Syllable, AtheOS AtheOS is a modern, free (GPLed) Operating System written from scratch in C++. A big chunk of the OS is POSIX compliant, supports multiprocessing and it is GUI-oriented (fully OOP). Today we are hosting an interesting interview with the AtheOS creator, Kurt Skauen. Kurt is talking about his views on binary compatibility in future versions, multithreading and the future of his OS in general.

Re: multithreading

i indeed too think that forcing to use a thread per window is not a good thing. on the other hand it can be quite difficult to program a thread per window in an other os, but that would normally not be necessary. i would rather use threads for "lengthy operations". also the default behaviour of bcontrols to send a message when invoked without containing the new value made some of my porgramming hard. by the time i would get that message and read the value from the bcontrol that sent it, the control could have been changed by another thread and in my application this wasn't what i needed. what i do like about the beos is its scheduler with realtime and non-realtime scheduling. also system_time() is very accurate, much more accurate than most operating systems provide. it would not be that usefull if there weren't also snooze_until(), which is super-accurate. i think this is because the kernel dynamically programs the pc clock chip? anyhow, it's not all bad, but without updates it's not going anywhere either. they could switch to gcc3 breaking binary compatibility and at the same time rewrite the interface kit to support single threaded applications, but that is not going to happen. -- martijn
