That link doesn't claim what you claim it claims. It talks about impact, and excludes a large chunk of the population for different reasons that it doesn't go into great lengths to justify (see page 597 (6 on the PDF)).

Also the definition that they use for povery is extremely literal, see here for more info on that:

https://en.wikipedia.org/wiki/Poverty_in_the_United_States#M...

Even with their massive amount of exclusions it still impacts almost 10%.

>> There are people who can barely afford to put food on the table
> Poor people are typically fat.

That's an incredibly ignorant thing to say. It is like responding to global warming by saying "it is snowing outside!"

Obesity is a side-effect of poverty. One person being obese doesn't exclude another from starving.

> The typical poor person has no job, if he does have a job it isn't minimum wage, and he has a car. He would also be healthier if he put less food on the table.

That's just raw bigotry now. You have given up the pretence even, you just hate poor people.

> Why do you keep discussing these completely atypical poor people, and extremely uncommon rental contracts?

They aren't atypical, they're extremely typical. Even according to your own link they make up around 10%. According to less exclusionary sources they make up more.
I think that's actually more optimal. After lunch I'm usually brain dead for around one hour or so and I don't really get much done.

Yeah, I haven't really had any issues with it over the last year. I don't always browse with vimporator but it's nice to have the option to follow a link, go back a page or scroll up and down without a mouse. It really depends on the workflow I'm in.

Until my daughter was born, I wanted to do everything without a mouse and I worked hard on that. But then I started getting annoyed that I needed both hands to work the machine. Now I have both workflows down pretty well and with my WM I can do most things with either.
Hi, I’m Kevin Murphy, one of the researchers at Google who worked on this project. Just to be clear, KV did NOT involve any private data sources -- it just analyzed public text on the web. (And yes, we do try to estimate reliability of the facts before incorporating them into KV.)
Also, KV is not a launched product, and is not replacing Knowledge Graph.

Unfortunately, I cannot do a more detailed Q&A here, but
if you want more details, please read the original paper here:
http://www.cs.cmu.edu/~nlao/publication/2014.kdd.pdf. (Note that an earlier version of the work was presented at a CIKM workshop in Oct 2013 (see http://www.akbc.ws/2013/ and http://cikm2013.org/industry.php#kevin). We have also published tons of great related research at http://research.google.com/pubs/papers.html

This guy is clueless. The whole point of bitcoin is that it appeals to people who want a decentralized medium of exchange. It's basically useless to large payment processors.
Yeah, it is depressing in the UK - the usage of antibiotics on colds (i.e. of no value to most people with colds) has increased 40% this century even with a campaign to limit usage.

I've personally spoken to a couple of GPs/Docs and they said after a few hours of people coming in and asking they get tired and give in.

Between that and farms using them like M&Ms (smarties ;-) ) on the cattle it seems like people are taking a precious resource and throwing it on the floor.

First you are mixing clientside and serverside development libs which are not the same thing. I believe there is little reason to use nodejs on the server. Yeah,it 'scales' , but so does the JVM or go. And frankly async programming the nodejs way sucks,even with promises or generators ,since there is no way to abstract asynchronicity 100%.

If you eleminate all the serverside tools, then you only need a framework (AngularJS for instance) and a testrunner ( like Jasmine,you can even run it on the browser directly). You might need a tool to minify code, but gzip compression,a cdn and caching are often enough to reduce the load.

At one point they had nearly 30 repositioning trucks in London (2-3 years ago).
At Waterloo Station they basically hand them off trucks directly to the arriving customers during rush hour.
Thanks for that. I've updated the title accordingly.
That one is called The Pirate Bay.
i think they are more than just being an online directory IMO. Having an online directory means you'll have to go to someone's profile to view their personal details but with news-feed and photo-tagging, You started getting updates on "our" news-feed about our friends' life and activities and about people they are hanging out with at parties/places. Online directory is more of asynchronous communication whereas now facebook is providing more of a synchronous communication.
SWIFT used to cover the world because it was 'neutral' to all countries. By banning Iran from using SWIFT several years back, SWIFT went from covering 'all' to only covering 'some' and thereby lost it's 'indispensable' reputation. Now it looks like another country will be banned from using it. That's called 'shooting yourself in the foot'.

The BRICs are now in the process of setting up their own SWIFT-like system, and as time goes on more people will use that system and SWIFT will become less and less relevant, instead of remaining the 'only game in town'.
DARPA is misinformed about a lot of things and has the money to afford being so especially if a few long shots work out.

Tobacco is not scaleable for rapid response because of the amount of time it takes to verify and grow a plant clone. The goal with pandemic flu is to get a rapid response vaccine kit for first responders, then to stage in higher-scaled vaccines. [1]

Ebola is similar. Unfortunately ZMAPP has this technical debt where their testing and validation is tied (understandable from a scientific and legalistic viewpoint but maybe not necessary the best outcome) to production in tobacco. There are better systems now, I'm thinking the new system called 'pichia glycoswitch'.

Gibson come in after the 'timed experiment', where he had a special fedex truck come in at 3am to pick up the package from his private residence; he joked that his neighbors must have thought he was dealing drugs. Although I generally dislike the scientific product coming out of the VI, this was one I had immense respect for.
I think you're focusing on the wrong part of the point being made by notastartup though. Given that people are going to try to make their selves look good regardless, it's wise to be selective in who you let into your newsfeed. Someone who connects with a lot of people they barely know will be worse off than someone who only accepts (and requests) connections to people with whom they have a close enough relationship that the happiness will always be mutual.

You mean that bonuses are the new raises for employees who work in a few narrow white collar fields? Sure. But really, the "new raise" for most of the proletariat is leaving your salaried job which won't give you a raise because "money is tight" (despite record profits) and finding a new job which will pay you %10 more. No loyalty from the employer begets no loyalty from the employee; this labor situation favors the employers, which is why it is so.

If we're talking realistically, there is no "new raise", and the majority of workers (especially hourly workers) don't get substantial bonuses whatsoever. There's yearly wages losing out to inflation and higher cost of living, and a stagnation in wage increases that has gone on for 30 years, on the broad view of things.

The article also mentions an "economic recovery" while failing to mention that labor engagement as a percentage of the population is at a 30 year low even when controlling for demographic factors. It's as though the author is living in a fantasy land where only positive information is taken into account when drafting an article.

Really nice editor.
That's not the true cost of accept VISA, since every time there's a chargeback, the merchant is also the one who pays the bill, not only with lost merchandising, time, etc but potentially fees (e.g. Stripe charges $15 per chargeback).
No, not even if you were willing to put up with arbitrary loss of some entries. For example, one of the required behaviors of a Python dictionary is that one can iterate through it, but this data structure can only be iterated if the size is small enough.

What Most Bitcoin Miners Don’t Understand
There's a significant difference between wanting to enjoy top-of-the-market luxury and wanting to avoid nasty financial shocks related to (probably) your largest economic expense. Landlords can buy eviction insurance for only around $10 per month but I don't see the market offering any equivalent for tenants.

And I'm pretty sure you don't want a rent a Honda Civic from a company that might decide to jack up the price half-way through your rental period, or lock you out of it regardless of where you happen to be at the time.
I have yet to meet someone who was left dumber by seeing Gravity.
First off, it's spelled "Bitcoin", not "BitCoin". Spelling it the latter way looks wrong in the same way that "FireFox" or "FaceBook" looks wrong.

Secondly, even if the author is correct about the $30/transaction figure - this is still competitive with bank wires, which currently charge $25 or more (often up to double that for international wire transfers).

Finally, there are many other benefits to bitcoin other than lower transaction fees. They're difficult to confiscate, immune to monetary inflation, and they don't require a trusted third-party.
While this is true for many, not necessarily for all, and I'd definitely call bullshit if you try to generalize it. It boils down to personal goals.

Let's assume I want to build a real-world helicopter. I don't work in that industry, nevertheless, I earn something reasonable, and I am happy with it. Money may not be a prime motivator for my everyday job, but any 'above-the-minimum-happiness' money contributes to my long-term plan of building a real-world helicopter. And having such a long-term goal, in addition with the money that helps me to achieve that will increase my happiness way more than I've had been just with the job and less money.

Having more money without a goal is not a motivator. Getting more money to achieve an already established goal is.
Maybe Wall Street is made up of "grunts" who understand the value of cash and properly discounts the promise of paper profits later!

My extensive experience of being a PayPal seller is quite the contrary. People request a charge back, PayPal "encourages" them to contact you, which essentially is just an extra step in the charge back process that they can skip, then nearly every time the money is returned with nothing the seller can do about it.
Yes, that is the primary use-case for a bloom filter, generally. I think parent is asking more about the added value of "invertible" bloom filters.
See the paper linked in the post below. It deals with exactly that 'economic approach' in addition to traditional repositioning with trucks. But with positive customer incentives instead of added costs.

There's a freely accessible preprint on arxiv under the same title if you cannot cross the paywall.

By the way, incentives do not need to be monetary. In Paris, they give people free minutes for driving bikes to stations that are uphill...
That sounds more like a fundamental concept than a basic one.
This paper is needlessly hard to read (4 pages in before there's even an explanation!) so first a refresher: A traditional bloom filter sets k bits to 1, using k hash functions to determine which bits. So for input 'i', we might get something like:

h1(i) = 0
h2(i) = 5
h3(i) = 7

and upon insertion, the bloom filter would resemble:

1 | 0 | 0 | 0 | 0 | 1 | 0 | 1

to check if an item is the bloom filter, you check the corresponding bits. After you add items to a bloom filter there's some probability that the corresponding bits for items that haven't been added are also set. So it can sometimes lie to you and say something is included, even when it's not.

IBLTs replace the bits with counts of items added, and a sum of the key and value. So where Cs is the count sum, Ks is the Key sum and Vs is the value sum, the filter might look like;

Cs=1 Ks=10 Vs=20 | Cs=0 Ks=0 Vs=0 | ...

the positions in the table are computed just as before; the count in the count increments for every item added, and the key and value "sums" are a union of the keys and values that have been added (this might be a simple rolling count of a small checksum, or an xor).

Items can be removed from the table individually, by subtracting them from the relevant counts (just like a counting bloom filter) and rolling sums. A "dump" of the table can be derived by iterating through all possible values (you need to know what they might be) and deleting them one by one, and it takes trickery to support duplicate entries.

This seems like a big downside; if the input set is constrained and there is so small a finite set of inputs that you can just iterate over them, then I think it is easier to use composite numbers as your invertible lookup table.

Here's how; for each potential input element, assign it a unique prime number, keep this assignment in a static lookup table. Start the table with the value "1". To store an element, multiply the current table value by the element's value. A composite number will be generated that is the product of all elements inserted into the table.

To check for element presence; just use mod. Duplicates work; if the value is still congruent, then the element is still there. To remove an element, just divide by its value. A surprisingly large number of elements can be represented this way in a 64k-sized composite number.

A good example of this this technique is to model Internet AS paths; give every AS number a unique prime number (there are only about 100k of them) and model AS path as the composite of its component ASes; using vectorized DIV/MOD instructions it is incredibly fast to large graph operations.

As I recall there have already been cases of cutting cables to move traffic to other cables which have better monitoring capability. But as for the lulz, I expect that even the most naive of folks who might do this understand that it would get them some serious prison time, and there would be a huge amount of effort put into catching them and making an example out of them. Not quite worth it I'd expect.

That said, we've had folks take sniper shots at power substations in California[1], which can cut power to big chunks of real estate.

how much does it really cost to clear a transaction?

One way to look at that is (25 BTC / block) / (# of transactions / block). About 60 mBTC/transaction given https://blockchain.info/charts/n-transactions-per-block

Fortunately the transaction itself does not have to pay for its own processing.

Humans are fit, to our current situation. That's the point. We are perhaps more flexible than many other species, but we are not infinitely flexible.

As the article, in one experiment, removing a top predator caused certain tree species to die off (the predator controlled the beasts that gobbled the trees). There are cascading downstream effects.

Removing half of all species might, just might, change the environment so much we no longer fit it, we can no longer adjust. Or perhaps some of us will survive.

Note that your last sentence betrays a common misunderstanding about evolution: some notion of superiority. Evolution isn't about superiority, it is about goodness of fit, how well various species fit their environment. This isn't fitness as in strength, it's fitness as in suitability. It's not optimization, it adequate-ization.
if walking dead and zombie movies taught us anything, it's that things can get a whole lot more sub-optimal.

Running my own large-ish Clojure service (CircleCI), I'm pretty convinced that futures are an anti-pattern in many situations. If your future is for side-effects, rather than for computation, the future call should probably be going on a durable queue being processed by a cluster of machines.
