Programming

This is my collection of algorithm, tutorials, classes, objective-c and fortran codes. It still incomplete but I plan to upload all as soon as possible. You can use, for free, each codes but please put a small credit in your project with the link to this blog. You can also modify, adapt and make a better version of all. Remember to send to me a mail if you want to share it to others.

- il linguaggio Fortran 90/95: a complete book (in italian) on Fortran 90/95 language. FORTRAN is not a dead language, the majority of programs used and developed in the scientific and engineering communities are still written in FORTRAN 77 or Fortran 90. High-performance computing is mostly done in one of the parallel dialects of Fortran. This guide concentrates on topics which are not discussed in ordinary Fortran courses and regular textbooks: good programming practics, and various technical and numerical issues.

- The application we’ll build in this paper is a factorial calculator, i.e. a simple Cocoa program that evaluate the factorial of a positive integer number. The aim of this tutorial is to equip you with an understanding of the concepts and technique needed to get started with writing Cocoa GUI applications. The aim of this other tutorial is to provide, conversely, an introduction to the Objective-C programming language and object oriented programming. You’ll learn to define your own class, create objects or instances of that class and send messages to those objects.
- Calculator : a simple calculator writed in Cocoa and Objective-C languages. Informations and source code can be found here.

XFoil: is an interactive program for the design and analysis of subsonic isolated airfoils. Here you can find a simple step by spep tutorial (in Italian). These are simple instructions on how to create a file that saves the 2D viscous drag and lift polars using the XFoil program available from Mark Drela of MIT. These instructions are a useful way to reduce, I hope, the steep curve associated with learning XFoil, and they should be used in conjunction with the official instruction manual available on the XFoil website.
Here you can find simple step by spep tutorial (in Italian) for XFLR5 (an analysis tool for airfoils, wings and planes operating at low Reynolds Numbers).
