Assuming they eventually win all the legal battles and drive all other taxi and taxi-like services out of business

That's very unlikely to happen and I don't think anyone here at Uber sees the world as a zero-sum game as you portray it. Even in SF, the most mature Uber market, there are still plenty of cabs operating. Cabs offer a different service (street hails, fixed pricing etc) - which is why you can even hail a cab from the Uber app if you want.

Differentiation is key, and that's how Uber does and will compete with both taxis and direct TNC competitors.
I think (not an economist) but this is what happens when a market is disrupted, new players enter with a lower cost than incumbents, clean up, this encourages other new players to enter at slightly below, first player then drops to match and eventually you reach a new stable equilibrium, in lots of markets that is by one company winning and buying out the others (commodities like Sugar and Salt seem to go this way, it's hard to differentiate on Salt) while others divide up amongst big players (laptop market).

Uber will be interesting since the initial capital costs aren't that high (compared to a multibillion dollar fab plant or hundreds of 40,000sqft shops) so it could be a blood bath, alternatively one way of differentiating is on brand and Uber has (despite some negative press) got brand recognition.

There maybe a first mover advantage in play here as well, lots of sites clone successful sites (for example) but rarely make a tiny fraction of what the original one did.

Something else occurs, Uber took a lot of VC funding, new players entering the market who didn't do that could offer a better deal on both sides of the market and not have the millstone around their necks either, it would be amusing if a smaller nimbler non-VC company ate their lunch.
I completely agree - I have no problem with leveraging low-level functionality, but there's usually a safe and and unsafe way to approach it - and from what I've read 'unsafe' doesn't take the secure approach.

(separately: why the downvote? I get downvoted for having the opinion that it's worth a tiny bit of performance for improved security?)
I used to care about owning my music, but over time the money just kept adding up and so did the inconveniences. Want this artist's albums on my phone? Dammit, gotta take time and copy all that over. New music? Welp, there goes my food for the month (I don't like pirating). I made a new playlist on my computer, and I want it on my phone? Dang it, it didn't find the tracks that I copied on there before and so it's useless.

Paying $10 a month for a streaming service (I use Google Music) made a lot more sense to me for than paying $30-$100 a month buying albums.
After you're inside and the door is closed.

This is the only way you can get to the airport during the "shift change" that's right around PM rush hour. Nobody will take you there if you tell them you want to go there.

That said the new Q70 bus from Jackson Heights (7/E/F/M/R) is quite efficient, and I don't bother with cabs anymore. Not worth paying someone $40 to bitch and moan about going to the airport when the MTA can get you there, from Brooklyn, in less than an hour for $2.50.
Not that i'm the proshit haskell expert, but I don't think that GHC does the most amazing job in applying optimizations and I definitely think its performance paradigm is really hard to reason about.

Still, it was a nice breakdown of a real non-toy problem in haskell!
Cache hits vs subsetting FA only is probably a wash overall. I don't have numbers for that specifically, but that's my strong hunch.

As soon as you want to add your logo or use a different icon set, it's worth it. I think Fonticons is more important if you're looking for something a bit different, style-wise.

(We're dogfooding Fonticons on Fonticons. And we had a lot of fun with some of our error pages: https://fonticons.com/404.html, https://fonticons.com/500.html, https://fonticons.com/503.html. Copy and pasting icons out of Illustrator makes it super fast.)
I think they need to offer a 365 day 100% money back guarantee if not satisfied for any reason.

Then the buyer takes less risk, the seller still knows they are a 'real buyer' not a freebee seeker because pulling out the credit card is still a commitment, even if you decide to get a refund later.

I also don’t think it is very likely either, I was just assuming the best case scenario for Uber and I can’t see how they can make money in the long term even if they achieve this. Competition is great for consumers, but not so good for investors.

Edit. Thanks for the updates to your post Ben. Given Uber’s cost of capital and current valuation how do you see Uber earning enough of a return with a differentiation business model? Or is the current business model irrelevant to Uber’s future and you foresee a massive pivot?

We’re now excited to announce the next stage of our journey — we’re joining Dropbox!

[ Dropbox will build on their technology. ]

The Clementine service however, will be shutting down. The free portions of the app will remain active for current users until August 31, 2015 and we’ll provide plenty of help to regular and premium subscribers as the service transitions.

Remind us again why we should take a chance on startups like this??? I wish more people would realize the potential for a vicious cycle.

Side note: 5 weeks in the dog days of summer isn't much time to transition; I hope it's longer for paid customers.

"And this is a key advantage: When basic needs are met, it’s easier to be creative;"

If you are so poor that you can't even eat, of course you are only focusing on survival and can't be creative. But I have been the most creative when I have just enough to survive (to keep me hungry), but not much beyond that.

"If one does not have money in the form of a family with money, the chances of becoming an entrepreneur drop quite a bit,"

I know they are equating it to money, but I also wonder if it has to do with financial education taught by the parents. Many parents most likely pass their poor financial advice (or no advice) onto their kids.

A good example is getting a credit card with a 22% interest rate at 18.
Some applications use binoculars to indicate search. Yet that could easily me mistaken for zoom, though...

Iconifying things is hard.
In the last few years NYC has closed stretches of Broadway (a significant north-south corridor) to traffic, squeezed vehicle lane widths to add bike lanes and introduced several measures to slow or impede traffic so the city is safer for pedestrians. These are all very good things, but they come with a cost.

Reducing the surface area of roads does not magically remove cars from the roads, it just creates congestion and traffic.

If anything, Uber's model would seem to reduce traffic since their cars are more deliberate vs. taxis' aimlessly wandering.

NYC should try to figure out how to partner with Uber. Taxi's are already expensive enough to be something of a luxury (though filthy), Uber is a far better experience.

There's a school of thought that argues that it didn't work for Gandhi, or MLK for that matter. That both of those "non-violent" leaders' words and actions were backed by the everpresent threat of violence. These include obvious threats like Malcom X and less obvious ones like the potential for a large group of people to simply devolve into violence when provoked.

Indeed, one could possibly argue that encouraging non-violence is beneficial to the state because it effectivly reduces the threat to the state and makes alternate views easier to ignore.

I personally think it's more complicated than either view, but it's worth considering that in a larger context, non-violence rarely means non-coercive.
Just FYI, previewing icons from the premium set on mobile shows a bootstrap dialog that has all manner of layout issues: too large and wide and icons are too small. Not the best way to showcase the great work.

If urbanization makes people depressed and anxious, why do millennials seem to prefer cities? How does this jive with the "safety in numbers" feeling young people usually use to explain why they want to live in cities?

I'm starting to think that the desire to live in cities in our newest generation has been implanted by marketers. Keep humans in a constant state of rushing and anxiety, then quell them with gastropubs and single-origin coffee and other urbane pleasures, in order reinforce a permanent state of discontent. The goal is to have an insatiable working class that will do anything to afford their $1,500/month Brooklyn closet, without realizing that you can be much happier and more relaxed anywhere else.
The Man Who Found the Man Who Broke the Music Business
on OS X, any application that you would normally open as a side effect (opening a document, for example) will close if there is no reason for them to be open anymore. This includes pages, textedit, keynote, preview, etc. They do this because there is no reason for them to remain running if the document is closed. Typically, if you launch the application by itself and it asks you to open a document - these applications will close themselves.

On the other hand, applications that don't need to open a document to run, or don't open as a side effect of opening a file, will remain running if the active window is closed. This includes mail, messages, finder. The user benefits from these applications running after the user has closed the active window, since the user might want to launch them again quickly.

Not at all equivalent, because code isn't meant to be human readable, but computer interpretable. Because of these different goals, computer code is actually quite a bit harder to read than a well structured academic paper. I think programmers have a lot to learn about logical structure from writing meant to be read by humans [1].

Note how many people on this thread seem to be understanding and discussion its contents, whereas if I were to post 13 pages of "unfamiliar, complicated code" that claimed to do something, I can't imagine anyone would help me debug it.

I don't think estimating will be that much of a problem if the right formula is used. Is this straightforward and the team a has done stuff like this before (most cases)... apply the component formula and add the markup. Is it hairy with lots of unknowns? 1.2 million dollars.
of course, I agree, I wasn't critical of your post. I just found it amusing that you think you have zero business acumen. Apparently, those who downvoted me have no sense of humor :)
Unfortunately, all of those mitigation techniques have problems of their own. (Not to mention that you glossed right over the politics.)

With AC power, bigger grids can create instabilities. Look at the 2005 Java–Bali blackout, for instance. Cascading failure. Or the Northeast blackout. Cascading failure. Etc.(With DC power, you have the same thing, but to a lesser extent. Among other things, you need less failsafes for DC than with AC, and it's easier to bootstrap the grid.) You can avoid this by... making grids less interdependent. Which you cannot do if you're tying them together for purposes of keeping them running. (And smart grids mean that things go wrong more badly when they do go bad.)

Lots of wind turbines geographically distributed would be great - except, of course, that wind power isn't available everywhere. Remember, the power carried by wind scales roughly as the cube of the windspeed. There's a relatively small window of "enough, but not too much" where wind power makes sense.

Ditto - pumped hydro I talked about, but again, you have to have a watershed with enough capacity. Which isn't the case everywhere.

Demand management... Good luck with that. That's politics, as much as anything. We have come to expect reliable power, and trying to convince people otherwise is an uphill battle, as it is very much a regression.

And as for small-scale gas-burning plants... Two things. First, by the time you've added up the wind turbines (again, wind turbines are hideous for the environment to make!), the additional infrastructure required to be able to inject power safely at distributed points, the additional infrastructure for a smart grid, and the gas-burning plants, things look much less obvious. And secondly, gas-burning plants are either inefficient or don't scale fast enough to be worth it.

Oh, and they are expensive. It may be better to sink the absurd amounts of money that is required for wind (especially when you realize that gas-burning plants are really expensive for their energy output) elsewhere.
Absolutely correct, yes, the authentication process needs to be handled outside the app.

While it's possible to have a login stored proc, this is not strictly necessary. If you have e.g. an OAuth2 server which is separate from your application, you can use those tokens for authentication with your database.

If the application is completely compromised (e.g. someone has root on server), then a malicious party would be able to act as any logged in user by dumping tokens.

However, what they would not be able to do is arbitrarily dump your database, bypass your auditing, or mess up your application invariants.
I'd probably just give a 60-day money-back guarantee seeing as 1.0 is set for release around October. By then, if the features you're regularly using aren't ironed out it'd make sense to refund.
I think you under-estimate the power of network effects and also the cost of entry to set up an on-demand transportation company. If it really was as easy and low cost as you assert I would suggest you would have seen many other players enter the market already by now.
Flaws in trials of deworming pills show the importance of sharing data
Regarding the hamburger icon, I suspect most people have seen it many places and recognize that it can be clicked/tapped, but they interpret it as "here be dragons" which is why it always scores so low on A/B testing. Even knowing what it's just an innocuous menu, I rarely sneak a peek at what might be lurking there unless the function I'm seeking isn't to be found anywhere else.
It is rare to see, of not impossible, a real monopoly in a free market.
Uber has to compete to win customers, if they artificially raise their prices to where people will not pay, people will choose a different form of transportation.

Gmail and Google Voice compromise  any ideas?
Last night I got an email stating that someone had gone through the process to recover my user name from my phone carrier. I have a family plan and multiple people pay, so I didn't think much of it. I should have.

This morning I noticed first thing in my gmail inbox was an email stating my long defunct google voice account had been reactivated and had been forwarded to a new number only revealed as --28. Literally within minutes of noticing that email I get dumped from my google session on my phone and find my password has been changed "Within the last hour" according to the google recovery process.

Meanwhile on my phone, I started getting texts for account password reset procedures for paypal, ebay, etc, etc. At this point I realized he was getting my text messages. Fortunately I was able to make enough phone calls to get the critical stuff under control.

If that wasn't enough I start getting text messages from the number that the google voice had been forwarded to. This time though I get the full number 215-798-0328.

To which I received;

12:20 PM Hey
12:21 PM 10 BTC for your shit back and we go separate ways
12:46 PM Or do I post your nudes on your FB
01:26 PM Im closing all your accs perm

I looked up the number and found that its carrier is registered as bandwidth.com

Ugh ... to say the least.

So here is the conundrum. I wasn't using google authenticator (big mistake it seems). However the attacker has control of my gmail and google voice (essentially my phone). There are no contact numbers for either google voice or gmail.

I did contact my phone carrier and had them forcefully remove google voice from my account. I did the long recovery procedure for my gmail account which apparently takes 3-5 days.

Has this happened to anyone before. What do you do? Should I report this guy? I mean kids will be kids ... but a ransom? Thats pretty over the line.

It also has a lot to do with the rate at which you took to get to that "death zone". If it takes three years to get to $50k/mth, there will be big question marks around your ability to scale beyond that.

It's not a coincidence that this zone maps up with the "chasm" between niche and mass-market appeal. If a company has been unable to already demonstrate that they can scale the product effectively, they're asking a VC to take a punt on whether they can or can't...and if it's taken 3 years, then evidence already suggests that perhaps they can't.

The other problem, is that after 3 years whilst it still may not be clear what you're company could be, it's already known what you're _not_. The possible outcomes have been narrowed. It's known you're not going to be a complete failure, but it's also known that you're not a "Unicorn".

When more bandwidth gets deployed someone will roll out more bandwidth-consuming video.

From what you've said, it sounds like SF and the Bay Area may be more of an exception than the rule for the US as a whole. My only experience with it is one trip to Santa Clara, so SF is not what I'm basing my opinion on. Most suburbs that are not immediately outside of a major city are probably what you'd consider pretty podunk.

I've lived in places that really ran the gamut from middle-of-nowhere bible belt where we shared a party line with the few other trailers, podunk suburbs, to a small city, to NYC.

I don't do night-life, and I know a number of other people that don't really do the club/nightlife thing either. So maybe the whole find the beat of your drum/chaos/excitement thing is more referring to that. I have a pretty quiet, boring life in the big city and I love it. I'm a short walk away from a great greenmarket, tons of parks, a great bookstore, tons of good food, coffee, beer, etc., etc. And I never have to drive or sit in traffic.
What profits? Uber is losing money every day aiming to provide a quality service for people. They lost tens of millions on last years numbers.
Will most likely do the same this year as well.
Industries like sugar and salt are commodity industries where prices are driven by costs. There are economies of scale that allow one player to dominate a market and prevent new entrants. Uber does not have this advantage since each market is effectively small and isolated (there are thousands of taxi markets in the USA alone) and most of the costs are unit costs, not fixed costs over which they can scale.

Any competitor with lower costs - say a business that used only one fuel-efficient car type that offered lower unit costs should be able to outcompete Uber. The contractor model where each contractor purchases and services the needed physical equipment (i.e. cars) is far from the most efficient way to run a capital intensive business.

Sure, but their investors are going to want them to start extracting profits at some point in the future. You can’t run an business indefinitely selling below your costs. The question I have is how are they going to be able to start doing this without opening themselves up to competition?
I've never seen a company that sanely implement their filters. How do they do that?

Unless you consider it sane to block anything that is not http.

But, well, the idea of filtering bad things from the internet is insane enough by itself.
