UNIX 誕生
1969 年，Ken Thompson 和 Dennis Ritchie 開始開發 UNIX。一開始，UNIX 是使用組合語言撰寫的，不過一段時間之後它就被用 Ritchie 所發明的高階語言 C 重寫。
C++ 被創造出來
1979 年，Bjarne Stroustrup 開始開發「包含型別的 C (C with classes)」，這之後會變成 C++ 語言。Stroustrup 認為，它是當時唯一讓人能寫出既高效率又簡潔的程式的語言。
Bjarne Stroustrup自由軟體的開始
1984 年，Richard Stallman 開始開發 GNU，一個基於 Unix 的完全自由的作業系統——Unix 當時是專有軟體。GNU 是 GNU is Not Unix 的遞迴縮寫。
Linux 核心
在 1991 年，Linus Torvalds 創立了基於 MINIX 的 Linux 核心。（MINUX 是由 Andrew Tanenbaum 所寫的 Unix 版本。）Linux 的出現讓自由軟體的歷史出現革命性的進展，讓自由軟體變得更多人使用。請見 Linux 核心開發 25 週年時的宣傳圖.
最初的發行版誕生
1993 年，最初的自由發行版開始出現，基於 GNU 及 Linux。一個 GNU/Linux 發行版一般由 Linux 核心、GNU 工具和函式庫，以及一大群應用程式所組成。
KDE 發表
1996 年，Matthias Ettrich 宣佈了「酷桌面環境」 "Kool Desktop Environment" (KDE) 的創立，它是一個 Unix 系統用的圖形介面，使用 Qt 與 C++ 製作並為普通使用者所設計。"KDE" 這個名字是致敬當時專有的圖形環境 CDE。在此可以閱讀 KDE 專案最初的發表。
