The main idea of the Pharo User Association is to collect funds to support the development of Pharo itself. We are paying costs of infrastructure as well as, in collaboration with the Pharo Consortium, development capacity for Pharo itself. As such, all members benefit from every other member's contribution.
In addition, as a member you get:
Discount to attend Pharo Days. The last years it was EUR 89 instead of EUR 199
Lam Research, a leading supplier of wafer fabrication equipment and services to the global semiconductor industry, is an experienced user of the Smalltalk programming language. Smalltalk is a key component in Lam's software control system for a broad range of the equipment it manufactures. Tudor Girba is a leading member of the tools and environment development effort in Pharo, having architected the Glamorous Toolkit for live programming. Eliot Miranda is author of the Cog virtual machine that underlies Pharo and other Smalltalk dialects.
Lam has engaged Tudor and Eliot to explore potential enhancements in Lam's use of Smalltalk. These enhancements range from running highly optimized Smalltalk on low cost, single board computers, to enhancing Lam's Smalltalk development practices with state-of-the-art live programming. During the engagement, Tudor and Eliot successfully moved a key communication component of the control system to Pharo. It was a challenging task aimed at extending the reach of Lam’s system to the Pharo world including the option of executing on ARM processors. http://pharo.org/success/LAMRC
