Comment Re:Scrubbers: A 1970s Tech Still Absent in China (Score 1) 464

I live in Hong Kong so maybe I could chime in. Hong Kong and the rest of the mainland China is running two system, having different jurisdiction and law.
Factories were moving to Guangdong province (mainland China), where is just 100 mile anyway, anyway regardless of the law because of the cheaper labor cost (around 5 to 10 times).

Plus, factories moved from Hong Kong to Guangdong is just accounted for a small percentage, compare to the whole mainland China. Perspective: Hong Kong population: 7 millions. China population: 12 billions.

Maybe mainland China have some similar environmental protection law, but mostly they could get away by bribing the officials.

Same for NFC and mag-strip. Access to audio maybe easier than NFC signal, but it's still "open" to user. Same for SSL...it's all in-band and accessible.
Last time I read a NFC related spec, a asymmetric encryption/PKI is employed.

If phone company run the signal in-band today with the signal signed with PKI, etc etc, it's just as secure as running it out-of-band. It's just we didn't have the technology to do that efficiently a few decades ago.

It's more like a grounded-airplane, or plane-on-a-rail.

mag-lev is mag-lev not only because it use mag to keep things on rail, but it's the propulsion source. Now that "train" thing is going to use turbo fan engine as the propulsion source, not wheel nor mag. So...hey it's really an airplane

Comment Think of those little routers! (Score 1) 376

99% of them will have to throw away.

Setting up tunneling behind those AP/Gateway router without explicit support is not easy. 6in4 tunneling - have to setup the WAN IP correctly, rinse and repeat for every computer behind.
6to4 would instantly work (maybe slow at start..but if ISP setup 192.0.2.42 gateway nearby) but also requires router (those who had WAN IP participation.
Last but not least - native IPv6 routing, also involve those little boxes...

Just hopes more IPv6 capable AP router show up on the market sooner. Then the data

China forced all foreign willing to take a piece of cake in China to form with China's company. Not just train, but all the automobile players in China...

People couldn't figure that out that China is "learning" the technology along the way? Very much similar to Japan back in 50's I guess?

Here in Beijing has a lot of trolley bus too. But they have to slow down to 10mph when crossing cable intersection or a switch, and most of them are in the road intersection...which blocks all the traffic behind.

Plus, you can't have too many bus running on the street, because apparently they can't overtake each other! Imagine in busy road section where there are 4 lanes filled with vehicles and 1.5 lanes of traffic are buses.

And I also wonder if it will interfere with double decker operation.

Lastly, I don't think the buses are doing regenerative brake yet. Maybe it's just not cost effective?
