9 weird but true facts about technology
You can’t disagree with the steady walk of innovation however you can wonder about a portion of the absurdities from the previous couple of decades. Here are some facts about information technology and computers.
Printer ink can be save by changing the font
It is quite obvious that the fonts in computer are not of equal size. Some fonts are taller and some are thicker. You can save printer ink, if you are using a inkjet printer, by using a lighter font in your print work. The fonts with a lighter stroke use slightly less ink per page compared with a bolder font. It will likely to save about 10 per cent ink by changing to one of the lighter fonts. It can be seen when you have a lot to print.
WWW or world wide web was born after Email
There is a very interesting video on YouTube which tell that how emails were send when there was no world wide web. You can see the video by typing “How to send an Email – Database – 1984“. It is a clip taken from a TV show named “Database and the presenters demonstrated”.
The emails were sent using a revolving telephone and a computer to connect to Micronet. Think how tough it was as there were no URLs (Uniform Resource Locator) at that time and the Web Pages were just numbered. The webpage for emails was 7776.
QWERTY was designed to slow you down
The modern keyboard alphabet design forces the users to think why they are designed like that. The main purpose of QWERTY keyboards was to slow down the typewriters on the old manual typewriter machines. Those machines keys stuck and get into a tangle when someone tries to type fast. That’s why the designers designed QWERTY keyboards to place alphabets at a distance and it will slow down the typists.
Another assumption is that telegraph operators designed the QWERTY layout as it was easier to decipher Morse code.
If you want to use faster keyboard design use Dvorak layout in the language settings or purchase a Dvorak keyboard.
92 per cent of the world’s currency is digital
The currency used online is far more than the currency used in real life. There are many ways to earn and spend money online. The money we use physically is round about 8 percent of the whole currency.
This is fact that most transactions are done electronically worldwide to make it safer and easier. Banks give and get money electronically with credit/debit cards. Might be a good idea to revisit all those hacker movies where a computer hacker gets billions in just a few minutes.
Domain name registrations were free till 1995
Domain name registration is going harder as you have to pay and choose a good name. There is an annual fee that the domain owner has to pay. Till 1995 there were no fees of registering a domain name. It was in 1995 that a company called Network Solutions was granted the rights to charge people for domain names. When the fees were charged they were very high prices typically started at $100 per two years of registration.
National Science Foundation was charging 30 per cent of this was a fee to create an ‘Internet Intellectual Infrastructure Fund’. In 1997 it was reversed in bringing the charge down to $70 for two years.
In 1956, 5 megabytes (5MB) of data weighed a ton
In 1956 RAMAC (Random Access Method of Accounting & Control) was launched by IBM and it was the first computer with a hard drive similar to today’s PCs. It used magnetic disks and a moving head to read and write data.
The entire cabinet considered 1000kg and the 5MP data was put on 50 huge aluminum disks and it was coated with magnetic iron oxide. The speed was1200rpm at which the disks rotated and the machines were leased for $3,200 per month.
Russia built a computer that ran on water: in 1936
Vladimir Lukyanov a Russian scientist made a computer using water in 1936. It had gears, pivots, leaver and beads for power source to function. It was able to solve partial differential equations. The pictures of interconnected tubes full of water can be seen in Lukyanov computer.
Fine-tuning taps and plugs changed the flow of water whilst the end result was observed by measuring the level of water in certain tubes This was also known as Water Integrator and it was make for checking cracking in concrete. It can be seen now in Moscow’s Polytechnic Museum.
QWERTY vs ABC layouts in advanced graphing calculators
Graphic calculators with modern keyboards were introduced by Texas Instruments to solve the problem of solved the problem of digital diaries with QWERTY keyboard. They were not allowed in exams because they were fitting in the category of computers with their QWERTY keyboards.
Wikipedia needs an army of anti-vandal bots
Wikipedia is the largest freely available knowledge source on internet for a very long time. The data is added by people and a person can alter the data after registering. It can result in vandalism meaning that someone with hatred can edit the content as well.
Wikipedia has a very strong moderation system but there is not much that a person can do in terms of actively monitoring alterations and correcting those changes that thug have made.
There are around 1941 authorized bots are used on over 38,818,267 pages or Wikipedia. A bot named ClueBot-NG is used to track the changes a vandal has made and corrects them back.
