"Another notable change is the re-emergence of Fortran in the index at 20th position, up from 34th spot a year ago. Fortran, which emerged from IBM in the 1950s, remains popular in scientific computing. Its highest ranking on Tiobe's index was 10th in 2002.

Fortran was the first commercial programming language ever, and is gaining popularity thanks to the massive need for (scientific) number crunching. Welcome back Fortran.

The top 20 programming languages this month were: C, Java, Python, C++, C#, Visual Basic, JavaScript, Assembly language, PHP, and SQL, Classic Visual Basic, Delphi/Object Pascal, Ruby, Go, Swift, R, Groovy, Perl, MATLAB, and Fortran."

Noticed Fortran almost beating MATLAB which is on 19th place ?

To surpass it we need
- perfect %pl (must be publishable quality by default)
- add surfaceplot
- add 3D plot (OpenGL)

I have surfaceplot and OpenGL implemented, they are not difficult to do

Also
- perfect run speed on Polyhedron tests
- add Wininet (sockets)
- add support of OpenMP and create examples
- add support of HDF5 + examples

Dan you intrigued me with "surface plot". Is this a routine that uses "Z" data in addition to an X and Y to interpolate thicknesses at various positions?

Bill
Yes. In simple form it is like here. Done with current %GR quarter century ago. Same can be done with %PL



in more complex like here. Bottom is 3D, top - surface plot. Essentially it is 2D plot in 3D. Both done in OpenGL. Difference in programming almost zero



I published sources demo many times here. With OpenGL the only what's left is to add numbering like in the 3D picture. I modified existing OpenGL example supplied with Silverfrost Examples without even learning OpenGL

Other examples. Surface plot at the bottom


Good to add a pie chart

You sent me these OpenGL examples to use for learning some of the ins/outs of OpenGL. Much appreciated.

I am not sure what to make of it when Assembler is in the top 20.

this programme rating mularkey seems to be based on search engine results !
not very 'scientific' imho !

assuming that most people/searches are related to bad understanding/problems running a language, the top languages are maybe mostly the most difficult to use !?!

see more here (page referenced in the main article Dan gives the link to)
https://www.tiobe.com/tiobe-index/programming-languages-definition/

maybe this explains Robert's astute comment above ?!

Assembler became popular lately because of extensive use of testing by everyone on the net. Beating competitors just by the factor of 1% immediately makes you the winner of universe and all others bite the dust.

Can the Polyhedron tests be disassembled to understand why gfortran and IVF sometimes beat by the factor of 2-5-10 and even 30?
