Now, he is working for astartup in South Korea, looking for some more interesting stuff to dive in toClaes jakobsson started his career in the mid-90s and quickly became involvedin the open source community, hacking code and organizing stuff in his hometownof Stockholm. Although Perl is his primary focus, he made forays into PostgreSQLCURL and other projects. His daytime occupation has been mostly financial systemsbut at night, playing with embedded systems, microcontrollers, virtual machines,compilers, and the interest du jour kept the mind at bay. He is a technologist atheart with a mind to share and he is always eager to see what happens nextIan Mcalpine was first introduced to computers at his school, to the researchmachine rml-380Z and his physics teacher s compukit UK101. That was followedby a Sinclair ZX81 and then a BBC Micro Model a, which he has to this dayThat interest resulted in an meng in electronic systems engineering from astonUniversity and an msc in Information Technology from the university of liverpoolIan is currently a senior product owner at SAP. The introduction of the raspberry pirekindled his desire to"tinker", but also provided an opportunity to give back to thecommunity.
