> So, i see there will be a lot of virtual currency flying around, all of it as qualified as bitcoin (sharing similar source code) and the idea that it will all be worth 1,000 a unit (or more) forever just doesn't make sense.

Do you remember the time when twitter was the new hotness? And like everybody and his aunt where building a twitter clone. I mean, it's so simple, just a list of teensy messages, how hard can it be. And we joked how the operators of twitter had like a couple servers and some louse PHP scripts to glue it all together, it was just so laughable from the outset. And most laughable of all, people where flocking to it like mad.

Twitter is the remaining "twitter like" website, all the clones quietly shut their doors again and twitter went public with market cap valuation of $22 billion...

I could now ask: Are you kidding me? A website where people can post 140 character messages is now worth $22 billion.

Ah but the wonders of the network effect. You see the value isn't in twitter. The value is in who uses twitter. Because everybody uses it, it's valuable, and because nobody used the clones, they're not valuable.
He's right, sort of, about some things. Bitcoin is absolutely in a speculative bubble right now. People are buying it not to use as currency but to sit on it and watch its value appreciate. That's not good. Lots of people will be hurt when the inevitable crash occurs.

The bigger problem is that Bitcoin has intrinsically a deflationary nature. That's not a great property for a currency to have. Currency is meant to be spent. It's not meant to be buried in a backyard so that you can watch its value grow.

His points around the development of currencies are bunk. The fact that in the old days it took any currency decades or centuries to take a hold, is purely a function of that time. Bitcoin also does solve some big problems with the current financial system. Specifically today it's pretty friggen hard to move money around because of the insanely strict regulations around transfers. In an era of the internet and all that it enables, there is a huge pent-up demand for something compatible with "the internet way of thinking".
I'm aware of the definition of the term and its origins.

Data Scientists and Data Engineers like Python and Scala
Because you'll be an "early adopter" and there may be a good chance they'll go from $3 to $1000 eventually just like bitcoin, if they are subject to the same network effect as bitcoin -- namely that the more merchants accept them, the more valuable they become. It may take longer but you'll make more $, etc.

So you'll buy them because of speculation. Hence the proliferation of these various currencies, the latest of which -- QuarkCoin -- is probably going to surge tomorrow on Bter.com and other exchanges :-P

> Someone with your background should be a top pick
at any quant desk, among other places.

There is a book, now old, E. O. Thorpe, "Beat the
Market" where at the end he said that an argument
was from measure theory. So, in graduate school,
I made sure to get a good background in probability
and stochastic processes based on measure theory,
from a star student of E. Cinlar, long the main guy
in financial math at Princeton. Yup, I was the only
guy in the class who was able to show that there are
no countably infinite sigma algebras!

No help.

Once I wrote a letter to Fisher Black (of
Black-Scholes) at Goldman Sachs and got back a nice
answer saying that he saw no opportunities for
applied math on Wall Street.

I live 70 miles north of Wall Street and did
interview at Morgan Stanley. Mostly they wanted me
just for software, but I tried to indicate an
interest in mathematically driven automated trading,
but they had no such interests.

Once a guy who recruited for Goldman Sachs took me
to lunch, but there was no interest.

I learned about James Simons only much later.

Heck, my Ph.D. dissertation was in stochastic
optimal control -- still no interest.
Real business thinking. You can't make a product yourself, you inexplicably need a bunch of other people around doing stuff for it to work.

> I know it’s romantic to think that one person can create an incredible product in isolation. If that’s what you believe, stick to reading romance novels, and stay the heck out of software development.

This is the only fallacy I could find mentioned in the article.
Probably not true.

You may also get to do a bit of robotics as some of our software controls needles and dials too.
Sure, but your hilarity may be coming from someone else's tragedy (or certainly something they probably don't consider funny), and maybe you're not being loud you're just sat somewhere you can be overheard?

That said, horses for courses - we can agree to disagree :-)

MarkLogic is an XML document store, with the usual shift in access patterns which that entails. I could easily see much of the problem simply being an impedance mismatch with devs & other systems expecting SQL-like behavior.

I haven't worked with it directly but at several places it has a reputation for high memory requirements and requiring you to scale by getting single massive servers rather than clustering – I'm not sure if that's still true or if it's an issue for healthcare.gov but it could definitely make it harder to scale in a hurry.
By your definition, every government that has ever existed is socialist. Consequently I doubt the utility of your definition.

You bet! I guess it will be on from those blogs who would have just got listed on Google News or something.

Well my observation is that programming puzzles that are top in the difficulty tree often typically involve trees, graphs, queues, or bit manipulation and in my experience, they aren't usually encountered in programmer's average life. As it is not easy to get them right the first time for an intense visualization exercise they involve, preople often find them lost and give up their hands.
Spantree - http://www.spantree.net/jobs - Chicago, IL

We're Spantree, a small, nimble boutique consultancy based mostly in Chicago. We're looking for another smart person to join our team in the West Loop of Chicago. This candidate should enjoy learning new things and solving hard problems.

We work almost exclusively with open source software and we're not shy about jumping into third-party code to figure things out. You should be motivated to submit pull requests and hunt down project committers on Twitter and IRC when you're stuck.

Some of our favorite day-to-day technologies include Groovy, Grails, Elasticsearch, Drools, MongoDB, Backbone.js/Marionette, CoffeeScript and Puppet.

Our clients range from small and scrappy startups to large hospital networks and software as a service providers. Historically, most of the stuff we've worked on has not been public-facing: it's either guarded behind the client's firewall, neatly tucked away as a library or jammed into the minds of the developers we've mentored. But we're starting to diversify from "behind-the-scenes" work to more early-stage product development.

Fundamentally, we like to work on tools that helping people make better decisions. This can take the form of a search engine to help people find interesting stuff to do on a Saturday night, a complex workflow management system for evaluating health insurance claims or a matchmaking and scheduling system to help people book face-to-face meetings at conferences.

We're looking for generalists who can quickly go from problem to working solution and communicate effectively with our peers and clients along the way. While we have a very strong technical stack already, you don't expect new hires to be an expert in everything right away. In general, though, we're looking for people with the following qualifications:

* One or more fun languages: Ruby, Python, Groovy, Clojure, PHP, CoffeeScript, etc.

* One or more boring languages: Java, C++, C#, etc.

* One or more web frameworks: Grails, Rails, Django, SpringMVC, Play, CakePHP, etc.

* One or more databases: SQL, NoSQL, NewSQL, we like it all.

* HTML, CSS, JavaScript and at least one framework

* Git, or a colorful excuse for not knowing it.

* The typical software development toolchain: text editors, IDEs, step debuggers, issue trackers, etc.

Where Factory Apprenticeship Is Latest Model From Germany

It's like a "list of all North American phone numbers" that goes:

000-000-0003
...
Yes, indeed. It is very effective and this is why it is so dangerous. Mind police stuff occurred the last century in Germany two times in a row with devastating results.
And there I was, thinking I had an original thought.

Then again, this just moves it from clever joke to irony. I'll take it.
Strong parallels here to the case of equity in a new business. It wasn't worth $1B when they did the work, and the likelihood that it would ever be worth a significant amount was low enough that the reward would have to be high to be a useful incentive.

In addition, everyone who bought in over the years implicitly accepted this deal. I'm sure if the inventor had claimed 50% of the total currency pool, there would have been less interest.
Reminds me of the classic "all the ipv4 address in the world - tools for hackers!.rar" joke.

Good job :)
Why? The purpose of embarrassment, as I understand it, is to create emotional significance for something that negatively affects others. So unless you are talking about something vulgar or being offensive you haven’t done anything socially remiss.

This isn’t to say I condone live tweeting of behavior that is socially remiss. In those instances one should think carefully about how to influence that person to do better. Humiliating them on social network is not it. You lose any moral high ground the second you do that. Personally speaking I also think very carefully about whether it is worth my time.
SEEKING WORK- Remote or Bay Area

Every website and marketing push involves content. But is your content effectively supporting your business goals? Is it performing as well as you want it to?

Chances are, if you hired a writer, or if you did it yourself, your content could do more to achieve your business goals. The missing ingredient is usually a careful combination of information/UX design, content, and ongoing testing.

I CAN HELP
If your content is not performing as well as you'd like, or you need new content for your marketing efforts, let me know and I'll gladly take some time to chat with you about potential solutions. If I'm the right fit for your needs, I'll share work samples and work up a proposal.

Clever.

I bet the creator hopes that panic will ensue, and that he/she can buy some extra bitcoins at a lower price. I might buy a few now, shouldn't be a bad idea. :)

Are you calling the woman abusing a flight attendant and the couple loudly breaking up on a rooftop "victims", or are you just referring to the more mundane events?
To be fair to the original article, the author does point out isolation is helpful 'when you are focused on a task':

"As for flow, it works best when there is a specific, narrowly scoped piece of code that must be written. For that work, being in a quiet place free from distraction is ideal. Just don’t stay isolated too long"

I don't see much to disagree with there. I think the point of contention is on what should be the default work environment: an open plan office with "concentration rooms" here and there or individual offices and occasional meetings. I don't believe there will be a definitive answer, it depends on team dynamics and company culture.
1) Nope. This initiates the transfer - but (at least here in Europe) it will take at least one bank day if you're sending money across different bank chains. So, bitcoin is faster in the full cycle.

2) There are reasons you do not want the state knowing what you do. The less the state knows, the better.
Hyperbole. Notice how lackluster their "targeting" of the Guardian has been:

The editor has been asked to appear before parliament. He'll be asked some questions. Which may also give him another opportunity complain about the harddrive destruction incident. Parliament regularly summons people, but the worst they will do to these people is ask them awkward questions and make stupid statements.

The destruction of harddrives was downright farcical and distasteful, but of relatively low importance: The Guardian were not forced to.

They were given hints that it might be bad not to destroy the drives. Even after pointing out that of course they had copies, and being given plenty of time to make further copies should they need to. So they decided to go along with it.

There were no thugs forcing their ways into their offices, nor any court orders forcing them to comply. They let some humourless GCHQ people into their offices voluntarily, and destroyed some harddrives everyone involved knew had been copied, and so everyone involved knew they were going through motions because the government officials had no powers to do more, but presumably had orders.

Cameron and ministers have complained loudly, but despite that they've so been totally impotent when it comes to actually do anoything more than inconveniencing Miranda at Heathrow for a few hours and arranging a voluntary ceremonial harddrive destruction that just made them look stupid.

I'm not saying it's not bad. I find it shocking and disgusting to see how politicians have responded to this. Cameron time and time again makes it clear that he has no respect for the public.

But if anything, it has also demonstrated that the UK government appears to only be able to respond to the publication of classified material in a way that is more perplexing and comical, in a way worthy of a Monthy Python sketch, than scary and intimidating.

I almost wish I had secret documents I could publish, so I too could get to experience first hand having GCHQ come to watch me pointlessly smash a harddrive (smashing a harddrive properly without powertools is hard work - I recently had to dispose of a bunch of drives at work...)
I love how whenever a new technology comes out the amount of applications are never fully apparent.

When I first heard of bitcoin back in 2010 I thought it was a cool concept, but sending money to unknown people across the world? That never crossed my mind.

Now that I think about it, we do it all the time in the forms of charities. Tsunami victims on the other side of the world, a fund is set up to help them out, and most people might say, I'll chip in a dollar, but I can't be fucked to find out how, and sending a dollar is hard anyway. Then mobile phone operators started offering SMS payments, and people had a simple solution.

With cryptocurrency this solution is even easier. It wasn't until it actually happened that this clicked for me.

Consider telephone for example, initially it was used to talk to other people over a long distance, but it was thanks to that concept of sending information down a wire that made it possible today to eg. look at a live webcam on the other side of the world right now.

Imagine telling someone 200 years ago that you could talk/see a person on the other side of the world in real time. Remember, phones didn't exist, motion picture was unheard of etc.

They would think you are mad.

It would be as unbelievable as saying today you can use buy a Rolex watch made in Europe online and it would be teleported to your desk.

But who knows, maybe this will be possible in the future.

And maybe in retrospect it would have been obvious.

In majority of cases yes, but there were also several instances of basic social engineering to obtain pin resets. That was about the only thing remotely approaching 'a hack'.

Mulcaire was no Mitnick, that's for sure.
That sounds like a great combination. I've found that volunteering and traveling are wonderful in themselves, but also 'unlock' the ability to write and produce things I want to produce, rather than sit around and do nothing (and eventually feel bad about it).

I'll be embarking for something similar, but for about a year.

I wish you all the best, and would love to hear what you have to say about humanity.
I think the point is that people aren't buying bitcoins like I might exchange my money for South African Rand.

When I exchange Dollars for Rand, I can more easily use the Rand to purchase goods and services in South Africa. I'm not speculating the Rand will be worth more in 2 weeks time. I just want something more fungible.

It seems people who are buying bitcoins now aren't doing so to purchase goods/services. They are buying and hoping the price goes up.

I'm just guessing but I'd bet most of the transactions happening now are for speculative purposes and not for increased fungibility which I believe to have been the point.

If people keep buying as an investment, they'll eventually start cashing out and the herd will follow to avoid losses.

Bitcoin may recover after a future crash but because nothing is really backing it, it's likely it'll fade into history.
This is like in an interview context. The basic point to the question is at the highest level--how would you write such a parser, what might be some of the steps, what exactly is an entity.

It seems like you are addressing a question of total implementation. But in an interview, I would expect a candidate to be able to answer--not fully implement--what some of the basic steps are. As opposed "use a library".
Well, but the problem is: when is the money actually on your bank account? With BTC, as soon as the network mines a block with your transaction. With anything involving multiple banks or even cross-continent transfers, the delay will be >1 day minimum.

If you could compute at infinite speed and merely needed to store all the possible key pairs in secp256k1, you'd need about 10^59 exabytes of storage.
But do you think the intersection of Bitcoin investors who actually know what a private key is and people who don't get the joke is big enough for that?
Agreed, but the affair is called that in the media.
Inevitably you have to trust some expert opinion because there isn't enough hours in a day to research everything yourself. I don't know about you, but someone who holds the insane views that this nutbar does, would certainly make me question his competency to give sound economic advice.
