As someone who moved to the US for work, one important benefit of 'the certification aspect' is that it'll open up travel opportunities he'd otherwise struggle with: most work visas require a degree, sometimes 'or equivalent experience' but that's harder to demonstrate. If he actually wants to immigrate somewhere the degree may also provide points for that.
Education is already structured like game with every every feature of gamification like points(scores) and grades(levels) and Leaderboards and so on... But it is a very boring and badly designed game.

Playing a physical game like football and maintaining a good physique for winning a football game seems a lot more fun than exercising to not be sick. Same thing could be said about khan academy. Would it not be awesome that a student can learn 50+25=75 without having to pull out an iPhone to calculate the same... Does it matter whether he did it for energy points or self improvement. A student with good "skills" will likely find it easier to navigate more meaningful content in the future like graph interpretation without even noticing that "the algorithmic skill" came in handy. I totally agree that something like KA is not a solution but just piece of the jigsaw puzzle.

One of the students of the stanford online classes ended up making a cellphone powered self driving car by going through the online class. While the student got the basic framework and ideas from the class, he must have learned a huge amount of stuff putting it all together. Learning is very human no doubt. But it can happen in the minds of the learner. Thrun or Andrew Ng do not need to actually talk to the student by standing a few feet away. They just need to empower and inspire students to work on awesome projects. The students can learn by themselves and each other.
Long Live the GOTO Statement
Right, it's totally understandable that you would tune mechanics in order to keep the addicts paying.

Don't expect not to get judged when you work for those pushing the envelope in this direction though.
That's an interesting point. Why do you think it is easier to get distracted while reading a Web page than while watching a video? Do you think the argument still holds when you're viewing a page in full-screen mode?
Except no one brought the subject up. You're blurting out your off-topic opinion/problems/disagreements just because you felt like it.

Privacy laws in most Western countries outside the US (at least all of Western Europe) are based on the principle that you own your data.

The rest simply follows from that. If you tell Facebook to remove your data, they are, within reason, obliged to honor that request.

Now that photo may still be out there if it has been copied (of course when then come into the realm of copyright and such), but Facebook should no longer have it in their dataset, let alone be publishing it.

The privacy angle isn't about the photo being public, it's about Facebook having it in their database along with all the other stuff they have on you.

This is why American companies like Google and Facebook tend to run afoul of European privacy laws: even if the data they collect comes purely from public sources, doesn't mean they have the right to collect, and especially collate it. At least not in the European concept of privacy.

I am not trying to figure out all the variables. Also I am not spending too much time trying to figure out "how to make it on HN". I can just go back to doing the same thing I used to before--post on HN, share the post with friends (probably post on Facebook or Twitter), and it will go up on the front page. Again, I'm not so worried about this.

Here's what I think: I think Hacker news is the only influential site that functions as a place to help small but interesting projects get discovered in a democratic manner. You could just email about your startup to Techcrunch,Mashable,The Next Web, et al., but you still need to pass through their editorial filter.

What I find intriguing about Hacker News is that the filter is democratic (and focused on Startup culture), and relies less on social proof. A lot of companies get multiple coverage on larger tech blogs because they have funding from famous VC and angels. With Hacker News, you don't need social proof. You just need a good idea and good execution, at least this is what I want to believe.

As I said, for "the people in the know", HN works differently than the rest of the world. A lot of people post on Hacker News "hoping" to reach the front page, but for example the guys at YCombinator (or entrepreneurs who are their friends) don't need to worry so much about it because they already have enough karma to push their post up to the front page. It's almost taken for granted.

Well that's how the world is run, and that's why being in Silicon Valley is so attractive, but I think Hacker News provides a platform that's larger than that, and just wanted to know if any counter examples exist: Just a small startup out of nowhere posting on HN, and getting huge traction.

Thanks to those of you who give Facebook the benefit of doubt. I don't work on this particular system, so I'm not qualified to discuss any specifics, nor do I speak for the company. I can say this though: People @ Facebook do care about these types of problems and work to solve them. I'm not some new grad; I've worked with large systems for a while. The scale is hard for me to comprehend. The systems I do work with illustrate very well that nothing is as simple as you think it might be and most of the obvious solutions get tossed out the window because they won't scale.
That's fine, I can understand that. Sometimes I just get a bit perturbed by questions along the lines of "what's the best way to get on the front page of site x?"

I get upset because, from a marketing standpoint, it isn't even that important or advantageous. You're far better off targeting sites directly in your vertical than aiming for exposure on more general sites like HN.

Wasn't btjunkie used primarily to violate copyright?

If so, it seems you are mistaken about the outrage regarding SOPA. The outrage was not defending our right to free movies. When Megaupload got taken down I started seeing all these posts that seem to be under the impression that the Internet had rallied around the right to get everything digital for free/cheap against the creators' wishes, which is not the case.

If someone wants to pay you 10 grand that's his decision. I don't ask for a credit report before I take money from a customer either, so for all I know I've taken money from people who couldn't afford it. I don't think it's your job to predicate every transaction on your customer's financial/emotional health.

However, I do think the closest moral analog to running a casual Farmville type game is running a casino. If you're fine with running a casino, I'm not trying to stop you.
Thank you for the feedback.

For the Mongo installer - I really, really, really wanted to install it with one line of code, instead of writing 100 lines bash spaghetti, but that's not possible - it works on some distributions ( it works fine on Ubuntu 11.04+, but I always had problems with Ubuntu 10.10 and CentOS 5.5 ) and it doesn't work on others.

The problem with the logging are not application logs in general. I started working on that module, not because I didn't like the way I store my log entries, but because - I wanted flexibility on a program level. Every programming language out there has a diverse set of datastructures, but the logging modules are always limited to strings and levels. So you can't really "personalize" and "humanize" your log entries and also - you have one additional step - to convert the log entries to strings. And that depending on the language is between 1 and 4-5 lines of code. And these lines really add up.

I fixed the OS detection script, thanks for that
Tell HN: Thanks
I've only been here for about a year, but I've noticed an uptick in negativity: flame-wars, Reddit-hate, and invocations of Eternal September.

I just wanted to say that HN and the HN community have not only given me some great opportunities for genuine, good-faith, civil discussions on topics as controversial as affirmative action, Apple, and Google, but they've also given me the encouragement to work hard enough to get some essays published in the Atlantic tech blog.

And what's more: I quit my soul-crushing government job and I'm starting my new one at a local startup tomorrow, in no small part because of HN and the HN community.

Though I've learned something new every day and gotten a ton of perspective on tech, entrepreneurship, and life, I probably won't be able to spend as much time here. But I really draw a lot of value and I'm grateful to PG, the moderators, and everyone who contributes valuable stuff!

Thanks!

Tips to Optimize Your WordPress Site
The problem with asking for reputation points in exchange for services is that you're really just asking for payment. A lot of the things people do that deserve payment would be free with nothing asked in return

The system should also be anonymous so that it's not even possible to get points as payment, otherwise the Donald Trumps of the world would pull some marketing trick or make some system to get all the points and all the money, assuming it's ever worth something. We want a system that would have put mother Teresa or the google of old on top, just on their ability to reach out and positively influence so many people
It's worth noting that there is some consensus amongst sociologists that money and people are the two primary forms of power. (And I do mean primary: all other forms of power derive from them.)

It's also worth noting, in a much less constructive but perhaps more interesting discussion, that "money is power" presupposes a power structure that allows money to exist. Hmm...
I found this fascinating and a alternative view to my own held beliefs on alcohol.

This really seems to be a better way at addressing social policy - yes beyond the genetic disposition to alcoholism there is definitely a cultural molding that determines behavior.

If the expectation of behavior (say from holywood and tvland) is a major factor in the behavior of those under the influence rather than say the quantity or concentration of ethanol, maybe humanity can address this by how popular culture programs us?

Free MP4 to iPhone Converter – How to convert MP4 to iPhone on Mac

That's a good question. I would think there are more people with serious gaming addictions out there than there are people rich enough to spend more than $10K on a game without it affecting their economy in some negative way.

If you really want to find out if targeting these users to maximise profits is harmful or not, I think it's a good idea to ask these spenders, perhaps have them take a survey. If you don't want that, I'm pretty sure there's research out there on gaming and spending habits that can shed some light on the question.

[Edit: I see that you sell through iTunes connect, and I don't know if Apple permits you to have anonymous user surveys in you app. Even then, I'd guess that you wouldn't risk your highest paying customers reconsidering their gaming habits by asking them uncomfortable questions in a survey. Given that, I would think actively looking for published research papers would be a good idea.]
Your assumption there is no law against piracy in Russia is false.
Russia is not a great idea, our gov took torrents.ru domain away without any trial as well. They are not so active as in USA, but since Russia is on the way to WTO, btjunkie wouldve been closed rather fast if it would be demanded.
Interesting. I was trying to think of any controversies due to "heretical" thoughts. We really haven't had any. (So maybe you are right!) We have our nerd-fights about say, rspec vs minitest, or estimating techniques, but not much beyond that. All of us lead pretty well, when we need to, and follow well when someone else is leading.

Regarding diversity, I actually think we're pretty diverse. Our 8 developers include:

1 Indian, 1 Palestinian

1 woman

2 overweight but not obese

2 introverts, 1 strong extrovert, 3 mild extroverts

1 M.A., 1 M.S. working on his PhD. 2 high school drop outs.

2 Textmate, 6 vim

1 under age 30, 3 over age 40

1 ex-con, 1 former jazz musician

4 married with children

3 prefer dogs, 4 cats

Apparently, though, we all like to mountain climb.

All of the "4096" results have exponentiation as left-associative, despite the common conventions that exponentiation is right associative.

Seeing the example really makes me wonder why that convention exists, and also makes me ponder whether having variate associativity is actually a good idea after all. Especially in languages like Scala, where you can change the associativity of your binary functions through function naming.

Though I can see why things like the cons operator "::" make a lot of sense.
In this analogy, somebody tried and failed to make knives illegal. Meanwhile, the government has gotten more serious about going after those who willingly supply knives primarily to those who will use them illegally. And one such supplier has ceased business volutnarily
If your biggest problem is paying a $2 Billion tax bill on your $25+ Billion in earnings then you're doing ok.
This is a nonsensical comparison. Considering that the language chosen requires fairly verbose code (everything from a minimum 14 bytes for a function declaration to longwinded API names, eg "fillStyle" that takes a string with another 7 bytes of decoration[1]), this is exactly what you'd expect. The challenges presented by the particular language and execution environment are a large part of the entire point of these exercises, they aren't a failing.

So, good work, you've declared all such competitions with languages less terse than assembly "scary" and no doubt a harbinger of some slippery slope. I hope there aren't any competitions with ISAs smaller than x86, or your world really might fall apart.

[1] 'rgb(,,)'. converting to hex might be a good size optimization there, actually, but it would still need a '#' and be a formatted string.
Enjoyed the article, but how is this sufficiently different from say NewsBlur?
True, if there's any way to game the system or brute force your reputation, it's going to cause problems. Digg had issues with power users getting paid to post, and even news aggregators like Reddit and HN can be abused if people have their friends upvote submissions. People like sharing things they find interesting/important or have an emotional response to, as twitter has proven.

If you search a business' name on twitter you'll get some sort of consensus on what people think about it. This stuff isn't aggregated in a way that is really helpful, though. That's is what my startup is trying to solve - http://moodstir.com. When a company like Netflix pisses off its customers and they are willing to tweet about it, others considering using the service ought to be able to find out the general emotional stance customers have towards the service.
As a Django developer/sysadmin myself, I'd be very interested to hear more details about how you deploy.

This is exactly why when ever I need to do any sort of math in a program I make sure to put parens around any single operation. Even 2*2+2 gets the treatment because god knows there have been people who screwed that up.

> Also, indoor flying means no GPS.

Correct. However, indoor positioning tech will likely come of age in the next 12-18 months driven by indoor mapping and navigation. Once that becomes commoditized, it'll make positioning a little aircraft like this in the x,y plane of a floorplan doable without dead-reckoning. From there, you could probably do some crude lidar to measure the distances above/below the craft to the ceiling/floor.

Firstly, if you have any suspicion of having sleep apnea, I highly recommend getting a sleep study[0] done. I was diagnosed with a moderate case of obstructive sleep apnea after suffering from it for several years. I feel fortunate to have discovered and treated it at a fairly young age since it results general misery and is believed to cause heart attacks and strokes if left untreated.

I found no noticeable difference in my ability to recall dreams from the night before, or the length of dreams I experienced between using CPAP or not.

With regard to sleep patterns, the results from CPAP were immediately noticeable. I found that CPAP allowed me to go from a zombie that needed 12 or more hours of sleep per night to one that only needed about 4. This was not better. Despite really enjoying the extra 8 hours of "waking" time I had each day I was still tired all the time and thus made little use of the extra hours. I now sleep between 7 and 8 hours per night, I feel great and I am way more productive.

What is the "average comment tree"? If one has a forest (a disjoint union of trees), how does one 'average' them? What do the tooltips mean? It's not clear to me what I'm looking at here.

I think this visualization has potential (I have similar ideas along these lines) but at the moment it feels a bit like "visualization salad".
I think there is a middle way in everything. For instance, you can run a game company without targeting serious addicts. You won't make as much money, but maybe you'll feel better. You don't have to go insane, though.

Hi All,
Introducing to you bakarbox.com where people can share their funny, crazy, and weird experiences ( what we call as "bakar" ).

Filled with features

Voting, Commenting, taggings, profile etc..

please have a look into and it will be great to have your suggestions/ feedbacks (weird ones too).

Clearly its not aimed for any business/startup purpose or something like that but purely for fun and experience sharing.

i know its much similiar to many other websites But i tried to make it clean and since it's my first attempt so love to hear what you feel about it.

Love to listen what more it can be?
I test my app with people.

Scripting out unit tests, integration tests, feature tests, regression tests is good, but there's always going to be stuff you miss. I'm not saying you have to hire a full-time tester, but get your friends, family, or other people good at breaking stuff to test your app. You'll be amazed how some people will use (i.e. break) your app in a way you never considered.
It's pretty obvious that these games are just elaborate slot machines. Like slot machines, the companies involved simply don't care about the ethical issues. And you're apparently happy to profit off these activities until the evidence sticks to you. Just like the cigarette companies have always been eager to profit off a questionable business due to "lack of evidence". For shame.
Why is exponentiation associative? This:

4
3
2

You should also try to visualize the 4 smaller and 3, and 3 smaller than 2. Because this is the way it was written for a long time.
