Ultimately, trust.

1. The developers. I have more confidence in the implementors of, say, Linux kernel, than in developers of, say, Chrome or Firefox or Safari.

2. Testing. Kernels routinely handle successfully vastly more corner-cases than web-browsers. [Yes, I see upon all of current Linux, Windows, etc. installations as continuous, live, in-production testing.]

If kernels were as shabby as today's browsers, nobody would use them for anything but toys. On the other hand, try to find a person who gets genuinely surprised when a web browser crashes.

I don't think you understand correlation. For crime and milkdrinking to correlate, criminals would need to drink more (or less) milk than non-criminals. A better example would be: umbrella-carrying and windshield-wiping tend to correlate, but they are both actually caused by a hidden factor: rain.

> it leads to conversations like cutting down on recreation and leisure and reducing spend on hobbies and downtime

Very good points and I agree with all.

Regarding recreation - I do very well and that conversation can still pop up. My wife doesn't have any hobbies and I have quite a few. I recently got into kayaking so there's a decent upfront cost. She'll make remarks like we need to cut back on spending or you're spending too much, how much was that, etc.

I just tell her - I could cut back on hobbies and spending but that would require me to cut back on work or abandon one of my companies. Then she gets quiet because she knows what that means. :) I also worked the health benefit angle which is always good with wives. She knows I'm going to spend however I want anyway but I try to get her to understand my reasoning and what the benefits are vs the cost.

It's important to enjoy the fruits of your labor and have fun, it's important to have hobbies, and it's important to get exercise.

Certainly you shouldn't spend wrecklessly like some people (take out a HELOC and buy crazy things like dune buggies like so many did in Vegas prior to the collapse), but every couple should save a set percentage (ideally 10%+) and have a discretionary budget. That way you don't get all the passive aggressive remarks and arguments when one of you spends money on themselves. It's already been decided.
Nice idea, but this is pretty difficult as a screening question. I could simplify it by letting the candidate assume that there are no repetitions in either array.

This is just a press release about the actual scientific publication. The abstract provides more information:

https://www.nature.com/articles/nenergy2017143

Cooling systems consume 15% of electricity generated globally and account for 10% of global greenhouse gas emissions. With demand for cooling expected to grow tenfold by 2050, improving the efficiency of cooling systems is a critical part of the twenty-first-century energy challenge. Building upon recent demonstrations of daytime radiative sky cooling, here we demonstrate fluid cooling panels that harness radiative sky cooling to cool fluids below the air temperature with zero evaporative losses, and use almost no electricity. Over three days of testing, we show that the panels cool water up to 5 ∘C below the ambient air temperature at water flow rates of 0.2 l min−1 m−2, corresponding to an effective heat rejection flux of up to 70 W m−2. We further show through modelling that, when integrated on the condenser side of the cooling system of a two-storey office building in a hot dry climate (Las Vegas, USA), electricity consumption for cooling during the summer could be reduced by 21% (14.3 MWh).

The Arctic and Antarctic are very big. If you could somehow build a structure that would withstand the harsh conditions, I imagine using a mirror or even aluminum foil would be an overwhelmingly cheaper way of reflecting energy back out.
This isn't purely a software engineering mess though. The PC architecture for "off" is a mess at the hardware level too.

I mean, long ago you just had a physical switch on the power supply. But then filesystem authors invented buffering and that wasn't safe anymore. So now there were two ways to shut the machine off: the "safe" way and the old way (where the "old" way was still available via e.g. holding the power button down for 4 seconds).

Then, we wanted to start using laptops and carrying them around. But booting the whole computer again and again every time you changed your seat became a chore, so software people invented this cool new trick where you could dump memory to disk and restore it later, so "hibernation" was born and we now had three ways to shut down.

Then the hardware people jumped in and pointed out that really the problem here is just the CPU. DRAM refresh is cheap, so there's really no need to dump the RAM at all. Let's just shut the CPU off and come up with a hardware/firmware/OS/driver hack (yeah, it touches basically everything) for powering on into a known DRAM configuration. Much faster! And now we had a fourth way to shut down.

(OK, this is a little spun. In fact suspend to disk and suspend to RAM landed nearly simultaneously in the PC world, with different manufacturers picking different horses. Then of course ACPI came in and standardized both, forever locking us into not one but two kinds of suspend.)

Then of course, we had a paradigm shift where "mobile" OSes revisted this whole scheme and threw it out the window. The hardware people making mobile chips designed the clock and power gating logic such that the "suspend to RAM" happens essentially every time the CPU reaches an idle state, and never has to be "entered" explicitly the way ACPI S3 is. And now PCs are shipping with this scheme too even on systems where ACPI still works in a traditional way. So, yeah. FIVE.

I mean, Microsoft surely made a UI mess out of this. But it's not like they were handed a simple problem to begin with.

That is a very revealing article, thanks for sharing!

I think one interesting point the article makes is that parenting really doesn't matter much, except when parents do something extreme to affect the behaviors of their children. I wonder if parents' extreme desire for their children's scholastic success could be categorized as such? Anecdotally, growing up in India, I remember being hit by my parents as a younger kid; the physical violence stopped when I became a teenager, but my parents were quick to show their extreme displeasure and worry when I would get low grades in High School.

Not to suggest that all Asian/South Asian households are violent towards their children, of course. Although, I do trust research over anecdata, so I will agree with you that it might just be a genetic thing.
Wouldn't it be more efficient to just use water run through a coil 6 ft underground? In most areas that have the intense heat that running water over the radiators actually would help, the ground 6 ft below is pretty easily cooler than 5-10 degrees C. The electricity to pump 6 ft down couldn't be that much more either...

And when it isn't as hot out, you can actually use the ground temp to radiate heat out of the house by itself, no need for coils and a fan to run in ambient air temp, right?
Pre-engineered metal buildings [1] like those offered by Butler are an excellent form of construction for many applications. The components are fabricated using standard processes of the steel industry (milling, extrusion, roll forming, etc.).

To the degree these create a machined building in agreggate, then likewise the aggregate of dimensional lumber, plywood, OSB, asphalt shingles, gypsum board, concrete masonry, insulated concrete forms, etc.

[1]: For what it is worth most pre-engineered metal buildings in the US come from mom-and-pop shops rather than the big players like Butler because engineering is engineering and roll formed steel production is a commodity.

Its easy to reconcile both of these statements. Those that grew up in poor households often witnessed their parents make poor economic decisions. If you make the same decisions as your parents, (possibly because they just don't know any better), then your poverty is still a result of your decision.

We need to focus on education and adjustment, and not on any outside influence. Frankly, I do believe that life can really make things hard, but by focusing on things within our control we can make progress rather than repeating the cycle.

Hey HN,

Me and my friend have been working on a side project for quite some time and I am excited to put it out in the world today. This is a Chrome Extension to help people increase their productivity and focus by 10x. We're doing this by:
1. tracking active time on website(s) the user been working on and showing that data every time they open a New Tab.
2. Nudging users via Push Notifications when they lose focus and start surfing website(s) they define unproductive. See a demo here: https://www.youtube.com/watch?v=mu0ktytoAhc

It's currently in beta and we're going to launch next month. If you like the idea and would like to get early beta access, feel free to subscribe via Product Hunt (https://www.producthunt.com/upcoming/rooster) or from the home page we've built (www.getrooster.in)

Please provide feedback or any insight. HN people always help in more ways we can think of
Even a cubic foot of water would be well under 100lbs. I doubt a cubic foot of mussels + water to fill the rest could weigh a ton.

It may be possible for (especially stationary structures) to accumulate enormous columns of biofouling materials, but for such a layer to reach > 20 feet thick (possibly closer to 50 feet without counting the interstitial water) sounds unreasonable. But I'm not knowledgable in this area.
You assume it will ever be released. :-)
That begins to pan more into the realm of maintaining a good online presence and why I advocate for stronger privacy policies. Online presence simply comes from educating people on what people can see and Privacy policies to dictate what I am willing to release for compensation. Finally, I'm willing to assume the data is somewhat sanitize to remove identifiable marks (again, that's a privacy policy issue).

If we extend the idea of data to include anything - my GPS data from my phone, heart rate via Fitbit, viewing habits; this is all data that we generate. Going back to my producer analogy, image if I was using a "Water-As-A-Service" company (WaaS) to water land I own; mind you, I'm not a farmer, I simply own this 'thing'. Now assume that WaaS has been taking anything that the grows on that land (say 'wild strawberries') without paying me and then selling it for another profit.

In this scenario, I'm upset as an individual because 1) I never gave permission to WaaS to take that product and 2) they are making money off of my hard work - they gave my a tool (water), but I did all the legwork to create the product.

In the same light, change water to cellular connection and strawberries to activity. Right now, we freely give our product away for free, which turns back to the story. I am willing to be compensated for my data. I'd prefer a better compensation model than "3 Months of HBO GO Free", but I look at this as a positive step in the right direction.

Furthermore, it could be used to incentive under represented statistical models. How a Caucasian male uses a system / service is probably a saturated market, but a Native American female model would be willing to pay more because that data is rarer. This can different for data point to data point, but now we're talking the economy of individual data and I'm not well versed enough in how that'd work.

Ultimately, I've accepted that in the current era, my data is out there. All it takes is one bad data breach and the goes any anonymity I've worked towards maintaining. Even to take a more cynical approach, I know Big Brother is watching - its simply too easy to do so. Its not a "nothing to hide, nothing to fear" argument, I just accept it as a consequence if I want to live in a digital world. However, I don't blindly accept this as there's nothing I can do, 1984 Orwellian times, but as a capitalistic viewpoint. I produce something, now pay me if you want it.

I have decided to stick with writing code rather than progress my career.

Consequently I am that minority in the team delivering features that customers use. I take personal pride in that and keep quiet about it. Those reports, those plans, the documentation, the mock ups, the meetings and the emails are not in the final product, all that work counted for next to nothing. Ultimately it was mostly two of us working away and refining the specs by collaboration with stakeholders on an informal basis. Because we understand the problem space we are able to ask the important questions and I think stakeholders prefer working directly with programmers rather than have messages related via management channels with costs plucked out of the air and relayed back.

With stakeholders I find I am talking their language and a lot of ground gets covered in a working meeting, where some fixes are done during that meeting with anything requiring more time speced out. With management intermediaries they think everyone thinks like how they think so they can't imagine that it would be safe to have the programmer talk in a mix of trade jargon with a client. Usually this is part of the gig, many people make a cushty living coasting between meetings. What do we do so as to get on with the job but not enable this coasting that goes on with freeloading management types?
