Lambdas: Myths & Mistakes

This evening I went along to SkillsMatter to watch Richard Warbuton give his talk "Lambdas: Myths and Mistakes"

FEEDBACK

• Always good to have humour in the presentation
• Great to invoke audience participation
• Awesome to have well formatted and properly colour coded code
• Too many "umms" throughout, will be improved with practice.
• Particularly noticeable when demo'ing the conversion to lambdas for the first time.
• Perhaps the jump from external iteration to internal iteration was too fast?
• Speak a little about streams first?
• However it was good to see a worked example straight away
• During some parts of the talk, around myths, there seemed a lack of "relevance"
• Not knowing which section a slide was part of was an issue. ("Is this still related to Myths?")
• Namely when you were talking about "Differences between expectations"
• You mentioned "Boxed primitive error messages" for streams(?). Would be better to show people rather than just telling them.
• Throughout the slides kept being changed accidentally, be wary of this as it can be jarring.
• When showing a visual example, try to keep the following code example the same.
• Don't add 1 to 4 visually and then suddenly count numbers in code.
• You mentioned "simply using .forEach() isn't great", perhaps show a quick example of "a better method".
• Going through the "count all occurrences in a book" kata. Don't just show the code solution, first talk through the semantics in plain English!
• Similarly going backwards and forwards across the messed up half solution isn't so valuable.
• Overall the content was fantastic and pitched at a good level.

FEELINGS

• This talk has left me really hungry to start using Streams and Collectors in anger.
• Visualising all these abstract concepts really seems like the way to go!
