History of Linux and UNIX! Who gave birth to all modern systems! (Category Engineering)

Interesting. video About the history of operating systems from the channel PRO Hi-Tech, from which it is clearly seen that in the history of unix or gnu linux won not “one feature”, but a combination of ideas + institutions. (people, licenses, standards, communities). From the timelan of events, it is clear that many technologies took part in the course of this story. - 1969: Unix at Bell Labs Simple abstractions under strict constraints (Famous Pipes and Simple Tools That Wait to Enter ) - 1973: rewriting in C Tolerance as a Strategy (portability)

  • 1984: BSD + TCP/IP → Unix becomes native to networks
  • 1988POSIX → General Compatibility Contract for Unix Zoo
  • 1991: Linux (core) The missing puzzle for a free system (core of the GNU ecosystem)
  • 1993+: Debian/*BSD → quality management, releases, packages
  • 2000–2008Darwin/macOS and Android → Unix approach goes to mass platforms (Android and Mac-based)

From all this history, certain conclusions can be drawn, which is useful in product development. - Tolerance = ecosystem driver. Invest in a stable API/ABI and a thin layer of platform specificity

  • File/process/pipe: The power of simple contracts. Small utilities and composition = ancestor of modern microservices and pipelines - Fragmentation treats standards. POSIX was not born out of a love of bureaucracy, but to reduce the cost of portability.
  • Open-source ия Anarchy. Communities survive on governance, CI, release rules, and responsibility for integration - License - architectural solution. It determines who and how can invest, monetize and fork. - "Core" "product". Distribution/SDK/package/delivery policies are often more important than the kernel itself.

For tech leaders, this can land on a set of tips that I think are helpful. Secure the “contract surface”: public API/CLI/formats, SLA, backward compatibility

  • Build a pipeline for accepting contributions: code review → CI → release branches → rollback Divide Owners: kernel/platform vs userland vs distribution/delivery Don't take beautiful narratives at their word: check the dates/causes of decisions - history likes simplification (||Watch the original film and read the docks - make your opinion||)
