I've spent some time recently upgrading my old workhorse a Sun Ultra 2, the last real Sun machine made in my opinion ;) It might not be as fast as the new fancy servers but i really don't know what i would do with all the CPU-cycles for things like SSH, Apache and mail. And after all these years we have grown emotionally attached. Now things should keep running smooth well into the next decade. Getting ZFS, DTrace and Zones on my outside server is also nice.
I've been using Unix, mainly Solaris for over 15 years. While Solaris was open I tried to be part of the community with this blog and by filing bugs and debugging.
During the days I work with standardization and implementation of the Unix platform at a large company. This involves design and implementation of Solaris and everything around it including security, performance, storage, virtualization and development.
I also work as a consultant part time and can be contacted at henrik (at) gigamega.se.
