[Lift] Re: Feedback on screen cast, please
David, Your screencast is very well done. There is one small change i would make to add a layer regarding the management of complexity. Make a change to the app: a small but noticeable change, like reorder the messages newest to oldest with a timestamp, or something. It would be ideal if somewhere in your modification you commit an error that is subsequently caught by typing. These two basic points dovetail nicely into a crucial point that Bill Venner's makes in his JavaOne presentation: types don't prove your program correct; types prove changes to your program correct. i think you could increase the bang-for-buck by a factor of 2 while only adding 15 - 20 secs to the time.

Great stuff! The only thing I can think of that could be improved is maybe mentioning the JavaRebel stuff; when seeing Rails demos, there's no stop-start-wait-30 seconds type stuff while maven does its thing - maybe in the next screen cast the JavaRebel stuff could be shown so that the same rails-ish RADness is possible. 2009/4/25 David Pollak : > I've posted it at blip.tv: > > http://liftweb.blip.tv > > It seems to have good audio synchronization. > > On Sat, Apr 25, 2009 at 6:04 AM, Derek Chen-Becker > wrote: >> >> Hmmm.

Very nice. I don't think it matters whether it's AVI or Flash, but it would definitely help to pick a good codec for screencasts so that it's not a 200MB file. You might even want to look at Wink: http://www.debugmode.com/wink/ It does isolated screenshots, but in many cases that's clearer than a lossy video codec.

[Lift] Re: Feedback on screen cast, please
The fact it's real-time is excellent. It's the right amount of info/code to whet someone's appetite to dive into Lift a bit more. And since the amount of code is small, someone would be able to follow along easily. The areas of improvement would be upping to production levels a bit. The PeepCode screencasts are what come to mind as a standard to aspire to. Nice stuff. I've been knocking the idea around with Derek and Marius for screencasts. I think it's a logical extension of the book.
