One reason the site guidelines ask you not to complain like this about downvotes is that often, by the time the dust settles, people have given more upvotes. Then in addition to being off-topic, the complaint is misleading.

But these collections have more meaning outside of America where books get banned (ie. Britain, Australia), but libraries still need to record the historic and intellectual value.

Look up "anti-islanding". If the grid is down, you can do whatever the heck you want with your own wiring, but back-feeding power into the grid is a very firm no-no.

> Islanding can impact utility asset integrity. For example, these conditions can interfere with manual or automatic reclosing, or loop feed automatic switching on the radial distribution system. Utility assets incorporated into or reconnecting to an island with abnormal voltage or frequency conditions may result in extensive equipment damage, for example, a line recloser damaged by reclosing out of phase or lightning arrestor damaged due to abnormally high voltages.

> Public safety risk may increase on delta connected systems. For example, a downed wire can remain energized after a device opens to isolate a fault. Depending on the location of the DG installation and the impedance of the downed wire, there may not be sufficient fault current or voltage deviation to trip a generator offline resulting in power being provided to the downed wire.
My Writing Tech Stack
I would say that about my last company. I was director of engineering and it was torture having to deal with so many meetings, opinions, status meetings, and planning spreadsheets. That I could deal with if we could actually get anything done, but it was made worse by the politics and fighting. The manager meetings were like toddler tantrums and usually ended up with someone (never me) screaming and running out of the room. The best part was when the CEO tried calling me out for lack of leadership for trying to be friends with all the engineers. I reminded him that my team was the only team in the company that had not lost any members in 2 years, and our meetings never ended in tears. He hated me for that, and in the end I quit, wondering if it would get better after I left. It didn't...there were massive layoffs, and the latest news is that they are trying to liquidate the company.
The rebellion against pay-walled research publications really needs to be holistically supported by all researchers. The big problem is that lot of "good" journals have also pay-walled publications that they pay nothing to authors but charge ridiculous amount per publication. This includes big names like Nature and several publications of IEEE.
> If a testing plan was going to accelerate the adoption of autonomous cars which are twice as safe as human drivers by one month it would save the lives of approximately 40,000/2 / 12 = 1,666.6 people.

This is being overly generous with the assumption that self-driving cars will be safer than human drivers, to the point of being potentially dangerous.

I say potentially dangerous, because this generosity in your hypothetical is being used to justify deaths that need to happen in order to stop nebulous deaths in the future with technology that might not be as safe as your hypothetical assumes.

I think l9k might have been making a more subtle point: maybe motivation/willpower isn't quite so different from the other required personal attributes (in this case, physical fitness) as we tend to think. Perhaps because it can't simply be switched on and off like a tap, but requires training analogous to physical exercise; or perhaps for deeper reasons. (Going down this road pretty quickly leads us into a thicket of ambiguities and philosophical puzzles around 'free will', so it might not be very productive, but it's still worth bearing in mind occasionally.)

Where I live the busses cost about 400K in capital costs and last about a decade. I don't know the maintenance and fuel costs but a reasonable guess would be 30K / year. The drivers cost about 100K in total compensation.

So driver labour is a huge component of bus cost. Self driving systems should have a capital cost of about the same as a driver for one year.

Jeff Han: Unveiling the genius of multi-touch interface design (2006)
Really impressive. I've thought about some of this problem before but clearly I wasn't thinking large enough. The best ideas are like this - obvious once someone else showed them to you... but still hard enough to be fun to do.

Clearly you have a long path ahead of you. I am curious about several things - serious curiousity here!

It seems like you have to design the circuit blocks before this thing starts its build. The LEDs require a resistor to set current, the micro requires frequency-setting resistors and numerous caps, etc. Presumably you are still reading the datasheet to do the block design.

- How well do you follow manufacturer layout recommendations? For something like a switching converter, following these guidelines can be the difference between a working system and a smoke generator.

- Can you tune your system to make tradeoffs against these layout guidelines? For example, the suggested layout requires an area of 1"x0.5", and you have 3/4" square available for it. Or does this require manual intervention?

- Some of your example layouts have a lot of empty space. Is that due to user constraints or your process? Got to be the former.

- How do you envision board revs being handled? Will the user modify the schematic, or send instructions back to you for rebuild? If the latter, is the board layout deterministic? On a board spin I wouldn't want any more changes than are required!

Boy, I have a million more questions for you. This is cool. I look forward to you automating out some of the annoying parts of my job - the days and days of layout. I'm hoping you sell out to Altium so I can get this as a plugin - but I bet someone with much bigger pockets than I can afford will get you guys. Are you looking at yourselves as competing with the EDA companies or the EDM guys? Or both?

Good luck!
Most solar systems are grid-tie, in that they synchronize their output to your local electric grid, and feed any excess power into that grid. They do this by increasing their voltage output until all power generated by the panels is consumed, either by your house or by the attached grid.

Because of the way these systems are designed, they do not work well when the grid is not present. If grid power is down, and your solar system feeds power into your home electrical system, you will also be 'backfeeding' power into the grid. Since you likely cannot possibly generate enough power to satisfy your entire neighborhood's power usage, this will in effect overload your system. There is a second safety issue of feeding voltage into a grid system that the power workers are expecting to be dead. Electrical code requires these grid-tie systems to cease feeding power into the grid if the grid power is removed.

Most of these systems do this by just shutting down -- unlike backup generators with auto-transfer switches -- they usually do not have an automated method to disconnect the grid power while still powering your house.

If you were to provide some sort of disconnect, due to the nature of these systems, they would try to 'push' all available power into your house, because they're designed to force all available solar power into the electrical system. The grid can absorb this, but generally your home cannot.

They do have models that can function off-grid, and even models with attached batteries to handle surge loads and night-time operation, but these models are not as widely installed. Likely due to cost and/or owner education.

Are you sure about that? Society just accepts them and moves on?

There aren't lawsuits? There aren't recalls? There aren't redesigns? There aren't safety measures taken so deaths don't happen again? There aren't investigations? Fines aren't levied if they violated regulations? Regulations aren't passed in response? Everyone just rolls over and says, "This is just the price of washing clothes" like we are with autonomous cars?
NYT used to exist only in paper form which had no tracking abilities at all. They may benefit from this but I’m skeptical that they “need” it.
Well, as a business owner, I do have some idea of who "really pays" as you put it. When I charge my customers with Credit Card, I get charged a CC fee (around 2.9%). It's not that there is a free lunch anywhere: the merchants pay for it, as well as some consumers who pay interest on their balances, and some consumers who want special features from their CC.

But as a consumer myself, leaving debt part of the equation aside (since it is irrelevant to the transaction itself), I pay zero transaction fees with my CC, whereas I'd have to pay a significant fee with a cryptocurrency.

More annoying is that the cryptocurrency fee would be charged every time I make a payment. Looking at my CC statement, I can see I & wife made about 50 CC transactions last month, which would result in a significant "monthly fee" if we had used Bitcoin for example (to pick the most "widely adopted" cryptocurrency).

Like I mentioned above, cryptocurrency has very specific key positive aspects, but low transaction fees aren't one of them.

Get some experience flying a small plane. Like many here, I love to fly (destinations, seeing the world from above) but my lizard brain kept being nervous, particularly with turbulence. Then I flew over the Grapevine in from LA to the Central Valley in a Cessna in summer. It was choppy and there were drops, but they always recovered. I could feel that the air was there to catch us even though it let us drop a bit. Now turbulence is fun.

Try to think of it like a roller coaster: your reptile brain is freaking out but you know it’s not actually in danger.

> Land and not housing is a positional good

Yes, but the discussion about housing isn't "there is no affordable housing anywhere", but rather "there is no affordable housing near jobs and people have to commute very far", so I'm not sure there is a tonne of daylight between these two.

I feel you on the zoning issue, there is plenty of space that should be upzoned, but I don't think that this line is true: "A very substantial amount of inexpensive housing can be built where zoning currently disallows it."

Land costs are high, Permitting costs and fees are high, and construction costs themselves are very high atm, even if you're not putting in elevators or steel frame construction you're going to have very high costs that you can't recoup from low income renters.

Maybe if you introduced a land tax that made it expensive to have unimproved single family homes you could get somewhere, but as it is I don't think SF has the balance sheet to just spend its way out of this problem right now.

But even then, I think this is a problem that will take decades to resolve, since SF has gotten itself into a chicken & egg situation where everything is expensive because everything else is expensive.
I wish credit card fees would come down, they're ridiculously high and increase the price of doing business, which increases the prices you pay for items.
BUILD AN “AND” CULTURE and THRIVE – WOMEN IN TECH
Having people travel to hunt the meat they eat doesn't scale, though, at all. It's quite simply not possible to use it as a way to improve land use and reduce climate change. Suggestions like yours can be good, but they don't recognize the scale of the changes that are needed. It's the equivalent of trying to get people to buy hybrids to stop climate change - even if everyone could do it, it wouldn't make a dent in the problem.

Even given that hunting provides some kind of spiritual value (which I must admit I'm very skeptical of), it's a value only available to those who are by any reasonable standard quite wealthy (excepting rural people). It takes a lot of time, costs more, and is hard work that a lot of people aren't capable of. A marked increase in demand would make this even more of a problem.

Highly recommend Outback or SolarEdge inverters, but based on your AC load, you are going to need a sizable battery.
Tesla’s Powerwall isn’t the only solution (LG Chem has one as well), and as long as the battery is only ever charged from solar (not the utility, it’s an inverted setting), it’ll qualify for the 30% federal tax credit along with the rest of your rooftop solar install. Depending on your state and utility, there may be even more incentives available beyond the 30% federal tax credit.

>Your meritocracy is frequently indistinguishable from aristocracy.

I think there is a big leap from saying the crown Prince is most qualified to take the thrown and saying a meritocracy is frequently indistinguishable from aristocracy. I think Prince Charles is probably most qualified to take the thrown but I don't want the British government to go back to mostly inherited positions.

>Then why call it a meritocracy?

Google defines a meritocracy as "government or the holding of power by people selected on the basis of their ability." So since it is deciding on ability which is dependent on training and experience it is still a meritocracy.

>I find merit to be something that comes from within not from without.

But what is that thing within? It seems like you have ruled out experience and skills because both of those can be bought by wealthy parents. Even hard work is something that can be taught. It seems like you mean something closer to potiential (future ability) than merit (current ability). Also, what do you look for as evidence of merit?

Would a generator be able to supplant the grid? In effect have an auto-transfer but to the diesel/natural gas/propane generator? The generator would be idling except when power needs exceeded solar panels' capacity.

Might feel like a step backwards in terms of environmental impact, but presumable the fuel used would be minimal while the sun was shining or batteries not empty.

Another issue I just remembered.

Even if the system is designed disconnect the grid and operate in off-grid mode, without attached batteries, things will be very dicey. You will suffer constant brownouts and blackouts as clouds and weather obscure direct sunlight. I have a ~10kw system installed that only generates about 3kw when the sun is behind a cloud. Your lights will be constantly flickering and things powering up and down all day.

With properly designed system including the right inverter, panels, and batteries, you could go nearly completely off-grid. The cost would be several multiples of the cost of a normal grid-tie system, possibly even an order of magnitude more if you want to be able to have continuous power with all amenities(cooking, A/C, hot water, etc...) through a multi-day sun blocking event, such as a hurricane or blizzard.
I think the individual components were replaced, not the device itself.

> They buy expensive equipment and tags then come out here and work their asses off for a chance.

That's fine as a hobby, but it would create poverty and rapid depletion of wildlife if the majority of people were forced to depend on hunting and game meat for daily meals.

> If we can arrange for more people to harvest their own meat rather than accepting an industrial commodity.

This is a false dilemma. If we want to return to a nation of small farmers rather than a handful of industrial farms, all we need to do is increase property taxes on land ownership, as declining property tax rates are associated with increased rural inequality and a worsening gini coefficient for land ownership, where a greater fraction of land is owned by fewer people. Development of large numbers of intensive and efficient small farms can also be aided by marginal cost public irrigation infrastructure funded out of land tax revenues, which is how California developed its agricultural sector in the early 1900s using its public irrigation districts. Requiring households to devote large fraction of their labor towards traveling to hunting areas is not a realistic alternative.
Most other commentators here have hit the nail on the head, in summary:

- Backfeeding into the grid is unsafe

- Backup generators will throttle to not produce too much electricity for your home, so you can safely use a transfer switch

- Solar can't be throttled, excess power needs to be used, stored somewhere, or sent to the grid
This is something I struggled to understand when my system was installed.

With the normal grid-tie systems, all of the energy produced by the panels must be consumed. If you are producing more solar energy than you are consuming, while running on generator, the inverter will still attempt to force that energy into your home. The generator will take the brunt of it and will likely be damaged or destroyed.

They do have systems that can take inputs from Solar, Generator, Grid, and Battery and use the best available option. But they are significantly more expensive than the typical grid-tie systems.

Hey, whatever it takes for us to get to RISC on the desktop.
I don't agree: this is one chart where starting the Y axis at 0 would be more misleading, not less.

By way of analogy, consider a chart of somebody's body temperature in Fahrenheit: if that fluctuates +/- 5 degrees it's a cause of significant concern, +/- 10 degrees is a medical emergency. But all of those changes would look small and insignificant on a 0-based chart.

It's the same situation here. The ASP of a Mac is never going to be even close to 0, so the Y-axis should span only the range of realistic values so we can really see how significant the recent upswing was in context.
Newer inverters can throttle solar, as there are some markets where no export is permitted to the grid (the inverter optimizes the MPPT to effectively shut certain solar modules down).
