My Position
Free Software enables mass uptake, freedom to innovate.
Using Free Software for your business gives you control and
flexibility; using Free Software in your products gives your
customers control and flexibility.

Agenda
 Business – Using Free Software to manage your daily tasks
 EDA – Using Free Software to design Hardware
 Embedded Development with Free Software Toolchains
 Free Software Philosophy
 Q&A
11
Examples of Innovation Through Freedom
 IBM PC
 Original PC included schematics and BIOS sources
 ISA slot encouraged third party options
 Giving users control and flexibility increased popularity
 LAMP Stack – Linux, Apache, MySQL, Python
 Basis for many business back-ends and web sites
 Anyone can offer support, or contribute changes
 Quake III
 License allowed for third party levels and mods
 Kept game 'fresh and relevent' long after the initial release
 GNU Toolchain
 Many contributors, many users = ubiquitous
 Nokia, Android, iPhone
 Based on Free Software, value add is the extras
12
What does “Free Software” mean?
 The freedom to run the program, for any purpose.
 The freedom to study how the program works, and change it
to make it do what you wish.
 The freedom to redistribute copies so you can help your
neighbor.
 The freedom to distribute copies of your modified versions to
others. By doing this you can give the whole community a
chance to benefit from your changes.

Free Software: Philosophy
Free Software isn't a “religion”. It is a set of beliefs that can be leveraged to
add value anywhere in the business plan, from internal operations to customer
experience

Sharing
Community
Support
License
Licensing
Philosophy: Sharing

Each participant helps the project grow




Each participant must share responsibility and control



25
Adding features
Providing feedback
Testing
Can't “own” the software design
Must work together
Expected to help fix bugs you find
Philosophy: Community

Business demonstrates care and trust in customers




Growing pains are public



26
Gives customer freedom to innovate
Treats customers like partners, not minions
Lets customers share in the development process
Design defects are easier to spot by customers
“Release early, release often” means more bugs may
escape to the public
Must be willing to accept constructive critisicm from the
community!
Philosophy: Support

Free Software enables third-party support options



No central “author” to be a know-all



Public contributions are best understood by their
individual authors
Public forums and B2B help common
Value in support, customization, accessories

27
Customers can pass sources along to others to help with
support
Customers can support themselves
Focus on your core competencies, let others provide
niche solutions that you'd otherwise be unable or
unwilling to supply.
Philosophy: License


28
The Free Software license gives freedoms to the users,
but prevents users from denying those freedoms to others
“Freedom for the software”
No worries about “unauthorized copying” or piracy – it
just doesn't exist with Free Software
Community-driven extensions and enhancements are
allowed, if not encouraged, by the license
“Security by obscurity” is no longer an option
No concept of “Software IP” - there's no intrinsic value in
something that can be trivially copied for no cost.
Philosophy: Licensing

Licensing models are simplified




Software License is no longer a revenue stream




29
No activation keys
No per-seat fees
No license dongles
Value, and thus revenue, is in the people behind the
software – support packages, customization, training, etc.
Customers can buy support packages that meet their
needs, not their employee count.
Attracts smaller customers
Allows for unlimited “try before you buy”
