ReactiveUI - An advanced, composable, functional reactive model-view-viewmodel framework for all

•    CSharp

---

ReactiveUI is a composable, cross-platform model-view-viewmodel framework for all .NET platforms that is inspired by functional reactive programming which is a paradigm that allows you to abstract mutable state away from your user interfaces and express the idea around a feature in one readable place and improve the testability of your application.That's reactive programming: changes propagate throughout a system automatically. Welcome to the peanut butter and jelly of programming paradigms. For further information please watch the this video from the Xamarin Evolve conference - Why You Should Be Building Better Mobile Apps with Reactive Programming by Michael Stonis.

plots2 - PublicLab

•    Ruby

The content management system for the Public Lab research community, the plots2 web application is a combination of a group research blog of what we call "research notes" and a wiki. Read more about the data model here. It features a Bootstrap-based UI and a variety of community and attribution features that help the Public Lab community collaborate on environmental technology design and documentation, as well as community organizing. Originally a Drupal site, it was rewritten in 2012 in Ruby on Rails and has since extended but not entirely replaced the legacy Drupal data model and database design.

Lumos - 😴 Smart Lighting for Better Sleep

•    Python

---

There are plenty of smart lighting systems out there that let you change light colors and dim with just your smartphone (or even your voice), but this Open Source lamp called Lumos is a smart lighting system that works to benefit your health. Lumos mimics the natural light of the sun as it passes overhead each day, generating bright blue light in the morning and warmer amber light in the evening. Decades of research from Harvard Medical School , NASA , and leading institutions around the world have revealed a great deal of information about how light impacts and regulates our health. They explain that blue light aids in the production of cortisol, which is important to give the human body energy in the morning, and red light aids in the production of sleep-inducing melatonin. Almost 20% of the world's population is sleep deprived & possibly spends more than 8 hours a day under an unnatural light, which can throw off the body’s internal clock and prevent it from performing at optimum levels.
