[Buildroot] "Buildroot: what's new" slides

[Thomas Petazzoni]

Hello,

On Tuesday this week, I gave a talk "Buildroot: what's new?" at the
Embedded Linux Conference Europe in Prague. I have published the slides
online at
http://free-electrons.com/pub/conferences/2017/elce/petazzoni-buildroot-whats-new/petazzoni-buildroot-whats-new.pdf.

The room was rather full, I believe perhaps 60-80 people in the
audience, but the projectors were so bright that I couldn't really see,
so perhaps Arnout, Peter or Yann who were in the audience can give
more details.

The talk included a poll. I think about 90% of the room already knew
about Buildroot, and a good 60-70% of the room was already using
Buildroot. Perhaps 30-40% of the room was using OE/Yocto, and less than
10% was using OpenWRT. Note that this is of course not representative
of the build system "market share" since people showing up at a
Buildroot talk are likely to already be interested in this build system
more than in others.

This time around, my talk nicely fit within the time slot, so there has
been some time for questions. The ones that I remember:

 - Is there some support for the Rust language. I mentioned the patches
   from Eric Le Bihan, and said help was definitely welcome.

 - A person asked about syslinux support on the target: we currently
   build syslinux itself for the target, but the tools are built for
   the host, but there are scenarios where the tools are needed on the
   target as well. I had the chance to discuss after the talk with this
   person from Airbus, and I explained how it should probably be done
   (host-syslinux installing the host tools, target syslinux installing
   syslinux itself with an option for the target tools)

 - A person asked how to use Buildroot during application development,
   so I gave some more details about <pkg>_OVERRIDE_SRCDIR and how it's
   intended to work.

Perhaps Arnout, Peter or Yann will remember other questions.

All in all, I think it was a good experience, large audience,
interesting questions and feedback. It is worth mentioning that Yann
gave a Buildroot related talk right after mine, I'm sure he will be
publishing his slides very soon.

Best regards,

Thomas

Well, the room was 100% full, and I counted ~25 rows of ~15 chairs. So
your maths are totally off by a factor of ~5. ;-)

The /other/ Yann E. MORIN already uploaded his slides to the official
ELC-E website:
    http://events.linuxfoundation.org/sites/events/files/slides/2017-10-24%20-%20ELCE-Buildroot.pdf

And the video is also on-line (but be prepared for an awfull prestation
on-stage):

Woh, already online! That's fast!

25 by 15 is 375 persons. I clearly don't think this room had a capacity
of 375 persons.

Your presentation was definitely interesting. It goes in-depth into
how to customize Buildroot for advanced use-cases. It is clearly not
for beginners, but it shows how Buildroot can be used in very advanced
situations.

Best regards,

Thomas

Well, the left alley had 4 seats, and the right one was more than twice
as wide, so at least 10 seats; that's 14. And I did count the number of
rows, and IIRC it was 25. Maybe I'm off by 1 or 2, so let's say 23.
That's still 322.

Yes, that room was bigger than you remember. ;-)

Yann E. MORIN.

Regarding to this patch series, I did not sent a new version featuring
latest Rust version (1.21.0), as there were some points to be cleared
[1]:

- should the standard library be available as a separate package?
- how can the package providing the compiler as binary be used to
  bootstrap the compiler built from source (in terms of Buildroot
  package declaration)?
- method for crate (Rust package) retrieval (i.e. package management).

Comments and suggestions welcome.

Thank you both for sharing the talks. It's nice to put some faces to the
names here :-).
