comment Is it possible to construct a passively self-destructing message?
@kojiro The message is something, the media is another. The message is "Hello world", once you read it, I just can avoid that you spread it if I prevent you talking to anyone else. Except in a very restrict environment, where anyone who has access to the message dies or is isolated from the humanity, any time someone has access to the message, you lost control over it.

If they go after the app name, don't think that there is any easy method on changing you app name every time to fool their app.

comment Girlfriend just sent Personal info over email
She wanted to send those documents, and sent them to the right person? Or she sent the wrong documents? Or to the wrong person (although not an unknown address) ? Or she is worried because she sent them using email without encryption? Where did she sent it from ?

comment How to memorise multiple xkcd-style passwords for particular services?
@SteveDL "correct horse battery staple envelope" for email, "rainbow sand pipe nose face" for facebook, "dark bug hole scream gates" for your microsoft account... where the last word isn't random, just associated with the service/site/program...

comment How to memorise multiple xkcd-style passwords for particular services?
@SteveDL ah, thought was a mistake, because of the "service name" phrase that I didn't use. Thanks for your comments: I assumed that the OP said he would use the "correct horse" method to generate N passwords, one for each site, as he said he would "memorize all of them". And that the problem was only to know which password was used at each site/program. So, having a strong password, adding one element to associate it with the site wouldn't decrease the security.
