Virtual Machines: Joa Ebert (@joa)
I have been following Joa Ebert’s work for quite some time now, and I am very happy to see that he had another session at FITC Amsterdam 2013. There are a couple of speakers that always know how to pack the room: Grant Skinner, Lee Brimelow and Colin Moock just to name just a few - Joa Ebert is also one of them. I tried to get into this session a little early just to get a seat.
My hunch was correct. The room was packed with people, 99% developers and 1% FITC staff. We were all getting ready for what would probably be the only 'hardcore' technical session this year at FITC. The topics that Joa covered were: “What are Virtual Machines?”, “Why do we need Virtual Machines?”, “How do Virtual Machines work?” and “Where are the issues?”
He started off his session seeming a little nervous, showing images of cakes. Really complex cakes. With ribbons, extravagant decorations and loads of color. Joa is a foodie! I was loving the session already, and found myself hooked from that point on. He explained that cooking and programming have a lot of overlap. Cooking requires precision and so does coding. However, when we look at coding, we must first consider what makes our programs run. A virtual machine.
In order to know what a virtual machine is, we must first look at what a real machine is. Basically, a virtual machine (or VM) is a simulation of a real machine. With programming, we use process vm’s, that start and stop with the beginning and ending of a program. A VM is used for code execution, and it handles memory management and multithreading.
This was one of the best sessions I have attended in the last while. I think I learned more about VM’s and garbage collection in one hour of hearing Joa speak, than I did in 4 years of college.
