Pieter Hintjens, of Brussels, Belgium, is the latest visiting hacker to spend some time at Dallas Makerspace. Pieter has stopped by for some of our regular weekly meetings and also gave a talk at our Software Freedom Day event back in September. In addition to being involved with the local hackerspace in Brussels, Pieter is also a well-known opponent of software patents. He defines a patent as “A medieval economic tool by which politicians attempt to stimulate trade and wealth by banning innovation and competition in crucial areas of technology” He’s also a free software developer known for his work on the Advanced Message Queuing Protocol (AMQP) and the ZeroMQ intelligent transport layer. Pieter is also a drummer and we hope to talk him into giving a drumming demo next time he passes through Dallas.
