Comment Re:Will they be cut off after 6mo-1year (Score 4, Funny) 157

You will get new versions of a car :
- Home basic car : will only start 10 times, until you get an upgrade. Can only take a single passenger
- Home premium car : start always, but there are no brakes
- Profesionnal car : has brakes, but they break often
- Enterprise car : has reliable brakes, but lacks a radio
- Ultimate car : you get the radio for 5000 Euro extra.

I have to put the obligatory GM-Microsoft :

>> What could possibly go wrong?
Nothing. There are hardly any firewalls between ECUs. Firewalls do not exist on CAN.
The article is written by someone with no insight in car architecture :

>> First, however, carmakers must deploy more open OS platforms
Nothing to do with the reflashing

>> remove hardened firewalls between vehicle ECUs
There aren't any firewalls

>> and deploy networking topologies such as Ethernet, with proven security.
Ethernet is already widely deployed in cars for data hungry applications ( infotainment) For other uses, ethernet is absolutely not suitable ( price, power, wiring constraints, EMC, safety, .....)

Yep. If systemd lacks a good init system and emacs lacks a good editor, just integrate emacs in systemd.

By the way, in french, "systeme D" means bricolage ( making something work by slapping together the things you have lying around)

Comment No critical mass (Score 1) 282

>> , an NTP rocket could generate 200 kWt of power using a single kilogram of uranium for a period of 13 years
That is wrong. A single kilogramm of Uranium can not do much. The critcal mass is 56 kg.
And that's for a perfect sphere of highly enriched U235. With this configuration it's also a nuke bomb, not really an effective means of travel in one piece.

For a nuke reactor operating reasonably, you need 500 kg/ many tons of uranium.
And that's a risk to the whole mankind to put that in a rocket. A launch failure with a ton of fissile material would realistically kill everyone on earth.

That's the signe reason why this was not done in the first place.
