The “video” (basically audio plus slides) and the slide deck for this talk are available:
If you attended the talk and have feedback, I’d love to hear it in the comments.
I have to admit to having some concerns about this talk. Brian Goetz had two lambda talks (The Road to Lambda and Lambda: A Peek Under The Hood) which cover the territory pretty well. However, Brian is a veritable fire hose of information, and he covered a lot of material — perhaps too much — in two short hours. In contrast, in this talk, I covered perhaps a tenth of the territory in one hour. (I guess that makes me a sippy straw instead of a fire hose.) During the Road to Lambda talk, Brian put up a slide that pretty much covered the material here. I thought, “Well, he just stole my entire talk in one slide.” Then I heard the guy behind me mutter, “This stuff makes my brain hurt.” So maybe there’s room for a different, and more methodical treatment of the material. If this worked or didn’t work, please let me know!

Hi Mark, my name is Emilio Mata, from Uruguay. I could attend JavaOne last year but not this one (I don’t know if I will attend any in the future, its a long way home), but fortunately I could see the video of the talk through the JavaOne links. I am an intermediate level programmer and trying to improve (mostly SE, some EE) and I have been hearing about lamdas for some time, but this is the best material I have seen about it. Excellent for understanting what it is about. Thank you very much, regards.
Hi Emilio, I’m glad to hear that you found the talk useful, even though you didn’t attend the conference. Although I spoke at the conference and attended several sessions, I found the videos helpful too, both to review the sessions I did attend and to watch the sessions that I had missed.
