Operating systems always have been my favourite computer
related topic, so I know and use many:
- Linux — I've been packaging software in several LinuxDistros, including
Fedora and Ubuntu. I've also put together and distributed custom Linux distributions
for embedded projects, for the OLPC and for the AmigaComputer.
- NetBsd — I've become an official developer with commit access around the time
NetBSD 1.0 came out. I created a custom NetBSD distribution on CD called the
AmigaUnixCompendium. See also OpenSourceDeveloperRole for some of my contributions.
- Sun Solaris — I've been using it since Solaris 7, but a
few years ago I've lost interest in it because of lack of
development. Besides building hundreds of GNU and other
packages to replace almost all of Sun's userland, I successfully
ported the early versions of KDE 1.x and 2.x to Solaris.
- MacOsX — I know this system quite well and have been
using it as a user and developer until mid-2006, when Apple
started taking some steps back from their previous OpenSource
commitment and eventually got rid of the OpenDarwin developers.
- AmigaOs — I've been programming a lot on the Amiga in early
'90s, mostly as a freelance developer. I expecially praised its
unique system and OS architecture, therefore I reused many of its
best ideas in my EmbeddedDeveloperRole projects.
- MicrosoftWindows — I've been developing for Windows with
scarce enthusiasm since Windows 3.1 upto Windows 2000. I'm familiar
with most of the Win32 APIs and concepts, including GUI design
with common controls and MFC, threading, overlapped I/O, events, COM,
ODBC, DAO, VisualBasic, VBA, DirectMedia and DirectDraw.
For new Windows development, today I recommend using portability
layers and framwworks such as Qt, Cygwin, MingW.
