Operating System Source Code Secrets Volume 1: The Basic Kernel
by William Frederick Jolitz (Origins of 386BSD
William and Lynne Jolitz were inspired to work on 386BSD by the experience with
Symmetric Computer Systems (see "William Jolitz and Symmetric Computer Systems") and the uses of BSD on a ubiquitous platform it inspired.

Summary: Where is 386BSD Now?
Perhaps the discussion of some of these issues might have seemed difficult or incomplete, but we found each item to be of tremendous importance in understanding the practice of a port to the 386 architecture. Unlike Berkeley UNIX ports to other systems, we found that we had to bend over backwards d ...

Designing the Software Specification
Prior to leading the 386BSD project, Bill was the founder and CEO of Symmetric Computer Systems, a BSD-based workstation and networking products manufacturer. He was the principal developer of 2.8 and 2.9 BSD and the chief architect of National Semiconductor's GENIX project, the first virtual memo ...

Systemverwaltung durch Tabellen
8/91 UNIX Magazin, Germany: Systemverwaltung durch Tabellen, William F. (Bill) Jolitz and Conflicts in Priorities
These basic priorities inherently conflict. For example, BSD systems have basic incompatibilities with the AT&T System 5 UNIX systems, because each project has firm interests and no compelling need to cooperate. As such, perfect compatibility is impossible to achieve given our project focus. The ...

Getting Started: References, Equipment, and Software
Most software ports begin with the naive assumption that the UNIX kernel is merely a C program with a handful of functions, supporting other utility C programs on demand. While in essence this is true, in practice this is a vast oversimplification. Nevertheless, in the tradition of great projects, ...

The Definition of the 386BSD Specification
At first glance, the choice of the 386 microprocessor and ISA system architecture appears to define the operating system's machine-dependent requirements. For example, on the original 8088 PC to the present, MS-DOS would use the software interrupt INT $XX instruction to dispatch through the interru ...

Then and Now
This was our first article on 386BSD, appearing at the end of 1990.As the article series attmped to duplicate the methodology of our project, this article coincides with theoriginal software specification that we wrote and had solicited on the INTERNET months prior to the start of system coding. ...

Lynne Jolitz and copyright
Lynne Jolitz, writer and technologist, was not only the co-creator of the
386BSD
operating system - the
first open source Berkeley Unix
release for the X86 platform - she was also a leader in the
fight for the
Berkeley open source copyright.
Since her days as an executive at
Symmetric Computer Systems,
one of the
first BSD UNIX startups,
Lynne has always
sung the praises of the great university work called the Berkeley Software Distribution.
Of course, Berkeley is also Lynne's alma-mater, and its influence on academic achievement
and battles for academic freedom is also strongly felt. Her ringing endorsement of
the
Berkeley open source copyright
and her own corporate experience,
Copyright, Copyleft, and Competitive Advantage
appeared in Dr. Dobbs
Journal as part of
PORTING UNIX TO THE 386: LANGUAGE TOOLS CROSS SUPPORT
a decade before the legal community found it fashionable dinner conversation.

William Frederick (Bill) Jolitz was born in Michigan. He grew up in the midwest, east, and then
finally western United States, as the family followed the aerospace business around the country.
William Jolitz attended Lynbrook High School in San Jose, California, and worked at NASA Ames Research
Center while a high school and college student. While attending the University of California, Berkeley
he was part of the Homebrew Computer Club .
He
graduated from the University of California, Berkeley with a degree in Computer Science and has been
a member of the Berkeley Engineering Society.
Lynne Greer Jolitz , formerly Lynne Greer Messner, was born in Fremont, California.
Lynne received a Bloss Scholarship for outstanding achievement
to attend Berkeley upon graduation from Merced High School.
Lynne remembers one of her fond memories of high school - appearing in the local high
school musical:
A student of natural history and anthropology, Lynne made a shift into "hard science"
and following high school went to the University of California at Berkeley in the Physics department.
Surrounded by Nobel prize winners, Lynne Jolitz graduated from Berkeley and applied her skills
in business and technology pursuits, eventually finding a home in understanding how
technology and people fit together.
William and Lynne Jolitz were inspired to work on 386BSD by the experience with
Symmetric Computer Systems (see "William Jolitz and Symmetric Computer Systems") and the uses of BSD on a ubiquitous platform it inspired.
BSD needed to jump to the 386. According to the website (see the_past() - name_origin):
Origin of the 386BSD name was with the first 16Mhz release by Intel, starting the
architecture family. Most software vendors call all in this family, which includes
strangely enough the AMD 64-bit version, the "386" architecture.
*
There has only been one architecture, no matter how refined or redefined by others
to suit peculiar needs.
*
386BSD is BSD on the 386.
In looking for the good, the simplest spanning name to grab mindshare was chosen.
Just as Windows and UNIX have been named the same all along, saw no need in any
different name. Others, in attempting to look for the bad, chose to narrowly view the name as applying to a specific chip to force an
unearned claim of obsolescence. Inside all of them, the machine dependant names are all "386".
Benjamin Torsten Jolitz is into robotics, science fiction, computers,
and telescopes. Ben rebuilt a 30 year old telescope and hand-ground
mirror from his Grandpa (see "Where Ben's Scope came from ...
") and used it to win a second place in earth / space
science at the 2004 Synopsys science fair with a study of collimation
techniques (see "Benjamin Jolitz Wins Science Fair Award
"). Ben likes hanging around the SJAA ATM guys talking shop
and grinding
his own mirror. Ben also likes showing off his scope at star parties - especially
to pretty girls who like science (see "Tech Trek 2003 Star Party").
Ben is an accomplished Berkeley Unix 386BSD system administrator, and
also handles video production technical and support issues. Ben collaborates
on short subject films and participates in film festivals - his
latest work "Bots" (see "Jolitz Family Video - Bots" for web video and "Bots DVD by Benjamin Jolitz and Rebecca Jolitz" for a DVD) is a comedic exploration
of the roles of robots in popular films. Ben says BSD is technically
better than Linux, but thinks conflicting shared libraries, incompatible threading,
and inconsistent program development makes BSD "run like crap". He
thinks the Linux community is much more together because the BSD
side is "too old, full of it, and doesn't want to learn python".
Rebecca Dawn Jolitz loved science fiction, filmmaking, and
astronomy from her earliest years. At star parties for the public, Rebecca showed
people the planets and stars (her favorite double is Alberio, the
blue and gold "Cal star") with her Celestron C-5
telescope. Rebecca had even taken her telescope to Stanford Tech Trek (see "Rebecca Jolitz Demos Telescope Techniques at Stanford Tech Trek") to
demonstrate how SCT telescopes work, even though she wants to major
in astrophysics at Cal. She went to Cal Day every year, especially
to see Professor Shugart do his "Fun with Physics" lecture.
Rebecca accomplished much as a video editor and producer,
and created movies for film festivals (see "Rebecca Jolitz Debuts Movie in Kids Film Fest"). She currently works on a
research project on video serving for educational use using
a modern version of Berkeley Unix 386BSD (Jolix).
Rebecca spent much of her youth on basketball, needlework,
playing the guitar, and collecting
Breyer horses.
Archive of published works of various kinds by Jolitz. An essential part of the Jolitz Heritage has been widespread publication, commentary, and opinion. Literally hundreds of these items that are slowly being assembled into this site. Check back soon both for missing older items and new ones as well!
William Leonard (Bill) Jolitz, a native of Duluth Minnesota, made the transition from
a boy from the "wrong side of the track" to esteemed chemical engineer, inventor, and aerospace
engineer in Silicon Valley. Like so many other men of the time, he was
recruited and served in the European theater of World War II, most notably at the
Battle of the Bulge. After returning from the war and completing his engineering studies
at the University of Minnesota, he wisely convinced Norma I. Westman, a
Duluth Swedish beauty, to marry him. They had four children (Brenda, Marsha (dec.),
William Frederick, and Kimberly), and remained happily married until his death in 1994.
