Green Software: Rethinking Software Development to Save Our Planet

Did you know that software applications' greenhouse gas emissions surpassed those of the aviation industry? As our reliance on technology continues to grow worldwide, so does the environmental impact of software applications.
But as software developers, we have the power to make a positive impact in the fight against climate change.
This session revisits established development practices, providing practical guidelines for developers and architects to measure and reduce software applications' environmental footprints.
The focus is on practices requiring minimal development effort while still providing the maximum savings in carbon emissions. At the same time, most of these practices will help reduce the costs of your cloud applications because they minimize the consumed resources (CPU, memory, storage, network).
It is assumed you are involved in building software applications and aspire to help prevent climate change.

How to Improve the Quality of Your Application (I Wish I’d Known This Earlier!)

Do your customers keep complaining about bugs in your software application? Does it take you too long to fix bugs and implement new features? If yes, then you may have issues with the quality of your application. This session provides practical advice on how you can improve the quality of your software application. The speaker shares with you all the lessons he learned while working as a software engineer for a big, complex enterprise application, discussing which techniques worked and which ones failed and providing actual examples and metrics from that application. It’s assumed that you have already experienced the struggle of maintaining a defective software application and that you aspire to building software of top quality.
