  • Basically the anti-DRM stance. If I can buy through GOG, I will do that because I know that edition is not DRM encumbered. In steam it should be optional, but plenty of games that are DRM-free on GOG are DRM-enabled on steam. And while GOG galaxy is Windows-only, at least they do bother to provide Linux installers for some of the library.

    I will grant that Valve are doing a lot more on Linux and ecosystem, with more integrated support and extending the Linux support to cover a lot of games where publishers didn’t lift a finger to enable Lniux. Probably stemming from having a significant more amount of money to work with and freedom from public investors to let them spend as they see fit.


  • I will grant that particularly steam frame I don’t think Valve could have done as a public company, investors would be rioting over the attempt.

    Public companies get heavily penalized for “labor of love” type endeavors.

    Though CD Projekt seemingly does some things I’d have assumed investors would have balked at as well.


  • 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.




  • If the code actually works and is vaguely important, I think you are right.

    If anyone ever has to fix it because it’s also broken on top of being a mess, well they aren’t quite so safe. Maybe if you are always available to fix it same day, but if you ever go on vacation and it hits the fan while you are unreachable…
