What are the things that a programmer must know (obviously besides programming languages)?
The word “computer” was first recorded as being used in 1613 in a book called The Yong Mans Gleanings by English writer Richard Braithwaite to describe a human who performed calculations or computations. In the book he said, “I haue read the truest computer of Times, and the best Arithmetician that euer breathed, and he reduceth thy dayes into a short number.” (The spelling mistakes were all deliberate BTW, it was a simpler time back then).
1. The first “pre-computers” were powered by steam
In 1801, a French weaver and merchant, Joseph Marie Jacquard, invented a power loom that could base the design of a fabric upon punched wooden cards.

Fast forward to the 1830s, and the world marvelled at a device large as a house and powered by six steam engines. It was invented by Charles Babbage, the father of computing – and he called it the Analytic Engine.

It is the reader that makes the Analytic Engine innovative. Using the card-reading technology of the Jacquard loom, three different punched cards were used: Operation cards, number cards and variable cards.
Babbage sadly never managed to build a working version, because of ongoing conflicts with his chief engineer. It seems even back then, CEOs and devs didn’t get a long.
2. The first computer programmer was a woman
In 1843, Ada Lovelace, a British mathematician, published an English translation of an Analytical Engine article written by Luigi Menabrea, an Italian engineer. To her translation, she added her own extensive notes.

In one of her notes, she described an algorithm for the Analytical Engine to compute Bernoulli numbers. Since the algorithm was considered to be the first specifically written for implementation on a computer, she has been cited as the first computer programmer.
Did Lovelace go onto a life of Ted Talks (or whatever the Victorian equivalent was)? Sadly not, she died at the age of 36, but her legacy thankfully lives on.
3. The first computer “bug” was named after a real bug
While the term ‘bug’ in the meaning of technical error was first coined by Thomas Edison in 1878, it took another 6o years for someone else to popularize the term.

In 1947, Grace Hopper, an admiral in the US Navy, recorded the first computer ‘bug’ in her log book as she was working on a Mark II computer.
A moth was discovered stuck in a relay and thereby hindering the operation. Before it was recorded on her note, the moth had been ‘debugged’ from the system.
On her note, she wrote, “First actual case of bug being found.”
4. The first digital computer game never made any money
What is considered as the forefather of today’s action video games and the first digital computer game wasn’t particularly successful.
What is considered as the forefather of today’s action video games and the first digital computer game wasn’t particularly successful.
In 1962, a computer programmer from Massachusetts Institute of Technology (MIT), Steve Russell, and his team took 200 man-hours to create the first version of Spacewar.
Using the front-panel test switches, the game allowed two players to take control of two tiny spaceships. It became your mission to destroy your opponent’s spaceship before it destroyed you.
In addition to avoiding your opponent’s shot, you also had to avoid the small white dot at the centre of the screen, which represents a star. If you bumped into it, boom! You lost the battle.
Russell wrote Spacewar on a PDP-1, an early Digital Equipment Corporation (DEC) interactive mini computer which used a cathode-ray tube display and keyboard. Significant improvements were made later in the spring of 1962 by Peter Samson, Dan Edwards and Martin Graetz.
Although the game was a big hit around the MIT campus, Russell and his team never profited from the game. They never copyrighted it. Besides, they were hackers who wanted to do it to show their friends. So they shared the code with anyone who asked for it.
5. The computer virus was initially designed without any harmful intentions
In 1983, Fred Cohen, best known as the inventor of computer virus defense techniques, designed a parasitic application that could ‘infect’ computers. He defined it as computer virus.

This virus could seize a computer, make copies of itself and spread from one machine to another via a floppy disk. The virus itself was benign and only created to prove that it was possible.
Later he created a positive virus called compression virus. This virus could be written to find uninfected executables, compress them upon the user’s permission and attach itself to them.
