Comment Here's the bike problem (Score 2) 151

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.

Submission + - Philae Found! Rosetta Spies Dead Comet Lander (

astroengine writes: With only a month before its mission ends, the European Space Agency's Rosetta mission swooped low over Comet 67P/Churyumov–Gerasimenko to see the stranded Philae lander jammed in a crack. After months of searching for the lander, which made its dramatic touchdown on Nov. 14, 2014, mission scientists had a good idea as to the region the robot was in, but this is the first photographic proof of the lander, on its side, stuck in the craggy location called Abydos. "This wonderful news means that we now have the missing 'ground-truth' information needed to put Philae's three days of science into proper context, now that we know where that ground actually is!" said Rosetta project scientist Matt Taylor in a statement.

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).

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.

Comment Re:Killing jobs? (Score 2) 381

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.
