When I heard Uber was getting into Transit I imagined something more disruptive than just aggregation of different transportation types.

Consider: Public bus systems are constrained to fixed schedules and stops for obvious reasons.
Neither apply in a Mobile App.

Uber could sign up drivers who own mini-vans or large buses, and dynamically generate "bus routes" using on key waypoints, and both ongoing and forecasted demand (based on historical data).

As a consumer, the experience is still
1) Pick a destination

2) Go to the spot where Uber asks you to go (Which already happens in places like Airports, or if you use Uber Pool which asks you to move a little closer to the route to decrease driving time

3) Get in the uber

4) Get off at a spot when the app/driver tells you which isn't exactly at your destination but close

All for a much much lower price

Meanwhile, as a driver, the experience is:
1) Follow the Uber app's navigation that tells you where your next 'Stop' is.
2) Drive around in a circle that changes throughout the day.

It's a hard problem to solve and get perfect but it would actually justify improving an existing public service.
Not to defend the app in question, but certain public transport organisations publish incorrect data.
One example of this is the RATP (Paris public transport) - they refuse to publish live feeds: the data they publish is a basically their "best effort" static timetable.
Out of curiosity, what was the application?
How do you solve B and C without coupling the shape of the components tree to the state of the state tree?
Commercial oat milk tends to have far more protein than almond milk too. Almond milk has almost none. Soy has the most.

(Although homemade almond milk would seem to have a lot more than boxed. 1.5 cups of almonds to 3 cups water is 7g protein per cup. Close to soy milk. Whereas commercial almond milk has more like 1g per serving)
Not really. I can buy the kit from a reseller or even OTC by cash and send it back without providing a return address.

Apart from that, I shouldn't need to register on their website to access my results. There could be unique, randomly generated URL on a scratch card in the kit, where the results will be put as soon as they are done with sequencing.
You made not need redux! Found lot's of projects where they plug redux an turns the project a completly mess. (connected components everywhere), actions to manage local component ui state..
I can decide that for myself. I don't need an 'authority' to tell me, regardless of who the author is.

Do you think that without the warning, a beginner would deep into the article, and 50 minutes in, he/she would be like 'heeeey, wait a minute! This is not for me! Why didn't he tell me?'

If not, then such a disclaimer is meaningless.

…wow. I don't know what to say; this is pretty egregious. This seems like it came out-of-the-blue; why was Dominyk forced out? Because he made this pull request?
What? I'm not sure how that connects to my comment. I'm saying that some games install to "My Documents" to avoid requiring administrator privilege for users who might not have that privilege.
Don't know much about pricing and IP since I've only been doing open source/hobby projects... But I've heard this complain a lot. Maybe it has something to do with that when Ada is used it's often for very high stake projects, and they need very expensive insurance?

> I know I'd certainly feel safer riding on pretty much any transportation written in Ada over C or C++.

Indeed.
Do we really want Google to editorialize in this way?
On mobile platforms, app don't use polling loops for that sort of stuff, precisely so that power usage could be optimized. Time for something similar for the web?

Is it? I would expect the variance in the sustainability to be quite high, with the most sustainable (pasture fed) dairy farms being much better than the average almond milk producer. That’s just an intuition though.

Also assuming we’re talking per gram of protein and fat here. Cup for cup almond milk might be more sustainable but there’s far more nutrition in a cup of cow milk.

But maybe it should be!

Why do we allow these exclusions in the contracts?

I'm sure we have regulation on what can and cannot be part of the insurance terms.
It is. The entire region is a giant landslide hazard, which makes it extremely time-consuming to build things, including the ends of bridges.
Exactly. Didnt say dupe or put a date (which would imply dupe) on purpose. I dont need to tell you it's better to read the news a week+ late if it's from a news maker[0]... those baked in assumptions are so much easier to identify. Looking back on the North Korea threads is going to be interesting.

How anti-theft tags work – magnetostriction [video]
Fair point, but you know very well that, for true illustration, you'd have to expand out the meaning of the words "countable", "regular", "Hausdorff", "space" and "metrizable". And I bet you could. I get the sense you're being obstinate for a point.
I knew, or at least knew of, some of the vest guys as fathers of people I grew up with. As in any group it’s a mixed bag, but I feel pretty confident that none of them were missing their true calling in pushing forward the boundaries of our understanding of hidden markov models or getting speech recognition to work. We’ve used those kind of resources to free up people to, I don’t know sell whole life insurance policies or something. I’m sure there’s a sense it which it is efficient, like I said I’m not a centrally planned economy guy, but there does seem to be something off about it.

I mean there are computational cancer models that need to be written and optimized.
Convolution is a linear operator (with a certain special structure). So convolutions are represented just like any matrix-vector multiplication. Given the special structure of the convolution operator, it can be represented in a sparse manner, and what's more, the actual computation can also be implemented in an efficient manner, compared to a naive matrix-vector multiplication.

TL;DR: It can be represented easily using Einstein notation. Einstein notation just does not capture the sparsity properties we like; it represents the transformation properties quite nicely.

TL;DR - the tags are small pieces of alloy, mostly iron. Hitting them with a magnetic field causes the alloy to change shape very slightly. Doing this with a high frequency magnetic field causes the strip to change shape rapidly and to 'ring' after the external field disappears. When the magnetic field is monitored using a second coil, this ringing can be seen. The tags are turned on and off by magnetizing/demagnetizing a second magnetic strip which functions as a magnetic bias, changing how much the first strip changes shape.
> our senses are fundamentally rooted in the physics of atoms, and there just aren't that many fundamentally different things that atoms can do. They can absorb and emit photons, they can stick together and be pried apart, they can emit alpha and beta particles, and they can fuse and fission. That's about it. And with those fundamental building blocks there is only so much you can do.

Our traditional physical senses:

- Sight. Based on interacting with photons.

- Sound. This is based on atoms physically colliding with each other. However, we process it using a complex apparatus that essentially performs a Fourier transform on the raw air-pressure data, extracting the frequencies of the wave pattern that reaches our ears on the assumption that a wave pattern is what we will get.

- Touch. This is based on atoms colliding with each other. It is set up more for the detection of large-scale structural characteristics. (e.g. hard / soft / liquid)

- Smell. This is based on atoms colliding with each other. It is totally unlike touch in that the sense of smell processes molecules based on their molecular shape -- the specific way in which they interact with dedicated sensors -- rather than on their physical characteristics. At this level, you're interacting with a molecule more than with a substance.

- Taste. From a physics perspective, this is basically just the same thing as smell. From a biology perspective, it's pretty different.

I don't see this as good evidence that the set of possible senses is meaningfully limited by a simplistic view of how atoms can physically interact with other atoms.

We have many other senses that are less obviously based in simple physical interactions, like the sense of time.

Some people have had magnets implanted, leveraging their existing sense of touch into a sense of magnetic fields. This is something humans don't ordinarily have, and is actually not allowed for by your list of the capabilities of atoms -- you forgot that atoms can hold an electric charge -- but is analogous to some other animals' ability to sense electric fields.

I'm curious how you think "emitting an alpha particle" differs from "being pried apart" or "fissioning".
I think this is because you are using both state and props to manage the values of fields. I generally tend to use only props, with an onChange handler passed in from the parent component. This way, I can always have an up to date mapping of field names to values in the parent component, while simplifying state management in the child.
I would argue that for practitioners it is the same planet. But I agree that they are not the same thing.
I’ve found Kikkoman Pearl is the best in coffee.
That's a plot point that is used a lot, and it's not really a sitcom thing. More of a hero's journey get-him-Jack-Reacherized sort of event.

I had it happen once in a move: At 23, all my possessions got squeezed into 6 packages (5 of which were media mail), a bookbag, and a checked luggage. Everything else got thrown out or given away. I'd been living in a furnished room. At the new location, the only thing I needed to replace was a computer monitor.
There has been a general flocking back into the cities in the last ±20 years.

I don't know about Bend but all other cities you mentioned are desirable urban hotspots with (relatively) plenty of attractive jobs.

I find it very easy to imagine the supply of people interested in moving to all of them outstrips supply by so much as to practically be indistinguishable from unlimited.

There really are a lot of people around and there are as many in not more decaying/depopulating areas to compensate for the Austins and Berlins of the world.
> utopia in which software would plug together via function/procedure/method calls

Hmm...The Fine Article actually argues that procedure calls are too low level for software interconnection, and that is the major reason why we aren't there. (and they haven't really improved in the last quarter century since the article was written).

Like the analogy in the title of using assembly language to build large-scale software systems.

But you're right that the alternatives are also often quite messy; talking to other systems is generally not considered a first class concern, but rather something you cobble together, somehow, out of parts that aren't necessarily fit for purpose.

And I think there are actually good reasons for using web and file APIs (composability, simple GET/PUT semantics) that are independent of other aspects (using HTTP, OS mediation...) but come together in one package.

My Objective-Smalltalk[1] is an attempt to build a language where these concerns are first class and separated out, for example with Polymorphic Identifiers[2] to generalise resource/variable access, Constraint Connectors[3] and Object Filters to generalise dataflow and Higher Order Messaging[4] to generalise messaging/procedure calls.

One interesting outcome is that once you see these more general concepts in a "pure" setting, you can bring them back to other languages, for examples "Stores"[5]. Not quite as nice as with proper language support, but still very useful.

Today you can insure against systemic risk through re-insursnce in other countries.. this should be a benefit from globalization, right?

So why we keep allowing insurance companies to make these exclusions?

If there is systemic risks to the entire planet, then an insurance company should just go bankrupt.. I mean the survival of a company isn't very important if we talking about the apocalypse :)
The disclaimer might serve an important purpose: reduce the amount of questions the author receives via email/Twitter. The disclaimer is obviously not written for you who can decide for yourself, but for people who are quick to write questions instead of reading the damn thing.

How do I know? Because I have disclaimers here and there that are obvious for most people and still help to reduce the support burden.
I minored in history, maybe I didn’t pay enough attention to it, but I can’t think of a period where we’ve been more free than we are now. Not even 10 years ago. We live in a time where you can frankly do anything you want if you’re born in the western world. If you want to become a blacksmith who specialises in creating fantasy weapons, you can do that. If you want to disconnect and go live a self-sustainable life in the Swedish forest, you can do that and unlike the hippies of the 60ies you won’t even have to starve if you suck at it. And so on.

I think it’s completely possible to live a full life and never realise you had the option to be free though, and, I think it’s fair to blame the way we’ve constructed our society in the wake of new public management. We’ve essentially build a system where every human being is viewed as a Hunan resource. It starts in the daycare institution where the social workers have checklists for normal child development. It picks up in the school system where academic achievement is measured from the first classes and children have to know their path from the 6th grade to make sure they take the specific classes which allow them to advance to the next institution. The once you’re on the job market you’re evaluated on productivity and finally when you retire it’s about keeping you in good health so you cost less. All to make sure people are as efficient to the system as possible.

Social media and the massive surveillance state that we’ve build by sharing everything plays right into this. We self-censor and pretend, and everything we share on the “free” tech-platforms is kept and used against us. Which I completely agree is very worrisome.

The thing is though, 1984 was right. If anything the current level of surveillance and manufactured information is way worse than Orwell predicted, and yet, you can still go make fantasy swords in the Swedish forests if you wanted to.

I just don’t share the authors negative outlook. Maybe I’m naive, but I really don’t think that we’ll turn the west into China. I think things like the European GDPR is a show of this. We don’t want companies or governments to misuse our data, and we’ll punish them if they do. It’s happening slowly, but that’s how a democracy operates, because you have to compromise. It’s happening though, and it’s happening because people wanted it.

I also fully expect the younger generation to rebel more than we did. You see it already on climate issues, with children refusing to go to school if they won’t have a future anyway. I suspect they won’t want to keep our surveillance state or our HR centric view on society either.
Seems like it's precisely because of that PR. Maybe Mike saw it as a mutiny. But I'm guessing that since he never explained himself in that PR, he's not going to do it at all. It's not like he's unaware of it.
> My son Atlas is just over nine months old [...] One thing that’s been troubling me, is that he probably wont have [privacy] in his lifetime.

> I write systems that predict the moods in real-time of nearly a million people who are communicating on the internet (HNProfile.com & RedditProfile.com).

Moral bankruptcy at its finest. No one is forcing you to write systems that do this. You can easily make top-tier salaries at companies that value the privacy of their customers.
This sounds a lot like the Dial-A-Ride concept that Santa Clara county Transit tried in the 1970s.
Or pretty much any other MVC GUI framework, with modifications because it lives in the browser and renders to a DOM.

Certainly when I first saw it my thought was, "hey someone did Cocoa for the Browser, nice".

https://blog.metaobject.com/2018/12/uis-are-not-pure-functio...

"One way data flow" is pretty much exactly how MVC works, except that MVC decouples a bit more: the model is only allowed to send #changed notifications, the view then pulls what it needs. The data still only flows in one direction.

"Actions" in Redux are very much the "Command" pattern as used in C++ GUI frameworks such as PowerPlant.
Compilers like GCC can produce code specifically for your CPU such that it uses all of the special features you might have like SSE, AVX etc. When binaries are made for general use they have to be compiled with a generic feature set so might not make best use of your CPU.
> The ephemeral "brand awareness" provided by most advertising takes more than a few days to fall off.

Marketing metrics in general move slowly: think weeks, months, or even longer for significant moves. A lot of short term moves are noise generated by imperfections in sampling, particularly with daily collection. This applies regardless of the metric: awareness, consideration, affinity, penetration.

I don't know what she means specifically by "performance metrics", but it would be a pretty poor showing for the CMO of a global company to expect significant moves in any marketing metric over the span of a few days. I'm therefore guessing she means something else - like impressions, clickthroughs, or sign-ups - and that the article is simply of poor quality.

I'm straying off topic here, but generally the only time marketing metrics make significant moves over a short period of time is if something major happens that hits the news or goes viral. Even here it may only be changes in media metrics, such as buzz, that aren't reflected by changes in more substantive areas.

E.g., I can see a gigantic spike in negative buzz for KFC in the UK in late February 2018 because they ran out of chicken nationwide (I kid you not). I can also tell you that whilst over the next several months their penetration dropped by a few percent (significant at the levels we sample), no long term harm appears to have been done to their business: penetration quickly returned to its pre-crisis levels.

The reason nothing has changed could at this stage be attributed to the fact that it's too early, or simply that nobody cares Chase has stopped advertising: they're so ubiquitous it doesn't matter.

And if you're still looking for more reasons why this isn't news, this might be the killer: it's pretty well understood that you're going to get a different response to online advertising depending on where you place it. Some sites simply give you more return than others on your advertising investment, and the differences can be stark. I'd bet Chase has limited their ads to the 5000 sites that give them the best ROI so, again, no surprise that nothing has changed.
A good implementation helps with leaked credit card information if every transaction would use 3D Secure.
I dont need to remember an extra password for my bank (n26). I have to login to the app on my mobile and sinply allow the transaction by a tap. Easy as that, much more secure. I was impressed when i saw itctge first time.
Because the author doesn't want to intimidate new users by making them feel this is necessary knowledge to learn react. As someone presumably more knowledgeable in the field, it's much easier to judge whether an article is at the right level for you than someone just starting out.

I really don't understand your issue here.
You must be fun at parties.

> Aldi supermarkets aren't really representative of Western European tastes.

Sure, what do I know about food representative of Germany as a German. ¯\_(ツ)_/¯
That's understandable. Being discriminated against sucks.
And those options would include the travel times and costs of all available modes.

All available modes, or all available Uber modes? In contract, Google shows you driving, biking, bus, public transportation, and rail all on the same page.
Indian here. Its very easy to get a death certificate. Local newspapers do funny stings where they have got birth certificates and death certificates made of international personalities. Most funny was those of Zarqawi and Bin Laden.
I am not a “beginner” and I appreciate the disclaimer. I value my time: i know the level of the article and i decide to read it when i have more time.
The argument over the removal of options in this thread [0] is brutal. Very intentionally user-hostile move, repeatedly disguised as being in their overall interest. It left me not feeling very good about the direction the project is taking.
