NetBSD
Occasionally I play with the NetBSD operating system, a system derived from 4.4BSD and Unix. I'm a member of the NetBSD Foundation and I have commit access to the NetBSD source code.
Writing
I wrote some papers and blog posts on NetBSD. Here they are:
- Transitioning from a.out to ELF on NetBSD, about the change of binary formats on the i386 platform between NetBSD 1.4.3 and NetBSD 1.5.*;
- NetBSD/i386 from 1.0 to present, where we install 1.0 on a virtual machine and upgrade it just using the compiler to the latest version.
- Forking NetBSD, where we convert a NetBSD 1.1 system to OpenBSD 2.0.
- Installing NetBSD 0.8 on Bochs, where we install an early version on an emulator.
