1 like436 views
The document discusses the Go programming language, highlighting its simplicity and efficiency compared to other languages such as C, C++, and Python. It provides a historical context of Go's development, mentioning key figures and milestones in its timeline from design to open source. Additionally, it emphasizes Go's unique blend of high-level and low-level language features, asserting its position as a modern programming solution.

- 18. Quote "Go seems as perfectly in between C and Python: it can be seen as a modernized C, or like a super-optimized Python." -- Enrico Franchi Go with the Flow Nicola Larosa 18/35

- 20. Lineage "In 1960, language experts from America and Europe teamed up to create Algol 60. In 1970, the Algol tree split into the C and the Pascal branch. ~40 years later, the two branches join again in Go. Let's see if Go can enjoy an equally long run as its predecessors!" -- Robert Griesemer, GopherCon 2015 Go with the Flow Nicola Larosa 20/35
