Great introduction to varnish, already sent you additional feedback by mail

Nice, interesting talk. Flysystem looks pretty useful, might have a play around with it soon :)

An excellent and very insightful keynote, I thoroughly enjoyed it.

Much of the facts were presented with a lack of context. You showed different ways to define a function, but didn't explain why you would (or shouldn't) use them.

Same goes for the immediate functions and the private properties constructor: you didn't mention the downsides and upsides of those patterns, ie. the fact that defining your object methods inside the function is a killer for memory usage as they are being defined for each instance of the object...

Why didn't you say anything about prototype based programming, probably the most fundamental difference with many other programming languages ? I believe this knowledge is much more important then knowing what the "real" definition of a closure is...

Your answer to the debug question (admitting you're not really a JS developer and you simply console.log your way through) pretty much confirmed you have much to learn about Javascript.

I recommend reading these books:

Insightful and thought provoking ideas! Really enjoyed it

Interesting talk, good presentation skills, some very funny opinionated slides. Good clear explanation of what's happening under the hood

An interesting talk; and while it didn't really show any benefit of using lists implemented in pure PHP over using SPL's built-in lists, Toon's enthusiasm for and love of playing around with datastructures really shone through in his talk
