So, one-letter English labels were deemed bad coding-style for decades, but suddenly one-letter Greek labels are good because some X-language (Julia) supports it. Seriously? How about single-letter Chinese labels? because that is my backgro

Julia does not have offset arrays. There is an external Julia package that can mimic Fortran's intrinsic behavior (arbitrary start index).

I doubt your baseless doubt. What do you mean by outdated? do you mean those decades-old features like "modules" that other "modern" languages (like C++) are now adding in 2021? Or do you mean vectorized array syntax tha

You can write bad code in any language. The verbosity and restrictions of (modern) Fortran standards leave significantly less room for developer mistakes, much better than C/C++.

The fact that Fortran applications are not collected in a single page by a for-profit company that does not exist in the case of Fortran, does not in anyway prove that new applications moving away from Fortran.

Fortran is quite heavily used in computational science domain. Both the "old" (F66, F77, F90) and the new modern F2003, F2008, F2018. and Yes, (modern) Fortran feeds my family daily (along with many other computational tools and s

Fortran is NOT a systems programming language. It is a niche language for scientific computing and why it is called (mathematical) Formula Translator (a.k.a Fortran).

Actually, at least Cray, Intel, and NAG Fortran compilers already fully support Fortran 2018 standard.

The literal constants in this code are not in double precision and the results will not be accurate up to 64bit representation. Also, Fortran compiler optimizations can change the order of computations to generate the result faster. This do

The Fortran standard is deliberately silent about the passing method. However, virtually all Fortran compilers pass by reference.

C++20 added modules to the language more than 3 decades after Fortran had it already in the language.

Did my original post even mention RecursiveFactorization.jl or DifferentialEquations.jl? (or is this an implicit package promotion? I do not have issues with them anyway, perhaps great work, have not used them...) Regarding your second poin

Julia has a long way to get there, where Fortran is in terms of stability and maturity, needs approximately 60 years more.

The problem with Julia is that there is so much hype around it, likely because of the for-profit company behind Julia. I see a non-negligible number of false claims and false promises on Julia's performance on the web every now and the

Can you elaborate on why it "is actually better to program in than Fortran"?

Fortran is a fully-vectorized and parallelized language at all levels, from instructions to shared and distributed parallelism (corresponding to one-sided MPI communications). This has been the case for at least 3 decades if not more. There

For heavens sake, let's stop the discussion of Fortran array index starting at 1. In Fortran the starting index can be anything. A(-10:-5) is valid, A(-10:10) is valid, A(1:10) is valid, A(0:10) is valid. Choose what you want and do no

Fortran has been using `int8`, `int16`, `int32`, `int64`, and `real32`, `real64`, `real128` kinds officially for at least 2 decades. `double precision` has been long declared obsolescent, although still supported by many compilers. Regardin

Modern Fortran (2008/2018) syntax is a bliss. You would almost not notice if your are coding in MATLAB or Fortran with the advantage of your code being orders of magnitude faster in Fortran. Those who criticize the syntax of Fortran ha

There are occasions where globals cannot be avoided.

actually Numpy and MATLAB try to mimic the high-level behavior and syntax of Fortran.

There are many new projects in modern Fortran. Just search GitHub.

I could never become a fan of APPLE products. A selfish company that wants to have control over every aspect of the customer's digital life. If I want to develop a software, I have to be a registered developer with Apple. If I am a use

But even "relatively straightforward idiomatic code" is highly opinionated and developer dependent. For example, the array operation `a(:) = b(:) + c(:)` is very well known to be slower (and much uglier) than `a = b + c` in Fortra

The Fortran implementation that I see on GitHub, is in no way the most optimized implementation that one could have, or would do in any serious heavy numerical computation. Yet it is amazing to see how well Fortran performs given all the la

If you read the discussions to end, you will notice many objections to the benchmark that you have posted here. Even I have objections. -O3 is not the end of all possible optimizations in C and Fortran.

Yes, it is still heavily used in the world of numerical computing. Many of the world's largest numerical software have been written in Fortran and are still developed in Fortran, although Fortran is not alone anymore in the field and e

Modern Fortran is a bliss, very high level comparable to MATLAB and Python, yet lightening fast, only a professional careful C programmer could get to its speed. Meanwhile, the only high-level programming language that provides a very simpl
