Dick Van Dyke turns 100
All Hollywood stars grow old and die except perhaps one – Dick Van Dyke – who turns 100 today. The real world Peter Pan who used to trip over the ottoman on The Dick Van Dyke Show is still standing. The man who impersonated a wind-up toy in Chitty Chitty Bang Bang hasn’t wound down […]

Poor Johnny still won’t encrypt
The state of email encryption This title is an obvious nod to The 1999 article Why Johnny Can’t Encrypt, and The 2006 article Why Johnny Still Can’t Encrypt: Evaluating the Usability of Email Encryption Software.
