  • Well that screenshot was accurate for Gentoo circa 2005, it’s just the worst choice for ease of install, with Linux graphical installs provided by suse, mandrake, and redhat from the 90s.

    Fair point could be made that the out of box experience was sorely lacking and you pretty much had to configure;make install most software you actually wanted…


  • That’s a good point, also if you can compare like to like conditions and what the data does if you exclude teen drivers. Also if you can identify incidents related to bald tires and brake failures that wouldn’t apply.

    Also would be interesting to compare human augmented driving miles to full autonomous miles. With the automated emergency braking/collision alert/lane centering assist. Anecdotally was teaching my teen to drive. Suddenly a car pulls out right in front of us, zero warning. If that happened to me, with experience on a formerly normal car, I’m pretty sure I would’ve wrecked. However my kids reflex to swerve triggered the cars “evasive steering assist” and did an action movie worthy maneuver, avoiding going off into the ditch and returning just right into the lane after getting around the other car.

    Thing about autonomous driving is that it seems to get the stupid easy stuff wrong in dangerous ways, but if you have a demanding precise maneuver to make, it has a better chance once that maneuver is needed.


  • The challenge is one approach only needs to modify the transit infrastructure. The other means having to tear down and build new commercial and residential properties and force people and businesses to relocate in order to have a vaguely sane transit system. My area desperately wanted to do transit but even with rather significant hypothetical funding, they could only service about 10-15% of typical trips. They’ve settled on a plan that is much less money, but only serves like 5% of trips. To go with that plan, they are making restrictions around zoning to force mid density mixed use construction only, favoring one of the two chosen transit corridors.

    They are trying but just people are distributed very awkwardly for mass transit.









  • While technically the truth, it can be a hassle to make sure you restart all relevant services after updating a given library.

    I just like being able to restart underlying system to take care of any possible straggler without thinking, and the services broadly be provided by multiple systems so the “experience” is starting up through a rolling reboot


  • So assuming 10 lbs of force, as measured 1 meter away from the hinge, you have about 44.5 Nm of torque. Assuming each door opening was about 90 degrees, then you have about 70 Joules per door operating event.

    Each door opening would have a physical theoretical max of 0.02 watt-hours.

    Assuming you spent 8 hours opening a door every 10 seconds constantly, then you have 58 watt-hours of energy at the end of the day if you had 100% efficient generators. One typical solar panel would hit that in under 15 minutes in real-world energy collection, not theoretical.


  • So yes, the law says there is some unavoidable, unusable waste heat, the question is how much of that heat is really unusable?

    For example, you have lava at around 1,000 degrees. You certainly can harvest energy from that, hit some water with it and spin a turbine.

    For the most part, once we get under 100C we run out of ideas on how to realistically harvest energy out of it, but there’s still a pretty good delta between that an ambient. The claim of this article is he has an approach to harvest energy at an even lower temperature delta.

    If it got to harvesting all of the temperature delta of a system, then we can say “not at all possible based on current understanding of physics”, but if the process leaves some waste heat unharvested, then it’s not yet violating that law. The law just says it gets less and less likely as the amount of heat in question diminishes.
