I noticed from the logo that 2026 is evidently the 75th anniversary of the Lincoln Laboratory.

I second this recommendation. For those interested, this is “An interactive application for maths and graphics based on the Lua programming language and the GNU Scientific Library.” for both Windows and Linux. I installed it and keep a shortcut on my Windows desktop for quick calculations.

I appreciate your offer, but there’s no need. I subsequently found a copy here:

Maybe I’m missing something, but that webpage only seems to provide a PDF containing the beginning of the book (up through the Preface). Perhaps you need a ACM Digital Library Premium subscription to access the entire book?

It’s great that Libbrecht put a copy of his 500+ page ‘Snow Crystals’ book on arXiv [0] before an updated version was published by Princeton University Press [1].

I completely agree that this is a great resource. BTW, the Springer site book link is https://link.springer.com/book/10.1007/978-3-642-14764-7. I’m thankful that the author has made the book and code freely available.

The author also co-authored a book about historical and state-of-the-art pi computations called Pi Unleashed (https://link.springer.com/book/10.1007/978-3-642-56735-3). The code and additional resources are available at https://extras.springer.com/?query=978-3-642-56735-3. Though somewhat dated (circa 2000), there’s a lot of fascinating information in the 229 Mb zip download, including a 133 char C program (pitiny.c) that computes 15000 digits of pi.

I don’t know what the best book would be, but I found this extract from Andy Farnell’s book “Designing Sound” to be a very helpful introduction to Pure Data:

http://aspress.co.uk/ds/pdf/pd_intro.pdf

Another useful book is “Loadbang - ProgrammingElectronic Music in Pd” by Johannes Kreidler. The 2nd edition is evidently out of print, but a free download is available here:

I found the Guided Tour very helpful for getting started with Factor:

https://docs.factorcode.org/content/article-tour.html

It's also available for browsing in the Factor browser with code that can be clicked to execute directly in the Factor listener, making it easy to follow along.

As far as I can tell, this technique relies on post-processing of data from the separated detectors, so it isn’t a realtime system.
