NickM··on Why Is Uranus the Only Planet Without Interesting Features on It?
The longer answer it is too cold to make the same cool cloud patterns in the visual spectrum Jupiter and Saturn have.

That's not what the articles says at all.

NickM··on Ethereum Plans to Cut Its Energy Consumption by 99 Percent
Growth in the economy is not necessarily predicated on growth in consumption of natural resources. Those two things tend to be correlated in modern society, but they're not inextricably linked; we don't necessarily have to give up on the idea of economic growth in order to preserve the environment.
NickM··on Ethereum Plans to Cut Its Energy Consumption by 99 Percent
"other people having different values than you" makes it sound like the value of ETH is purely a matter of personal opinion. It is, however, possible to fundamentally misprice an asset. I think OP is arguing that the ultimate real-world utility of ETH is not accurately reflected by its price.
NickM··on Norway's electric cars zip to new record: almost a third of all sales
I'm sure of the US govt increased the federal tax credit for EVs from $7.5k to $40-60k, you'd see similar adoption in the US too.

I get your point, but to be fair, the numbers in your comparison are a bit off, since a $40-60k tax credit would make many electric cars effectively free. That would be a much bigger incentive than what Norway has.

NickM··on A new generation of environmentalists is learning to love atomic power
These seem like very reasonable questions to me. Is this comment just getting downvoted because pro-nuclear HNers don’t like the opinions being expressed, or can someone legitimately justify the negative comment score I’m currently seeing?
NickM··on Breakthrough ultrasound treatment to reverse dementia moves to human trials
There was a great Radiolab episode about the lower-frequency stuff. IIRC, the hypothesis there is that you can stimulate certain types of brainwaves that tend to run on similar frequencies, so that seems like it's probably working via a separate mechanism from the proposed effects of the ultrasound treatment, since ultrasound is way too high-frequency to correspond to any known brainwave frequencies. Perhaps both treatments could be complementary, though, assuming they both pan out.
NickM··on Ask HN: How did you decide where to live?
Smaller, less "glamorous" cities are often the best option for remote workers in my opinion; there are a lot of cities out there in places like e.g. Ohio or Western NY that are looked down on as "boring", but which actually have a lot of culture and fun things to do, and are still large enough to have a decent amount of nice restaurants/amenities/etc... And at the same time, they also have very low cost of living and avoid a lot of the overcrowding problems you see in bigger, trendier urban areas.

Personally, I live in Rochester, NY, and I absolutely love it. There are definitely some neighborhoods that I avoid, but there are also extremely nice areas in the city with beautiful yet affordable housing and lots to do. There are all kinds of fun events, concerts, and festivals going on all year; lots of nice restaurants, bars, and coffee shops; an assortment of beautiful parks; the list goes on. The community of friends I've met here is also much more tight knit than anything I've encountered in bigger, busier cities.

I think a lot of people tend to gravitate toward extremes: I see a lot of answers in this thread pointing to very large cities, or super-rural areas out in nature, or far-away international metropolises. There's definitely something to be said for picking a middle ground, though - I feel like I get to have my cake and eat it too, and if I want to occasionally go to a Michelin star restaurant or climb a mountain, I can always do that on vacation (which, of course, is easy to fit in the budget too, given the amount of money I save by living here).

NickM··on How “One-Plus-Five” Is Shaping American Cities
Well yeah, nowadays contractors can charge through the nose when hardly anyone even has the necessary skills to maintain existing slate roofs anymore, much less install new ones. It didn't always used to be like that, though. The material cost is more, of course, but not nearly 7X more.
NickM··on How “One-Plus-Five” Is Shaping American Cities
Yes, absolutely. I live in a city with a ton of old freestanding houses that were built around 1900, and they're incredibly sturdy. You can see this all throughout the construction:

The frames are built from really thick wooden beams that can take a beating. I had a large tree fall on my house earlier this year, and the trunk bounced/slid off, doing only superficial damage to the roof and siding; I talked to multiple contractors and insurance people who said a newer house built using modern construction standards would've been flattened, or at least suffered serious structural damage.

Things like windows are built to last too. The original wooden sash cord designs are still functioning 100+ years after they were built, with the exception of a couple windows that needed the cords replaced, but that's relatively cheap and easy. I expect the same windows will continue to work another 100 years as long as they're cared for and maintained.

This isn't about "the democratization of luxury", as another commenter suggested. Cheap construction costs more in the long term. This is about a cultural shift toward favoring short-term over long-term thinking. Long-lasting wood sash cord windows would not be expensive to build in this day and age, and they could be quite energy efficient too with modern glass and weather stripping, but people don't think or care about the long term the way they used to, and so they'd would rather settle for cheap, shiny vinyl windows that yellow and crack and fall apart in a matter of decades.

NickM··on How “One-Plus-Five” Is Shaping American Cities
This article seems to be putting on some strong rose-colored glasses. It appeals to the idea that people in the past all lived in beautiful, long-lasting buildings. The reality is that the long-lasting buildings are the only ones that still exist.

Well sure, but at least some houses used to be beautiful and long-lasting; nowadays, even large, expensive mansions are typically built in a cheap, slapdash manner, using techniques and materials that are not nearly as long-lasting or durable as the ones that would've been used to build a nice house a century ago.

For a really obvious example, just look at roofing materials; a good slate roof can last over a century with minimal maintenance, but nobody builds houses with slate roofs anymore. Instead, even high-end homes use asphalt shingles that last 20-30 years tops.

NickM··on Can We Grow More Food on Less Land?
Let's try to break this problem down to first principles:

- Humans need food to live because it provides energy and nutrients.

- From a fundamental standpoint of physics and available materials, nutrients are relatively easy to get; as far as I know, most vitamins and minerals are pretty cheap to either come by naturally or manufacture, and you don't need that much of any of them to keep a person healthy, so let's assume food energy is the real limiting factor here.

- The energy in most food comes from photosynthesis (either directly, in the case of eating plants, or indirectly, in the case of feeding plants to animals for growing meat).

- Photosynthesis is an extremely inefficient way to turn solar radiation into chemical energy. Only about 3 to 6 percent of incoming solar energy is used by plants to create biomass, and not all of that biomass necessarily equates to calories we can digest and absorb.

So, while this isn't a particularly appetizing future to imagine living in, I don't know of any fundamental reason why artificially producing edible calories via solar electricity and chemical processes couldn't vastly exceed the efficiency of natural-grown food. It might be tricky getting to the point where fake food like this is healthy and tastes good...but if it saves the world from starving and stops civilization from collapsing then hey, it's not a bad fallback plan.

Besides being a big jump in efficiency, this type of tech could also enable the use of non-arable land for food production, since presumably you could set up the necessary manufacturing facilities anywhere you want.

NickM··on Tesla's giant battery saved $40M during its first year, report says
The raw materials are certainly valuable enough to be worth recycling, assuming it's not terribly hard to separate them back out from each other.

But suppose we never figure out a good way to recycle these batteries, and we just have to throw them all in a landfill and keep making new ones. Is that actually so terrible? There's nothing toxic in a typical li-ion battery, so basically we just have inert materials that were taken from the ground being put back in the ground. Mining for nickel/cobalt/lithium is not great for the environment, but the effect is pretty localized, so a "disposable battery future" is probably still highly preferable over the fossil fuel status quo where the entire planet is fucked.

NickM··on A million-dollar drug
Maybe caving in and lowering the revenue would encourage future customers for other expensive treatments to boycott high prices and hold off for price drops. Refusing to negotiate and forgoing revenue now could be the rational strategy in the long term.
NickM··on GitLab Made $10.5M in Revenue with Every Employee Working from Home
Sure, but what I can't fathom is why they would pay more to hire a dev in SF or NY when they could easily hire a better dev for the same price from somewhere else. Allowing remote work is a big benefit from the employee perspective, so I can see why they could get away with paying less than certain other employers, especially if they're hiring people from areas with less competition from other high-paying employers...but why would they then throw those savings away by hiring someone from an expensive city and paying them a premium when the whole company is remote anyway?

They claim they want a "geographically diverse team", but without saying what benefit that brings them, that doesn't really explain anything.

NickM··on Cadbury ‘pushing orangutans towards extinction by wrecking habitat for palm oil’
Individual action is unlikely to be effective in this case. For every person that cares enough and is aware enough to boycott these products, there are a thousand other people who either don't know, don't care, or can't afford to take the time and effort to change their behavior over something like this.

If you want to make an impact, look toward political solutions; raise awareness among your friends and family, write to your representatives, send a letter to your local newspaper, etc. etc. The only reason companies are overexploiting these resources is because it's profitable; a small tax or tariff could tip the scales in a much bigger way than your own individual consumer habits ever will.

NickM··on Do the Rich Capture All the Gains from Economic Growth?
The whole thing he is explaining is just regression to the mean.

The author directly addresses this further down in the article. Regression to the mean is a possible explanation of the numbers he cites, but it doesn't refute the main point he's making, which is that some numbers suggest poor people capture more of the gains from economic growth than is widely thought.

NickM··on Microplastics found in 90 percent of table salt
True, but there are potentially much larger economic and social costs incurred when people remain oblivious of something that is harmful. Playing it safe is likely worth the cost, even if we pay for a lot of false positives along the way.
NickM··on Blockchain isn't about democracy and decentralisation – it's about greed
Nope, printed money is fine too. I used to live in Ithaca, NY, which had a fairly successful printed currency called the "Ithaca Hour": https://en.wikipedia.org/wiki/Ithaca_Hours
NickM··on Blockchain isn't about democracy and decentralisation – it's about greed
it's the first time in hundreds of years when an individual can print money and not be called a criminal...thanks to blockchain there's nothing stopping you to create a coin for your group, your neighbourhood or your town

Local currencies have been created and used in many places all over the world for a long time, without needing anything like crypto. Nobody is being called a criminal over this, it's quite common.

NickM··on Jason Fung explains why intermittent fasting diets work
The calories in/out model is technically true, it's just not very useful. It's like saying "there's no secret to how a jet plane works, you just need to have enough lift to counter gravity, it's basic physics." Well, sure, but there are a lot of other variables to consider that will dictate how hard/expensive it is to build a working aircraft.

Playing with other variables besides calories, like the specific foods you pick and the timing of meals, can produce dramatic, measurable health changes and make a huge difference in how hungry you will feel at different times of day.

EDIT: I just saw the other reply someone wrote that used a rocket analogy instead of a jet plane analogy, funny how we both independently came up with such a similar response.

NickM··on Why Do Computers Use So Much Energy?
Phones are much less powerful than PCs, but they feel comparably fast because most software developers waste exactly as much performance as they can get away with. The phone app developers are forced to write better, faster code than the PC app developers, just as PC app developers ten years ago were forced to write better code than PC app developers are today.
NickM··on Denmark to ban petrol and diesel car sales by 2030
I think all the bastardized carbon accounting, market based solutions are on average quite bad.

I'm curious, do you think the whole idea of a market-based solution is bad, or do you just think that actual real-world implementations have been lacking so far?

I mean, it seems to me that if you tax emissions strongly and uniformly enough, then at some point it has to have an impact. I think existing schemes have just been pretty weak.

I agree that carbon taxes can potentially hit poor and middle class folks unfairly hard, but this can easily be solved via carbon dividend type schemes.

NickM··on Waymo self-driving car crashed when driver fell asleep and triggered manual mode
How do you feel about cruise control? Or automatic transmissions?

I like semi-autonomous systems because they still take some of the cognitive load off of driving. Paying attention is still easier than paying attention plus constantly having to adjust speed/steering/etc.

NickM··on The End: I can not finish Limit Theory
I can’t say, but keep in mind that there are plenty of examples of indie games that used a custom engine and went on to be highly successful. It could be that those games would have been just as successful with an off-the-shelf engine, but perhaps there is something to be said for the DIY approach.
NickM··on Ask HN: What was the best decision you made in your career?
I think you're misinterpreting what he's saying (which might be my fault for expecting the quote to make sense outside the context of the talk). The quote is referring to the fact that we frown on people making money from running charitable organizations that help people, but making money from running a for-profit business that helps nobody is considered fine and admirable.
NickM··on Moon Is Stepping Stone, Not Alternative to Mars, NASA Chief Says
A thin atmosphere is still very different from no atmosphere. If you have access to CO2 you can break it apart to get breathable oxygen, or use it as in ingredient to make methane to fuel a return trip. If you have no atmosphere to draw on at all, then it seems like it's a lot harder to become fully self-sustaining.

There is also something to be said for sending humans to a place where humans have never been able to go before. To many people, that's an end goal in and of itself.

NickM··on Ask HN: What was the best decision you made in your career?
I mostly agree with you, but I wouldn't entirely blame nonprofits. There's a lot of public pressure on nonprofits to reduce costs as much as possible because everyone is obsessed with "overhead". This TED talk explains the problems with this situation really well:

https://www.ted.com/talks/dan_pallotta_the_way_we_think_abou...

Choice quote: "so in the for-profit sector, the more value you produce the more money you can make, but we don't like non-profits to use money to incentive people to produce more in social service. We have a visceral reaction to the idea that anyone would make much money helping other people; interesting that we don't have a visceral reaction to the notion that people would make a lot of money not helping other people."

NickM··on Tesla Faces U.S. Criminal Probe Over Musk Statements
Your answer is correct too, but the question originally asked was "what would he have gained from destroying the shorts? I understand that shorts are effectively a bet that the stock will go down but do they actually damage the company in any way?" The answer is yes, short sellers do damage the company for a variety of reasons, some reasons relating directly to stuff like stock price, and other reasons being more indirect like the one I cited.

I saw that other answers had already explained how shorts lower the stock price, but nobody had pointed out the other ways in which they "damage the company", as the original post put it.

NickM··on Tesla Faces U.S. Criminal Probe Over Musk Statements
I don't know why I'm getting downvoted. The parent post asked why short sellers harm companies, and I gave a legitimate answer, and that answer is also exactly one of the reasons Musk cited for wanting to take Tesla private.

Maybe folks are skeptical about the fraudulent NHTSA complaints? If so, here's a source: https://electrek.co/2016/06/13/tesla-fale-complaints-suspens...

NickM··on Tesla Faces U.S. Criminal Probe Over Musk Statements
If you short a stock, you profit when that company does poorly; since Tesla is one of the most shorted stocks out there, we have many people trying to spread FUD via blog posts/tweets/etc in hopes that they can drive the stock price down. (Or in some cases even going to extremes like fraudulently submitting reports to the NHTSA claiming design flaws and problems with Tesla cars.) This has the side effect of damaging public perception of Tesla.
