Five ways open source will slow you down (J-Fall)

Software is changing the world - and even other planets. An ever-growing part of software is “open source”. But it hasn’t always been that way! And “doing something open source” is definitely no guarantee for success. There are numerous ways in which you can use open source software and be worse off than if you did not.

Join me in this talk to find out how not to leverage open source software in your organisation and your projects. Find out why reading the documentation may not always be your best bet, or how a workaround may eventually work against you. By investigating 5 ways in which you can fail, we can learn valuable lessons on what to do instead.
