Electronic copies of these documents
(cid:73) Electronic copies of your particular version of the materials are
available on:
http://free-electrons.com/doc/training/linux-kernel
(cid:73) Open the corresponding documents and use them throughout
the course to look for explanations given earlier by the
instructor.
(cid:73) You will need these electronic versions because we neither
print any index nor any table of contents (quite high
environmental cost for little added value)
(cid:73) For future reference, see the first slide to see where document
updates will be available.

Free Electrons: not a training company
Free Electrons is an engineering company, not a training company
(cid:73) Training is just one of our activities
(cid:73) Whether they are directly employed by Free Electrons, or
whether they are external developers that we know very well,
all our trainers are engineers first, with extensive on-the-job
experience.
(cid:73) Free Electrons engineers spend most of their time on technical
projects, and share this experience through training sessions
and by keeping our training materials up to date.
(cid:73) All our trainers also spend a lot of time contributing to the
user and developer community, by contributing to projects
(such as the Linux kernel, Buildroot and Barebox), and/or by
sharing technical information (through blog posts, training
materials and talks at international conferences)

Free Electrons: what’s special
(cid:73) Engineers recruited in the heart of the embedded Linux
developer community.
(cid:73) We are very familiar with the best solutions the community
offers to product developers.
(cid:73) Contributing as much as possible to the community: code,
documentation, knowledge sharing, financial support.
(cid:73) Our engineers regularly go to the top technical conferences.
We know other developers very well.
(cid:73) Nothing proprietary in Free Electrons. Everything we produce
for our company is shared and transparent (in particular
training materials and even evaluations from all our training
sessions!).
