  Dear Chris Mcdonald,
  
  Hope you are well. My name is <name removed by request> and I graduated from
  UWA with a Honours degree in Mathematics, second major Computer Science.
  I am now a software engineer, and as part of ongoing professional and
  personal development, I like to review what I have learnt in the past.
  I wish to email you today to express gratitude for keeping the course
  materials available each year on the csse website, but also to commend
  you for your exceptional presentation and deliverance of CITS2002.

  I will confess, when I first took the unit in 2018, it was daunting and
  a big step up in difficulty from what I had experienced before. However,
  it was absolutely indispensable for my development and the experience pays
  off everyday in my working life. The project in my year was Bakefile; At
  the time, I had doubts if I could do it, but due to the course materials
  being organized so well and lectures interesting, I did. The 'can-do'
  attitude you have in the lectures and patience for student's questions
  ranks the highest of any lecturer or professor I had during my time
  at UWA.
  
  Reviewing the materials now, not only is it informative and easy to
  follow, it is also extremely enjoyable. In particular, the hash table and
  list data structures are implemented in an easy to understand way and are
  effective. Also, its very nice to see the threading topics, which I do
  not remember doing during my year. The projects are interesting, useful
  (employers may pay attention to these!) and are a great way to introduce a
  student to the world of complex systems. After all, if a twenty something
  can develop a halfway functioning Makefile program, what else can they do?
  
  In summary, I thank you for your hard work. I thank you for presenting
  what some may consider dry material in a accessible and extremely
  interesting way, and I thank you for your dedication and time. I hope
  that you read this email and feel that your efforts are appreciated,
  at least from one student.
  
  Sincerely,
