  • Doesn’t it only work if you then return to a lower altitude? I wonder how long the benefits last for.

    Now that I think about it, I don’t actually know how this even works. Well I know what I’m going to go read about next.

    Edit: My findings:

    • At high altitude, cardiac output (the overall rate of blood pumped by the heart) increases, largely due to increased heart rate. This increased heart rate reduces as one acclimatises to high altitude (though I’m unsure of if it returns to baseline. It appears to be complex, and at least somewhat differing person by person. These individual differences may explain why some people experience health problems at high altitude, beyond the initial ill feelings caused from first arriving somewhere that’s high altitude)

    • The stroke volume (volume of blood pumped by each beat of the heart) is lower at high altitudes. This does improve as one acclimatises, but not entirely. This seems to be affected by blood pressure stuff, such as reduced plasma volume at high altitude. It seems to be complex enough that we don’t fully understand how the various regulatory stuff works.

    • Most of the acclimatisation occurs by increasing the number of red blood cells in the blood. The hormone erythropoietin, which usually exists at a low level in non-hypoxic conditions, stimulates the production of new red blood cells. At high altitude, the level of erythropoietin in the blood rises to around 1000 times its baseline level. Increased production of red blood cells happens for a few weeks, by which point, there is enough to make up for lower oxygen levels at high altitude.

    • When returning to low altitude, it appears that the changes back to the baseline happen over a similar timeline.

    Tangential fun fact: a red blood cell has a lifetime of around 4 months. A single red blood cell travels around 400 miles before it is old enough to be recycled by the body.

    Only a couple. I can imagine that “the user is not the enemy” may be a difficult sentiment for some people with heavily user-facing roles. I’m curious what federated service you’re interfacing with this from. I imagine that’s why you didn’t see the votes on your comment. I am posting this via Lemmy








  • I like that having a controller gives me more versatility in my seating position when gaming. At my desk, I can use either the controller or mouse and keyboard. If I get tired in that position, the long wire on my controller means I can sit elsewhere and play (my desk is positioned such that I can just rotate my monitor and play it from my sofa if I want).

    I also enjoy that a controller is more portable than my mouse and keyboard for playing games on my laptop when away from home.


  • I find the wide variety of ace experiences super interesting. For my part, I’m bi and also demisexual (and I have been working hard at practicing not ace-erasing myself).

    An example of the interesting variety I mean is how libido and attraction aren’t necessarily coupled, and also that even besides those factors, there’s a spectrum of ace attitudes towards sex. I had a friend who had a high libido, but was also quite sex-repulsed. That is to say that she masturbated plenty, but had no inclination towards sex. This caused some tension when she entered into a romantic relationship with an allosexual woman who had some difficulty understanding an ace person being both sex repulsed and high libido (though tbf, my friend was learning how to navigate the line between enjoyable cuddles and unpleasantly sexual stuff. She also tried to fit into the model of aceness similar to what you describe, but she found that her discomfort with sex was such that it made her feel less close to her partner (in contrast to how our sex-ambivalent ace friends had described their experiences).


  • The early-mid game is one of my favourite gaming experiences of all time. It’s usually the most part of a survival/crafting game, but I was surprised by how well Subnautica was peppered intrigue.

    As you and many others on this thread have said though, a mobile port seems odd. Even if the UI were reworked, I can’t imagine that players would be able to feel the same sense of awe that I associate with the game.


  • I disagree with the “complaining about young people” line having coolness increase proportionally with age: when I was a young adult, I often joked about kids these days in a way that seemed to get a lot of laughs. The humour was in the fact that I was a young person talking about young people as if I wasn’t one of them (and beneath that was me making light of the text that, likely due to being autistic, I have always felt isolated from my peer group).

    Anyway, I got good at leveraging this for humour, but as I aged, the joke potential expired: I was too old for there to be any irony in saying “kids these days”, but not old enough for it to be cool to complain about young people.

    On the bright side, I am sufficiently old to be able to torment young people by misusing their slang. It’s most likely effective if you use the slang in a mostly right way, so I enjoy the challenge of needing to actually understand correct usage of new slang. Amusingly, studying current slang as an outsider is a skill I’m well versed in, given that I had to do this even when I was young.


  • The thing about labels is that their usage depends on the particular context at time of use. I have a friend who is non binary, for example, but finds herself weary of explaining how someone can be femme presenting, use she/her pronouns, and be non binary. This means that when talking to people who aren’t LGBTQ, she finds “lesbian” is the most effective label to communicate, even though it’s a label she has largely outgrown the truth of. For some people, how they engage with identity labels is quite straightforward, and they present the same labels out to the entire world. For other people, more nuance is needed, and that’s okay too.

    That is to say that if you read the above comment and thought “bi but with a type sounds like me, but I don’t want to call myself bi”, that’s fine. Labels like “bi” can help make oneself be more legible to the world at large, but you do not owe the world that. You are allowed to have complexity that doesn’t neatly fit into simple labels, and even if you did strongly identify with a label, you’re not obligated to divulge this freely.





  • I wonder if the poor legibility is part of the point. I would not wear an outrageous t-shirt such as this in public, but I would be even less likely to wear a more legible version — precisely because more people would be able to read it. Poor legibility may evoke curiosity in some people who are too far to read it, and perhaps even result in a humorous surprise when someone who could not originally read the text moves close enough to read it.

    Smaller text feels like a whisper, and maybe that’s the effect the designer was going for
