Modern Fortran in Science and Technology by Lindemann and Dahlblom

[Beliavsky]

Modern Fortran in Science and Technology could be added to the Online Courses section. I skimmed it, and it seems pretty thorough.

Yes, we should. Although the first place I randomly clicked: https://modern-fortran-in-science-and-technology.readthedocs.io/en/latest/chapter_fortran.html#arrays-and-matrices and it has a mistake, they assign 5.0 to a double precision number, which will only assign the first 7 digits or so instead of 15.

[Beliavsky]

They are aware of this and illustrate this issue with a sample program

program constants
    implicit none
    integer, parameter :: dp = selected_real_kind(15,300)
    real(dp) :: pi1, pi2
    pi1 = 3.141592653589793
    pi2 = 3.141592653589793_dp
    write(*,*) 'pi1 = ', pi1
    write(*,*) 'pi2 = ', pi2
    stop
end program constants

but maybe some of the code they present could be improved -- the book is on GitHub

Ok, I submitted a PR: jonaslindemann/modern_fortran_book#1

[jonaslindemann]

I will look into the issues.

I hope I have fixed it in most places.

Thanks for the input.

Thanks @jonaslindemann!

Yes, we should link it.

Btw, currently when I open the page: https://modern-fortran-in-science-and-technology.readthedocs.io/, I am getting "Warning: Potential Security Risk Ahead" in Firefox and Chrome and it does not open for me. It could be an issue on my end.

I just tried with FireFox myself and had no such problem. Op di 29 jun. 2021 om 15:48 schreef Ondřej Čertík ***@***.***

I don't have any problems myself. It is built and hosted automatically by readthedocs using Sphinx. Thanks for linking it by the way!

No problem with MS Edge either, so it seems indeed to be on your side (or it is a temporary thing) Op di 29 jun. 2021 om 15:50 schreef Arjen Markus ***@***.***

Perfect, I am glad it is only on my end. I'll try again in a few days. I also tried from my phone and that worked.

Lindemann has uploaded to YouTube a series of videos on Scientific Programming in Python and Fortran that could be listed in the Online courses section.
