Gelagat & Ragam Orang Melayu
Saya sudah lama ingin bacha buku ini. Akhirnya pada 27 Ogos 2025 yang lalu, hasrat terchapai. Ianya ditulis oleh Frank Swettenham (1850-1946) di mana tajuk asalnya adalah 'Malay Sketches' yang diterbitkan pada 1895 di London. Beliau tiba di Singapura pada Januari 1871. Beliau mengambil peperiksaan berkaitan Bahasa Melayu pada Julai 1872 bagi memahami kehidupan orang Melayu ketika tiba di Tanah Melayu. Pada Disember 1874, beliau sebagai Penolong Residen Perak dan menjadi Residen Perak pada 1889.

Babbage's Diffrence Engine
The Difference Engine was a groundbreaking invention by Charles Babbage in the early 19th century, often considered a major step toward modern computing.
What Is the Difference Engine?
It’s a mechanical calculator designed to compute polynomial functions using the method of finite differences—hence the name.
The machine could automatically generate mathematical tables, which were crucial for navigation, engineering, and astronomy at the time.
Key Features:
Invented: Around 1822, Babbage presented it to the Royal Astronomical Society.
Powered by: A hand crank, with values represented by toothed wheels marked with decimal numbers.
Precision: Aimed to produce results with up to 20–30 digits, far beyond the usual 6-digit calculations of the era.
Historical Impact:
The British government funded the project, hoping it would reduce errors in printed tables, which had cost them millions and even led ships astray.
Although the original engine was never completed in Babbage’s lifetime, a working version—Difference Engine No. 2—was built by the Science Museum in London in 2002 using his original plans.
Legacy:
Babbage’s Difference Engine laid the foundation for his later invention, the Analytical Engine, which introduced concepts like memory, loops, and conditional branching—core ideas in modern computing.
Want to dive deeper into how it compares to today’s computers or explore Ada Lovelace’s role in this story? I’d love to take you there.
