how is this sustainable in the long term?

if the energy companies are paying their customers, won't the companies run out of money eventually?

and if they run out of money, then won't they have to be subsidized by the government? and if that happens, isn't that basically people paying taxes, which go to the electric company, which go back to the people?

i cringe every time i see "machine learning" and "ibm" in the same sentence. it's not because ibm research is subpar (if anything, id consider them second to none) but because their marketing efforts represents everything wrong with the current ai cycle - that is, selling magic beans to nontechnical and helpless buyers.
Ask HN: Should startup founders read hacker news?
Should startup founders read hacker news as a benefit? Or is it no more beneficial than Facebook, twitter, reddit or another time wasting website? Did Drew Houston, Alexis Ohanian or any other great cofounders read hacker news and benefit from it? Or did they simply keep their head down and work?
Advocate-of-the-deviling re: don't bother encrypting them. Your argument is sound (the reasons why password encryption matters mostly don't apply to API keys), but there is a subtle advantage here: the amount of time it takes you to detect compromise isn't zero. Got a backup on a public S3 bucket? That's bad, but now at least you know you don't have to audit every user action, too. Since they're already high-entropy they can't be enumerated so you don't have to use an expensive KDF like scrypt or bcrypt, and you can get away with just a hash or a regular KDF. (Doesn't hurt to use scrypt though.)

Just to keep myself honest: I'm aware that HMACing with the API key (a suggestion I defended in a different comment) and storing the API key with a KDF mutually exclusive and that might seem like I'm giving contradictory advice. My specific recommendation is still to just use API keys stored plaintext server side just like 'tptacek is. I'm just saying that these alternative suggestions aren't silly.

TL;DR: plaintext API keys are fine and you should use them but you're not a bad person for wanting to hash them :)
Yea, acknowledged, though I still think it would be harder than you might think for the US military to take over the civilian world. Though I still posit that just because your opposition is extraordinarily well equipped isn't a reason to give up the only advantages you do have.
Electric Imp is another alternative, though I'm biased ;)

A bit better at scaling than particle in my opinion, not that that really matters for little diy one off projects though.

Advice from the Best Angel Investors in the World (producthunt)
I don't doubt your story, but modern CPUs can perform AES-GCM at gigabytes per second per core (5GB/sec on my laptop). Disk encryption is a different block cipher mode, but it shouldn't be much slower. So if implemented correctly, encrypted swap should not slow you down vs unencrypted swap. If in your setup encrypted swap is much slower than unencrypted swap, it's a bug in the kernel crypto and it should be fixed.
Physicists Demonstrate How to Reverse of the Arrow of Time
The most important outcome of decriminalization would seem to me the restoration of the right to grow it yourself as organically as you like, especially in your own home or garden just like any other vegetable or landscape plant. Nobody should lose sight of this objective, any progress is a step in the right direction but momentum must not be lost if the type of freedom that made America great is to be recovered.

Too bad your 21st century technologists were so proud of their expensive equipment and low detection levels achieved somewhat through past environmental "concerns" and one-upsmanship that the consensus resulted in regulations too close to the MDL to be more economically feasible for all concerned.

In the 20th century when urine became regulated, the newer labs having the lowest MDL's instead deferred to the older operators having earlier generations of equipment and MDL's about 10x as high, in order to respect their desire to continue to stay in business without an unsurmountable capital expenditure.

This approach has proven better in 20/20 hindsight.

Regardless, pesticides do make possible commercial operations that would otherwise not be feasible, and you can at least wash other types of vegetables before use.
I don't disagree with this, in fact I've thought about it quite a bit myself in the past. I currently do eat meat, but I try to limit to only ethically treated sources.

Some interesting questions I was asked at one point (not a troll): is it moral to eat plants? Why is slaughtering them any more moral than slaughtering animals? If you say that plants don't feel pain, how do you know (Science is constantly advancing and completely turning over something we used to think we know)? Another (inflammatory) question I was asked, if killing animals is wrong because they are living creatures capable of feeling pain, doesn't that make killing unborn fetuses wrong? We know they feel pain.

Not necessarily expecting an answer, but those are questions I've been pondering for some time. Figured I'd share in case there are any philosophy nerds out there like me.
My one off comment doesn't really do justice to how I actually feel about the issue. I'll explain. No one should feel obliged to work for less than what they're worth. This is something my wife and I talk about lot actually. I just have a strong distaste for the hyperbole used when someone does suggest that someone else work for less. Particularly, if the person being asked to give something up has so much to begin with.

To address your example about surgeons. Perhaps they wouldn't need to same amount of "wealth rewards" if somehow we made it cheaper for them to become surgeons in the first place? Could the cost of their training be addressed? Changes to how malpractice insurance works?
> Cars are great for transportation and have enabled humankind to travel further and more often then ever before, but they are also 2000+ lb. death traps and combined with alcohol they are an absolute threat to everyone's safety.

The time savings provided by cars, once you factor in time spent to pay for them, pump gas, perform (or wait on) maintenance, plus actual travel time, is dubious for anyone earning average income. I've run the numbers, and even for me earning way over, it's practically a wash versus a bicycle.

Then consider its effects also on distances between things and how many people are now dependent on cars (=less free), and it's not hard to see widespread ownership of automobiles as overall a very negative force in society.
This point makes me wonder whether Facebook, Twitter, Reddit and other such sites are simply fundamentally unworkable ideas:

> We are biological organisms with thousands of years of evolution geared towards villages of 100, 150 people. What on earth made us think that in the span of a single generation, after a couple generations in cities with lots of people around us but wherein we still didn’t actually know that many people, that we could suddenly jump to a global community?

The reason so many problems occur on them (brigading, uneven rule enforcement, the feeling that Nazis/antifa/whoever aren't being banned, etc)comes from the fact they're a million communities built on a platform run by a single organisation, and attempt to have groups of people who simply can't work together use the same platform and interact with the same user accounts.

They're trying to be a 'global city' inhabited by millions or billions of people, and are encountering the same issues every country or organisation does at that scale. On the other hand, old school internet forums and separated communities were like human villages of a few hundred people, self contained instances that could be run according to their inhabitants wishes and meant that those that couldn't interact civily for some fundamental belief difference didn't have to.

That seems to be a case where Zuckerberg and co were wrong, and where that's caused huge amounts of people to numerous people.
>I don’t think anyone saw coming that we’d have to actually be explaining to American children why racism and fascism are bad in the 21st century.

For me, this is the most damning sentence in the whole piece.

Before Eternal September, there were exactly as many racists and fascists in America, it's just that the mainstream media had done a fairly good job of hiding them. If you lived in San Francisco or New York, you'd have to make a real effort to see the level of racism that was still prevalent in many parts of the US. The sort of people who built the internet didn't know what they'd unleash, because they had been born and raised in a bubble.

The internet hasn't fundamentally changed human nature, it has just exposed what already existed. The average person is pretty awful and half of them are worse than that. Timothy McVeigh wasn't radicalised by the internet - he was radicalised by photocopied zines, small-press books and conversations at gun shows. The internet may have accelerated that process, but it has also brought it to light. It has shown liberals that they have been utterly complacent, that for decades they contemptuously ignored most of America, that they lived in a fantasy of their own making.

A mea culpa from the pioneers of the internet is missing the point entirely. The problem isn't that we built a communications platform and learned that a lot of people held abhorrent views, it's that for decades we ignored the rot at the heart of American democracy.

As far as I know most people are just curious (I saw my first black person when I was 11 years old, so yeah, mostly white country). There is racism, sure, especially in less-developed parts of the country, but most people just keep to themselves and don't ever express their racism. I also don't know of anyone below 30 to be racist. It's mostly old people from the soviet times (where there were virtually no people other than of colour white around).

Perhaps, but its easy to be outraged at people in both hindsight and outside of the situation they're in.

It looks like you didn't get the joke.
Negative prices occur all the time in the US. Not every day, but often enough when load is low and the wind is blowing. As more and more renewable are built, this will occur in increasing amounts. We still have to have non-green generation online as wind and solar can massively fluctuate. For the time being, the state commissions help out the utilities via legislation and increasing rates. This isn't some conspiracy, but what you do if you want available power 24x7.
Believable.
> But over a couple centuries/millenia, I wonder if polygamous societies would wind up as a race of smart-hard-working-competitive-assholes, in comparison to us monogamous dolts.

this has already been happening, if you compare western monogomous societies to islamic polygymous societies.

there are plenty of smart-hard-working-competitive-assholes in both western and islamic society, and there are plenty of dumb-lazy-nice-guys in both islamic and western society as well.
The companies here (not Germany) can afford to pay for the right to put electricity in the grid because they are guaranteed a fixed compensation by the state for all the renewable electricity produced – at a rate that's several times the market price. Thus even at times when they have to pay, they still make more money than if they shut down the plants – which itself would just cost money.
It was easier in those days to find NOC phone numbers and network engineers generally like to fix problems.

I did network event correlation in those days (using prolog and Perl to convert hundreds of thousands of log entries and events to actionable alerts), and would call various NOCs all of the time, usually to let them know that their device was spewing alerts or doing something dumb. There was very little in the way of authentication. Once you crossed the line to ask for things vs fix things you’d get more questions.
Based on the results of the grid battery system in South Australia it looks like this is the next step for Germany.

Add the batteries for peak smoothing and then you can start to take off the more problematic (carbon foot print wise) base load sources.
This is theoretically perfectly feasible. Currently, however, the capital costs of mining equipment are so high that it doesn't make sense to keep them offline.
Long-time OpenBSD user here. OpenBSD has sane, secure defaults with nothing enabled in a fresh install. This is a desired default, as everyone uses OSes for different reasons. OpenBSD makes a phenomenal firewall, a pretty good Web server, and a super nice, secure file server.

OpenBSD shines because of the ongoing code audit, the minimalism, and the ability to easily make it into whatever you want. I don't care for any other OS for serious business. I will almost always use OpenBSD for servers, with RedHat or CentOS being the only other choice because of SELinux.

I would also venture to say that OpenBSD has the absolute best documentation of any OS out there, even better than FreeBSD.
That would be much harder to fly under the radar because fingerprinting is what you do to people who are arrested. People wouldn't put up with that so easily.

There's been some rumblings of the "uniqueness" of fingerprints being far less than you'd think. Fingerprinting everyone who flies would just produce more false positives. The people that's bad for overlap a lot with the people who stand to benefit from invasive security theater.

>long-range mesh capabilities for its Wi-Fi standards

>go through buildings over 1 mile even at 1Mbps speeds

That sounds like a nightmare. WiFi is already nearly unusuable in high density situations. A recent trip to help a friend living in a medium density part of a large city showed ~100 access points, using the lousy WiFi antenna on my smartphone. Even every single 5GHz channel (which really doesnt travel well through objects) was taken, usually twice or more, including all the DFS channels. Mind you, this was inside.

I cant begin to imagine how unusable WiFi (and its related unlicenced spectrum) would become if had 5x the range. Even in low-density suburban areas, 2.4GHz is crowded to the point of degraded performance (although 5GHz is pretty clear for now).

Is that another way of saying "the bubble hasn't burst yet"?
You and OP have the same mistake - you trade exchange, when you should trade margin.

In trading exchange bots will lose in unregulated market. Only the best bots can benefit where insider information is a common thing.

In margin trading however what you do is extend your overal capital, i.e. by having 10k usd you can make profits of holding 10k and trading 100k (at 10x margin). However of course margin is more dangerous but nevertheless you'll most likely end up with positive in the long run.

If your SDK is meant to be used as a binary framework or in any sort of compiled form (which is probably unlikely because you say it's going to be open source), I'd recommend Obj-C, because Swift's ABI is not stable yet.

If your SDK is meant to be used from source, I'd recommend Swift. I'd even say you should prioritize providing a good Swift API over providing any Obj-C API at all (so if the API would work best if it uses enums with associated values or protocols with associated types, so be it, even if that means it can't be used from Obj-C).

You have mentioned the downsides of picking Obj-C, and they are both valid. There are no upsides to picking Obj-C though - Swift is more popular, and can do anything Obj-C can do (because it can piggyback on the Obj-C runtime when required), and do lots more that Obj-C can't do.

The biggest problems with Swift earlier were (1) Xcode crashing or being too slow and (2) the language changing every year. Both are pretty much fixed now.

At this point, the only reason an Obj-C expert would stick to Obj-C is familiarity - it's faster to code in a language you got to know well over many years. That's however not a reason for _your_ SDK to be in Obj-C.

Fellow NYC home owner here. Recent one, though.

What are ways in which people are telling you to live?

I'm looking forward to the 3X price jumps of businesses in my neighborhood - it might improve the quality of the food and options. I say that entirely with a straight face - since almost all the food options are 'affordable', the food options are greasy, unhealthy and also lacking in diversity.

My take is, everyone has a right to try to 'make it.' People don't need to take note of how the community was 5, 10, or 50 years ago as the city is continually changing. Almost nowhere in NYC is a neighborhood static in terms of pricepoints, culture or just about anything else.

I think it's reasonable for people who have lived decades someplace to want this preserved, and it's equally reasonable for new people to come in with new ideas.

It's a zero-sum game and so the law has to view these things without biasing any group as much as possible.
Ask HN: What's the best way to recover from burnout?
I've been in a technology executive role at a large company for 6 years. It's been incredibly fulfilling and the best job I could ask for. In the last couple years though, it's also pivoted a bit and become increasingly draining. Because I can affect my circumstances and mitigate the bad parts, quitting has always felt like giving up, so I've found ways to continue. But I've now reached the point where I'm so burned out that I have very little ambition, and find myself just trying to get through the day, avoiding opportunities and social interactions. I've decided I need to quit.

The problem is, I can't imagine what I'd like to do next. As I mentioned before, this has been a fantastically fulfilling job and a promising career. Nothing I can imagine stacks up to it. At the moment I want nothing to do with it, but I think that's fueled by my burnout. If that's the case, it seems silly to switch to a different career. How do I get past this burnout so I can think clearly and be "myself" again?

Best idea I have is to take a couple months off and try to recover from my burnout, and hope it becomes clear what I'd like to do next -- even if it's a similar role at another company. But taking time off with nothing lined up has its own risks, and I imagine there's more to it than simply "not working."

Any advice?
This might end up as a "nature vs. nurture" question.

The flip side of this argument, is that in modern monogamous societies (especially with birth control enabling easy family planning), the smart and industrious couple will probably have the ability to devote more time and resources to the relatively small amount of children they have.

Whereas, the smart and industrious polygamous male (traditional polygamy tends to almost always be patriarchal)'s resources will be spread more thinly among their X wives and Y babies.

At present, I'm not aware of a current polygamous society that is known for technological or intellectual sophistication. In addition to the above, the overall social structure in polygamous society seems to be negatively impacted, owing to the large quantity of unmarried, potentially violent, men that need to be dealt with somehow (as alluded to in The Economist article). Consequently, I'm also not aware of a polygamous society which embraces liberal values politically, or embraces democratic style political structures.

In other words, from the evidence I see, it seems likely to me that the negative consequences of polygamy wipes out any potential genetic benefit.
I was one of those people tasked with investigating Watson and I had the exact experience you described. It was a huge joke. Tried out Bluemix as well, it wasn't a huge joke but it wasn't great either.
I totally agree that discrimination is done by geographical area of origin instead of colour of skin. Lots of Estonians have an axe to grind with Russians (due to history), but I don't know of any other people that we tend to dislike. Perhaps British guys that come here to get drunk and yell and piss all over the streets, but I'm sure that's a problem most everywhere.
Batteries simply don't really exist to store grid level amounts of energy. You have to stack lots and lots of batteries which costs lots and lots of money and still only stores something like ~10 MW when we have 1500 MW coal plants. Electricity is used immediately, so we really can't economically store it in the levels we need. In the future (this is just starting to occur), large batteries will charge (as a load) when the price is low and discharge (as a generator)when it is high which allows the owner to make money and helps the grid as these resources can provide power nearly instantaneously. Right now they're small and few in number, but they will get bigger and more prevalent assuming battery technology continues to get better.
