Allowing flow of power from rooftop solar into the grid isn't free.

The cheapest power to generate is the base load - long running gas, nuclear, coal, whatever. These are plants that take days or weeks to spin up and down and produce the most cost effective, efficient power. Since supply on the grid must exactly meet, always, these efficient plants can only be used to provide the base load - the amount of load below which the grid never drops.

Any power required beyond the base load comes from generation designed to be used periodically. It's not as efficient. There are stages to this too - you can have generators which take hours to come up which are more efficient than those which take minutes.

Residential power generation can cause the base load to drop, and require more peak load generation, increasing the production cost of power.

The power which customers generate must also go through transformers, rectifiers, and all that good stuff to be usable by others, and that equipment isn't free either.

Whether the company buys in wholesale quantities doesn't really matter, since the costs incurred from supporting residential net-metering aren't zero. It makes sense that they pay less for power they buy than what the sell, otherwise, that cost is shifted to someone else.
So the original idea for this was that I wanted to find quality gyms in my area with vast arrays of equipment. I specifically disregarded globos like Planet Fitness and WorkOutWorld, which have shady contracts and terrible policies.

So my initial feed was the 3500+ Crossfit gyms, plus an additional 600-700 powerlifting, weightlifting, and strongman gyms across the country. I knew these places would have great equipment, great staff, and the amenities fitness enthusiasts would need to get in a great workout.

That said, as you can see, Crossfit dominates more than 80% of my current results. If you sort by Price you may find a smaller, niche gym in your area that will likely be much cheaper and will accommodate your workout type.
Is on my list now, thanks :) In general, CloudRail is community based. Means everybody can add new services to the system. This feature is currently in closed beta. If someone is interested, there is a button to apply for beta in the workbench.

It doesn't matter from a business side of things, but since this is the Hacker News community, and not a fitness enthusiast community, I wanted to have some common ground that would be interesting to the HN community :)

Alphabet companies are more like business units, with all the associated bureaucracy and overhead, than startups. Think more GE than YC.

Meh. I don't see what they could do with it... Industrial espionage maybe, but it's not exactly new tech. The reason people buy missiles from the US has more to do with the cost of setting up weapons production infrastructure than not knowing how to build laser-guided AGMs.
You do, although don't get too hopeful for better schools. It's true masters is easier to get into, but as a current international masters student in California, I can say mean GPA and test scores are still high.

(Source; I have been working on the next generation of auto insurance risk models for the United States)

Car (really, driving) insurance is heavily regulated by the government, each state has agency over what information insurers are allowed to include in their risk models, as well as actually auditing the risk models themselves. Insurance nomenclature will refer to these inputs as risk factors. You can get an overview of the rules in California from the Insurance Commissioner's office here [1], and you should be able to find similar overview for your state by googling "auto insurance risk factors <state>"

Usage-based insurance (UBI) is the most recent innovation to be approved for widespread use. It's actually been around for a few years (at least 2012), this article's relevance is mostly about the incorporation of UBI data-gathering sensors directly into new vehicles. The key risk factors UBI focuses on are miles driven, and extreme acceleration/deceleration events. These factors were chosen because they can be easily measured using existing data ports on older vehicles [2], amongst other reasons. The San Francisco-based start-up Metromile [3] is one of the industry leaders.

Ultimately, UBI is limited in that it focuses exclusively on factors specific to the vehicle. As many commenters have identified, "risky" driving behavior is a both a function of how you drive, and how the people around you are driving. The latter effect is much, much harder to capture, but the US Department of Transportation is already engaged in R&D to identify potential risk factors that could be used within the existing regulatory framework.

With the rise in "semi-professional" drivers via on demand ride-sharing services, changes in ownership models via car sharing services, and the rise of semi-autonomous and eventually autonomous vehicles, the mechanics of automotive insurance are going to change a lot in the next few years.

> The sheer scale of the evidence is overwhelming.

Really?

Because your description sounds very flimsy. Can you really compare Japan and the UK without correcting for a bunch of confounding cultural variables that have nothing to do with equality?

Is there no society that is "more equal" than Japan, and yet scores terribly on the metrics you suggest?
Most of problems of inequality come down to the fact that rich are allowed to invest into land / housing.

One can argue if enormous capital gains should be taxed or not, but the problem starts when rich park their money where it inflates "normal people"'s necessities.

Best jobs are concentrated in few big cities, workers have to live there. Rich don't have to live there but they corner the housing market in order to extract maximum percentage from workers' salaries.

I don't care how much money the rich have as long as they don't inflate the housing so I can afford to buy my own.

Capitalism has learned to extract more surplus value from labour about the moment when worker productivity and salaries started diverging. It used to be that the rich are very few and once they bought all the London property normal people could live their lives. Nowadays there are so many foreign billionaires (China) who either have money or can access cheap debt that they can corner property market in every major city.
That is what is so unsettling about T-symmetry. What you describe is merely improbable, not impossible. With appropriate starting conditions, it is certain. Basically we'd require all the particles in the comet to bounce into each other in such a way that their heat motion cancels and organizes into momentum in one direction, away from the planet. This is physically permitted in either time-direction, but we only see it in one.
It uses some examples like

.search-form {

which generates this:

which can lead to some performance issues :)

That's why I suggest the non-nesting approach
Ask HN: Number 4 employee, should I exercise my options? Form 83(b)?
Just joined my first startup. It is seed funded and I think it has the potential to be massive. I'm employee number 4 and was given a substantial number of shares.

According to the fair market value, if I exercised my shares I'd have to pay the company $15,000. I am not willing to risk the cash today on something so speculative. From my understanding, if I were to exercise later I would have to pay the AMT at time of exercise. If I exercise now or before the next 409A, I can file a form 83(b) election and then just pay long term capital gains when I ultimately sell those shares.

The founders seem very reasonable and I'm trying to figure out what my options are. Any advice?
The moment my dad said his only worry for me was making sure I was able to learn and handle being responsible for myself and responsibilities I'd have for my life including others.. to realize I had already been doing it for a bit.

Beyond that, I think as an adult it's a critical moment to realize it's not about what you get from the world, but what you are able to give, and your ability to think about others as much as you think for your self is critical when you have to work and function with any combination of working in the world, relationships, family and kids.
Boy, I don't. I find it repulsive. I'm naturally a "deep learner" by that classification system, but the author of that blog seems to be implying that everyone has a choice in the matter, which does not match my observations.

If it's actually true that people can be divided into those categories, it would be interesting to look more deeply, to understand why people differ in this way. Otherwise, you're just pointing at yourself and saying "look how smart I am!"
>selling people

You say that like it's even remotely comparable or germaine. A big fat red herring is what this is.

Returning to the point, you may not like it, but the law says it's legal to set up sting operations by serving child pornography. The ethics are certainly debatable, but you have your answer as to why it's being done: CP is a commodity, not a physical person, and that's fair game for law-enforcement in the same way as guns, drugs and blood-diamonds are fair game.
Cool! I like that project, how did you source your feeds - directly from Google Places?

>As I understand it, Verizon has historically had the strongest presence in the low frequency range,

Yes this is correct, and the reason they have this 'monopoly' on the low frequency range is because Verizon has been the most shrewd at getting the government to grant them licenses for this spectrum.
The Problem with Your Performance Review
It's down for me
"This is the end result of an education system that has not prepared people for the modern world, if we engineer a solution that produces water of a purity greater than water from a reservoir and and half of people are still not sure it is safe to drink then we have a massive problem."

It has nothing to do with the education system and everything to do with human social evolution and evolutionarily stable strategies.

You're looking at the problem "like a nerd"[1] wherein you have a fixed set of definitions and guidelines and the end product (the water) fits or exceeds all of them and therefore, presto! Anyone who disagrees with your framework is therefore an idiot.

But these people aren't disagreeing with the stats - they don't care about the stats. They have a built-in, knee-jerk revulsion to drinking anything that came from sewage. That might not be rational or useful in 2016, but it has been tremendously useful over the past hundred thousand years of human social evolution. In fact, so useful, that people without that revulsion have been heavily selected against.

If your response to this is to show them more and more data and "proof" you're missing the point.

I think I'll disagree about Gates. I know you remember him more from his Microsoft career - I was young enough then that for me he was just a boogeyman used by Linux fans to justify their self-perceived superiority, etc., so we have a difference in perspective. The Gates I know is mostly the Gates of today, and it seems to me that he's both incredibly driven and finally found the moral compass. From what I know, he and his wife are now doing great work for mankind, and they're incredibly smart at making it as effective as it can be. Does this offset his sins from the past? I don't know. But I applaud what he's doing today.
Most opponents of systemd are not against consolidation and standardization of linux system administration. What they object to is the development approach and happiness to introduce bugs and unbootable systems.

To add one more anecdote: give voidlinux a try at some point. It uses runit as its init system and boots at least twice as fast as a systemd-based arch linux system. As with startups, the idea is less important than good execution, and systemd only succeeded on the former (so far).

With all that being said, I do like that I know how to do common administration on both Arch Linux and RHEL and Debian without learning three toolsets.

Is this just a gut feeling you have?

The power supply curve from solar is going to correlate highly with the air-conditioning load that'll drive the peaks in Nevada. Peak shaving is a big business because the energy at the peak is (by far) the costliest to generate. Just a customer supplying their own household power from solar power will be saving the utility money at peaks, sharing the excess with nearby customers even more so.

You are of course correct that they wouldn't get this deal if they where unregulated. The way you say it might fool people into thinking that minus regulation a utility would be a great example of free market competition, rather than a Monopoly (or a Monopsony in this particular case). So I'm confused why you bring it up? That's like talking about a business deal and saying if this was a Mad Max style post-apocalytic wasteland then you wouldn't offer as much. Of course not, you'd just take it from them at the point of a gun. What does this say about its actually value though?
The non-monetary resources provided to YC companies are mostly freely available to any company (startup school, how to start a startup, pg's blog, sama's blog, AmAs, etc.).

Sure, you could argue that being a YC alum helps you raise that first round, but even YC companies that raise smaller-ish rounds fail all the time.

I feel like people think if you're in YC you're a sure bet. That's not the case at all. First and foremost you need a product that's going to be better than anything that currently exists. At the end of the day YC is just an angel investment firm with a great track record.
The numbers here always amaze me. Would they be better off keeping Yahoo going than, say, investing $20bn into the next generation of startups?

Just imagine a $20bn seed fund and the type of companies that could be funded. Startups in more difficult industries that need a larger upfront investment (genetics, pharmaceuticals, aerospace, etc.)
Many people think Musk is in the top percentiles of "using money well." While I think it is always appropriate to want the government to run better, it's probably not fair to set such a high bar for it.

One might just as easily say "no VC should invest money in any company whose founder has a poorer track record than Elon Musk" which is of course a ridiculous posture.
Depending on the complexity of the SVG (e.g. scribbles on top of scribbles), rendering SVGs can be very slow. If the SVG is not changing, it makes sense to render it as little as possible. I am doing the same thing with a d3 project, where the browser has trouble redrawing 50k elements.
Yes, both of those will be added!
>It's very unlikely for a volunteer programmer to wake up with the irresistible desire to "hunt for memory allocation bugs in OpenSSL to prevent heartbleed".

Honestly, I find that kind of work fun. The problem is one of incentives, in that features are more highly valued than unknown bugs.

I certainly don't know Rust as well as C++. Some other fellows in this thread provided some features in C++ that you can't learn about in Rust, fyi.
I've seen rust compiler bug once and that was long before 1.0. The only issue now is that some important API's are not yet declared stable (RFC still being open), so many 3rd-party libraries target nightly and won't work in stable. This is however matter or 1 or 2 releases, and proves that rust developers take this matter seriously and don't wont to stabilize anything they aren't 100% sure.
For all practical purposes rust is usable now, and more and more people are using it - certainly more then 3. Generally looking at rust projects on github,
most of issues are feature requests. I don't see issues with crashes or panics,
while I know plenty for similar projects written in C, at least in their early days.
Sometimes I wander off anyway.

I'm just curious. Is there any particular reason for focusing on the iOS SDK first? With the node SDK, one could immediately start work on server side applications, and potentially leverage tools such as browserify and react-native to start building applications on the web as well as iOS?

5 secrets for mobile app success from top design firms
I feel like Yahoo would be best broken up into lots of tiny pieces which would have the opportunity to become little independent start-ups in their own right, taking whatever "bit" they have and turning into a new concept and building a business around it. They need that injection of innovation and modern startup mentality which probably won't happen in a monolithic behemoth where everything is lumped together.

I'm approaching 40. I've never been "aimless", and while I can definitely increase how often I take responsibility, I'm doing well. I own a house, am married, taking care of my mother, employed, socking money away in a 401k (probably not fast enough, but it's happening).

...and I've never felt like an adult. I can have the weird dichotomy of having friends young enough to have missed everything I relate to my childhood, friends that I consider "adult", and yet I still feel like I did when I graduated college.

I have talked with CEOs and VPs or just other coders that are younger than I, yet I "feel" like they are older, more experienced.

I have no idea when I'm really an adult, but I don't expect it will be soon.

It could be easily argued that the promise of bitcoin (blockchain) will contribute way more to the betterment of humanity than anything ZenPayroll will ever do (I like ZenPayroll, don't get me wrong). But regarding bitcoin, the argument for increased transparency (public ledger), reach to 3rd world consumers who do not have access to a stable financial system, reduced overhead and costs of existing global financial systems etc. are very important and worth the time of smart, talented founders.
