CodeForFun

Many of the people who shaped our digital world started out by coding games for fun. For example, Steve Jobs and Steve Wozniak, the co-founders of multinational technology company Apple, began their coding careers as teenagers when they created the arcade game Breakout.

C-CODING

Computer code might look like a foreign language, but it is a language anybody can pick up quickly, with a little practice! Learn more about coding with DK’s Computer Coding, and on DKfindout!

GAMING WORLD

Computer games are so popular that the games industry is now worth more than the movie industry!

Space Shuttle

Spacecraft often run using old-fashioned computer systems because engineers are confident their programs do the job well, while making a new one is risky and expensive. NASA’s reusable spacecraft, the Space Shuttle, went into space using a computer designed in the 1970s. It had LESS CODE than most of today’s cell phones!

black-hat vs white-hat hackers

Coders who study and write malware are known as hackers. Those who write malware to commit crimes are known as “black-hat” hackers, and those who write programs to protect against malware are called “white-hat" hackers.

E-mail 😅

Most web pages are built using more than one programming language. An e-mail website, for example, is made with three programming languages: CSS, HTML, and JavaScript.

The domain name part of an email address has to conform to strict guidelines: it must match the requirements for a hostname, a list of dot-separated DNS labels, each label being limited to a length of 63 characters

FIRST COMPUTER VIRUS

Creeper system
The first computer virus, called “Creeper system”, was an experimental self-replicating virus released in 1971. It was filling up the hard drive until a computer could not operate any further. This virus was created by BBN technologies in the US.

Elk Cloner, written in 1982 by then-15-year-old Rich Skrenta of Pittsburgh, was a boot-sector virus designed to infect Apply II computers and was the first to be detected in the wild.

Brain, created in Pakistan in 1986, was the first PC virus to be found in the wild.

And the first antivirus program? Reaper, which was created to delete Creeper.

BBN Technologies, by the way, was the proud owner of the second domain name to be registered on the Internet, as we found out in last week’s question. Which was the first? 

The first domain name registered was Symbolics.com. It was registered March 15, 1985, to Symbolics Inc., a computer systems company in Cambridge, Mass.

It was not the first domain name created, however — that title goes to Nordu.net, a Scandinavian research collaboration, which created the domain Jan. 1, 1985. Nordu.net was used for the first root server (nic.nordu.net), according to DomainNameNews. However, once registration was permitted, Symbolics got in the door first.

The second domain name registered was Bbn.com, registered to BBN Technologies April 24, 1985.

The initial rounds of domain registration weren’t exactly a mad dash: By 1992, fewer than 15,000 .com domains had been registered. At the end of 2010, there were 205.3 million overall, according to VeriSign. And IPv6 is on deck.

FIRST PROGRAMMER-

The FIRST PROGRAMMER in the world was a WOMEN. Her name was Ada Lovelace and she worked on an analytical engine back in the 1,800’s.

At the age of 12, Lovelace conceptualized a flying machine.
After studying the anatomy of birds and the suitability of various materials, the young girl illustrated plans to construct a winged flying apparatus before moving on to think about powered flight. “I have got a scheme,” she wrote to her mother, “to make a thing in the form of a horse with a steamengine in the inside so contrived as to move an immense pair of wings, fixed on the outside of the horse, in such a manner as to carry it up into the air while a person sits on its back.”
