The touted benefits of epoll are mostly bullshit, since it was advocated as being O(1) and frequently mentioned as being O(1) and always faster than poll by others. In fact, right after mentioning that I thought epoll wasn't faster the first thing people said was it was O(1). Every person I talked to said it.

I have evidence that contradicts both of the main assertions of epoll, so until someone comes up with counter evidence I can safely say that epoll information is bullshit, and my argument is nothing like a straw man.

So yes, it is bullshit, and if that offends you then awesome. Because nothing's worse than blindly believing some load of crap when you could have a better understanding of what you're doing.

Overall, the problem (as he sees it) is that you won't have a business because you won't have quality photos on the site (because you'll have "hobbyists" putting photos on there). Maybe just find some forums / blogs that cater towards "prosumer"-type photographers...the kind of people that buy high-end equipment, are really into the art, etc. -- but that might only be doing it for the fun (until they realize they have the opportunity to make a few bucks for doing nothing except submitting their best photos to your website).

As an aside, maybe you can have some kind of rating system whereby photos can be rated by (and only by) other photographers who have submitted photos to the website; photographer-users would only be able to see their rating of a photo (not the aggregate rating), but the aggregate would determine it's place in "top {N} in {CATEGORY}" lists and the price that was charged for the photo.

Anyway, to answer your question...if you believe you've acquired enough domain knowledge to build a successful business, then I think you should go for it...otherwise, you'll always be second-guessing yourself and wondering if you threw a fortune away because someone else told you not to go through with it.

The nuclear industry is best run without competition. See France. The whole energy industry there is like soviet-style centralized economy. This leads to higher costs and at the same time to low safety. France for example brings a lot of nuclear waste to siberia where it is stored just under the sun, outside.
You would never get real costs out of the nuclear complex in France. It all cleverly hidden. Yet they can't even produce enough energy for their country and deliver it. Last winter the power lines in France we almost collapsing. Heating is done with electricity and the winter was long and cold. The whole structure of energy production is very centralized (and not mesh like). At the same time 20% nuclear reactors were off the grid and Electricity had to be imported.

Even for a conventional energy production it is important to have competition. But the big energy producers are getting monopolies for their regions. In France it is even worse: there is EDF and not much else.

Next, the nuclear reactors are not using their heat in any useful way in France or Germany. They are mostly used to heat up the rivers. Which at the same time limits how many reactors one can put at a river. They need lots of water for cooling.
The thing I tried this program, ie not a webapp, that lets you fill in your exercises and your meals and then calculates if you on the right side. It lets you put up 10 week plans and doesnt let anorectics use it.
Should be something like that as a webapp. I think someone did something like that in Arc.

The nook has such little power that to call it "Android Powered" is a gross misuse of the term. Yes, you can downgrade the firmware, root the device, and upgrade it, but the web browser is still god-awful and I didn't see any good third party apps.

For an e-book reader, with the option of playing Chess and MP3s, its top-notch. But right now, the ability to run apps on it is more theoretical than practical.
Exactly, nobody knows because they've been operating under the assumption that epoll is always faster so they never looked.

Now I've got some evicence that epoll isn't faster, and in fact it's a wash at 40% "utilization", which is sort of ridiculous. I'd want people to go and test and see what they get, or at least know the implications so they pick wisely.

Ultimately though, I'd rather have the Linux kernel just fix epoll so it's always faster than poll.
at the end of the day you're still mooching off your friends when you're perfectly capable of doing some job while you look for more work. IMHO, that's not acting like an adult.

Well, these days, I'm the moochee, in your terms. But that's fine, because helping each other is what friends do. I don't think it's childish behavior to accept proffered help when you need it; succeeding is hard enough without insisting that every little gain must be solely due to your own hard work.

There is a business opportunity here. Managing credentials and secrets is (passwords, private certs, etc) is hard. Making that process turnkey, secure and easy would be useful.
Looks good, though open World tab by default. Didn't notice there were other tabs as well.
To be completely honest, I think this is a ploy by RIM to make them seem insanely secure. So secure that paranoid countries want to ban them because they can't evesdrop on their people.

You know jack squat about statistics. That's basically how I summarize your statement. You don't have a mean, median, mode, or standard deviation in your "10% 40%". You don't understand confounding and want to test the performance of poll vs. epoll on file descriptors by testing an entire server. You think science is to use available data, when it's nothing of the sort, and in fact the way you remove confounding is to remove data.

Basically, you're a FUD slinger who's got a beef and doesn't know enough to hold his own in a real discussion about measurement and analysis.

How can you control a class of twenty students without some sort of authority and without requiring some sort of submission?

I realised what she said perhaps at a younger time than her age, maybe when I was 14, but as I have grown I have come to realise that I do owe much to that very system towards which I shared her feelings. Indeed perhaps it was because of that institution that I was able to even think such thoughts, and have such realisation and gain such understanding about such a great picture as an entire institution.

We should indeed find ways to improve our schools and perhaps even find such ways in this big picture scale. But you can not simply condemn this institution through some rhetoric. She says nothing specific and hardly offers any suggestions seeing as she is fresh from this institution and would perhaps know better than more how things can be improved.

And I submit, that she is unaware that she owes so much to that institution and that institution has offer her so much. She might not like it, but I doubt she could suggest that she is not the better for it.

Also, I do not think students are robots. They have plenty of freedom. Two weeks holidays every six weeks of teaching, six weeks summer holidays, then they have literature where they can be as creative as they like, and arts, and music, and sport, and plenty of afternoon free time. They hardly can be uncritical, but they do as they must learn that criticism, however truthful, has a price, especially if aimed at the powerful, i.e, teachers.

Unfortunately, there is no other way but to teach kids maths, how to read, biology, history, the facts and make them memorise them. If they don't remember the specifics, then their memory would improve, which I think correlates highly with intelligence, especially working memory, and they will learn plenty of other things, such as to see the bigger picture as she has. I doubt that without those literature classes she would have been able to, or without those history classes, or...
The psychological challenge of living in space
>That's a great quote. It seems that once a company becomes undisputed champion of a particular area they redeploy their resources trying to find something else to dominate.

Or they realize that their domination is fragile.

Google worried about the mobile space because it was an area where they could be cut entirely out if one commercial interest dominated, even if their product was what users wanted, had the best features, whatever. With Android it's notable that it's intentionally a very "fragmented" ecosystem, and the reality is that any of the vendors have the full right to pull Google hooks right out of the product if they so desired.

One company dominating mobile is a threat to their search business in a way that could completely undermine their entire business model, especially as the mobile space continues to gain relevance. Note that Android did originally target the RIM ecosystem as the original indications were that RIM would dominate.

Google worries about social media in the same way: To a lot of people Facebook is, sadly, becoming "the net". Businesses, from big to small, advertise their Facebook page more than even their own websites. People email and message on Facebook, game, read and post reviews, and so on.

It is a serious threat to search, which of course means it's a threat to advertising: Google's model is built around a long-tail, very distributed web, and Facebook is completely turning that upside down.

I think Google has far less interest in dominating these areas than they want to simply shake things up to avoid anyone else dominating.

We are currently working with a UX expert to help us re-design the look & feel and the functionality of the website, and the issues you bring up have been brought to our attention and will be addressed in the next iteration of the website.

(We currently do have a "How this Works" section on the front page that says "Record Sound, Get SoundKey, Use Anywhere" with an explanation of what that means, but I guess it's not clear enough because lots of people complain about it. Hopefully the updated website will make things much more clear in much less time)

I might buy the End of Science argument, but this would be far from the first time that it has been made, and I'm not sure it really works. Look at computer science; how much of that was or could have been worked out in the absence of an actual computer? And as much computer development was aided by government funding, the commercial imperatives were just as compelling. (Look at IBM's pre-digital computer success.)
If you don't mind me asking - why so long? Our pediatrician recommended my wife breastfeed our son a year. Beyond that, he said, there are no benefits.
Since you're presumably entering the data (i.e., email text) using a BlackBerry device, running an RIM-developed operating system, device drivers and so on, RIM most likely "have" your data.

At least that was how I interpreted it, and it makes sense to me.
Yes, nobody seems to get confounding at all. I'm testing poll vs. epoll on selecting active file descriptors to compare their performance. I'm not testing anything else, not claiming anything else. To then test that with a full on server that has an Amazon EC2 cluster blasting requests with HTTP parsing and serving files would completely confuse the analysis.

You don't measure a specific thing by inventing some full on "real world" evaluation. You test that specific thing. Why is it this simple concept seems to baffle so many coders?

Someone mentioned Montessori schools, which seem to do pretty well. Another along similar lines, but more extreme, is Sudbury Valley schools:
http://www.sudval.org/

Kids are taught whatever they ask to be taught. They aren't divided into classes, they can just wander around the campus asking for help from any teacher they like. If you start kids young in this environment it works really well; kids are hard-wired to learn as much as possible if you don't make it a miserable experience.

Something else they do: every kid gets a vote in school decisions. A kid's vote counts as much as a teacher's. It's like they're teaching kids to be citizens in a democracy, instead of subjects in a dictatorship.

I once read that (iirc) New Zealand used to have horrible public schools, and fixed it with this system:

- Every parent can send their kids to whatever school they wish.

- Each school is directed entirely by the parents, with no interference from government bureaucracy.

- Each school gets $X per enrolled student.

It took about ten years to shake out, then they had great schools.
You could also use a Nabaztag and let the rabbit dance on post-commit.
No really, where is the proof that this is in fact happening?!

Businesses, with current law, CANNOT make donations to campaigns! Only individuals can and the limit is $2,300.

The whole thing sounds very sensational and juicy, but the FEC data just DOES NOT SHOW THIS. See my comment down the page, email me at my username at gmail, I am really trying hard to understand campaign finances.

I'm very much disturbed by the impotence of our Congress, and that's exactly why I keep trying to understand what's _really_ wrong, but I am not about to accept some theory just because it sounds enticing when there is ZERO data to confirm it.
Yeah, 'cause there's no way I'll be able to test a real web server that I actually wrote based on this small test. This is a small test to test one specific thing, doing more would confound the test. Confounding. Look it up.

Incidentally, this is the same test everyone else uses, so if you thought it was bullshit why did you support it when people testing epoll with it were using it? Oh, because they used it to confirm your bias rather than disagree with it.
Thinking about this a bit more, I realize that in the decade I've been in NYC, the majority of the time I've been working with or for startups. On the tech side there are companies like Morningside Analytics, who do incredible data visualizations of the blogosphere. MA was bootstrapped by three guys from Columbia University. Perceptive Pixel was founded by Jeff Han, based on his work at NYU (you might have seen his TED talk). Fog Creek was founded here. Peter Shankman founded AirTroductions and HARO. UrbanDaddy is a block away from where I'm sitting. Foursquare is here and so is Boxee.

On the creative/advertising side of things, where do I start? The company I'm currently at was bootstrapped by three guys back in 2006. Now we have 25 employees in our NYC office and satellite offices in Amsterdam, Stockholm and Sao Paolo. There are a ton of creative start ups in NYC. WDDG (MochiMedia, while based out of San Fran, was founded by Jameson Hsu and Bob Ippolito, both former DDGers (hi Jameson and Bob)), Big Spaceship, Barbarian Group, Enjoy User Experience (whose founder was co-founder of Kioken)...

This stuff is off of the top of my head; I don't even hang out in the NYC startup scene. There's plenty of stuff going once you get away from Wall Street.
Why did the US Government claim Kindle violates civil rights?
Ask HN: Want to test the market/idea before launch, but how?
We are working on web app for restaurant/cafe/bars and want to test the market.

What we want to achieve?
As our product is still in development stage and take at least 30 days to come in beta stage, but
We want to show our product/idea to users and bloggers through some kind of screen cast with voice, so that they can have idea about what is product all about and how it will benefit to uses business.

Our secondary objective is to get beta users.

Benefit to user/blogger
1. Get discount on release.
2. Blogger will get coupons so that they can distribute among their readers.

What we did so far?
1. Create the list of potential uses [company info, contact email etc.]
2. Created the list of forums, blogger.

Our questions
1.	Is this a right approach?
2.	How we can create awesome screencast with great voice without full product.

Hoping great answers.

Any help is appreciable.
The 99Designs logo is a serious downgrade. It's washed out and the type choice is boring and immediately forgettable. Not having the little bingo card in the logomark is also a mistake IMO.
There are two types of negative feedback. One is from people that are attempting to predict the future, and the other is from customers that actually use a product. You should only trust the feedback of customers (but not necessarily their suggestions.) You could get a better understanding by allowing a small subset of individuals to use a clean beta version of the product. That would let you know what to fix even if you do not know what to abandon.
Testing this on real live servers is confounding. Man you guys really don't get this. If you want to test epoll and poll over file descriptors you test that. You don't test a billion other things in a network server. That confounds your results.

But what's really amazing is this is the test the proponents epoll have been using for 8 years. Where was your objection back when they were using it for that?

I have a bunch of "unique" features that most of them nobody seems to use. Listings can be commented on by other people. Listings can be closed so you don't get continually spammed after you sold your book. You don't need to login to browse listings or message the listing's owners. You can upload an image of your book to your listing. You can search listings by course code. You can add a "Request" listing instead of the normal "Sale" listing. You can add additional details to your listing. The website is also compatible with Google Chrome. You can clearly see how long ago the listing was made. Listings are sorted by time submitted by default.

None of the features I've mentioned are available at Textbook Exchange. They can't even make the website compatible with chrome, blaming it on:

'Having problems clicking on the "more" button? If so, you are probably using the web browser Chrome.
Textbookexchange has been around a long time - way before Chrome existed, so we're still sorting through this issue.'

There is only one thing left that their site can do my site can't - send an sms to the owner of the listing. I will get that up as soon as I have enough economy of scale.

As you can see, because textbookexchange is a website that isn't even competent enough to maintain compatibility with a major browser, I don't think they deserve to be the largest textbook classifieds website in Australia. They hire 15 full time staff to put up a piece of <insert expletive here>. I can do better with just me, and I haven't even graduated yet, let alone have had any "software engineering job experiences".

Well, long story short, every time I tried to contact a book seller from their website, the book is sold already but the listing is still there. I'm just one really pissed off customer. :D

Basic social norms also involve not saying ruthless comments you wouldn't say to my face.
Thats actually what I meant. Not necessarily that job boards are the "Hot new thing", but that they are the "thing" that is easy to get rolling and always seem to attract listers.

To the people adding them, there isn't very many reasons not to add them.
fixed it. there was some invalid tag.

"to address the growing crisis in K-12 computer science education"

As someone who never saw a computer in any of his K-12 days (long ago), I wonder how one measures the growth of the crisis. I suspect that if the schools could address writing and mathematical competence the students could more easily master computing either on their own time or in college.
Normal people like poor twentysomething males who are habitually adblind, value only digital content, and steal all the content that isn't nailed down, or normal people like forty-something females who make purchasing decisions related to the website niche for households with $80k+ average incomes, where goods responsive to the needs of the niche have little branding and 90% plus profit margins?
I'm shouting you down because you're a FUD slinging troll. Very first thing you did was immediately reply to every branch of the comments with your agenda. I actually have no idea what your problem is, since I'm just presenting some information and working on my own software with it, but you've got some weird "epoll religion" you like to spread.

So, consider me the Richard Dawkins of epoll.
Not just you. But I'm not a teacher looking to make bingo cards, so my opinion might not count for much.

The Sudbury Valley model is definitely an extreme as far as the freedom & responsibility it invests in its students -- the school decisions you mention include expelling students, whether to rehire each teacher every year, etc.
Corporate email is encrypted between the Blackberry device and the corporate mail server. RIM has no access to it.

Consumer email is encrypted between the device and RIMs own servers, therefore they have access to that data, just like any other ISP-hosted mail.

BlackBerry Messenger traffic could be encrypted device to device, but I don't know if that's actually the case.
