It looks like it currently doesn’t ship to Japan. Any plans to include Japan in the future? I would have pre-ordered already if it did.

Maybe they haven't finished localizing the content for those countries yet?

Maybe, but some of those countries are quite big markets. Why would Apple miss out on those?

It's always rights.

The composers may be largely long-dead, but the recordings are controlled by labels, so there are rights involved.

I tried "Penrose tiles"

Sorry, could I ask which talk you are referring to?

I think the movie you are referring to is District 9.

You might also want to look at Pony. https://www.ponylang.org

Thanks for the link! One nice thing about the original post is that it runs inside of a Swift playground, which, for those with Xcode (or an iPad) can be a fast way of learning and experimenting. I could see someone starting with this project and then easily expanding their knowledge by modifying it using resources like the one you linked to.

"practical program development" implies that it is intended to make things and is not just proof of concept, no?

I read it as they're talking about making proof assistants practical one day, and CakeML is a step on the road to that goal. If they then move onto the next step, where does that leave CakeML?

I know that my Japanese friend has been using CotEditor for a long time exactly because of its Japanese text handling.

Really cool. Those who are interested in a similar project should also check out Super Debugger.

https://github.com/Shopify/superdb

It uses F-Script but, as I understand it, uses its own debugging environment rather than tying into lldb.

Just to clarify F-Script is suitable only for debugging Mac apps. Super Debugger looks really cool for iOS.

Also, F-Script doesn't leverage lldb. The use of lldb in the example here was just that you can use lldb to attach to and load a library (bundle) into an arbitrary app process.
