Learning Haskell

With thanks to Jao, a tutorial from this year’s OSCON on Haskell. Haskell has become famous because Pugs, written in Haskell by Audrey Tang as a learning exercise, re-energised the development of Perl 6 by providing an alternative implementation of the Parrot runtime engine.

Have a copy of the slides handy when you watch

Notes from Securecon

Last week I attended SecureCon. Here are a few rough notes:

• At an attendance cost of $0 it was stunning value for money
• Damn Vulnerable Linux is a really useful sample of cracking tools and information for the professional
• Security attacks continue to get worse and there is serious money involved
• Defence in depth (firewalls, OS patches, bandwidth throttles, user education, VLANS to separate traffic types, security zones, policies and policy updating, continues testing, application architecture and design for security,….)
• Assume everything is evil, including traffic from your own network
• Protect the data
• Constant demands for new functions and access mitigate against closed security (e.g. Javascript is about to get access to the local file system)
• New devices (e.g. mobile devices) and new services (in particular VOIP) increase the attack surface, sometimes by an order of magnitude.

A great Christmas present for the cracker in your family
