Google Summer of Code 2022 - Call for contributors

We are proud to announce that ReactOS has been accepted into the 2022 Google Summer of Code program. The GSOC program is a great opportunity for a fresh contributors looking to join the Open Source and Free Software movement. This year we are looking for new contributors who want to enhance skills in kernel development and NT architecture. Our team consists of skilled mentors who are going to guide eager students with ReactOS architecture and development practices.

ReactOS will be on Chemnitz Linux Days 2022 (Online event)

ReactOS will participate with an own booth on CLT 2022. It will be held on this Saturday and Sunday. Starts at 9:30 CET and ends at ~18:00 CET on both days. The whole thing will be held online and to make you at least feel a bit like you are there in real they once more use the WorkAdventure platform.

In this release, improvements range from FreeLoader fixes, Shell features, kernel fixes, NetKVM VirtIO bringup, further work on the Xbox port and support for NEC PC-9800. Note that it took us over a year to get this release in shape and fix regressions.

Newsletter 101 - July 2021 news

Hello ReactOS followers! This report covers changes in the project during February-July 2021. And we definitely have some things to highlight! amd64 build is getting more stable Timo Kreuzer (tkreuzer) worked hard on various parts of the kernel and HAL, fixing issues here and there. Structured Exception Handling (SEH) support for the amd64 architecture was finished, various bugs around the kernel are fixed. A major issue with interrupt handling in HAL was also fixed in May, which finally allowed a semi-stable boot in a virtual environment.

Welcome GSoC 2021 Students!

Another year, another round of Google Summer of Code! The ReactOS Project is participating in Google Summer of Code 2021 and welcomes the selected students. He Yang is a successful student from GSoC 2020, who is going to continue his dive into user-mode ReactOS this year by working on iernonce.dll. That library is responsible for RunOnceEx, a prominent Windows feature to run multiple commands once after a system reboot. Implementing that feature will benefit software depending on it.

Newsletter 100 - January 2021 news

Hello ReactOS followers! This is an attempt to re-instate the Newsletter, which informed you about recent developments. The previous Newsletter 99 was in 2013! This month we were mostly focused on the kernel work, merging pull requests and fixing regressions. Memory manager and Common cache work Being in development for almost six month, this work by Jérôme Gardou finally landed in the master branch. This change refactors many aspects of the Section Objects feature in NT-compatible kernel, making it more compatible with Windows.

ReactOS in 2020

Despite all the turbulence, it has been quite a productive year for ReactOS. Many bugs and instabilities were resolved, many more have been introduced. This year we hired two kernel developers full-time, this happened for the first time in the project’s history. The post highlights some of the changes which may be interesting to the community. Shell changes Shell hasn’t seen much attention recently, due to most of the work being concentrated in the kernel, but there are still some useful fixes and feature implementations:

Jérôme Gardou hired full-time to work on the memory manager

I proudly announce that ReactOS Deutschland e.V. has hired Jérôme Gardou to work full-time on the ReactOS kernel’s memory manager for the next 3 months. Jérôme is a ReactOS veteran who has been contributing to the project since 2009. He has deep expertise into nearly all parts of ReactOS, ranging from various user-mode components (mostly related to low-level graphics) over their kernel-mode counterparts and down to bare-metal components like the kernel memory manager.

Porting Syzkaller to ReactOS Final Evaluation - GSoC 2020

Hello everyone, I am Suraj K Suresh, the one working on the GSoC project of “Porting Syzkaller to ReactOS”. It’s been 3 whole months since GSoC has begun and this is the last evaluation period. During the last 3 months, I worked on various parts of Syzkaller and getting them up and running on ReactOS and Windows with the help of my Mentors. This blog post will be a wrap-up post of the GSoC project.
