  • Ich habe gelernt, das bei Lichtschutzfaktor 15 etwa 7 Prozent der Sonnenstrahlen an die Haut gelangen, bei 30 nur noch 3,5 Prozent und bei einem Lichtschutzfaktor von 60 wiederum nur noch die Hälfte. LSF 30 oder 50 macht in der Realität also keinen Unterschied mehr, das ist nur noch Marketing.

    Korrekt. Ander formuliert kann man auch sagen, dass Lichtschutzfaktor X bedeutet, dass jemand mit Sonnencreme X Mal so lange draußen sein muss um die gleiche Dosis UV Strahlung abzubekommen.
    Also 5 Minuten ohne Sonnencreme sind equivalent zu 5 Stunden mit Lichtschutzfaktor 60.







  • It provides the capability to authenticate yourself online, e.g. for banking services. It would also be able to prove to a website that you are over 18, without telling the website your birthday. I have yet to use it, but from a technical standpoint it’s pretty awesome.

    Edit: to clear up some confusion that may exist: as far as I know the app provides the bridge between the chip in the ID card and the application that needs the authentication. No data needs to be stored in the app.










  • I have never seen banding before, the image seems specifically picked to show the effect. I know it’s common when converting to less than 256 but color, e.g. if you turn images into svgs for some reason, or gifs (actual gifs, not video)

    Also dithering exists.

    Anyway, it’ll surely be standard at some point in the future, but it’s very much a small quality improvement and not something one definitely needs.

    A basic image is really easy. It’s basically just

    Dockerfile

    FROM debian  # start with a minimal Linux system. There are probably better options than debian. Some images are made especially for docker (i.e. very minimal and light weight). 
    RUN apt install dependencies  # do what ever you need to get your app running. 
    RUN echo "options and stuff" >> /etc/a/config/file  # you can also edit system files
    COPY . /app  # copy your project into the docker container.
    EXPOSE 8080  # doesn't actually do anything, but documents where the app will be listening
    CMD server-binary run /app/main.php  # I have actually no idea how php server stuff works
    

    (Docs https://docs.docker.com/reference/dockerfile/)

    Then people can run your project with docker.

    Edit: checking the readme some small changes would be required. Config.php should read in environment variables and the DB init SQL should be run automatically somehow.
