What is Free/Libre and Open Source Software (FLOSS)
Mean?
Free as in No Cost, gratis
Often no or minimal costto download
Community-driven as opposed to company-driven
Companies can charge for support or more services
Free/Libre as in Freedom
Free to use as you wish
Open source: can view the source code
Free to pass it along
Free to modify it

You Already Have Experience with FLOSS
HeikoAL, CC0 Android Open Source Project, CC BY 2.5
Apple iOS: works on Apple hardwareCannot view source code
Google Android: works on many devicesCan view source codeEach company has a flavorCyanogenMod/LineageOS

Pros and Cons of FLOSSAdvantages
● Free cost (often)● Free to view code● Free to modify and
distribute● Save files often
standardized● Skills and concepts
transfer● Community-driven● Agile and adaptive● Always have access (even
after graduation)
Disadvantages● No company support
other companies may fill the gap
● Documentation often sparseUsers create tutorials
● May not help with legacy files
some cross compatibility
● Collaboration and cross-OS compatibility
getting much better
