ReactOS Hackfests in 2026
The ReactOS project has held hackfests where we met up to develop the operating system. When core team members and contributors hold these multiday hackfests, we are able to progress not just the foundational code of the operating system, but also our project guidelines and rules. This year there were two hackfests. The first was during and after Chemnitzer Linux-Tage (CLT), from March 28th to April 4th. The second was in Orlando, Florida, from October 9th to October 19th. -

Let’s take a brief look at some of the high and low points throughout our history. -
An initial investigation into WDDM on ReactOS
The history of ReactOS spans a wider range than the lives of many of the people who work on it today. Incredible individuals have come and gone from the project with vastly different goals for what they want to see developed. In recent years, better hardware support has emerged as one of those goals. As ReactOS gazes towards the world of Vista and beyond, a few questions about how hardware works emerge. -
