Silicon Valley was mourning a pioneer-

ing computer scientist whose accom-

plishments included inventing the widely

relied on "cut, copy and paste" com-

mand.

Bronx-born Lawrence "Larry" Tesler,

former Xerox researcher died this week

at the age of 74.

"The inventor of cut/copy & paste, find &

replace and more was former Xerox

researcher Larry Tesler," the company

tweeted.

A graduate of Stanford University, Tes-

ler specialised in human–computer in-

teraction, employing his skills at Ama-

zon, Apple, Yahoo and the Xerox Palo

Alto Research Center (PARC).

The cut and paste command was re-

portedly inspired by old time editing that

involved actually cutting portions of

printed text and affixing them elsewhere

with adhesive.

"Tesler created the idea of 'cut, copy, &

paste' and combined computer science

training with a counterculture vision that

computers should be for everyone," the

Computer History Museum in Silicon

Valley tweeted.

The command was made popular by

Apple after being incorporated in soft-

ware on the Lisa computer in 1983 and

the original Macintosh that debuted the

next year.

Tesler worked for Apple in 1980 after

being recruited away from Xerox by late

co-founder Steve Jobs.

Tesler spent 17 years at Apple, rising to

chief scientist.

He went on to establish an education

startup and did stints in user-experience

technology at Amazon and Yahoo.

THIS IS HOW PAYPAL USES AI/ML TO MANAGE $712 BILLION PAYMENTS

W ith the government bringing up a startup-like approach for the e-commerce system in India, the industry has been steadily on an

upward trajectory. Although 80% of the transactions have still been in cash, in 2020, UPI has shown promising growth by reaching

1.3 billion in transactions and a 7% growth in the value of transactions to ₹2.16 trillion. And PayPal has been a significant player in this cut-

throat market with approximately more than 33.8 million transactions per day and $22,577 payments every second. Not only that, at the end

of 2019, PayPal had a total of 305 million active accounts with a total payment volume of $712 billion.

With the increasing use of mobile phones and simple payment methods, India has a lot of potential when it comes to the digital economy.

PayPal is planning on capitalising it and replicating their global vision of democratising financial services.

Leveraging AI and ML technologies in areas like risk, marketing, customer service, PayPal is continuously looking towards pushing the

boundaries in the payments market.

The TechStack

For the tech stack, PayPal runs one of the most massive hybrid-cloud environments in the world. It hosts multiple technologies in each lay-

er and function. Around 2700 applications are running over 20000 servers with 238 PetaBytes of storage.

They use relational and non-relationship databases like RDBMSs Oracle Parallel Server, MySQL, NoSQL, Couchbase, MongoDB and Cas-

sandra. Besides, for big data and analytics PayPal uses Hadoop, Apache Spark, Elastic Search, Druid and Teradata.

For the frontend, it leverages React, Node.js/kraken framework with Javascript programming. The backend tech stack is primarily based on

Java with Springboot framework and REST, with other options being Go and Scala+Akka.

How PayPal uses AI and ML

Just like traditional financial institutions, PayPal used logistic regression for fraud detection. However, now it leverages advanced tech-

niques like gradient boosted trees (GBTs) to improve its accuracy of ML models.

Recently, it has started to turn to more advanced AI tech like deep learning, active learning and transfer learning with their ‘Risk AI’ journey.

As a result, it has been continually achieving 10-20% more accuracy over other traditional ML approaches in real time fraud detection.

PayPal also helps its employees get familiar and learn new technologies like AI, ML and blockchain, along with advanced courses on lan-

guages to build their stack team towards the area of AI.

Hiring Talents

PayPal has its largest technology centre in India apart from the US and is on a constant lookout for top talents when it comes to software

developers, architects, user experience engineers, web developers, data scientists, analyst and operations among several other positions.

PayPal hires both laterally and from Universities.

In the last few years, their key addition for upskilling and research is the ‘Innovation Lab’ it opened in Chennai and Bangalore. These labs

support projects in sectors like machine learning, artificial intelligence and IoT, among others. Employees can build projects on their con-

cepts or ‘proofs’ on their concepts before taking it to the leadership.

AI-POWERED ROBOTS ARE NOW TEACHING IN BENGALURU SCHOOL

I n an unprecedented event, Indus International School has deployed AI-powered robots - Eagle, Eagle 1.0, Eagle 2.0 to teach in class-

Using Mobile Internet While Phone Is On

Airplane Mode

Do you know how to use your mobile internet while the

mobile is on flight/airplane mode? When one’s phone

is on flight mode it prevents the user from making or

receiving any calls, while also preventing the user

from using the internet. However, since internet is now

a basic requirement, we will tell you how to use it on

your phone even when the latter is on flight/airplane

mode.

The user will first need to dial a number using their

mobile phone. They can then use the internet after

turning on a specific setting. Check out the steps given

below:

• First, switch to the flight mode setting on your an-

droid mobile phone.

• After this, dial (* # * # 4636 # * # *)

• As soon as you dial this number, you will see three

options on the screen.

• Phone information1, Phone information2, Wifi infor-

mation.

• If your phone has SIM card number 1 with internet

data, then tap on phone information 1, otherwise,

click on phone information 2.

• A new page will open up, where you will find that

the button opposite the mobile radio power is

switched off. Turn it on.

• You will see a button at the bottom. Clicking on it

will throw up some options, including one to enable

data connection.

• By clicking on it, the internet will start on your mo-

bile.

Note: This method of using mobile internet on airplane

mode can only be applied to android mobile phones.

Gmail gets a brilliant new feature that will make it easier to find what you’re looking for

W e have all been there looking for a critical piece of information that we know is buried in somewhere in our inbox.

The email hasn’t been deleted but that doesn’t mean we’ll find it on the first try. Your inbox may be packed with

emails that have some of the same search terms, complicating matters further. That’s all the more surprising when it happens

in Gmail, considering that Search is Google’s most important product.

Google is apparently aware that Gmail needs better search functionality and it has

devised an update to make hunting for important data a lot faster than it was previ-

ously.

The new Gmail search is getting so-called search chips, which should make it

even easier to sort emails and filter results to find the emails you need. “For exam-

ple, you can search a colleague’s name and further narrow your results by select-

ing search chips like attachment type (Text document, Spreadsheet, PDF) or a

specific timeframe. You can also filter out certain results, like calendar invites,”

Google explained in a blog post.

To get the filters, you should just load up Gmail as you usually do and wait for your

corner of the world to get the update. G Suite users should be the first ones to no-

tice the update but it will eventually reach all Gmail consumer accounts. It is unclear when the Gmail mobile apps will get the

feature, however.

Facebook Quietly Releases Pinterest Clone

App - 'Hobbi'

Social media giant Facebook has quietly released a

new app like Pinterest called 'Hobbi', a photo and vid-

eo sharing app designed for documenting users hob-

bies.

The app is available for iPhone users and it was cre-

ated by New Product Experimentation (NPE) a team

within Facebook tasked with experimenting new prod-

ucts and services.

According to its page in the App Store, in this photo-

sharing app one can capture and organise their crea-

tive process like cooking, baking, arts and crafts, fit-

ness or home decor.

The app is currently available in 84 countries, includ-

ing the US, Australia as well as Canada, according to

Sensor Tower and has fewer than 5,000 downloads.

Facebook so far has launched just a handful of NPE

Team-branded apps. Last year, it launched a chat app

for making friends called Bump and a social music

app Aux.

Additionally, a meme editor called Whale, has already

shut down.

Adobe Photoshop gets new features for the desktop and iPad on its 30th birthday

D ark UI support arrives for macOS Catalina, iPad app receives Object Selection and better typography controls of the

desktop counterpart

In a nutshell: As is usually the case with birthdays, Photoshop also put on some weight after turning 30, albeit in the shape of

several new feature updates and performance improvements across its desktop and iPad apps.

Photoshop, a byword for image editing and manipulation, crossed its 30th birthday recently. Although the software has faced

stiff competition from several paid and free programs over the years, it continues to be one of the most feature-rich and com-

plete products on the market today.

Adobe celebrated the milestone with a blog post announcing several new features for desktop and iPad users of Photoshop,

starting with an enhanced Content-Aware Fill (CAF) workspace on PCs that allows for iteratively selecting and filling multiple

areas of an image without having to leave the workspace window.

The next major feature for desktops is an improved Lens Blur filter that now uses the GPU to achieve a more realistic bokeh

look for images. The updated algorithm is also able to generate blurrier edges on objects in front of the focal plane and can

provide more colorful specular highlights in photos.

Users running macOS Catalina can now soothe their eyes with a dark mode for Photoshop that should blend nicely with the

rest of the OS. There's also a few under the hood changes to make the UI more responsive to mouse and stylus movements

with smoother panning, dragging and zooming. For those on Windows, the latest Photoshop update removes the need for

WinTab drivers, mostly used by artists for supporting styluses or digitizer tablets.

Photoshop's iPad app continues to catch up with the desktop version and receives the latter's Object Selection tool for quickly

selecting and isolating items of interest in an image. There are also new type settings, including layer, character and options

properties that enable text tracking, leading, scaling and formatting (caps, strikethrough, subscript, etc.) with kerning to arrive

in a future release.

Adobe's launch of Photoshop for iPad wasn't well-received initially due to a lack of features but the company has put out mul-

tiple releases in a span of three months to close the gap with its desktop counterpart and is shipping new capabilities "as

soon as the user experience has been adapted to the iPad and reimagined to take advantage of touch and mobility."

These latest updates should also help with improving file uploading and downloading speeds over the cloud, which Adobe

says could end up being up to 90% faster, depending on file size and network performance.

T he Internet of Things (IoT) is starting to transform how we live our lives but all of the added convenience and in-

creased efficiency comes at a cost.

The IoT is generating an unprecedented amount of data, which in turn puts a tremendous strain on the Internet infrastructure.

As a result, companies are working to find ways to alleviate that pressure and solve the data problem.

Cloud computing will be a major part of that, especially by making all of the connected devices work together. But there are

some significant differences between cloud computing and the Internet of Things that will play out in the coming years as we

generate more and more data.

Difference Between Cloud Computing and IoT

Cloud computing, often called simply "the cloud," involves delivering data, applications, photos, videos and more over the

Internet to data centers. IBM has helpfully broken down cloud computing into six different categories:

Software as a service (SaaS): Cloud-based applications run on computers off site (or "in the cloud"). Other people or com-

panies own and operate these devices, which connect to users' computers, typically through a web browser.

Platform as a service (PaaS): Here, the cloud houses everything necessary to build and deliver cloud-based applications.

This removes the need to purchase and maintain hardware, software, hosting and more.

Infrastructure as a service (IaaS): IaaS provides companies with servers, storage, networking and data centers on a per-

use basis.

Public Cloud: Companies own and operate these spaces and provide quick access to users over a public network.

Private Cloud: Similar to a public cloud, except only one entity (user organization, company, etc.) has access.

Hybrid Cloud: Takes the foundation of a private cloud but provides public cloud access.

The Internet of Things, meanwhile, refers to the connection of devices (other than the usual examples such as computers

and smartphones) to the Internet. Cars, kitchen appliances and even heart monitors can all be connected through the IoT.

And as the Internet of Things surges in the coming years, more devices will join that list.

The Internet of Things and cloud computing are different but each will have their own job in tackling this new world of data.

Role of Cloud Computing in the Internet of Things

Cloud computing and the IoT both serve to increase efficiency in our everyday tasks and the two have a complimentary rela-

tionship. The IoT generates massive amounts of data and cloud computing provides a pathway for that data to travel to its

destination.

Amazon Web Services, one of several IoT cloud platforms at work today, points out six advantages and benefits of cloud

computing:

• Variable expense allows you to only pay for the computing resources you use and not more.

• Providers such as AWS can achieve greater economies of scale, which reduce costs for customers.

• You no longer need to guess your infrastructure capacity needs.

• Cloud computing increases speed and agility in making resources available to developers.

• You can save money on operating data centers.

• You can deploy your applications worldwide in a matter of minutes.

Much More to Learn

The Internet of Things (IoT) is powering transformation for enterprises, consumers and governments. Emerging tools and

technologies like smart speakers, machine learning and 5G are enabling huge gains to efficiency and more control at home

and in the workplace.

The continued growth of the IoT industry is going to be a transformative force across all organizations. By integrating all of

our modern day devices with internet connectivity, the IoT market is on pace to grow to over $3 trillion annually by 2026.

Business Insider Intelligence, Business Insider's premium research service, is keeping its finger on the pulse of this ongoing

revolution by conducting our third annual Global IoT Executive Survey, which provides us with critical insights on the most

pivotal new developments within the IoT and explains how top-level perspectives are changing year to year. Our survey in-

cludes nearly 400 responses from key executives around the world, including C-suite and director-level respondents.

Through this exclusive study and in-depth research into the field, Business Insider Intelligence details the components that

make up the IoT ecosystem. We size the IoT market and use exclusive data to identify key trends in the connected devices

sector. And we profile the enterprise, governmental and consumer IoT segments individually, drilling down into the drivers

and characteristics that are shaping each market.

The top Apple news stories

March 30 could be launch for new cheap iPhones:

According to a German tech site, Apple could unveil

the iPhone 9 (or iPhones SE 2) on March 30. The de-

vices could then appear on store shelves on April 3.

As previously reported, the iPhone 9 could start as low

as $399.

“iPhone 9” leaks, likely is a fake: Speaking of the

iPhone 9, a supposed “real life” version of the phone

leaked on TikTok (mirrored on Twitter). However, it is

very likely this is just a modded iPhone 8 as the de-

sign does not match up with the leaks we have seen

for the device thus far.

iPad Pro refresh could land in March, too: Along

with that new low-cost iPhone, Apple could also unveil

the refresh of the iPad Pro in March. This iPad could

have a similar triple-lens rear camera module as we

saw on the iPhone 11 Pro.

5G iPhones could have Apple antennas: According

to a report from Fast Company, the antenna modules

that will appear in the first 5G-enabled iPhones could

be produced by Apple itself. Allegedly, Apple was dis-

satisfied with Qualcomm’s antennas, which is what

spurred the manufacturing change.

Apple could allow different default apps, finally:

You can use Chrome on an iPhone but you can’t set it

as the default browser, as that’s locked to Safari. How-

ever, according to a rumor, Apple could finally let peo-

ple customize the default apps on their iPhones. We’ll

believe it when we see it.

Coronavirus will likely impact Apple’s bottom line:

Apple issued out a notice to investors that its quarterly

revenue will likely not meet its previously stated goals

due to complications resulting from the outbreak of the

coronavirus. Around the world, many Apple stores

have been closed for weeks.

Unlock your car with your iPhone or Apple Watch:

Apple could be working on a new “CarKey” feature

that would allow you to use your Apple hardware to

unlock your NFC-capable car. What’s more, you could

actually share your “keys” with other people’s iPhones,

digitally. It’s the future!

SONY SMARTPHONE DIVISION STILL IN CRISIS, SONYMOBILE WEBSITE RETIRED

S ony continues to carry out the work of reorganization of its mobile division, after the difficulties encountered during 2019

which marked one of the lowest points for the Japanese company, which in three months (July, August and September)

managed to sell only 600,000 Xperia smartphones (900,000 in Q1 2019).

This reorganization program includes the recent closure of Sonymobile website, the site which for over 10 years has been the

reference point – as well as the home – for all the Japanese manufacturer’s smartphones. Anyone who tries to access it will

be automatically redirected to Sony.com, in which the smartphone section is now accessible by following the Prod-

ucts>Smartphone tab.

Sony confirmed already at the end of 2019 that it would reduce the resources of the mobile division invested in Europe, while

adding that the marketing of smartphones would not have been in question.

Microsoft's all-in-one Office app with Word, Excel,

PowerPoint now on iOS: Check features

• The new Office app requires far less phone storage

than installing individual apps

• Microsoft also mentioned three new features that

will be rolled out on both Android and iOS devices

really soon

After launching the all-in-one Office application solely

for Android smartphones that would combine Word,

Excel and PowerPoint under one roof, Microsoft has

now made it available on iOS phones as well.

Earlier, Microsoft has launched an all-in-one Office

application on Android smartphones in order to help

its users to streamline all their document formats by

putting all three apps -Word, Excel and PowerPoint -

under one roof. The new app is available for down-

load on iOS devices directly through the Apple App

Store and on Google Play Store for Android users.

Earlier, the app was released for testing purposes

through a public preview in November.

Combining all the three apps together will simplify the

experience of users who are always struggling be-

tween switching from one app to another for their doc-

ument needs. Moreover, the single app requires far

less phone storage than installing individual apps.

If you are using a Windows computer with a standard hard drive, sooner or later the computer will become sluggish. One way

out is to tweak Windows to perform better with your existing hardware.

We own multiple devices today but most of us don't use them to their full potential. Here are tips to improve and enhance the

functionality of your devices.

Make your TV smart

There are a few options available in the market to add smarts to any television. You can either go for an HDMI dongle style

device that can be easily hidden behind the TV (Amazon Fire Stick, Google Chromecast) or get a large box-style device

(Apple TV, ACT Stream TV, mini PC).

Either options will give you the control for screen resolution up to 4k and we recommend opting for one that gives you 4k res-

olution to be future-ready. In case you already have a Smart TV from a reputed brand, then you don’t need to get an extra

device. However, most small or unknown brands tend to load an older version of Android and that too half the time without

access to the app store. In such cases, it's best to go for a third-party device for better performance and more app options.

Add voice assistant to any speaker

Voice assistant speakers such as Amazon Echo and Google Home are great to use as the louder volume make them easy to

operate and interact. But what if you already own a great speaker set up? In that case, you can add the Amazon Alexa voice

assistant to a speaker via the Amazon Echo Input. This sleek device can be easily hidden yet offer 3.5mm audio out, Blue-

tooth, WiFi, etc. In case you want to add Alexa to your automobile speaker, then you will need to invest in Echo Auto. Echo

Auto is powered by the car’s cigarette socket and connects to the car’s stereo via Bluetooth or aux port.

Speed up your Windows computer

If you are using a Windows computer with a standard hard drive, sooner or later the computer will become sluggish. One way

to solve this issue is to upgrade to the expensive SSD storage. The other way out is to tweak Windows to perform better with

your existing hardware. This can be done by enabling performance mode. Open properties of My computer and click on Ad-

vanced system settings option. In the box that opens up, click on settings for Performance and choose “Adjust for best perfor-

mance”. This would disable all animations and optimise display settings, meaning improvement in day to day usage.

Check your smartphone’s performance

If you own an Android smartphone, chances are that you would have noticed it getting sluggish, not registering touch or drop

WiFi connection among other issues. How do you find out the issue plaguing your smartphone in such a case? Simple. Use a

diagnostic app such as Test your Android or Phone Doctor Plus. These apps give you the option to check various compo-

nents and sensors of your smartphone making it easier to identify any issues. This is also handy to check performance when

you are purchasing a second-hand phone.

List Of Five Best Safety Gadgets And Apps

For Women Safety

Technology is playing a major role when it comes to

safety especially when it comes to a women safety

issue in our country. Many companies came up with

new technologies which can help women keeping

themself safe. There is apps, wearable devices, GPS

trackers and many others. This article includes a list of

apps and gadgets which will act as a security guard

for the woman and protecting her in the worst-case

scenario.

bSafe

bSafe is a personal safety app which creates a ‘social

safety network' of individuals who gets a notification in

case of an emergency or in situations where the user

feels unsafe. The app provides an alarm which sends

the exact location and audio-video of the surrounding

areas to the contact previously selected the user. The

app sets a timer that will automatically send an alarm

to friends if the user fails to return in time to turn off

the alarm. It is also capable of initiating a fake call into

their phone if they want an interruption.

My safety Pin

SafetyPin app works like a secure guide which will

suggest users take the best and safest route. While

reaching an unsafe location, the app sends alerts to

the user and you can invite family or friends to track

you. This app discriminates the safety of an area using

various parameters like public transport, visibility, se-

curity and more.

Letstrack

Letstrack is a vehicle security system along with an

app. Users can equip this device on their vehicle and

connect it with their smartphone. Letstrack offering

features like connectivity in rural areas, real-time

tracking, 24-hour history, provide zone alerts and the

most important SOS alarm.

Safelet

It is a wearable device which comes with two buttons

on the side that can be used to send a message or

contact friends and family. Besides, it also syncs with

the user's smartphone to start audio recording. In case

of an unsafe situation, the concerned member who

receives the alert can immediately dial the emergency

number available within the app.

Eyewatch SOS for Women

The smartphone app is capable of capturing audio

and video of the user's surroundings and sends it to

the registered contacts along with an alert message.

HOW TO LEARN A PROGRAMMING LANGUAGE AS FAST AS POSSIBLE

W hether it is for a newly emerging language like Dart, Swift or some of the most established ones like Python, R, etc.,

the process of learning a new programming language is daunting. People want to learn a programming language

as fast as possible. However, learning a programming language quickly doesn’t mean that there are underlying shortcuts; you

still have to practice a lot.

Below are given step-by-step tips to help you overcome the learning curve of a new programming language :

Research the Important Concepts : The first thing to do before learning a new programming language is to get a short in-

troduction on it. As you will be going fast and have no time to rethink about it, the first and foremost thing to do is get accli-

mated with what you would like to do with the language and what the programming language is capable of doing. Also, the

various opportunities it produces in terms of the job scenario and the type of work you intend to do with it.

Next is to figure out what kind of resources you are comfortable with to learn these concepts. Some prefer their own unique

style with all the sticky notes and creating mind maps, some prefer reading the books, some prefer learning through video

and some learn from just diving right into it. So, when you figure out what ‘type’ of learning you are comfortable with, collect

resources according to it. However, one can also learn by mixing all types of resources.

First The Language, Then Comes The Rest : People often make the mistake of trying to get the hang of different libraries

first but that often results in a lot of time getting wasted. First, get familiar with the language, then go for the frameworks.

Practice The Language : The concepts that you have learned earlier are still fresh and have not been internalised in your

memory; the best way to make the concepts a part of your memory is to practice them. This enables the essential program-

ming concepts to get installed inside your brain for the long run. Rather than going around each concept of the programming

language and wasting time, learn the important concepts first. You can learn other things while practising on websites such

as LeetCode, HackerRank, CodeChef and CoderByte, to test your concepts.

Use Code Reviewing Sites : Now that you have learned some programming and because you are still new to the language,

you will need someone to review your code. Reviewing can mean someone suggesting you alternative ways of carrying tasks

like opening, closing and mapping in a more straightforward manner using zip or list or other suggestion to make your algo-

rithm more efficient. There are numerous websites like StackExchange, which offers CodeReview on their network that is

used solely to ask a review on your code.

Going Through Codes, A Lot Of Them : There is only one place where you should go to get production codes for the lan-

guage you are learning and that is Github. Production code is a tested and stable code that has no chance of crashing and is

made for real-life implementation, so the more you look at these kinds of codes, the more your language will get refined.

Build Projects : What better way to learn and get some confidence in your programming skills than building some projects.

Like, if one has chosen data science, try analysing a dataset trying different algorithms.

Try starting from simple projects. For example, for Python, there are basic projects like number guessing, dice rolling simula-

tor, e-mail slicer etc. For SQL start from something fun like creating a database of your friends and their details

Outlook : Learning a programming language is not easy and it depends on your previous knowledge. But, it also varies de-

pending on how fast you can learn and how much you practice. So, you need to figure out how many hours you need to put in

a day, based on the skills you already have to cut down the learning time in terms of months.
