Sixth Edition Unix, also called Version 6 Unix or just V6, was the first version of the Unixoperating system to see wide release outside Bell Labs. It was released in May 1975 and, like its direct predecessor, targeted the DECPDP-11 family of minicomputers. It was superseded by Version 7 Unix in 1978/1979, although V6 systems remained in regular operation until at least 1985.
AT&T Corporation licensed Version 5 Unix to educational institutions only, but licensed Version 6 also to commercial users for $20,000, and it remained the most widely used version into the 1980s. An enhanced V6 was the basis of the first ever commercially sold Unix version, INTERACTIVE's IS/1. Bell's own PWB/UNIX 1.0 was also based on V6, where earlier (unreleased) versions were based on V4 and V5. Whitesmiths produced and marketed a (binary-compatible) V6 clone under the name Idris.
Wollongong (/ˈwʊləŋɡɒŋ/WUUL-ləng-gong), informally referred to as "The Gong", is a seaside city located in the Illawarra region of New South Wales, Australia. Wollongong lies on the narrow coastal strip between the Illawarra Escarpment and the Pacific Ocean, 82 kilometres (51miles) south of Sydney. Wollongong's Statistical District has a population of 292,190 (2010 est.), making Wollongong the third largest city in New South Wales after Sydney and Newcastle, and the tenth largest city in Australia.
The Wollongong metropolitan area extends from Helensburgh in the north to Shell Cove in the south. It sits within the Wollongong Statistical District, which covers the local authority areas of Wollongong, Shellharbour and Kiama, extending from the town of Helensburgh in the north to Gerroa in the south Geologically, the city is located in the south-eastern part of the Sydney basin, which extends from Newcastle to Nowra.
Wollongong is noted for its heavy industry, its port activity and the quality of its physical setting, occupying a narrow coastal plain between an almost continuous chain of surf beaches and the cliffline of the rainforest-covered Illawarra escarpment. It has two cathedrals, churches of many denominations and the Nan Tien Temple, the largest Buddhist temple in the southern hemisphere. Wollongong has a long history of coalmining and industry. The city attracts many tourists each year, and is a regional centre for the South Coast fishing industry. The University of Wollongong has around 37,000 students and is internationally recognised.
City of Wollongong, a local government area in the Illawarra region of New South Wales, Australia.

"The early days of Unix at Bell Labs" - Brian Kernighan (LCA 2022 Online)
(Brian Kernighan) In barely 50 years, the Unix operating system has gone from a tiny two-person experiment in a New Jersey attic to a multi-billion dollar industry whose products and services are an integral part of the world's computing infrastructure. Along the way, there have been many changes, but a surprisingly large amount is much the same as when it started.
How did this come about? What are the good ideas in Unix that have been preserved and even spread? What are the good ideas that have fallen by the wayside? What are the not so good ideas that have prospered? And what might the future hold?
As someone who was present at the creation (though assuredly not responsible for it), I'll present some humble but correct opinions on these and related topics.

The Hidden Early History of Unix The Forgotten history of early Unix
by Warner Losh
At: FOSDEM 2020
https://video.fosdem.org/2020/Janson/early_unix.webm
The early history of Unix is much richer than is usually presented. There are many hidden gems that are little known and quite interesting to learn about. The dates of many of the "firsts" for Unix accomplishments is much earlier than people think. This well-researched talk explores those gems, firsts and shares many artifacts from the early days of Unix. Many of these artifacts have just come to light in recent years, and change how we view the early history of Unix. Even the oldest of grey beards will learn things they didn't know about Unix from this talk.
Most histories of Unix follow the same old boring plan: talk about Multics, Ken scrounging the pdp-7, moving to the pdp-11, rewriting in C and then ...

Unearthing the History of Unix: Warner Losh
From https://www.bsdcan.org/events/bsdcan_2020/schedule/session/54-unearthing-the-history-of-unix/
We've now had 50 years of Unix under our belts. We use many different technologies in our daily life and may be dimly aware they are from Unix. Much of the early history has been lost due to the passage of time and some of the people that lived through it. Recently, new artifacts have come to life that sheds more light on the early days of Unix. These artifacts are showing a more complex and nuanced history than the typical ones told to date. This talk will explore these new finds, as well as many that are hiding in plain sight. From the early PDP-7 unix, to later innovations like networking and SMP, there are surprises at every turn.

Most histories of Unix follow the same old boring plan: talk about Multics, Ken scrounging the pdp-7, moving to the pdp-11, rewriting in C and then the explosion that happened with V6 and V7 before jumping into the Unix wars between AT&T and BSD followed by something about Linux (either pro or con depending on the speaker's politics). We've all seen it, and many can predict which "classic" pictures will be used, the points that will be made, and the arcs drawn.
This talk is nothing like that. It brings all the early years of Unix to life in a unique way. The early years of Unix were surprising rich. The author will use original sources to take you on a tour of many of the firsts in Unix and explore the community ties key to Unix's early success. Many of today's fads, like microkernels, hypervisors, multiprocessing and user mode execution actually happened early on in Unix's history, long they were today's fads. "What's old is new again" has never been so apt. You'll be surprised to learn how early each of these things happened. Come see the secret history of Unix as it played out both in obscure business units of AT&T and in the world wide users groups who banded together to support each other when AT&T wouldn't. You'll see footage of early machines as well as the first real Unix application: space travel (newly rediscovered and restored by the TUHS group). See first hand the machines, programs, newsletters and documentation that together weave a rich tale of innovation, community and working within constraints. Learn how today's open source movement owes a debt to these early communities and how they paved the way for Unix to become the open and ubiquitous system it is today and helped sow the seeds for the communities of today.

EFD – information as how early a fault can be detected. They consider EFD a kind of simple indicator of defect severity, and this kind of information is easy to get from a black-box testing perspective. Their strategy is based on the idea that a test case that detects a failure earlier in its execution should have a higher fault-detection capability than those that detect failures at a later stage of their executions.
The Siemens Suite of Programs - Ten researchers at Siemens manually created faulty versions for each of the 7 base programs, aiming at introducing faults as realistic as possible.
SPACE - was developed by the European Space Agency and the faults were real faults discovered during the development of the software.
GREP - is a Unix/Linux utility. Because comprehensive test suites were not available, they used the category-partition method and a TSL tool to construct a suite of black-box test cases that exercise each parameter, special effect and erroneous condition of the base programs.
SED - is another Unix/Linux utility. The test suite was constructed using an approach similar to that of GREP.
