William Jolitz and Berkeley in the 70's/80's
William Frederick Jolitz attended the University of California, Berkeley during a period of great change and opportunity.
While still staying involved with NASA and "Silicon Valley" to the south (often by motorcycle, same day),
Cal's environment of science, engineering and technology was very di ...

Science at Cal in the 70's - Astronomy, Physics and Electrical Engineering
Classes in Physics were competitive due to pre-med and engineering students viewing it as a
"battle of attrition" rather than first steps in a career. Hands-on laboratory experience, while
assigned, was deemphasized, with the primary focus the discovery of potential theoretical
candidates to ref ...

Mid 1970's where the action was
C programs, then unusual, were cross compiled on the NASA ASRS PDP-11 Unix system located
in the Life Sciences, and downloaded over the SYSTRAN/ADTRAN RS-232 serial network
strung around Ames in pre-networking days. Discovered UNIX, the Arpa net, and had an
account on mit (wfj@mit-ai, a nice PDP ...

Introduction to UNIX
When researching text to speech, I attempted to obtain a copy of a program done by
Doug McIlroy at Bell Labs Murray Hill. In talking with him on the phone, he said
"Sure, send a check for $20,000". Shocked, I asked why, "Comes with a PDP-11 operating
system, which lets you compile and run it". T ...

Lynne Jolitz Sifts Technology
An early BSD user of Version 6 Unix and 2.8BSD on PDP-11's, she found early systems a
mixture of good and bad. "Good" needed explaining, but "bad" needed replacement.
Unless you got "bad" out really fast, it took on a life of its own, with many
attempting to find a way to justify it as "good". S ...

Sensory Aid Architecture
 DEC LSI-11
Contributions of equipment, borrowing, and ingenuity got together a DEC LSI-11 as the
"microcontroller", a Interrupt Priority Level Management
In the PC architecture, there is a separate interrupt level per device interrupt. These are more levels than traditional UNIX wants or needs. Instead, UNIX groups different classes of devices into interrupt priority levels that can be disabled and enabled as a group (disks, terminals, network). T ...

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.
