Introducing a GeekOut Rockstar: Marcus Lagergren


Marcus Lagergren was one of the founding members of Appeal Virtual Machines, the company that developed the JRockit JVM, bought by BEA Systems in 2002. Marcus has been team lead and architect for the JRockit code generators and has been involved in pretty much every other aspect of JVMs over the years. Between 2007 and 2010, Marcus worked for Oracle on fast Virtualization technology. As of September 2011, he is a member of the Oracle Java language team, investigating dynamic languages on the JVM and general runtime futurist. He is the co-author of the book “Oracle JRockit – the definitive guide“, which, despite the product centric title, has been praised as the best book ever written on JVM internals.

We caught up with him recently:

SM: Hey Marcus, good to speak with you! Have you ever been to Estonia/Tallinn before? If yes, What were your memories? If No, what are your expectations?

ML: I have not! It’s a crying shame that it’s just a short ferry ride away and I have many Estonian friends.

SM: What sessions are you giving at GeekOut and what are they about?

ML: I am talking about the JVM vs the OS, when they get in each others’ way and when they help each other. Virtual machine dialectic. It was original proposed by Fredrik Öhrström, now at Spotify, who couldn’t make it last year

SM: What sessions are you looking forward to attend?

ML: All of them! This looks like distilled quality!

SM: What made you select GeekOut as a conference to attend/speak at?

ML: It was in a time window where I thought I wasn’t going to be busy with a Java 8uX death crunch and Anton kind of strong armed me to do it over the course of a year… [ Good work Anton! :) ]

You can catch Marcus’ session on Thursday 12th June at 16:00 – The OS/JVM dialectic – ending the struggle through unity
