Who am I?

3

  • I am a Physicist;
  • Until last year I was investigating

neutrino oscillations for the ANTARES/KM3NeT Collaborations;

  • I had never heard about OSGi or

Eclipse before.

Which were my “versatile” skills?

4

  • Programming skills (mostly C++);
  • Statistics and data analysis;
  • Problem solving approach.

Why am I here today?

  • I am not here to teach you anything;
  • I want to share my first impressions on

the OSGi technology and Eclipse framework as an “outsider”;

  • Give a feedback after my first year

working with these technologies.

Modeling is a real mind exercise

  • It forces you to deeply

understand the problem you are facing;

Modeling is a real mind exercise

  • It forces you to deeply understand the

problem you are facing;

  • You have to get how things

are related to each other if you want to build a solid model;

Modeling is a real mind exercise

  • It forces you to deeply understand the

problem you are facing;

  • You have to get how things are related

to each other if you want to build a solid model;

  • It teaches you how to

recognize similar structures and generalize concepts;

  • You have to get how things are related

to each other if you want to build a solid model;

  • It teaches you how to generalize

concepts;

  • It is not so different from the

work of a physicist, if you think about it...

The hardest parts...

  • Get familiar with all the

terminology and the domain

  • f the different features (still

work in progress);
