The key word here is "effectively". I am surprised that so many people need this spelled out, but I suspect that many of you making this identical point live in a bubble, far from the world of traditional commercial software development.

Many conventional software business models are unsustainable if you give away source code. Yes, there are always exceptions (where, typically, you have some closely related bit of software or IP you can charge for - think Pathscale with their libraries or Snort with their ruleset), and you can slave away chasing your product around with services until the End of Time.

However, there are a couple things you just plain can't do with open source - one is to prevent people from making builds of your software for free, and the other is to prevent your competitors from free-riding on your research efforts and duplicating your hard work for a much lower cost than it took you to create it. The only way you can prevent the latter strategy is to patent the living shit out of everything, which I also find objectionable. I don't like the idea of trying to prevent someone who independently invents the same idea after me from competing with me. This sounds like honest competition. He or she got the idea by thinking hard about it - not by looking at my code.

Another horrible weakness of F/OSS business models is that, in many areas, there are ridiculous mazes of interlocking patents, often covering many versions of the same thing. Putting your source code out there is like sticking your head into the patent troll's mouth and begging to be bitten.

"Charge as much as they wish or can" is fine up to a point, but you just plain can't, and any attempt to create a situation where you can charge more for the fruits of your labor than these crippled business models allow is treated as immoral.

An invented 'right to tinker' somehow trumps my (equally arbitrary and invented, in some senses) right to be paid exclusively for innovations that took a huge amount of work to come up with until such time as I choose to release them or someone else figures it out - or something better - too.

The (closed source) company I work for is full of grown-ups, our customers are fairly grown-up too :-) and if we are so benighted as to enter into a mutual contract where we get paid and no-one gets to see the source, it's None of Richard Stallman's Fucking Business, or yours.

I'm not taking away a freedom of his because I never would have invented a goddamn thing if I had to build things under the very limited range of business models possible in the world of F/OSS (note: I'm not hating on those models, just pointing out that they are not appropriate for every type of software).
nice insight into what it takes to go from an idea to reality by the author of the Objectify app-engine wrapper himself!

A mistake I’ve seen in the past is that these types of decisions (i.e. which framework or library, should I even use a framework, etc.) are made for technical reasons rather than business reasons. What are your goals? Are you building an app for yourself as a hobbyist? Are you building an app to sell? Are you building a business around your app?

You need a house. You can:

- design your own

- build from someone else's plans and make mods as you see fit ( recognizing that too many mods may compromise the overall plan.)

- buy a prefab “kit” home that you assemble

- buy a mobile home trailer

What should you do? It depends:

- Do you need something right away?

- Do you want to win architectural awards and hopefully be profiled in a “beautiful home” magazine?

- Do you want your home to be mobile?

All in all, I’ve found that each decision has its trade offs. Pick your poison. You will always find reasons why you should have maybe gone another route. “Too bad we didn’t use framework X. It makes problem Y so much easier to deal with.” Oh? And what about problem A, B, and C?

My B2B Company started with MS Access. It got us our MVP very quickly, and our first clients. A good technical decision? No. A good business decision? Well, it worked out pretty well for me.. If I were starting again, (in the B2B space in which I am most familiar), I would probably go with Oracle’s Application Express, with which I could very rapidly build a functioning prototype and even run the business on for the first (perhaps long) while.

One of my favorite pieces of wisdom from Steve Blank is “Most often, business don’t fail due to a lack of technology but due to a lack of customers”.

“The speed of a non-working program is irrelevant.” - S. Heller (in "Efficient C/C++ Programming")

I am unfortunately at work. I usually do not log into HN from work. I am doing so as a curtesy to you. Any other replies I might care to make can wait until tonight.

it feels like you're doing a bit of the same by claiming that everybody who wants to change the world are doing so only because they're projecting.

You left out the words "overwhelming need". It speaks of desperation, which is very different from having goals.

All too often in life I've been happy just coasting along, taking the easy road in front of me, pursuing good grades in earnest, working hard, and making a good living at interesting jobs. That brings me no closer to my goals in life though, that's not my dream.

I have never coasted or taken the easy road. I have consistently chosen the hard road. And please note you are stating that your desire to change the world is a personal need, not really for the benefit of the world, but to satisfy a dream. There is nothng wrong with that. Nothing at all. But do keep in mind conflict of interest: If you really, really want to make the world a better place, it helps to take a skeptical eye towards your own motives. Setting aside my ego so I could do something of real note has been one of my biggest challenges in recent years. I would be happy to discuss it more with you, on hn or off, after I am on my own time and not my employers.

Peace.
I found the MIT Tech Review's summary confusing. I didn't understand the article it was based on fully, but the idea seems to be covered in the following paragraph:

Time-space duality represents the analogy between diff raction and dispersion that arises from the mathematical equivalence between the equations describing the diff raction of a beam of light and the one-dimensional temporal propagation of a pulse through a dispersive medium [17,18]. Similar to a spatial lens that imparts a quadratic phase in space, a time-lens can be implemented that produces a quadratic phase shift in time [19{21]. This time-lens can, for example, magnify [22] or compress [23] signals in time and has an equivalent of the lens law. Time-lenses can be created with an electro-optic modulator [18] or via a parametric nonlinear optical process such as four-wave mixing (FWM) with a chirped pump wave [19,20]. In the latter case the signal wave is converted to an idler wave with a linear frequency shift in time (i.e., a quadratic phase in time) [21,22].

I understand this to mean that the passage of time in observed space can be slowed down relative to an observer, rather as happens when observing a body falling into a black hole.
Yes, I sincerely hope they are for real and not just posturing, and that this will start a new space race.

The fiestastic web design looks really good and its always nice to know that other people think there is potential in the idea.
I feel its a good strategy to have an iPhone app before a website or other native apps
1) I have never said "check out this cool website" but I have said "checkout this cool app" like a million time
2) Its cost effective (for a start up) Running a server requires time, cost and energy where as distributing an app is easy.
3) You are just supporting 2 phones with 2 screen resolutions. It helps in delivering a good experience. You wont have a lot of users saying it does not work on my Sony Ericsson E10i Xperia Mini.
These are just my views and they should not mean anything :P. I am definitely not an expert.
Well, the good thing about both Crowdspottr and Fiestastic is that, unlike classic social networks (Twitter, Facebook, etc), even if only 1 user uses the service, it's already useful for him/her, as all data (events and friends) comes from Facebook.

Of course, being widely used (at least in a specific area) would bring extra benefits and more possible features, but I like that it's useful even to the very first user.
> On the other hand, I do have about four other ISPs I can switch to, maybe that influences it?

Real competition, yes, that is the big influence. Sadly, in way to many locations in the US, one's broadband choices are limited to one or two providers.

If every location where Comcast operated broadband service there were four other equivalent providers of the same service, they would not ever think of cutting someone off for a year or limiting them to 250G/month of up+down transfers. These kinds of tactics are what monopolies do, simply because they can.
What's wrong with that? To protect yourself from copyright claims this should be a normal practice in this crazy world of legal regulations and lawyers disturbing engineers in their work.

Reading, signing, scanning and e-mailing this nice 2-page agreement should not take more than 15 mins, and it's a one-time effort to become a committer. Then both sides are set.

I quit my day job in May to work on an idea. It was a good job, but I simply had to do it so I quit within the week. Since then I've been working at home and it has been up and down--mostly ups :)

Looking at my journal* (personal work journal), it went like this: Tuesday: came up with idea. Wednesday: had dinner with previous startup CEO who I remained friend with. He expressed that it was a good idea and if I wanted to learn the pain of startup for myself, I should do it. Thursday: thinking... lots of thinking--then I came to a conclusion: it must happen NOW! Told my work people and they were very supportive. Friday: I left the company on good terms (the company told me to come back once I have my product developed, they'll be the first customer).

2 things I believe in: 1) you do it because you HAVE TO do it--you cannot live without it. 2) you're always about a few years late :P

With that being said: 1) I am married and my wife and I had some cash to sustain us for a few months so I do have a bit of a nest and health insurance is on the wife 2) My idea is very simple and I believe it can be accomplished within a short time. 3) I cannot live without doing it (living without passion is simply surviving)

If you truly believe in your vision, then you should have no problem laying your life down for your vision. If you are willing to put your life on the line, then like Scar Face "the world is yours"

Good luck, friend and always, fight like hell.

PS: *One condition the wife gave me when I quit was I have to keep a daily work journal. It's very helpful. My recommendation for you is to keep a journal--you will read back on this as perhaps the most enlightening self reflection. You don't have to write all thoughts, just what you did that day and the tasks will tell you what you were thinking.

I agree it makes a lot more sense to start with an iPhone (and Android) app, but being a web developer myself, Fiestastic so far has been an effort of a few weeks, while developing an iPhone app would take a lot more time for me.

First I wanted to see if it was a good idea, and what people liked and didn't like before putting a lot more effort into it (like learning to develop native apps). Also, while native apps really are the best option, it wouldn't be difficult for me to create a mobile version of the site optimized for smartphones, so people can access the service on the go, even if not having the best experience.
>You can make temporary paper glue out of flour and water

Not useful for sealing submerged parts of a shiny metal structure though.

>Either you have enough money to buy some glue, or you can spend time teaching your kids how to make it.

This is how it seems to go. However practically you need grain, so you need a trip to a field with grain in, which would be a bus ride, which would cost more than walking to the shops to buy glue.

Once you're at the field (assuming you have permission), you'll need to gather the grain. Scythe? Sacks? I know from experience that you get little flour from the grain you can hand collect and grind with a couple of flat stones in a couple of hours. Were talking young kids here too, getting them to gather grain won't be much fun when they're moaning "I thought we were making junk boats ... can't we make our boats".

I'm not trying to be completely obstructive (honest!) - making our own epoxy sounds more fun (but again, hidden costs) - but perhaps these things will come later.

That is kind of what I meant by hidden costs.

To recapitulate often one doesn't realise the benefit of the resources one has available. Making a piece of furniture for example someone will say "use your drill press", "use a nail gun", "use an orbital sander", etc.: obviously once one has these things the usage cost is near zero but the acquisition cost is high. These acquisition costs get hidden.

There's a secondary and underlying factor important to consider: vm / language baggage. It's easy to use the cool, hip and shiny new languages, but I don't see it mentioned as an important precursor to disqualifying libraries or frameworks. I don't even think it can be dismissed as an orthogonal issue as it directly precedes the other.

As a non-experienced jvm developer,I wonder what is appeal to be locked in to a vm that eats RAM for breakfast? I tried the cool and hip frameworks in clojure and java. Just saying.

In the postwar era, we [Americans, though I wasn't born, yet] were hopeful about the future. Our science fiction reflected this, but it was just the tip of the iceberg: the whole culture assumed progress and advancement. Immediately after, though, there was a time of fear and pessimism about the future, bringing the concepts of nuclear winter, climate change, resource shortages, and the end of the space age. We call this period "the 70s", and our current culture seems to be far more influenced by that than it is by the previous expectation of momentum and progress.

Also, our basic understanding of physics-as-applied-to-the-limits-of-technology hasn't much changed from 1960 to 2010, unlike the period from 1910 to 1960.

> "I am not convinced it is that useful to have explicitly targeted audiences for advertisement. It may be better to understand and interpret an ad campaign, but generally, what works best when doing statistical prediction is not what is the most intuitive."

If you've collected marketing data that tells you your conversion rate among pet owners is 2% when your conversion rate among the general public is 1%, then you know that every ad you show to pet owners is going to have twice the impact on your bottom line.

Ad targeting enables you to collect this kind of data and to exploit it once you have it. If you find the right audience, your advertising dollars can go more than twice as far.
