> Why levy high taxes on low mpg vehicles? Wouldn’t it make more sense to increase fuel taxes?

It makes sense to do both, because it's necessary to catch the average driver without pinching either end too hard.

It doesn't take much to convince the heaviest drivers to buy more efficient vehicles -- it may not even take anything, since the fuel savings is already thousands of dollars for them regardless of any taxes.

But they're still paying the fuel taxes even with the more efficient vehicle. Meanwhile the average driver would need a much higher fuel cost to convince them to buy the more efficient vehicle -- high enough that it would hammer the innocent heavy drivers who have already bought more efficient vehicles.

On the other hand, a combination of fuel tax and incentives for purchasing more efficient vehicles will convince the average driver to switch without putting too severe a burden on heavy drivers who have already done the right thing.

It's also generally not good to discourage productive usage. Better to get consumption from 100 gallons to 60 by going from 30MPG to 50 than by only being able to drive 1800 miles instead of 3000 and losing whatever value the extra 1200 miles of travel was worth.

And of course it would be the opposite if you tried to do it entirely through a fee on inefficient vehicles -- the amount required to convince the median driver on its own without a fuel tax would be too much burden for vehicles with light usage. Which is why you want a balance of both.
Fair enough. I was using a different definition, but arguing over definitions isn't a good use of time :)
Paying extra for a service like cc is just accepted in the US but not so common elsewhere. So even slight differences in fees will have merchants refusing to use the more expensive one even at the cost of bothering customers.
Yeah, that surprised me, too.

At one time in my life, I considered becoming a doctor, and had even started to take some of the required undergraduate coursework required to apply to medical school (organic chemistry, biology, etc.)

I started to talk to doctors about my choice, and nearly all of them advised me not to go into medicine and often went into a long rant about dealing with insurance companies, billing issues and being told how to practice medicine by people with only a high school diploma at an insurance company.

I might be a doctor today if it wasn't for them. I think it was for the best: I found electrical engineering in Silicon Valley to be interesting and highly remunerative.
What is stopping people from making meter sticks with 3000 lines, i.e. every third of a millimeter is marked?

(The point is, there is nothing any more "infinite" about the rational number 1/3 than 1/4, 1/5, 1/2 or what have you. It just can't be written in the arbitrary base 10 system, just like 1/5 can't be written in base 12)
iPad Pro Bend Test – Be Gentle with Apples New iPad
I try every year I try a few different Linux distros and each time I notice a tonne of UI and UX issues, and leave again (I mean, even the basic things like being able to resize windows is 95% of the time a pain on most distros I try. I'm sure there is a fix for it, but the point is, you shouldn't need to fix it, it should "just work").
In my mind Ubuntu is the closest, but still far far away.

I love Linux, and I use it almost every day (Debian), but only ever as GUIless servers, which it's amazing at.
Just hope one day a team with design and ease of use will make a distro that "normal" people can enjoy to use. (but you would need other apps that look and work great in it too, which I fear will be the harder issue to tackle)

I think you're exaggerating
For US readers, diesel cars are around 30% more economical than petrol cars, and most European countries charge less tax on diesel, meaning it is 5-20% cheaper at the pump (diesel costs more to make than petrol, but in Europe taxes make up ~60% of transport fuel costs).

I wonder if overall the economic benefits were worth it, based on what evidence is coming to light regarding the health effects of diesel vs petrol.

You missed my point. Of course it would be great to have a solution for every eventuality. However, the climate rapidly warming is the imminent danger. And it is the rate of change, not the final value, that is the most worrisome.
The actual blog post is much more informative: https://blog.verily.com/2018/11/update-on-our-smart-lens-pro...

Sounds like they couldn’t, with today’s technology, measure glucose levels to the accuracy required for medical devices. But will continue work on measuring other things with those lenses.

I don’t know why the negative tone of the article. Sounds like they tried something and demonstrated their specific solution didn’t work. Most research experiments generally don’t.

Pain returned to the dogs up to 18 months...

So the nerves must repair themselves over time which is great.
You're not listening, and that is part of the problem. We cannot have discussions, because the politics have polarized us. I'm not arguing that the earth isn't warming. I'm not arguing that humans aren't involved. I'm saying that there is a detrimental feedback loop between politics and science. This feedback loop means that we can't have reasonable discussions. Dismissing dissenting views as "climate change deniers" is a problem for science. And FWIW, though I'm a nobody, I have had private dinners with people who are somebodies (also, I respect that I'm an anonymous user on the internet which definitely helps my credibility - but I'll try anyway) - the people who have written IPCC reports and been in climate science research for decades. They share the opinions that I'm expressing, but dare not say them because they need grants; it's a delicate balance. The political feedback loop is a problem. It gets in the way of good science. Using predictive models can give us insight, but nature is pretty good at making fools of humans, and it's arrogant to believe that we can predict the future of something like the weather given the nature of the problem - we can't run controlled experiments, the data is super noisy and difficult to wrangle, and

There is no guarantee that the instance will come back. And it can be shut down in under 24 hours. Not that that's a problem compared to AWS or Azure.

>I suspect that only a minority of people in metric-using countries -- those with basic chemistry knowledge fresh in their mind -- know that "one milliliter of water occupies one cubic centimeter, weighs one gram, and requires one calorie of energy to heat up by one degree centigrade".

I wouldn’t be so certain about that. I’ve used that to conceptualize volumes and weights ever since I first learned that in school.
You've got it backwards. Counting to ten on your fingers predates the concept of our modern positional number system by hundreds of thousands of years. That's why base 10 was already the well-established natural choice when that system was invented.

Thinking that you could represent the quantity IIIIIIIIIIIIIIIIIIIII by the string "21" because it's 2 * 10 + 1, or similarly as "three fingers on left hand, three fingers on right hand" seems obvious to us now, but is actually pretty recent technology relative to the whole timescale of human development
I don't have a Mac, but I've used one for non-trivial amounts of time. I don't think it's significantly prettier than my Ubuntu + Gnome setup, but I'd agree there's a more consistent feel in the UI.

Asia has a Long way to go in regards to things like gay marriage. So does the western world. My point is there are many openly gay people in Singapore. While the law is against gay/anal sex (if I remember correctly anal sex is against the law too) and gay marriage is not allowed. It doesn’t mean people are forbidden to be gay in Singapore.

I’m against drugs outright. Weed included. The laws are strict in Asia. Not just singapore. However singapore has stated that if the overwhelming scientific conclusion is that weed is ok. Then they are open for allowing it in Singapore for Medical purposes. However since there is still a lot of conflicting science (despite there being positive benefits to weed) singapore wants it to remain banned. Alcohol consumption is only a real issue with foreigners in Singapore. It’s taxed so high here no one drinks other than foreigners.

> I suspect that only a minority of people in metric-using countries -- those with basic chemistry knowledge fresh in their mind -- know that

This is not the case. This part: "one milliliter of water occupies one cubic centimeter, weighs one gram" is known by most people, even kids in primary school. In other words everyone knows that a litre of water weighs one kilogram, and that there are 1000 litres in a square metre. I concede, though, that at least in Italy, which is the country where I was born and raised, most people wouldn't know the next part: "and requires one calorie of energy to heat up by one degree centigrade".

Even my newish bottom-of-the-range Mercedes e-class will do close to 60 mpg on the motorway. Compare that to the previous model from 3 years ago, which was giving around 50mpg, and from 10 years ago, giving under 40mpg.

The newer models feel lighter and more nimble. Almost as if they've got rid of a significant chunk of their unneeded, inefficient components from under the hood and replaced them with something radically different.

How is resizing windows on Linux far away from Mac or Windows? I think you're exaggerating
There is a divide between pure and applied math, one that arguable should be bridged, but the divide you talk about /within/ applied math seems artificial: Either you learn math properly, at least with regard to depth as opposed to breadth, or you shouldn't be working with it in the first place.

Within electrical engineering the design process is 1. pen/paper + math 2. simulation 3. building/testing. You learn quickly that jumping straight to 3, or even 2, is a /bad/ idea. This is because in order to isolate where the problem lies, you need to know what is expected. A similar process is used within any engineering discipline.

There is a such a thing as software engineering, where in the interest of safety the software system is documented completely. But in the vast majority of case, I hold the outre opinion that programming cannot in good conscience be considered engineering.

In conclusion: If you are working in engineering or applying math, you should learn math properly, and shouldn't treat it as a black box.
Countries cannot figure anything out if they are internally conflicted or poorly organized regardless of the peacefulness or wealth of their neighbors.

As an example look at Botswana. They are moderately well-off only because of low corruption and strong internal organization even though their neighbors are incredibly corrupt and have frequent political/military turmoil.

There's a known solution to sort out the SO2 emission, but it would cost a bit more.

I don't think real world problems are solved, we just exchange them for different ones.
You hope to go from: "there is no software for my platform" to "there is so much software for my platform it is hard to find a perfect fit" or "I'm so poor I can't afford to eat" to "I struggle to find an investment banker that I like to handle my investments".

Our current situation is sort of a consequence of:

Imagine a world where beasts of burden don't toil under the hot sun - where machines powered by refined oil products allow for the cultivation of crops, feeding millions.
Where machines relieve people of brutish work, freeing them for more satisfying and valuable pursuits.
Where durable and strong materials can be made cheaply from petroleum-based products that millions of households can enjoy.
Where hundreds of millions of people can be fed using more efficient agriculture that uses chemically produced fertilizer....

And so on and so forth...
>Our clinical work on the glucose-sensing lens demonstrated that there was insufficient consistency in our measurements of the correlation between tear glucose and blood glucose concentrations to support the requirements of a medical device. In part, this was associated with the challenges of obtaining reliable tear glucose readings in the complex on-eye environment. For example, we found that interference from biomolecules in tears resulted in challenges in obtaining accurate glucose readings from the small quantities of glucose in the tear film. In addition, our clinical studies have demonstrated challenges in achieving the steady state conditions necessary for reliable tear glucose readings.

Why wasn't this clinical work done prior to any work on "smart lenses"? This is like Theranos trying to build all this equipment to support fingerprick blood tests only to find out that venous blood is superior for a lot of things that you want to measure.

This Year’s ICO Funding Is Under Bear Attack, Falls by 48%
I really don’t know how this is going to work out for personal vehicles just given a lack of personal parking spaces. On any given night, the roads are filled with illegally parked cars (turning a 4 lane street into a 2 lane one), let alone parked in a space with access to a charger. It only works out for e-bikes because you carry the battery up to your flat for charging.

Most of the personal EVs I saw in Beijing were Teslas; because if you were rich enough to have a private parking space, you were looking for an Audi replacement, not an economy one.
Ask HN: How do you handle secret management?
All day I've been struggling with this: if I use a secret management system like Vault or Keywhiz or AWS KMS, I still have to store the credentials for that system in plaintext. So then I feel like I haven't accomplished anything whatsoever. To be honest I don't even understand the purpose of these systems.

Great book. Do get the most recent edition, because the recommend parts in the older ones are quite outdated.
I was born and raised in the US and I don't think I've ever met someone who has any sort of complex about the British Empire, or who would be any more insulted by "you should be ruled by the Queen" than "you should be ruled by the President of Uruguay" (or any other random country). The US was last part of the British Empire before most of our ancestors came to this country.

Honestly your comment, assuming it is meant to be taken seriously, strikes me as bizarre, and I suspect you're misinterpreting your American friends' reactions.
i was responding to this idea to amazon located in NYC because that's where the engineers/workers are at. If there's actually more in NJ, locating there would have meant those jobs would have just dropped in your lap.

Thank you for a neat answer.

I thought similarly to you on day zero of thinking about this question, asking if I could spend this time more effectively. I’ve decidedly answered no, and mostly because it seems subconscious and effective. I don’t tend to fight my “lizard brain”, particularly when it comes to non destructive behavior.

Tonight I walked home from a movie and found myself passively daydreaming about a conversation with my wife. I came home, she asked me about the movie, and I felt prepared to answer. It’s a trivial thing, but it felt remarkably purposeful in the moment.

Beijing already had more than a few EV taxis (BYD) in 2016, I heard Shenzhen was much more aggressive on this front. As far as charge times; these are taxi drivers who hangout a couple of hours at the airport for just one fare back, they probably queue up for chargers also.
There is a simple way to solve this problem.

A special startup can he inacted to solve this frequent problem.

We'll not use any special card or ID. Showing ID for a burger seems invasive and special loyality card, we can forget to carry it.

Blue accounts are loyal customers.

Green ones are tourist/one timers.

1. Use colored money concept.

2. If a customer sends money from their mobile wallet more than X times, their account is colored for this particular merchant.

If merchant has set a rule, if payment is > X times / Y dollars, then apply 50% discount for A duration/B payments.

3. Anyone not confirming with app, doesn't qualify for any discount.

Cash + app will also be supported.

Now simply adjust the prices to reach the demand you can keep up with.
They're already taking that into account.

This sounds wonderful for chronic pain. Reportedly, only pain neurons are affected. And for joints and other relatively isolated sites, effects can be targeted. So yes, your knee doesn't hurt, and you could injure it worse without the pain feedback. But you'd have ~normal pain sensation elsewhere.
