You're right. Intuition isn't the same as data.

However I can see where the author is coming from as now I am engaged this is how I use Twitter too. Anecdotally it seems correct that people that get the best out of Twitter are those that interact publicly and productively with non-celebrity strangers.

One line seems to hit the nail on the head:

> On Twitter, you interact with people you don’t know,
> and the friendship doesn’t have to be mutual. This is a
> good thing, but can be scary at first.

This is what makes Twitter great but it depends on growing your confidence and interacting inside communities where this is a norm. It can be quite socially dangerous to mess this up: some communities have high walls and aggressive in-group tendencies, and some people do not yet have the social skill required for global online communities.

The other day I read this great quote by Nick Szabo on Usenet and I think it holds true for Twitter, too:

"Those who have never tried electronic communication
may not be aware of what a "social skill" really is.
One social skill that must be learned, is that other
people have points of view that are not only different,
but *threatening*, to your own. In turn, your opinions
may be threatening to others. There is nothing wrong
with this. Your beliefs need not be hidden behind a
facade, as happens with face-to-face conversation.
Not everybody in the world is a bosom buddy, but you
can still have a meaningful conversation with them.
The person who cannot do this lacks in social skills."

Twitter needs to connect like people to like people and slowly nurture positive, open conversation. But there are certain things you can't expect people to do with just a nice UX.

Perhaps they should be influencing with PR and education as well as UX.

> really good public transportation with buses and trains. I'm completely sure private cars or taxies would be discarted.

Wow. Talk about thinking everyone is exactly like you, and only your transportation needs need to be met.

What about the elderly? (Who can't walk the last mile from the bus.)

Or young children? What about a large family that needs a full car load of groceries - you're going to put that on a bus? And somehow carry it home?

Inevitably every single person who writes about public transportation is young and single, or at least no kids, and they think: No more cars, problem solved.

News flash: The entire world is not like you. Getting rid of cars is a complete non-starter for a HUGE segment of the population.
Well lets be clear unit testing temporarily slows immediate progress down while potentially increasing future productivity.

Sometimes its beneficial to get a feature out the door sooner so sometimes unit testing isn't best for the business needs even if it does slow down future progress.
This is pretty cool. I've had the urge to build something similar ever since reading Gwern's article about archiving[1]. My approach was going to either be an extension that ships URLs or just ship the history db wholesale to a webapp which does the archiving, which would allow for multiple machines.

One of small the altcoins - ReddCoin recently went from a market cap of ca. $600k to ca. $1m in two days, and everyone were inventing reasons for why. Except it was very simple: Someone had bought about $5k worth to pay his staff 1 week of salary in RDD (there was some tax advantage where he is to treating it as a "bonus" in something not recognised as a currency locally so they had an immediate advantage, and his company is crypto coin related).

Even for such a small coin, $5k was well below the typical daily trade volume. But here's the thing: He very rapidly bought off pretty much all the sell orders at 4 satoshi, and everyone started speculating what happened and prices shot through the roof, even though more coin than that enters the supply in no-time through mining still.

Point being that coins worth a typical daily trade volume can be enough to trigger large reactions in markets that are priced so extensively based on speculation about how other speculators will behave (take a look at the chat at various exchanges, and see the amount of chatter about which coin to buy into because they expect a pump or other forms of manipulation - very little of the chat seems to be related to non-speculative uses of the currencies).
The quote would better be placed around 'discovered' rather than 'ocean' considering it's all lab experiments and a pair of wet diamonds. Not to dismiss the hypothesis/theory, which seems pretty solid (no pun intended), but it's not like we discovered a new ocean like the Europeans discovered a new continent centuries ago.
That would be an ideal world, and I agree that safer languages definitely do make sense there, but the big question is how do we get there.

> That's the wrong place to attack the problem.

Then what do you think is the - currently practical - way to attack the problem?

I think there is a bit of misunderstanding I created in my original post; I'm not completely against security and hate buggy software as much as anyone, but only pointing out that we rely on insecurity for many good things and freedom we have today, and thus we should give more consideration to the implications of using more secure languages before they get to the point of becoming so popular that there is no turning back. They're just such a good fit to be used in trusted computing/DRM systems, and that's what scares me the most.
It's simple: Instead of just n, write "For a positive integer n". Instead of just k, write "For a key k".

It's simple.

Look, guys, 'n' just does not abbreviate 'integer', and 'k' does not abbreviate 'key'. Yes, yes, yes, I know; I know; and we should all know, that while too often people write, say, O(ln(n)) saying nothing about either 'n' or 'O', it's darned bad mathematical writing. If in some context n is a positive integer, then in that context it is just necessary to say so.

Read math from calculus to Halmos, Rudin, Dunford and Schwartz, Spivak, Lang, to Bourbaki, and will find that symbols are always defined; good authors just do not have undefined symbols hanging around. It's just not done.

Now you have learned something important. Sorry some people didn't know.
The central assumption of his whole argument:

> If you had to think what the transport systems would be on a sustainable modern city, I'm sure you would think that the solution would be a really good public transportation with buses and trains. I'm completely sure private cars or taxies would be discarted. (my emphasis)

is mere opinion. I like libraries and think the are great, but I still want my own books. There's no contradiction there.

Additionally, the title is inflammatory by calling people hypocrites instead of trying to understand why people use the services mentioned.
I appreciate the sentiment of the post, but cannot quite relate it to the Silicon Valley ethos. Isn't it the natural progression that we are seeing here?
Q: too much orange? A: Yes! I find it somewhat annoying as well; the standard identifier color was so close to plain white that I couldn't easily see the difference -- at least the orange is obvious.

Q: different colors for core symbols? A: Yes! I'm working on exactly that in the second style file (closure.lang in the repo) -- I've just added a screencap. The eventual goal is to distinguish between special forms, built-in macros, built-in functions, %-args, reserved, &, and all others. (I hope I'm not forgetting anything). Suggestions are welcome!
If you've never had Bart break on you or be delayed, then you weren't taking it enough.

SF public transportation is limited in its geographic coverage and the fact that it's not 24 hours. And that sucks. But San Francisco is also a much smaller city then Madrid, New York, Chicago, and the other places listed. Add a couple more million people to SF, South SF, and East Bay, and you can bet that public transportation will improve.
Slightly different, but I use a program called timesnapper [1] that takes a screen grab every second. It is so useful for figuring out exactly what I did a couple of weeks ago. The contents of your screen is a very useful data source.

You've alluded to "things which are optimal for humanity" and "our current problems". Could you elaborate?

What do you think is optimal for humanity?

Which current problems are more significant than planetary-level challenges like global warming and confinement of our specifies to a single planet?

These put the existence of our civilization at risk. I would really love to hear which other problems are more significant than those.

Which episode was that? I'm struggling to remember it.
Of course this article is a lot of hyperbole, and whether you agree or not depends on your worldview. But one bit I couldn't agree more. Uber and Lyft are NOT examples of the sharing economy. Just adding an element of technology to good old fashioned capitalism does not a sharing economy make.
I'm in the same boat. A lot of my friends love and use Twitter regularly, but I've never been able to get into it. I feel bad that I don't get it, because millions of people clearly find compelling use-cases for it, but my experience hasn't changed even after multiple attempts to figure out the missing piece.

Not everyone wants to ride in a bus. In fact, in my country people are stopping using buses, and doing some kind of car sharing, because it's much more convenient (available when you need it), they charge the same, and even though it's not much better space wise, a lot of people prefer riding with 3 others, than 20 others. This has been a growing trend, and I think it's inevitable that it will happen everywhere in the world.

Also, this is exactly the kind of service self-driving cars would offer in the future.
This. A thousand times.

My work gives me a (hybrid) car. Almost (~95%) every day I let it home and take the train to get to work.

But I have three kids and my wife is pregnant, so there's no way she could do almost anything without having a car.

I was web JS dev for a long time, didn't really touch any other platforms for 2 years (except for small scripts and automation, nothing big).

Then I started doing CocoaTouch for a project with a friend. I can't view the source, and the tools suck ass (xcode, obj-c) but compared to Javascript and especially the frameworks for web apps, it's wonderful!

The JS frameworks, all of them, make things a hundred times more complicated than they need to be. If web programming was like CocoaTouch, but with a dynamic language, it would be great. /rant

Im not sure you can take a single thing, the patent system, which also exists in many other countries, and then apply that as the reason for the US to be a bastion of innovation for 200 years.

How do you even know that the US has not been innovative despite the patent system. That if the patent system did not exist, it would have progressed even further than it has.
While you make a good point, the author isn't talking to everyone - instead, despite an inflammatory headline, he seems to be talking to many of the young tech crowd, whom he seems to actually resemble.

Bullshit.

Every example you give is just laziness.

Many many people in this world use public transport who are elderly, have kids, do the shopping.

Why can't the elderly walk to the bus? Have their legs fell off?

Perhaps people with certain disabilities might have issues that public transport can't solve, but they are not a large part of the population.

> Is $2.25 for a single ride expensive? Is $76 for the monthly cost of the BART and bus expensive? If you take into account what tech people earn is a ridicoulus price. So price is not a problem for tech people.

> Let's be serious, people are paying $12-25 for taking a Uber or Lyft when they could be paying just $2.25. Does it take longer? Yes. So much longer that you willing to pay 4-11x? I don't think so. People are wasting money.

Regardless of whether you believe public transit is the solution, the statement that people "are wasting money" is entirely subjective and dependent on what they perceive value to be. In fact, if tech people are indeed earning so much money (as is implied by the first sentence) then the higher they earn, the less of a "waste" the extra cost of private transportation would be be due to the factored in time-savings.
This! Graph theory should be taught very early to all children. It is as fundamental and important as simple algebra, and yields great insights without requiring tough computations.
This article is misguided. Using a taxi is good for the environment exactly because it is expensive. You use a taxi first of all because you don't have a car. You don't have a car because you either ride public transport or you walk/cycle.

Don't get mad at people who use taxis a few times per week for short distances. Get mad at people who clog highways with their polluting owned cars.

>Why can't the elderly walk to the bus? Have their legs fell off?

Please tone down a bit? They sure may have problem in walking maybe a mile or so to reach their destination. Buses aren't dropping them right in front of home.
Sorry, but that is BS. SF too small? Really.

Go and visit other countries in the world. Public transportation works pretty well also in smaller cities with a couple 100.000 people. Go look to Nuremberg, Germany with about 500.000 people. Go look to Jena, Germany with about 100.000 people. Cities in France or Spain or Estland or Lithuania. Look in Denmark or Sweden.

The reason in the US is simple: you love cars.
Sure Madrid has pretty good public transportation. But it also has an almost mysterious lack of bicycles. I have maybe seen a handful of them outside of parks. Not that I needed one myself, but it was just surprising to me.
> young and single, or at least no kids.

I'd say that was exactly who he was picturing...as people who use Uber & Lyft.

I think the point he is making isn't that cities can get rid of cars. It's that the majority of people who use these new services can _probably_ just use public transport.

Hypocrite isn't the word the author is after, but even if it were, effectively just insulting people you disagree with will not bring them around to your view point.

Uber and Lyft may well be 10 times the price public transport, but the services are otherwise barely comparable. It absolutely is worth $20 to me versus $2 to get where I'm going in a fast, comfortable, and private manner, in exactly the same way as I don't baulk at a $3 Starbucks, despite being able to brew a coffee myself for 1/20th that price.

Public transport is never going to win simply by being a cheaper option, you have to appeal to other motivators, such as sense of social responsibility.

As an aside, my "future city" vision of public transport would be publicly available, self-driving, electric "cars" recharged with renewable energy. Not mass-transit. I don't want to be forced into a shared space with strangers, if I can avoid it, thanks.
It's ability to be used to make better fake dollar bills would make it worth something, but the years in jail you might be subjected to if caught presumably drive the demand down.
yeah, not so many ppl are gonna use their patents.

Imo there will be :

* Oil stations (Esso, BP ,etc.). Electricity based car ARE the future. This is their chance to become a part of it.

Young children and the infirm can be served pretty well by specialized public transport for them. Eg. my small city has school buses for kids who live far from schools, and minibus service that will pick up and drop off the elderly from doorstep.

But of course public transport can't serve everybody's needs. But it can servve most people's needs, and if most people used it, it would be much better.

If your remaining need the car was commonly groceries, it's easy to imagine effective solutions for that. (Deliveries, cheap neigbourhood car rental or co-owning, bike trailer, uber, etc).

Ask HN: How can i help my dad?
My father has been working as a networking engineer for almost 40 years. He is exceptional at what he does. The problem is we live in a country, where things like perfection, attention to detail mean nothing. Also he is old, which is a big problem for most employers. 3 years ago he quit his job, because the owner of the company hadn't payed him for 7 months. My father didn't care for 5 months, continued doing his job, as if he was getting payed twice as much. After 7 months passed he brought the project to an end and the firm maid a substantial amount of money because of his work. He then resigned. My Dad didn't care if he wasn't getting payed, his work matters most to him and he proved it. It pains me to see him today (3 years later), still searching for jobs and going crazy, because he can't do what he loves the most. He started developing projects on his own, yet no one want to invest, because of the situation in our country(riots).
This has had quite the impact on our family in all the ways you can imagine.
I tried talking to him, yet he has grown distant and bitter. I'm loosing my father. He is in dire need of a job and i feel helpless.

TL;DR

Reactive programming is ill-defined and over-hyped, so let's talk about types and math instead (plus some not-very-subtle in-jokes about Microsoft).

An enumerator is basically a getter with the ability to fail and / or terminate. It might also return a promise rather than a value. An enumerable is a getter that returns an enumerator. We can express all this very cleanly in generic types. And if we take the category-theoretic dual of these types we get the observer and observable types.

So who needs reactive? ;-)
Think of it in terms of resource utilization. In the old model, there's tons cars that need to be parked somewhere within SF while completely unused. In the Uber/Lyft model, these cars usually enter the city while they're actively transporting people, then they go back to the suburbs when they need to be parked.

Sure, one could easily argue that parking spaces aren't the most pressing resource shortage, but the point is that these types of changes do create value by sharing resources. The same concepts can be applied to more pressing domains as well.

At the expense of sounding like a complete a-hole, I suggest you travel and see how other families/people live with public transport as their only transportation option. Don't get me wrong, I think Uber/Hailo/others are a great idea. Mix that with AVs and it will be a true disruptive technology.

Enrique Peñalosa, former Mayor of Bogota said that "An advanced city is not one where even the poor use cars, but rather one where even the rich use public transport", and imho he is completely spot on with the issue of transportation. The transportation problem in the US is a city/urban planning problem, and not one solved by building more roads and putting more cars on them.

Copyright laws apparently do not apply to google. They scrape the world but do not allow you to scrape them. The funny thing is that if a website would do what google does here they'd be penalized.

The google ideal is that the world provides content which it can then mete out at its discretion. For another nice example of google re-packaging content see google images.
Every example you give is just laziness.

"Laziness" is a term we use to describe situations where people are unwilling to put in the amount of work necessary to accomplish something that we could do if we were in their situation. The problem with that is that you really have to understand their situation properly first. If you're not a parent then describing someone who drives instead of taking the bus when they're out with their kids as "lazy" is just a show of ignorance. Even if you are a parent, you still don't really know what their kids are like.

Many people do use public transport, and that's great, but I'd hazard a guess that it's largely because they don't have an alternative option rather than because they think it's the best choice. Wrangling kids on buses is really, really hard work. Plus, if you have more than one, it's usually a lot more expensive than driving.

It's not "lazy" to use the most appropriate form of transport.
I don't think I've seen anyone suggest that Uber is cleaner compared to other forms of transport, just merely more convenient than normal taxi services.
I also don't think switching to pure public transportation is a viable solution in a lot of circumstances. Yes it can be very good when you're travelling between common destinations, but once your destination is more than 10 minutes walk from the train/bus station, the journey time quickly starts becoming burdensome. It's also nice to have a redundant system in place for the rare occasion that the public transport network fails (line upgrades, malfunction, bomb scares, etc).
