WEBVTT

99:59:59.999 --> 99:59:59.999
Right, good afternoon

99:59:59.999 --> 99:59:59.999
It is the lightning talks sessions at
DebConf Hamburg 2018

99:59:59.999 --> 99:59:59.999
We've got seven speakers, and I guess
we'll just get going

99:59:59.999 --> 99:59:59.999
Starting with Tobias Platn???,
talking about Debian on Power9.

99:59:59.999 --> 99:59:59.999
Yesterday I, hm no, on friday,
I received my new Power9 machine.

99:59:59.999 --> 99:59:59.999
A Talos 9 (II).

99:59:59.999 --> 99:59:59.999
And it has an IBM Power9 processor

99:59:59.999 --> 99:59:59.999
So, the only distro that I know that will
work is Debian.

99:59:59.999 --> 99:59:59.999
Then, this is a new PowerPC 64 bits
architecture,

99:59:59.999 --> 99:59:59.999
that can run in little-endian mode.

99:59:59.999 --> 99:59:59.999
I downloaded a Debian installer.

99:59:59.999 --> 99:59:59.999
First, I chosed the stable version, but

99:59:59.999 --> 99:59:59.999
that crashed during install.

99:59:59.999 --> 99:59:59.999
And, then I retried a different version,
a daily version.

99:59:59.999 --> 99:59:59.999
And this one, which is based on Buster,
correctly installed.

99:59:59.999 --> 99:59:59.999
I can even have a graphical environment,
working out of the box.

99:59:59.999 --> 99:59:59.999
And, the installer then complained that
there is no boot partition

99:59:59.999 --> 99:59:59.999
for older PowerPCs, and this boot partition is
not needed, since the TalosII

99:59:59.999 --> 99:59:59.999
has a newer systems starting with power7
used petitboot.

99:59:59.999 --> 99:59:59.999
So, that needs to be fixed in the Debian
installer,

99:59:59.999 --> 99:59:59.999
that it doesn't produce the warning
on Power machines.

99:59:59.999 --> 99:59:59.999
And now I have a working Debian
installation,

99:59:59.999 --> 99:59:59.999
which I can use.

99:59:59.999 --> 99:59:59.999
(thanks) [applause]

99:59:59.999 --> 99:59:59.999
Thank you very much, that was very quick.

99:59:59.999 --> 99:59:59.999
Next up is Thimothée Jaussoin,

99:59:59.999 --> 99:59:59.999
talking about Movim, the XMPP social
platform.

99:59:59.999 --> 99:59:59.999
Give him a moment to get set up.

99:59:59.999 --> 99:59:59.999
I think it's a bit better this way.

99:59:59.999 --> 99:59:59.999
Who already heard about the platform Movim?

99:59:59.999 --> 99:59:59.999
OK, so we have a couple of people that
know about the project here.

99:59:59.999 --> 99:59:59.999
Just to present you what I ??? could be a
parallel universe

99:59:59.999 --> 99:59:59.999
but is actually the current universe we're
living with.

99:59:59.999 --> 99:59:59.999
Lots of different chat platofrms.

99:59:59.999 --> 99:59:59.999
The same thing on social networks.

99:59:59.999 --> 99:59:59.999
We keep reinventing the wheel
all the time.

99:59:59.999 --> 99:59:59.999
We don't have this problem with e-mails

99:59:59.999 --> 99:59:59.999
hopefully actually the e-mail standards
came way before before all of those

99:59:59.999 --> 99:59:59.999
proprietary solutions

99:59:59.999 --> 99:59:59.999
So we have ??? and Google and Microsoft
are still using SMTP, IMAP, for now.

99:59:59.999 --> 99:59:59.999
So everything is compatible, and we have
a lot of clients on top of that.

99:59:59.999 --> 99:59:59.999
But for chat, and social networks, it's
not the case.

99:59:59.999 --> 99:59:59.999
So the idea of Movim is to build a
social platform.

99:59:59.999 --> 99:59:59.999
In there, we can put a little couple of
ingredients.

99:59:59.999 --> 99:59:59.999
First, it needs to be Open-Source, for the
transparency, for the fact that you can

99:59:59.999 --> 99:59:59.999
have feedback and improvements,
for the security part.

99:59:59.999 --> 99:59:59.999
I think that you guys here know about the
advantages of Free Software, and

99:59:59.999 --> 99:59:59.999
especially on the communication part,
on social networks, but it's not enough.

99:59:59.999 --> 99:59:59.999
We also need to be in control, actually
in this social network.

99:59:59.999 --> 99:59:59.999
So it need to be simple and transparent

99:59:59.999 --> 99:59:59.999
on the UI but also on the protocol level.

99:59:59.999 --> 99:59:59.999
On the really deep below stacks.

99:59:59.999 --> 99:59:59.999
So we'll need to have a strong and reliable
encryption,

99:59:59.999 --> 99:59:59.999
so don't reinvent also an encryption
- talking about Telegram, here -

99:59:59.999 --> 99:59:59.999
And, yeah, need some trusts in sights
here.

99:59:59.999 --> 99:59:59.999
I mean a community, and not a company
that you will blindly trust

99:59:59.999 --> 99:59:59.999
to take care of all of your communications.

99:59:59.999 --> 99:59:59.999
But it's not enough.

99:59:59.999 --> 99:59:59.999
It needs to be decentralized. Because
centralized social networks,

99:59:59.999 --> 99:59:59.999
even if it's opensource,

99:59:59.999 --> 99:59:59.999
if it's only one instance, you have to
still trust the instance. So would like to

99:59:59.999 --> 99:59:59.999
deploy your instance, you would like to
trust someone else,

99:59:59.999 --> 99:59:59.999
you can only, sometimes, trust only
yourself in seldom cases

99:59:59.999 --> 99:59:59.999
Decentralization also brings robustness

99:59:59.999 --> 99:59:59.999
So that's too many times that actually
one server is failing, think Signal

99:59:59.999 --> 99:59:59.999
had an issue recently, about this kind
of thing there.

99:59:59.999 --> 99:59:59.999
The issue was with the Amazon servers,
the whole thing didn't worked

99:59:59.999 --> 99:59:59.999
for a couple of hours.

99:59:59.999 --> 99:59:59.999
And then, resist against censorship and
control.

99:59:59.999 --> 99:59:59.999
Same thing with Telegram, I think in
Russia.

99:59:59.999 --> 99:59:59.999
I'm talking more about the IM part, but
it's also applicable to social networks.

99:59:59.999 --> 99:59:59.999
It's exactly the same thing, just that the
exchanges of information are a bit different.

99:59:59.999 --> 99:59:59.999
So, you need these steps but

99:59:59.999 --> 99:59:59.999
all those platforms here

99:59:59.999 --> 99:59:59.999
(I just made this conference 3 years 
ago, just added Mastodon recently)

99:59:59.999 --> 99:59:59.999
So i might talk about different sorts
of platforms

99:59:59.999 --> 99:59:59.999
There is communication between those
platforms, kind of standards that are

99:59:59.999 --> 99:59:59.999
starting to come in, especially between
Diaspora and Mastodon,

99:59:59.999 --> 99:59:59.999
but there is still a lot of work to do
there.

99:59:59.999 --> 99:59:59.999
So, the secret ingredient is about
compatibility, about extensibility.

99:59:59.999 --> 99:59:59.999
Don't try to reinvent the wheel again,

99:59:59.999 --> 99:59:59.999
don't try to create another social network,

99:59:59.999 --> 99:59:59.999
or another IM platform that will have all
those communication troubles.

99:59:59.999 --> 99:59:59.999
So, I mean a long-term vision.

99:59:59.999 --> 99:59:59.999
And, actually, the secret ingredient
is standardization, in these things.

99:59:59.999 --> 99:59:59.999
So, this standard should
have a couple of features,

99:59:59.999 --> 99:59:59.999
support news feeds, communities, IM, chatroom
presences, know who's online, profiles,

99:59:59.999 --> 99:59:59.999
video conferencing security, bridges to the Web.

99:59:59.999 --> 99:59:59.999
And then it will be real-time.

99:59:59.999 --> 99:59:59.999
And, 1 minute?

99:59:59.999 --> 99:59:59.999
This protocol actually exists, it's called
XMPP.

99:59:59.999 --> 99:59:59.999
So the goal of the project is:
- take XMPP implemented

99:59:59.999 --> 99:59:59.999
- and doing a lot of innovation on
top of the project

99:59:59.999 --> 99:59:59.999
So, server-side it's a simple XMPP
client, webserver, simple to install

99:59:59.999 --> 99:59:59.999
(PHP, MySQL PostgreSQL)

99:59:59.999 --> 99:59:59.999
And user-side, it's also super simple
to use, you need simply a browser,

99:59:59.999 --> 99:59:59.999
it's responsive, it's light, it's fast and
is built actually for small communities.

99:59:59.999 --> 99:59:59.999
There are pods all around the world.

99:59:59.999 --> 99:59:59.999
You're really invited to deploy your own
pods.

99:59:59.999 --> 99:59:59.999
There is already ten thousands accounts
on the official pod

99:59:59.999 --> 99:59:59.999
30 languages

99:59:59.999 --> 99:59:59.999
Debian packages coming soon

99:59:59.999 --> 99:59:59.999
Thanks to the help of some people
in this room.

99:59:59.999 --> 99:59:59.999
And, that's it !

99:59:59.999 --> 99:59:59.999
So if you want more information,
everything is on the website,

99:59:59.999 --> 99:59:59.999
you can join the chat room.

99:59:59.999 --> 99:59:59.999
Or, the twitter.

99:59:59.999 --> 99:59:59.999
[applause]

99:59:59.999 --> 99:59:59.999
Thank you very much.

99:59:59.999 --> 99:59:59.999
Next up is Thomas Lange, Mrfai,
talking about dracut.

99:59:59.999 --> 99:59:59.999
Today, I'm not talking about FAI
but about dracut.

99:59:59.999 --> 99:59:59.999
dracut is a replacement for initramfs
which is used by most other distributions.

99:59:59.999 --> 99:59:59.999
If I'm correct, only Ubuntu and Debian
and derivatives are using initramfs-tools

99:59:59.999 --> 99:59:59.999
All other distributions already moved
to dracut.

99:59:59.999 --> 99:59:59.999
Today I want to show how you can get
an experience with dracut

99:59:59.999 --> 99:59:59.999
without deinstalling initramfs-tools.

99:59:59.999 --> 99:59:59.999
Ben Hutchings did some patches, I think
two years ago, so it's possible.

99:59:59.999 --> 99:59:59.999
What you have to do, there's a package
called "dracut-core",

99:59:59.999 --> 99:59:59.999
which does not conflict with
initramfs-tools.

99:59:59.999 --> 99:59:59.999
I have a virtual machine.

99:59:59.999 --> 99:59:59.999
So, debian/fai…

99:59:59.999 --> 99:59:59.999
On this machine, I will now install
the dracut-core package

99:59:59.999 --> 99:59:59.999
and that's it.

99:59:59.999 --> 99:59:59.999
We still have one initrd.

99:59:59.999 --> 99:59:59.999
And now I can say…

99:59:59.999 --> 99:59:59.999
Oh no, first I have to copy the dracut version
and then I can generate

99:59:59.999 --> 99:59:59.999
a new initrd with dracut.

99:59:59.999 --> 99:59:59.999
dracut uses the usual hooks or module
system,

99:59:59.999 --> 99:59:59.999
it does not use the hooks from the initramfs
things but it already includes

99:59:59.999 --> 99:59:59.999
a lot of hooks, so for example if you have
a cryptsetup,

99:59:59.999 --> 99:59:59.999
you do not need the hooks for
initramfs-tools from the cryptsetup package

99:59:59.999 --> 99:59:59.999
because dracut already includes this
and a lot of other things.

99:59:59.999 --> 99:59:59.999
After generating a new initrd,
you update your grub and you see

99:59:59.999 --> 99:59:59.999
we have now two entries in the grub.

99:59:59.999 --> 99:59:59.999
One with the old initrd which was created
by…

99:59:59.999 --> 99:59:59.999
the default one is the initrd which is
created by initramfs-tools

99:59:59.999 --> 99:59:59.999
and here you have the boot entry for
the new dracut initrd

99:59:59.999 --> 99:59:59.999
and it boots up and works.

99:59:59.999 --> 99:59:59.999
What we need is that more people are
using it and giving it a try.

99:59:59.999 --> 99:59:59.999
In your environment, on your hardware,
does dracut work?

99:59:59.999 --> 99:59:59.999
We had a discussion, like 5 years ago, if
Debian…

99:59:59.999 --> 99:59:59.999
When will Debian switch from initramfs-tools
to dracut?

99:59:59.999 --> 99:59:59.999
And still there's no real need because
initramfs-tools works for everybody

99:59:59.999 --> 99:59:59.999
but I think in the long term, we will
switch it,

99:59:59.999 --> 99:59:59.999
so please help us, write bug reports

99:59:59.999 --> 99:59:59.999
or just give it a try, if it works for you
or not.

99:59:59.999 --> 99:59:59.999
That's it.

99:59:59.999 --> 99:59:59.999
[Applause]
