International Classification of Headache Disorders 3rd edition
by the International Headache Society
 
  
This software is the electronic version of that English classification of which it scrupulously preserves every aspect. A simple mouse click allows selection or deselection of diagnostic criteria, which are then automatically analyzed in search of the most appropriate diagnosis. One can thus use the classification tout court or select the diagnostic criteria from a special form and have the software search all the chapters for them in the various headaches.

Classical Cryptology at play

Version IX-MMXXIII
for Windows (32 - 64 bits)

Cryptography takes the lion's share, but I will add cryptanalysis as soon as possible in a more complete and comprehensive form.
