Lol'd . To the contrary, it _can_ happen, and when it does the behaviour is undefined for C/C++. However, rest assured - you are probably on a x86_64 machine programming in sth like Ruby or Java script, so your Apps should be alright :P
As someone who works in the application layer, the recommendation to have a fast failover to tcp from udp seems silly. Shouldn't the recommendation be to keep packet sizes below 1280?
The reality that to much stuff in networks (mostly firewalls, NAT and other middleboxes like that) only understands the basics (TCP, UDP, random bits of ICMP) and drops SCTP. You can do SCTP over UDP, or use it in networks you can control and fix, but not reliably as-is over random internet connections. So we now have HTTP2 and other protocols now reinvent parallel streams instead of swapping to SCTP, but that's how it is.
SCTP is alive and vell in very niche applications. SIGTRAN [1] for example is an adaptation of middle layers of SS7 network stack that runs on top of SCTP/IP.

it does, in some ways. I imagine if you're using UDP you have a specific application in mind that may not be performant over TCP... otherwise why not just use TCP by default?
But then you need to design a system to make sure all the packets arrive, including sending missing packets, and that they're processed in the correct order. Or you could use a time-tested off the shelf system to handle this complication: TCP.
He's one of the few people in the world with a more nuanced understanding of blockchains than either "it will male bankers obsolete" or "it's useless nerd money", and that writes about it publicly.
If he was satoshi he would just sign a message with the genesis block's private key saying so. He wouldn't announce that he's going to move an early coin on the bbc. It's simultaneously the most convincing proof and the easiest proof to do.
I agree. It's very hard for me to believe that he can both have been so clearly well-versed in crypto and with its beauty, enough to create a masterpiece like bitcoin, and at the same time hesitate to just sign a message. Not only is signing something convincing and easy, it's taking advantage of that same beauty of crypto that he should appreciate so much.
It seems backwards to me that someone like Satoshi who obviously does value privacy and anonymity would get on BBC and declare "I am Satoshi, and I want to be left alone" and yet at the same time not take the cleanest, least extravagant option of just signing something.
