0:00:07.254,0:00:07.504
Right, good afternoon

0:00:07.817,0:00:12.360
It is the lightning talks sessions at[br]DebConf Hamburg 2018

0:00:13.019,0:00:17.895
We've got seven speakers, and I guess[br]we'll just get going

0:00:18.352,0:00:22.107
Starting with Tobias Platn???,[br]talking about Debian on Power9.

0:00:27.528,0:00:36.302
Yesterday I, hm no, on friday,[br]I received my new Power9 machine.

0:00:36.519,0:00:37.710
A Talos 9 (II).

0:00:40.456,0:00:44.680
And it has an IBM Power9 processor

0:00:45.658,0:00:52.946
So, the only distro that I know that will[br]work is Debian.

0:00:55.748,0:01:01.820
Then, this is a new PowerPC 64 bits[br]architecture,

0:01:02.330,0:01:06.553
that can run in little-endian mode.

0:01:07.255,0:01:10.823
I downloaded a Debian installer.

0:01:11.834,0:01:16.531
First, I chosed the stable version, but

0:01:17.492,0:01:21.211
that crashed during install.

0:01:21.733,0:01:28.208
And, then I retried a different version,[br]a daily version.

0:01:29.265,0:01:37.455
And this one, which is based on Buster,[br]correctly installed.

0:01:38.264,0:01:44.682
I can even have a graphical environment,[br]working out of the box.

0:01:45.696,0:01:52.899
And, the installer then complained that[br]there is no boot partition

0:01:53.862,0:02:04.744
for older PowerPCs, and this boot partition is[br]not needed, since the TalosII

0:02:05.162,0:02:13.166
has a newer systems starting with power7[br]used petitboot.

0:02:16.038,0:02:22.581
So, that needs to be fixed in the Debian[br]installer,

0:02:23.259,0:02:29.066
that it doesn't produce the warning[br]on Power machines.

0:02:32.143,0:02:37.359
And now I have a working Debian[br]installation,

0:02:38.079,0:02:40.300
which I can use.

0:02:49.707,0:02:52.912
(thanks) [applause]

0:02:54.093,0:02:55.411
Thank you very much, that was very quick.

0:02:55.639,0:02:57.328
Next up is Thimothée Jaussoin,

0:02:57.890,0:03:01.721
talking about Movim, the XMPP social[br]platform.

0:03:05.572,0:03:07.427
Give him a moment to get set up.

0:04:32.681,0:04:34.262
I think it's a bit better this way.

0:04:34.755,0:04:36.976
Who already heard about the platform Movim?

0:04:38.679,0:04:44.207
OK, so we have a couple of people that[br]know about the project here.

0:04:45.054,0:04:48.307
Just to present you what I ??? could be a[br]parallel universe

0:04:48.481,0:04:50.653
but is actually the current universe we're[br]living with.

0:04:52.233,0:04:54.307
Lots of different chat platforms.

0:04:54.594,0:04:56.036
The same thing on social networks.

0:04:56.779,0:05:00.051
We keep reinventing the wheel[br]all the time.

0:05:02.563,0:05:03.455
We don't have this problem with e-mails

0:05:03.742,0:05:07.157
hopefully actually the e-mail standards[br]came way before before all of those

0:05:08.182,0:05:09.515
proprietary solutions

0:05:10.092,0:05:15.089
So we have ??? and Google and Microsoft[br]are still using SMTP, IMAP, for now.

0:05:15.567,0:05:19.559
So everything is compatible, and we have[br]a lot of clients on top of that.

0:05:19.773,0:05:21.747
But for chat, and social networks, it's[br]not the case.

0:05:22.750,0:05:26.054
So the idea of Movim is to build a[br]social platform.

0:05:28.958,0:05:32.801
In there, we can put a little couple of[br]ingredients.

0:05:33.414,0:05:37.407
First, it needs to be Open-Source, for the[br]transparency, for the fact that you can

0:05:37.584,0:05:41.829
have feedback and improvements,[br]for the security part. Bring some trust

0:05:42.035,0:05:47.128
I think that you guys here know about the[br]advantages of Free Software, and

0:05:47.578,0:05:52.731
especially on the communication part,[br]on social networks, but it's not enough.

0:05:53.745,0:05:56.915
We also need to be in control, actually[br]in this social network.

0:05:57.382,0:05:59.249
So it need to be simple and transparent

0:05:59.532,0:06:02.121
on the UI but also on the protocol level.

0:06:02.345,0:06:07.222
On the really deep below stacks.

0:06:08.183,0:06:10.276
So we'll need to have a strong and reliable[br]encryption,

0:06:10.493,0:06:14.743
so don't reinvent also an encryption[br]- talking about Telegram, here -

0:06:15.987,0:06:19.209
And, yeah, need some trusts in sights[br]here.

0:06:19.439,0:06:22.300
I mean a community, and not a company[br]that you will blindly trust

0:06:22.844,0:06:25.718
to take care of all of your communications.

0:06:25.937,0:06:26.953
But it's not enough.

0:06:27.661,0:06:32.071
It needs to be decentralized. Because[br]centralized social networks,

0:06:32.274,0:06:33.482
even if it's opensource,

0:06:33.687,0:06:36.727
if it's only one instance, you have to[br]still trust the instance. So would like to

0:06:36.917,0:06:39.509
deploy your instance, you would like to[br]trust someone else,

0:06:39.674,0:06:42.656
you can only, sometimes, trust only[br]yourself in seldom cases

0:06:44.050,0:06:46.627
Decentralization also brings robustness

0:06:50.497,0:06:54.605
So that's too many times that actually[br]one server is failing, think Signal

0:06:55.078,0:06:59.115
had an issue recently, about this kind[br]of thing there.

0:06:59.272,0:07:02.567
The issue was with the Amazon servers,[br]the whole thing didn't worked

0:07:02.731,0:07:04.077
for a couple of hours.

0:07:04.429,0:07:06.660
And then, resist against censorship and[br]control.

0:07:06.865,0:07:09.145
Same thing with Telegram, I think in[br]Russia.

0:07:09.307,0:07:13.995
I'm talking more about the IM part, but[br]it's also applicable to social networks.

0:07:14.179,0:07:18.439
It's exactly the same thing, just that the[br]exchanges of information are a bit different.

0:07:18.976,0:07:20.749
So, you need these steps but

0:07:21.552,0:07:23.845
all those platforms here

0:07:24.962,0:07:33.484
(I just made this conference 3 years [br]ago, just added Mastodon recently)

0:07:37.125,0:07:43.934
So i might talk about different sorts[br]of platforms

0:07:44.452,0:07:46.932
There is communication between those[br]platforms, kind of standards that are

0:07:47.108,0:07:50.036
starting to come in, especially between[br]Diaspora and Mastodon,

0:07:50.257,0:07:51.944
but there is still a lot of work to do[br]there.

0:07:52.828,0:07:56.406
So, the secret ingredient is about[br]compatibility, about extensibility.

0:07:56.885,0:07:58.634
Don't try to reinvent the wheel again,

0:07:58.843,0:08:00.232
don't try to create another social network,

0:08:00.612,0:08:03.790
or another IM platform that will have all[br]those communication troubles.

0:08:04.145,0:08:05.253
So, I mean a long-term vision.

0:08:07.652,0:08:10.517
And, actually, the secret ingredient[br]is standardization, in these things.

0:08:11.240,0:08:18.348
So, this standard should[br]have a couple of features,

0:08:19.535,0:08:23.706
support news feeds, communities, IM, chatroom[br]presences, know who's online, profiles,

0:08:24.084,0:08:26.961
video conferencing security, bridges to the Web.

0:08:28.240,0:08:29.524
And then it will be real-time.

0:08:31.799,0:08:32.973
And, 1 minute?

0:08:33.451,0:08:35.350
This protocol actually exists, it's called[br]XMPP.

0:08:36.176,0:08:40.060
So the goal of the project is:[br]- take XMPP implemented

0:08:40.710,0:08:43.859
- and doing a lot of innovation on[br]top of the project

0:08:44.493,0:08:48.857
So, server-side it's a simple XMPP[br]client, webserver, simple to install

0:08:49.342,0:08:51.121
(PHP, MySQL PostgreSQL)

0:08:51.684,0:08:55.472
And user-side, it's also super simple[br]to use, you need simply a browser,

0:08:57.505,0:09:02.207
it's responsive, it's light, it's fast and[br]is built actually for small communities.

0:09:03.426,0:09:05.195
There are pods all around the world.

0:09:05.471,0:09:07.347
You're really invited to deploy your own[br]pods.

0:09:07.834,0:09:11.255
There is already ten thousands accounts[br]on the official pod

0:09:11.470,0:09:12.417
30 languages

0:09:12.651,0:09:13.889
Debian packages coming soon

0:09:14.137,0:09:16.619
Thanks to the help of some people[br]in this room.

0:09:17.506,0:09:19.666
And, that's it !

0:09:20.578,0:09:22.690
So if you want more information,[br]everything is on the website,

0:09:22.913,0:09:25.174
you can join the chat room.

0:09:25.385,0:09:26.527
Or, the twitter.

0:09:27.210,0:09:30.576
[applause]

0:09:31.005,0:09:32.163
Thank you very much.

0:09:32.620,0:09:35.902
Next up is Thomas Lange, Mrfai,[br]talking about dracut.

0:09:58.997,0:10:02.293
Today, I'm not talking about FAI[br]but about dracut.

0:10:02.895,0:10:10.278
dracut is a replacement for initramfs[br]which is used by most other distributions.

0:10:11.204,0:10:18.435
If I'm correct, only Ubuntu and Debian[br]and derivatives are using initramfs-tools

0:10:18.765,0:10:22.640
All other distributions already moved[br]to dracut.

0:10:24.015,0:10:28.810
Today I want to show how you can get[br]an experience with dracut

0:10:29.261,0:10:31.800
without deinstalling initramfs-tools.

0:10:32.749,0:10:37.485
Ben Hutchings did some patches, I think[br]two years ago, so it's possible.

0:10:38.598,0:10:41.847
What you have to do, there's a package[br]called "dracut-core",

0:10:42.197,0:10:44.074
which does not conflict with[br]initramfs-tools.

0:10:46.684,0:10:49.213
I have a virtual machine.

0:10:51.931,0:10:55.228
So, debian/fai…

0:10:55.926,0:11:03.568
On this machine, I will now install[br]the dracut-core package

0:11:05.357,0:11:07.007
and that's it.

0:11:08.395,0:11:10.536
We still have one initrd.

0:11:14.012,0:11:15.192
And now I can say…

0:11:15.448,0:11:33.986
Oh no, first I have to copy the dracut version[br]and then I can generate

0:11:34.317,0:11:36.178
a new initrd with dracut.

0:11:38.818,0:11:44.576
dracut uses the usual hooks or module[br]system,

0:11:45.187,0:11:50.659
it does not use the hooks from the initramfs[br]things but it already includes

0:11:50.881,0:11:54.554
a lot of hooks, so for example if you have[br]a cryptsetup,

0:11:54.799,0:12:02.635
you do not need the hooks for[br]initramfs-tools from the cryptsetup package

0:12:03.233,0:12:07.911
because dracut already includes this[br]and a lot of other things.

0:12:08.515,0:12:13.878
After generating a new initrd,[br]you update your grub and you see

0:12:14.291,0:12:16.388
we have now two entries in the grub.

0:12:17.587,0:12:21.194
One with the old initrd which was created[br]by…

0:12:22.362,0:12:26.695
the default one is the initrd which is[br]created by initramfs-tools

0:12:27.371,0:12:32.660
and here you have the boot entry for[br]the new dracut initrd

0:12:33.389,0:12:35.476
and it boots up and works.

0:12:41.613,0:12:47.606
What we need is that more people are[br]using it and giving it a try.

0:12:48.404,0:12:51.625
In your environment, on your hardware,[br]does dracut work?

0:12:53.096,0:12:57.393
We had a discussion, like 5 years ago, if[br]Debian…

0:12:57.787,0:13:01.490
When will Debian switch from initramfs-tools[br]to dracut?

0:13:02.462,0:13:06.332
And still there's no real need because[br]initramfs-tools works for everybody

0:13:06.901,0:13:09.392
but I think in the long term, we will[br]switch it,

0:13:09.844,0:13:13.895
so please help us, write bug reports

0:13:14.224,0:13:16.318
or just give it a try, if it works for you[br]or not.

0:13:17.030,0:13:18.113
That's it.

0:13:18.816,0:13:23.597
[Applause]

0:13:24.111,0:13:27.810
Next up is TecKids talking about[br]their organization.

0:14:18.637,0:14:24.767
Ok, those of you who attended the[br]Skolelinux talk already heard about TecKids.

0:14:24.987,0:14:27.369
I want to give a few details about what[br]else we do.

0:14:28.932,0:14:33.079
TecKids is a non-profit organization based[br]in Germany, but

0:14:33.373,0:14:37.919
we're working internationally and

0:14:42.814,0:14:48.200
we are completely centered around free[br]software and we do basically everything

0:14:49.607,0:14:54.605
concerning free software in education in[br]the context of children and adolescents,

0:14:54.605,0:14:55.348
young people.

0:14:55.859,0:14:58.733
More than 50% of our active members[br]are minors.

0:14:59.882,0:15:01.244
There's an "s" missing, sorry.

0:15:01.858,0:15:03.858
They are of course not minor but they are[br]minors.

0:15:06.570,0:15:08.807
Sorry, kids, if you are watching this.

0:15:10.388,0:15:13.283
They're minors and we are a fully[br]democratic organization

0:15:13.656,0:15:15.186
like in the FOSS spirit

0:15:16.214,0:15:20.979
and the most important thing is that we[br]get children involved with all the parts

0:15:21.191,0:15:25.143
of the organization, both operational and[br]tutoring and workshops

0:15:25.604,0:15:28.882
and working with free software projects,[br]giving presentations.

0:15:29.888,0:15:34.253
Normally some children would be here but[br]as this conference was right in the middle of

0:15:34.767,0:15:37.058
schooltime, this was not so easy.

0:15:38.226,0:15:39.264
So what do we do.

0:15:39.549,0:15:43.420
First of all, we want to get children[br]interested in programming, in coding,

0:15:43.911,0:15:46.092
in technical stuff and also in free software.

0:15:46.752,0:15:50.299
This we do by running youth programs[br]at free software conferences

0:15:50.551,0:15:55.835
like the FrOSCon where normally around[br]100 to 120 children attend and

0:15:56.613,0:16:00.710
use Debian and all that cool stuff and[br]learn what they can do with it.

0:16:04.489,0:16:09.320
We do peer learning, so those children[br]who already know many things and

0:16:09.757,0:16:12.775
are very interested, they start tutoring[br]other children.

0:16:14.380,0:16:18.854
Of course we have non-tech fun together,[br]we are outside,

0:16:19.397,0:16:23.999
there is a social program with staying[br]over night, having a barbecue and

0:16:24.758,0:16:27.808
all that stuff that helps building[br]a community.

0:16:29.316,0:16:33.515
Those who are even more interested can get[br]actively involved in preparing workshops,

0:16:33.768,0:16:38.764
organizing events, preparing talks, looking[br]at open source projects,

0:16:39.223,0:16:44.998
helping others get a free messenger[br]instead of WhatsApp,

0:16:45.373,0:16:50.310
working on HowTo, how to spread the word[br]among youths and all of that.

0:16:51.243,0:16:54.366
And then visit conferences and raise[br]awareness,

0:16:54.555,0:16:56.107
this is our presentation team from[br]the Chemnitz Linux Days

0:16:57.346,0:17:00.468
and they are presenting the whole[br]"can" of free software in education

0:17:00.918,0:17:05.282
at our SchulFrei booth which is[br]"School free" in German.

0:17:08.777,0:17:15.129
They are presenting all projects that are[br]involved in this common booth and

0:17:17.934,0:17:19.521
care for free software education.

0:17:21.212,0:17:25.395
If you are interested in that, maybe[br]because you have children or

0:17:25.608,0:17:29.158
want to have children or are involved[br]in education in some way,

0:17:30.942,0:17:33.780
there are quite a few things that you[br]can do.

0:17:34.447,0:17:40.196
You can help working on projects, you[br]can work with mentoring the children

0:17:41.019,0:17:43.900
in coding or organisational activities.

0:17:45.621,0:17:48.478
You can help spreading the word, also[br]raising awareness that

0:17:49.592,0:17:55.599
many many software projects do have[br]some involvement with children,

0:17:55.911,0:17:59.507
even indirectly, like a web browser[br]like Firefox,

0:18:00.018,0:18:03.696
such applications are used by children and[br]they may have other needs,

0:18:03.994,0:18:05.484
and they may have other views on that,

0:18:05.884,0:18:10.307
so it's very important to at least think[br]about what children or schools or

0:18:11.705,0:18:14.077
teachers as well do with this software.

0:18:14.746,0:18:16.213
Pardon? One minute, thank you.

0:18:18.071,0:18:20.443
We need help with presentations at[br]conferences,

0:18:21.071,0:18:28.509
so not every time the same people have to[br]get a day off at work and travel to conferences

0:18:29.072,0:18:30.883
there's much more manpower needed.

0:18:31.361,0:18:37.428
And of course, every ngo, every non-profit[br]organization is lacking money,

0:18:37.840,0:18:41.667
so if you have already donated to Debian[br]and still have money left,

0:18:42.131,0:18:47.389
you might want to give your money to[br]the future, which is children.

0:18:50.346,0:18:52.192
Don't forget donating to Debian.

0:18:52.587,0:18:54.959
I don't know if I am shot if I don't say that.

0:18:57.299,0:19:02.778
And there's also liberapay, it's a free[br]donation platform,

0:19:03.041,0:19:06.531
just have a look at it and if you want to[br]help us, actively just go to our web site,

0:19:06.785,0:19:11.504
find some communication means or just[br]talk to someone you find

0:19:11.748,0:19:15.604
at any conference who is wearing this[br]shirt with our logo.

0:19:16.069,0:19:17.077
Thank you.

0:19:17.684,0:19:22.524
[Applause]

0:19:38.988,0:19:41.637
Next up is Thomas Koch, talking about[br]containers.

0:19:48.654,0:19:49.555
Almost ready.

0:19:49.875,0:19:50.140
We do have one more space at the end[br]if anybody feels, you know,

0:19:50.140,0:19:58.512
inspired to tell us all the things.

0:19:58.829,0:20:02.525
I mean, we did have one very last minute[br]sign up.

0:20:24.490,0:20:26.843
Meanwhile, I guess I can make[br]announcements while I'm here.

0:20:27.185,0:20:30.678
Front desk will be available again[br]after lunch, as will t-shirts.

0:20:30.896,0:20:32.562
Anybody who hasn't had a t-shirt yet,

0:20:33.887,0:20:37.205
basically, if you signed up, you're allowed[br]to get a t-shirt, come see me,

0:20:37.895,0:20:39.618
yes, free of charge,

0:20:40.941,0:20:43.656
come see me at front desk when it's[br]open again after lunch.

0:20:45.298,0:20:48.518
Because I do know some people been[br]reticent to come up and, you know,

0:20:48.754,0:20:49.577
ask one…

0:20:55.199,0:20:59.037
I've probably given effectively[br]a lightning talk on not giving…

0:21:09.754,0:21:12.220
Hello, I'm Thomas Koch, I work for Google,

0:21:12.570,0:21:17.694
I work in support for Google Container[br]Engine, Google kubernetes engine.

0:21:20.232,0:21:22.982
Who knows what Kubernetes is?

0:21:26.102,0:21:27.158
Oh, so few, ok.

0:21:27.782,0:21:33.565
It's a thing to orchestrate containers[br]on many many nodes,

0:21:34.205,0:21:35.666
up to thousands of nodes.

0:21:36.471,0:21:42.960
It was started by Google, open sourced[br]by Google in 2015 I believe.

0:21:44.408,0:21:49.983
First contributor was Red Hat, it is 100%[br]open source, it's written in Go

0:21:50.545,0:21:58.400
and by now it has won the market of[br]managing containers on large nodes.

0:21:59.088,0:22:05.240
I just was at the KubeCon in Copenhagen[br]with 4300 participants and

0:22:05.605,0:22:09.472
every company you can imagine has[br]an offering about Kubernetes.

0:22:11.668,0:22:16.894
Just some logos of companies that use or[br]contribute to Kubernetes

0:22:17.746,0:22:22.350
and even more logos and these slides are[br]outdated, so there are even more.

0:22:23.840,0:22:30.571
Kubernetes, you have some masters that[br]control kubelet on every node.

0:22:31.065,0:22:36.105
A kubelet can start containers and can[br]set up networking stuff

0:22:36.570,0:22:43.506
and can set up volumes and the basic[br]concept of computation,

0:22:43.960,0:22:45.884
the basic primitive is a pod.

0:22:46.267,0:22:51.531
A pod is one to many containers running[br]together in one environment

0:22:51.971,0:22:57.385
so that you have the possibility to have[br]sidecars running beside your main containers

0:22:57.753,0:22:59.092
that does additional stuff.

0:22:59.703,0:23:05.648
It has proven useful in Google's internal[br]??? container management engine

0:23:06.060,0:23:09.967
that you want to have certain containers[br]always running containers

0:23:10.167,0:23:11.497
and sharing resources.

0:23:12.356,0:23:14.400
An other important primitive is volumes.

0:23:14.932,0:23:20.593
Kubernetes can manage your storage and[br]provision storage to be accessible

0:23:20.964,0:23:22.135
to your containers.

0:23:23.683,0:23:31.443
You can combine many parts that provide[br]the same service to be accessible

0:23:31.767,0:23:37.545
under the same IP address and so have[br]failover enable like this

0:23:37.896,0:23:42.648
and of course then you have controlers[br]that scale your services,

0:23:43.080,0:23:46.081
scale down your services, restart failed[br]pods

0:23:48.807,0:23:51.719
or drain nodes that you want to take away

0:23:54.724,0:23:59.654
And my question now is what is the role[br]of Debian in a world where

0:23:59.949,0:24:05.934
Kubernetes becomes more and more popular[br]even if not that many of you have heard about it

0:24:08.024,0:24:13.391
I believe that Kubernetes will become[br]even more popular

0:24:14.581,0:24:20.325
and even as a Debian Maintainer, I'm[br]enthusiastic about how easy it becomes now

0:24:20.625,0:24:23.024
to run your stuff in Kubernetes.

0:24:24.522,0:24:30.670
But you only need a very minimal host[br]operating system to install Kubernetes

0:24:31.084,0:24:37.966
on your servers, afterwards you need[br]a bare image, a base image for your container

0:24:38.401,0:24:40.666
which is normally also a very minimal image

0:24:41.250,0:24:45.640
and you don't do "apt-get install apache2"[br]anymore to have a web server,

0:24:46.058,0:24:52.008
you take an apache container image and then[br]you extend this image and

0:24:52.483,0:24:59.501
put your app onto this image, so you don't[br]need an apache Debian image anymore

0:24:59.790,0:25:01.332
in such a world.

0:25:02.589,0:25:05.108
Will we still need this in Debian?

0:25:06.625,0:25:09.106
However, nothing is perfect.

0:25:09.485,0:25:13.108
On KubeCon, I also saw companies offering

0:25:13.695,0:25:17.865
"Oh, we scan you container images for[br]outdated libraries" and

0:25:19.579,0:25:27.290
you have long times to update your cluster[br]because all the containers need to be stopped

0:25:28.247,0:25:31.736
you download new images, you start whole[br]new environments

0:25:33.542,0:25:36.251
so there are optimizations possible there

0:25:37.320,0:25:38.560
and people are wondering

0:25:38.799,0:25:41.359
"Ok, where does my stuff come from?[br]Is it from a trusted source?"

0:25:43.125,0:25:46.330
And my crazy thoughts, maybe it's an[br]opportunity here

0:25:46.753,0:25:52.337
if Debian would become a source of trusted[br]binaries or even container images.

0:25:53.622,0:25:54.568
Thank you.

0:25:55.191,0:26:00.211
[Applause]

0:26:01.248,0:26:09.735
Next up, Pierre Pronchery, talking about[br]Manticore, DeepState and DeforaOS

0:26:11.854,0:26:13.887
Are you pretty much ready?

0:26:14.748,0:26:15.636
I think so.

0:26:32.528,0:26:36.072
Meanwhile, does anybody know any[br]dance routines, you know,

0:26:37.193,0:26:40.230
just to bridge over the time, because[br]I'm not going to.

0:26:46.011,0:26:47.700
I don't think I know any Jerks.

0:26:50.969,0:26:52.485
Hopefully nearly there.

0:26:53.303,0:26:56.427
You fling my phone from me.

0:26:57.424,0:26:59.260
It's ok, nobody calls me anyway.

0:27:24.172,0:27:27.253
I'm afraid I haven't got any more[br]announcements.

0:27:32.435,0:27:35.911
We are pleased to announce that there[br]are no current announcements available.

0:27:43.322,0:27:44.767
The news has been called off.

0:27:50.848,0:27:52.601
Do you actually have slides?

0:28:00.817,0:28:02.660
I'm wondering if we should swap you around

0:28:05.024,0:28:10.001
Ok, right, we have the interval act, an[br]interpretive dance by Andrew Shadura

0:28:10.224,0:28:12.888
on the nature of git crecord being[br]for the win.

0:28:17.951,0:28:20.203
Well, you know, anything to bridge[br]the time, right?

0:28:51.746,0:28:53.401
If in doubt, make the font bigger.

0:28:56.452,0:28:58.462
Maybe I should give a lightning talk[br]about that.

0:29:01.773,0:29:06.242
I think I might, just at the very end, I'll[br]just disguise it as an announcement.

0:29:07.700,0:29:08.683
Ready?

0:29:10.262,0:29:11.313
There, no.

0:29:11.798,0:29:12.936
I prefer that.

0:29:13.674,0:29:14.801
Yes, but we don't.

0:29:15.569,0:29:16.303
Why?

0:29:17.023,0:29:18.340
Did you see what happened earlier?

0:29:18.936,0:29:20.285
What happened earlier?

0:29:26.600,0:29:27.895
Please use the hand microphone.

0:29:28.361,0:29:28.839
Ok.

0:29:30.388,0:29:32.603
Alright, listen to a man but not me.

0:29:33.624,0:29:34.403
[laughter]

0:29:48.357,0:29:48.914
Can you hear me?

0:29:49.493,0:29:54.927
So, I'm just going to show you a small[br]utility I wrote.

0:29:55.241,0:29:59.386
Actually, I didn't write it from scratch,[br]I just ported it from… Anyway.

0:30:00.056,0:30:02.696
Let's see, we've got a git diff of

0:30:04.068,0:30:06.932
things with a Debian package.

0:30:07.458,0:30:09.978
Lot's of changes, and I forgot to commit[br]them individually.

0:30:10.550,0:30:13.882
There's lots of patches and things,

0:30:14.547,0:30:16.723
I just want to, somehow, sort this out.

0:30:17.355,0:30:23.875
So I just run "git crecord" and suddenly[br]I can see all the things here.

0:30:24.255,0:30:26.396
I can unwrap the diffs…

0:30:28.140,0:30:30.085
What's happening with the ???

0:30:31.213,0:30:36.839
I can basically select individual bits[br]of the diff and…

0:30:39.179,0:30:44.535
Let's just deselect all things, commit[br]those, just a few.

0:30:45.063,0:30:47.027
There were just a few patches refreshed

0:30:47.949,0:30:53.731
so I'm going to commit them now,[br]yes, like refresh patches.

0:30:57.408,0:30:59.635
Let's say just "Refresh", just enough.

0:31:01.594,0:31:02.526
Oh, mmh.

0:31:05.276,0:31:08.774
It's not going to work, because I haven't[br]got a card

0:31:09.270,0:31:10.606
and I forgot to disable the…

0:31:12.061,0:31:17.784
I don't think I can, I don't remember,[br]I probably can't disable PGP signing unfortunately

0:31:18.049,0:31:19.386
it's not implemented yet.

0:31:20.120,0:31:20.583
Anyway.

0:31:22.245,0:31:24.611
Using this thing you can, it's better than…

0:31:27.406,0:31:29.343
How is it properly called.

0:31:30.484,0:31:32.971
It's better than the builtin git thing ...

0:31:33.222,0:31:34.412
I can't even remember it's name.

0:31:40.455,0:31:40.969
That one

0:31:47.384,0:31:52.192
I didn't exactly hear exactly what he said,[br]like "git patch something"

0:31:54.953,0:31:57.800
"git add --patch"

0:31:58.369,0:31:59.653
And there's an other one which is…

0:32:00.096,0:32:03.234
There's one a bit more interactive and[br]one which is a bit less interactive.

0:32:04.570,0:32:06.672
This is mega interactive and there[br]will be more features.

0:32:07.172,0:32:09.385
It is actually, it was originally written[br]for mercurial

0:32:10.150,0:32:13.497
and this was a thing I really missed[br]when I had to use git

0:32:14.072,0:32:15.768
and now I don't have to anymore.

0:32:16.670,0:32:17.670
This is it.

0:32:18.434,0:32:21.675
It's in Debian, you can apt install it[br]if you prefer.

0:32:23.073,0:32:26.647
It's in Debian, you can apt install it[br]if you prefer,

0:32:27.338,0:32:29.940
or you can install it from source and[br]there would be more features later.

0:32:30.809,0:32:32.215
That's it.

0:32:33.074,0:32:34.449
Thank you

0:32:35.015,0:32:37.464
[Applause]

0:32:38.585,0:32:42.116
Now, Pierre Pronchery talking about[br]all the things that I said

0:32:42.553,0:32:43.803
he was going to talk about earlier.

0:32:52.500,0:32:53.424
One moment please.

0:33:29.801,0:33:31.837
[Applause]

0:34:35.400,0:34:37.480
Sorry about that, I didn't really plan[br]for this,

0:34:37.846,0:34:39.524
so I made the slides 5 minutes ago.

0:34:40.098,0:34:42.057
So, I'm Pierre Pronchery, thank you[br]for having me,

0:34:42.615,0:34:45.002
even if I'm actually an officiel NetBSD[br]developer,

0:34:45.844,0:34:48.540
but I'm been using Debian since 1999,[br]so maybe I'm alowed,

0:34:49.547,0:34:53.456
I'm also a security consultant, interested[br]in Kernel development,

0:34:53.807,0:34:55.254
security integration, and so on.

0:34:56.121,0:34:57.822
What you cannot see on the slides[br]right now is that

0:34:58.151,0:35:00.114
I'm also on the board of directors[br]of NetBSD.

0:35:00.955,0:35:04.285
So actually I'm in a good position to talk[br]about the project if you'd like to.

0:35:05.784,0:35:07.701
I would like to talk to you about Manticore[br]today.

0:35:08.832,0:35:10.363
It's a symbolic execution tool,

0:35:10.749,0:35:14.472
basically, it uses a CPU emulator, which[br]can be hardware assisted of course,

0:35:15.122,0:35:20.555
to run and analyze programs or algorithms,[br]so parts of programs on a simulated system

0:35:21.617,0:35:23.464
and one of the aims is actually[br]to make them crash

0:35:23.778,0:35:29.413
so to make extensive fuzzing and be very[br]efficient at fuzzing by possibly tracing

0:35:30.578,0:35:34.336
instructions and so on, whatever is going[br]on inside the program.

0:35:35.575,0:35:39.901
It supports static Linux binaries in 32-bits[br]and 64-bits modes,

0:35:40.261,0:35:45.858
also it supports ARM 32-bits, support is[br]ongoing for ARM 64-bits,

0:35:46.300,0:35:48.743
it also works with Ethereum bytecode.

0:35:49.634,0:35:54.293
There are official releases on GitHub,[br]it's already packaged in PkgSrc by myself

0:35:55.222,0:35:57.941
and I'm actually looking for volunteers[br]to package it for Debian

0:35:58.459,0:36:00.249
or possibly help me to do so.

0:36:01.834,0:36:05.226
I'm actually sponsored by Trail of Bits,[br]the developer of Manticore,

0:36:05.616,0:36:08.123
to work on this, which is also why[br]I'm here.

0:36:09.880,0:36:12.704
The companion to Manticore is called[br]DeepState,

0:36:13.437,0:36:17.340
it's specifically meant for Unit Testing[br]with symbolic execution.

0:36:18.090,0:36:22.083
It supports not just Manticore but also[br]an other backend for analyzing

0:36:22.717,0:36:25.491
running binaries,

0:36:25.812,0:36:30.765
It's called angr, this other backend,[br]which was developed as a side node

0:36:31.072,0:36:33.392
for the Cyber Grand challenge[br]of DARPA last year.

0:36:34.849,0:36:38.285
DeepState is currently packaged[br]in 2 separate packages in PkgSrc

0:36:38.609,0:36:39.559
by myself again,

0:36:39.977,0:36:42.358
unfortunately not yet fully upstream[br]in PkgSrc,

0:36:42.765,0:36:47.384
but basically I made one package with[br]??? binaries and then the Python bindings.

0:36:48.221,0:36:50.747
This is also on GitHub but with no official[br]release yet,

0:36:51.070,0:36:52.822
because this is a very young project still

0:36:53.528,0:36:56.054
so I'm also for a volunteer in Debian[br]to help me package that.

0:36:57.415,0:37:01.975
And then, a shameless addition, I'm also[br]a developer of, the main developer of

0:37:02.208,0:37:07.135
DeforaOS, an open source desktop[br]environment, and with some more parts

0:37:07.554,0:37:08.361
in the project,

0:37:08.720,0:37:11.045
I have about 50 repositories now in this.

0:37:12.210,0:37:16.718
I'm therefore also looking for volunteers[br]to package that into Debian,

0:37:16.959,0:37:19.662
there are still projects we haven't[br]packaged yet, as far as I know.

0:37:21.113,0:37:25.432
So, since I'm here, I figured I could[br]as well get my PGP key signed,

0:37:26.382,0:37:28.467
I suppose it's one of the steps to become[br]a developer

0:37:28.797,0:37:31.651
and if there are more, I've heard[br]there are plenty,

0:37:33.129,0:37:37.956
then please help me out with this, I'll[br]welcome any assistance doing that.

0:37:38.812,0:37:41.575
Alright. Thank you.

0:37:42.084,0:37:45.350
[Applause]

0:37:45.782,0:37:46.719
Thank you very much.

0:37:47.091,0:37:48.296
I guess that's it.

0:37:48.613,0:37:52.756
The next lightning talk session that I'm[br]aware of is at DebConf18 in Taiwan.

0:37:53.158,0:37:54.843
I hope to see as many of you as possible[br]there.

0:37:55.488,0:37:57.452
Off you go, lunch time.

0:37:58.286,0:38:01.835
[Applause]
