[Haskell-cafe] Haskell showcase in 5 minutes - follow-up

2012-03-01 Thread Arnaud Bailly
Hello Cafe, Thanks to all of you who provided ideas and suggestions for introducing Haskell. I finally went the simple way, presenting the "knapsack" problem slightly reframed using tapas (spanish dishes). This problem is small enough to fit in the 5 minutes time-frame and it actually illustrates s

Great ! Good to have some support. Hope you will like it, I think I got something worthwhile that fits in 5 minutes flat. On Wed, Feb 29, 2012 at 10:46 AM, Yves Parès wrote: > Yes, but in 5 minutes I take it they won't have time to ask questions > before your presentation is over. > > I haven't

Yes, but in 5 minutes I take it they won't have time to ask questions before your presentation is over. I haven't thought about parallel computing but it's one of the many assets of the language. The problem IMHO with STM is that it relies on too many Haskell elements to be grasped in 5 minutes. M

Thanks for your support. I would really like to do this but 1) the talk is tomorrow evening and 2) I do not have time in the interval to learn yesod and/or gloss enough to be confident that I will not botch anything in a 5 minutes time frame. I did recently a 2-hours long talk with same purpose (i

Here's an example that fits comfortably in 5 minutes--if your audience knows elementary calculus: http://www.cs.dartmouth.edu/~doug/powswer.html It depends critically on lazy evaluation, which knocks out a lot of competing languages right from the start. The five-minute version would begin with po

Thanks Yves for your advice. And I agree with you that too much laziness may be mind-blowing for most of the audience, yet this is one of the characteristics of Haskell, whether or not we like it and whatever troubles it can induce. I really think the knapsack is simple, not too far away from real

Where exactly does that event take place? Is it open to public? And I strongly disadvise fibonacci, quicksort and other mind-blowing reality-escapist stuff. Show something real world and practical. 2012/2/27 Arnaud Bailly > Hello Cafe, > > I will be (re)presenting Haskell in a "Batlle Language"

Well, solving knapsack problem in a couple lines of code looks really fun and instructive. Thanks Ertugrul for suggesting Yesod. This is definitely a great tool for creating web applications but I fear that's too much to swallow in 5 minutes. And thanks also Jason for reminding me of the gems one
