How advanced do you go? Can you tailor the course for people who have limited experience programming in iOS and want to learn more?

My quora question relates to this, please answer if you can:

I have recently been reading blake masters notes on the class and I find them extremely valuable. They are written so well I feel like I am reading a transcript of the real lecture. It feels like I am getting the source material even though they are a students notes.

I bet the book will be even better since it is revised by Peter himself. I can't wait to read it as well.

It would be cool if you also had someone explain a little about the internals of the product. I really enjoy watching these khan academy videos. Check them out for an idea of what I am talking about:

I love this website. I like the variety of products.

Really sweet.

It makes sense that robots should learn similar to how humans learn, by analyzing data from many trials and then adjusting the method used to achieve the goal. Instead of manually trying to think of the algorithm. It seems like all AI should be done this way, by learning.

I signed up for the beta, I would love to help

and maybe even for aid relief to charities in emergency situations

This is really amazing. I hope your service receives a lot of success.

One problem is that many people don't have bitcoin even if it is the best way to pay. Many people are uncomfortable buying bitcoins.

Amazon micropayment service lets you pay with credit card transaction anywhere from $0.05 to $9.99 with a 5% + .05 cent transaction fee. Which isn't as good as bitcoin but it is still pretty good as far as credit card fees go.

Many small micro-payments can really add up. This can be huge for content creators. I would really like to give tips to people who create educational science videos, open source software, open source hardware, write detailed tutorials for hardware and software projects, take the time to help me on forums, etc. Many content creators on the internet have helped me. I might not want to give a lot to each but I can give a small tip. Which can still make a difference to the creator if many people also do the same.

I think if they charged a fee for the tip it would be a more standard business model and people would not find it as exciting. It seems more direct to customer this way without the man in the middle dilemma for content creators. Also charging a fee in addition to the transaction fee would make it increasingly difficult to tip the creator a small amount. I think the fact they don't charge a fee on top of the transaction fee is out of necessity.

Algorithmic Information Theory is really amazing to me. I am still learning about it but I feel like I can see the connection to nature.

I have been waiting for UrtheCast (http://www.urthecast.com/) to start live streaming the camera they had the Russians mount on the ISS awhile back.

Is this the same camera?

The show that this clip is from is amazing! The Moon Machines. I highly recommend it

This isn't exactly what I was thinking. When you sign up on Goodst.org you sign up to a plan that charges your credit card about $6.00 a month. Even though they let you choose where to direct .25 cents each day. So overall you have to be willing to give at least $6.00 a month.

I was hoping to really lower the barrier to donating by only asking for a .10 - .20 cent donation per person, per month. I think many more people would be willing to donate .10 - .20 cents per month instead of $6.00 per month.

.10 - .20 cents a month would not be a noticeable difference to most people, so people would sign up without any concern about their own finances. As long as they could trust the payment options and donation service.

Lets take a look at a possible scenario here. Currently amazon micropayments charges credit cards 5% of transaction value + $0.05 for transactions anywhere between $.05 - $9.99.

Lets consider single transactions between .10 - .20 cents. Any transaction in this range comes with a 6 cent transaction fee. So you would receive a net payment of .04 - .14 cents per person per month.

Imagine an example where each person donates .20 cents and we receive .14 cents net per person after transaction fee. How many user do we need to get $500,000? About 3.57 million users.

Seems like a lot of people but it is only about .01% of the United States population. And since the website could take donations from anyone in the world willing to give .20 cents a month, I think attaining practical large sums would be achievable. And extremely affordable!

So .25 cents a day is good if you can afford it, but .20 cents a month is soo extremely affordable for most people and with scale it could add up to a lot!

Depending on the content, I would consider even charging less, anywhere down to couple cents, given a practical micro-payment system.

A crowd-funding charity website that collects monthly very tiny micro-payment (as little as .10 cents) from users for charity. This way many users would sign up, worry free, as .10 cents a month is extremely affordable and can add up to a lot of money with scale.

I think 'Ask HN: Idea Sunday' is a great idea, I am definitely looking for a project to work on and this is very helpful. Look forward to seeing this continue.

The site has an amazing collection of UI experiments and tutorials! Love it!

They did a good job with the website.

Your analogy only address's the issue form the consumers point of view. What about if you make a product, should you be able to force a distributor to carry your product?

Shouldn't we think of the App Store in the same way that people and companies cannot force a retailer to stock their own product.
