1. About while42
0. FRENCH ONLY
TO BECOME A MEMBER OF WHILE42 YOU SHOULD BE EITHER A FRENCH TECH OR SOMEONE
SPEAKING FRENCH AND HAVING A COMPUTER SCIENCE DEGREE DELIVERED BY A FRENCH
SCHOOL / UNIVERSITY.
1. TECH ENGINEERS ONLY
ALL WHILE42 MEMBERS ARE TECH ENGINEERS (DEVELOPERS, OPS, DEVOPS, SYSADMIN, INGENIEURS INFORMATICIENS, CTO ...) AND/OR HAVE A DEGREE FROM A FRENCH
ENGINEERING TECH SCHOOL (EPITECH,SUPINFO, EPITA, ...). THERE IS NO FILTER BY
DEGREE OR SCHOOL. YOU DO NOT HAVE TO HAVE A DEGREE TO JOIN AS SO ON AS YOU ARE A
TECH ENGINEER (AND FRENCH).
2. REAL NETWORK, REAL PEOPLE
EVERYBODY SHOULD KNOW EACH OTHERS IN EACH CHAPTER. THE GOAL IS NOT TO BE AS
BIG AS POSSIBLE. WE DO NOT WANT TO BE A BIG ORGANIZATION WHERE YOU DON‟T KNOW
WHO IS STANDING NEXT TO YOU. THUS WE WILL NEVER BE VERY BIG PER CHAPTER AND
EACH CHAPTER IS GROWING SLOWLY AFTER THE FIRST 50 MEMBERS.

IT’S NOT ABOUT YOU, IT’S ABOUT WHAT
YOUR PUBLIC WILL LEARN FROM IT.

5. What?
A great presentation consists of two important parts:
 well-structured content that empowers the idea that
you're trying to convey

audience's attention on your content.

9. Why?
 US: 21% of US adults read below 5th grade level
(research date: April 28th 2013)
 UK: 20% of UK adults are struggling to read and
write (research date: March 29th 2012)

10. Example – K-means
Machine learning is
way easier than it
looks
Say we wanted to
include a “you
might also like”
section at the
bottom of this post.
How would we go
about that?
K-Means

11. Example – K-means
 Set „K‟ to the number of clusters you want
 Choose „K‟ random points
 Assign each document to its closest point
 Choose „K‟ new points, from the „average‟ of all
documents assigned to each point
 Repeat steps 3-4. Until documents‟ assignments stop
changing.

16. The Big Problem is… YOU.
Or rather, the problem is thinking that what matters in
your presentation is you.
Because unless you're a paid performer – musician,
comedian, motivational speaker – you are not the
reason they came to the conference.
They are sitting in your session because of someone
that matters far more to them than you: themselves.
They are there for their own experiences, and
“watching you present” is not one of those experiences.

17. Conclusion (Guy Kawasaki – Apple)
A PowerPoint presentation should have ten slides,
last no more than twenty minutes and contain no font smaller than
thirty points.
