Just start what you like to do.

I don't know a lot about math (I still don't) but I always wanted to write a 3D render engine. I also was afraid of the complexity. But then I figured I didn't know anything about it's complexity because I never tried.

So I started with Processing and wrote an photo-realistic ligh-tracer. Very slow but very very fun. Then I wrote a multi-core version which was a little faster. Then an path-tracer which was faster. Then an exporter for Blender. Then I ported the project to Java.
Is it as good as current render engines? No! But I don't care because I learned a lot and had a lot of fun.

Then I liked to have a CNC router. But I could not afford one. So I just built one and it worked!

Moral of the story: just do it. You will fail sometimes but who cares? You will always learn a lot.
When someone makes what I perceive as a thinly-veiled cry for help, I tend to ignore whatever rules there may be and do what I can to point them in the right direction towards getting some. The guy registered the account to write that.

You don't need to be qualified as a mental health professional to recommend psychotherapy. If a man here complained of symptoms that made it sound like he was having a heart attack, we'd all tell him to go see a doctor, and to me this is no different.

And although the wife may need a psychiatrist and medication (I assume this is what "treatment" means), I was writing to the husband here who in my non-professional opinion needs help of his own, simply by virtue of being in the relationship with her. And for this talk therapy may be enough. (Obviously patience and luck are nice.)

But in that case your word "disruptive" is so broad as to not be very useful and we already have words that mean this.

I've been around long enough to tell you that when an employer is judging you based on your education, this company is so boring, most probably run by academic heads who will bore you to death.

To the individuals who are defending Einstein's behaviour towards his wife, I'm sorry to inform, you'll be ripped off of everything you have in a messy divorce. If you really think that's the right way to treat a person, please do a favor to humanity, marry your hand.

Now that aside, looks like Einstein was human after all. And one full of behavioural defects for that matter. He could've handled that in a much more civilized, and I dare to say, adult way by just having a honest conversation with his wife.

It's very easy to explain your goals, and why you need cooperation from your family to achieve them. If you can't, you have deeper problems than not being able to work properly.
Also consider using the electrum client. It uses remote servers for the blockchain, so you don't need to download and sync with the network, while you keep the private keys for your wallet, so you don't need to trust a remote service:

It also generates new addresses deterministically from an initial seed, which you can write down and keep securely or remember in your brain, allowing you to recover your entire wallet if you lose access to your computer.
similarly, I expected a lengthy discussion of how water transport is more efficient than ground one in terms of pollution and energy consumption (I don't know if it is, I'd reckon it's not) and cities would be building water canals everywhere.
Point made - but do you really believe that halving the investment is going to change the level of drama involved? What is this - a shout out to Biggy's "mo money mo problems"?

Surely, we can respect the complexity of founder relationships, and yes, at times their tenuousness - and not trivialize them as matters that can be solved by making it easier for a VC to write-off the investment. It just feels like an aspirin for a different problem...
Much of what they do has been mandated by governments at various levels, particularly the diversicrats. The Dept. of Education can force universities to cope with a whole new layer of bureaucracy without any change in the law by making student aid contingent on compliance.

And some of it is just featherbedding. When the University of California hired Denice Denton as the chancellor for its Santa Cruz campus, one of her conditions for taking the job was a tenured appointment (with a $192k salary) for her partner. I personally know two other people who got their spouses university jobs this way, so I think it's pretty common.
That's unfortunate. For some reason that reminded me of high school. The AP English teacher was notorious for being considered almost crazy. Her son was a classmate of mine too and one time he decided to flip a compressed air can upside down during class and spray his own arm.

It was well-known that your performance on class work meant very little, and your only opportunity to get a good grade was to bet on the extra credit "opportunities" that arose towards the end of the year. Basically, it all depended on how much she liked you. One girl gave her a ride to the airport and her grade miraculously jumped to a 4.0 after nearly failing every assignment.

She also happened to be the chair of the AP committee, and tenured. It wasn't until well after I graduated that the school was finally able to do something about her, which amounted to having her teach non-AP courses and removing her from the committee.

Few quick tips:
Who are you? What company runs this website? Who are the founders / their background, previous projects, what type of support they bring to this website? what guarantee is given to users, who is already using this app, what does he / she say about it?

Also, how about using anything related to money in your logo?

Cheers,
Since this meetup is the first of many to come, I plan on using this as an opportunity to meet, greet, and strengthen the community.

I'll talk with people about formats and perhaps send a survey out afterwards. I'd like something that really helps the community without people ever feeling like something is being sold to them.

The meetup should be pure, constructive, and hopefully everyone can grow a little more because of it.
awesome comment ! gj
I don't mean to sound forward but what's your background? What's your experience in mobile payment? It's hard to convince someone to put credit card info without giving much info about the company.
Cool. Well I did do something recently that was a lot of fun, and not a little useful: I was annoyed with D3's opaque API and wondered if I could do better. So I wrote a particle system in mostly raw JavaScript - and actually, the code looked (and looks) a lot better to me. I even did some quirky things that ended up being useful like storing velocity vectors in normalized polar coordinates. It only took a few hours, and was quite fun to do. Not quite an operating system, but still. :)
You know after reading the comments on here I was expecting something really horrific. It was pretty short and not all that ludicrous when the time period is taken into account.
I've seen it work on a few sites, like AnonymousAds, but yeah it's not a 1:1 mapping
I was actually considering the current funding situation a part of the incompetence since it goes against the point of having elected representatives. But yes, with the current system it is both the incompetence and sluggishness that is saving us right now.

This 4GB space is evenly divided into two parts, with 2GB dedicated for kernel usage, and 2GB left for application usage. Each application gets its own 2GB, but all applications have to share the same 2GB kernel space.

How to build an ACID compliant database with only 24 bytes of mutable data?
Bombfello - a 500 Startups company
"250%" was of course hyperbole
What a horrible way to argue. So the thought "the evidence might not be sufficient" never comes to your mind? Uncritical thinking like this ("knee jerk reactions") are one of the banes of humanity.
What if I told you that the new Event Store (OSS geteventstore.com) is an ACID compliant database with only 24 bytes of mutable data? This session will look deep inside the Event Store and architectural decisions and trade offs made in the development of it.
Yeah, sorry - I just couldn't find any time to write an online version. Will do it as soon as possible.
That's why Flipboard + Google Reader is such a great combination.
I agree with you in every point, but don't worry. Laziness is part of the human condition, and in order to properly learn how to program one must be able to overcome that. Most people are not able to do this.
Agree with you. Otherwise, it was totally puzzling to me a simplistic, judgmental view calling him a jerk as a top comment.

Don't know how many people have been married a long time here (i.e. > 10 years). Looking at the responses, it seems to me not that many.

Thankfully, my marriage is several orders better than his was. But still I can perhaps see where the conditions are coming from.

Just to take an example - C(3) - you will leave my bedroom or study immediately without protest if I request it.

I can see that for whatever reasons any fights between a husband (who works from home) and wife start when the husband is nicely all set to begin the day's work. It may be over a trivia discussion (perhaps because the husband has some work related frustration) or it could be the result of something building up. Now as a husband who is working from home, does not even have the choice to go to work elsewhere, in such a situation. And the argument/discussion/fight won't end until one person leaves the place. And countless hours can get lost, for a trivia thing.

That wouldn't be better. Intercepting the decoded movie is trivial either way. Finding the encryption scheme was just a fun exercise and discovering the random string (even if it isn't "RANDOM_STRING") once you have the decrypted copy is trivial as well.
Unfortunately, it is pretty common. One school at the university I attended wanted to really hire someone, but his condition was that they hire his wife. They didn't think she "fit" their school so they asked around at other schools. Another school agreed to hire her since on the surface she seemed like she'd be a good addition. To this day, the dean looks back on that and regrets that decision.
The position of women in society in 1914 is in no way comparable to today. We have come a long long way since then, and we still have a long long way to go.

Cultivated men are still jerks today, as a general rule. It's just that we are too blind to see (just like Einstein was in his day) that. Give it until 2110 to tell you just how much.

In 1914 it was totally normal for women not to have the vote, not to have a say in the family finances and to be given consideration only after the sons in the family (but before the daughters). They were not considered capable of higher education (exceptions allowed, sometimes these dressed as men to get around the limitations) and so on.

Cultivated men made those rules and whole pile of others, and decades of erosion by activists and others have restored the balance. Partially. Einstein was - as far as I can see here - not much different than what I know about how life was back then in general. Plenty of his peers would have done much worse than this, and only an extremely small (vanishingly small maybe) portion of society would have done much better.

The fact that we have Einstein on a pedestal today does not mean that (a) he wasn't human and hence bound to make mistakes and (b) that he wasn't a product of his time.
Probably not so much stupid, as ignorant pressure from above, apathy from below, and Marketing off in la-la land selling fantasies. "Lets build something that compiles and ship it, fuck them if it doesn't do as advertised, how will they know?" thinks the programmer.
Since this is an HTML5 App made in Phone Gap it should be possible to have an Android version shouldn't it.

I have, however, balked at the enormity going from the kernel of something to the whole completed thing suitable for commercial release.

There's two kinds of fear; fear of the unknown - where you may learn to wade in anyway - and the more awkward fear of the known. The latter, if you believe the project's basis to be questionable, can destroy motivation. It made me quit my last job.
Fair enough. I made a reasonable but wrong assumption about what kind of business Dan would be talking about.
Hi! We are two engineers with 5 years experience working for companies such as Mastercard.

While we have no concrete experience in mobile payments, we have a good idea of the current state of the payments landscape. We are developing PaySimply on the side now and this is mainly a market test. We will be using Stripe/Paymill as a payment processor in this test, so everything is secure and PCI compliant. Should we include this in the landing page? We wanted to keep everything as simple as possible.

And no problem for sounding forward. It's best to be as brutal as possible :)

It must have been really hard to clean up the room and prepare three meals a day. I wonder how the women of the time did manage at all? Clearly the asian child laborers should let themselves be inspired by their example.

I don't really understand the fuss. At the time it was a normal arrangement in marriage for women to take care of the house. That arrangement in itself is not belittling to women, it is simply division of labor. Household chores are not less worthy than other labor (if you believe they are, see what feminism did, apparently it belittles women even more). The letter says nothing about his wife not being allowed to pursue other options. Even today some people voluntarily choose such arrangements. And it is merely his conditions, she is free to not accept them.
How the U.S. planned to blow up the moon
Thanks for the tips Wajeez. A few of these points are addressed in reply to donbizkit's questions.

For the support: we are definitely supporting this project for the equivalent of a full time project. We guarantee that payments are processed within 7 days (since we are using Stripe for now). We have a select group of friends using our Android app and they love it. We use it almost every day, for reasons listed on the PaySimply website. :)

Should we include testimonials and guarantees about the product?
Reccurent python testing
The rising prevalence of youths who have smart phones makes location sharing apps like this a great tool for parents letting their kids be more independent. That's just one use of this app that I can think of. Several other commenters here have already pointed out great uses: caravans, search and rescue coverage, etc. so I will not try to add on to that. Overall, it's well made and deserves to become a staple tool for live location sharing.
What about privacy issues?

Vancouver's transit authority has been discussing the possibility of replacing the bus service to Simon Fraser University, which is on top of a mountain, with a gondola, as in heavy snowfall conditions the bus can't handle the roads. The main criticism of the scheme has been from property owners that would be under the gondola line, as they would no longer have any privacy in their own back yards.

Similarly if one had a downtown scheme, there would be the possibility of a full gondola moving by your 10th floor window at all hours of the day.
What I'm implying is that a lot of Windows developers don't have a choice. It's the standard issue computer they're given. Maybe they work for a gigantic company with a fossilized IT department. Maybe they work for the government. Either way those kinds of organizations are not running Linux or OS X or Chrome OS. There is a very strong bias towards Windows because of that.

If you subtract that quotient from the general pool of "Windows developers" it becomes much more of a fair comparison.

Yes, there's useful things on w3schools, but like picking through a trash heap full of rusted bicycles and used syringes, it's a dangerous expedition. You might pick up some awful bad habits along the way.

If they stole data from 100K bank accounts using SSN generator and then sent those to the press - yes, probably. Since they instead accessed their own account to which they were authorized to connect anyway - no, not right.

RSS didn't fail because it was too nerdy, it was systematically shunned because it has no DRM.

Systems like newsstand and Google currents seem nice because of their ui/ux, but that's only because its so hard to compete with such giants that have relationships with giant content creators who want surgical grade DRM.
WMP has not changed one bit in Windows 8
What would such an app provide, compared to a normal ebook? I guess the point is simply to be able to get paid via the app store? If so, it seems the wrong solution to me, the app store should change instead of people having to create clunky, temporary workarounds.
It would, however, increase the quality of the offers. I'd go elsewhere if I had to make some sort of effort to hide what may as well be spam.
I was curious if this was secure. Apparently you are trusting the server you retrieve blockchain information from, and could be defrauded if that server is compromised:

Fair enough, but honestly I think this kind of boring work is on its way out. For now it's shipped to developing countries, but eventually I think this will be 100% robot work. So maybe not completely obsolete globally, but on its way and certainly obsolete for the jobs that most HNers think about.
This is good news for everyone.

To have real good traction it must be easy to develop the nodejs standard library on it. If this happens, well, it would be pretty awesome. How are they going to manage the async structure for calls to other JVM compatible languages?
>I haven't met a DRM scheme that doesn't achieve this purpose backwards

Steam would be a good example. It is DRM in the sense that it prevents people from simply copying the game folder anywhere, and it is more convenient than pirating (at least most of the time) with the advantages of things like pre-loading most of the files before the release date, and offering fast servers from which to download your game.
At least you admit that your title was link bait.

It would be certainly more efficient to actually simplify many of the obviously overly complicated "formulas" there. Just for the sake of argument, you achieve the same "effect" of sin(t)cos(t) with a simple sin(2t) (ignoring the 0.5 multiplying the sin that made the amplitude of the movement unnecessarily small).
The problem would be verifying that the people are real, they have the claimed illnesses, they get the claimed treatment, it's the right treatment, they ask for the right amount, have the claimed outcomes and checking where remaining money goes.
Glad to see two big dogs from 37Signals calling for this a day apart from each other. www.pen.fm is actually moving straight into this direction as a platform to allow self-publishing of all sorts of mediums. Super-clean and perfect conversion is a hassle, but if we can track/mark each component to begin, everything regarding styles and rendering becomes so much easier to control. Currently we're on stories and going into manuals, but I can see magazines being the next hit. :)
From what I understand, knowing somebody's name, SSN, address and DOB would allow you to impersonate him/her at 90% of places. In 90% of the rest, they'd require some password but if you sound convincing enough and desperate enough and claim you forgot the password, they'd give you some information they're not supposed to in exchange for the pieces from above. SSN especially is treated like it's super-secret even though practically everybody asks you for it - banks, employers, car dealers, credit cards, lenders, etc. Government loves to ask DOB for some reason like it's a big secret - even though looking for congrats of anybody's facebook page allows to know DOB for like 90% of people.

In general, this whole system does not collapse only because overwhelming majority of people are honest and don't even think about cheating it. Which I think is good, but still I am a bit scared when I think about how fragile it is.
Nikon D4 Battery
I had a quick look at the jobs offered on the website and I found those as example:
WordPress template: budget 12 BTC (~115EUR?)
PHP: add more currencies to BT converter site: budget 5BTC(~50EUR?)
DE to EN translation: 3BTC (~30EUR?)
(conversions are very inaccurate, I just wanted to get an idea)

My question is: is there something about Bitcoin that I am missing that would entice people to work for such low rates? If someone came up to me and asked me to do any of those jobs for those EUR rates, I would decline unless they are either very good customers of mine or I really fancied them.

This is a serious question, not criticism. I'd like to know whether there is an allure to Bitcoin that I'm completely missing that would make people agree to work for less "real" (i.e. not-Bitcoin) money.

Thank you.
You can immediately exchange BTC for USD, so the volatility of BTC truly isn't a great concern. There's a very small chance that you could receive BTC, and when you are not paying attention for a day or so there is a sudden sharp change, maybe -1/3 max realistically, in BTC value. The move could always be to the upside too. I think we'll have >$100BTC within 2 years.
I actually prefer not to link my HN account to an email. Do you mind if we just discuss it on here or some similar format?
