I'm still unconvinced that Uber's market is one where the first mover has much of an advantage. What prevents those with more marketing and logistics resources from sitting back and waiting for Uber and Lyft to force the social/legal change that creates the industry before entering the market themselves?

Right now, the deep pockets want nothing to do with that business because the future is uncertain and there's a large liability risk. One of many probable ends for Uber and Lyft is being sued out of existence ala Napster. But if Uber succeeds in proving the market, competitors will follow. What does Uber have that's hard to match? Their technology can be replicated by those that know how to build software. Their drivers will bolt to any competitor that will pay them more. Their customers will bolt to any service that's cheaper. Without some sort of network effect, they'll either fail in their legal challenges or they'll find themselves in a race to the bottom and see their margins evaporate.

Worse yet, they could see themselves competing against companies that can bolt the Uber revenue source onto their current product. Facebook Transport, which leverages your network of friends for stuff like trusted reviews from people you know. Domino's ToGo...a ride home and a pizza. Amazon Local Lift...handle your grocery shopping on your way home. And that's not even considering if Google gets to self-driving cars first and decides to compete rather than license/sell the technology to Uber.

At the moment, Uber and Lyft feel like the penguins that gets pushed into the water to test whether there's a Shark or Whale nearby. They're either going to get eaten, or everyone else is going to follow them into the water.
Look if you've got a hot business with many people pursuing you the world is your oyster.

However most businesses, traditional ones, and even ones that are on the web, don't have that leverage. They will get literally one ready willing and able suitor who comes along (and will pay a good dollar) and so they will have to take advantage of that opportunity. I'm not talking about people accomplished enough to be able to hire investment bankers to shop their business.

It's not that I disagree that much with what you are saying and obviously you shouldn't spend a great deal of time on this either.

Lastly people tend to feel as if they could sell at any time maybe perhaps because they've had some inquiries from time to time.

Obviously there is no disagreement as far as working on the fundamentals of the business. Otoh if your intention is to sell there are many things you can do to package your business to make it more attractive to buyers along the way.
I'll stick with a wireless mouse and keyboard for now. The device in the video looked incredibly painful to use. Strange how the producers did not see that.

Wow, really exciting!

And I know I am (not) being paranoid, but imagine how excited NSAs of the world all will be! A new kind of keyboard, that has capabilities to understand and predict what the user will write? This just looks like something Facebook could also be interested into (if you think at their "I keep what you wrote and deleted before even publishing" attitude).

This kind of tool really needs to be open source and open hardware. Otherwise they better stay far away from me.
If we were to take this article as truth -- specifically, the part that fasting can activate dormant stem cells, then fasting could very well be a bad thing.

There was recent research done that suggests that stem cells are a key ingredient to long life [1], and if they were to, say, come out of dormancy and become active too early and die, then you have just shortened your life.

Yikes!
>Relieving Europeans of responsibility for their own government guarantees American power over them

It's not like Americans have any greater "responsibility" over their own government.

It sure doesn't work for their best interests -- only for the same private interests and multinationals that also take advantage of Europe (and all post-colonial countries in their sphere of influence).

And it's not like European elites do not benefit from that -- it's just that the majority of those people tends to reside across the Atlantic, and finds it easier and more effective to yield US as their own private economic/diplomatic weapon. For the actual country and the majority of its citizens, they could not care less.

>They can complain while still feeling righteous, brilliant.

Not sure how "feeling righteous" is contradictory with "complaining" (your phrasing seems to imply that).

Your message seems to be: "if you're fucked over by a bully, you don't have the right to complaint, because it's your responsibility to stand up to him".

Well, replace Europeans with black people in the South pre-Civil War. Does that retain the same kind of ring that you intented it to have?
Even with revenue projections and being able to work back to personal gain, employees often aren't privy to liquidation preferences and the variety of classes of stock that has been handed out. If an employee has 1% of a company and the company sells for $100m, the employee rarely sees $1m.
So the "damaged" class is not really damaged. It's what you'll wind up with if you started with a small rails project and you had to scale it as it got popular? hmmm.
This kind of cynicism is getting tiring. Being cautious about your personal information is good, but how exactly is this any worse than a bluetooth keyboard? OS X and iOS already have predictive typing with regular keyboards. There is no need for FUD.

>I mean, you want to talk about ironic: Consider the atomic bombing of Japan. To the extent that it contributed in any meaningful way whatsoever to avoiding a land invasion of Japanese (American, Soviet, or both) it saved more Japanese lives than died at Hiroshima and Nagasaki combined, to say nothing of the Allied servicemembers staring down the barrel of the Japanese gun.

Yeah. Shame that no bomb and no invasion was necessary either, the Japanese were already literally begging to surrender, and they only asked for a few trivial conditions in exchange. It was just a way to live test the bomb on people, send the world a message, and kickstart the cold war to not let the Soviets get any ideas.
Well, you're more explaining why not to mock, rather than what they mean by not mocking... but I have a hard time agreeing with this, for properly designed code. Referring to my earlier example of B calling C, what if B's business logic is complex, but makes no outbound calls except to C, and C (for simplicity's sake) is also complex, but returns only a boolean result?

Mocking has real value there because you can control what C returns when testing B. You might write tests for if C returns true, if C returns false, if C returns null, or if C returns some general exception. There, you're testing that B behaves correctly, given all possible responses from C. At that point, you've controlled the interface between B and C, and limited the ways that C can respond. Because of that, you can be sure that if your test for B fails, it's because of a problem with B.

If you instead don't mock C, then an integration test that tests both B and C (since B is actually calling C) becomes a lot more complex - probably more than twice as hard to nail down a bug.

The trick there is that by focusing on the unit test, you've written a clear, simple interface between B and C, when you might not have otherwise. I think that's an example of how mocking can really help, and how it doesn't lead to the nightmare of mocks-calling-mocks that a lot of people seem to criticize. And rather than being only useful in cases like protocol handshakes, it seems frequently useful, such as in wanting to mock a dao layer when testing a business logic layer.

At any rate, that makes it sound like by not mocking, they're merely doing multi-level integration tests. I just would have expected them to be more focused on unit tests, which to my mind requires mocking if you have a multi-layer application.

Jim W. made the same point about "not mocking" in his youtube video though... and in the same breath said that he does, however, mock at the boundaries. Which makes me wonder if this is all just a terminology confusion. Because for instance, if I'm testing a public method in business logic, I'm not going to mock the private methods that it calls in that same business logic layer - that just seems crazy to me. And yet I would still call that a unit test, since it's still limited to one layer, if not to one single-layer-of-abstraction method. I will mock the dao layer in those cases, though, because that strikes me as a completely separate layer/concern. But I don't know, maybe someone else would say that I "don't mock all that often".

> Torture is against international law.

True.

> Even if you want to quibble about whether Geneva Conventions apply to "unlawful combatants" I think that even non-treaty customary international law would forbid torture.

More importantly, it would be against treaty-based international law even if you ignored the Geneva Conventions completely, since it is prohibited by the Convention against Torture and Other Cruel, Inhuman or Degrading Treatment or Punishment.

Are you aware of something that can't?
I love the idea, but bootstrapping is the real tricky bit with a site like this.

Putting aside the grant funding idea, I think you could really democratize academic publishing by adding a StackExchange-like rating system to something like ArXiv, and also building in a conference organization system (this part is actually key). You'd allow researchers to link off-site (even paywalled) content to their profiles (email to the address listed in the author list should be sufficient authentication), and bootstrap the rating system by granting reputation points in certain subfields to authors with recent publications in reputable conferences/journals. You get reputation by people who already have it positively reviewing your papers. The system gets papers by including a really good conference organization system (in-person networking is still very worthwhile, even if we solve the journal problems of distribution and peer review), which requires conference submissions to be put into the system, along with the reviewers comments. You'd fund the thing (and weed out junk submissions) by imposing a relatively nominal fee (say $50) for lifetime hosting.

Such a system is technically possible, but it would need to achieve critical mass to actually replace the existing journal system.

(I should mention I'm coming at this from the perspective of a computer science researcher - in a lot of the subfields of CS the most expensive parts of doing research are 1) your time and 2) institutional library access to get at the papers you need (Google Scholar helps here, but it's far from perfect), so large grants are less essential than in disciplines that need expensive laboratory equipment or travel to exotic locations.)

This sort of reminds me of the rat control system the Canadian province of Alberta has in place[1]. Since Alberta is bordered on one side by the Rockies, you only need to control the Eastern plains to stop them from moving in. The "rat control zone" extends from the US border and up along the Saskatchewan border about half way.

Since Alberta grows a lot of wheat and other grains, there is value in limiting the presence of rats.

In addition to setting traps and poison along the rat control zone, they also have official rat control officers that search farms and shoot any rats they find. [2]

They have found a number of rats in recent years, so there is some doubt that Alberta has remained truly "rat free".[3]

As mentioned elsewhere, Objective-C is mostly dynamically typed, and you can just silently cast id to things, so it doesn't need generics as much as a language like Go, although they certainly could be useful. On the other hand, the dynamic typing makes it slow with generics or not, and if you want to put numbers in collections, you have to go through a very cumbersome boxing process - two of the many things only a new language could resolve.
I think it's safe to say that there's some sort of correlation, although of course obesity is a complex issue.

Higher caloric intake is just part of equation. Sedentary life style, increased stress, reduced sleep,
"western" diet (highly inflammatory, with poor nutrient density), craving-inducing food, and messed up intestinal flora are just some of the things that likely contribute to obesity.

As someone who travels from US to Europe often, I always wonder what exactly it is that causes such dramatic difference.

Is it gluten, that's been under scrutiny lately? It doesn't seem to be so, since so many European countries are happily eating their bread. Although European-favored sourdough has been shown to positively affect intestinal flora through fermentation, unlike those puffy bread-like impostors you see in commercial stores in US.

Lifestyle doesn't seem to differ much either, although Europeans definitely have a more sacred and slower approach to meals, and there's less of that "quick lunch in a rush" culture.

However, portion size and difference in cooking oils (olive in EU vs. corn/cottonseed/canola/etc. in US) seem to stand out the most, and are probably the biggest offenders. [1]

Of course your own hand-wavy numbers will support your argument, it doesn't mean they are correct, nor that your socioeconomic assumptions are correct. And the topic of this article has nothing to do with athletics or the shady academic policies thereof.

I never said these students were substandard. I do believe their performance is substandard and they are at greater risk of dropping out because of all the disadvantages they had and continue to have in life. I believe good schools should admit them because their potential is equal to the non-disadvantaged students, and the results in the article prove this. The article even points out that disadvantaged students with potential do better when admitted to the better school.

Your view does not separate performance from potential, and you keep insisting on using low performance to limit admissions to good schools, and thus in a way, limit how much potential these students can develop. You are essentially arguing that the poor and uneducated (who are likely to be minorities) should stay poor and uneducated.

I believe that it is a net gain for society when all students are given a chance to meet their highest potential. This article shows that he cost of doing so is minimal, and thus the gain for society is even greater.

Noting that on the before the "you're one step away" immediately jumps out at you.

Personally I don't like that it seems like overselling to me. I'd like an a/b test just with that one phrase actually.

The ideas presented sound good in general and make sense. I'd guess you'd have to tease out which of them actually did the trick.

Anyway, another possibility is that there was something negative on the sparse form (like the "you're one step away") and by adding a few things to the page it detracted from that.

In the same way that if you have a big nose it's less obvious if you do your hair (and makeup if a woman) in a certain way. So it's not the fact that you are adding makeup or hair as much as it is that the nose doesn't appear as big.
From what it looks like, the founders didn't submit it to HN. For all we know, this page was thrown together as somewhere they can direct people who ask them what they are working on, not somewhere they are actively trying to drum up interest with (if they had nothing beyond what the page shows, my guess is they would have gone with a Kickstarter, rather than just an email capture).
I'm guessing that it's a response to the whole "Swift is slower than Obj-C" thing from yesterday https://news.ycombinator.com/item?id=7849213 which did exactly this sort of comparison.

CO:CI is impossible to follow period. There is simply no way to measure accurately both ends. It might be useful as a tool to some people, but as an objective solution it's just a banal truism with no reproducible path to success.

Yep, it's certainly a risky project, but I'm psyched to be able to fund it. Ashwini's proposal included a well-reasoned review and validation plan. Even if it ends up not being successful, I think she's approaching things from the right angle, and I'll be very glad that she tried.

Honestly? No. That's just being a fresh grad from Princeton.

If you're in a position where you could easily go get a high paying job, but instead you choose to go on public assistance so you can focus on your startup, I'm not sure why I as a taxpayer should be subsidizing that.

Predictive typing for single words is usually based on a locally stored dictionary, and for sentences it can be done with a model like prediction by partial matching. The device functionality is similar to a system used for speech recognition, in that better accuracy would only be gained by sending motion and text data to the cloud at the very least in the training stage and then aggregate and analyse data using a prediction model.

However, no-one seems to care that most voice recognition tools like Siri nowadays send and store data on servers, and nearly all those aren't OSS.
As long as there was a metabolic pathway to reach it, absolutely.
