False. When most people talk about dynamic pricing or repricing, it's about competing with other sellers or other retailers. Retailer A may reprice according to what the going price is at Retailer B to try to avoid losing the business. This goes on quite a lot, but it's not on a per user basis because that would make no sense.

People already self segregate into pricing groups: some people buy from high end retailers and other people buy from discount retailers, often for identical manufactured products.

If it's showing different prices to different users it's usually something specifically B2B where you need to have a relationship with some kind of vendor to even see the prices. The public nature of most consumer prices makes it so that this kind of scheme is not all that tenable.

Sure you could show different ads to people who use different devices but most of the time the different prices are the ones you pay to the advertising provider -- the consumers generally pay the same.

When people try to geographically discriminate for digital products you often wind up with a big retail arbitrage trade that appears out of nowhere -- see the market in digital PC game keys purchased in one area with lower prices and sold in another area with higher prices.

>He continued: “The second problem here is that even if I were to switch, we have to understand that the consequences of the switch could quite easily be service degradation. I have, in a way, created a partnership with Google over 10 years of searches. They have literally tens of thousands of emails from me, thousands of points of search data. If I were to suddenly switch to Yahoo or to Bing, that is a massive loss for me because Yahoo and Bing don’t have that data. I can’t easily export that data. That, to me, shows a fundamental flaw in so much of the economics literature, in that it tries to model a unitary consumer switching. People are in very different circumstances if, for example, they used Google for five years intensively, or if they have cultivated a, say, diverse array of search engines that they use.

Wildly overstating how much Google cares about any individual user and how much data is actually available to advertisers or internally available within Google.

For the user if you switch from Google to Bing the change is relatively minor. A lot of people out there probably 'switch' to Bing accidentally when Windows upgrades or they accidentally set their browser to a different default - and may barely notice the difference.

>Again, depends on the site, but many people now have (effectively) supercomputers, so why not leverage some of that?

I'm in a different market segment (as far as you can get from athlete/performance cyclist), but also think they're misjudging the market. I bike almost every day for commuting, grocery shopping, and visiting friends. Also occasionally longer overnight trips for fun. I can't understand why anyone needs the features of this bike, and even if they did, how does this $1000+ bike provide those features better than adding a few accessories to any bike of your choice?

I found that in real life, I noticed no difference with most of the features that command a premium. When commuting, I'm carrying a laptop, charger, and usually lunch. When riding for fun, I'm usually carrying plenty of water, food, and maybe a tent and sleeping bag. So why would I pay hundreds of dollars to save pounds on my bike with a carbon frame?

I do spend plenty on accessories, but they're in the opposite direction than what this bike offers. I bought as nice of a saddle as I could find, with no thought towards price. Same with comfortable hand grips. And a really expensive pannier that converts into a backpack - which is probably my best purchase.

Following that high publicity jeep hack, and I'm sure plenty of other car hacks that have followed, I personally consider it a feature that my bike is purely mechanical. This bike falls somewhere between "social network for dogs" and "smart refrigerator with livestream of your egg carton" in terms of why would I want this?

For half the price of this bike I got a 1500W mid-drive ebike conversion kit that I added to a $150 BMX bike which is ridiculously fun, with a programming cable allows for more than enough tinkering for my tastes. It's in a completely different class than a human powered bicycle for sure, but IMO many casual bicyclists would be well served owning a cheap e-bike and a cheap bicycle.
I wonder when this was actually added, maybe it is getting ready for an actual release in iOS 11 later this year.

It seems like there is no benefit to you at all.

Paying the average amount means you're paying more than some fares.

By paying cash, you lose out on all insurance in cash of an accident.
then they'd basically saying "because you depend on software X and our GPL-software, you need to make software X GPL as well. That probably won't hold in court.
This is a great point: Who's insuring the ride? [..] Lyft/Uber certainly wouldn't owe anything for stuff booked outside their platform.

> this is an improvement, but not an exponential one.

I wonder how you define exponential here. If the old version had a probability 20% of losing against Lee Sedol, and the new one has 5%, then one might call it exponential. Something like losing prob = 2^(2012-current year).
Ways to dismiss technology
Yeah that's what I meant.
It depends who "you" are. If you are a student, your job is to maximize your learning given the instruction provided [0]. If you are a teacher, your job is to maximize your teaching given your students ability. One way to do this might be to train the student to learn a certain way. Another way to do this might be to train yourself to teach a certain way. The optimal solution probably involves having both students trained to learn, and teachers trained to teach. This begs the question of what "optimal teaching" is. More specifically, is optimal teaching lectures? I don't know the answer to this question, but it sure is useful to have scientists looking into it.

>Students need to be able to learn from the world they live in, not from some meticulously sterilized learning laboratory.

So, not from lectures?

This view point is detrimental to the community. Your comment offered no real insight, content, or much of value. It's easily negated by stating the obvious: In a market with such high barriers to entry and few players, consumers may not be able to buy a vehicle without sponsored waypoints.

Is it ever a good idea to 'roll your own' protocol for IoT device communication?
AlphaGo had a fundamentally new architecture (nobody had successfully applied convolutional neural networks to Go before, although of course the headline underestimates the expertise and experimentation that's needed to get the details right).

So it's not surprising that at the first public announcement they hadn't yet pushed the technology as far as it would go.

"EDIT: Autopilot and constant software updates are huge."

Huge, unknown unknowns and huge attack surface, respectively.

Look, as the owner of an Audi A8 that had all kinds of MMI/Nav/Audio bugs, I very, very much appreciate the idea of frequent and iterative software updates - they were desperately needed.

Never once did I ever wish they were provided automatically, over a network connection. Never once did I wish the car even had a network connection.

Some Lessons I Learned from the Dotcom Bubble for the Coming Crypto Bubble
Neat stuff!

I'm pretty sure I saw them out there today stringing some up on my street, and it's reflected on the map.
Millimetre wave Wi-Fi (60 GHz) does not penetrate walls and in practice needs line of sight and beam-forming antennas. The scenarios it is good for are things like docking stations, or connecting mostly stationary devices within line-of-sight to each other in the same room. Definitely not suitable for anything like LTE scenarios.
Out of curiosity, what are the ethical concerns? The arrangement is not being made by the middleman company. I don't see how it is unethical to not pay them for something they did not do.

Point (B) doesn't make sense to me. Why do you have to accept and then cancel? You just get the driver's phone number and talk to them directly.

In fact, if this is not common already, I think it undermines the contention of these companies that they are merely a service being provided to independent contractors. If drivers are independent contractors, of course they should be trying to build their own brand and dedicated clientele.

Point (A) is a good one, though. Sounds like there should be independent insurance providers that these independent contractors can use.

If you're instead saying that drivers are employees of these companies, then maybe you're right about all the rest of it. But you can't have it both ways!
FWIW, not all immersion programs in the US are charter based. Our kids went to a public non-charter Spanish immersion school K-8 here in San Jose, and entry into the school was split equally between native English and native Spanish speakers. That meant there was good diversity in socio-economic backgrounds without any direct "racial profiling". (Note there were also some upper-income native Spanish speakers in the program, mostly kids of immigrants from Spain and South America.)
This is great. And true.
previously built out a large price tracking system across numerous online marketplaces and retailers. Things that impacted pricing:

Time of Day, Time of Week, Year etc.
Previous Shopping
IP address/Geographical Location
User Agent String (includes most info regarding device type, brand, model, browser etc)
and more...
The problem isn't the fallback to cellular but the function it uses to detect whether the WiFi is actually working. It works if there's a gross network failure but fails to detect networks which have packet loss, captive portal pages which cannot be loaded, etc. With the exception of captive portal pages, this isn't specific to the WiFi implementation either – the cellular stack is just as broken.

As far as I can tell, this comes down to two problems: the most obvious technical challenge is the difficulty of detecting soft failures rather than hard failures. What they need to implement is a hard timeout which resets the connection state if the remote end fails to respond correctly within a set interval. I encounter this regularly commuting on the subway or taking underground tunnels between buildings; toggling airplane mode is the only way to get it to accept that the base station (WiFi or cellular) it was talking to 1500 feet back is never going to start responding.

The social problem appears to be that nobody considers this a keynote demo feature and so it hasn't advanced beyond iOS 1.0 despite years of bug reports.
Yeah. At first is was pong. People figure out how to send fake scores really easily, myself included.

Chipotle Reports Findings from Investigation of Payment Card Security Incident
The difference with Homejoy was that many people on their site already had existing cleaning companies. They were using Homejoy for customer acquisition. Once that customer was acquired, there was no need for Homejoy. Once Homejoy was out of the picture, the cleaners regular liability insurance would still be in play. Obviously there were some cleaners that did not have a business.

The difference with Uber/Lyft is that these drivers don't have a business outside of the app. Therefore, once you eliminate the app, you eliminate their commercial insurance and it becomes a really interesting situation if there were ever an accident.
Most people who run away get caught because they tried to contact someone from their past life. If you're willing to lose everyone, it's possible.

Average users don't care about encryption either, yet we still have the padlocks for those who do. More importantly, average users are not creating browsers, and the people who know better can't hide behind them.

The average smoker probably doesn't want to hear smoking is unhealthy. Does that mean doctors should adjust their advice respectively? At what point does "professional" really mean nothing other than "gets money for it, like a carpenter or a thief or a drug dealer might"?

We don't even have the right to "just give people what they want without any judgement on our part", but we certainly don't have the right to ignore those with legitimate concerns because ignorant or apathetic people are more in numbers. That goes for everything, everywhere. That goes to how you are supposed to look out for little siblings when parents are away, and it goes for expert knowledge or intellect.
If many people accept it, cars that don't do that may be considered a luxury sold at a premium price. You may not be able to afford such cars.
A much welcome public statement on this matter. When I was teaching and I chanced upon a colleague who was overzealous about the learning styles theory, I used to respond - if you had a child whom you pegged or tested as a "visual learner" and you wanted to teach him how to distinguish between different bird calls, you'd seriously have him do something like study oscilloscope graphs of the sound waves rather than having him actually listen to the calls?

Taken to its logical conclusion, it defies reason and even basic experience that any knowledge and skills can be better transmitted when conveyed in the modality that lies in learner's unique strengths.

Notably, it looks like Google, Facebook, Netflix, and Uber are all using it (or have a dependency that is). There's been a handful that were using it since early 2015, and a surge of several hundred towards the end of last year.

> Pre-exploitation population estimate of 239,000 (95% interval 202,000–311,000).

> Estimated 1996 population size, 1,700 (860–2,900)

Don't use three significant figures when your confidence interval spans 50% of your estimate. "200,000 to 300,000" would more clearly express the data.

And be honest about accuracy: if modern satellite, aircraft, and naval technology can't pin the 1996 value down more tightly than "half this number to double it", you can hardly say with a straight face that your confidence interval on the 1800s data is "minus 15% to plus 25%".
People having preferences doesn't mean it's good for them to always have those preferences catered to or that their preferences actually match any empirical evidence evaluating their personal learning performance. It's even possible that people might decide "I don't learn this way" and tune out in situations where they could still learn if they latch onto only using their preferred "style."

"It has no luxury features."

That sounds very much like a Model S ...

Go look at the interior options and features (and materials and fit+finish) of any mid-range luxury car (5series, E-Class, A6) and the Model S comes nowhere near in terms of luxuries and amenities and functions. Never mind the actual high end cars that the Model S is supposedly competing with (7Series, S-Class, A8).

They play it off as a very modern, minimal aesthetic but they're not fooling anyone - the interior is sparse and cheap and poorly executed.

There are still more mundane questions about engineering ethics. Your boss is pushing you to get a feature done by the end of the week, but doing it properly would take at least a month. You could finish it, but doing so would lead to increased maintenance costs, inconvenience/costs to downstream users/ etc. What are your ethical obligations here. Blindly listen to your boss, make sure your boss is aware of the engineering trade-offs being made and has made an informed decision on the timeline, refuse to deploy sub-par code, quit, leak about poor engineering practices, publicy shame about poor engineering practices?

The Gatto essays are remarkably concise and convincing. I'm very sympathetic to that critic.

relatedly, Ivan Illich "Deschool Society" [0] is another author that wrote in depth on this subject with similar incisive critiques.

also, Darren Allen writes on the institutional nature of modern society [1] and the way we are conditioned to become subservient to its structures [2].

all of this begins in elementary school and it's sorting of children into groups. The conditioning of children into being "manageable" components in an institutional indoctrination system is at the heart of how the system perpetuates itself.

I think the key to the article is that when the ride is booked in advance, the driver sees the route and destination. A big compliant from drivers is that you accept a ride and you don't know if you are going 1 mile down the road or 100 miles to the middle of no where. Now the driver can see before accepting the ride (for these advanced booked trips).

> It used to be that education was something people did for themselves

Not really; for most people for most of time education, such as it was, has been narrowly directed from outside at a particular pre-ordained social role.

The luxury of self-directed education has been rare, and mostly available in fairly narrow social strata where it has been available at all (and often some high-middle stratum more than actual highest elites, because the latter often had stricter expectations with less flexibility.)
Taken from Wikipedia:
"Since lower socioeconomic groups and children with learning and behavioral problems have lower rates of participation in French immersion, a situation has developed in which ambitious families might prefer French immersion for its effective streaming than for the bilingual skills it gives to students."

I don't see how this is a problem, as you've noted it.
I can see why some people might use to-do lists as their go-to, but those often are not representative of actually exploring a language.

I guess there is probably a large community of people who only share publicly projects they consider portfolio Worthy. I have found sharing valuable in both failed and successful projects when interviewing, teaching, and spec'ing a new project.

You're correct in noting that some of these projects fail, but as long as there is sufficient code the projects they can often be interesting.

Sort of side projects that I pull together in another languages are often to explore language features that are not readily available in my common tongue. Certain languages have made completing certain tasks far easier like heavy Matrix programs in Octave or Julia, n-body simulators with extended unit types in Julia, multi-threaded cryptographic toy project in erlang, statistics problems and visualization in R, easy concurrent types and strong explicit typing for model train controller and Ada. I have also used a new language for a interview coding challenge (for fun).
