12 Weired But True facts about technology

You can’t argue with the relentless march of technology but you can marvel at some of the absurdities from the past few decades. Hitesh Raj Bhagat rounds up a bunch of facts and anecdotes that sound so ridiculous, you will question their authenticity.

1.    Changing Fonts Can Save printer Ink

That’s right, fonts are not created equal. People create different kinds of fonts for all kinds of reasons: to convey a message,  for decoration, embellishment or as iconography. The theory is, if you use a ‘lighter’ font (with a lighter stroke), you will use slightly less ink per page. Based on the assumption that you are only printing with inkjet printers that use the old style cartilages (not ink tanks, and not toner based laser printers), you will likely save about 10% ink by switching one of the lighter fonts. Of course, the flipside to this argument is that as a home consumer, you will never print enough volumes to actually see a benefits.

2.    Email Existed Before The World Wide Web

You probably don’t even think before composing a one line email message and sending it. But it wasn’t always so easy. There is an interesting clip on YouTube: “How to send an Email –Database-1984”. This was from a Tech TV show called database and the presenters demonstrated what it took to actually send an email back in those days. You had to use a computer and a rotary telephone to connect to a service called Micronet. This was pre-WWW, there were no URLs, just numbered WebPages. For emails, the webpage number was 7776.

3.    The QWERTY Layout Keyboard was Designed To Slow You Down

There are actually two theories to this. The first one starts to make sense when you look at manual typewriters. If someone type too fast, the keys would jam. QWERTY laced common alphabets at a distance from each other and slow typists down. Another theories is that telegraph operators designed the QWERTY layout because it was easier (and faster) to Decipher Morse code. Either way, there was no reason to keep using the layout, but it stuck and there was resistance to change. You can actually change your keyword layout to the faster Dvorak layout in the language settings (or just buy a new Dvorak keyboard).

4.    92% Of The World’s Currency is Digital

This means that most of money you earn, transect with, used to buy goods/services and so on exists. Only on computers and hard drives. Only an estimated 8% of currency globally is physical money. All the black money piles come from within this 8%. This is the fair estimate that economists seem to agree on through, not an exact figure. This is low percentage seems absurd but when you stop to think, it makes sense considering that most large transactions are done electronically anyway. Banks store electronically too and the 92% includes all kinds of transaction done using credit/debit cards and wire transfers. Might be a good idea to revisit all those hacker movies where a nerdy computer hacker manages to siphon billions off in just a few minutes.

5.    Domain Name Registrations Were Free Till 1995

Nobody really knew what the internet was capable of back then and this was a huge opportunity for people to own all kinds of domain names. It was in 1995 that a company called Network Solutions was granted the right to charge people for domain names. And it was expensive too: prices typically started at $100 per two years of registration. As much as 30% of this was a fee that went to the National Science Foundation to create an “Internet Intellectual Infrastructure Fund”. This fee was later reversed in 1997, bringing the charge down to $70 for two years.

6.    The Original Tron Was Snubbed for  ‘Cheating’

Greeks will know the Movie Tron (1982) starring Jeff Bridges. Bridges plays Kevin Flynn, a software engineer who gets digitized and downloaded into cyberspace where he interacts with other computer programs. There was a recent remake of his sci-fi classic that was very well received, again starring Jeff Bridges and a digitally altered, much younger version of him. However, the original movie was snubbed by the Oscar in 1982 (for a special effects award) because the academy thought they ‘cheated’ by using digital effects.

7.    In 1956, 5MegBytes (5MB) of Data Weighed a Ton

It was 1956 when IBM launched RAMAC, the first computer with something like a hard drive that we use today. By hard drive, we mean something that we used magnetic disks – a moving head was used to access and write that data. At the time, it was considered a massive leap in mass storage technology because it signified a shift: from punch cards and magnetic tap (which stored data sequentially) to randomly accessible hard drives, RAMAC itself stood for Random Access Method of Accounting and Control. The hole cabinet weighed over 100Kg and the 5MP data was spread over 50 huge aluminum disks, coated with magnetic iron oxide. The disk rotated at a speed of 1200rpm and the machines were leased for $3,200 per month back in the day.

8.    The X-Y Position Indicator for Displays – a.k.a The Mouse

When the first pointing device was invented in the early 60’s by Douglas Engelbart  and Bill English (they were part of the Stanford Research Institute), it was called the X- Y Position Indicator for Display Systems (referring  of course, to the X-Y axis). It was first used with the Xerox Alto computer and demonstrated in 1968, Engelbart in what is called the ‘Mother of all demos’ (check it out on YouTube). In 1968, Engelbart showed off word processing , graphics, windows, the linking and control using a ‘mouse’ – all these things made their way into modern computers. Engelbart was also responsible for the name mouse, coined simply because the cable sticking out the end of the device reminded him of a rodent’s tail.

9.    Russia Built A Computer That Ran on Water: In 1936

Before the miniaturization of transistors, computer had a much visible system of counting things like gears, pivots, beads and levers were often used and they needed some sort of power source to function. Vladimir Luckyanov built something like this in 1936but he used water to create a computer that solved partial differentiation equation. In images of the Luckyanov computer, you’ll see a complex system of interconnected tubes filled with water. Adjusting taps and plugs altered the flow of water (and changed the variables) while the end result seen by measuring the level of water in certain tubes. It was also called a water integrator and was originally design to solve the problem of cracking in concrete. It’s now found in Moscow’s Polytechnic Museum.

10.    QWERTY vs ABC Layouts in Advanced Graphing Calculators

Before smartphones, there was a time when digital diaries and advanced calculators were popular. They could be used to store simple forms of data and to perform calculation that student could use while solving differential equations apart from algebra and calculus capabilities, while advance calculators were ‘allowed’ to be taken into exam halls, many tested banned devices if they had QWERTY keyboards, simply because they fitted into the traditional definition of computer . Texas instruments solved the problem by introducing graphing calculators with keyboards that had an alphabetical layout.

11.    Wikipedia Needs an Army of Anti-Vandal Bots

Wikipedia’s mission is to make knowledge freely available to anyone with access to the internet. However, anyone with internet can also sign up and edit pages – which result in what they call vandalism (someone purposefully altering facts with malice). There is very robust moderation system but there’s only so much that a person can do, in terms of actively monitoring changes and correcting changes that vandals make. That’s where the bots – essentially computer programs –come in. the bots (like ClueBot –NG) Keep a track of all changes made to any page and instantly revert back to the ‘correct’ version if a vandal decides to change things. About 1941, bots are authorized for use on the 38,818,162 Wikipedia pages at last count.

12.    A 15–Year Old With a PC Hacked NASA in 1999

Between August and October of 1999, Jonathan James used his skills as a hacker to intercept data from the Defense Threat Reduction Agency or DTRA (a division of the US Dept. of Defense). He had access to over 3,000 messages, usernames and passwords of DTRA employees. He also obtained source code for the International Space Station (to control temperature and humidity), NASA was forced to shut down, for three weeks to fix the problem at an estimated cost of $41,000. He was ultimately sentenced when he was 16 –but it just goes to show what a 15-year old in South Florida, sitting with a computer and the right set of skills can do.
