NYC is actually one of Uber's most important cities. Don't forget that NYC is more than just Manhattan below 125th street. Getting a taxi in the outer boroughs was miserable. The green ones help but were a little too late. The black car services are entirely unpredictable and unreliable, doubly so if you are not of the ethnicity of the dispatcher/drivers they employ.

And let's not even talk about the number of times a cab driver straight up refused to take me to Brooklyn, both during the day and late at night. Totally illegal, but it happens all the time.
Heck at least pull your principle out and ride the rest.
I actually don't because I can't. I won 1 btc at a small competition on r/Bitcoin (Hidden private key kinda game) last year and been trading with it, I spend the profits.
I don't see the problem:

- You are using "scamming" as a binary yes/no behavior, when in fact there is a huge difference between lying about a faulty machine and committing credit card fraud. The most likely reason for the lie (not "scam", that's too strong of a word here) is to avoid the credit processing fee. And that's _if_ they are lying in the first place. There simply isn't much (risk-adjusted) benefit for the driver to escalate that situation into credit fraud.

- The information on a hard-copy swipe is identical to a magnetic swipe and also the information provided to any online merchant (i.e. CC#, name, expiration; not CVV). Why should I be any more worried about this information on a piece of paper vs. the risk of a card skimmer at a gas station? Or a security breach of any one of the multitude of online retails who I have _ever_ shopped with?

- As you stated, the risk goes to the bank, as I am not liable for fraudulent transactions on my card. In fact, there's actually risk going to the driver as well: without an immediate approval, they don't know if I'm handing them a worthless card!

- The implication from your statement seems to be that... you wouldn't pay the driver, who has already rendered services and is capable of accepting valid payment from you. Is that what you mean? If so, that is not OK.

This is great analysis. Keeping in mind there's more motivation to do this kind of analysis during euphoria phase of the stock market than during capitulation phase of the stock market like in 2009 or 2010, I think this shows investing in the long term will cancel out losses in the short term.
Very very cool!

And it's about time someone did it! Yours is the first hobbyist project I've encountered since my own extremely crude ten-dollar version in 1981. No square array or processing, mine was a mechanical scanner-disk: eight LEDs glued in a spiral to an old vinyl record album, each with an electret microphone and and op amp. Spin the disk with a motor at about 6Hz. Wind noise, so add foam to the mics. It worked. A mechanical acoustic-phosphor raster sensor and display screen, where sound patterns caused light patterns. The best part was to hold some headphones near it while playing 10KHz sine wave. This produced interference stripes on the scanning disk! I hoped to build a huge version someday, but somebody beat me to it: Tom Zimmerman, an MIT student who patented the dataglove, then used the money to work at Exploratorium Museum for a year (as Artist in Residence), building a scanning-microphone LED disk about 6ft wide.

Since then we have companies selling DIDSON full-blown video for underwater (with sonic illumination,) also a euro company with a 3D phase-array microphone imager positioned on a ring or a wire sphere. See:

moving my brilliant comment from dup thread: Really gets to the nature of what we mean by the term "intellgence". It's _gender_ specific. A lot of times in AI you'll hear people talk about a no gender robot thinking for itself. But we have no examples of genderless intellegent humans. intellgence implies gender.

Futureshock was a book I picked out of a box of books put out to the trash one day a bit more than 10 years ago. I read it and was amazed at the accuracy. And just now when I read he died I thought to maybe read it again and the blue color of the cover is strongly still in my mind.
Oh, that makes sense. Do you have any reference for it? I found this explanation http://www.investopedia.com/ask/answers/040215/what-does-sp-..., but it doesn't seem all that trustworthy, and it seems to suggest that S&P doesn't account for survivor bias.
Neither are Ponzi schemes, neither FB, nor the DAO use income derived from the sale of securities to drive the payment of dividends on those securities.

Zuck doesn't control the majority of shares, he controls the majority of voting shares. If FB started selling shares and using the proceeds of those shares to pay dividends to existing investors then it might be a Ponzi scheme if this were not disclosed in relevant documents.

FEMA Contractor Predicts 'Social Unrest' Caused by 395% Food Price Spikes
Your comment amused me a bit, so I wanted to write something in response. I work in metal fabrication, our workshop specialises in structural steel, so we are part of the general construction industry. We call ourselves 'boilermakers', though I've never worked on a boiler.

Anyway, in the 17 years I've been doing this on and off, I have met precisely 1 female boilermaker. And nobody cares.

What I don't follow is why is gender imbalance in other industries seen as a problem but we never see any serious attempt to get more women in to the construction industry.

Why does anyone care there are differences in numbers of men and women in various industries? Things change over time, fashions change. I think approaching these issues from the "we must correct this imbalance" is incorrect reasoning.

And, lastly, if we do manage to level the playing field, what will gender identity become?

A quote form the film Trainspotting: One thousand years from now, there will be no guys and no girls, just wankers.

I'm willing to posit that strong gender roll identity is crucial for a healthy and resilient culture.

At age 22, you make 25k and get 0% matching, and can afford 0 to put into your still-hypothetical retirement fund.

Agreed. Not just "cool" thing done, but the tenacity, the work ethic, the constant probing.

I'm sorry I caricatured your position.

I think we agree that the assumption that "removing interviewer/managerial bias will result in a gender ratio of 50%" is false. The variability of sex differences in vocational interests probably accounts for more of the gap than bias in the hiring process, i.e. "mean old white men". I can also accept that physiology influences cognition, although where we disagree is how much of a factor that is in the gender gap, or how relevant it is to any sort of policy decision.

Removing bias in the hiring process wont solve the gender gap entirely, but it will help it.

Telling girls that they can do and be whatever they want wont solve the gender gap entirely, but it will help it.

Changing the masculine and sexist culture in STEM wont completely solve the issue either.

There is basically nothing that can remove the hypothetical physiological factors contributing to gender disparity in STEM fields. So why are we even talking about it? It derails the conversation. There are things that can be done, and we should do them. Until we reach the limit of what is possible according to your hypothetical physiological explanation, why bother even bringing it up?

I'd be kind of surprised if mutual funds were doing much investing in this kind of ETF. Look at the shares outstanding of FXE, FXA, FXB (currency etfs for euro, australian dollar and pound), they're not very popular. Some hedge funds do use these and famously Paulson was using GLD for his gold exposure (I still think this is pretty dumb, he should've traded futures and EFP-ed into spot gold). Wouldn't be shocked to be proven wrong, but most ETFs don't gain traction. There's also a pretty small cap on how big this ETF can get (at least for now), almost by definition the commodity backing a bitcoin etf has a much much smaller availability than the commodity backing any other etf. I am glad they're using cold storage to store them at least.

Comments on this thread are not very interesting and generally off topic. This article points out an issue in SV which is that it's hard for employees to get value out of options held in companies that do not go public.

One reason for this not mentioned in the article is that in the US the tax burden is extreme - partially because when it was implemented it expected companies to go public.

If you hold options in a private company you get taxed on the exercise of those options based on the fair market spread which is the difference in price between your original strike price (the price of the options when they were granted to you) and the current fair market valuation. This is taxed as income.

This is problematic since once exercised you're holding shares of an illiquid asset (since the company is not public) and they're difficult to sell. This means even if you save up enough money to exercise your options you'll get hit with a potentially enormous tax bill due that year that you can't easily sell your newly exercised options to pay for. Additionally when you sell the actual shares after you've exercised them you get taxed again on the sale.

The one exception to this is if your options are ISOs (incentive stock options) then the delta between the strike price and the fair market value isn't taxed immediately, but it does count towards AMT (Alternative Minimum Tax) and it's fairly easy to hit the AMT while exercising options (meaning you could only exercise a tiny amount per year tax free).

All of these things make it extremely difficult to realize any value in a private company without enormous amounts of upfront cash and also losing roughly half to taxes. It also makes it extremely difficult to exercise options outside of a liquidity event. This can also make it hard to leave a company since the agreements are often 90 days to exercise after leaving or you lose your options (there's also usually a ten year expiration date).

If companies in SV intend to stay private and don't want their employees to view the options as impossible to liquidate we'll probably see an uptick in liquidity events like this one. The companies that value their employees will probably figure out a way to make this work.

The reason the author's beamformer doesn't work very well may have nothing whatsoever to do with his implementation. A short-baseline microphone array won't be able to have good selectivity in the human hearing range no matter what you do. All synthetic aperture systems are fundamentally limited by the wavelength of the thing being sampled. You need an aperture many wavelengths wide in order to get a significant effect at any given frequency. The tiny two-mic device shown in the picture will only be an effective aperture in the near-ultrasonic range.

That's why commercially available phased array microphone systems that actually work are typically one to several meters wide.

I more tend to consider his works overrated in that he successfully "prevented" the "terrifying" future of never-ending, ever-accelerating change he foretold by managing to make sure that very little at all was allowed to change.

Call it a generational difference and also disrespect for the deceased, but being a child of the late '80s who grew up with Gingrich a major figure and "future shock" a commonplace concept, I've reached the 2010s and managed not to be future-shocked because people keep acting on their "future" shock by keeping things largely the same.

Worse, the social problems he was preaching about happened despite the lack of flying cars and techno-singularities, because it turned out they were largely about underlying slow shifts in social conditions anyway rather than about the shock of an ever-accelerating technological change that never happened.
The mining algo has nothing to do with it. As soon as the hard-forked clients get to the block on the non-forked chain where the hard-fork causes it to be rejected, it will reject the whole chain. It doesn't matter how long the chain is or how much work was applied, if the rules don't allow for the block it's rejected (and therefore the whole chain).

It looks too serious and isn't necessarily immediately recognizable as parody and is harmful to the NRA's trademarks.

well, everything I saw was right out there in the public record.

so, again, I'm more comfortable letting others reach their own conclusions, connecting the dots, taking action. I think whenever we deal with anonymity-enabling cryptocurrency systems, and distributed actors, the web, you need to find your own balance between not being too gullible at one extreme, versus, not being too paranoid or prone to mob justice or witch hunts on the other. if I were 100% certain I know what happened, I'd say it. but I'm not 100% certain, therefore I won't.

similar to my thoughts on Mt Gox a few years ago. we may never know the exact truth of what happened. but if you see certain definite facts, on the surface, a certain pattern, you can reach your own conclusions about what was hidden below the surface, and make future bets accordingly.

I'm a little unclear on this whole thing, but I believe that Ethereum and The DAO are distinct things. Ethereum is a virtual currency, and The DAO is something built on top of that virtual currency.

So the situation here is not so much like founder investing in his own creation, but rather like a founder investing in a user of his creation. Then the user screws up, and some want the founder to make a change in his creation to help that user...but that change might hurt other users who did not screw up.
