They most certainly did. As expensive as that software is, it’s very little when amortized over the rides. It eliminates the overhead of finding a location and transmitting the info, and delivers higher value in that it gives real time data about where the car is, and lets you pay more conveniently.

Also: while the drivers have physically taken over maintenance, Uber can’t push the economic cost on to them, because they have to pay enough that drivers want to continue to work even given those costs. If anything, maintenance is cheaper when handled by a big org.

To the extent they realize a savings, it’s because they’re using the spare hours of existing vehicles and don’t have to take on all the dead ours they’d have from owning the cars not because they’re getting maintenance free in any meaningful sense.
I wouldn't call it a stigma. I'd say there are issues with doing it appropriately. Adults have jobs, children, etc. They do not have the same "freedoms" a child has. While a child is forced to learn because of school+family, they have "free time" that is used to reinforce that. With adults, "free time" for reinforcement is harder to allocate.
The pilots are dead, how do you propose fixing their failures? Or do you mean we should also focus the standard checklists and procedures? Are we not doing that also? I think the article sufficiently tried to cover those as well.
A little randomness is fun and enjoyable. Not to mention, it can throw off those ad targeting algorithms a bit by injecting a little disinformation into the mix.

One of my favorite (now, sadly defunct) links was http://random.yahoo.com/bin/ryl to give you a random link from the Yahoo! directory.
There's less clutter and interference in the written word. It's just a dialogue between two people. One of them talks from his life experiences, like a grandpa, the other one listens, ask questions, wonders, like a little kid who doesn't know anything about life.

What does a video add to this dialogue? Only clutter, in my opinion. If it's a word for word reading of the original, then that definitely adds some value, but then you'd call that audio and not video. So I assume by video you mean moving images, and sound and tone and interpretation and change of pace and interruptions and "I'm waiting to be inspired moments" from you and "Here's a video with dramatic music on top of it. Are you amazed?" from the video producer. Adding splash doesn't mean the producer knows what he's talking about. Often times it's just a way of hiding the lack of understanding.

For a comparison, a good website doesn't need anything besides black text on a white background. A website that doesn't have anything to say will have to compensate with flashy tricks and will make you unaware of the fact that it has nothing of value to deliver.
You get the distinct sense that you’re walking through a computer rendering rather than a real place. Aesthetic is prioritized over function everywhere you go.

In the Shops and Restaurants at Hudson Yards, escalators are not positioned to allow a seamless flow up and down the levels of the mall, but rather, to make the complex photogenic; often requiring you to search at each level for the next escalator down in order to exit.

We seem to have generally begun to err in this direction. We are surrounded by visuals 24/7 via TV, magazines, internet, etc in a way that wasn't the case when I was a small child and didn't exist at all when, say, my dad was a child.

I think this is a consequence of that. Our focus is much more on looks than on other aspects of the design experience or life generally.

I don't know what the solution is. I keep toying with the idea that I want to, for example, blog about clothes or home related things without jumping on the bandwagon of filling it with appealing photos. It seems like a non-starter though.

But we have women undergoing cosmetic surgery because we are so focused on these photo shopped images of women who are already statistical outliers in some way and whose look was developed by a combination of a professional makeup artist, professional wardrobe person and professional hair stylist. Then they taped up her breasts and put 30 bobby pins in the jacket so it would fall a certain way. Then a professional photographer took 300 pictures, only one or two of which are going to be used in the publication.

Let me reiterate: After all that, they are photo shopped to boot to achieve some completely unrealistic notion of beauty or perfection or whatever.

We think that's what real people are supposed to look like. The magazines that do this literally try to sell us on the idea that they are in the business of telling us how we are supposed to look, never mind that no one can actually look like that in real life, not even the professional models who were used in the shoot.

We do the same thing with housing, home decor, etc ad nauseum.

And it is going bizarre places in a manner that is negatively impacting how we conceptualize and create real spaces, clothes to wear and so on. Then we wonder why so much stuff out there is dreck.

I also live in NY and the opinion expressed in the article is a common one. The NYT tore it apart in an article (with particularly well-executed visual effects)[1].

The fact that a lot of people visit it is just a factor of Manhattan being an ever-expanding series of tourist traps. Along with the 9/11 Memorial Shopping Mall the island is looking more and more like Mall of America. Madame Tussaud's is popular, yet it is generally reviled among residents and frequent visitors along with the knock-off Broadway characters at Times Square that will kick your teeth in if you take a selfie with them without paying (yet they remain a popular attraction). New Yorkers will tolerate crappiness if it is at least convenient and will tolerate opulence if it is at least nice to look at. Hudson Yards is neither.

If you have a dire case of FOMO then it might seem like a nice addition but it's just a shinier version of the malls that you see at every highway exit in the country. The city's venerable institutions have not changed and still quietly offer arts and music and there was certainly no shortage of world-class dining before Hudson Yards went up. Unless you've been pining for Thomas Keller's latest take on a thousand-dollar bowl of bong water[2], who needs it?

That's sometimes how Japan does it as well. A few years back I had to take a day trip from Tokyo to Sapporo to install a piece of hardware.

At the Tokyo Narita airport, this Japanese guy in jeans and a leisure jacket standing next to me suddenly pulled out a badge and said (in English), "Police." That was unusual, but he went away after asking me a few questions about where I was going.

When I arrived at Sapporo, I collected my bag and was walking to the bus when this Japanese guy in jeans and a leisure jacket walked over to me, pulled out a badge, and said (in English), "Police." He too asked me a few questions and went away.

When I returned to the airport a few hours later to fly back to Tokyo, this young woman in an Oakland Raiders jacket came over to where I was buying a drink from a vending machine and asked where I was from. I told her that I was actually from northern California and the Raiders were my home team. After chatting with her for a couple minutes, I went to find my gate, and as I was walking this Japanese guy in jeans and a leisure jacket stepped over to me and pulled out a badge and said (in English), "Police."

And yes, it happened again one more time when I got back to Narita.

So the MO was obviously, "Find all visually identifiable persons of non-Japanese ethnicity and conduct a brief interview. And dress casually!"

It was slightly annoying, but they were all reasonably polite. I told the fourth cop that I had been stopped four times that day, and asked why they were doing it, and he told me there was some sort of Asian economic summit happening. ¯\_(ツ)_/¯
I'm not the parent but if I had to guess, I'd say it's the way new media seems to erode our ability to concentrate for long periods of time. YouTube et al provide us with endless stimulation such that we never allow ourselves to get bored anymore. Then, if we're doing something we may find tedious and difficult (say, grinding problems from a math textbook) then we can't handle the lack of stimulation and get restless as a consequence.

Taking a break from all of that stimulation is a good way to quiet our minds and relearn how to focus.

You can make the argument that this is the difference between being an adult and someone who is still a child.

That being said, it is not a black and white line, depending on the context many adults can act like children and many children can act like adults.

> “Indeed, in Apple’s latest release of its mobile Operating System, iOS 9, a number of the issues we have discussed have been addressed.”

This is a strange line to find 90% into the article. It seems like a lead in rather than a late acknowledgement. iOS struggled to find its way back to usability after rejecting “skeuomorphic design” in favor of flat design (see the drop in emphasis on metaphors), but it’s doing better now.

> Discoverability

This does continue to be an issue. However, the subtle bars that indicate the availability of the swipe up from the bottom and swipe down from the top right are helping.

> Undo

This is a huge design flaw. I finally enabled shake-to-undo because I’ve started doing more work on iOS and needed undo, but I feel foolish shaking my phone. Photoshop introduced the history palette years ago and that’s a fantastic approach to undo/redo. Now the feature is common on desktop apps. iOS badly needs a “time machine” control as a universal access to undo/redo. The rewind/fast forward 2-finger gesture introduced in the Paper by 53 was a nice solution, but not widely implemented. An icon would be better.

> Feedback

The most satisfying feedback on iOS is the click vibration when the flashlight or camera app snap open after a long press on the lock screen.
In Spain, the immigrants that I talked to said it took them about 3 years to become proficient, and the first year was horrendous and hard as they could not communicate the essentials of daily life (going to stores, navigating public transit).
That's likely a large party of why the NSA prioritized gaining access to their data through various programs, some of which have been exposed over the years. And when you're talking about nation states, even minor Hail Mary efforts have access to extensive resources sufficient to represent an entirely new sort of threat model to those companies. I doubt anyone at Google was worried about the risk of the NSA digging up their private fiber cables in the middle of nowhere with a backhoe to tap their internal communications prior to revelations about the program.
If you haven't measured the difference between different allocators for your C++ programs you are probably using the wrong one. The system allocator can be 2-5x slower than an allocator that more closely matches your workload.

€4.50/GB is the maximum what EU operators are allowed to charge each other for roaming data transit right now, and what an external operator like Twilio would probably have to pay them. Of course in each country you will find operators who offer better deals on their own networks - but Twilio can't reasonably build out their own worldwide mobile network.

Despite this, I can see this service being popular among companies who are willing to pay a bit more per GB to avoid negotiating with operators and getting SIM cards all over the world.
I absolutely agree about lectures, _when they try to teach a textbook_.

If the lecturer discusses a topic on the premise that their audience has already read <whatever>, it's a much better experience for all involved, in my experience.
I got really confused when I first saw this and though it was something for consumers not IoT devices (Sorry twilio team for the application for access shrug).

I really wish someone would nail this for consumer phones. I'm coming up on a year away from home in various countries and the constant sim swapping is beginning to get annoying.

I actually bought a dual sim phone so that I can keep my Australian sim card in for 2FA security sms messages (etc).

Before someone suggests it, Google Fi is US only, unless you want to arrange for a reshipper (and even then, I'm not sure if it works).
Read up on the extensive reporting on both accidents. They never reached that conclusion because it was absolutely unexpected, as a result of Boeing’s stealth changes to the aircraft.

There was an article recently where they put very experienced pilots in a simulator under the same conditions and they all failed.

The entire article reads as someone specifically searching for something to criticize, and some of these are a real stretch. The sloppy cladding and bricks is surely not ideal, but is it really a big deal at all? It's hardly noticeable unless you are specifically looking for things to nitpick. The "damaged wheel" picture in particular is literally just paint chipping on a piece of machinery that hardly anyone will actually see. Who cares?

As for the design criticisms, it's clear this person doesn't know much about actual design principles, despite criticizing the designers for it.

1) The escalators are almost certainly purposefully designed like this. This is common in many places, and I especially have seen this design used in many malls. Along with the fact that it guides people to product display areas, it also prevents dangerous traffic jams on the landings between escalators (it takes longer to get on an escalator than it does to get off, so in high traffic situations, you can end up with a lot of bunching at the top of an escalator, which can mean dangerous situations like this [1]).

2) Stairs are a common bottleneck since it takes longer to go up/down stairs than it does to walk on a level walkway. To prevent bottlenecking, the stairs should be wider than the walkways they connect to. This is the same principle you see when tollbooth plazas have more lanes than the highways they connect to.

3) The complaint about the gap in the railings again seems like an incredible nitpick. The author claims it is a 6 inch gap, but based on the photo, unless this person has massive hands, it looks more like a 3-4 inch gap, and I think it's a real stretch to call that "dangerous".

This is about things we actually use, and their bad usability when your senses decline with age.

If you really used that clunky phone, you'd appreciate how at hand it is, and how fast it is to use compared to a cell phone, specially when you desk calls are short.
Really cool. Hope Microsoft keeps the momentum going with releasing new features on Github.
That's a good question, and I'm honestly not sure. I think highly parallel, general purpose and customizable computers have uses outside the mainstream. So they would make great ray tracing video cards and platforms for physics simulations for science research, stuff like that.

I think most problems in computer science today can be traced to the original sin of choosing Von Neumann architecture and imperative programming over reprogrammable hardware and functional programming. That's why we think of things like machine learning as rather difficult problems, even though they are just simple algorithms that are compute-bound.

Basically my complaint is that this stuff has progressed in spite of our choices, not because of them. The proprietary and closed-source hardware, drivers and programming paradigms we have to deal with today have set us back at least 20 years. Probably more like 40 years if you include some of the shenanigans that happened between IBM, Intel, Microsoft and Apple in the 80s and 90s. They solved personal computer problems wonderfully, but inadvertently hindered the progress of computer science in general.

I don't have an answer for why the market tends to reject the stuff I talk about. I just know that mathematically it's very first-principles stuff that I really hoped would have caught on by now. To me it feels like these ideas keep getting sabotaged for economic and political reasons rather than scientific ones.

Edit: I forgot to mention that FPGAs solve this problem by providing generic reprogrammable hardware whose use can't be monopolized the way that single-purpose hardware is. Something like open source FPGAs (that don't burn up when they're programmed wrong) would allow us to explore many more problem spaces in computer science than we can currently.

In isolation it my be great that this is better than a rail yard, but it's important to note that Hudson Yards was financed in part by a diversion of a year's worth of funding from low-income housing elsewhere in New York: https://www.citylab.com/equity/2019/04/hudson-yards-financin... ... and in that context, it's notable that it's not a set of constructions that's built to last.

Hmmm, your response is amazing. I was just sort of pondering a far out idea. But the amount of time and energy you put into your response is awesome. So cool that you thought about my dumb idea that much. Not trolling just thinking about far out ideas. I like your response a lot.
The person replying to you agrees and was just adding an interesting and relevant quote to the discussion. Not every post on the internet is an argument.
The problem is that only Boeing is left in the US. Lockheed, Douglas, General Dynamics are all out of manufacturing civil airplanes. It's the lack of free market (the decision between Boeing and Airbus is most often a political one), not the lack of regulation that led to this. Boeing is too big to fail now. Regulators are always stupid, but free market is smart.
Having a bit of difficulty following this, so I'll break down my understanding of CRDTs and see if someone can help me out.

A CRDT can be thought of as an algebraic structure, consisting of data type D, and a join function. So for all a, b, c in D, it's:

Associative:

join(a, join(b, c)) == join(join(a, b), c)

Commutative:

join(a, b) == join(b, a)

Idempotent:

join(a, a) == a

Partially ordered:

if join(a, b) == b then a <= b
a <= a == true
if (a < b) and (b > a) then a == b
if (a <= b) and (b <= c) then (a <= c)

So given all of that, I am not sure why the example in the article holds. I assume it's a consequence of the partial ordering, but I don't know what the partial ordering is. What's the join operation and what's the data type?

Lots of states have value-based registration fees.
>I guess what matters is what data holders do with it.

If only that was what mattered. What also matters is what they're going to do with it in the future, along with what the people they're going to give it to will do with it, and what the people who steal it will do with it. (Not to mention what they're doing with it right now but not telling you).

My personal theory is that because injuries tend to heal eventually and also because they tend to physically hurt, people have a psychological tendency to underestimate the infinite future and also to underestimate anything that doesn't immediately result in physical pain.
Interesting thought. I wonder if LLVM IR has a semaphore primitive? In which case it could map to the HSEM in STM32 or an instruction sequence for other machines. IR seems like the natural place to put this kind of functionality, especially since you need to guard either the HSEM or the equivalent sequence from being disrupted by over-eager code motion. (Which historically was a problem with gcc -- on the AVR architecture, at least, gcc liked to move SEI and CLI to the top of the function instead of leaving them in place, because there was no way to specify the idea that the interrupt mask bit was an absolute fence to code motion. Not sure if that is still true.)
There have been countless cases for me personally where Googles tracking is creepy. Like Google Map recommendations, YouTube videos I should watch, misleading ads that send the user to malware bases on interest Google has about them etc, as well as exposure of unauthenticated Google+ APIs that allowed access to sensitive data to name a few.

I think saying nothing bad has happened is disingenuous. As soon as Google gets similar exposure as FB right now, internal whistleblowers might come forward also with more stories.

Also, couple of years ago Google was thoroughly compromised by at least one foreign government, ever wonder how much data was stolen?
Maybe first build a capable editor, with plugins, etc (xi-editor is not that yet) and worry about "collaborative editing" later?

And even for that, I think simply "taking turns" (where users share an editor session, can chat with each other, and can switch on sequentially who gets to actively edit) is enough for 99% of cases, and is not more difficult than mere single-person editing (since there are no conflicts).

Do children learn languages quicker?

Obviously they learn their native language quick because of full immersion plus playing and talking is pretty much the only thing they have to do. For other languages, if they spend say 3 hours a week learning another language they'd probably be at the same level as an adult spending the same amount of time. And things like curiosity, feeling of relevancy etc. are going to be a bigger factor in speed of learning I reckon.

In case I wasn't clear, the kind of 3D rendering I'm describing doesn't use graphics cards. It's all on the CPU.

As for ideas to make a faster CPU, sure, knock yourself out. But there's no question that computers today are much closer to 10,000x faster after 25 years of development on actual, real-world code being run to earn billions of dollars. Your approximately 10x faster claim after 25 year is just wrong, at least with the software systems I'm familiar with.
