It's your well earned time off, an evening or a weekend - yet you are at your keyboard, in the flow, working on your side project, devouring whatever skills and new tech your goal demands, and getting an endorphin kick from seeing results of your efforts along the way. It runs! It does something! And I created it! Not only it's the best feeling ever it also makes you better at your job and a more interesting person; people are drawn to driven, passionate people. But it's not easy to pick something that is really... really worth all that time and focus, is it? Have you started on a website for a local public speaking club and after few months of work felt.. underwhelmed? Or perhaps have you tried to dip your toe into a new technology, like machine learning, and raise your eyebrow at the number of tutorials on how to distinguish tomatoes from grapes or kittens from cars? Yet - we forget there are those nasty problems that we all face as humanity, like climate change, health or equal rights. They do sound monstrous and abstract, but we did our research and split them into bite-size pet projects, actionable and inspiring. We believe - we can all make this world a better place - by following our passion, leveraging technology and having fun! We are two data analysts from Perth, and while every problem does resemble "a machine learning nail" to us, we filled this call to action presentation with ideas ranging from educational visualization to apps and digital communities so everyone feels that there is something for them. Would you chip in?
