  Roy Allela’s six-year-old niece was born deaf. She found it difficult to communicate with her family, none of whom knew sign language. So Allela – a young Kenyan technology evangelist who works for Intel and tutors data science at Oxford University – invented smart gloves that convert sign language movements into audio speech. The gloves – named Sign-IO – have flex sensors stitched onto each finger. The sensors quantify the bend of the fingers and process the letter being signed. The gloves are paired via Bluetooth to a mobile phone application that Allela also developed, which then vocalizes the letters. “My niece wears the gloves, pairs them to her phone or mine, then starts signing and I’m able to understand what she’s saying,” says Allela. “Like all sign language users, she’s very good at lip reading, so she doesn’t need me to sign back.” Allela piloted the gloves at a special needs school in rural Migori county, south-west Kenya, where feedback helped inform one of the most ...

 Before Explorer was introduced in Windows 95, the Windows desktop was a very different place. The icons on your desktop did not represent files; rather, when you minimized a program, it turned into an icon on the desktop. To open a minimized program, you had to hunt for its icon, possibly minimizing other programs to get them out of the way, and then double-click it. (You could also Alt+Tab to the program.) Explorer changed the desktop model so that icons on your desktop represent objects (files, folders) rather than programs. The job of managing programs fell to the new taskbar. But where did the windows go when you minimized them? Under the old model, when a window was minimized, it displayed as an icon, the icon had a particular position on the screen, and the program drew the icon in response to paint messages. (Of course, most programs deferred to DefWindowProc which just drew the icon.) In other words, the window never went away; it just changed its appearance. But with the...

Bluetooth is a wireless technology standard used for exchanging data between fixed and mobile devices over short distances using UHF radio waves in the industrial, scientific and medical radio bands, from 2.402 GHz to 2.480 GHz , and building personal area networks. It was originally conceived as a wireless alternative to RS-232 data cables. The name “Bluetooth” was proposed in 1997 by Jim Kardach of Intel, who developed a system that would allow mobile phones to communicate with computers. At the time of this proposal, he was reading Frans G. Bengtsson's historical novel The Long Ships about Vikings and the 10th-century Danish King Harald Bluetooth. Bluetooth is the Anglicised version of the Scandinavian Blatand/Blatann . It was the epithet of King Harald Bluetooth who united dissonant Danish tribes into a single kingdom. The implication being that Bluetooth unites communication protocols. The Bluetooth logo is a bind rune merging the Younger Futhark runes Runic letters, Harald...

  Google is the legit owner of blogger, and it is a publishing website hosted by Google itself. Pyra Labs developed this website in their time and Google finally purchased the blog publishing service in the year 2003. This free blog is generally accessed from its subdomain as in ( Blogspot.com ) Blog – Publishing is literally an entire free blogging service. Which includes blogger themes and its gadgets and entirely any other supporting plugin. Except only if you have a budget for a premium blog, which you would want to buy third party themes and also and it’s highly recommended to use a custom domain only if you have a budget ready to pay for. To upgrade your domain to a custom domain as in e.g. moving from example.blogspot.com to example.com , you will need a domain registration company and the good news is that most of them have amazing discount to match your budget annually. Which I recommend domain.com , Hostinger.com and I am not an affiliate worker for them, their names a...

 The oldest, continuously used national flag is that of Denmark. The current design of a white Scandinavian cross on a red background was adopted in 1625 and its square shape in 1748. In Denmark, it is known as the 'Dannebrog' or 'Danish cloth'. Although Denmark was never part of the Roman Empire, similar designs were used by the Empire to represent provinces, as the white cross is symbolic of Christianity. The Scandinavian cross has its horizontal stripe slightly to the left hand side of the square as you face it. Although there is no prescribed definition of what constitutes “continuous" use, the Danish flag was certainly in use in the 1370s, as the Gelre Armorial by Claes Heinenzoon (or Heynen 1345-1414) shows. It was also certainly used in the naval battles during the war against Sweden in the 1560s, as shown in watercolour in Rudolf Dewenter’s Bericht von Pulver und Feuerwerken from 1585. In his War Articles, promulgated on 8 May 1625, King Christian IV issued...
