Using Macs at WSA (basics)

Materials on creating files and folders on the Mac Operating System (10.5 / Leopard). Creating folders to organise your files is very important, this will help you to keep track of your work, create simple backups (making copies of data so that these additional copies may be used to restore the original after a data loss event.) and much much more. Whatever computer you like using, they all work on the basic principle of using folders to organise files. Files and folder should have meaningful names do not use special Characters like £$%&! and never use a ‘.’ except before a file extension. It is best to start creating your folders in the documents (or my documents) folder and not on your desktop, it gets untidy.

WAIS seminar: The Domain Name System: a magical mystery tour

Wednesday 12th March 2014 Speaker(s): Dr Tim Chown Organiser: Time: 12/03/2014 11:00-11:50 Location: B32/3077 File size: 642 Mb Abstract The WAIS seminar series is designed to be a blend of classic seminars, research discussions, debates and tutorials. The Domain Name System (DNS) is a critical part of the Internet infrastructure. In this talk we begin by explaining the basic model of operation of the DNS, including how domain names are delegated and how a DNS resolver performs a DNS lookup. We then take a tour of DNS-related topics, including caching, poisoning, governance, the increasing misuse of the DNS in DDoS attacks, and the expansion of the DNS namespace to new top level domains and internationalised domain names. We also present the latest work in the IETF on DNS privacy. The talk will be pitched such that no detailed technical knowledge is required. We hope that attendees will gain some familiarity with how the DNS works, some key issues surrounding DNS operation, and how the DNS might touch on various areas of research within WAIS.
