My understanding is second stage is harder, first because of the rocket equation. Every Kg on the second stage is much more costly than an additional Kg on the first stage.

Second, the second stage needs to go into orbit before it can return. That's much more speed and a harder reentry.

Third, you have to deal with thrust. Falcon 9 has 9 engines, which means the landing burn can uses 1 engine for 1/9 of the thrust. This is still too much power and F9 currently needs to do a suicide burn. You can't do that with only one engine on a stage that is 1/10 lighter than the first one.

Fourth, second stage has a vacuum engine with a nozzle not fit for atmospheric use. It's so thin and flexible it would probably crumble or disintegrate upon entry.

As far as I can tell the problem is a series of disconnected motives. The VC's have money to burn and want to become the next level of rich, which requires striking gold, often in fields they have no real conception of. The "disruptors" also want to strike it rich, but they can do that just by getting the VC capital and chalking the devastating losses they wont' personally suffer up to "valuable experience".

Then of course success isn't necessarily contingent on providing a reasonable service at a sustainable price... see: Uber.

Generally, it is not the technical side of the ISP that gets a lot of hate. Anyone in IT should have a reasonable grasp of just how hard networking really is, so IT people should have a good feeling of how much harder than that it would be to operate at the provider level.

What ends up being the anger issues are the purely commercial/business side:

The business decision to spy on users for advertising profits.

Their actual regional monopolies that skirt the law because there is national level competition.

The inconsistent pricing and massive numbers of fees that are just pure profit. (Not the few actual taxes.)

The close ties to legacy entertainment leads to a naked conflict of interests.

The political fallout from the FCC enforcing basic rules that actually built the majority of the internet culture before it went big business.

The service that ISPs provide are outstandingly expensive with a glacial pace of new technology roll outs. We know it's hard and expensive, but that's not an excuse to do literally nothing but collect profits. FiOS is the perfect example... NYC is suing because they took grant money and tax incentives, then utterly neglected the agreed upon course of action.

Internet service should be a deeply regulated utility like water and electricity. The strict price controls offset the regional monopolies model. The companies that run ISP should be legally required to be independent from non-ISP business interests, like cable TV, Entertainment, or phone services. ISPs being divided at the last mile from the core plumbing of the internet also sets up a deeply adversarial relationship with the backbone providers. Integrating those two realms into regional entities enforcing interconnectivity rules would reduce the Net Neutrality issue considerably.

None of those will ever happen, however. The lobbying against enforcing utility rules that mandate the profit margins would be extreme.

Deep Compositional Framework for Human-Like Language Acquisition
Roll your own. Start with a subscription table with a paid_through column, and a payment table for recordkeeping. Your billing code is a daily cron job running a single simple script, that selects all rows with paid_through less than current date, charges each user's card on file, and updates the two tables. Discounts, different subscription terms, receipts, dunning mails are all simple additions to the daily billing script that you can add as you grow.

This has worked for me with tens of thousands of customers and millions in billings, and I've never had to worry about being locked into some payment company's proprietary system. Whatever pricing scheme you initially come up with for your app probably won't be right. You might have 6 plans when you only need 2. You might find out you were charging a flat monthly rate when you really need to be charging per widget or per user or per server. The more you rely on someone else running your billing, the harder it will be to experiment and find the right way to do billing for your customers.

You can avoid being locked in to a payment processor for storing and charging payment info too. I use Spreedly (https://www.spreedly.com) which provides payment card tokenization and a single unified API for over 100 payment gateways. I can use Braintree today, Stripe tomorrow and ShinyPaymentStartup next year without changing any code or re-collecting billing info from customers.
I'm guessing the fact that Oculus is a distant third in VR market share (without even considering headsets such as Cardboard and Gear VR, which would put it even further behind) didn't help.
Steve Jobs said it best:

"[Dropbox] is not a product, it's a feature."
Let's look at an analogy: Amazon Prime delivers in a day by now. With the customer info, Amazon can also send stuff directly/monthly. That's HTTP2.

The user chooses several products in one order. When you add the product in the basket, Amazon suggests some products that are often ordered at the same time, like extra supply or accessories. That's GraphQL.

GraphQL assumes shipping something cost money, and forces the client to declare what it wants explicitely and in detail. Like SQL without SELECT *.
Hope that helps!

It's not so much as "should we?". I mean I don't want to put any moral assessment here. The truth is we don't quite know what will happen. Some of the scenarios are great, others are ugly or sad. Like for instance the idea that to reach happiness, mankind could use biochemical ways. To reach immortality and thus safety, we could chose claustration. That's the caricatural scenario where to make us "safe and happy", AI would lock us in jails with an abundant supply of heroin. A similar one is the one described in "The Metamorphosis of Prime Intellect"[1], which I like because it reminds me of a famous experiment that I find fascinating[2]

We don't know if changing ourselves would be for the better or the worse, but it looks that it will happen anyway and that will be consistent with the prediction that AI would cause the disappearance of Homo Sapiens, or at least its relegation to the status currently occupied by other mammals.

Canada does allow a limited number of refugees to enter, but for the most part our immigration system isn't altruistic. We don't allow people to enter and stay on the basis of their need to live here, but on our need for their skills. We have to have an expectation that immigrants will earn a reasonable income, or they will become a burden on our already strained social services. If they are unskilled (i.e. poor) or their skills are not in demand in Canada, then we can't afford to allow them to stay here in poverty.

A lot of people here with their TV law degrees are giving you gibberish answers that pleading the 5th doesn't imply anything. They are wrong.

The fifth amendment is only available to avoid testimony that could potentially implicate oneself in a crime. Proper exercise of 5th amendment rights cannot be used against a person in a criminal prosecution.

This isn't a criminal case (yet). It's a very high-stakes civil case. Pleading the fifth may result in an adverse inference jury instruction, or an adverse inference determination by a judge in a nonjury trial. In other words, it makes you look very bad, and the finder of fact is free to assume the worst.

Not applicable here yet, but in rare cases prosecutors will also get around the 5th is by offering immunity, in which case you may be ordered to testify, and your testimony cannot then be used as evidence against you in a criminal trial; refusal to testify under immunity can result in punishment for civil or criminal contempt. You cannot invoke the 5th to protect yourself from civil liability, or to avoid implicating another person in a crime.

There's all sorts of things that "pleading the fifth" doesn't protect you from. For instance, public employees are often required by law to cooperate with all public investigations, including criminal investigations. Pleading the fifth as a public employee in an public investigation can result in mandatory termination, even if there is no evidence of wrongdoing.
His lawyers could have convinced him to ask for immunity if there was even a slight chance of legal trouble. He may also only have some minor dirt to spill, so he's happy throwing some staffer under the bus.

> If you don't see the problems that Islamic fundamentalism is causing in Sweden and Germany, you are willfully ignorant. The way Islam is practiced in most of the world is incompatible with western democracy. It's anti-woman, anti-gay, and anti-human rights in general.

There are a few thousand Islamic fundamentalists in all of Germany and the problems they cause are pretty small-scale. The way most Muslims practice their faith here is rather not-in-your-face. E.g. I recently asked a friend of mine whether he wanted to get a hot dog, when he told me he doesn't eat pork. I had no idea. So then we got falafel instead.
I recently started making an app with the combination of Apollo Client and Scaphold (http://scaphold.io), and I can't get over how easy it is to rapidly built an app.

Nobody yet has mentioned the big picture. To me the big queston is: How the fuck do Levandowski and Kalanick still have jobs at Uber?

If I were on the Uber Board of Directors, I would be pushing for armed security to escort those two clowns out the door. Immediately. As in today. And I'd give them a cardboard box with all their personal shit in it for them to carry out with them.

At what point in time does a company Director become complicit in theft of IP? What did the Uber board know, and when did they know it?

I predict that, any day now, there will be mass scurrying of rats abandoning a sinking ship.

All IMO of course. As they say on the TV show Cops (more or less): all suspects are innocent until proven guilty in a court of law.

This is a really weirdly-written post! I think it needs some serious editing before it's worth reading. This sentence jumped out at me:

"This is natural enough for all IT suppliers, which triple their revenues when they start going up the hockey stick curve, than then they double revenues for a while, then it cools down to maybe 80 percent growth and then 50 percent growth and then 25 percent growth and then the rate of change gradually slows until it matches the overall rate of spending in the IT sector overall."

All the stuff between "triple their revenue" and "gradually slows" is redundant waffle.

I think Kalanick has a majority of Uber's voting shares, so neither the board nor anyone else can force him to leave. Likewise, if Kalanick wants Levandowski to stay, he stays.

Great paper that perfectly exemplifies what a "modern" philosopher does and thinks about on a daily basis. Unfortunately, it's also a paper that is often read only in lower-level philosophy courses. In my opinion, one needs to have a very deep understanding of the Philosophy of Mind corpus before being thrown into this paper because an uninitiated reader may be tempted to think that Nagel is obviously right on X or obviously wrong on Y, but his points are very nuanced.

Nagel is also making some pretty big claims, specifically about the "private" nature of experience. Anscombe (whom I also loved reading) makes similar arguments. Philosophy of Mind was never my forte (I'm a logic and ethics guy), but reading Nagel was always a breath of fresh air in what I think is a subfield marred by unnecessary technicality and equivocation.
Unless I've overlooked something, the NDA seems to work largely against Airbnb. It limits their liability to this payment, and compels the host to provide "reasonable cooperation", but on confidentiality it only states:

> I acknowledge that the existence of the payment by Airbnb and this Airbnb Payment Agreement are confidential.

There seems to be nothing stopping the host from continuing to assert "Airbnb customers wrecked my flat; Airbnb provided terrible support and miscalculated damages".
Oculus needs 3 tracking devices for room scale, and is still smaller and buggier. Games are required to be designed for 180 degrees instead of 360 like the vive.
Vive is also getting wireless headset support this quarter (TPcast).

Oculus poured far too much money into paying off developers for exclusive titles than trying to compete on technology, and as far as I can tell are falling further behind.
It's crazy how the section about dealing with the police is nearly double the size of the rest of the chart.
I don't think that works if there is truly criminal culpability here. If you're on the Board of Directors you can fire the clown or you can let him vote you off the board. You don't get to say: I can't do anything because he's the majority shareholder.

I initially charged 9$ for my desktop shareware product. This was 7 years back. I thought the app was worth only 9$ that time. But when I understood many people purchased it, I increased to 19$, then 40$ now, but with many more features over the time. I make an average of 800$/month. Stopped using Stripe because of their heavy chargeback fees and bad dispute mechanism. Uses only PayPal to accept payment.

Thanks, but that isn't at all what I am talking about. I am talking about a research service, not a moving service.

If you have ever participated on Metafilter's AskMe, it is fairly common for people to post a question along the lines of "I have this list of criteria for where I want to live. What cities match it?"

Of course, AskMe is a free service. Answers are provided by bored people hanging out online who like answering questions. It is incredibly common for people to answer such questions with "Oh, you should move to (city I live in currently or have lived in)."

But I have a certificate in GIS and I am a former military wife. I have done a lot of moving and I am good at this kind of research based on actual objective data and stated criteria.

I use sites like City Data and Best Places to do some of my research and I know of sites that will let you fill out a form and get a list of cities spit back at you, such as this (which may be dead): http://www.findyourspot.com

But I do not know of any service that will do custom research for you and give you, say, three cities that fit your criteria as closely as possible.

I enjoy doing this kind of research. I would like to create a paid service to do this.

Not sure if this exists. I wouldnt think to even look for such a thing. I would assume most people move for work, other than software engineers.

Not sure about price, I do have some thoughts about marketing however.

You will need to assure people that you have their best interests at heart. That you aren't pushing people to places that give you the best commission, like people think about job recruiters.

You would also need to convince people that you are an expert on a variety of subjects. Local culture, schools, job availability for a given career, weather, house price. Just to name a few.

I might start out with a cheap app, where they can enter basic preferences: job or jobs they work, if schools are important, house price range/ratio of salary to house, rural vs city. Then I would upsell them to consulting services where you address things like culture, ways that the location is different from where you are, etc.

Sorry if I couldn't be more help.
