrates me that the government is taking my hard earned and much needed money and giving it to my lazy friend, who uses it to gamble and buy useless luxury goods. And I know several other examples of people in my age group who complain to their doctor about being "depressed", so they can start living on welfare. In my eyes, these people are undeserving, and a symptom of a broken system.
Very interesting to see how this turns out for artists.

From one side, there are studies that show that brief interruptions boost the brain searching for creative solutions.

From another side, nothing gets done because FB, Reddit, cats and the likes tend to pull one in longer than expected. If somebody interupts you they go away after the issue, social media is there with another item forever.

Maybe we are seeing something fundamentally new, coming slowly with this idea?
Six-digit passwords are fairly secure when combined with strict limits on the number of attempts allowed, how much money can be withdrawn in one day, and heuristic fraud detection.
There is a third option beyond go bankrupt or pivot, as this story shows very clearly - cease trading with the EU or citizens of its member states entirely. Like the effect of FATCA but in reverse.

That's the decision this small training firm has taken. It's a loss of 5% of revenue, they say. That's not bankruptcy or pivoting.

This seems to be the unsurprising outcome of the EU's modern "obey us or we crush you" mentality. The UK is walking away. This small company is walking away. Apparently Microsoft is at least thinking about it for some products (the connect site is back now but looks semi abandoned). How many others will look at this and conclude the risks are too high to justify the costs?

GDPR does not seem like a well thought out law. I have always been satisfied with my ability to delete things from the cloud. If I end up being banned from useful services because the costs of complying with the EU's very transparent attempts to bulk up their budget by repeatedly fining tech firms, I will not be happy.
Thanks for the response. Proliferation is not something I had considered, and to me, certainly is a legitimate concern.

Kinda.

The net itself do not have much in common with telegraphy, but many of the early computers that ran it were operated by a device that came out of the improvements to telegraphy.

Yes, the teletype terminal, or TTY.
The landing page is as well-written and informative as 80% of the product announcement posted here, and I agree with you.

I sense a you didn’t read the post / don’t know what Luddites were.

Put less flippantly: The Luddites hated technology because they feared it would take their jobs. While this project calls a lot of strong technological conventions into question, it doesn’t reject technology nearly as fundamentally as the Luddites did. It also has nothing to do with the feared obsolescence of labor.

There are certainly good use cases for them but one of the best ones is as a second vehicle. That's more or less the situation I have in an exurban locale. An SUV for weekend trips, snow, hauling stuff and (in my case) a small good gas mileage car for most local trips.

What I wouldn't do is give up the ICE SUV. There's no way I'm going to deal with the hassle of a rental or the uncertainty of a charger system whenever I have a longer drive unless the economics became really compelling.

No, seriously, I miss all those things... I'd kill (no, not really, but close) for a CDC 6600 console, a Tektronix calligraphic display terminal or an IBM 2250.
Somewhat off-topic, but as someone interested in k8s, why is it seemingly such a pain to set up in non-"cloud" environments? I know that Rancher exists - and I'm waiting for 2.0 to drop before migrating to Rancher-managed k8s - but beyond that the whole "ecosystem" of k8s seems pretty unfriendly to get started in without using AWS/GCE/Azure/etc (to the point of not being able to set up a cluster on bare metal at all!). Am I missing something here?

> cars are more emotional than rational :-)

Depends; in my country there were / are significant cost / tax benefits for getting hybrid and fully electric cars (for lease cars, and there's quite a lot of those here). If driving an electric car is cheaper then people will go for that too. Does Tesla still do free usage of the supercharger network for the Model S? That's another incentive, given the cost of electricity over time.
Apple reduces speed as batteries wear out, report suggests
Over the next 50 years if solar roofs take off ( https://www.tesla.com/solarroof ) I don't see it being that much of a problem on the country side. We probably won't need to rebuild the entire grid, may be able to leave some part of the grid behind. May even be cheaper to do so with savings compared to the alternative options
Would you have preferred a confident but unsupported statement? Maybe presenting a nuanced view undermines trust in science, but I think I prefer that to blind trust without understanding.

If charging happens at the place where the car spends most of its time, then even domestic 16A/230V sockets would be enough for typical usage (for atypical usage, there are superchargers).
Still, its a traditionally impermanent art form - so the injury to the artists is not the same as, for instance, destroying a statue or slashing a painting.
