Question: My bank (President's Choice Financial in Canada) is offering Rapport by Trusteer, do you know anything about it and do I need to use it? Also can you create your own operating system called; SOS (Steve's Operating System)
Answer: Steve will be creating his own operating system for the PDP 8 but doesn't have enough time to write one for modern computers. The software he is talking about hardens the web browser by doing things such as enabling private browsing and preventing DNS spoofing. Steve recommends using it. It is being offered as the bank has no control over its users computers and so they try to protect the user if they have malware on their computer.

Question: [ 05 ]
52:51 - 58:22 John (Baltimore, Maryland) [Read after question 6 as Leo missed it]
Question: Is a 1024 bit SSL certificate key secure or is it time to move to 2048 bit like the root certificate authorities use ?
Answer: The 1024 bit key that are issued will expire within a couple of years meaning that they can safely be 1024 bits. Root certificate authorities have longer expiration dates on their keys so they need to be longer incase something happens in the future before they are renewed.
Comment: [ 06 ]
47:55 - 52:50 Lex Thomas (Research Triangle Park, North Carolina)
Listener Comment: A maxim they like is "The activity of debugging, or removing bugs from a program ends when people get tired of doing it, not when the bugs are removed." Datamation, January 15, 1984. For those who are waiting for Microsoft to quit having Patch Tuesday, I'd say they are waiting for Godot"

Comment: [ 07 ]
58:23 - 01:01:36 Tim Lemmon (Atlanta, Georgia)
Listener Comment: I tried to use my knuckle at the Disney theme park entrance instead of my fingerprint and it didn't work. This may be because they still have my fingerprint on record from 3 years ago or the system is smart enough to recognise it wasn't a finger on the reader
Steve's Comment: Your fingerprint is probably being stored on a insecure database somewhere and Steve recommends using an alternative finger to what they recommend.
