For me the more interesting presentations (based on the titles) are:
4. Eugen Antal, Pavol Zajac and Otokar Grošek: Cryptology in the Slovak State During WWII
5. Dermot Turing: The Typex Scare of 1943
6. George Lasry: A Practical Meet-in-the-Middle Attack on SIGABA
I hope they post their proceedings at their site like last year.
