457: Rubber Duck Phase Cancellation

Chris and Elecia chat about their ongoing efforts to create and learn. Then they answer some listener questions.

Duck quacks do echo but the echoes seem to align in phase so that there is no interruption making the echo sounds like an extension of the quack (Mythbusters episode in which Jamie says "Quack, damn you!")

Elecia continues to work on Making Embedded Systems, 2nd Edition. The early release copy is available on the O'Reilly Learning System.

Classpert is offering an asynchronous cohort for Elecia's Making Embedded Systems course. You'd be going through the class with others and there will be discussions and mentor (and Elecia's) help on the Discord. No live classes but you get access to the best bits of the previous live classes. Class starts in September.

Tickets are on sale for the tenth annual Hackaday Supercon is Nov 3-5, 2023 in Pasadena, CA. Someone there will be giving out stickers. More details to follow on that front.

Elecia is enjoying OrigamibyBoice Crease Pattern Class YouTube series. (It is a prereq for The Plant Psychologist's Origami Design Class.)

Last week's newsletter (sign up here!) had tidbits about learning the Kalman filter. Some of that came from Elecia's blog post about it, some were fresh.

There doesn't seem to be a good introduction to semantic webs in linguistics. Here is a too-dense article about Semantic Maps as Metrics on Meaning from a Linguistics Discovery Journal.
