    Why should the ideal temperature be right in the middle of the range?

    It’s no surprise that the maximum end of the range is right around the body temperature, as it’s difficult for the body to keep itself cool once the environment is around or warmer than the body temperature. Sure, we can sweat, but that uses up a lot of water and people generally find that getting all sweaty to not be pleasant. Run out of water or raise the temperature too much and it gets dangerous pretty quickly.

    On the other hand, if the environment is a lot cooler than the body temperature, then it is difficult for the body to keep warm. I’m sure for our distant ancestors who lived in what is now Africa, their minimum temperature was much higher, possibly putting the ideal temperature right around the middle of their range. Luckily for us, we have clothing and can put on more clothing to stay warm, which is how we can now make the minimum so low. But while we can use clothing to lower our minimum, we really don’t have anything different to raise our maximum vs. our ancestors - we’re both limited by how well we can cool ourselves by sweating. So for that reason it doesn’t really surprise me that our ideal temperature is towards the upper end of what we consider the minimum and maximum temperatures.

    Actually, it’s the other way around. 100 degrees F weather is really hot. Driving 100 MPH is really fast.

    In metric we have 40 degrees C weather is really hot, and driving…uhhh… (gets out a calculator)… 160 km/h is really fast.


  • I can see it. My corporate work laptop is locked down with their security and monitoring software, so I’m not using it for personal things, even if it is allowed for some limited things. And there’s company resources that I can only access through the machines under their control, so I couldn’t ditch it either. And using that laptop for a second job would be a big no-no.

    I can see the school laptop being similar, though my experience is that they tend to not be locked down quite as hard as the corporate machine, unless you do boneheaded things with it and piss off the school’s IT department.

    So I can see the need for a personal computer, plus it’s always nice to keep that well separated to avoid things like incidents hooked up to a projector and screen sharing.






  • Not too long ago, on a Slackware box I needed to manually change glibc to another version. No problem, I thought, just remove the version that’s there and install the package for the version I needed. So removepkg glibc and then immediately dawned on me… oh wait I really didn’t want to do that… Of course, after that installpkg and pretty much everything else was broken since pretty much everything either depends on glibc, or has a dependency that depends on glibc, so I couldn’t install the new package or do pretty much anything other than smack my forehead.

    Wasn’t actually too big of a deal to fix. Used another computer to create a bootable USB stick with the Slackware installer, booted the computer with the USB stick, and did some chroot trickery to reinstall the old glibc package again. Then booted it back up normally and used upgradepkg to change glibc like I should have in the first place.
