ccarpenterg··on Built for Bitcoin. Next Run: Early 2014
The definition of ATM From Wikipedia:

is an electronic telecommunications device that enables the clients of a financial institution to perform financial transactions without the need for a cashier, human clerk or bank teller.

ccarpenterg··on There's a .00006% Chance of Building a Billion Dollar Company
I agree and I think a bayesian approach is more suitable. For instance, the probability of getting into YC:

P(getting into YC | sold a startup, graduated from Stanford/MIT, worked on/built something awesome, etc)

Or the chance of building a $1B company:

P($1B company | you're in SV, $100MM in funding, etc)

ccarpenterg··on There's a .00006% Chance of Building a Billion Dollar Company
I think a bayesian approach is more suitable:

P($1B company | you're in SV, $100MM in funding, etc)

Think about a bayesian network and its joint probability.

ccarpenterg··on Money on the Mind [video]
Something could be perceived as unethical by a poor person but as ethical by a rich one.
ccarpenterg··on Money on the Mind [video]
Well when it comes to business you can replace words like unfair and unethical with a term like 'competitive advantage'.
ccarpenterg··on Show HN: Get Paid on Time - Simplified Payments for Freelance Developers
Is the fiduciary model a common thing for freelancers? I'm not sure of that.

I was wondering how hard is for a non US contractors/freelancers to open a US bank account and then use something like stripe to collect payments. Or maybe collect the money through the bank. That's a real need: a way to easily get paid without using Western Union or the like.

Got it! Thanks.

How do you consider that spam? I posted it on my Google+ account, that was the purpose of the HN circle.

Suddenly I come from another planet. I don't get it. I don't consider my twitter timeline to be spam, for example.

I receive a lot emails from HN related stuff. I think that's fair. If I think it isn't useful for me I just delete it, I don't flag anybody we are here to share things.

Your comment is totally unfair. I've never sent you an email. I didn't spam anybody.

As a best practice you could use a package.json file [1], IMHO.

ccarpenterg··on Meet the Obama campaign's $250 million fundraising platform
In the first UI the users are overwhelmed with all the information they have to fill out in order to make the donation. In the final UI the process has 4 steps.

ccarpenterg··on We're doing for payments what MP3s did for CDs
Recently I've been playing with Stripe to put a payment form (url) into a QR code. So the cashier prints the receipt, the user scans the QR code and pays using the form on her iPhone/Android.

But why would merchants or users prefer this solution? why not just use the credit card? Perhaps these kinds of ideas are what pg calls made-up startup ideas.

ccarpenterg··on How to Stay Relevant as a Web Developer
It looks like the article was written in 2008. PHP or ASP/C#, SOAP? seriously? I think we're in the low part of the quality curve for Hacker News.

ccarpenterg··on How the Rich Got Rich
Interest rates are the price of capital

I think that's inaccurate. The price of the capital is its cost of opportunity. Interest rates are the price of debt.
