It is a pretty excellent controller. It's kind of amazing how many keyboard/mouse only games you can comfortably with a little tweaking of the keybindings.

I haven't tried using it directly with my computer, just for couch gaming with my TV and Steam Link. The Steam Link is also pretty cool, but has some serious issues with crashing Steam on my PC - not sure whether it is the Link itself, or Big Picture mode, but it is super irritating to have to get up and go restart Steam in the other room when it craps out in the middle of a game.

If you're familiar with the Time Value of Money [1] you can compare the discounted future revenue streams from the non-profitable subsidiaries to their current cost of operations (vs. a sale price).

Boston Dynamics is, conservatively, more than 5 years off from having a product that anyone will purchase (the marines don't want their bulldogs). Other non-profitable ventures may have more near-term revenue streams that outweigh their present cost of operation.

Hope that makes sense.

I always thought it was a slightly odd acquisition for Google. Didn't seem like it would really fit with Photos use case, and I suspect, sadly, that you are right.
That Google car which hit the city bus "should have" changed lanes immediately (if the coast was clear, and if we're just talking reaction instead of having the human sort of prescience to slow down to allow the bus to leave the stop) without using its blinker for a sufficient amount of time. I think the guy has a point, somewhat. What about a car that has a choice to hit a person or a crowd and nothing in between? Maybe I'm using a bad example, but I do believe that there are situations when the only choices involve breaking the law, and I do believe that someday robots will be in those situations. Those situations are not by any standard the norm, but they do exist.
Big trucks do pay a substantial road use tax. I don't know the specifics, but they don't get to drive for the same cost as the passenger cars. On toll roads the trucks pay a lot more too.

A train seat is not the thing I am paying for. A transit company is typically chartered around provision of service regions and schedules, and it has the power to divert passengers to alternatives like buses if problems arise preventing use of some existing infrastructure. The customer is not there to "ride the train" but to reach a destination - the transit is judged upon how well this demand is satisfied.

Private property law allows owners to enforce their own rules(to a point). This both explains the private control over the train and tracks and lends weight to the possibility of being kicked off the train, as it is justified in terms of disruption to service and resulting monetary losses. To wit, a positive externality of transit service is economic gain from the population having improved market access(more goods, services, workplaces within reach). The transit company does not realize these gains, the public does. The company's enforcement of rules is guided by the premise that some amount of security and order is necessary to achieve its service goals.

Sure they do;

• MST3K-izations of movies are plentiful. But there's a higher bar to them; viewers expect the commentator to be enhancing a movie that might otherwise be unwatchable, not just adding their thoughts.

• "Directors' commentary" (and "actors' commentary", etc.) audio streams are also plentiful. If someone's opinion on the movie as it progresses would be specifically interesting, then people will want to combine the two.
I've integrated Braintree for monthly recurring subscription services and for digital product purchases. For my own purposes, I built my own cart in Rails as I needed a degree of flexibility in check-out.

So far I haven't run into any problems. The only thing I really needed was to customize customer e-mails, so I used Braintree's webhooks to my server to send out my own e-mails.

Support wise, I was on the phone with them quite a bit in the beginning, and they were nice and knowledgeable. I used them pre-paypal and post-paypal i haven't noticed any differences.

Fraud wise, my customers tend to be reliable ones so I haven't had to worry about fraud yet.
Try visiting Brisbane, Australia. Its fleet of busses are all air-conditioned and run on natural gas. There are dedicated bus-ways [1] and a bridge to the university that only busses, cyclists and pedestrians are allowed to use [2]. Brisbane is one of the most spread out cities in the world, but its bus network and smaller rail system make for a decent public transport system.

Let's say that 500,000 cars (100k/car, pricing in the cost for storage and maintnance). The most Expensive subway line in the world cost 15 billion and serves something like 800k people. So you could also use that money to build two subway lines and save for maintenance. You could probably build 4 light rail lines (since you're not digging tunnels but instead buying up land).

Plus rail incentivises denser living, meaning that the more rail lines you build, the shorter you need to make them. Self driving cars let you share the cars so kind of solves the parking problem (but keeping track of people doing nasty stuff), but is really just a bunch of micro-buses.

If you can get the political will for rail, it's a pretty effective way of moving people around.

Your post is a good example for why cascades are so dangerous.

hash1(hash2(...)) is not as secure as the stronger of the hash functions, it may only be as secure as the weaker of the hash functions. Your example is sha1(md5(...)). Well, md5 is no longer considered collision-resistant, which means that sha1(md5(...)) also isn't collision-resistant. If you're able to obtain two different inputs that are mapped to the same hash by md5, computing the sha1 of that hash is still going to lead to the same value, i.e. a collision overall.

So your assumption that an attacker must defeat both is clearly wrong and dangerous. In the case of hash functions, I believe it would be safe two concatenate the hashes (instead of composing the functions), but now you have a bigger hash size in addition to a slower running time.
> sha1(md5(things))

Consider what would happen if the "md5" function was found to always return the number 3 for "things" greater than 999 - the "sha1" function would be no help. The entire chain is only as strong as the weakest link. It doesn't matter how you mix the inputs, any biased input weakens the system.
Now I can't wait for that episode where a greyed Ross Gellar has a guest appearance on The Big Bang Theory.

Neural Turing Machine in Tensorflow
I'm sad that every explanation of MCMC uses complicated symbolic explanations. I was trying to explain it once and came up with a fairly intuitive way to visualize it. Probably that is the way it was first discovered, though who knows.

In words, you can visualize it as doing a random walk around the area of a probability graph. Then it just turns into an explanation of why random walks accurately sample from an area, and the various tricks used in MCMC methods to make random walks more efficient.

Relatedly, bayes theorem makes much more sense when you visualize it, e.g. this post: https://oscarbonilla.com/2009/05/visualizing-bayes-theorem/

The problem isn't that people choose routes that are strictly non-optimal, it's that they choose routes that are optimal for them - essentially using a greedy algorithm to choose routes. This is why closing roads can actually improve traffic in certain scenarios. Google Maps won't solve this, unless it starts suggesting routes that are optimal for the network instead of the individual, which is unlikely as they cater to individual drivers. Truly optimal traffic would require central route planning of some sort.
And neither does light rail. light rail is a bad investment. It is expensive and low capacity. It is 19th century technology.

Building bus rapid transit makes much more sense because it is felixible and less expensive. But politicians don't like photo ops with buses nearly as much as with trains.

So... This is just a human thing, I think. I was raised in a university town, in a neighborhood which had a lot of (poor) students with children. Lots of immigrant students, too. Anyways, nearly all of my friends were Chinese nationals whose parents were involved with the university. When they first arrived they spoke zero English. It was just the thing to do to teach them first and foremost the nastiest curse words in the English language. When I went to live in Germany, it was the first thing I learned from my new German friends. This is just some sort of reflexive human behavior. We shouldn't expect people to treat robots any differently. And thinking about it, there might actually be some kind of indicator buried in here, of how human beings psychologically react to robots.

> Most of my historical fraud has happened because I probably swiped my card at a location that was compromised.

I travel a ton and also do all my shopping online, for years. I have to replace one of my three credit cards every 3-4 months. That is usually within a week or two of visiting a gas station or taxi, places where they don't use chips and in the case of taxis still have the gall to use the paper carbon copy machine things. Whatever though, when a card gets lifted Chase takes care of the charges and overnights me a new card wherever I am (even international).

Although I've had many notifications over the years about my card data "possibly" being compromised in some online breach, I don't know that it's every been a real issue.

This service makes sense if you don't have a (real) credit card and for some reason want to link your real cash account to a payment service. Otherwise I don't think I get it, or why I would forget my credit card, anyway.
Traffic is a compression wave. The car in front of you accelerates, then you accelerate, then the person behind you, etc. Same for slowing down. Self-driving cars would presumably synchronize, allowing all of the cars to start moving at almost the same time.

Also, people don't feel safe driving at 60mph in a densely packed road, so they don't. This should be no problem for a computer, so you could have a densely packed highway but traffic still moving at very high speeds. Basically, flow velocity could remain constant as the highway becomes more congested.

Another optimization that comes to mind is that on city streets, your car would route around traffic light timing.
No, because in markets where most people pay, they aren't optimized to be costly addictions. Mainstream video games charge every player $50 one time, instead of charging 1 player $5,000 and 99 players $0.

They may be able to still bill you and you may be legally obligated to pay, you are just taking away their way of automatically collecting the bill. You may still actually owe the bill; just because you didn't pay a bill doesn't mean you don't owe the money.

All this depends on the company, what you signed up for, if it was a contract, the TOS, etc, etc, etc.

For a real silly example to illustrate - lets say I signed up for Comcast and gave them a single use credit card number for automatic bill pay. When the second month comes around they attempt to charge my credit card and the card is declined. That doesn't mean I suddenly don't have to pay my Comcast bill, it just means they can't collect it automatically. Comcast will take a few months to cut off service[1] so you'll end up owing them several hundred dollars. Eventually if you don't pay they could send you to collections. Collections can take you to court and then when they win they can garish your wages, etc, etc.

Yes, I know this is a silly example and its unlikely to happen with the majority of "free trial" services on the net but that doesn't mean its responsible to basically advertise "yeah, just give any company a temporary number for a free trial and forget about it." Especially since a lot of services with a free trial are with companies that have a lot of resources.

A less silly example would be if I signed up for a gym with a two year agreement and a year later I canceled my credit card and stopped going to the gym. In that case the odds of me being billed further and sent to collections is very very high.

[1] they do that around here, I know someone who only pays their Comcast bill every 4 months or so...

> The majority of popular mobile games are a costly addiction, not a hobby.

Precisely. And to a large extent I think we're lagging behind the proper realization of what's going on here. A lot of "freemium" mobile games play in the same space as gambling does, and they hook into the same cognitive, behavioral, and reward mechanisms in order to hook people's attention and keep extracting dollars from those who become addicted. Hopefully it's not nearly as damaging as gambling addictions because there seems to be a somewhat slower curve and lower cap on spending, but it's still pretty bad.

Fair enough about the bespoke products.

But does anyone really do this? Are there published examples of people doing this or talking about doing it? I can find plenty of examples of hedge funds betting on single mid or late stage startups but not doing what you're suggesting here.

What you're suggesting is incredibly interesting so I don't intend to be rude but the concept strikes me as ludicrous. The assumptions that would go into a financial model for something like this seem ridiculous to me. You'd be betting/guessing/hedging on countless company, industry and macro-economic variables over a long, long time frame.
> Our infrastructure is crumbling because we do not collect enough taxes to subsidize it.

That's just not true.

We have crumbling infrastructure because we refuse to prioritize it due to political dysfunction.

If youre a surgeon or a lawyer living in San Francisco, your marginal tax rate is 39.5% federal + 11% state. Over 50%. You also pay 8.75% VAT on a lot of common purchases and 1% property tax.

This is not a low tax environment.

Hong Kong has a 15% flat tax and yet they have vastly better infrastructure than we do. Singapore is a similar story. Even Istanbul, with per capita income and tax collection thats a small fraction of ours, has a great light rail system that puts Bart to shame. Istikal Street is incredible--imagine Market and Mission put together, and pedestrian only. It is a beautiful city.

So how do these places do it?

* They respect and prioritize infrastructure

* Their governments are less gridlocked

* They value density and walkability

* They have fewer NIMBYs, with much less power to obstruct

* They're less lawsuit-friendly. In the Bay every big infra project spends time and money fighting lawsuits.

* They have leaner bureaucracies. BART has tons of six figure salaries on the payroll for random adminstrative positions.

Cities can't impose local income taxes as it is politically difficult.. Prop 13 means they can't get money from increases in rents, and they don't want to build more anyway. As a result cities don't see the gains from booms in the way they would in other regions of the country.

Mastercard has this service in quite a few countries, the downside is that usually they do not offer the same insurance as for the normal cerdit card and those cards will not pass an actual credit check.
Other issuers, banks, and other organizations (post office for example) also offered similar services.

I never really liked these services they don't really support recurring payments, some of them force you to purchase a card with a specific amount rather than it being valid for a specific transaction, some times they have issues with various 3d party checks (pre-paid card check, region lock/address verification, fraud etc.) and more importantly it's not an elegant solution as you end up with allot of credit card numbers.

Overall while this one might have a nice UX it doesn't really solve a problem that hasn't already been solved either through Paypal or trough your own credit card company.
I can see all payments on my Amex and Visa cards in the UK, I can check which ones are recurring, I can initiate a charge back and for everything else well there's paypal which offers even an easier UX.
