Q & A
What was the original purpose of UNIX?
-UNIX was initially created to take computers from the workplace to the home front, aiming to make computing more accessible.
Who were the key figures behind the creation of UNIX?
-Ken Thompson, Dennis Ritchie, and a handful of other young programmers at Bell Labs were the key figures behind UNIX.
What was the state of personal computing when UNIX was first developed?
-When UNIX started in 1969, personal computers did not exist as we know them today. It was the age of minicomputers, which were cheaper than mainframes but still quite expensive.
What is the kernel in the context of UNIX?
-The kernel is the key component of UNIX, serving as the master control program that manages the system's resources and processes.
Why is UNIX significant in the history of computing?
-UNIX is significant because it led the way for many tech pioneers and products, and its design principles influenced the development of modern operating systems.
What is the relationship between UNIX and modern operating systems?
-Many modern operating systems are derived from or compatible with UNIX, including versions of Linux and macOS, which is a variation on UNIX.
What award was UNIX recently given?
-UNIX was recently awarded the prestigious Japanese prize for information and communications.
What was the early development environment like for the UNIX creators?
-The UNIX creators worked in a close-knit group at Bell Labs, often working in the same room, which fostered a sense of community and synergy.
What does Dennis Ritchie envision for the future of computing?
-Dennis Ritchie envisions smaller computers becoming increasingly important, with wearable computers and embedded systems in unexpected places becoming more prevalent.
How has the concept of 'personal computing' evolved since the creation of UNIX?
-The concept of personal computing has evolved from the size of a refrigerator to the smartphones we carry today, with UNIX playing a foundational role in this evolution.
Why might the average user not be aware of UNIX by name?
-The average user might not be aware of UNIX by name because it operates behind the scenes in many systems derived from or compatible with it, making it a seamless part of our digital lives.

Transcripts
you know given the power of smartphones
it's hard to recall a day when a
personal computer meant something the
size of a refrigerator but that was the
reality back when a few guys decided to
shake everything up with UNIX and have
recently awarded a distinguished honor
for their work let's check this out
UNIX isn't exactly a household name but
this early operating system started in
1969 led the way for many tech pioneers
and products to come the inspiration
really was my colleague Ken Thompson who
was really very interested in writing an
operating system and so he started out
and I joined it pretty soon after ken
Thompson Dennis Ritchie and a handful of
others were young programmers at Bell
Labs hoping to take computers from the
work place to the home front
when Eunice was created there was no
personal computers seen instead it was
the this early late 60s early 70s was
the age of the mini computer and this
these were the first computers that as
distinct from the mainframes which were
multi-million dollar machines in the
larger organization many computers were
much cheaper they were some tens of
thousands of dollars say and they were
cheap enough so that they could be
afforded by an individual department in
the company an individual department in
the university and so it was the
beginning of the decentralization of
computing the key component of UNIX is
the kernel or master control program and
some other fancy programming stuff but
while it's not the kind of operating
system most computer users would
understand it's still a seamless part of
our digital lives today average user
probably doesn't know have to know about
UNIX by that name but it's probably
worthwhile being aware that UNIX or
systems derived from it or compatible
with it are pretty ubiquitous a lot of
smartphones run for example versions of
Linux even the cameras on Kindle
runs the software underneath and Mac
os10 for example is essentially a
variation on UNIX recently units was
awarded the prestigious Japanese prize
for information and communications but
Ritchie and his colleagues don't recall
the early days when a sense of community
helped drive them forward the group I
was in was quite close
we often tended to work in the same room
but there was a lot of synergy and lots
of people contributing so as we look to
the future of computing in the 21st
century sometimes it's good to remember
the humble beginnings and where does
Ritchie think we're headed smaller
computers in various ways are going to
continue to be important for example you
know the whole notion of wearable
computers and computers that are
embedded in strange places that you
didn't expect to see them it's going to
become more and more possible Brazil the
eunuchs will go along with that
