I've read a pretty lucid (for a change) analysis of this over at /r/bitcoinmarkets

The gist of it was that BTCChina's long game was to kill all competition (by being first, and zero fees), wait for the surge of new users to taper off (market saturation?), and start charging a fee once they've monopolized the market.

The OP further speculated that they must've interpreted the change of regulatory climate as disastrous, expect a major exodus, and have implemented trading fees to get at least some profit off the activity.
Not complete bs- Some limitations on third party payment services are real, though perhaps only minor inconveniences.
Maybe this already exists, bit I see a startup opportunity for tagging a study as "of interest" and having a site build a portfolio of information related to that study and finding new studies. Feedback could be given on the relevance of returned results.

Something like the app flipboard but have it contain dedicated magazines/journals that gather up and continually build out.

But cold caches are an unrealistic assumption. The top-most levels of a tree will always be in cache, unless you almost never access them -- in which case there's no problem either. Additionally, a radix tree is ordered, whereas a hash table is not.
> Asking the Virgin Mary to pray on your behalf in Catholicism is whitelisted, therefore according to Catholics it is not witchcraft at all. According to tackless hardline protestants, it is not whitelisted, therefore they label it as what it really is, a form of divination.

Er, its not divination in any case, and that isn't what hardline Protestants call it. The issue some Protestants have with intercessory prayer isn't that it is "divination" but that it is, as they see it, inconsistent with monotheism (incidentally, this is the same problem that, e.g., many Muslims have with Christian trinitarianism.)

> Furthermore, your definition of divination is steeped in Christian bias.

Its what the word means. Whether or not that fact is a result of a history of Christian bias is, really, beside the point; if you want a generalized term for superstition modern English has one; abusing a term with a different and clear definition for that purpose just obstructs communication.

One of the Ridejoy cofounders here. Thanks for sharing your positive experiences with ridesharing. It is because of people like you that we believed so strongly in Ridejoy.

If you were willing to put up with all these hurdles of lack of any real search mechanism (some posts say "driving 9/17" and others "next Thursday"), a totally unstructured multi-step posting experience and no form of reputation or review or payment, in order share rides, then if we eliminated those hurdles for others (you might not seem them as hurdles, but other people definitely do) that we could expand the market for rideshare many fold.

We've spoken to many people who've shared rides and sketchy experiences do come up from time to time. An app cannot eliminate that completely but it can help alleviate it and kick out offenders. I believe that the system has lots of opportunity to improve and I'm sorry you don't think we were helping.
Are you implying that Uber has no impact on the shape and nature of the market of taxi cabs and drivers in the cities they serve?

Because that seems pretty hard to swallow given how much people crow about Uber disrupting markets.

Uber does help define the landscape of drivers and availability. There are other sorts of pricing models they could even follow. Why not charge a little bit more during off peak times, and then turn around and incentivize drivers using the subsidy from off-peak hours, rather than dumping it all on individuals traveling during points of tumult/crisis?

There are a lot of models between the awful medallion system many cities have and the way that Uber works right now. And frankly as much as i hate how taxis work in a lot of US cities, and as much as i love the user experience that Uber delivers, they certainly should not be immune to criticism, especially over issues like this.

Node.js News Round-up – December 17, 2013
Over the summer I extended a lot of weekends with a days holiday and so ended up working a lot of 4 day weeks.

Surprisingly, I found that my productivity really didn't drop that much. I went into a week with a sense that I only had 4 days to get stuff done, and so often felt much more focused. It's only an extra day, but somehow in my head a 5 day week feels almost endless. The suddenly it's Friday and you wonder what happened...
Roads are free to use which is a ridiculously huge subsidy. Also, driving is a lot more expensive than you might think it just involves a lot of sunk costs which people ignore.

EX: Driving a cheap car 15,000 miles per year with 3$ gas 30mpg = 1,500$. Except insurance is ~90$ a month which adds 1,080$ a year. A combination of maintenance / car payments / depreciation runs around 200$ a month adding 2,400$ a year. Live in town that's generally 100$ a month (12,00$/year) for parking at your apartment which is generally close to break-even for an apartment complex. Ignoring other fees like tolls etc your talking about 6,180$ a year for 15,000 miles or 41.2 cents a mile which is far from cheap.

I'm not so sure.

I took the fated Trenhotel Joan Miró that the author talks about. It was a little over 100€ and covered the distance in twelve hours, like the author said. After getting off that train, economically I could not fathom why anybody would ever subject themselves to that experience again.

The 100€ got me a seat in the back of the train in a semi-reclined seat (the least expensive ticket I could buy). I booked it about four weeks in advance. For 150€, I could get an actual bed to sleep in (four to a compartment), and the price/service level went up from there. If the train had free food or even just free water, Wi-Fi, showers, and such like you describe (at least at that price level), it'd potentially be a different experience. But Trenhotel's stock is about as old as it gets, and what you get for the base price of 100€ makes for quite an unfortunate twelve hours.

I just went to Vueling, and I can fly from Barcelona to Paris for 40€ in two hours. Even with security, time to/from the airport and such, I'm still saving time and money. Copious amounts of baggage is the only thing left out, but I could pay 100€ to check piles and piles of bags, and now I spend slightly more than the Trenhotel and arrive five times faster.

High speed trains make sense for semi-long distances. Paris to Amsterdam is a great example. Three hours on modern equipment is very doable, and a plane ride can't beat that in time (fixed costs of security and required early arrival are too high). Comfort is superior, and the price will come down. The author makes the point that the cost is 2x but the travel time is only slightly faster. These routes were just inaugurated, and the stock is fresh out of the factory. Give it a few years, and they will come down. I'll bet you the old "vintage" routes that the author pines over were pretty darn expensive when they too were first inaugurated.

For the <4 hour trips, high speed rail is excellent, and I believe those prices will fall. But anything longer than that, forget the night trains. They're only semi-useful for tourists and backpackers, and I'm shocked they still operate. I'll fly, thanks.
I've done pair programming extensively, both for personal projects and at work. Pair-programming sessions are not the time to process email; IMs/IRC are treated as interrupts (quickly check if an urgent response is needed and otherwise defer); meetings are something you schedule pair-programming sessions around; deployments are a great thing to do as a pair to reduce screwups.
I know the basic laws of supply and demand. that is EXACTLY what I mean by dogmatic. you're quoting textbook theory at me as if the doctrine is self proving and as if I'm some sort of idiot for questioning whether your textbook doctrine applies in real life situations.

I'm asking you to consider whether or not your abstract economic theory is really operating as you expect it to in this situation. this is the real world we're talking about. its not a free market. its not a toy example in a text book. between naturally occurring inefficiencies, legal interventions, and unforeseen outside forces it is highly doubtful that basic supply/demand price effects can be thought to apply reliably as the textbook describes.
TED talks are marketing.
There is no real link between most of these talks so the fact that it is a TED talk rather than just a presentation, is basically meaningless. TED is just a brand that people licence in order to attract an audience. Over time, with no quality control on the talks other than charisma, it is not surprising that TED attracts all manner of charlatans, liars and conmen.

It is a shame really, because some people who present at TED have really useful and important things to say. Perhaps we will see a startup enter the space to comp.ete with TED and as part of their business model they will checkout the speakers and the content of their talks, only approving the ones that are not charlatans. Seems to me that this is the key problem to be solved, not just creating another brand umbrella for public lectures.

Getting accross town and getting into a terminal also adds a sort of stealth time tax (like an airport, but sketchier). The Jitney benefits from this heading east also, it seems.
At least in NY, there is no way in hell that Uber is going to put yellow cabs out of business. Not that yellow cabs are some kind of egalitarian paradise. They all congregate in the areas of Manhattan where the richest people live, work, and play. Good luck finding a yellow cab in e.g. East New York.

I worked with the author at last_job and can attest to the genuineness of his tone. Pairing is pretty fun when you like your coworkers.
Yes, I did not like the way they were doing things. No, I don't think leaving it up to CL is the solution. I had a guy once screaming very badly at me for being 10 min late, this kind of people cannot be spotted easily, you need some kind of review system.

Also, regular travelers can't organize well on CL. What's, say, 10-15 dollars a year to get a decent platform? Yet, I know, nobody wants to pay for that, chicken and egg, etc., but the market is there, of course it's there, people are moving all the time...
Capitalism and nature are two completely separate things. One is a man made system. The other is a system that made man. We have the power to control our own systems and we have been doing so for millennia. We don't have the power to control nature, it still controls us.

The problem arises when Über and Lyft have their way and bring about an end to public transportation but refuse to have any outside regulation.

The article is about more than Uber, the article is about how a whole generation of tech entrepreneurs seem to have almost no understanding of why we have regulated markets in the first place.

> But if Uber puts heavily regulated cab companies out of business, the alternative disappears.

Then we're into antitrust territory, which is a totally different can of worms.

> Would you be in favor of stores selling water for $100 a bottle before a hurricane?

If this were to happen, it means that there was not enough water in the first place. What's the alternative? Allocate to whoever shows up in line first? Then people who don't want to risk waiting pays someone in the front of the line to buy them a bottle of non-subsidized water, and the price of water hits $100 anyway - it just goes to someone else. As an example of how this works, see ticket sales to high-demand events (Super Bowl, concerts, and the like).

As an example of one strategy that works, one of the most important aspects of US Food policy is that we subsidize production so that food produced far beyond what would otherwise be the market-clearing price. This means that we don't have food shortages in times of disaster. One transportation-equivalent would be building a decent public transit system capable of mass evacuation.

Can you recommend any book or instructional movie that analyzes good (or bad) storytelling in film?
No, the contract is "considered", as the authors get peer reviewed and published by a big brand name and the publisher gets to charge the readers - everybody gains something valuable.

What you refer to as "contract terms" are mostly part of copyright law and nothing to do with this specific contract, for example the copyright holder has "the exclusive right to produce copies or reproductions of the work and to sell those copies" under copyright law which means that it is quite natural to transfer that exclusive right to a publisher thus preventing the author from making their own public copies. There is usually a contract term permitting authors to engage in ad-hoc sharing with colleagues for this reason. Likewise there is usually a contract term allowing authors to post their work to public-facing institutional/departmental web servers. (The original article linked to doesn't specify exactly what material was posted, I would speculate that somebody posted a bibliography or some other collection of papers in which they are not an author, and that is why the publisher is unhappy).

The publisher unquestionably delivers value to the author, their academic career rests on the value embodied in their peer review process and a typical article costs over $1000 to publish. There's certainly a conversation to be had about Elsevier and their policies but it does not include the phrase "Elsevier doesn't give the author anything", which defies logic.
>If we were really so good at pinpointing cause and effect in the markets, the people doing so would shut up and make money.

It's far easier to find causes than to predict details. For example, you know the numbers on some companies are going to be released at exactly 2:00pm, and then at 2:00pm related stocks move twice as much as they had in the previous week. You can't profit off of "80% chance of moving strongly up or down at this specific time", but you can make highly accurate claims about causes.
There's probably not much to look at, aside from pictures of bbq chicken.
Ok, fine then :) I admit I've never met anyone so genuinely enthusiastic about pair programming, so it sounds unusual to me.

It's not really Uber's dilemma. They warn people about the multiplier before accepting an order from them.

This is a simple case of buyers not wanting to take responsibility for their own actions.
I will further this a bit: there is a lag in new entrants that varies based on the industry (e.g. CapEx intensive industries need more time to ramp production). This clearly makes the case above (bottled water in disaster areas) even more of a red herring. Sometimes even the Red Cross has immense logistical trouble delivering supplies to catastrophe stricken areas. Obviously there is some need for humanitarian aid in the world (even in a purely free market society)

General microeconomics holds that markets where suppliers are earning excess profit will be targeted by new market entrants for a piece of that action. You see that happen everyday. Dollar menus at fast food restaurants, pizza specials between dominos/papa johns/pizza hut, Lyft/Uber/Taxis, Andriod/iPhones, Kindle Fire/iPads, Amazon vs every supplier known to mankind, etc

There are literally millions of real world examples of new market entrants seeking to cut costs for a increased share of a market.

Amazon does this 2.5 million times a day apparently (source: http://qz.com/157828/amazon-changes-its-prices-more-than-2-5...)
Just for the record:

- I've been using Fedora (VM, test, production server) since release 4 or 5.
- I have a VM that has been updated without full reinstall since release 11. It will be destroyed soon, as I'm reinstalling the host.
- I've been using Fedora as my main desktop since Fedora 16.

My experience varies, depending on the sh*t they decide to push (like Gnome 3 or systemd). It takes time so that things get stable (or I get more used to them).

As a full stack developer, I almost never use distro packages like gems or python libs or java libs. Even tools like Eclipse I prefer to install them separated.

Overall, I'm satisfied.

Price-gouging serves a purpose: it ensures that the service in question is not unevenly distributed to the first customer there. In situations like transit this advantage isn't as obvious as in situations like a gas shortage. Are cabs in the Bay Area regulated in terms of max prices? I end up avoiding Uber in surge times because basically every other option is cheaper.
