Sorry, that message wasn't meant for the whole list... But given that you ask, picobit is a Scheme compiler for a very compact VM that I wrote a few years ago for embedded applications. Here's the paper Vicent St-Amour and I published at IFL09 (it won the "best paper award"): http://www.iro.umontreal.ca/~feeley/papers/StAmourFeeleyIFL09.pdf Marc

Picobit is available on GitHub: https://github.com/stamourv/picobit The latest version includes an ARM port, thanks to Peter Zotov. Vincent At Thu, 19 Jan 2012 18:54:50 -0500, Marc Feeley wrote:

Thanks, Vincent/Marc. Would this facilitate building apps for the Android platform?

Oh my god! I see that you have converted all of the picobit Scheme compiler source code into Racket, which means that picobit can't run on any other Scheme system. When I wrote picobit I was careful to avoid making it Gambit specific so that others could choose to run it on the Scheme system of their choice. As far as I can tell the original picobit compiler ran fine under mzscheme. Now that you have converted it to Racket, it has been swallowed into the Racket ecosystem to the exclusion of others, including me. This is really ***NOT COOL*** from an engineering point of view. This is really ***NOT COOL*** from a political point of view (dividing the Scheme community). This is really ***NOT COOL*** because you did this without consulting me. This is really ***NOT COOL*** because it makes it hard for me to contribute to the project. Can you please explain what was the motivation for doing this? Wouldn't it have been sufficient to add a #lang r5rs at the top of the files to make it work with Racket without breaking compatibility with the other Scheme systems? Marc
If you prefer that I stop working on Picobit in Racket, I will stop. If you want, I can remove the code from GitHub. Sorry for any misunderstandings. Vincent At Fri, 20 Jan 2012 09:52:02 -0500, Marc Feeley wrote:

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Apologies for butting in, but maybe my stating some obviousnesses can rerail your conversation. Vincent, it seems clear that Marc really wanted picobit (derivatives) to remain cross-scheme and got a nasty surprise when he found he had been thwarted in this. Probably racket provided some convenience to you or is more familiar to you, so you chose to work in that. Maybe you weren't ware of the cross-scheme nature of picobit. Maybe you could explain your choice of using racket and list any racket features that simplified picobit code so that an estimate could be made of the effort of porting back to a (more) cross-scheme state. Marijn PS I think a big part of the current situation is that there is very little effort put into reducing gratuitous incompatibilities between schemes. Hash tables come to mind. It would be nice if such incompatibilities could be brought up on comp.lang.scheme or cross-posted between affected implementations or discussed on scheme-reports or something such that we can start reducing gratuitous incompatibilities and move on more fundamental differences from there. Really it makes no sense to me that the only inter-implementation communication seems to be when a new report is in the works. On 20-01-12 20:13, Vincent St-Amour wrote:
