Today we sit down with Erlanger Viktória Fördős, who talks with us about Erlang and how it is used at Cisco. We open the show by finding out about Viki’s background in coding and her unorthodox entry into the field. After hearing about her experiences in her school choir and her transition into the informatics faculty, Viki talks to us about her first experiences in coding and the thrills she found in it. She then expands on the topic, revealing how she approached people to build their websites using her newfound skills in HTML and PHP. A flash-forward later, and Viki shares details about her role as an NSO Core Engineer for Cisco. After hearing how NSO serves as a network operating system, device automation platform, and orchestration engine, Viki explains why NSO is so special. She touches on fast map-based service and some of the ways she and her team implement network-wide transactions using — you guessed it — Erlang. Viki then explains Erlang, how you should approach it if you’re a newbie, and what to expect from its biggest challenges. She elaborates on tail-recursive functions and high-level vulnerabilities concerned with SSL crypto libraries, system integrity, and atom tables. Toward the end of the show, we ask Viki to tell us about her Code BEAM presentation and about her thoughts on why academia and industry should collaborate on a more regular basis. Join us today and be treated to an enriching conversation about Erlang, as well as our secret mini-feature segment!
