Fortran 2023

I learned Fortran for a summer research job in college about 15 years ago. It was my first programming language and I used it to do some population modeling. I found an old Fortran book from when my dad went to school back in the early 70s and learned it from that which was a cool experience - I just had to skip over all the parts about entering your code into punch cards :D

Besides the technical part, Fortran&#x27;s community has evolved a lot as well since 5-10 years. See the community paper here: <a href="https:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;2203.15110" rel="nofollow noreferrer">https:&#x2F;&#x2F;arxiv.org&#x2F;abs&#x2F;2203.15110</a> &quot;The state of Fortran&quot; (not an author myself)

F’23 doesn’t have much in it that’s new over F’18, which itself was also a pretty minor update to F’08.<p>One thing to watch out for: in a departure from former commitments to compatibility, F’23 changes some semantics of working conforming code, specifically allocatable characters being used for internal writes, iomsg=, &amp;c.

For a summary of changes to the language, see John Reid&#x27;s slides here: <a href="https:&#x2F;&#x2F;fortran.bcs.org&#x2F;2022&#x2F;AGM22_Reid.pdf" rel="nofollow noreferrer">https:&#x2F;&#x2F;fortran.bcs.org&#x2F;2022&#x2F;AGM22_Reid.pdf</a><p>More info, The Home of Fortran Standards: <a href="https:&#x2F;&#x2F;wg5-fortran.org&#x2F;" rel="nofollow noreferrer">https:&#x2F;&#x2F;wg5-fortran.org&#x2F;</a>

Hooray! But I’ll stick to fortran77

hmm, wonder which fields people are using fortran now ?<p>did a search, ha<p>- numerical weather prediction,<p>- finite element analysis,<p>- computational fluid dynamics,<p>- geophysics,<p>- computational physics,<p>- crystallography and computational chemistry.

Just in time for Advent of Code.

Is anyone aware of a nice resource that teaches the language while also showing its evolution at each step?<p>(as opposed to just teaching the latest version only &#x2F; an older version only)

Numpy probably calls Fortran and C libraries under the hood.<p>Is Fortran still considerably faster than Numpy?

Ok. but can I create full stack webapps using Frontend?

Absolutely wild to me that you need to buy access to a <i>digital PDF</i> of a spec for a programming language in 2023.

Stupid ISO charging money for standards.
