Dutch PHP Conference 2017
29 Jun - 1 Jul 2017 at RAI Amsterdam

I think the hammering down of 'rule 1' is a good indication of the level of experience of the speaker with the subject matter; which is to say that it's not very high. The mention of PSRs gave me hope that this would be an informative in-depth talk about caching.

I honestly liked the history lesson, I think that was a good idea. The technical coverage of caching however seemed to be based a little too much on the PSRs. The PSRs cover just the interface and the interface of a caching system is quite simple. Caching as a technical tool however is very hard. Beyond stampeding no real technical challenges were covered and the coverage of stampeding could have used a little more explanation. The slide with the moving timeline .. that's a bad slide. I think it would be a good idea to have a slide that shows a timeline where stampeding happens and then a slide where stampede is averted. Also there was no code sample that shows stampede avoidance.

Presentation style could also use a little more work. The hammering of rule 1 becomes extra annoying if you're stumbling over the words.

Maybe if this talk was 20 minutes, it would be ok but for 45 minutes there just isn't enough information.

Had fun, of course my first try to commit this comment ended up like this:

An Error Was Encountered
Request was invalid. Tokens did not match.

Take my internet points for a job well done :)

Every conference needs a talk like this, very inspirational.

The best talk of this covfefe. It's true.

I liked the talk. I like the anecdotes and the fairly concrete set of rules that explain why you decided to use XP. I think I understand them well enough to bring them into practice myself.

Good start, good finish but the middle bit where you dive into the matter of the book was a little dry. I think you can leave that out entirely without diminishing the integrity of the talk.

Maybe you could pivot the talk a little bit towards using XP to solve specific issues. Personally I don't see XP as something that you should do always all the time; and since most people are not doing XP focusing on strong reasons to start dabbling with XP might be a good way to frame the talk.

Cool
