  • "The fact that Google has that locked down surely violates some EU laws. But I’m sure they wave away the laws because of “financial security” or some other bullshit. "

    I don’t know as much as I’d like to about the regulatory side of this, but I know that Google and other big tech have done a masterful job of proactively building themselves into systems such that taking action against them is difficult.

    I think that’s part of why the US antitrust case against Microsoft a few decades ago fizzled out into nothing — even though Microsoft was deemed to have been a monopolist, the big question was how do we remedy that in a way that isn’t going to be harmful? The consensus on this amongst people who I respect is that the results of the Microsoft case was woefully insufficient and something that helped to lay the foundations of the big tech dominance that we see today.


  • When I first got into Android (I miss my Nexus 6 T.T ), it felt like I could do so much more with my phone than I can now. I had so much cool automation shit that leveraged stuff like Google assistant voice commands, but now it’s shit on so many levels. It goes beyond the user facing side of things; I used to use the app Tasker for a lot of the automation stuff, and over the years, it seems like the dev has been climbing an uphill battle against Google gating off functionality, and generally making things opaque and difficult for developers.




  • I don’t typically experience imposter syndrome.

    However, it is my understanding that the majority of people I know seem to experience imposter syndrome (likely influenced by the fact that my social circle is mostly academics)

    Thus I seem to be the odd one out in this respect, paradoxically causing me to feel like an imposter for not experiencing imposter syndrome.

    ¯\_(ツ)_/¯








  • 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.
