length implies an ordered sequence.

Coincidentally I received a used SQLite textbook from Amazon today with this database design tucked inside. https://pbs.twimg.com/media/BsigXtOCcAAIGJh.jpg

Discovering design notes in old textbooks is one of the joys of buying used books.

Pluggable Type Systems: http://docs.oracle.com/javase/tutorial/java/annotations/type...

They removed in-app purchases. For me at least, the added friction will make me unlikely to discover or purchase new titles and I may not even keep up with the existing series I read.

Thanks for that - I posted this in the hope that someone could provide some background.

Unfortunately http://trac.sacrideo.us/wg/wiki/R7RSSmallErrata is currently returning 503.

Between all the meetings and other nonesense in a large corporation an actual engineer is lucky to be coding 30% of the time.

Working memory (the active feedback loops that constitute your current thinking) is subtly different from short-term memory. This is still an area of active research.

Working memory can hold a limited number of things (usually said to be 7), whereas short-term memory has a larger limit in capacity and time. These are both temporary systems that feed off each other and rely on the larger long-term memory to give meaning and context to the "symbols" they contain.

Everything is interconnected, so making definitive statements about any of this is hard.

Have you considered using Ethics rather than Morality ?

I hear the word morality and immediately assume the speaker/writer is arguing from a religious point of view.

But how much of that is bundled assets vs actual code bloat ?

Version 7 now installs as an app on OS X.

Which 99% of iOS users won't do even if they are aware of it.

Thanks - yes I was aware.

I thought that Whalesong was a Javascript code generator rather than a VM ?

Unfortunately JS performance on iOS rules that out for our purposes.

The target platforms are iPad, Android Tablets and Web - so Racket cannot be the runtime platform without a lot of tangential work.

I'm hoping that the prototyping can lead to Racket being the tools and authoring platform.

Racket is a great environment for developing DSLs and graphical tools.

Using it full time for my day job (prototyping game engines and DSLs).

It wasn't a normal "ding!" text message - it was sirens and all-hell-breaking-loose.

I was asleep when it went off and my immediate thought was that my phone had some sort of LiOn-battery-about-to-explode warning system. It freaked me out.

I think the whole point of his series of talks is to inspire others to invent new things that not even he has thought of.

I hope that in another 40 years the fact that programming and programmers ever existed is seen as temporary blip in the evolution of computing.

I'm lucky enough to work at a place that is building Math games for K-6.

I watched the curriculum experts and content design teams white-boarding the many ways to conceptualize and visualize fractions for several weeks. It's not the simple domain you might think.

How can the end-user then replace the executable on their iOS device ? That is the problem.

Is anyone here planning an implementation ?

Didn't they try this before ? http://www.govtrack.us/congress/bills/112/s1614

What is their monetization strategy ?

This recent HN comment about Julian Jaynes's The Origin of Consciousness in the Breakdown of the Bicameral Mind is worth following up on:

https://news.ycombinator.com/item?id=5866404

As I understand it the theory posits that consciousness is only a very recent development in humans.

How can we ascribe consciousness to any other form of life when we do not even understand what it means for ourselves ?

There are many examples of programming language runtime apps, such as

Scheme: https://itunes.apple.com/us/app/gambit-repl/id434534076

OCaml: https://itunes.apple.com/us/app/ocamlexample/id396515573

Python: https://itunes.apple.com/us/app/python-3.3-for-ios/id5779112...

Codea (LUA): https://itunes.apple.com/us/app/codea/id439571171

What restricts these apps from being awesome is that they cannot download source code or accept source code pushed to them from other apps. Cut-n-paste is the only way to transfer existing code.

Any alien species that is capable of coming here, and curious enough to want to learn about our form of life, is probably more than capable of doing so without alerting us to their presence.
