16. Back in 1999
Sun Microsystems CEO Scott McNealy said
"Linux is like Windows: it's too fat for the client, for
the appliance ... it's not scalable for the server ...
Now why in the world would anybody ever write
another cheque to Microsoft? I don't know. But
why would you do Linux either? That's the wrong
answer." 1)

17. Back in 1999
Back then UNIX powered around 50% of world's
supercomputer market 1)
Five of ten the most powerful supercomputers ran
UNIX 1)
SUN Microsystems was 69th biggest company in
the USA– Value $54B2)

18. How About Now?
UNIX powers 2% of top 500 supercomputers, and
Windows 1% 1)
The rest – 97% – is powered by Linux 1)
SUN was bought by Oracle with $5.6B in 2009 3)
That's like 10% of the value in 1999

40. Perspective Through
Numbers
Surveys have found that developers expend on
average 11 hours a week on open source efforts (a
median of 7 hours), more than 25% of a standard
work week4)
This is 0.29 FTE (full time equivalent)
Thus 3.4 part time open source developers lumped
together work as much as one full time paid developer

41. Perspective Through Drupal
Drupal Community has over 1.167M users and
over 37,000 developers5)
The estimate of full time equivalent of Drupal
community development is thus
37,000 x 0.29 = 10 370
5) http://en.wikipedia.org/wiki/Drupal
43. Perspective of Drupal 8
Drupal 8 has been developed by more than
3,200 core contributors 5)
The estimate of full time equivalent of Drupal 8
community development is thus
3,200 x 0.29 = 928
