I can't figure out what that one is supposed to mean!

In short, we’ll trade you iCloud for something great.

I took a class that explained light field photography, but I thought understanding the concepts through static diagrams was difficult. I made a little Mac app that simulates a 2D scene of light sources, lenses, and light-field sensors. The sensors shows their captured output in a graph.
The source is at https://github.com/bridger/optic-workbench
A bit of explanation (and a link to the pre-built binary) is at http://www.bridgermaxwell.com/index.php/blog/optic-workbench....
(Sorry it is only for Macs. I would love to redo it in Javascript someday, once I know Javascript.)

When I was doing this exercise with a friend on Understudy, he found solutions to multiplication and exponentiation too. I'm still trying to wrap my head around the exponentiation. Passing a number to another number?!
(define (multiply number1 number2)
(lambda (f)
(number1 (lambda (x) ((number2 f) x)))))
(define (exponentiate base exponent)
(exponent base))Comment · 12 years ago
I've been making a homemade version of Soylent (http://www.cookingfor20.com/2013/06/18/hacker-school-soylent...) since September. It makes up one or two of my meals each day. I've got to say, I really really like it. I think it has a good chance of catching on. I still love eating out socially, but it has replaced all my my mediocre meals. I can imagine it replacing those aisles and aisles of junk, easy food (cereal, canned soup, mediocre pasta).
That said, I quickly had to come up with a better name than Soylent. I call mine Science (for human consumption). It makes it distinct from food. "Did you get lunch?" "No, I just had Science today."

I am doing the chapter on register machines now. I love the diagrams that show the controller and the data path of the machine. See http://sarabander.github.io/sicp/html/5_002e1.xhtml#g_t5_002...
Scratch and Quartz composer show code in a graphical way. Are there examples of languages that show the data path in a similarly graphical way?
I would love to see how variables relate to each other and other functions (the data path) separated from the order in which these operations actually happen (the controller). It would be an interesting way to debug. For example, variables that get assignment but are never read would be glaringly obvious.

I can certainly see those as the next texts that we add!

I tried to tutor my niece in math using Google Hangouts and various whiteboard apps, but drawing with the mouse / trackpad was pretty difficult. Now we use Understudy and it works great, if I do say so myself.

I am the other guy working on Understudy. The iPad has been the best platform for Understudy so far, but I still have my fingers crossed that Apple builds a better touch screen into their next iPad. Who should I pray to for that wish?

Philipp Schmidt is a big proponent of peer-to-peer learning, and he calls it a pyramid scheme himself. :P http://dmlcentral.net/blog/philipp-schmidt/great-peer-learni...

I am working on a startup, Understudy, that tries to address this problem. Our approach is one-on-one conversations. We find you someone to meet with each week as you go through a book. The first one we are doing is SICP. You meet up with video chat and a whiteboard on the iPad. https://www.youtube.com/watch?v=KrdjKvka558
It should be on the App Store soon (awaiting Apple's approval!). If you are interested in trying it, send me an email. [email protected]

"...numbers that are at or near the highest levels of political and religious disaffiliation recorded for any generation in the last quarter-century." Seriously. How many generations are in a 25-year span?
