*Update on the Mu computer*

Mu now has support for Unicode. Just graphemes that map to single code points; no combining characters.

Mu also is starting to gain a fake screen that (interactive) programs can print to in tests.

Here's how it looks: https://archive.org/details/akkartik-2min-2020-09-02

Strings are arrays of bytes. To iterate over the graphemes in a string, store it in a stream and read graphemes from the stream.

*Update on the Mu computer's memory-safe language*

Mu now type-checks calls to functions implemented in unsafe SubX machine code. I have to provide signatures explicitly, and they look like this:

RT @BMorearty@twitter.com

Recently I tried @excalidraw@twitter.com & was stunned to see it open/save a file almost like a normal app. No upload/download.

In the commits I saw @tomayac@twitter.com had added this capability using Native Filesystem API.

In this #webdevlive talk he shows how to use the API. https://youtu.be/r3QPKK0JPtI?t=5958

I'm a regular used of `hexdump` to view an hexadecimal dump of a file.
But I wasn't aware of the `hexcurse` hexadecimal *editor*.
