I'm in Minneapolis, MN today and part of tomorrow, visiting Cargill - a large customer of the Cincom Smalltalk group. They've spent the last decade+ building a large suite of applications they call LYNX - to summarize a lot, it's a system that deals with the grain origination business, through the supply chain from the farmer to the end purchaser. I can't go into a lot of details - like Cincom, Cargill is privately held, and they have a lot of proprietary value locked up in this system. They've evaluated it against various COTS systems over the years, and have always made the determination that LYNX served their needs better.

We got a lot of background on the business and application architecture from them. The application work started around 1992, when they decided to get rid of the various legacy stovepipe systems they had. Later on, Y2K compliance came into play. Just from a Smalltalk perspective, they have an interesting architecture - they have a multi-tier system with VSE clients and VW servers. The VSE clients use CORBA to communicate with VW.

That actually gets into something that not a lot of people know about - there's a VSE CORBA client (not suitable for running servers - it's incomplete) that shipped way back in the day. Cargill has been cheerfully using that code for years. They also wrote their own VSE/VW code compatibility layer - the entirety of their domain model is portable between VSE and VW. The GUI stuff, obviously, is not portable - and they are very interested in Pollock development and our roadmap.

Like I said above, I can't go into many details on the applications themselves - but I can say that Cargill is very happy with Cincom Smalltalk, and is looking to hook the LYNX system up to other systems that are being developed and deployed throughout Cargill. They are getting ready to kick off a fairly large effort soon, and that's what this meeting was all about. The last time they scheduled a large effort (back in 2000/2001), we came in and had extensive conversations with them. Those conversations bore fruit in the work they deployed out in 2003, which saved them a ton of money and streamlined their operations.

It's always fun to talk to a customer doing cool things with the product!
