    I think it’s best to encourage people to go see professionals if they suspect they might have a disorder or any kind of illness. But I think it’s detrimental to tell them they are just imagining things as this might lead to serious issues flying under the radar.

    Let the people decide who studied this.

    it is wrong to want to be spoonfed your computing needs

    Why though? It’s not like you are building your own OS every time on assembler level, or do you?
    Making software more convenient is one of the reasons for having software at all.

    That doesn’t mean turning it into an “opaque box” where company interests will be pushed. Having a more user experience oriented design in Linux distros can save a lot of time and frustration as well as make it more attractive to average users. Even power users, who work with Linux professionally will benefit.

    And it just might start with something as simple as proper documentation of a package.



  • In case you are serious or someone else is serious about this:
    Masks, just like underwear, are permeable. If they wouldn’t be, you would suffocate as no air would be able to reach your lungs. (At your rear, that’s just a consequence of low requirements towards the material, which mainly serves as a covering and being able to dry.) So gas molecules are usually not stopped to pass through your underwear or masks.

    The main difference between, e.g. FFP2/3, masks and your underwear is the size of particles that are able to pass through. Your underwear will be able to catch some moisture of a juicy fart and probably some shit particles. However, most of the gases and smaller particles can pass through. Filter masks are able to stop most particles down to a certain size. For FFP 2 masks at least 94% of particles down to a size of 0,6 micrometers can be stopped. Particles smaller than that are likely to pass through. FFP 3 masks block at least 99% of particles down to the same size.

    The thing with viruses like Covid-19 is, that they are usually expelled from an infected person via the respiratory system, that means, your mouth and nose. There, the virus cells are mostly soluted within the moist air you breathe out. Moist air means: there are very tiny (mainly) water particles which are spread over a certain volume of gas. And they are floating with the currents of the gas. That’s what basically constitutes an aerosol. Particles, tiny and lightweight enough to float with a gas (for a while).
    You can see that clearly with spray cans. With breathing air it’s not so good to see with the naked eye.
    Those moist particles, loaded with virus cells, are usually large enough to be filtered out by FFP masks. It’s not perfect of course, but it can help a great deal and contribute to prevention measures.

    The stinky stuff in farts is afaik a pure gas and not an aerosol. (Did you know that in terms of gas volume, just about 2 % of a single fart contains the smelly chemicals?) Which is why neither masks, nor underwear help so much against stinky farts.

    FFP masks are mandatory in jobs where dangerous smaller particles can enter your body. They help against dust, smoke and a lot of aerosols. But they don’t filter out pure gases. That’s what gas masks are for.

    In terms of infection spreading, a neat side-effect of masks is that they can slow down the velocity of exhaled air, which helps to reduce how far the aersol spreads around a person. Trying to blow out a candle while wearing a mask isn’t as easy as without a mask, which demonstrates this effect.

    Futhermore, there has been a study suggesting that wearing a mask for a while or wearing it during rainy weather can - up to a certain point - further improve the filter capabilities of such face masks, since the moisture accumulates on the surface of the mask (in- and/or outside) and by this forms another protective barrier.

    Thanks for coming to my TED talk.







  • In seinem Land würden Menschen von Elefanten angegriffen und totgetreten, Dörfer verwüstet und Ernten vernichtet. Die Jagd sei ein wichtiges Mittel, die Überpopulation zu regulieren.

    Das klingt echt blöd, aber was ist denn hier “Überpopulation”? Ist es nicht so, dass in einem fumktionierenden Ökosystem Selbstregulation der Artenpopulationen vorliegt?

    Z.B.: Gibt es mehr Rehe, gibt es weniger Pflanzen, gibt es mehr Wölfe. Dann gibt es weniger Rehe, deswegen weniger Wölfe, aber wieder mehr Pflanzen und dann wieder von vorn.

    Keine Ahnung, ob das wirklich so simpel ist. Bin kein Biologe. Wer es besser weiß, darf gerne korrigieren.

    Ansonsten verstehe ich hier “Überpopulation” eher als “Problem für Menschen”, weil sie Dörfer verwüsten und Co.

    Aber deswgen die Tiere systematisch ermorden klingt auch eher wie eine Verzweiflungstat statt bedachtem Umgang. Genauso könnte man sagen, dass man halt mehr Menschen umbringen müsste, damit es nicht so oft zu Konfrontationen kommt. Pech für Elefanten, dass wir Menschen am längeren Hebel sitzen.

    Wieso nicht Maßnahmen finden, um das Zusammenleben zu harmoniseren? Z.B. Siedlungen besser absichern, die Tiere ggf. in bestimme Reservate bzw. Naturschutzgebiete “sperren”. Sicherlich gibt es noch bessere Ideen, die das Problem gewaltarm lösen könnten oder nicht?
