Effectively, a lattice model is a decision tree about the different factors affecting an option's value, and thus the resulting value.

Exactly why I have never even visited Quora.

Facebook login required? Forgitaboutit. I've never had a facebook account and never will (sure, I know you maybe can use another service...but just it isn't worth my time).
I haven't read the book, but since the book is on inequality, it seems obvious to me that the problem is that the wealth growth is unevenly distributed, i.e. going mostly to the super-rich. So we have GINI-coefficients that grow rapidly around the world, especially in China and India, where globalization has also lifted tons of people out of poverty, and in the United States, which is still by a socialist government, if you listen to Republicans.
It seems like the usual solution to the marketplace problem would be essentially promising one side that the other exists. See a recent comment by Patrick (patio11) that explains this better that I can:

More specifically, you could look at doing manual work to make it seem like there is an existing market, similar to what the Reddit(?) founders did in the beginning where they create posts under different accounts. I can also think of services like TaskRabbit where you can supply or at least partially fill in for part of the market.
While we are at it, can we list some other addictions that we use to cope with life. Me personally, it's gambling, pornography, sulking alone, facebooking acquaintances to see how they're doing better than me or worse, checking sports score and living vicariously through the lives of professional athletes on and off the field, checking TechCrunch/Hack News and doing the same with tech billionaires, making up lists and goals alone or with other people that will never come to fruition due to excessive wishful thinking and ambition to overcompensate but fun to preoccupy my mind for the time being. Window-shopping online and offline for the perfect couch, jewelry, fragrance or other consumer goods that is marketed to me. Reading self-help books, attending wellness workshops, "social intelligence" workshops to help me with my awkwardness, tech-meetup's to mingle. Wasting money at pubs, lounges and clubs hanging out with friends by shallow association of work, school, social network where nothing of importance is said and egos are stroked and reciprocated.

Going home alone. Or accompanying a date back home but feeling alone. Or sleeping int the same bed, wondering how I got here and still feeling alone. But I'm just doing what I'm told to find someone, don't be picky, "you're not getting younger." Forging intimate moments like taking a trip to Montreal in July, go visit a botanical garden or go skydiving like what I'm told by Hallmark and merchants of the USA, I feel nothing but my CC swiped to the max. Keeping an overpriced apartment in downtown like a dumb bird nest-building for the sole purpose of mating and trying to fit in.

So I have to keep working and running round and round in the hamster-wheel to pay for my student loans, car loan, credit card debt, insurances, save up for a mortgage so I can take on even a bigger loan to convince someone that I may or may not like to start a family with me, so that we can both be indebted for the kids' college education loans.

But still everyday I wake up, and I keep braving it through. Because I'm hoping maybe just maybe, I can be like Mark Zuckerberg or Steve Jobs or Bill Gates. Hit it out of the ball park, that is the American Dream, work hard and if things don't work out, keep working even harder and harder, and one day freedom will come for me. I have to believe and try, after all this is the American way.
I will not be happy the day I go to the E.R. with some emergency and I have to talk to a machine...

I am amused to see this on the front page. I submitted it previously and it did not get a single upvote and I found myself wanting to post more and more quotes from it because I found the piece so fascinating. So I deleted it and did a blog write up about it (with all those quotes I had begun making notes of), and then submitted that, hoping it would have more appeal for the audience here. It also got no real attention.

So, apparently, luck and timing are huge factors in what does well here.
He did invent Tex (including a line-breaking algorithm many consider important), many credit him with the foundations of algorithmic analysis, and string searching (Knuth-Pratt-Morris) has many commercial implications.

I think he's done the requisite share of invention to have a perspective here.
Nice. I'm trading delta-neutral, volatility strategies on options using Interactive Brokers API. Right now trade entry is automated, but I do adjustments and closing trades manually. I spent a lot of time on tech, digging deep into C/messaging queues/distributed backtesting/event processing but I think best to use Excel instead of worrying about tech.

Well you have to take into account the amount of effort, time and manpower spend on different languages and (in-)directly on different paradigms.

FP hasn't been given as much attention as imperative programming languages, especially not when it comes to the important last step of language development, which turns ideas that are nice in theory into tools that are actually convenient to use.

Java is a good example for how much that matters. The language is inelegant and makes it impossible to express yourself concisely nevertheless the tooling is incredibly good, so good that it makes up for quite a few surprises.

A FP IDE that for example shows you inferred types and type errors while you are writing the code, would already help a lot as it could much better visualize the problem, than a compiler that has to describe an error purely with text.

FP languages are not perfect, no language is but they have the potential to be much more powerful in lot of ways than imperative languages. Lisp is a good example for this although it's also a good example that such power can corrupt people to use macros in awful ways.

In any case when it comes to the rhetoric especially from professors, you have to take into account that they have spent their entire life specializing on what they are doing. Of course they are excited by what they are doing and even if they aren't they have a good reason to lie to themselves consciously or not because the alternative is acknowledging they wasted their life on bullshit. They are biased and that's ok, you just have to be aware of it.
You don't have to do most of the things on your list. Own your decisions.
If person died from diabetes, but drank, this goes into
the "alcohol deaths" count, even if the person would have
suffered from it without the alcohol.

That would be a monumentally stupid way to conduct a research. Until you can show me evidence of this level of incompetence I'll assume you are mistaken.
Some Thoughts on Life and Technology
Pound for pound men metabolize most drugs (including alcohol) faster than women. A 150 pound man will be less drunk than a 150 pound woman who consumes the same amount of alcohol. On top of this the average man is heavier than the average woman.
But Knuth did an excellent job in writing down basic algorithms. And without those the other "inventions" would not been possible. I am also not sure, if Knuth himself invented some basic algorithms for which he does not get credit, because they are not patented.

Guess, what would have been happened, when he had patented Tex. I am not sure, if not some of our todays software would be infringing.

This is not a mindless down-vote, but I must shake my head, about your ignorance.

I couldn't parse that until I clicked the link.

So, it doesn't have a command line client, it's a website that offers a text based interface to SoundCloud.

I don't think this is what most people would associate with 'command line client' though, while the linked GH project actually allows access to SoundCloud data from the command line/shell.
Right. I think that there's a big difference (legally and morally) between the beams of light passing between my cell phone an the cell tower, versus something that's being broadcast specifically so that everyone with an antenna can hear it.
Would it be worthwhile to combine this with a service like tor2web, even if it means there won't be end-to-end encryption? I could think of quite a few situations where the anonymity of the downloader is not nearly as important as that of the uploader.

It took me a worryingly long time to work out that 1 cider per night over a week or 2 of summer was why I felt terrible the day after. I suspect this has more to do with the stupidly high sugar content.
Finishing up documentation and some cleanup before release on a Go logging library for LogEntries.
I believe the author meant that a bit more metaphorically than you are taking it. Scrubbed clean in the sense of removing the hard edges and character.. whitewashing so to speak. That said, the tech industry has definitely cleaned up areas of the city. Compare the area around the Twitter office today to how it was even a few years ago.

Also this comment is pretty harsh, and you clearly are not spending time in the right parts of San Francisco if you think its all littered with garbage and smells like piss. I will grant you that muni isnt great compared to cities 10x the size like New York or London.
FWIW I tried this service a few times over the course of a few months and could not get it to consistently work, and overall I wasn't impressed. I think a non-browser based one may feel snappier too, so I'm interested to see how this one works.

How to monetise the IoT through energy markets

Great idea. The main problem with TOR is the lack of nodes, so transferring any file will be very slow.
Seconding ZODB
Honest question: How much is too much?

I drink about 2-4 fairly strong beers a night (5-7% ABV), almost every night, and while I certainly feel it, I've only been "shitfaced" (or whatever you call "drinking to the point that you lose control") maybe half a dozen times in my life. The fact that I'm not doing the (apparently) normal thing for young folk and getting trashed every Friday night (or ever, really) gives me some relief, but I often worry about how much damage I'm doing with my less intense but sustained drinking habit.
Any time you need to do multiple things at once, erlang (or elixir) is often the best choice.

EG: If you have a website and want to serve more than one request at at time. If you have multiple people chatting or sending mail, or instant messaging, or voice communicating, erlang is a good choice.

If you have a search engine with many people searching, while spiders crawl the web, erlang is a good choice.

The only "downside" to erlang is new syntax and that its "slower" on a given node. But this last one isn't really a downside-- you can scale a process to 20 nodes with erlang a whole lot better than, say, node.js or java or go. None of those really support concurrency properly (of the ones who even try.)

This makes erlang unique.

I think many engineers try to tell themselves that the JVM or node.js or Go can be concurrent, but they are really just making excuses for the fact that the erlang syntax is a bit of a hurdle for getting started.

I'm fine with that- it makes a great hiring filter!

If someones learned erlang, you know something that makes them better than most of the rest of the programmers out there who are happy to believe rationalizations that let them get away with not learning erlang. (And if you're not thinking about concurrency you're even further behind.)
I'm sorry, but I don't see any much use in this visualization. It's pretty, but gives almost no information at the global level, for two reasons:

1) It's not adjusted for population ( http://xkcd.com/1138/ ). They can normalize the data to fix this.

2) The map is ludicrously distorted because of the Mercator projection. Greenland looks bigger than the entire South America, when it should be an eighth of the size. This directly affects the perceived density in each area. Suggestion: if you are using an interactive geographical visualization, why not display a globe?

However, it does look stunning.
It is surprising how few of the projects have actually monetisable products not aimed at the developer niche.
This is one of the projects I most admire in the space. It's the ideal I set my programming learning around when I started teaching myself this stuff. Upvoted

Someone will have to parse the study to find out what's really happening. My guess is that most of the deaths that are being called alcohol-related are not chronic alcoholics; most are probably accidents and violence in which alcohol had been consumed at some point. So, I would be cautious about reading causation into those statistics.
I would have thought that 30 seconds thought would give a few of the answers. Basic anatomical differences like a uterus and breasts are part of the equation.

"Heroku sends them as a normal course of operations."
Wow, I didn't actually know that. Makes me glad I didn't pick Heroku recently for one of my mini-projects. It requires long-running processes.

I guess Heroku "dynos" are more suited for "worker" type jobs, then. In which case, sending the TERM signal to all processes isn't necessarily a really bad way of notifying the worker to shut down. Although, we are in 2014, and I don't see why they can't easily come up with a more robust solution. Even if it's in the form of a "shut-down" process, or giving the worker more than 10s to shutdown.
Habit forming and toxic, so no. But yes, they were banned.
> If software patents had been commonplace in 1980, I would not have been able to create such a system, nor would I probably have ever thought of doing it, nor can I imagine anyone else doing so.

I don't understand this. How would patents have prevented him thinking about it ? I don't understand this logic.

I totally agree that software patents are abusive and most of the time not useful to society, but why say it would prevent people from inventing stuff ?

Even if someone steals your invention, if it's a real breakthrough it will be used, don't you think ?
I think San Francisco's tolerance of diversity and oddity correlates to a greater tolerance of civic disorder than you see in other places. That said, it's often a much different city at the top of the hill than at the bottom.
That kind of nitpicky detail won't matter to the entertainment lobbies that effectively own a huge chunk of our government. Aereo was already built on a bunch of clever, detail-focused legal loopholes and caveats that should have protected them, but the case got reversed at the supreme court after they won.
Show HN: Interactive Fiction game management for Parchment
We might consider what we mean by wealth and concentration. If we mean money, perhaps. If we mean economic benefit, perhaps not.

In a previous HN thread, we considered the possibility of medicine becoming automated, imagining that (say) 80% of doctors’ labor is replaced by machines.

In this case, the monetary earnings of many doctors will go away, and those earnings will instead go to a small number of technology companies who make the products that obviated them. That feels like concentration.

If this happens, it also happens that medicine will have become dramatically cheaper, and therefore more available to a greater number of people. Thousands of doctors lose while millions of humans win. This feels like egalitarian distribution.

So perhaps we’d call these technology companies ‘oligarchs’, yet economic (not monetary) gains have gone to a much broader set of people than before – anyone who consumes medical service.

If there are several such technology companies, they will compete, reduce prices and increase the widely-distributed consumer surplus. This can happen simultaneously with their CEOs (oligarchs) getting inordinately wealthy.
That's a silly thing to say, really.

I will elaborate on my point in case you missed it, form should follow function, this principle applies to architecture just as much as a website.

The case with the current trend of animating everything into place reminds me of "Ornament and Crime" which is another architectural idea that can be equally applied to a website.

To be blunt, it simply means stop animating/decorating shit into place for effect, it is meaningless and a disservice to real design.

> there is a great deal of room below 100%, that would both allow for redistribution of wealth and for plentiful motivation for the overachievers

Indeed. The lowest top marginal tax rate in the U.S. between 1940 and 1980 was 70%, and it went as high as 90%. That didn't exactly kill innovation or growth.
Free and low cost ways to grow an amazing blog
Depends on the implementation. GnuPG picks the most recently created encryption subkey and uses that one. It doesn't use both. Not by default anyway.
Without HTTP, it'll be a little clumsy. The downloader won't be able to pause and resume the download, and won't know what is the progress of the download (unless you tell her the exact file size beforehand, which might be tricky sometimes, especially in automated circumstances). You will also need to resort to this for sharing the metadata such as the MIME type of the file.

I think using HTTP for this is more robust, even if it requires you to download and spin up OnionShare.

Btw, the fascist firewall evasion is great. In my dorm, the only allowed ports were 80 and 443, and I was able to connect to Tor effortlessly.

There is no claim that the density means anything, so there isn't any need to adjust it for population. I imagine the title "OpenStreetMap node density map 2014" was somewhat carefully chosen, and it manages to say what is shown.

Help me understand this ECB attack
It's pretty old i guess now (2012) but i'd still like to able to understand the adaptive chosen plaintext attack on AES-ECB. Specifically, how it's explained in this video from Thomas Ptacek's talk on crypto: https://vimeo.com/41116595

I can understand how we identify where our block boundaries are, but repeatedly injecting known plaintext (32 or 64 A's for example) and then appending another known string, but this time with a different value (another letter in the alphabet). From this, build up a dictionary of ciphertext that we know the plaintext for.

My problem is i cant understand how the attack gets implemented practically, for example in the video it's suggested to include a pipe character | (thats @ 45 minutes in or so) but i cant see how this would lead to a decryption?

"If you sell network equipment, the basic concept of comparative advantage almost guarantees that Cisco can do a better job extracting value from it than you can."

Doesn't take into account branding, sales, and marketing of a new organization which are always able to drive business purchases. Even in face of a formidable competitor.

Of course if you want to look at things at a point in time you could also be correct. But roll back to when Cisco started and see if there were companies that also had "one of the world's most powerful enterprise sales operations" that lost out to someone else. Like Cisco.

So while you could be correct it's also possible that "many networking companies sell to Cisco," because it's a "pay window".

After all wouldn't that be one of the reasons that you sold your company?
There is a good LSE podcast of a Pikkety lecture - hard to follow in his accent but interesting. Anyway, he mentions Europe has the greatest accumulation of wealth yet, but does not mention the massive tax windfall that will be inheritance tax after the baby boomer generation pass on - it may be that instead of using income tax to adjust inequality we simply uE inheritance tax to redistribute the wealth

"each generation should earn their own way" could be Pikkety new and less attractive call to arms
I am making a "paddle game synthesizer." It is a Pong-style game engine that is designed to have all game parameters be easy/fun to tune, from the game's physics and logic upwards to the audiovisuals. It also includes connectivity options so that MIDI devices can be used to control parameters.

In parallel with this project I am also working on a longer-term software sound synthesis project - a framework containing synthesizers, effects, and sequencers.
