[plt-scheme] Re: Poacher turned gamekeeper

Hi Philippos,
Well my name is just Hari:-). I agree with you... I was just trying to share my experience with you thats it... 

Thanks for the links... I will definitely go thru' it...

Thanks
Hari

Hi, Krhari. 
Well, I think that having six in other Schemes won't hurt at all. I mean, if you want, you can stay with traditional Scheme. If somebody wants, s/he can use six-syntax. By the way, you may want to visit a Bigloo web application: 

http://hop.inria.fr/ 

You may also want to see a PHP compiler written in Bigloo (in fact, it generates Scheme, that Bigloo compiles):

I also suggest that you show Maxima to your brother. I am sure he will like it.

Hi, 
I had a interesting experience last week... My brother who is doing his PhD(Mechanical) in UIUC had a presentation to give in his research group meeting... He uses a lot of MatLab... And he was struggling to do some simulation... He discussed it with me and I suggested that I will try it with PLT Scheme. Initially he had lot of doubts about it as he had never heard of Scheme but I insisted and he gave me a small data series and I came up with a simulation and he liked it. Then he asked me if I could implement the actual equations. He had 10-12 of them. I implemented it and gave him the actual code. He was very happy as the animation was exactly as he had imagined. And told me he understood the code very easily... He never asked me any questions. 

In his meeting when he showed the animation to his group, he told me that a couple of other PhD students and a Professor were really very happy with the animation and the simplicity of the code and they wanted to learn PLT and asked him for study material for PLT Scheme. I pointed them to many tutorials that were mentioned in the older posts here... 

I think no one had any FP background there(at least not my brother). And they liked it without Gambit so I don't know they might love Gambit more... But it worked here without Gambit or Bigloo... Just thought of sharing it... 
Thanks 
Hari

I often wonder why all Schemes don't have something like Gambit-C SIX syntax. After all, the the traditional syntax would still be available, if one needs or prefer it. One needs the traditional syntax to do things like genetic programming, neural networks or macros. One may often prefer it. There are people who cannot swallow Lisp prefix syntax. I have shown Lisp, PLT and Bigloo to many people who uses tools like Mathlab. I always succeed in making them accetp Lisp. Here is what I do: 

1 --- If the person needs a lot of math and computer algebra, I compile Maxima on SBCL to make it very fast. In fact, it becomes as fast as Lisp itself. People are amazed at the possibility of doing the same thing that they were doing in Matlab, and using similar syntax. 

2 --- If the person works with network, Internet etc. I try to sell them Scheme. I discovered that it is much easier to sell them Bigloo and Gambit, that have an infix syntax than PLT or Larceny. 

Since providing an infix syntax seems to be very easy, I wonder why this does not become official. As far as infix syntax goes, I have a few complaints to file against the existing ones. 

1 --- SIX requires one to declare types. People with a Matlab background finds it annoying. 

2 --- Maxima adds a lot of annotations to the prefix representation of the infix syntax. I am not sure, but I believe that this may slow processing. 

3 --- Bigloo requires the presence of the bigloorc file at every point where one launches the interpreter. If the programmer forgets the bigloorc file, goodbie infix syntax. 

I am sure that all the above problems can be easily fixed.

I am about to teach this in PLT for the first time. I'll point to lecture notes when I have them. -- Matthias
