My joke was: If you insist on promoting an old system (overhead cables) why not just go back all the way to cable cars?.
I assume they are only used in SF for historical reasons. We used to have them in Melbourne but replaced them with electric trams and overhead cables.
In the last decade or so a lot of devices such as street lights have been installed to run on photovoltaic and battery power. The reason is that a PV power supply is a hell of a lot cheaper than anything which involves digging trenches and running cables.
I am pretty sure that if we did the numbers today the trams in my city would run on batteries and there would not be overhead cables.
I once worked on the traffic signal system in my city. The linking for a block of 120 or so signals was handled by a computer attached to a modem rack by a bunch of ribbon cables. Each cable handed eight channels. On this day I had to pull all the cables out of the modem rack and the piled up at the bottom. When finished I hooked everything up again and powered the system up. Every signal site in the system went to flashing yellow. I actually stepped out of the building to see what I had done to the surrounding suburbs. Not pretty. So I slunk back into my workplace and tried to figure out what had gone wrong, quickly. It took about five minutes to find. I had missed the bottom modem enclosure because it was covered by spooled cables. The cables for that row were in the row above and so on. Having fixed that all was okay except I had come close to a heart attack.
We bought new alpha servers and the old VAXs went out the door. This created space in the computer room for a small office where we could build things and keep track of stuff. So corporate building services found a contractor to build our new office. One day I found him in the computer room cutting aluminium with a circular saw and spraying the resulting metal filings all over the new alphas and their associated VT320 terminals. I went mediaeval at him. Told him to stop. Got the boss. He went mediaeval at the guy, rang building services. They said well has anything broken yet? If we tell him to do it in the car park he might walk off the job.
I bet the S Koreans have a production line which could churn out a bus per day. These guys think large scale. They built a whole new island for Incheon airport. And its not just the airport on the island. Its got its own city and transit system.
Its hilly and congested. Many major roads are pretty much gridlocked. Urban speeds are quite slow. Many roads are steep. Motors which don't use energy when stopped are a great idea. Regenerative braking is also worth while.
How did Sony fuck up such that this story is not the biggest breakthrough in cryptoanalysis since frequency analysis?
Its not that big a deal for them. People will still buy their consoles. Software publishers will still pay Sony for the signing keys. They don't lose much if home users can load their own software.
Its the old DRM argument. You don't have to crack the crypto. You just need to extract the private key from the PS3, which you own. If you only had the signed software (the message), obtaining the key really would be hard.
When I learned to ski my dad taught to point a ski pole at anybody claiming to be out of control while mowing me down. I have used it several times and they always learn to steer immediately.
Yes, and when I reach the bottom of the hill, I would beat you senseless.
A French guy told me once that the local government which controls the centre of Paris has an ongoing battle over traffic with authorities who control roads in surrounding areas. Nobody wants the through traffic so this central part of Paris keeps coming up with schemes to make their roads unattractive, while not pissing their own residents off too much.
Most drivers in Paris knows how to park well without bumping, those who do that are mostly tourists (were you one of them ?) and old men who should'nt drive (i live there)
I never drove in Paris. In fact I have been driving in Australia for so long that the mere thought of driving on the right gives me the horrors.
Drivers in Paris park bumper to bumper and the way to get out of a parking spot is to ram the cars in front and behind of you until you have space to pull out. They drive these little light cars and the bumper bars (US people would say fenders) are all scuffed. My car has a tow bar so you couldn't do that but nobody where I went in Paris seems to use them.
Just one of the reasons why in most European countries the words "inconsiderate prick" are synonymous with "French driver".
My French colleagues assume me that the words "inconsiderate prick" are synonymous with "Parisian driver".

Along these lines my favourite safety feature for cars is a spike attached at one end to the front bumper and at the other end emerging from the steering column. Hit anything and the driver gets skewered.

Its fine at the moment. I haven't looked closely so I don't see how I would go about upgrading. Most of the apps I am interested in installing I build myself.

Or just use cables sliding through a slot in the road. Why don't they do that?
Yes though I assumed that from the title.

There you go, my fuck-up. Want to hear more?

Seoul has an excellent underground transit system. The buses are most likely a feeder service for the trains.
Maybe you can hear the bullet rather than the initial explosion.
You never hear the bullet which gets you.
52 miles could be a days driving for a bus in Seoul.

Why? For protecting myself?

.. and maybe use the power to operate communications or lighting gear.
Hahah I read "lightning gear"
They already carry those but I believe they run on batteries.
The ramming game appears to work well enough.
