I don't think so. The book has 3 parts, but it's not part of a series
It's my hope that future Macbooks and Macbook Pros will all go with USB-C charging. Meaning there can be a middle ground between unsafe bargain basement chargers, and fray-prone Apple chargers.
Wow, I would have guessed the exact opposite. What's the reason(s) for the higher difficulty on the ground? Planning permission? Cost of the land? Needing multiple sites in multiple countries for non-geosynchronous orbits?

That sounds fascinating. Could you elaborate? What's the power level and the application?

It mostly works, but I've found I still don't use it as often as would the real keys.
That sounds like a nice trick. Could you elaborate, or is there any public information you could link to?
I'm trying various not-regex syntaxes. My motivation is: we all agree regex is bad, but we keep using it because it's available everywhere and hence the least common denominator (a schelling point). What would it take to get beyond regex as the goto pattern matching/parsing? At least for casual use.
Browser support is currently limited to Chrome, and possible Windows Edge*
For now it only works with USB. Bluetooth and NFC specs are out, browser support is the bottleneck
The protocol is public/private key based, with the private key strongly encouraged to be in tamper resistant/evident storage.
The protocol is authentication method agnostic. It doesn't care if you use a USB key, a retinal scan, a pin or divination.
You could write a software only authenticator if you wanted, but servers could detect that (and reject it if they chose to) through the attestation certificate you provided. You can't pretend to be a brand X authenticator, because only company X will have the private key(s) matching the attestation certs to sign (batches) of model X authenticator.
Yubikeys are just one implementation of a U2F authenticator. In theory GitHub now works with any present/future authenticators that talks U2F (modulo browser support) e.g. an iPhone+TouchID+NokNok SDK, a Pebble watch+app, an Android Phone+$your_app, an NFC implant, m-of-n wearables
* Microsoft announced something U2F related for Windows 10, I never got to the bottom of what exactly

""" Tokamak Energy is particularly focused on Spherical Tokamaks, pioneered at Culham, because these compact devices can achieve a much higher plasma pressure for a given magnetic field than conventional tokamaks, i.e. they are more efficient.
Theoretical calculations show that a Spherical Tokamak using high fields produced by HTS magnets could be significantly smaller than other fusion machines currently proposed. For example, a compact ST power plant would have a volume up to 100 times smaller than ITER """ -- http://www.tokamakenergy.co.uk/about-us/
