Tech talk

      Jump to latest update        

Technology is growing by leaps and bounds, day by day. But many of us are so engrossed in our daily routine that we fail to notice most of what is happening around us. Its impossible to keep track of everything that is happening. Yet when we come across certain things, we wish that we could have known about this earlier. Tech Talk serves the purpose. No talk about gadgets here.

Originally the idea was to  post elaborate details on operating social media like whatsapp, as I came  across quite a few people, who did not understand it and were at the mercy of the kids at home. Thats reserved for future posts if I have any takers 🙂 .

For now I am concentrating on the useful websites that I came across, which I felt I could have known earlier. You too never knew them, did you?

Lets get started!!!

1) Search Engines

Immediately Google comes to mind for most of us, as it is the most widely used search engine, followed by Yahoo and Microsoft’s Bing . Then there is Russia’s  Yandex, China’s Baidu & Newyork based AOL. 

In  you can ask questions and possible answers are provided, with a large list of other related queries. It is popular for accomodating colloquial language.

Dogpile is a metasearch engine which fetches results from other search engines and presents them in a combined form to the user. Apart from these there are numerous other search engines operating all around the world, though some are country or region specific like the japanese goo .

The purpose of touching upon search engines is to introduce these 3 search engines which caught my attention

Know more

1) Wolfram alpha

This is an online search that provides direct answers to queries rather than putting forth a list of webpages that may possibly have the solution. It is the most informative sites online. It can provide comprehensive results based on computational facts, but cannot answer queries requiring a narrative response.

What Wolfram Alpha says

With deep knowledge about pop culture, personal finance, nutrition, health and countless other topics, Wolfram|Alpha can answer complex factual questions at home, at school or in the office. Look up Oscar winners, compute nutritional values for meals, keep tabs on your stock portfolio, check the weather or convert recipe measurements—Wolfram|Alpha’s powerful algorithms and massive knowledgebase can help with everyday tasks from cooking to homework to changing a tire. When work is over, turn to Wolfram|Alpha to answer questions about books, movies and television shows; analyze personal health and exercise; or just tell a joke.”


Wolfram alpha is much more than a search engine. There are so many  cool things you can do with it and listing everyone of them here is absolutely impossible. Just get down to the list of  options provided below the search bar, and start exploring. You can get info on practically anything under the sun.

 Try it out here. A few of them are listed below.

a) Nutrition

Enter any  name of food and it provides nutritional information. You can create nutrition labels as well as compare two foods by adding  vs in between.


b) Find out where you are

If you type ‘Where am I’ in the search box, it will track you down using your IP address. It will give you  your location as well the map. It can also provide you information on any IP number that you may enter.

c ) Solving Maths

It can solve elementary maths as well as find factors, plot a function, solve differential equation  and much more.


d) Geographical facts

You can find out a location using longitude and latitude, generate world map for a particular statistic, like population. Get researching on historical monuments or specific locations.


e) Finances

You can get details on stock markets like analysing and comparing stocks, convert currencies and find out tax deductions. You can also compute interest on loans and mortgages, calculate the necessary income for an equivalent standard of living when relocating to a new place. For instance if you enter ‘moving from Chennai to Doha at a salary of QR 10,000’, you get info on cost of living comparisons, population, climate comparison etc.

6) Generates password

Upon entering Alphanumeric password in the search bar, it generates a strong 8 character password and also gives a list of alternate passwords.

2) Duckduckgo

This is the search engine that does not track you. It does not store IP numbers and does not collect or share personal information. It offers users genuine privacy and options for customisations, though it does use cookies where deemed necessary.

But if you are used to getting  all your information from google, then you may not be convinced. Still if you value your privacy, this one may be for you. Get it here.

It is also available as an app in both android play store  and apple store.

3) Qwant

This is a French search engine, which also values your privacy. It does not use cookies, or collect browsing data. Within 4 years, it has grown to be used by 21 million people across 31 countries. It has 31 different search category like music, health, cars etc apart from the standard ones.

The company believes that Artificial intelligence can be up and working even without collecting user details. It has also gone a step further, by making its source code available to third party data protection agencies, for them to continually verify if there is data breach. It has been integrated with mozilla firefox.

What Qwant  says

Designed and developed in France, Qwant is the first European search engine with its own indexing technology, which protects the privacy of its users by refusing all tracking devices, including for advertising. Contrary to the main search engines on the market, Qwant does not install cookies on the user browser, does not want to know who the user is or what he/she does, and does not keep individual logs of user queries. Qwant’s friendly interface allows users to find answers efficiently from the Web and social networks. It respects neutrality. Qwant considers all indexed websites and services with no discrimination, without altering the ranking of results according to its own interests.”

That is a powerful statement, considering the present status on privacy being handled by search engines and social media. Europe takes its privacy very seriously! Qwant becomes the only Western search engine to be available in China from Jan 2018. Try it here.

It is  also available as Qwant mobile on google play as well as iOS, providing a secure browser. They also have a dedicated search engine, Qwant Junior for kids which filter out any inappropriate content.

Qwant has created a dedicated search engine for music with 20 to 30 million songs indexed so far. uses artificial intelligence and machine language to automate the discovery, filtering, and display on one single page of all the data related to a musician (discography, news, events, videos, photos…) as well as links to stream their music from Deezer, YouTube or Spotify.

Qwant Music also lets an artist customize their profile page, have access to their site analytics, add their own content and even directly sell their songs and tickets to events. (

Qwant also has a dedicated map search, Qwant maps which is in the beta stage. Qwant maps give details of restaurants, supermarkets, pharmacy, banks etc. available  at places selected on the map.


2) Manualslib

You can also share the documents on social networks, compare specifications of two different products as well as look up troubleshooting.

3)Wayback machine

I came across this some time back and was pleasantly surprised. Two of the websites which I had been closely following are no longer hosted, and I was pretty upset that I lost track of so much valuable content. Come, Wayback machine!

It is a digital archive of the world wide web created by a non profit organisation called the Internet Archive. It is a huge digital library offering free universal access to books, movies, music  and billions of archived web pages.

Its software crawls the web and downloads all publicly accessible  webpages, creating archives. Data restricted by the publisher or stored in inaccessible databases are not available, but you can find pretty much everything else. 

You can use it to view dead websites or dated news reports. You can also  use it to view how a particular website looked few years back.

Go to the internet archive’s website,

In the search bar, type the keywords or the website URL. You can select the name of the site from the search results that appear. When you click on the website, a page appears with black bar graphs showing the years and below that a calender for 12 months.

Wayback machine screen shot

The black bars show the number of times the page was archived by the wayback machine. When you click on a particular year, the 12 month calender for that year appears.

Click on the colored date to access the website on that particular date. White dates cannot be accessed as it has not been archived on that day. Clicking on a date in August 2000, took me to the website.

So using the wayback machine you can access long lost websites.
