Since the early days of the internet, there has not ceased to be the use of search engines to locate the myriads of information available online. The use of search engines is indispensable to locate the information you need. If you have used the Internet for up to 10 years and over, you would remember search engines like Lycos, AskJeeves, Altavista and so on. Even though these ones have faded out and more prominent search engines like Yahoo and Bing, which is powered by software giant Microsoft, have come to stay, none of them stands out or is as popular as Google.

Today, Google as a search engine is undoubtedly the number one, such the word, “Google” has been recognized as a verb in the Oxford dictionary used as a synonym for “search.”

Now that dependence on Google for is that high, it only makes sense for one to know how to get Google to provide exactly the kind of information they want. How is this done?

What follows is a list of formats which you can use to get Google to give you just what you want. These few tricks from will help you become a Google power user.

Search exact: 

If you are looking for an exact phrase, use quotation marks like this: “the evening of December 25”

Exclude a word:

Add a hyphen “-“ before a word to exclude a search term. This is useful if you are searching for a word with several meanings. For example, you could type: Terminator –movie, to get results for the word terminator apart from the movie.

Search within a site:

This is used to search for items but restricting the results to within a particular site. The keyword is “site:” For example, ebola

Related websites:

Find websites similar to one you already know. Keyword is “related:” for example, related:

Find news related to a particular location:

Use this on Google news to find stories coming from a particular location. Keyword to use is “location:” For example, disease outbreak location:Lagos

Search for a particular file type:

If you are looking for files of a particular file format use the keyword, “filetype:” followed immediately by the file type such as doc, pdf, xls. An example is, “2014 curriculum filetype:pdf”

Using asterisk sign:

The asterisk * sign is used as a wildcard and helps you find a missing word in a phrase. For example, “the effects of * petrol”

Using OR

If you want to find pages with one of several words, use a capitalized OR. Without OR, results will show pages that include all the terms. An example is, “World Cup 2014 OR 2010”

More kkeywords that exist in Google search are: WEATHER, example, weather:Abuja; TIME, example, time:London; APPL for stock quotes; and DEFINE for definitions, for example, define jingoisms.

Aside from the examples above, Google does not usually recognize punctuation or grammar. However, punctuation and symbols that do work in Google search include: @, #,  $, +,  for searching social tags,  hash tags, prices and blood type respectively.

Google has other services to give you results tailored to your needs such as Google Images for searching for pictures related to a particular word or phrase you enter; you can also upload an image to find out more about it.

Google Goggles lets you search the web using your mobile phone’s camera instead of words. Simply take a picture of the item you want to search for and look at the results.

Google Trends lets you explore trending search topics on Google and see what other people are searching for.

Last year, Instagram introduced an enhanced comment filter that uses machine learning to spot offensive words and phrases in challenging contexts. Now, the company is expanding similar coverage to photos and captions. Today, it announced that it will use AI to “proactively detect bullying” before sending content to human moderators for review.

The new feature will roll out to users in the coming weeks, launching in time for October’s National Bullying Prevention Month in the US and just before Anti-Bullying Week in the UK. The same technology is also being added to live videos to filter comments there as well.

This is the first product announcement under new Instagram chief Adam Mosseri who took over following the hasty departure of co-founders Kevin Systrom and Mike Krieger last month. The split was reportedly due to simmering tensions between the pair and parent company Facebook, which has frequently meddled with Instagram’s product.

With public trust in Facebook continuing to fall, Instagram remains the bright spot in the company’s product lineup. It’s popular, profitable, and it has yet to be tainted by the scandals that have undermined Facebook. In this context, using AI to help weed out offensive content and keep Instagram a home for good vibes is extremely important.

A story published in Wired last year explained some of the details of Instagram’s machine learning comment filters, but it’s well-established that this sort of technology is no silver bulletfor content moderation. AI is cheap to deploy at scale, yes, but it still has trouble dealing with human context and nuance. That’s why it’s good that these new bullying filters also send content to human moderators to perform the final check. Automation without oversight is a recipe for disaster.

Interestingly, Instagram says it’s not just analyzing photos captions to identify bullying, but also the photo itself. Speaking to The Verge, a spokesperson gave the example of the AI looking for split-screen images as an example of potential bullying, as one person might be negatively compared to another. What other factors the AI will look for though isn’t clear. That might be a good idea considering that when Facebook announced it would scan memes using AI, people immediately started thinking of ways to get around such filters.

Along with the new filters, Instagram is also launching a “kindness camera effect,” which sounds like it’s a way to spread a positive message as a method to boost user engagement. While using the rear camera, the effects fill the screen with an overlay of “kind comments in many languages.” Switch to your front-facing camera, and you get a shimmer of hearts and a polite encouragement to “tag a friend you want to support.”

Yes, Facebook Dating is a real thing. And we may have just received a sneak peek.

Jane Manchun Wong — an app researcher who’s spotted Facebook features in the past, like Talent Show — posted photos from what she claims is an internal test of Facebook Dating.


The company wouldn’t say whether these pics are the real deal, although it did confirm it’s testing Facebook Dating internally.

Two months ago, at its F8 developer conference, Facebook shared that it was developing a dating app. Aspiring yenta Mark Zuckerberg explained it was “going to be for building real, long-term relationships, not hookups.”

Later, on its blog, Facebook dished out a few more details: “People will be able to create a dating profile that is separate from their Facebook profile — and potential matches will be recommended based on dating preferences, things in common, and mutual friends. They’ll have the option to discover others with similar interests through their Groups or Events.”

From Wong’s photos, it looks like the app will let you prevent your current Facebook friends from seeing your dating profile, thus avoiding potential embarrassment. It’ll also offer a variety of gender options, including trans man, trans woman, and non-binary.

No word on when, exactly, Facebook Dating will become available to the public. Guess you’ll just have to make do with Tinder, Bumble, OKCupid, Happn, Grindr, Hinge, and the thousands of other dating apps out there in the meantime.

Security researchers have discovered that it’s possible for hackers to change both the content and the sender of a WhatsApp message after you’ve received it …

This includes the ability to change quoted messages, to make it appear you said something you didn’t.

CNET reports that the possibility was discovered by Check Point Software Technologies.

The firm] found that hackers can create a hacked version of the app and alter a quoted message (a past one that someone is replying directly one) to change the content or sender.

The hacker would, however, need to be part of the chat, so the vulnerability mostly applies to group chats.

WhatsApp told the NYT that it was not aware of the technique being used in the wild, and a cure would be worse than the problem.

One solution would be to create transcripts of every message exchange to verify the accuracy of every quote. Creating such a transcript is a significant privacy risk because those accounts of what people wrote to each other must be stored somewhere, the company said.

All WhatsApp messages are protected by end-to-end encryption, which means that only those within a chat would be able to exploit the loophole. Storing a transcript would effectively mean removing that end-to-end encryption.
