    This is a FAQ for end users, about a feature in software running on end users’ computers.

    It is absolutely doublespeak to call it “local”. Are we supposed to invent an entirely new term now to distinguish between remote and local? Please do not accept this usage. It will make meaningful communication much harder.

    Edit: I mean seriously, by this token OpenAI, Google, Facebook, etc. could call their servers “locally hosted”. It is an utterly meaningless term if you accept this usage.










  • Speed is less of a factor than endurance in a persistence-hunting scenario where we’re much slower than our prey anyway.

    I don’t know the facts for this specific claim, but the logic is fair. One group can be better suited for endurance without being faster. One group could also be faster on average without having the individual fastest performers. Not only because of cultural factors, but also because the distribution curves might have different shapes for men vs women. There could be greater outliers (top performers) among men even if the average is higher among women in general. It’s not necessarily as straightforward as, say, height, where men’s distribution curve is almost the same shape as women’s, just shifted up a few inches.

    I don’t have the data to draw any real conclusions, though.

    One of the problems looking at athletic records is that it’s really just the elite among a self-selected group of enthusiasts, which doesn’t tell us a whole lot about what might have been the norm 100,000 years ago, or what might be the norm today if all else were equal between genders. These are not controlled trials.

    I’ve read that the top women outperform the top men in long-distance open-water swimming, supposedly due in part to higher body fat making women more buoyant, helping to regulate body temperature, and providing fuel. This is the first time I’ve read that women might have an advantage in running, though.

    I wish the article provided citations. The reality is probably too complex to fit into a headline or pop-sci writeup.



  • I keep seeing this claim, but never with any independent verification or technical explanation.

    What exactly is listening to you? How? When?

    Android and iOS both make it visible to the user when an app accesses the microphone, and they require that the user grant microphone permission to the app. It’s not supposed to be possible for apps to surreptitiously record you. This would require exploiting an unpatched security vulnerability and would surely violate the App Store and Play Store policies.

    If you can prove this is happening, then please do so. Both Apple and Google have a vested interest in stopping this; they do not want their competitors to have this data, and they would be happy to smack down a clear violation of policy.







  • Probably ~15TB through file-level syncing tools (rsync or similar; I forget exactly what I used), just copying my internal RAID array to an external HDD. I’ve done this a few times, either for backup purposes or to prepare to reformat my array. I originally used ZFS on the array, but converted it to something with built-in kernel support a while back because it got troublesome when switching distros. Might switch it to bcachefs at some point.

    With dd specifically, maybe 1TB? I’ve used it to temporarily back up my boot drive on occasion, on the assumption that restoring my entire system that way would be simpler in case whatever I was planning blew up in my face. Fortunately never needed to restore it that way.



  • I don’t think there’s any way to count years without rooting it somewhere arbitrary. We cannot calculate the age of the planet, the sun, or the universe to the accuracy of a year (much less a second or nanosecond). We cannot define what “modern man” is to a meaningful level of accuracy, either, or pin down the age of historical artifacts.

    Most computers use a system called “epoch time” or “UNIX time”, which counts the seconds from January 1, 1970. Converting this into a human-friendly date representation is surprisingly non-trivial, since the human timekeeping systems in common use are messy and not rooted in hard math or in the scientific definition of a second, which was only standardized in 1967.

    Tom Scott has an amusing video about this: https://www.youtube.com/watch?v=-5wpm-gesOY

    There is also International Atomic Time, which, like Unix Time, counts seconds from an arbitrary date that aligns with the Gregorian calendar. Atomic Time is rooted at the beginning of 1958.

    ISO 8601 also aligns with the Gregorian calendar, but only as far back as 1582. The official standard does not allow expressing dates before that without explicit agreement of definitions by both parties. Go figure.

    The core problem here is that a year, as defined by Earth’s revolution around the sun, is not consistent across broad time periods. The length of a day changes, as well. Humans all around the world have traditionally tracked time by looking at the sun and the moon, which simply do not give us the precision and consistency we need over long time periods. So it’s really difficult to make a system that is simple, logical, and also aligns with everyday usage going back centuries. And I don’t think it is possible to find any zero point that is truly meaningful and independent of wishy-washy human culture.
