Too basic for this kind of event.
This looked to me more like a sales pitch for the book, than an authentic keynote. Having the "limited-time-promo-thing" on each and every slide was bad taste.
Speaking about the content of the talk: the "problem" has been shown from every possible angulation ("estimates are irrelevant") but what is the real alternative? How do you estimate the cost of a project if you don't do estimates? This as been tacked only in the questions, and was in practice not answered.
Nice presentation (Lego FTW), and great presentation skills of the speaker (very engaging). Some of the presented git commands and options where new to me. Hence, the talk might be targeted at beginners, but it contains things that are of interest to advanced users as well.
The presentation skills of Ben were good, but the talk itself (content) was way too basic and outdated.
Very good talk that I was looking forward to, and I wasn't disappointed. Nikic was able to break down a very complex topic to a level that pretty much everyone is able to understand. The pace was to slow for my taste, but I am certain that it was perfect for the majority, and allowed everyone to follow easily.
Very good talk on a topic that is very important, incl. some funny moments (like developer salaries, which are super high in US but not so much in EU).
Very good talk with an easy to understand explanation of things. There were a few super tiny errors, and I think that it should be made clearer why an AST is so much better than operating on a token stream directly (e.g. revisiting of nodes, attaching extra info, down/up optimizations, etc.).
@Luca Gallinari Thanks for the honest feedback. Yes, it's very much a beginner talk, which isn't necessarily obvious from the name or abstract. This talk was also a shorten down version of a 1 hour talk, and I think some of the more interesting pieces got lost in the process.
A really nice and entertaining talk.
This has been interesting to hear, and well presented. Perhaps a bit basic, but still very relevant to many of us, who maybe are involved in more standard web projects.
