So many readers know neither of those abbrevs that I think we should just take a prefix of the title (since it's too long to make HN's 80 char limit). I've done so now.
The 2nd edition has 200+ increased in pages count compared to the 1st edition. Chapter's structure is about the same but there's one new additional chapter on transmitter design. In addition to that there's an extension to review of linear algebra (now two parts instead of one). I have not yet received my 2nd edition but from the ToC it seems that the new book will be an excellent textbook to learn DSP for communication systems.
I will second the Dygma Raise. It's a great split keyboard with a staggered layout and eight thumb modifiers (rather than a single spacebar). This was great for me since I didn't want to take on the learning curve of a ortholinear layout.
It's a staggered, 60% split keyboard, with the spacebar replaced with an 8-key thumb cluster. The familiar layout minimized my learning curve and their custom layout software is decent.
A way to counteract this would be to interconnect the mics to determine the origin of the sound and its flow. Nefarious drivers honking while passing the green light could be ignored, or have the green light cut short (but then you risk penalizing drivers behind them who might not be responsible).
