Solar watt-hours are not converted to BTUs at a rate > 1, however, the device effectively uses each watt-hour multiple times, as some of the energy is recovered after each cycle. Needless to say, if the goal were to produce energy, this would be impossible, but much like with heat pumps (which can exceed 100% efficiency by moving heat instead of converting electricity), the device is not producing energy from solar power. The baseline 100% efficiency they are comparing against is that of convertible the water to steam, i.e. the maximum efficiency of a solar desalinator that does not reuse any waste heat.

Not, the driving force is what people with disposable income are prepared to pay for. That's very different.
Generally not. Most people are willing to pay a little for it, and people who pay for their service are harder to justify cutting service to when times get tight.
Given that, at Google, he only went from a Network Engineer [2005] to SRE [2020], I don't think you can call that moving to defense contracting, especially as a SRE for the Ad Serving platform.
Yes, and it's a common thinking that's a quirk of the US; it's not a stretch in the US that an attack on one's employement is an attack on one's "physical security" or "well-being" because the US tied most people's health insurance to continued and stable employment.
I lived in Austin just before the advent of Lyft and Uber, and was thus stuck using the bus from time to time. I found the bus service in Austin to be unusually slow by US standards due to the abnormal number of wheelchair users.

Well, it is a story. Obviously the medium is designed to engage readers. This is not a scientific paper.
Strongly disagree.

> In my mind all the "internal activism" happening at Google and others is massively hypocritical. One cannot publicly criticize a company while enjoying cushy paychecks fueled by those very activities they despise.

Absolutely incorrect. Paychecks have nothing to do with whether you as a person find the company's policies palatable or not. Google employees provide a lot more value to Google than they are compensated for. They are well within their rights and should be encouraged to voice their honest opinions.

> 2. If they think Google is discriminatory towards LGBT employees and minorities, contributing to climate change etc., they are in for a big shock once they are really out of the Google and SV bubble.

So you would have them STFU, because the rest of the country sucks? This sounds completely backwards and doesn't make any sense to me.

comparing MSAs is more apples-to-apples than comparing manhattan to LA county, which is roughly what was being done. an MSA bounds the totality of the economic reach of a city, which more-or-less coincides with the commute boundaries.

LA (the city) is relatively dense (medium-high density) compared to its cursory reputation of being low density.

but public transit here is imperfect, to be sure. it's good if you live near a train line, and not so good if you have to depend only on buses. LA metro and LADOT are trying to change that, but it's a frustratingly slow process. micro-mobility options (e-scooters, e-bikes, car share, etc.) help.

Technically you could add or remove neucleons to change which isotope (or element) you've got, which would change the half-life. EG running a nuclear reactor changes the half-life of the fuel rod, by changing the materials in the fuel rod.

Planes also require you to strap in and put your tray tables up whenever the seat belt sign is on. There's generally not a meal service happening when the plane is tilting at 45 degrees.

One of the competitive advantages that train travel has over plane travel is that it is significantly more comfortable, and you can get up and walk around or have a coffee on your table whenever you'd like. Train travel would be less able to compete with plane travel if the experience was more akin to sitting in a roller coaster.

He has made enough money to retire. For engineers still looking for work, GOOGLE is the best place to work.
If you don't want to work at google, don't work there. Why do people keep blaming the company. This is not a dictatorship.
I currently work at Google, but I am a newbie, i.e less than 5 years at Google.

I frequently run in to people who are:
1) always been at Google and enjoyed the fruits of its rise or at another similar environment
2) never had to deal with frugality or lack of funding for anything
3) see themselves are superior to everyone else - in terms of how enlightened they are, how they know whats best for everyone
4) feel that they have an absolute say in anything Google does

These people do not know the realities of the world. Plain and simple. They had a good life and think that is it.

One thing they dont seem to realize is that almost everyone else has had to deal with growth challenges, lack of capital and access to resources. No one exists to only make the world better. Contrary to their disbelief, most people and organizations, including themselves and Google, have the first priority to survive, to grow, to flourish and to abide by all applicable laws. Once this is satisfied, they move on to grander things like charity, investing in the well being of others etc.

The very reason these people have the capability to leave their jobs for whatever reason is that they already took care of the first priority - to survive and thrive, courtesy Google.

Google is a business, and as a business it has the fiduciary duty to serve itself and its interests first.

If these people have any conscience that they claim to have, they need to stop pointing at Google, stop riding in their luxury SUVs, stop eating in insanely expensive restaurants, stop vacationing in luxury resorts, stop purchasing multi million dollar homes, and first go try to serve in the government to change the laws and society in which we all live and abide by.

Stop trying to tell a large corporation to stop doing business and make profits, go change the society in which it operates. Then we will talk.

Enough of the BS.

Thank you so much! "Masking" was the phrase I needed to find some potential solutions! I wasn't able to find much before, that points me in the correct direction. Thanks!
I'm confused by this argument.

Of course the steps from 'insane belief' and 'act perceived as immoral' can involve specific steps of reasoning which seem morally correct within the context of the insane belief. That's not the point, not a good justification for the act, and not something that we as a society should tolerate.

Some kind of incompetence, delusion, or misunderstanding is very often the cause of an immoral act.
A lot of people on hacker news get threatened by collective action. This is understandable, given the number of employers, wannabe employers and people with large portfolios who frequent this site.

This is kind of why I expected some people to make a big deal out of how this isn't a big deal. Tech unionisation is genuinely threatening to many here and this Google walkout stuff is a potential sign of things to come in this industry.
It’s extremely unlikely for a profitable company to need x$ in capital to drive x$ in sales. Cash flow is generally much faster than that.
Scientists and science-fiction has been dealing with/talking about climate crisis since the 50s/60s. A lot of the early stuff is tied in with some wrong (since disproven) Malthusian beliefs, but a since of post-fossil fuel-related climate change is an undercurrent through a lot of sci-fi. Even just looking at well known pop culture artifacts, climate crisis is a component of the films Logan's Run and Soylent Green in the 70s.

One of my favorite graphs on the subject remains xkcd's: https://xkcd.com/1732/

You can't read an exact "degree increase" around the 70s on that chart, but you can clearly see the seventies is in a notable slope/gradient as is everything post-world wars.
That argument cuts both ways. You don't know when the benefits of random will be there...

As soon as you do something that cares about order, state how it is derived. Sometimes, insertion order is right. Sometimes, not.

Don't get me wrong alists are nice. And order def matters to those. But it is part of their definition. And reinsertion changes the order in obvious ways. Not even clear what it does to just "dict".

Now, I will concede this is overblown. Life will easily go on.

> The only other options are to replace the battery or the device.

And battery replacement has been made to be as inconvenient as possible. 15 years ago, swapping the battery was a 15-second task that required no tools. Pull off the backing, pull out the battery, push in a new battery. Before Apple's response to bad press, it was $80 to have a battery swapped. Aftermarket kits were $30, so that is $50 on labor and markup. $50 to do what used to take 15 seconds by an untrained user.

This is a problem of Apple's making, by their design decisions.
> Google employees provide a lot more value to Google than they are compensated for.

how? can you justify what makes these people (you) so special? IN all honesty, they are probably overvalued in every sense.

>Absolutely incorrect. Paychecks have nothing to do with whether you as a person find the company's policies palatable or not

You are right because they already made their money and can afford to quit over whatever. Of course it has to do with money. Anyone who thinks otherwise is lying to themselves. If money did not matter, they would have not worked at Google, there are other ways to make the world a better place than add snow effect on photos.

I didn't say that people at large can't assess their emotions. When I said I have my doubts, what I meant is that I think that people are generally poor at it, which doesn't mean I don't think they're capable. There's a difference.

The rest of what I wrote wasn't really my full reasoning for that conclusion. I can only experience my own emotions, so I have to go with that. And I don't have any diagnosed psychiatric conditions, so I don't think it's that unfair to reflect on my emotional introspection. I never dictated anything other than that I have "doubts".

I don't have a specific reason why I think people aren't very good at assessing their emotions. It's a conclusion from an amalgam of my experiences with other people. People can certainly recognize if they are happy or sad, for instance, but I don't find they are very good at distinguishing between things like contentment and happiness. I've met lots of people who think that an absence of happiness is sadness, when in reality someone can be emotionally neutral.(the connotations around the word unhappy don't help) It's common for people to confuse depression for sadness. Personality and how someone can respond to emotion can mask their feelings, making them less obvious to both others and themselves.

>> If people had convinced themselves this was a ploy to sell more phones, then why on earth would they go back to Apple for another round

They believed their phones were obsolete, which it turns out they weren’t as it was in fact Apple who had slowed down the CPU to save power and made a decision not to inform users this was happening.

I believe the consequence of this was those users feeling they needed to upgrade sooner that what would have been. That is my subjective take on it.

Google Trends has shown that there is a spike in people searching for ‘iphone slow’ at the same time there is an iOS release.
https://www.reddit.com/r/dataisbeautiful/comments/agkgha/oc_...

While not causation, it is certainly correlated that people are perceiving a slow iphone when Apple release new software. Turns out the cause may have been Apple slowing down the phone in those updates.
I'm speaking more about the work moving forward. Search has fundamentally changed the way the world operates. How does China's government process look if backed by the talent of Google engineers for finding information?
Commute time is mostly a function of metro area population, not mode of transportation. Half of South Korea's population is in the Seoul metro (which has a huge population), so the average commute time is very high.

Compare NYC to LA: LA is driving dominant and has the longer commute time, despite a smaller population than NYC.
People react to stories, not data. Anecdotes bring global warming home in a way people can relate.

The irony, of course, is that it's a defining feature of some political cohorts to rejoice in getting people fired for things they've said online. I think it's clearly the case that an attempt on one's livelihood is a far more credible violation of "safety" than is, say, public speech on a topic with which you strongly disagree, but it's the latter that's described as such, while the former is often celebrated.
Maybe. 20 years ago Moore's Law was in effect. We've become accustomed to "it'll be so cheap in 20 years" because, from 1947 to 2010, transistors dropped in price by a factor of two every 2 years, while getting faster starting in 1975 due to Dennard scaling. Roughly, for ten thousand transistors or so, the prices (in inflation-adjusted US dollars) and response times varied very roughly as follows:

1950: $1'048'576 (1 μs)

1960: $32'768 (100 ns)

1970: $1024 (100 ns)

1980: $32 (20 ns)

1990: $1 (3 ns)

2000: $0.033 (0.5 ns)

2010: $0.001 (0.2 ns)

2020: $0.0005 (0.1 ns)

This is pretty inaccurate, but close enough to explain my point, which is that most of the humans have lived their entire lives and their parents' entire lives in this Moore's-Law regime, and it's coming to an end. But their cultural expectations, formed by three human generations of Moore's Law, have not yet adjusted; that will take another generation.

But who knows? Maybe some other similar exponential economic trend will come along and make AI cheap. But it isn't going to happen just by virtue of Moore's Law the way it would have in the 1980s or 1990s.
Is "Don't fire labor agitators" an extreme position? I'm pretty sure it's actually the law.

One could, perhaps, consider "Don't stumble blindly into improving the technology used for automated weapons" an extreme position in the US, but given that it's the country that brought us the atomic bomb, perhaps it is the correct extreme position to take.
Dorothy Parker's successor is perhaps Cintra Wilson, who was fired from the New York Times for this review [1] of the Manhattan J.C. Penny store.

It was never “get the look for less” so much as “get something vaguely shaped like the designer thing you want, but cut much more conservatively, made in all-petroleum materials, and with a too-similar wannabe logo that announces your inferiority to evil classmates as surely as if you were cursed to be followed around by a tuba section.”

Well yeah, obviously. I was talking about tickets in a broader sense, going by forms CHP 215 ("Notice to Appear", i.e. normal traffic tickets) and CHP 281 ("Notice to Correct Violation", i.e. "fix-it" tickets).

The solution to climate change is not to make energy producers like oil and gas companies go out of business. The way these companies became so successful was by providing something of value at a low cost. Do you really want to pay substantially more for heating/cool, gas, and almost every good?

Instead, the Tesla model is the way to go. Build products that are 10x better than their fossil fuel reliant competitors. This way, consumers benefit as well.

The government can impose a cost on carbon somehow, so the market is forced to consider the societal cost of carbon.
Also, it can incentivize clean energy by providing loans, lower taxes, etc to companies. It can increase R&D spending on clean energy.

Hiding behind "it's a business" isn't an argument acceptable to most people.

Sure "it's a business" but does that give it a green card to act how it pleases?

We're getting into the philosophy of what we want businesses to be in our society. More and more people are realizing that the inhumane structure a business operates in isn't acceptable to them, and would like to have a say in what they're doing.

This person left Google because Google was getting into the business of killing people - sure you might be comfortable with that. But your opinion isn't any more valid than someone who doesn't work in Google.

So please, stop telling people how to behave and act and protest. We're not putting in 100 hour weeks because someone before you had the audacity to go say the current system is inhumane.

You don't have to be that person, but you also don't have to be the person who stands in their way.
Did you read the post all the way through the concerns about supporting oil and gas industry, delaying of renewable development, comparisons with IBM and the Holocaust, drone warfare and military technologies?

And in a future where software-dependent devices have expiry dates, we can debate if worries about using them past their published expiration are warranted or are examples of social panic.
