The Saturn V was tested without humans in the Apollo 4 and Apollo 6 flights. The second of these discovered "pogoing" behavior, which had to be fixed before Apollo 8. The astronauts were brave guys - "Final testing of modifications to address the problems of pogo oscillation, ruptured fuel lines, and bad igniter lines took place on December 18, a mere three days before the scheduled launch".
The "San Francisco bicyclists can breathe a sigh of relief" comment surprised me until I saw that Uber has a problem with turning right across bike lanes. This certainly isn't a problem for all self-driving cars. In the South Bay I've seen a self-driving car do exactly the right thing: signal, merge into the lane when it turns from solid to dashed, stop at the red light, and then turn. That's a lot better than the average human at the same intersection; seeing someone signal and merge and stop would be quite unusual.
Skylab fell on my defenceless homeland. On News at Ten (ITN), Reginald Bosanquet, overcome with disbelief, read his autocue one line at a time. ‘Skylab broke up, with debris. Streaking across the night sky and heading. Thousands of miles across the. Ocean for Australia.’
At least Reggie wasn’t entirely speechless. I’m bound to confess that I was, since until that point I had been an admirer of President Carter. But when they start strafing your own country with tons of red-hot supersonic junk you can’t help wondering whether there might not be some substance in all those theories about US imperialism.
Most human-driver-related deaths so far are based on incidents that would be easily handled by a human driver.
Seriously, signaling turns, slowing down when needed, stopping when needed, looking through the windshield instead of down at your smartphone... These are not rocket science, and yet people fail every hour of the day.
1. Sprint, a major ISP, has 2600::/29 - two billionths of the possible IPv6 addresses
2. ????
3. We're doomed! Somehow.
You should show your math for running out in 20 years. That takes a lot of/29s (five hundred million). Also remember that end users can get a/48, which is 524,288 times smaller than a/29, or/56, 256 times smaller again.
There has been quite a lot of progress in residential broadband too. The "Networks" tab of Akamai's IP adoption visualization page shows Comcast at 44%, TWC at 22%, and Sky Broadband at 53.5%, alongside the mobile carriers moving to IPv6.
The smartphone migration is also progress as it has helped to remove the old chicken-and-egg problem for IPv6. Why should websites take the effort to support IPv6 when the eyeballs aren't there? Well now the IPv6 eyeballs are there, and there's a lot of content for them: Google, Facebook, Wikipedia, Akamai, etc.
These scenarios are just a little bit contrived... I can't fathom any real life scenario where any of these situations would occur with the odds of both options being equal, which is the point where the software would be called upon to exhibit a preference of one option over another.
Exactly. Why don't people discuss the millions of small decisions - "how quickly shall I go through this stop sign?", "should I signal this turn or is it too much hassle?". Those are where the existing human software is causing bad consequences on a daily basis.
No, let's discuss the one in a billion corner case instead.
Now: NAT is carried out on a crappy box in your house. You phone up the call center with a problem and they ask you to power cycle it.
Dystopian IPv4 future: NAT is carried out on a huge crappy box somewhere in your ISP's network. You have to persuade the call center person to do something to that mega-box to fix your problem. Of course that doesn't fix your other more permanent problem (that your IPv4 address is shared with five spammers, sixty owned PCs, and one madness-addled insaneonaut who keeps getting blocked on Wikipedia).
Especially at the weekend. Last weekend more than 11% of Google users were using IPv6. It's higher at the weekends because IPv6 is coming much faster to residential broadband and mobile, with corporate networks migrating more slowly.
Runkeeper also keeps trying to sell you a premium service, which has more analytics. There is also the "reward" after you complete some accomplishment, which seems to be some product discount, and they probably could make money from advertising there.
Last year I wondered if it was a Runkeeper developer asking what to do when dividing by zero. If you stay completely still for an entire workout, it decides that you are running at "zero minutes per kilometer" and even congratulates you on setting a new record.
Sometimes the phone's GPS has been still running after I've finished, and I have had to swipe away the app. Up until now I've assumed this was incompetence on their part, rather than malice.
Agreed. I've seen a self-driving car signal, move safely towards the right curb when the bike lane changes from solid to dashed, stop at the red light, and then turn.
Most human drivers in the Bay Area can't even signal, let alone do "advanced" stuff like being in the right place or stopping at a red light. I get a great view of their antics from my perilous place in the bike lane.
Traditionally writers put a space before an opening bracket (like this), but I'm seeing a lot of Slashdot contributors scrunch up the bracket against the last word(like this). Also there are people who don't write the spaces in "a lot" or "at least", and other similar phrases. I wonder if this War on White Space is partly down to Twitter and its character limit.
Also the home routers these Kindles connect to are hardly wonderful examples of how to do security updates either. Maybe one firmware update and you're on your own until the router hits the e-waste bin.
The Bad:
-They did away with IPV4's simplistic subnetting and supernetting
"Simplistic" means "excessively simple", which hardly seems to describe subnetting in IPv4 - should you go for a/27, or a/26, or a/25? IPv6 is simpler, as you don't have to worry about running out of LAN addresses.
Some tourists in the Museum of Natural History are marveling at some dinosaur bones. One of them asks the guard, "Can you tell me how old the dinosaur bones are?"
The guard replies, "They are 3 million, four years, and six months old."
"That's an awfully exact number," says the tourist. "How do you know their age so precisely?"
The guard answers, "Well, the dinosaur bones were three million years old when I started working here, and that was four and a half years ago."

I don't think that's really a choice, but no, I don't want that.
I mainly posted about Skylab because I am amazed by the lack of historical context in a lot of the comments here.

If the equipment/personnel is there to run one cable, then why not run 2, or 3 or more.
Also one cable can have hundreds of fibers. For example, this one has 432 fibers.

I must bookmark the GP post so that I can make a weak joke in August 2020 :)
So the representation of dates must either handle negative values or have some other method of representing dates as far back as 14,000,000,006 years.
Reminds me of this joke:
Some tourists in the Museum of Natural History are marveling at some dinosaur bones. One of them asks the guard, "Can you tell me how old the dinosaur bones are?"
The guard replies, "They are 3 million, four years, and six months old."
"That's an awfully exact number," says the tourist. "How do you know their age so precisely?"
