Hi, I think it would be much better to implement accessibillity for visualy impared people when building an os, than having to find ways to make that possible when everything is built and running. Nvda is a good opensource screenreader for windows The only big problem is, it heavily depends on msaa and iaccessible which will not be included in reactos i suppose. So: what would be the way to make this os accessible for the blind? I am not a programmer at all so maybe i say stupid things. The most simple way i could think of is, creating a textmode environment. In this case i do not mean just a command prompt, like dos, but the full functions but without graphical interface(like the browser browsh, www.brow.sh) can do using a headless-firefox to open pages without needing anny graphical interface(in monochrome mode it displays just text, but is able to stream youtube/everything firefox can handle). If something like that can be created in reactos, the only thing needed is to make the windows binaries of brltty work and much of the accessibility would be ready to use, as long as every graphic element is banned from the screen otherwise blrtty will display just lines with ??????????????? on the braille display. I am curious to know if some things can be done to make reactos accesible for the blind. best regards, Dick

DbgCom release note.

by Neo Love

Greetings fellow developers... After a rather long hiatus (I actually came close to death), I went back to the DbgCom source and merged some improvements that are now in the RosIDE I'm working on. Most notably a Preferences settings dialog, but also some improved performance in the message list painting, and various bug fixes. The first time you run DbgCom, be sure to execute the Preferences dialog, and Ok the settings, so they get stored in the registry. I will make the source dependencies available shortly, they just need to be cleaned up a bit, since there is currently some hackery in there that I don't want to publish. I'll notify you on the ROSBE-100 page. You'll find DbgCom here: https://jira.reactos.org/browse/ROSBE-100 Well, that's it I guess. Best Regards / Love

Re: [ros-dev] [ros-diffs] 03/04: [KERNEL32] Directly use UnhandledExceptionFilter in BaseProcessStartup

by Alex Ionescu

Same here! This will break things. We should not be overriding the proper handling of the exception filters.

Re: [ros-dev] [ros-diffs] 02/04: [KERNEL32] Use the default UnhandledExceptionFilter in BaseThreadStartup. This should allow unhandled exceptions in a thread to trigger our crash reporter, instead of killing the process directly.

by Alex Ionescu

Uhh, this change is not correct. It overrides the proper handling of exception filtering -- please revert.

Upcoming Google Summer of Code Mentor Summit

by Colin Finck

Hi all, As announced, I'll be travelling to California this Thursday to attend the Google Summer of Code Mentor Summit from Friday to Sunday. I'll be using this opportunity to spread the word about ReactOS, our experiences with GSoC, and learning from other projects' experiences. I'm especially interested to hear how others are acquiring talented students and managing their list of task ideas over the year. Let's hope this will help us to get more than 1 student next year and efficiently collect a list of GSoC ideas continuously instead of preparing it shortly before the deadline ;) Is there anything else you want me to talk about during the summit? Cheers, Colin

Add InitializeProcThreadAttributeList function

by Biswapriyo Nath

I found that this function `InitializeProcThreadAttributeList()` is added with GetProcAddress but not with the real function. I can provide the real function from Windows 10. The function hasn't any imported function, just conatins some arithmatic operations. I don't know how to contribute and not familiar with ReactOS repo. So, I can only provide a c file.

Re: [ros-dev] [ros-diffs] 01/01: [SERVICES] Fix timeout when a service is stopped

by Pierre Schweitzer

Hey Eric, What's the purpose of that "Sleep(2000);"? Is it a debug leftover?
