Do you think they'd really believe that it's worth just $5, or do you think they might have an ulterior motive?

Technically speaking, you're correct.

But would it not be linguistically simpler (and maybe less taxing for the reader) to use emphasis without resorting to percentages? The fact that 100% can be mapped to an unqualified boolean ("Yes, in favor, no buts.") and 40% cannot be doesn't mean that either are appropriate.

It's not elegant to parse sentence structure as categories to contrive percentage use as correct, even if it's technically sound. I understood the parent's sentence, but I had to read it several times because it just came across as a bit odd.

Honestly, when we start using category theory to analyze whether or not someone has appropriately quantified their stance on something, we've gone pretty far off the reservation.

I suppose my overall point here is that we shouldn't use percentages to quantify our opinions in place of emphasizing in a more linguistically elegant way. Maybe we'll have to agree to disagree?
I switched because most of my team uses brew, but I was happy with macports, it has a sane UI and I liked the way build options could be specified (i.e. "+python +png")

The only problem I had was that some stuff requiring compilation _outside_ of macports have builds that won't work naturally (e.g. phashion gem).

This is usually solveable and rare, but annoying.
OTOH I've seen similar issues with brew too (i.e. need to change openssl from system version to compiled version and recompile stuff)
Sadly, the reality is that most people seem to side with your perspective. And, like that, the great middle class boom that drove the golden age of the 20th century is over.

Recently, I've had the jarring realization that for Humans (and maybe nature, in general), the stable equilibrium point is inequality. And, like the cab drivers, a lot of us have to 'suck it up' and realize that the 20th century (and perhaps the whole post-enlightenment period) is not coming back. So, better to brace ourselves, tighten up our finances, and ready our families for the 'low-growth' future.
regular basic inspection/maintenance (in Australia it's once a day from memory) of taxis mean a customer is much less likely to get stuck somewhere because their taxi had a mechanical failure.

Taxis drive a LOT more km/miles than regular cars - more driving, and particularly more city driving === more wear and tear on the cars systems.

Yet again it seems to me that the fandom around uber in the USA is because your taxi regulations are just stupid. I've never heard of "the card machine was broken so I was forced to pay cash".
When they made this change in the recent Chrome update, at first I couldn't believe it.

> be able to install in there as an unprivileged user is utterly ridiculous.

this. I'm using homebrew and installing every package as my own user is a security risk. One security mistake in a package can interfere with my main user account's files / other packages / etc.

Other package managers (apt, yum, macports, etc.) install each package as separate users (e.g. Mysql as user 'mysql') to prevent bad packages from 'leaking'.
I don't consider installing Xcode to be an unreasonable thing to do to - consider that 70+% of the people who buy a mac have no need for the compilers or system libraries. So it doesn't seem unreasonable to me - I mean, my debian box doesn't come with any of the devtools installed - and its a couple gigs of software to install.
they work side by side, you can just call "python27" vs "python34" and the same happens for related tools (pip, pep8 etc).

I don't think that's the case?

My worst drivers are usually people who just don't have experience driving. They drive slow, they don't know the city, or they get confused other ways. Or they're just timid and don't know how to take a right on red. I'd much prefer a cabbie who's in an Uber.

But I'm also someone who judiciously gives people lower stars. The rating system works for us! People just need to be willing to give 1-stars and file reports.
Do you understand what an analogy is?

You said people are leaving existing jobs to drive for uber.

My response is that people make bad decisions all the time. That doesn't make the decision any less bad.

Also, based on most research, driving for Uber is generally nowhere near as well paying as they imply it is, when all costs are taken into account.

Overall quality of life is improving but if you look at the shrinking success of middle class, I believe the reason is income inequality. The economy is health when money is changing hands and more and more money is in fact locked up and not providing any economic activity. This is way the so-called economic recovery hasn't really been felt on the ground. We have a literal handful of people with more wealth the entire rest of the country. And the real sad part, is that wealth is just a number in a computer somewhere. It doesn't contribute much. Those who have that wealth can't spend enough of it to make a significant economic difference.

That inequality could be taxed and provide, for example, infrastructure which is a benefit itself but also provide jobs and generate a cascade of economic activity, like consumer spending, that simply isn't happening now.

I assume you're getting your data from here[1].

I'd counter by asking which modern society does not have homeless citizens. Particularly, which countries that rank more highly than the US in the Quality of Life or Human Development Indices?

The other challenge I have is that homeless in America enjoy a quality of life patently superior to that present in nearly every class virtually everywhere else in the world. Sure, homeless in the US are not as well off as the middle class in Switzerland, but they're certainly better off than the median individual in India, Peru, Pakistan, Syria or Zambia (to name a few from what would be a long and saddening list). The resources consumed by, and available to, homeless citizens of the US make them look like citizens of Elysium in comparison to those nations.

To flesh out one example - the bottom 5% of Americans are about as wealthy as the top 5% of Indians.[2]

>Truck driver is the most common profession in most states.

You'll find that "software engineer" is becoming the most common profession in many states where truck driver previously was. [0] If truck drivers become software engineers, that's a big quality of life upgrade. You'll also find that prior to the computer revolution, "secretary" was the most common job, because it took a lot of people to coordinate normal business. Computers optimized that away and everything went fine.

Capitalism doesn't work if we fret over the losing side in every competitive accomplishment. It's a competitive world out there, and some hustle is required.

>Self-driving trucks will make their jobs obsolete overnight.

It won't happen overnight. I personally don't think automated driving will be available to the masses half as quickly as most HNers seem to, but that's beside the point.

Adoption will be cautious and gradual. No trucking company wants to risk their cargo or their reputation on tech that hasn't been proven ridiculously reliable. Small portions of fleets will be converted at first, and probably tested for at least a year before they're expanded out. Different companies will adopt at different times. Specialized trucks will have different requirements and may not be immediately available.

There are regulatory issues that haven't even been broached as the technology is not fully realized yet -- I believe it will probably take a decade or more after the tech hits mass market before autonomous driving is a smooth legal process in all 50 states. Full adoption won't be able to occur until autonomous driving is universally legal.

The point is that the whole industry is not just going to wake up one morning and find themselves replaced.

>What will happen to retail? What will happen to wholesale shortly after?

Nothing, because trucking companies won't disrupt service to their clients in the process of converting to an autonomous fleet. It'd ruin their business if they allowed technical upgrades to disrupt their schedules.

>That truck drivers keep their jobs, or that they are gradually able to transition into new ones, is not just necessary not to feel bad about them, but to keep the whole economy running.

They are able to gradually transition as the move to autonomous will be gradual. Nonetheless, companies do go belly up with little warning sometimes. It doesn't seem to stop the economy.

Let me float this idea. A lot of truckers are owner-operators, which means they own their own cab and hook up someone else's cargo. Clients pay per job. Perhaps the fleet will become autonomous as owner-operators upgrade their cabs, at which point they'll make a lot more money because they can just dispatch their cab to get hooked up to some cargo and then be free to engage in other productive activities. Just one possibility that would be impeded by a government program to subsidize non-automated trucking.

There is no need to be alarmist here. The transition will be gradual enough, and people will innovate as necessary to survive, as they have for centuries.

James: An Open-Source HTTP Proxy and Monitor Tool (alternative to Charles)
Low socioeconomic mobility is a problem because the potential for any individual to contribute to the good of society is at best loosely correlated with their previous socioeconomic status. If people who could have been top-notch scientists, engineers, civil servants and entrepreneurs were prevented from doing so because they couldn't move up the ladder (and inversely, rich rent-seekers couldn't move down), society is deprived of their contributions and is worse off.

P.S.: The rapid change in up and down votes is probably caused more by your confusion of socioeconomic mobility and equality (you seem to be using the two interchangeably) than anything else.
Yea, investments are risky. They're supposed to be risky to make up for the potential rewards.

Sometimes you can pay to remove risk, in the form of insurance, which can be expensive. But if you aren't paying to remove the downside, someone else is.
> JSON is just javascript,

Today json is not really tied to javascript that much, I deal with it all the time in python that doesn't include or interact with javascript. JSON is just dictionaries and lists (and strings and numbers and nulls) this is pretty easy to express in dynamically typed languages and not that hard in statically typed languages if you give up on a bit of (static) typing. I don't see any reason why it should be limited to a subset of javascript, there are some good reasons for not changing it all though.

Income inequality is a misleading metric. I would argue that equality has vastly increased over the years.

The rich don't really live much better lives than the middle class.

Rich or poor we all have roofs over our heads, we all have access to relatively affordable methods of travel to get anywhere in the world in a day, we all use the same IPhones, watch the same movies and drink the same Cokes.

The things that the rich have access to aren't really that much better when you compare it to the old days when you contrast Kings living in Castles to the 90 percent who are just worrying about their next meal.

Where did I conflate socioeconomic mobility and income equality? I didn't intend to do that.

More to your point - I respond by asking whether or not the socioeconomic standing of a scientist matters for the societal impact of their work.

I don't see an easy conclusion here. The scientists driving innovation in industry are generally paid very well (this is relative, but we can probably agree they are paid higher than a median salary). The scientists driving innovation in academia are not, as a rule, paid as well as their counterparts in industry, but that doesn't stop them from contributing valuable research to their fields.

So how do we conclude that socioeconomic stance matters for a scientist's research impact, if they have grants or corporate sponsorship?

To reiterate my point - if reduced socioeconomic mobility can't be demonstrated to be a net loss for society, why does it matter if income inequality causes it or not, and how does it demonstrate income inequality as a net loss for society?

> Thus Japanese had settled on having few syllable sounds _before_ there was any way to write them down, so their syllables _can't_ have been limited by their script (at least initially).

You might be underestimating just how huge an influence Chinese has had on Japanese:

https://en.wikipedia.org/wiki/Sino-Xenic_pronunciations#Ling...

Japanese (as well as Korean and Vietnamese) imported Chinese vocabulary en masse, including a gloss of Chinese translation. That made Japanese much more homophonic since the tones got dropped in the process.

Just compare the kunyomi (native) and onyomi (Chinese-derived) readings for some Kanji and you'll see that the onyomi readings are usually single syllables.

"For example, Sino-Japanese words account for about 35% of the words in entertainment magazines (where borrowings from English are common), over half the words in newspapers and 60% of the words in science magazines."

That said, I don't really agree with GP's contention that using Kanji makes Japanese have a simple sound system. Chinese has a somewhere richer sound system even though it invented the characters (especially if you count tones), and Spanish and Italian have very simple sound systems even though they're written with alphabets.

It's interesting to note that quite often in these discussions the idea that no other key exists comes up. In the 1990s, keyboard manufacturers started adding "multimedia" and "Internet" keys to keyboards, including keys whose sole and explicit functions were to move backwards and forwards in a WWW browser's navigation history (or in GUI applications in general).

These keys have obviously, even in this everything-in-the-WWW-browser age, still not embedded themselves thoroughly in the public consciousness. There are clearly sizeable classes of people who don't yet regard them as the norm; and people who still first think of keys other than those explicitly engraved for the purpose as the ones to use for it, or do not even know that such keys exist.

To those who are about to miss the point: Yes, your current keyboard doesn't have these keys. You didn't regard them as the norm when you bought a keyboard/computer. They haven't become so established that you don't regard systems without them as deficient, as you very probably would regard systems without (say) a "Super"/"Windows"/"Apple"/"Command" key. This, even in a world where doing many if not most things in a WWW browser is seen as the norm.
