...and the entertaining tangent story involving Van Eck Phreaking and vintage furniture.

"Entertaining" isn't a word I'd use to describe that overlong digression in an otherwise entertaining novel. I love Stephenson, but he sure could use a stern editor at times.

It certainly wasn't the only digression either. I think you sign up for this when you pick up a Stephenson book. It's part of his intellectual style.

Hopefully not to stern to leave out Capt'n Crunch and frozen milk.

How much of this just comes down to taste? I enjoyed that whole book, including the digression.

I certainly would. Some of my favorite passages ever, fascinating stuff.

Markus Kuhn’s work on “optical eavesdropping” — reconstructing a CRT image from reflected visible light — is really interesting: https://www.cl.cam.ac.uk/~mgk25/ieee02-optical.pdf

This SDR implementation looked really interesting for sniffing monitor output - https://github.com/martinmarinov/TempestSDR

Alas I don't have a suitable SDR to try it with.

Holy crap, it works for distances up to 120m using a custom built antenna. https://youtu.be/8HV70b-DpE0?t=23m46s

Though $50 will get you enough of an antenna, amp and SDR to get started...

If you want to play around with Van Eck Phreaking, try https://packages.debian.org/sid/tempest-for-eliza , which lets you listen to MIDI-like music via AM radio from your computer monitor.

Unrelated, but at the bottom of http://celeriac.net/sx/public/ is a sonification of Van Eck's sequence
