Sébastien Blanc with DevOpsSpeakeasy at DevoxxMA 2022

0:00
so welcome everybody we are here at
0:03
devbox Morocco and I’m here with
0:05
Sebastian Blanc and I’m super happy of
0:08
having you here but why don’t you
0:10
introduce yourself yeah so thank you so
0:13
so I’m Sebastian Blanc uh I’m half
0:15
French half Dutch and that’s why I have
0:18
this weird accent I always say you know
0:19
weird but sexy accent yes and
0:24
um I’m a developer Advocate currently
0:26
working for Reddit even if yeah spoiler
0:28
alert I’m living Reddit in a few weeks
0:31
but I will still be a developer advocate
0:33
so my job is to make developers happy
0:36
and I really love my job yeah that and
0:41
you’re super good at it so if you
0:44
haven’t seen any of his sessions please
0:46
do so look for him and he’s very active
0:49
in YouTube Twitter so just follow him
0:53
you it’s it’s real interesting thank you
0:56
so you had a session today yeah I just
1:00
just about I just I just walked out from
1:03
my session almost well thank you very
1:05
much for being with us yeah yeah what
1:08
was your session about it so the the
1:10
title of my talk was accessing your
1:13
brain with an API
1:16
okay that so out my brain or your brain
1:19
whatever in this case it was mind brain
1:22
and um yeah I have this device that you
1:26
put on your skull and it can read the
1:28
Electric electrical activity from your
1:31
neurons and it can extract uh the the
1:35
alpha wave the Theta wave all the waves
1:37
and uh it’s make it’s available on an
1:41
API so those waves if you’re not a
1:44
neuroscientist doesn’t mean that much
1:46
for you but this API brings some
1:50
abstraction level so it can give you
1:52
your focus rate so Focus zero you’re not
1:57
focused at all one you’re super focused
1:59
never happened to me same for calm and
2:03
uh so once you have that you can start
2:05
playing with that and my opening demo is
2:08
I try to focus and if my focus go
2:12
above 1.5 I scale a pod in kubernetes
2:17
with my brain that is my opening demo oh
2:20
my God no it’s it’s super interesting
2:23
and you managed to do that ago and
2:25
managed to I managed to do that yeah
2:27
yeah so people could see me thinking
2:30
getting focused and seeing the pot going
2:33
to zero to three instances
2:36
okay so yeah so we have learned that a
2:39
there is a device out there b there is
2:42
an API that you can use it’s is the Java
2:44
API currency is a node.js library that
2:49
comes provided by the company that makes
2:51
this device but this device also can
2:55
provide its data to to another project
2:58
which is called brain flow which is an
3:00
open source project and there you have a
3:02
Java Library also a Rest Library a
3:04
python Library we can well manage all
3:09
those data filter them and so you can do
3:12
it with Java as well if you want yeah
3:13
well we also learned that you can train
3:17
your brain to focus and relax with this
3:19
kind of devices but the last part that
3:22
you do mention is actually what I like
3:25
the most there is an open source library
3:28
in different or with different languages
3:32
so tell us about your experience with
3:35
open source oh my experiences so um I’ve
3:38
been working out for 10 years for Reddit
3:40
so I know open source but I was doing
3:43
open source way before and that’s how we
3:46
met Yes actually yes I started with
3:50
contributing to a small project grills
3:52
uh awesome project you could make
3:54
plugins for that and the the really
3:56
first iPhone was out and I made a plugin
4:02
to make mobile websites with grills
4:06
and that was my first project
4:08
uh I remember Graham helped me and uh
4:12
and this was so my first contribution
4:13
and was also for me the first
4:16
opportunity to go on stage and talk
4:18
about it at girls exchange
4:21
um in London 2008 or something like that
4:24
and yeah that was a starting point and
4:27
then after a few years after I joined
4:30
Reddit where everything is open as you
4:32
know even the products yes and um yeah
4:36
uh and I’ve stopped contributing to
4:38
different projects uh even now as a
4:41
developer Advocate we often say you only
4:43
make demote which is partially true but
4:47
when I can I also contribute to quercus
4:50
for instance and contributing is also
4:52
while doing my demo I see something is
4:54
not working I open a ticket
4:56
exactly that is already uh a
4:59
contribution that it’s very valuable
5:01
don’t think that you need to actually
5:02
submit code sometimes only uh reporting
5:06
an issue should be a minimal test case
5:09
asking questions is more than enough
5:12
your contributions are very valuable
5:14
exactly and what you said uh always try
5:17
to to indicate the steps to reproduce
5:20
yourself because sometimes you have
5:22
issues doesn’t work no it has to be a
5:26
little bit more helpful for the
5:28
maintainers yes you know I know we
5:30
actually had Graham right in the morning
5:34
talking about exactly he was also
5:36
talking about his pad and he was talking
5:39
about grills and open stores how how we
5:43
need good documentation for people to
5:46
come near open source so everything
5:49
comes back like everything is part of a
5:52
circle a cycle here exactly a virtual
5:55
cycle yeah yeah yeah yeah I love it’s so
5:58
powerful uh open source even more than
6:01
we’ve
6:02
that we think and even for Innovation
6:05
for for for everything for for the new
6:09
generation that is coming because we say
6:11
software is eating the world and and
6:13
it’s true
6:15
um in 20 years our health uh turned
6:19
presentation everything will be
6:20
regulated with software and it and then
6:24
it must not be a black box it must be
6:26
available for everyone to know how our
6:29
life is regulated okay so that’s why
6:34
open source is also important what would
6:37
you recommend to newcomers to to our
6:40
industry to new developers what what I
6:43
mean we have been in this industry for
6:45
quite a long time yeah so what would you
6:49
tell them a developer that would like to
6:52
contribute to open first Yeah well yeah
6:53
I mean they’re like imagine that they
6:56
are new out out of the school or out of
7:00
the trainings okay so so uh out of
7:03
school
7:04
um well I will come back and I’m sorry
7:06
because the best way of making a great
7:09
CV of yourself especially in the
7:10
beginning when you don’t have work
7:12
experience is starting contributing to
7:15
an open source project and and
7:18
don’t be afraid of doing that uh find a
7:21
project that you like
7:23
stay there for a few few days reading a
7:27
bit of mailing lists feel the spirit of
7:29
it and to juice yourself and then look
7:32
if there’s an issue that you could uh
7:34
fix or a small feature that you could
7:37
introduce or just fixing the
7:39
documentation and just do it and uh it’s
7:43
really easy the communities are awesome
7:46
my best friends are come from all those
7:49
communities so it’s not only for your
7:51
work it’s good stuff for your life it
7:53
will be good so so my advice main advice
7:56
is don’t be afraid
7:58
it’s easy uh and yeah people will be
8:02
around you to help you always I thank
8:05

8:09
my fourth time I was there in Casablanca

8:46
bother you because he was he was I mean
