Google drive to delete trashed files after 30 days,effective from October 13th,2020.

Google is changing how Google Drive handles trashed files and documents. Starting on October 13th, files in the trash will automatically delete after 30 days. The change means that Drive’s trash will work the same way as other Google products, like Gmail, for more consistent behavior across all of Google’s products.

Previously, Google Drive would keep files in the trash indefinitely unless you went in and emptied the trash to actually delete them for real, making it less of a “trash” and more of a way to just hide files you didn’t want to see. Administrators for G Suite will also still have the power to restore items that are deleted from the trash for up to 25 days for active users, so if you accidentally lost a critical work document, there’s still a chance to save it.

While the automatic trashing feature might be frustrating to some users, there may be actual benefits, too, since Google counts trashed files that aren’t deleted toward your Drive storage quota.

To make sure everyone is aware of the feature, Google will also add a banner notification to Google Drive as well as the specific Google Docs and Google Forms apps.

Do You Know Your Post Code?

What is a Postal Code?

We all know what postal code is, but not many of us know the technical (or historical) details behind it. For starters, ZIP is the abbreviation for Zone Improvement Plan. This was a system initiated in by the Post Office Department to handle increasing mail volumes by categorizing the U.S. into well-defined areas – making it one of the most organized and mature addressing systems in the world. The code became a tool for organizing and displaying demographic information while also allowing for the efficient sorting and dispatching of mail.

Over the span of 50 years, the ZIP Code was expanded from 5 digits to 9 and then to 11, with each digit indicative of the address location. With just the ZIP Code, it was easy to sort mails right down to the postal zone of a specific area or locality.

A Quick Lesson in History

Back in the 1940s, mail sorting was done manually. The Post Office Department’s mail staff depended entirely on local addresses and hand sorting addresses with postal offices. Post-war, the economic boom created an increase in mail volumes by 160%. Banks and companies began sending advertising mail to customers across the country. It became overwhelming for mail staff to manually sort through mails, while also ensuring they were delivered to the right addresses. During all this time, mail sorting was a laborious work which caused extended delays and erroneous deliveries. It took 8 to 10 employees to handle one mailed letter!

With the industrial boom, forward-thinking Postmasters attempted to create a system that would increase efficiency and reduce the manual sorting effort. In 1943, The program started the creation of a standardized coding system that would allow for easy mail grouping for distribution, logistics and transportation routing.

The system divided large cities into multiple 2-digit figures which would later be called local zone numbers. This 2-digit code helped the mail system with easy distribution, but it was limited to just the big cities, making it difficult to handle mails from other regions.

In 1944, Postal Inspector Robert Moon proposed the use of a 3-digit code system to categorize areas of the country by sectional center codes – which are central post offices of that region.

In 1983, the Postal Service expanded on the ZIP Code again, adding an additional +4 digits to the code. This 4-digit expansion would identify city blocks, streets or an office building. Today, the ZIP Code has been expanded to 11 digits, with each expansion adding a newer layer of information and adding to the accuracy of the address. As machines become more sophisticated with location precision, the ZIP Code plays an even more important role in ensuring the delivery of mail without the need of any additional written information.

Nigeria Postal Codes

Nigeria Postal Codes are numerics that consist of six digits numbers. According to NIPOST, the Nigerian nation is divided into nine regions which makes up the first digit of the code.
Nigeria Postal Code

The code of each region represents the first number, while the second and third digits when combined with the first, make up the dispatch district for out sorting. The last three digit stands for the delivery location which can be a rural area, an urban area or a post office facility.
The principal post head office in every region has a postal code that ends with 0001. For Instance, Ikeja HQ in Lagos is 100001; the lowest postcode is 100001 while the highest postcode is 982002.

The 3-digit code introduced by Moon was incorporated with the earlier 2-digit code to make a 5-digit code that provided information on the area, the code of the central office and the small post offices or postal zones that followed it. The use of ZIP Codes significantly reduced wrong deliveries and improved mail delivery services.

How are ZIP Codes Important for Businesses?

ZIP Codes are not just numbers that identify a location. They have become social identifiers – giving information on the demographics of the people of a certain region. Companies use Zip Codes as important data structures that give them a visual representation of their audience. With this information, companies are making major marketing decisions including the closing or opening of stores, launching new products or services and pivoting sales data into regions. ZIP Codes are POWERFUL and as such, it is necessary for any business to have VALID and ACCURATE ZIP codes.

Incomplete, Invalid ZIP Codes as the Biggest Challenge to Address Data Quality

In an age when businesses get data from multiple sources, the address data is usually flawed, incomplete or invalid. Human entry of data is often the cause of errors, typos, punctuation marks, wrong or mistyped ZIP Codes etc. Not to mention some people may also enter fake addresses making your data inaccurate and invalid. It is therefore important for organizations to verify their address data source to ensure that they have complete information for statistical analysis.

Other than fake or incomplete data, most address codes are also plagued with letters or punctuation marks that have no use in the code. These issues, though seemingly minor become major bottlenecks for businesses when they attempt to use their data for analysis. Flawed data also leads to flawed analysis – imagine the consequences of making a business decision based on flawed data!

While flawed data is one critical challenge, another major problem is that of addresses that do not comply with the address code. This means that businesses are storing and making use of address data that may not even be valid and neither is it verified for authenticity, leaving the business at legal, financial and operational risks.

Zoom, Microsoft and Apple take on remote learning challenges as kids head back to school

As school districts nationwide welcome students in August and September, teachers are facing an unprecedented number of hurdles. How do you keep students engaged when hands-on activities are limited? How do you take control of a classroom when discipline options are few and far between?

Many instructors got a trial run in March when classes were forced to go remote as the coronavirus spread throughout the globe. Tech helped buoy the transition and is playing a more central role as schools figure out what to do next.

Still, parents are facing what could be months of tech-related hurdles to overcome as they help keep kids focused on education from their homes.

Big tech companies like Microsoft, Apple and Google have responded to remote learning by bolstering their education offerings, which teachers say has been a lifeline in a sea of uncertainty. Zoom has also made some online learning updates, such as removing the 40-minute time limit for schools.

On Thursday, Zoom announced the ways it claims its video conferencing service will better facilitate remote school in the months ahead.

In a blogpost addressed to teachers, the video software company said it’s adding new controls to minimize disruptions and its enhancing tools related to focus groups.

To prevent Zoom bombings, teachers have an option that only allows authenticated users to join. That means participants would have to be signed into Zoom accounts using their school’s domain. Instructors can also require a meeting passcode to join.

Teachers will be able to disable video for individual students and create a virtual classroom seating arrangement, according to Zoom. And students will be able to hop from one focus group to another with ease.


Microsoft enhanced its Teams for Education platform to add tools specifically geared toward remote and hybrid learning situations.

It added a Together Mode to video calls, which brings all students into the same view to mimic what a teacher sees in a traditional classroom. It also added Live Reactions, live captions and transcripts for video meetings to enhance accessibility.

Leveling-up the features on Teams was meant to “extend the boundaries and borders of the classroom,” according to Anthony Salcito, vice president of worldwide education, at Microsoft.

Over 180,000 learning institutions currently use Microsoft Teams.


Apple has taken a varied approach to support educators and students in today’s distance learning environment.

Apple also launched a new Learning from Home website that offers tools and resources like instructional videos and webinars for teachers.


Google recently announced a number of upcoming tools meant to make virtual education easier.

The company is adding updates to its Google Meet conferencing platform, including a larger tiled view that can show up to 49 meeting participants at time. Google first launched its tile view, which allows instructors to see what more students are doing, in April.

But users could only view 16 participants in one glance. That wouldn’t work for classes with upwards of 30 students and more.

Since then, the company’s education arm has “seen all the ways that we need to adapt our tools to meet the challenges of a world relying on distance learning,” said Zach Yeskel, group product manager for Google for Education.

“Teachers have told us that it’s especially challenging to keep students engaged virtually, so we’re introducing a whole set of features that brings the best practices from an in-person classroom into the digital class.”

The tech giant also adding more moderation tools, so teachers can prevent disruptive students from joining meetings after they’ve been digitally kicked out or denied from entering twice.

Google is also flipping the switch on a setting that won’t start a meeting until the teacher has joined.

1. DNA

Scientists can now use deoxyribonucleic acid (DNA) to store and retrieve images. Videos, images, emails and other digital data up to 10,000 gigabytes in size can be stored in a smear of DNA.



Drones can now build a bridge by themselves. Oh, yes! With amazing ease, two quadrocopters have autonomously assembled rope bridge. This was done in Switzerland by deploying two drones connected with an anchor at two ends, creating a 120 m long bridge with 9 rope segments.

3.NOKIA 1100

The best selling mobile phone of all time was the Nokia 1100, made in Finland. A whooping 250 million units were sold. With this record, it is the most-sold electrical gadget in history, slightly ahead of the PlayStation 2.


The most dangerous virus ever created in the form of a worm is called ILOVEYOU. It attacked by replicating itself and crashing systems. It first arrived through e-mail messages as a love letter from a secret admirer. Once the email was opened and the attachment is clicked on, the virus spread fast.


It is predicted that by the year 2033, there would be anonymous robots that are designed to kill. It is understood that these robots can certainly spare a lot of human life, but they are also capable of identifying targets and killing them without any human input.


There are now smart water bottles that track a user’s water consumption, smart medical pill bottles that remind patients to take their pills, and innovative alcohol bottles that help consumers ensure authenticity of the product.


While it took the iPod just 3 years to reach a market audience of 50 million, it took radio 38 years and television, 13 years to reach the same market audience.


To combat global warming, scientists are proposing creative ways to artificially cool the atmosphere by either blocking the sun’s rays or sucking up excess CO2. The plan is to “hack” the planet back into shape.


In February 2009, Google tweeted for the first time ever on Twitter. The tweet was “I’m 01100110 01100101 01100101 01101100 01101001 01101110 01100111 00100000 01101100 01110101 01100011 01101011 01111001 00001010.” When translated from binary into English, the tweet says “I’m feeling lucky.”


LinkedIn, Youtube, Yelp, and SpaceX were all founded by former employees of PayPal. They are collectively known as PayPal Mafia. , Elon Musk, Peter Thiel and Reid Hoffman are members of this mafia.

Facebook to limit political ads ahead of November election

Facebook CEO Mark Zuckerbergon Thursday outlined several steps the social media site is taking to encourage voting and fight misinformation ahead of the US elections in November. In addition to efforts already in place, Zuckerberg said Facebook will expand its voter suppression policies and block new political and issue ads during the final week of the campaign.

In an interview with CBS This Morning about its election policies, Zuckerberg said Facebook will also add context to posts — including from President Donald Trump –that seek to broadly delegitimize mail-in voting or the outcome of the election.


“Anyone who is saying that the election is going to be fraudulent, I think that’s problematic and I think additional context needs to be added to that,” Zuckerberg told CBS This Morning co-anchor Gayle King. “This will definitely apply to the president. Once this policy goes into place, it will apply to everyone equally.”

Facebook will also remove posts with “implicit misrepresentations” about how or when to vote, Zuckerberg said in a post on the social network, as well as posts that claim people will get COVID-19 if they take part in voting.

Misinformation on social networks has been a top concern since Russian trolls used Facebook and other sites to post content aimed at sowing discord among Americans during the 2016 US presidential election. Facebook has also been under fire for not sending posts from politicians to fact-checkers, while also fending off allegations that it censors speech from conservatives.

Facebook will block new political and issue ads in the week before the Nov. 3 election since there may not be enough time to contest claims made in them, Zuckerberg said. Ads related to get-out-the-vote campaigns, and political ads purchased before the final week will continue to run. Facebook earlier this year rolled out a feature to let people turn off all political ads.

The company is also limiting forwarding on Messenger to help prevent misinformation from going viral, a method Zuckerberg said has already been effective on WhatsApp.

Given that many people are expected to vote by mail due to the coronavirus pandemic, Facebook is also preparing deal with “intense claims and counter-claims as the final results are counted,” Zuckerberg said. Among the polices the social media site is putting in place to deal with this: using its Voting Information Center to prepare people for not getting a result on election night; labeling posts politicians that declare victory before results are in; expanding its definition of high-risk people to include election officials to prevent attempts to pressure or harm them; ramping up enforcement against militias and conspiracy networks like QAnon.

On Tuesday,  Zuckerberg and Priscilla Chan announced they were are committing $300 million to support voting and election infrastructure in the US ahead of the November election.

“I believe our democracy is strong enough to withstand this challenge and deliver a free and fair election — even if it takes time for every vote to be counted,” Zuckerberg wrote in his post on Thursday. “But it’s going to take a concerted effort by all of us — political parties and candidates, election authorities, the media and social networks, and ultimately voters as well — to live up to our responsibilities.”

All you need to know about Domain name.

What is a Domain Name?

Domain name is the address of your website that people type in the browser to visit your website. For example,

In simple term, if your website was a house, then your domain name will be its address.

The whole internet is a giant network of computers. Each computer is assigned a number which is called an IP address, and it looks like this:

Now, this is not an easy to remember address. Imagine if you had to use this kind of addresses to visit your favorite websites.

To fix this problem, domain names were invented.

Domain names can have alphabets and numbers, which helps business owners create brandable names for their website’s address.

When Do You Need to Register a Domain Name?

Each day, over 46,000+ new .com domain names were registered during the third quarter of 2018.

Currently, there are over 140 million .com domain names already registered.

This means that all the good domain names are being registered as we speak. Chances are that someone may register a domain name that you’re thinking of, so it’s smart to register a domain name as soon as you think of an idea.

This is why all smart entrepreneurs proactively register domain names even before launching a business.

Domain names are cheap, and you can register them for a year. If you decide to not pursue the online business idea, then you can let them expire.

The bottom line is, if you are serious about building a business, then you should register a domain name right away.

It will help you protect your brand’s identity, business name, and even future business ideas.

How to Choose The Best Domain Name?

Domain names play a very important role in your website’s identity and success. This is why it’s important for you to carefully think about the domain name you choose.

However, it’s also important to not overthink it otherwise you will never get past the research phase.

Following are some general tips to keep in mind when searching for a domain name.

Make sure that your domain name is easy to pronounce, spell, and as short as possible.
Stick with the .com extension because most users find them easier to remember than any other domain extensions.
Use your keywords and brand name in the domain name search. For example, is more search engine friendly, than
Do not use numbers or hyphens in your domain name. It makes them harder to pronounce and difficult to remember.

How to Register a Domain Name (Step by Step)

You can register a domain name from any of the top domain registrars that are authorized by ICANN to register domain names.

Since there are so many different registrars, we will cover the three most popular ways to register a domain name, and you can choose the one that best fits your need.

What Is a Petabyte?

The next storage unit to consider is what’s known as a petabyte.

The prefix “peta” is the measurement unit for one quadrillion, or 10 to the power of 15.

Since this is 1,000 units of one trillion (tera), then one petabyte is equivalent to 1,024 terabytes. That’s one quadrillion bytes.

You would think this volume of information could never be used. However, there are petabytes of information flowing through computer systems and networks today, however hard that may be to believe.

But consider the following modern applications of petabyte sized technology:

Google processes over 24 petabytes of information every day.
Mobile phone networks transmit over 20 petabytes to and from users every day.
The Blue Waters supercomputer has over 500 petabytes of tape storage.
The United States Library of Congress contains over 7 petabytes of digital data in its archives.
World of Warcraft servers require over 1.5 petabytes of storage to run its online game.

The scale of a petabyte is hard to wrap your head around, but once you consider the scenarios above, it becomes quite clear just how much data is involved.

A single petabyte could store over 10,000 hours of television programming. If you filled an entire four-drawer filing cabinet with documents filled with text, you could fit 20 million of those file cabinets into a petabyte.

In fact, you could store every single written manuscript created by humanity since the beginning of recorded history in 50 petabytes.

That’s a lot of data.
Understanding Memory Terminology

It’s important to understand the units of memory because it’s used everywhere where there’s technology these days. Any time you buy a computer, a mobile phone, or a tablet, the specifications are all written in terms of memory storage, and how much data the technology can transmit.

If you understand all these terms, then you’ll know just how much better one computer is than other. You’ll appreciate how much better a 4G mobile network is than a 3G one. You’ll appreciate how much more you’ll be able to store on a 1 terabyte memory card rather than a 500 megabyte one.

As technology continues to advance, it’s possible there will be new units of memory to learn about. But for now, these terms are all you’ll need to know.

And if you’ve gotten this far, you should jump over to an article we’ve written about understanding network transfer speeds, which consists of megabits per second, gigabits per second, etc. This will help you understand when your ISP tells you that your download speed is 15 MBps. Enjoy!

YouTube rolls out a short-video ad tool for small businesses

YouTube is introducing a new tool that would allow small business owners to create video ads in the least possible cost. The tool is fairly easy to use and doesn’t require any technical or creative know-how.

Titled as the YouTube Video Builder, the tool went for a testing phase with a small group of users and is now being rolled out to the general public. According to Ali Miller Director, Product Management, YouTube Ads, the video builder will specifically help small businesses during the pandemic when the need to release videos quickly is apparent.

Business owners who wish to access this tool can log on to the service via their Google account. They can also link their non-Google email address to avail the service. Businesses will also need to have their own YouTube channel to upload videos.

The operations of the YouTube video builder is simple. Advertisers can utilize images, text, and photos from their business’s profile and customize the layout, colors, and fonts as per the preference. The video can be either six-second or 15-second long and will be uploaded as Unlisted on the company’s channel.

The company can also share the video on social media and/or embed it with other websites. And if they wish, they can run the videos on ads through Google Ads.

Similar to YouTube, Vimeo also released a tool to aid small business owners to create professional-looking social videos in February. Last fall, Facetuner maker Lightricks also launched a line of apps that would be helpful for small businesses in their social media marketing campaigns.

Facebook Friendships Could Be Used To Determine Covid-19 Spread

The coronavirus might just be the single biggest threat that humanity has ever faced, and that truly is saying something. We need to get ahead of it and a big part of the reason why that is the case has to do with the fact that if humanity fails to flatten the curve then it could potentially cause a lot of problems that would include us being set back quite a bit in terms of economic growth as well as technological progress.

One of the best ways to ensure that everything works in your favor is by looking into tracking the spread of the virus, and it turns out that Facebook might just be quite good at doing this sort of thing all in all. The reason behind this is that the social media platform, with its Social Connectedness Index, can make it quite clear who people are quite connected to, and this makes it a lot easier to track who might have been exposed to the virus and who needs to be quarantined for their own safety as well as the safety of others.

If someone is diagnosed with COVID-19, their friends list can be used to see who they might have met and thus who might have been exposed to the virus. This will make it a great deal easier for the necessary precautions to be taken, and a lot more can be done in order to make the most of things like this all in all. This is just one example of how technology can make it a great deal easier for this virus to be handled adequately, and in a lot of ways these are things that matter a lot more than you would have initially realized. Facebook’s help in this regard could be a game changer for key players in the fight against coronavirus.

WhatsApp Limits The Forwarding Of A Message To Only One Person At A Time

WhatsApp Limits The Forwarding Of A Message To Only One Person At A Time To Slow Down The Spread Of Misinformation

  • The platform announced to put new limits to forwarded messages after a mass increase in the spread of the coronavirus misinformation.
  • Previously, you could forward a single message to up to 256 users at a time, but the company has been putting limits on this feature over time.
  • WhatsApp experiencing surged traffic during these days could potentially help the misinformation to spread even more and here are the steps the company is taking to curb the spread of this misinformation.

Whatapp announced to put a limit on the forwarding of the messages on Tuesday after there was an increased forwarding of the messages containing the coronavirus misinformation. If a message has been forwarded by a chain of 5 users, it will be identified as a ‘highly forwarded’ message by the company’s server and then the user will only be able to forward this message to only one person. The new policy will be implemented moving forward and aims to create friction to lower the speed with which data moves across the platform.

The Facebook-owned company stated in its blog post that they know their users forward messages containing useful information, memes, entertainment content, or meaningful prayers and quotes. The users have also organized public moments in recent weeks to support the frontline health officials who are combating the coronavirus. But the platform stated that they have also seen a huge rise in the distribution of coronavirus fake news and it is important to slow down its speed so the platform will continue to be a better place of private discussion for the users.

Earlier, it was easy for the users to forward a message to up to 256 people with only a few taps and these messages also not indicated to be forwarded. It was almost unattainable for the platform to induce who might be spreading hate speech across the platform due to the end-to-end encryption in WhatsApp. This issue once was the reason for a crisis in India in which the said platform was linked to anarchy.

The platform tested to put a limit on the number of times a message could be forwarded for the first time in 2018. The company placed two arrows to indicate a message was forwarded and the platform reduced the number of people a message could be forward down to 5 users in 2019 which is now dragged down to only one user.

This soft limit still allows you to forward a message to as many people as you want to but you will have to send the message over and over again to different contacts on your WhatsApp. According to the company, this friction is an effective measure to reduce the speed with which the messages spread across the platform and there was a decrease of 25% in the forward globally during the last year.

Several studies and news publications have raised their concerns regarding fake news on Whatsapp and it appears the Facebook-owned app has started to listen to some of its critics. Recently, Whatsapp integrated a search button to cross check the content of a message in Google search, the messaging platform also facilitated a bot that provides verified information about COVID-19 and donated $1 million to the IFCN, which are indeed a good small step towards fact-checking content from the web. Yet, Whatsapp needs to implement better and more smart content moderation strategies to effectively deal with the misinformation propaganda.
