People who love planes are celebrating an aviation landmark this year with the 50th anniversary of the maiden flight of the supersonic plane Concorde.
Back in March1969 Concorde took to the skies for the first time for a 29 minute flight at a speed not exceeding 480 km/h, it was able to break the sound barrier in October of the same year.
This achievement was the highlight of a long journey from the first flight recorded in 1903 by the Wright Brothers.
Since early Greek mythology and the story of Icarus humans have always been enchanted by the idea of flight. The modern age of aviation began with the first hot air balloon designed by the Montgolfier brothers in 1783. Experiments with gliders provided the groundwork for heavier-than-air craft, and by the early-20th century, advances in engine technology and aerodynamics made controlled, powered flight possible for the first time. The modern airplane with its characteristic tail was established by 1909 and from then on the history of aircraft became tied to the development of more and more powerful engines.

DuckDuckGo a search engine that puts privacy first
DuckDuckGo a search engine that puts privacy first is an Internet search engine that emphasizes protecting searchers’ privacy and avoiding the filter bubble of personalized search results.
Are you concerned about how much data is being tracked when you search on Internet?
Are you fed up with being bombarded by targeted adverts when you open a webpage?
Let’s have a look at these issues and what you can do to combat this.
You may not be surprised to learn that Google, and other search engines have all of your search history stored up.
You can delete it though – If you would prefer not have a huge list of search queries stored up, then connect to Google’s history page, click Menu (the three vertical dots) and then click on Advanced – All Time – Delete.
If you want to stop Google tracking your searches for ever, connect to the activity controls page and toggle tracking off.
That’s it, you are now free from tracking!
Not only do they record your searches, but Google also keeps an eye on your location.
Google’s location history, or timeline page, serves up a Google Map and allows you to select specific dates and times and see where you were.
The accuracy depends largely on whether you were signed into your Google account and if you had a phone or tablet with you.
How you can delete it : When you visit the timeline page you can hit the settings cog in the bottom right-hand corner of the screen and select delete all from there.
There’s also the option to pause your location history by clicking the button in the bottom left of the screen.
If you’ve ever wanted to remove your records, virtually [sic] from the internet, a Swedish website Deseat.me makes use of your Google account to do just that.
Deseat.me can show you all your online and social media accounts and lets you delete yourself from them.
How to delete it : Go to Deseat.me and enter your Gmail address.
It will bring up all the online accounts linked to that email address and allow you to delete them.
But for now, let’s look at a way that you can still search the Internet without your data being tracked or being bombarded by targeted advertising from Google or other search engines :
DuckDuckGo distinguishes itself from other search engines by not profiling its users and by deliberately showing all users the same search results for a given search term, and emphasizes returning the best results, rather than the most results, generating those results from over 400 individual sources, including crowdsourced sites such as Wikipedia, and other search engines like Bing, Yahoo!, and Yandex.
The company is based in Paoli, Pennsylvania, in Greater Philadelphia.
Some of DuckDuckGo’s source code is free software hosted at GitHub under the Apache 2.0 License, but the core is proprietary. The company registered a shortened URL redirect at ddg.co on 20 September 2013. On 21 May 2014, DuckDuckGo launched a redesigned version that focused on smarter answers and a more refined look. The new version added often requested features such as images, local search, auto-suggest and more.
On 18 September 2014, Apple included DuckDuckGo in its Safari browser as an optional search engine. On 10 November 2014, Mozilla added DuckDuckGo as a search option to Firefox 33.1. On 30 May 2016, The Tor Project, Inc made DuckDuckGo the default search engine for Tor Browser 6.0.
DuckDuckGo was founded in 2008 by Gabriel Weinberg, an entrepreneur who previously launched Names Database, a now-defunct social network. Initially self-funded by Weinberg, DuckDuckGo is now advertising-supported but the user has the option to disable ads.
The search engine is written in Perl and runs on nginx, FreeBSD and Linux. DuckDuckGo is built primarily upon search APIs from various vendors. Because of this, TechCrunch characterized the service as a “hybrid” search engine. At the same time, it produces its own content pages, and thus is similar to Mahalo, Kosmix and SearchMe.
We didn’t invest in it because we thought it would beat Google. We invested in it because there is a need for a private search engine. We did it for the Internet anarchists, people that hang out on Reddit and Hacker News.
Fred Wilson, 2012 TechCrunch Disrupt Conference in New York
In a lengthy profile in November 2012, the Washington Post indicated that searches on DuckDuckGo numbered up to 45,000,000 per month in October 2012. The article concluded “Weinberg’s non-ambitious goals make him a particularly odd and dangerous competitor online. He can do almost everything that Google or Bing can’t because it could damage their business models, and if users figure out that they like the DuckDuckGo way better, Weinberg could damage the big boys without even really trying. It’s asymmetrical digital warfare, and his backers at Union Square Ventures say Google is vulnerable.”
At its keynote speech at WWDC 2014, Apple announced that DuckDuckGo would be included as an option for search on both iOS 8 and OS X Yosemite.
On 21 May 2014, DuckDuckGo officially released the redesigned version that focused on smarter answers and a more refined look. The new version added many new features such as images, local search, auto-suggest, weather, recipes and more.
in July 2016, DuckDuckGo officially announced the extension of its partnership with Yahoo! that brought new features to all users of the search engine, including date filtering of results and additional site links. It also partners with Bing, Yandex and Wikipedia to produce results or make use of features offered. The company also confirmed that it does not share user information with partner companies, as has always been its policy.
DuckDuckGo’s results are a compilation of “over 400” sources, including Yahoo! Search BOSS; Wikipedia; Wolfram Alpha; Bing; its own Web crawler (the DuckDuckBot); and others. It also uses data from crowdsourcedsites, including Wikipedia, to populate “Zero-click Info” boxes – grey boxes above the results that display topic summaries and related topics.
Weinberg has refined the quality of his search engine results by deleting search results for companies he believes are content mills, like Demand Media’s eHow, which publishes 4000 articles per day produced by paid freelance writers, which Weinberg says is, “…low-quality content designed specifically to rank highly in Google’s search index.” DuckDuckGo also filters pages with substantial advertising.
In addition to the indexed search results, DuckDuckGo displays relevant results, called Instant Answers, on top of the search page. These Instant Answers are collected from either 3rd party APIs or static data sources like text files. The Instant Answers are called zeroclickinfo because the intention behind these is to provide what the user is searching for on the search result page itself so that the user does not have to click any results to find what they are looking for. As of August 20, 2016, there are 989 Instant Answers active.
The Instant Answers are open source. They are maintained on Github and anyone can build or work on them.
Tor hidden service
In August 2010, DuckDuckGo introduced anonymous searching, including an exit enclave, for its search engine traffic using Tor network and enabling access through a Tor hidden service. This allows anonymity by routing traffic through a series of encrypted relays.
In 2011, DuckDuckGo introduced voice search for users of the Google Chrome voice search extension.
DuckDuckGo includes “!Bang” keywords, which give users the ability to search on specific third-party websites – using the site’s own search engine if applicable. As of 2017, approx. 10,000 “bangs” for a diverse range of Internet sites are available.
DuckDuckGo has a mobile app available for iOS and Android which forces websites to use HTTPS, blocks web trackers, and rates sites based on their privacy practices.The service, released in January 2018, is also available as a browser extension for Google Chrome, Mozilla Firefox, and Apple Safari.
DuckDuckGo earns revenue by serving ads from the Yahoo–Bing search alliance network, and through affiliate relationships with Amazon and eBay.
In a June 2011 article, Harry McCracken of Time magazine commended DuckDuckGo, comparing it to his favorite hamburger restaurant, In-N-Out Burger:
It feels a lot like early Google, with a stripped-down home page. Just as In-N-Out doesn’t have lattes or Asian salads or sundaes or scrambled eggs, DDG doesn’t try to do news or blogs or books or images. There’s no auto-completion or instant results. It just offers core Web search—mostly the “ten blue links” approach that’s still really useful, no matter what its critics say…As for the quality, I’m not saying that Weinberg has figured out a way to return more relevant results than Google’s mighty search team. But DuckDuckGo…is really good at bringing back useful sites. It all feels meaty and straightforward and filler-free…
The barebones approach cited in his quote have since changed; DuckDuckGo now has auto-completion and instant results for example. McCracken included the site in Time’s list of “50 Best Websites of 2011”.
Thom Holwerda, who reviewed the search engine for OSNews, praised its privacy features and shortcuts to site-specific searches as well as criticizing Google for “tracking pretty much everything you do”, particularly because of the risk of such information being subject to a U.S. government subpoena.
In 2012, in response to accusations that it was a monopoly, Google identified DuckDuckGo as a competitor.
Weinberg was reportedly “pleased and entertained” by that acknowledgment.
How much do you know about social media – are you really savvy about the world of social media or just on the edges?
Social media are computer-mediated technologies that facilitate the creation and sharing of information, ideas, career interests and other forms of expression via virtual communities and networks. The variety of stand-alone and built-in social media services currently available introduces challenges of definition; however, there are some common features:
Social media are interactive Web 2.0 Internet-based applications.
User-generated content, such as text posts or comments, digital photos or videos, and data generated through all online interactions, is the lifeblood of social media.
Users create service-specific profiles for the website or app that are designed and maintained by the social media organization.
Social media facilitate the development of online social networks by connecting a user’s profile with those of other individuals or groups.
Users typically access social media services via web-based technologies on desktop, computers, and laptops, or download services that offer social media functionality to their mobile devices (e.g., smartphones and tablet computers). When engaging with these services, users can create highly interactive platforms through which individuals, communities, and organizations can share, co-create, discuss, and modify user-generated content or pre-made content posted online. They introduce substantial and pervasive changes to communication between businesses, organizations, communities, and individuals.
Social media changes the way individuals and large organizations communicate. These changes are the focus of the emerging fields of technoself studies. Social media differ from paper-based media (e.g., magazines and newspapers) or traditional electronic media such as TV broadcasting in many ways, including quality, reach, frequency, interactivity, usability, immediacy, and permanence. Social media outlets operate in a dialogic transmission system (many sources to many receivers).
This is in contrast to traditional media which operates under a monologic transmission model (one source to many receivers), such as a paper newspaper which is delivered to many subscribers, or a radio station which broadcasts the same programs to an entire city. Some of the most popular social media websites are Baidu Tieba, Facebook (and its associated Facebook Messenger), Gab, Google+, Myspace, Instagram, LinkedIn, Pinterest, Tumblr, Twitter, Viber, VK, WeChat, Weibo, WhatsApp, Wikia, Snapchat, . These social media websites have more than 100,000,000 registered users.
In America, a survey reported that 84 percent of adolescents in have a Facebook account. Over 60% of 13 to 17-year-olds have at least one profile on social media, with many spending more than two hours a day on social networking sites.
According to Nielsen, Internet users continue to spend more time on social media sites than on any other type of site. At the same time, the total time spent on social media sites in the U.S. across PCs as well as on mobile devices increased by 99 percent to 121 billion minutes in July 2012 compared to 66 billion minutes in July 2011.
For content contributors, the benefits of participating in social media have gone beyond simply social sharing to building a reputation and bringing in career opportunities and monetary income.
Observers have noted a range of positive and negative impacts of social media use. Social media can help to improve individuals’ sense of connectedness with real or online communities, and social media can be an effective communication (or marketing) tool for corporations, entrepreneurs, nonprofit organizations, including advocacy groups and political parties and governments. At the same time, concerns have been raised about possible links between heavy social media use and depression, and even the issues of cyberbullying, online harassment and “trolling”. Currently, about half of young adults have been cyberbullied and of those, 20 percent said that they have been cyberbullied regularly.
Another survey was carried out among 7th grade students in America, which is known as the Precaution Process Adoption Model. According to this study, 69 percent of 7th grade students claim to have experienced cyberbullying and they also said that it is worse than face to face bullying.
However both the bully and the victim are negatively affected, the intensity, duration, and frequency are the three aspects that increase the negative effects on both of them.
On average, people pick up their smartphone 221 times a day to do things with it. It’s no secret that we are getting more and more addicted to these handsets, but have you wondered what effect that is having on your mind and your body?
What happens to your body when you are always on the phone?
Scientists are definitely curious and have a few ideas about the ramifications of smartphone usage. You can measure your own smartphone usage to gather data about how often you check it, and then compare it with the smartphone addiction checklist to know if you have a problem.
An incredible 81% of us have our smartphones within arm’s reach nearly all the time, and one in five young people admit to checking their screens every five minutes.
Are our devices completely safe? We haven’t been using cell phones long enough to fully study long-term impacts and say using them definitively causes specific diseases. But then again, it took decades to prove a surefire link between smoking cigarettes and lung cancer, too.
Now, I’m not suggesting we all ditch our phones … I rely on mine for so many things.
But the following findings may give you reason to take some commonsense cell phone safety precautions to minimize your risk.
It’s curious that so many people obsessively read their horoscopes.
According to a studies, many Americans believe astrology is scientific.
The study also revealed that skepticism of astrology is decreasing, and indeed you don’t have to look far online to find the strong community of young, cool, perfectly normal people who obsess over their zodiac signs.
Some of the most popular websites, newspapers and magazines regularly post articles about star signs.
Today Susan shares some of her surprising skills – that being her almost amazing accuracy in reading the stars.
