Hey there, Nick from Websolr here.

Of course I'm a bit biased here, but where search is concerned, Solr is a really great option for you. Certainly I don't need to rehash all its features and benefits here, when you could just as easily figure that out with a bit of light research :)

It's a very fair point that getting started with Solr has a bit of a learning curve to it. With Websolr we (fizx and I) think we at least have taken the hosting and configuration side of that off the table. But there are still client libraries to learn, and schemas to configure. I think learning some of those basics is a great investment that will pay off, but the up front cost is certainly there.

A word about crawling: it's definitely doable with Solr. The advanced approach is to use Nutch[1] to fetch and feed content to Solr. The simpler way is to use wget. In fact, I've got a basic shell script[2] to show off the latter :)

I'm always game to talk about how Solr can see more general usage, particularly when it comes to lowering the cost of getting started. So feel free to keep the questions/feedback/brainstorming coming.

I was under the impression they were using the brand in an attempt to get the people to do what they wanted (use their crappy open source infrastructure).
I sure have, look at my other comments in the thread.

And I agree, it's hard, and not everyone can do it.
Doubt on Anti-Aging Molecule as Drug Trial Stops
There are a few nice places around Chicago. Have you been to Ten Ren?

Edit: Most of the places in the child comments are great too. I'd personally try to avoid Teavana, though. From my experience, they take low grade teas and sell them for a much higher price for the masses. I've also seen paint come off of some teaware there with little effort.

Isn't it one storage space per vnode? If you have 256 vnodes in your cluster and each vnode is at double digit gigabytes, you end up with between two and 25 terabytes available in the cluster.
> I can imagine that only someone who has never been through years of systematic abuse / bullying would lay the blame on the victim.

I'm Chinese and I know plenty of folks who went through this abuse. I know many kids who did stand up to the abuse - and as a kid who stood up to my parents (and whose parents changed because of it), I despise this horrible stereotype and wish more kids would muster the constitution to fight it.

You can only imagine nothing. If you weren't brought up in or witness to this kind of environment I don't even really know how you can make conclusions in your imagination about me.
Unbounce is another reasonable alternative. It is not specifically made for A/B testing but it has great functionality for doing so.

There have been websites that have done this for years. They are called on-line arcades and people go there to play games. You can even sell advertising on the site to make money. Go figure.

But gamifying something that is not a game, well, that must be different, right? Somehow...? I'll use the word "engagement," there we go.
That is a totally different discussion. The title of this article is misleading since the exchange that they are creating for supposedly, value investing, doesn't really allows any value investor now, does it? Other than of course institutions.
I have this thing about learning stuff. If I find something hard to understand, it is normally not me it is my source. I have years of proving I could understand stuff, but these authors generally don't have that level of experience in teaching stuff.

I remember in my A-level Computer Science class when we had to explain stuff, the lecturer would give an automatic zero if it didn't come with an example. I carry this practice with me now of giving examples when I'm trying to explaining stuff and non-technical people have commented they understand the concepts behind some of the technical things I write for them. I find that a lot textbooks fail to provide enough examples and analogies; they present just equation and abstract concepts. It amazes me how people find OOP hard to learn. Then I realize that my lecturer was off the chart in explain stuff. Tons of analogy and the like.

So, yea that is how I judge technical books, how many examples and analogies they provide.

I don't understand that last sentence at all.

HFTs demonstrably are liquidity providers. That's a technical term with a real meaning: liquidity is the ability to trade when you want to trade in the quantity you want to trade it, and it most certainly is not a natural property of the market; in order to buy an instrument, someone has to be willing to sell it.

Meanwhile, what is a "giant money sink", and how is that what HFTs are? I see how HFTs cut out the middlemen who used to profit from volatility, but the low-tech traders they replaced were not themselves value investors.
> not having it obviously isn't too much of a problem because so few systems currently have it

You can't really draw that conclusion. Other systems do not have it because it is not an easily solved problem, not because they do not think they need it.

Also, needing and benefiting from something are two entirely different things. Yes, no language actually NEEDS this kind of thing. But a language that has it is literally self-healing, since any kind of problem, be it breakages from dependencies, cross-platform issues or core language changes are communicated very rapidly to the developers without them even needing to make an effort.

A thousand times this. Not only do abused people not know any better, they're actively prevented from knowing any better. It's how abuse works.

It's especially terrible when parents do it, because children are naturally, genetically predisposed to try to seek approval from their parents. If they can't get it, or if it's contingent on something as arbitrary and pointless as playing a piano, it will destroy them for life.

I'm not a parent, and after my childhood I didn't think I'd ever want to be, but reading that article gave me new hope for myself: if anyone tried to do to my hypothetical children what the author is doing to hers, I would kill them. Instantly and brutally. That's got to be some kind of a qualification.

No, but not because of formatting, etc. Right now, you need to figure out how your resume is going to not just be screened out. The best way to do that is to customize it for each job you apply to. Make it so it's obvious that you are qualified for the job to someone who might be giving it a 5 second cursory glance (because they are looking at 100 resumes). That means using the keywords from the ad, customizing a letter highlighting how you match the requirements of the ad, and formatting it to stress the specific experience that is the most relevant.

The Linked-in version (or anything it generates) can't do this effectively.

Some books are bad. However, some of the best books shouldn't be easy to read. I think there is a lot of value in struggling through hard books. At times I think the internet has made things too easy.

Look at any great math book. Large leaps of logic are declared 'obvious', and left as exercises for the reader. While such exercises often aren't easy, struggling with such exercises helps you learn. Before the internet provided tutorials for everything, you had to really struggle when you couldn't figure something out. Yet, I think I really learned to program from that struggle.

You learn to find information that isn't spoonfed to you. When you do, you will better be able to dig beneath hype and propoganda, and make up your own mind. Look for clues, and try thinking for yourself instead of getting all the answers from someone else.
The Fermi Gamma-ray Space telescope orbits at 550 km - I'm not sure how large its Gamma-ray Burst Monitor is, but, it's probably on the order of magnitude of a square meter.

From the graph, a TGF creates an additional 80 impacts per microsecond. Under the (admittedly incorrect) presumption that a TGF is omnidirectional, that would suggest a TGF is emitting enough positrons to cause in 10^-6 seconds an increase of 80 impacts on the 1 meter section of the surface of a sphere with a 550 * 10^3 meter radius.

If I don't munge the math, that would suggest each of these TGF is emitting approximately:

4*Pi*(550*10^3 )^2*80 /(1*10^-6 )
3*10^20 positron emissions per TGF that make it to the LEO of the satellite.

Divide as appropriate to account for the likely (per the article) non-omnidirectional nature of the burst (they tend upwards)

Not sure how many are normally absorbed in the atmosphere, or, in fact, if 10^20 is a significant number of positrons - but I'm thinking it would be interesting to mount a TGF detector near, or above, a frequently hit lighting target (Empire State Building gets around 100 Hits per year)

Checking Wikipedia - it turns out that lightning has been a well known source of Gamma Rays for at least 15 years - I read about the observations of the Compton Gamma Ray Observatory in 1994 - and compared it to the more recent discovery by the Fermi Gamma Ray Space telescope. It's hard to see what they discovered that was different this time around.
You: "They are trying to get incentives right, rather than outright banning HFTs."

Article: "Firms that fail to meet standards aimed at protecting long- term investors won’t be allowed directly on the Credit Suisse venue"

So it's both: They are outright banning AND adjusting incentives.
Authors of books on niche topics prefer to sell paperbacks just so that they can reduce piracy. E-books are often easier to pirate, and niche-topic authors don't fancy losing huge chunks of their sales to pirates.
My take on the money sink comment:

If there are n people in the market moving money around in a closed system then the combined wealth of those n people is constant.

If another person joins in and is making a net profit then it must be the case that the combined wealth of the original n is decreasing.

Admittedly this relies on money not being created or destroyed, which may cause the model to be a poor approximation of reality.

I'm not sure if I'm following your point. Are you suggesting that anonymous inner classes aren't useful in a well-designed Java program? If so, I'd have to disagree.

As an example, the Java Collections API (one of the most well-designed Java APIs, imho) uses Comparators extensively. It's pretty common to define the Comparator as an anonymous inner class when you need to do a one-off sort() or max() call.

Scala just makes it easier to use this pattern. There's no need to go through the effort of wrapping the function in class if you're only going to use it once.
That's a good point, that people may be bound by contracts already, yet looking to buy a new phone. I'm sure I'll buy a new phone or two by the time my two year contract is up with Verizon in 2012. As a mobile developer, though, I was already going to buy an iPhone 5 and a Nexus.
yes, afaik, that is correct. atm, there is one bitcask "cask" that is opened for each vnode. the number of vnodes (virtual nodes) each physical machine is responsible for is a function of the ring size, aka total number of vnodes in a cluster, and the number of physical machines in the cluster.

This has to be an age thing. When I was 10 I shitted (shat?) all over people's work. Now that I'm 25 I have nothing but respect for people who produce.
I dunno, I worked with one designer who firmly believed that "users like a challenge". He loved little tricks like "hiding" clickable things by making them blend in with decorative elements, he liked unusual fonts, he liked layouts that forced the users to hunt all over the screen for the next thing they wanted.

But we weren't making games, we were making corporate Intranets. So my advice is, ignore your designer and try using something he's designed. If it's easy and intuitive, he's a good designer. If it's not, put him on the silly little scooter he'll invariably have and push him gently out of the door... Especially if he tries to tell you "you don't understand design, maaan"!
the window merge is a new thing in riak 0.14, i believe. and you are correct the merge is only a consideration based on your use case. if you are using riak as a pure dump of immutable data you will not need to merge. if, however, your use case consists of a number of edits you should consider a more aggressive merge strategy. As all updates/deletes are appended to bitcask and are actually writes, your dead bytes will start growing rapidly.
It's easier to critique than to create. For what it's worth, there are many more critics online, which ultimately intensifies the problem.
Exactly. Same case up in North Dakota. AT&T now owns Altel and has finally rebranded it, making it the second biggest carrier here behind Verizon. But, as far as I know, they're still running Altel's CDMA network. Not sure if they're ever planning on building out a GSM network.
GIMP has no support for the Pantone color system either. Another reason professionals tend to avoid it. Not the GIMP's fault, as Pantone is proprietary. But regardless, it's used heavily in the design industry.
Little Rock?
There's a middle ground though. You can be very critical and tough and still provide feedback that helps point out weak spots and suggests ways to improve things.

Problem is that it's easy to complain, but hard to provide constructive criticism that helps push things forward. So the "shitters" resort to complaining.
I think banning is a little strong, article:

Opportunistic firms, which Galinov says include some high- frequency trading companies, will be kicked off the platform and prevented from providing orders or executing against bids and offers directly through Light Pool. They’ll instead have to go through the Jersey City, New Jersey-based National Stock Exchange, where Light Pool will also publish its quotes.

so they can participate, but they get penalized.
Criticism is good for a creator. If you can't turn criticism into a force to improve your product, you're doing it wrong. (Granted, baseless criticism doesn't count.)

And if they're violating Apple's HIG... Seriously, why? That should be the easiest thing to get right. They've outlined it for you.
I'm not familiar with Scala but I don't understand how it could eliminate the need for Item 14: Use public accessors methods rather than public fields. The point of using accessor methods is so that you can change the underlying implementation if necessary. If the getters and setters are compiled automatically for you it doesn't seem like you'll be able to change the underlying implementation without also changing the types of the methods.
The stock market is not a closed system. The total value contained in the markets rises over time.

What investment markets provide is a way for firms to increase their productivity. Think of the farmer who has a bucket, a stream, and an acre of land. The economic pie gets a lot bigger if the farmer can secure an irrigation system.

The farmer can solicit the banker in town for a loan, or he can enter a debt offering into large market or exchange. Investors are more likely to invest if they know that they can exit their investment freely. i.e. there is liquidity, so they can sell their investment as their own needs dictate.
"When I was a boy of fourteen, my father was so ignorant I could hardly stand to have the old man around. But when I got to be twenty-one, I was astonished at how much he had learned in seven years."

Apple's HIG isn't the end of UI design though. Even Apple refuses to blindly follow it.

It's a guideline. Not hard and fast rules that must be followed in all cases.
I agree that just shitting all over people's work is, well, shitty. But I disagree entirely that the anonymous critic behind Read the Fucking HIG (http://readthefuckinghig.tumblr.com/) is out of line or that this kind of criticism is lacking in merit.

Firstly, it's clearly a bit tongue in cheek: "The evil doctor cackled as the thunder struck his lightning rod, giving life and sentience to his unholy creation, spliced together from iphone, ipad and mac ui." And the vulgarity is right in line with other satirical, single purpose sites like http://www.whatthefuckshouldimakefordinner.com/ and others I can't think of right now.

Secondly, he's got a "legitimate" complaint. You don't have to agree with his point, but I think a lot of people who are passionate about design (and about design in the context of their Mac) really, really do experience visceral rage at the way Apple flouts the HIG. A site like this is really just capturing that zeitgeist and reflecting how heated people actually feel about the topic.

Anyhow, I really am a big proponent for civility in discourse (that's why I'm always reading HN), but everything has its place.
Definitely a crazy story and will likely remain one of the most perplexing "unsolved crimes" of our time.

On a related note, though, it seems Hollywood is making a comedy based on this. Yes, you read that right, a COMEDY. I'm not usually offended by things, but I think that's kind of sick. The movie is called 30 Minutes or Less and stars Danny McBride and Jesse Eisenberg.
I agree, and will also point out that the referenced site (http://readthefuckinghig.tumblr.com/) is terrible, IMO. Does the holier-than-thou author not know how to use the fucking shift key?

Near as I can tell, fees will be high enough so as to make the arbitrage unprofitable.

I believe the mechanism going on here is this:

Big Traders offer to buy at $10.00 on Light Pool. Their offer sits there, and gets filled slowly over time. Then, for whatever reason the price moves, and a bunch of speed traders try to sell on INET/ARCA/BATS at $9.99 (perhaps in anticipation of the market moving down to $9.90). Due to the high fees, they don't place those orders on Light Pool. The market crosses for a little while, no trades occur, and Big Traders get the opportunity to pull their $10.00 order from light pool.

However, the article wasn't clear enough for me to be certain.

Although the tone is perhaps a bit mean-spirited (kind of funny), I have to say that I agree with most of the points readthefuckinghig makes.

Critique is important, not immature. Despite the fact that the blogger in question comes off as a real asshole, he makes real observations about specific details which wouldn't have been so ugly if the designer had just read the human interface guidelines.

If something sucks, I think it's better for someone to say it sucks anonymously than for nobody to say anything - especially if they're citing details that can be fixed!
Here's how it works. When I say:

class Kitty {
val purrVolume: Int;
}

What Scala actually produces in Java bytecodes is something like this Java equivalent:

public class Kitty {
private int purrVolume;
public void setPurrVolume(int purrVolume) {
this.purrVolume = purrVolume;
}
public int getPurrVolume() { return purrVolume; }
}

Later, if you decide that you need to change it to do some special calculations in the getters and setters, you can add that to the Scala code. External users of the class will not need to be recompiled, because under the covers Scala was never actually exposing the public member variable.

"when you don't critique you just make shit" - me
I have no evidence, but I suspect most textbooks are written by tenured professors for precisely the reasons you've outlined. I would submit that these people (not untenured assistant professors) are the most qualified to write such books. I attribute the fact that most textbooks are terrible to Sturgeon's law (90% of everything is crap), so I don't think changing the incentives will increase the proportion of good textbooks, though it may increase the absolute number of such books.
I wonder how this is different from, say, Posit?
