Windows has had IPv6 stacks since Windows 95 and Microsoft even started supplying them as of 98.

IPSec is perfectly usable.
Telebit demonstrated transparent routing (ie: total invisibility of internal networks without loss of connectivity) in 1996.
IPv6 has a vastly simpler header, which means a vastly simpler stack. This means fewer defects, greater robustness and easier testing. It also means a much smaller stack, lower latency and fewer corner cases.
IPv6 is secure by design. IPv4 isn't secure and there is nothing you can design to make it so.
IPv6 would help both enormously. Lower latency on routing means faster responses.
IP Mobility means users can move between ISPs without posts breaking, losing responses to queries, losing hangout or other chat service connections, or having to continually re-authenticate.
Autoconfiguration means both can add servers just by switching the new machines on.
Because IPv4 has no native security, it's vulnerable to a much wider range of attacks and there's nothing the vendors can do about them.
Each level is given the parent's prefix plus one or two bytes. Yes, you can announce that and it is easily summarized.
Anycast tells you what services are on what IP. There are other service discovery protocols, but anycast was designed specifically for IPv6 bootstrapping. It's very simple. Multicast out a request for who runs a service, the machine with the service unicasts back that it does.
Dynamic DNS lets you tell the DNS server who lives at what IP.
IPv6 used to have other features - being able to move from one network to another without dropping a connection (and sometimes without dropping a packet), for example. Extended headers were actually used to add features to the protocol on-the-fly. Packet fragmentation was eliminated by having per-connection MTUs. All routing was hierarchical, requiring routers to examine at most three bytes. Encryption was mandated, ad-hoc unless otherwise specified. Between the ISPs, the NAT-is-all-you-need lobbyists and the NSA, most of the neat stuff got ripped out.
IPv6 still does far, far more than just add addresses and simplify routing (reducing latency and reducing the memory requirements of routers), but it has been watered down repeatedly by people with an active interest in everyone else being able to do less than them.
I say roll back the protocol definition to where the neat stuff existed and let the security agencies stew.
These are well-established, well-tested, well-designed protocols with no suspect commercial interests involved. QUIC solves nothing that hasn't already been solved.
If pseudo-open proprietary standards are de-rigour, then adopt the Scheduled Transfer Protocol and Delay Tolerant Protocol. Hell, bring back TUBA, SKIP and any other obscure protocol nobody is likely to use. It's not like anyone cares any more.
...but if that acronym has also been used by Beiber lately I am SOL.
What does the Skilled Occupation List have to do with this?

He claimed he could hack the plane. This was bad and the FBI had every right to determine his motives, his actual capabilities and his actions.
The FBI fraudulently claimed they had evidence a crime had already taken place. We know it's fraudulent because if they did have evidence, the guy would be being questioned whilst swinging upside down over a snake pit. Hey, the CIA and Chicago have Black Sites, the FBI is unlikely to want to miss out. Anyways, they took his laptop, not him, which means they lied and attempted to pervert the course of justice. That's bad, unprofessional and far, far more dangerous. The researcher could have killed himself and everyone else on his plane. The FBI, by using corrupt practices, endanger every aircraft.
Did the FBI have the evidence that he had actually hacked a previous leg of the flight, or did they not?
If they did not, if they knowingly programmed a suspect with false information, they are guilty of attempted witness tampering through false memory syndrome. Lots of work on this, you can program anyone to believe they've done anything even if the evidence is right in front of them that nothing was done at all. Strong minds make no difference, in fact they're apparently easier to break.
Falsifying the record is self-evidently failure of restraint.
I have little sympathy for the researcher, this kind of response has been commonplace since 2001, slow-learners have no business doing science or engineering. They weren't exactly infrequent before then.
Nor have I any sympathy for the airlines. It isn't hard to build a secure network where the security augments function rather than simply taking up overhead. The same is true of insecure car networks. The manufacturers of computerized vehicles should be given a sensible deadline (say, next week Tuesday) to have fully tested and certified patches installed on all vulnerable vehicles.
Failure should result in fines of ((10 x vehicle worth) + (average number of occupants x average fine for unlawful death)) x number of vehicles in service. At 15% annual rate of interest for every year the manufacturer delays.
That's cheating.
And inside, a modern x86 processor is actually a giant hardware emulation of x86 instructions with a RISC/VLIW core... You call it cheating, and I call it optimizing.
They second you try a cool trick like migrating a thread to another machine...
But this would happen with a macrokernel as well... you can't just magically make networking overhead disappear...
I wasn't intending on saying that CISC was superior to RISC... what I was more saying is that there has been more money put into CISC processors, and so they develop faster.
It's just a simple fact of money == better access to stuff to make more money.
The main reason CISC is faster today is probably more related capital investment needed in production. Intel just have so much more.
This was basically what I was trying to say. More capital investment typically means better outcomes.
Someone in the Youtube comments says "The flight profile veers the booster off to the side on purpose so the exhaust from the final burn isn't directed at the barge where it could do damage"
If this was a planned manoeuvre, I'm much happier. Can anyone confirm this statement?
I was shocked at how abrupt and extreme the pitch changes were. I think so long as it needs such gross adjustments so close to landing, landings will be unreliable with a significant chance of failure. It is not at all like the tidy landings made by the Grasshopper test vehicle.
Two engineering changes which could make a big difference are lower minimum thrust (so it can approach the landing with lower acceleration) or lateral control rockets (RCS) at the top of the stage.
