    The difference is that humans emit their own heat. Combined with our funny tendency to wear insulative clothing that can asymptotically approach zero net heat exchange with the atmosphere, acceptable temperatures skew wildly towards and beyond freezing.

    Meanwhile, without some kind of acting cooling mechanism, any temp even slightly above fever temp is inevitably fatal. You can only take off so many layers. What are you going to do, take off your skin? Sweating helps us humans a lot, but evaporative cooling can only do so much to reverse the heat gradient.

    50 F is excellent… with a light jacket or a blanket. Not so much if you’re naked.



  • The other day I learned that you can just grep an unmounted filesystem device. It will read the entire disk sequentially like it’s one huuuuge file. And it will reveal everything on that disk… whether a file inode points to it or not.

    Used it to recover data from a file I accidentally clobbered with an errant mv command. It’s not reliable, but when you delete a file, it’s usually not truly gone yet… With a little luck, as long as you know a unique snippet that was in it, you can find it again before the space gets something else written there. Don’t even need special recovery tools to do it, just use dd in a for loop to read the disc in chunks that fit in RAM, and grep -a for your data.

    Yes. On average.

    If you specifically take 100 kilos of core material from the Sun, then it would be a no contest victory for the Sun. But the Sun is very, very big, and when it comes to producing energy, most of it is doing absolutely nothing. So it brings the average energy production per kilo way, way down.

    On the other hand, if you average the Sun’s energy generation across its entire volume and adjust for that volume’s mass, an equivalent mass of human body tissue generates more heat energy.

    So your eyes may not have the raw lumen output of an entire star; but, pound for pound, your eyes would outshine a similarly massive piece of one.





  • For me, multimedia is a non-negotiable part of the web experience.

    Yes, I get as annoyed as the next guy when I want, say, a simple tutorial written in a couple paragraphs, but the only ones anyone seem to want to make are eight minute long videos filled with fluff. That sucks. But purposefully excluding it from your protocol because it burned you a fee times is a gross overcorrection in my view.

    I appreciate the Gemini project, I respect its goals, and I am happy that it meets the needs of several people such as yourself. But for me, and I think for a great majority of people who would be potentially interested in its broader goal of simplifying the web but are dealbroken by lack of multimedia capabilities, Gemini will never be anything more than a toy. A quirky little curiosity that will never expand beyond a tiny clique of people who accept Gemini for what it is and are content to only ever see content from that same small pool of people.
