The baud rate is insignificant of throughput, it's not clear why it was even mentioned, especially in relation to throughput. Each note encodes 4 bits (a hex digit), so although it does run at 1 baud, the system runs at 4 bps.
Your math is way off. With 8 notes, each encodes 3 bits; two notes allow 64 different combinations (not 1.6 million!), or 6 bits.
No, the only point of evolution is successful reproduction. It makes no difference how long you survive. If your genes aren't passed to offspring, any evolutionary change you may have had dies with you. Likewise, it makes no difference if you die after producing self-sustaining offspring - your contribution to the gene pool carries on.
Relying on the difference in current draw for a specific current phone is naive, at best. For the reason that assuming the delta in power draw from turning off the LTE radio isn't an accurate reflection of the actual power usage for LTE, you need to understand how Verizon's active dual-mode accesses the network, and the power costs involved in tracking, and switching between separate CDMA and LTE connections.
You need to read up on SC-FDMA, CDMA2000, PAPR and frequency diversity gain with regard to uplink power efficiency. Knowing something about DRX would help you understand idle mode efficiency, too.
You seem to be confusing implementation with technology. We're in the early stages of LTE chipset evolution, and the end stages for CDMA, so it's expected that current CDMA chipsets have better implementations. That doesn't support the claim that "LTE kills battery life." Maybe it does on your phone, but my VZW 4G phone can sit idle for well over 24 hours with 4G turned on (I have never seen a need to turn it off), which seems very competitive with other Android phones.
No, it doesn't. LTE is actually claimed to be more efficient than CDMA. Where LTE consumes more power than CDMA, it's delivering much greater bandwidth.
The problem is, current networks continue to use CDMA for voice, adding LTE only for data. That's what kills battery life - having to run multiple radios. A current 4G phone has to do everything a 3G phone does, and more. I'd expect that once a carrier has completely built out their LTE network and gotten it tweaked, they'll roll out voice on the LTE side. At that point the need to have a CDMA radio in the phone will go away, and battery life (all else being equal) should be better that it was with 3G.
Nope. The claim was that this incident would have been prevented if the phone had a replaceable battery. That's nonsense - the cause was a shoddy repair.
If you want to play "what if," then in some other case, if someone has a phone with a replaceable battery, there's also a much greater chance that they would carry a spare, and have that get shorted out or punctured. Or have a screw left loose inside after a repair, ready to cause a short, with similar results.
If they want to have the advantages of a common carrier - free access to rights of way, and a monopoly on services, then they better behave like a content neutral common carrier. If they want to take the attitude that it's their network and they can control it any way they want, then they can also negotiate rights-of-way individually with the millions of property owners whose land their cables cross.
Bad summary - there are two links, both with text which describes problems with the current system, and neither of which would seem to point to this "Easier Fix" mentioned in the headline. Why not link some text which at least makes minimal sense, like "...experts have found an easier way."?

They need to explain it better/more fully. As it reads, you give them those rights independent of any particular service-related need. Per the terms, they could publish your content even it that weren't your intent. If they said something like "If you use the service to share content with others, you give Google the rights necessary to provide that service. You give Google the right to copy your content for reasonable and customary purposes (such as making backups, or moving content between servers)." (IANAL, there's undoubtedly a better way to phrase it, but that's the concept)
You do realize that SecurID-type tokens do nothing to prevent man-in-the-middle attacks? If a phisher can find a phish who doesn't check sitename/ssl info to verify they're really connected to the bank's site, they're in.
...and other than relying on the user to recognize that they have a secure (HTTPS) connection to the legitimate site, with a legitimate cert, what's to stop a man-in-the-middle/proxy attack (unless your token somehow could do end-to-end secure authentication, but if you're reading a PIN and typing it in, it doesn't.
Couldn't such a site could alter transaction data (changing amount, destination account for payments/transfers, etc), and pass that along with proxied credentials? Or simply create new transactions once authenticated? If the site asks for, and gets, the user to enter debit card #, PIN, and token code, doesn't it have everything needed?
"the most prominent being the ban on encrypted transmissions"
There is no such ban. There is a rule that says "data emissions using unspecified digital codes must not be transmitted for the purpose of obscuring the meaning of any communication," but that's a matter of intent. For instance, if one encrypts a remote control signal, not to obscure it's meaning, but for the purpose of protecting it from interference, that's legal. If one takes advantage of a ham license to communicate with a high power 802.11 AP in the ham portion of the 2.4 GHz (13 cm) band, one might legally use encryption to prevent non-ham access to that AP (which would be illegal).

What about... the manager who asks why she can't print to the printer that was recycled years ago (and her specific words were "Why can't I print to the printer we got rid of?" - so she knew it was gone)?
You say that as if she's stupid. She knows what she wants - this is a problem with your understanding of a non-technical user. Good tech support people aren't strict techies, they have to be able to understand things from the user's perspective.
It was probably that her default printer was still set to the old one and she had to change it every time she printed. She wanted to know why she couldn't print to her old printer, which was still there on her PC, like it had always been. Change the default for her. Default for a user means their house is going to be foreclosed.
Less likely, she just wanted to print to the same printer name she was used to - so ask where she expected the paper to come out, and rename that printer on her PC to have the name of her old printer.

The repair was for a broken screen, not a battery replacement. Your claim is a non-sequitur.
