Portability is a huge issue that we aren't about to conquer just yet. You can see Sun tearing their hair out over this issue and Java. *But* by using Python, we are in a much better position to port Loci than EMBOSS would be. ***It's a tradeoff guys! We are sticking with one platform for development so that we don't limit ourselves to the intersection of all UNIX, Windows, and Mac GUI, which is relatively small. *And* we get to use native UNIX implementations, not everything running through a virtual machine. Besides, I have confidence that GTK/GNOME will find its way to those other platforms without any effort of our own. If not, we'll see about porting to native Windows and Mac API...It's been done. > Our main concern should be getting it to work under Windows, > since those who use any other Unix won't have any trouble with Linux if > they need to run it.

Yes, that is exactly what the Web interface is targeting :-) But can we put all of the bells and whistles in the Web interface that we have available with GTK? There is just no way right now. As I said in my last e-mail to Carlos, we want Loci to be as dynamic as Word and Excel. If Microsoft can't put those in a Web browser, I certainly doubt we could put Loci. The Web interface will simply have to work with the limitations imposed on that type of interface. > I think this is where Perl really can be useful.

I don't know if there is a GD module for Python. We'll have to look (Konrad, do you know of one?). There is an XML parser being developed by the Python developers. Of course, Python can handle text as well as Perl can. > Oh, the way I envisioned it, the Web interface would be a package that > could be installed on any Loci server as a Loci client and it would use > CGI to handle the requests from other computers. Yes it would be a client in the way it would substitute for all (nearly) of the client side loci. But it would act as a Web server (really, work with a Web server) that can be tapped into by anyone using a Web browser. Where should it go? I think we may just need one at the main Loci URL (which doesn't exist yet). Why do you think it should be portable? It can be, but I don't think it has to be, as long as one Web server can handle the requests. > I think I'll do this project, as I haven't taken any molbio/genetics > courses yet.

But let's see what we can do using standard CGI over JavaScript (see my last message). If we have to use it, then we have to. > (Does IE have layers support?) You've got me there.
