 {\bf Cookie Law:}\smallskip\\ ``In May 2011, a
 European Union law was passed stating that websites that leave
 non-essential cookies on visitors' devices have to alert the visitor
 and get acceptance from them. This law applies to both individuals and
 businesses based in the EU regardless of the nationality of their
 website's visitors or the location of their web host. It is not enough
 to simply update a website's terms and conditions or privacy
 policy. The deadline to comply with the new EU cookie law was 26th May
 2012 and failure to do so could mean a fine of up to

 %For instance, SHA512crypt, which is included in Mac OS X and most Unix-based operating systems, passes text through 5,000 iterations, a %hurdle that would have limited Gosney to slightly less than 2,600 guesses per second. The Bcrypt algorithm is even more computationally %expensive, in large part because it subjects text to multiple iterations of the Blowfish cipher that was deliberately modified to increase the %time required to generate a hash. PBKDF2, a function built into Microsoft's .Net software developer framework, offers similar benefits.

+\item Hope it works\ldots\medskip\pause
+\item It is important to use lecture capture wisely:
+\begin{itemize}
+\item Lecture recordings are a study and revision aid.
+\item Statistically, there is a clear and direct link between attendance and
+attainment: Students who do not attend lectures, do less well in exams.
+\end{itemize}
+\item Attending a lecture is more than watching it online -- if you do not
+attend, you miss out!
