There is no near/medium term limit to PV manufacturing volume from materials scarcity. The rarest material used in a typical crystalline silicon solar panel is silver, part of the conductive pastes used to make electrical contacts on cells. Limits on silver availability could limit annual production rates with present mainstream designs. But manufacturers have found many ways to economize on silver use so that total PV silver consumption rose only slightly from 2011-2015 even as annual production volume rose 80%.

SunPower uses plated copper for electrical contacts instead of silver pastes. Their modules are also the most efficient on the market. But the high efficiency and avoidance of silver come at the price of higher process complexity during cell manufacturing which leads to higher costs per watt of capacity. SunPower is at least an existence proof that you can produce modules at large scale, at high efficiency, from abundant elements. I expect other manufacturers to substitute away from silver too if increasing demand pushes silver prices up too high.

Sometimes you'll see people claim that solar can't attain really large volumes because of dependencies on "rare elements." Those claims are probably referring to the tellurium in cadmium-telluride PV modules and/or the indium and gallium in copper-indium-gallium-diselenide modules. But you can safely ignore those worries because CdTe and CIGS together account for a very small share of the market; crystalline silicon dominates PV at over 90% share.

Sounds like iif it's anything that comes from one of their "Solutions" then it's NC, ND, free for private use but can't be used for anything to do with location (eg mapping, direction finding, etc.). Pretty far from "open".

However on the legal page [2] they say it's CC-BY-SA for "Mapillary Photos [by which] we mean the publicly available street level photos."

It goes on "Attribution should include a clearly visible link to mapillary.com or to the Mapillary photo page directly. Suggested text: "Photos from Mapillary, CC-BY-SA, by @username. ".

The they say "Other photos, videos, logos, map tiles or graphic material on the site are not included in this license.". Which puts the final nail in the coffin of having any idea if a particular photo is a) provided by a solution and so not CC-BY-SA but proprietary, b) an "other photo" and so not licensed at all.

Not sure how you get to the photos without using their "Solutions" either. Prima facie it's a pretty confusing position; I've read a few copyright licenses [ie lots] in my time too.

I'd have to assume the position they're aiming for is "do what you like and if you make money or leech our userbase then we'll sue the ass of you".

This is good though:

"If you would like to use a Mapillary photo in a Wikipedia entry, go ahead and donate the photo to Wikimedia Commons. If you like, we can do it for you. Just send us an email and describe where you want to use it, and we will donate." (/legal.html, === (version 2, April 29, 2014)) //

So presumably it just needs someone to list all the photos and say "please add these to Wikimedia Commons" and all those images will be, per their agreement, released to CC-BY-SA without their specified form of attribution (as that license simple requires reasonable attribution AFAIR).

[But now we need the full legal terms to be able to tell if a "Mapillary photo" is one they created, one on their service, or something else; you'll notice it's not capitalised and so is not the same Mapillary Photo as elsewhere.]

Licensing is hard, yo.

Do you have any hypothesis on the potential forces at work?
Unless you've purchased phones from all the "more established" brands and verified whether they're sending data, this is hardly sound advice.

"More established" brands have a history of leaving secret backdoors and phoning home just the same as the Chinese devices.

One was discovered in a range of Samsung devices just a couple years ago. Lenovo, same story, spyware and garbage hidden deep within their gadgets.

The only solution is to take a chance, buy a device, test it. If it's backdoored, return it if you can, and call them out on HN/Amazon reviews, etc.
Ask HN: What is your favorite BSD jail manager?
I'm somewhat new to BSD and there seems to be a few popular tools of choice. I was leaning toward using either ezjail or iocage, but I'm curious what admins of more experience like and why?
I guess it's good you've got a solution that works then !

If you had the option the simplest way to poll for changes would be to do a hourly/daily/weekly zone-transfer. But many DNS-hosts disable those for security reasons.
With hard drive size increasing so quickly but hard drive transfer speeds basically flat, I wonder if there are long-term implications for them with respect to recovery from backup and downtime. For example, if a whole rack goes down, and they are on 32TB drives in the future, for example, could it takes a week or more for their data to get online?
"Proud" might be a stretch, but some very small tools I get a lot of use-value-for-coding-time out of and thus feel warm fuzzies about:

https://github.com/brennen/bpb-kit/blob/master/home/bin/gif-... - wrap Byzanz and Festival to record a gif of a screen region (and tell me what it's doing so I know when to do stuff).

https://github.com/brennen/bpb-kit/blob/master/home/.sh_comm... - an alias for navigating directory history.
"I can’t recommend technical writing as a day job for fiction writers, because it’s going to be hard to write all day and then come home and write fiction. Nowadays I work as a freelance writer, so I usually do contract technical writing part of the year and then I take time off and do fiction writing the rest of the year. It’s too difficult for me to do technical writing at the same time as fiction writing — they draw on the same parts of my brain. " - Ted Chiang

Can this be a blocking factor for coding side projects as well? What if companies offered a role where 11 months of the year, you do the company's work, and one whole month you get to make whatever you want? Or a project-based role that covers a year's expenses.

> Responses essentially amount to go RTFM.

Let's be honest, reading the docs should be everyone's first step before posting a question. So many questions follow the template of "I want to know how to do this but I don't want to put in any effort." The volume of those kinds of questions are what drove me away - not the moderation.
> I noticed almost all of the mainstream US media became an echo chamber for pro-Clinton content.

I like media in general and thinking how it is used to control and manipulate people. Especially the idea of the illusion of freedom. I've always recommended Manufacturing Consent by Herman and Chomsky.

That analyzes how corporatist media is used to manipulate and control public opinion, and I think at not time has it been truer than in the last election cycle. CNN's Cuomo "these documents are illegal to look at, let us interpret them for you" is such a wonderful example of it. I love it. (sorry everyone, I've mentioned that multiple times).

There is a new twist here and that is social media. I wonder what they'd have to say about that.
Good question. For sabotage, right now they are not easy targets because most plants are behind one of the strongest structures known to man (reinforced concrete containment domes) and employ ~130 paramilitary guards.

For wars it's another story, most militaries could bomb the hell out of a nuke and cause some grief. One rather crazy idea to deal with this is to build nukes on large ships, 10 miles offshore. Worst case, they retreat as designed into one of the most unaccessible places on the planet (the bottom of the ocean), where they stay cooled and avoid releasing radiation until things calm down and the planned recovery operation begins.

Other pluses in this scenario include possible shipyard construction (could be cheap), ability to use power purchasing agreements to get nuclear power to countries that don't have nuclear regulatory infrastructure (the NRC could regulate plants worldwide), and enhanced safety since you're always coupled to a great heat sink and there are 0 people living within your evacuation zone. Anyway that's a bit far-fetched but I love the idea.

The last time I talked with some people in the nuclear industry (that was before fukushima) I was kind of excited for GenIV reactors. They destroyed that enthusiasm by telling me that they're still decades off.

The Bolt sacrifices aerodynamic efficiency for cargo space according to

http://www.digitaltrends.com/cars/chevy-bolt-family-design-a...

"the Bolt still ended up with a drag coefficient of 0.32. The Toyota Prius has a coefficient of 0.24.

The Bolt’s relatively high drag coefficient explains why, even though its battery pack is more powerful than the Tesla Model 3’s, it has a 200-mile driving range, compared to the the Tesla’s 215-mile range, according to Electrek. The Tesla has a coefficient of 0.21"

More than enough reason for me to wait for the Tesla...
Are you saying you think dualism has some persuasive explanatory power?
Tesla is a "lifestyle" company... like apple. Think about how they're acquiring solar city, they have the powerwall and solar panels. They want to use their equipment to power your home/vehicle. If you're a tesla consumer you're at least upper middle class and care about the environment.
Agreed. I tend to cringe at essentialism, which can be applied to any concept. At the same time, I cringe at its opposite. If the idea of an unknown entity is not entertained, held in suspension as it were, in one's mind, I think that theory suffers.
As you point out, "practically predictable" is where I would stand. Or "random enough".

It might seem small, but it's a big step in the right direction. Every block/report on a user/tweets could be rolled up and adjust a spam/abuse score for that user. That would allow twitter users to set a threshold for users that show up in their feed (tweets blocked for that user, akin to google's safe search).

One challenge of this is attempts by groups to harm a user's score by blocking/reporting non-hate/spam. This requires a block or report to be weighted by the blocker/reporter's credibility. It's definitely doable, * Warning Shameless plug* a product I've worked on https://www.inversoft.com/products/profanity-filter handles these situations well. Without some type of credibility tracking it's usually incorrect to blindly trust reports/blocks.

Trump has proposed a lower tax burden on small business owners. This will make it easier to start a company and give many businesses a way to hire more employees.

We should be concentrating on ways to bring more businesses into the US and less restrictions/lower taxes is a great start.

I am only making a point that concepts/ideas are not the same as technologies, and shouldn't be treated as if they are. It's gotten so out of hand now that I half-expect people to start attaching version numbers to them, like "NoSQL 2.0". It's as if the phenomenon of a "technology buzzword" has been totally divorced from the technical product the buzzword is supposed to refer to, which is frustrating.

If I have a resume full of concepts/ideas and no actual technologies, then the fact is that I can't be trusted to extend or repair any real system. The beauty of open source is that I do have skills I can take from company to company. I can use my Rails experience at one company to hit the ground running at another. If we start replacing actual technologies with mere concepts in our trade, then we still have a shared language but no shared skills. So the end result is eventually the same as if open source never happened and every programming environment was proprietary. End rant.
