    One time, I was in the arctic doing some research. On a snowmobile, in winter, we crest a hill and see a couple of wolves pigging out on a caribou. I’m riding in the toboggan, and I start telling at the driver: “go go go!” They proceeded to chase our snowmobile for like a mile, with no hope at all of catching us, but running anyway. Like dogs chasing tires, I think they had no choice. Instincts are strong.














  • I’m sorry you had a bad experience. I’ve used it as my daily driver with minimal effort post installation on multiple occasions, usually on work laptops where time spent tinkering is time wasted. I’ve found it to be a good choice in that context. I now own my own business, and OpenSuse has allowed me to repurpose older laptops as workstations for my employees with minimal effort.

    The only actual pain point I’ve seen is setting up a wifi enabled printer … required that I change my firewall zone so the printer could be discovered. And that only required a few minutes to figure out. The fact that the firewall is set to a more secure default is probably a feature, not a bug.

    I don’t think melting is the issue here. I think it literally disintegrates at those speeds. Like, this is Mass Effect mass driver level of impact with the atmosphere.

    For reference, RICK ROBINSON’S FIRST LAW OF SPACE COMBAT: “An object impacting at 3 km/sec delivers kinetic energy equal to its mass in TNT.”

    Assuming the lid is travelling 55km/s, it’s well beyond that point. The atmosphere it’s travelling through is basically a solid at that speed. Even if it isn’t heating due to the friction (and waiting for heat flow), it is heating due to the compressive force of being slammed into the atmosphere. It’s very likely the whole thing vaporized.

    But I could be wrong, and some alien SOB is going to have a bad day when the manhole cover slams into their ship in interstellar space.

    I rarely judge someone for ignorance unless it is wilful. I pretty harshly judge people who cannot assimilate new information. Over time I think I might be evolving from INTP->INTJ as I age. I used to have more patience and would try to encourage people to learn and adjust.
