471 million potatos is a lot of potatos.
471 million .2mm bits of plastic is enough to cover in plastic all of the living rooms in California.
Wait - no - one living room. Or about a dinner-plates worth a day.

Every day. That's the difference.

Even assuming that it's a dinner plate sized amount of pollution, over two decades, you are looking at 7300 dinner plates. Only, broken into little chunks, easily consumed by aquatic life and smothering plants, clogging pipes etc.

What rubbish. Plenty of cultures have parents who are involved in their children's education. My own parents were extremely involved, and as the only child, they put a lot of time and effort into my education and extracurricular activities. To this day, they are quite interested in my career, and are just as involved in teaching my own year old language and music.

That is not a statement on their children's capabilities. Tiger moms are common, and it just demonstrates responsible parents who are genuinely interested in their kids' well being.

My wife and I will certainly be taking an interest in our kids' education and lives, and that is not being overprotective -- that is good parenting.

Some of the greatest minds have been interested in seemingly trivial and popular problems (e.g., Richard Feynman).

This is about science and engineering, and whether or not a phenomena can occur, and it's about public's reaction to something that was proven scientifically.

He doesn't seem overweight for me.

While I feel for the family, to say that he is not overweight shows just how much society's perception of being overweight has changed.

Take a look at this picture, for instance.

And take a look at the body fat visual chart for comparison.

With the overhanging belly, he is easily 35-40% at least. While the majority of people today are fat (especially in the US), that is not healthy. If anything, until recently, 20-25% used to be average.

Above 25-30% is the fat territory, and that's when you start increasing your risk for heart attacks, diabetes, and strokes. Mr. Goldberg may have had a lot of things going for him, but he is most certainly more than a little overweight.

Assuming he's ~6 feet, I would argue that he is probably ~30-40+ lbs overweight. That is not at all healthy. I'm not arguing everyone should have abs, but there's a happy medium here. Mr. Goldberg is very clearly on the unfortunate side of the medium.

Multiple IPs was one solution, but the other was much simpler.

The real address of the computer was its MAC, the prefix simply said how to get there. In the event of a failover, the client's computer would be notified the old prefix was now transitory and a new prefix was to be used for new connections.

At the last common router, the router would simply swap the transitory prefix for the new prefix. The packet would then go by the new path.

The server would multi-home for all prefixes it was assigned.

At both ends, the stack would handle all the detail, the applications never needed to know a thing. That's why nobody cared much about remembering IP addresses, because those weren't important except to the stack. You remembered the name and the address took care of itself.

One of the benefits was that this worked when switching ISPs. If you changed your provider, you could do so with no loss of connections and no loss of packets.

But the same was true of clients, as well. You could start a telnet session at home, move to a cyber cafe and finish up in a pub, all without breaking the connection, even if all three locations had different ISPs.

This would be great for students or staff at a university. And for the university. You don't need the network to be flat, you can remain on your Internet video session as your laptop leaps from access point to access point.

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.

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.

You can get a buff body with a reasonable workout regimen in less than a year, and many elements of your "looks" can easily be fixed (better hair, wearing contacts, getting teeth fixed, dressing more stylishly).

If you have game, then your dick size doesn't matter, because history is rife with examples of men with questionable looks and stunning women.

Ultimately, having good social skills is much more important than any of those things in getting laid.

Basic is a high level languish. APL is a high level anguish.
