How to unsend WhatsApp messages | Revert back message sent by you | Delete your message in your friends chat

There were many people who were always downloading skinned version of WhatsApp like GB WhatsApp, etc even after Lot of cautions about privacy

Most people were downloading GB WhatsApp only because they could revert back the messages they have sent

Now you don't have to download these skinned versions because WhatsApp Inc has given this feature in there new update

Now send any message in group are one-one chat, select it and press delete. Now you'll have 3 options delete for me, cancel and delete for everyone.

How are Vehicle Price is Fixed | Vehicle Charges Breakup On-road, Ex-Showroom, etc

First of all, Dealers are separate bodies who are just registered with the manufacturers to sell there products on dealers showrooms. Dealers buy from the factory and sell the vehicle to there customers adding there expenses and profits

Now Lets breakup vehicle prices

Ex-Showroom Price :

Dealers buy vehicles from factory at Ex-Factory price, when the trucks reaches the showroom, the price including Ex-Factory price, Transportation, Dealers margin, etc is called Ex-showroom price.

Handling/Logistics/Parking charges :

These charges are not included in every showroom but mostly on Metro cities & few Major cities these charges are also added. Now the price of vehicle is Ex-Showroom + Handling/Logistics/Parking charges.

Insurance :

In India, we have a rule that when a vehicle rolls out of the showroom it should be covered by Insurance. So add Insurance price to the above price.

But it is not mandatory to take Insurance policy in the showroom, you can take the policy from whichever place you like but vehicle should be covered with Insurance before leaving showroom and it should be of 1 year at least.

TCS (Tax Collection at Source) :

You need to pay TCS of 1%, if the vehicle's Ex-Showroom price is more than 10 Lakh Rupees. But it is refundable if you file IT returns.

RTO/Registration Charges :

Like Insurance it is mandatory for a vehicle to be registered before it leaves the showroom. Basically there are two types of registration

i) Temporary  Registration : It is registration for one month & after this period, registration expires. If you are not registered within this period you are liable for fine on monthly basis.

This is used mainly when you need a special number and it is yet to come and you want to register that number when it comes or You have bought vehicle from a non-local showroom and you want to register your vehicle in your local RTO.

ii) Permanent Registration : This is Permanent registration number for the vehicle and is valid for life time.

Permanent registration charges varies from vehicle to vehicle and in few states from fuel types also.


Accessories/RSA/Extended Warranty :

These are completely non-mandatory, you can take your vehicle even without these

i) Accessories : These are add-ons to your vehicle which you can completely deny or negotiate or even get them for free.

ii) RSA(Road Side Assistance) : By the name itself you can understand what it is. But make sure your Insurance company is offering RSA or not because insurance companies offer RSA at much cheaper rates than the vehicle dealer and few times RSA is given for free for some period of time by the manufacturer itself.


I prefer to take this service if ytou are not familiar with any of the minor repair works and you travel solo especially cars.

iii) Extended Warranty : This is something the sales person insist you to take by telling false stories and illogical facts, Indians take there vehicles seriously hence they fall prey to the words of sales executive. This can also can be denied

So Your OnRoad Prices includes ExShowroom price, Handling/Parking price, Insurance price, TCS, RTO Charges and Accessories/RSA/Extended Warranty.

How to Send Scheduled WhatsApp message

If you are someone like me, who often forgets important dates and wants to wish people on there special days. It's preferred to schedule your message on WhatsApp.

Open the app, sign in to app. Select scheduling services you need like E-mail, WhatsApp message, FB post, etc.

To send scheduled massage

1. Open the app

Google drive is Shutting down!!?

Soon on your drive dashboard you'll be getting a pop-up saying "we are closing.........."

Actually, if you are some one who use drive a lot this is a nightmare come true.

Because the first thing that strikes your mind is what about my stored datas? Will it be gone?? What can/should do??

Relax, Logically Google drive is not shutting down , you can say it's Evlolving😉

The Google drive will soon be known as Backup & Sync.

Frankly I'm one of them who thought that Google drive is a bit sluggish in operation. So, in this iteration of Google drive, Backup & Sync it aims to provide seamless operation like it's biggest compitator DropBox.

Like DropBox, on Backup & Sync you'll be able to upload by using check boxes instead of old annoying alert boxes which makes it feel like it's sluggish..

Google has taken it's compitation seriously and brings you a killer plan with this make over that is unlimited Images, Audios and Videos Backup. Which was Free 15GB storage after 15GB it would be paid.

Coming to the already stored data it is literally untouched.

The offer of unlimited storage as a catch, the images are compressed if image size is more than 16MB like wise Videos are compressed if resolution of Video is more than 1080p to 1080p(Full HD), it may cause some discomfort with professional photographers and videographers who shoot in 4K but for a normal, plain, ordinary mobile photographers and videographers it's still a killer plan.

Another update with Backup & Sync is another service called File stream which is for those who used Google drive for sharing files and File stream is not a free service it comes for fair price(latest official update)

Send High Quality Images on WhatsApp without Loosing Image Quality

We use WhatsApp everyday and we often prefer sharing using WhatsApp itself. But sending Images always results in considerable quality depletion by WhatsApp to save data and make transferring faster.

What if, you need to share High Quality Images, the only option is to use E-mail service. By using this trick you can share High Quality image without loosing quality in WhatsApp itself. Just follow these steps

1. Open the WhatsApp chat/contact you want to share images with.

2. Click on attachments, instead of selecting gallery, select document, browse and send the image.

The images are sent in its original quality but aren't preview as a Image which is sent in normal procedure

Please share the post, it may help someone & Feel free to comment

How to Compress Large Files without Losing Quality

If you are someone like me who like to store lot of movies, then files sizes are your biggest concern.. Here is a truck I use to save lot of my movies by compressing them without compromising on the quality of that video.

Firstly download this free software (depending on your PC platform)

Once downloaded install the software.

How to use this software:

Actually, it's pretty simple

1. Open the software, click on source and select your file from the dialog box appeared.

2. Select the destination location.

3. Select output type as MP4.

4. Check mark Web Optimized (it's very important). It's the unique feature of this software.

5. Go to Video tab, select '20' on video quality (best for compromising without losing quality) you can vary according to your quality requirement.

6. Go to Audio tab, set bit rate of your wish (128 is good)

7. Preview, if you like the quality. Click on Start

It takes 3-5 mins depending on the quality.. Once finished open the file and compare the quality

How to Hide your files and folders without any Third Party App

Using third party app was always & is thread to security of your system. Yes, there are lot of third party app which are trust worthy but it's your files, trusting third party app is risky.

In fact it's so simple, you don't need to waste memory of your phone on such apps.

Steps for hiding files are:-

1. Open file manager, select folder of files which you want to hide.
2. Rename the folder with ' . '(full stop) at the beginning.

The files will be hidden and won't be visible in Galary

Steps for unhiding files are:-

1. Select the folder (if not found, find show hidden files option).
2. Rename & remove full stop at the beginning.

In third party apps if you turn on phone in safe mode then these apps don't work and files will be seen but folders hidden by this method won't be visible even in safe mode. In case, you delete the app by mistake, files will be gone. So, it's better to use this method to hide the files.

You can try to retrieve the files that were hidden by those app by using the unhide procedure

Income Tax Calculation and Tax Savings

Everyone wants to and needs to file taxes. The problem is there is lack of proper knowledge on how taxes are calculated

Basically, there are 4 slabs in Income tax. In a financial year, if your Taxable Income is
Up to Rs. 2.5 lakhs -- No tax
Rs. 2.5 lakhs - Rs. 5 lakhs -- 10%
Rs. 5 lakhs - Rs. 10 lakhs -- 20%
Above Rs. 10 lakhs -- 30%

You all know this very well, but there is a misconception

For example: If your yearly Income is Rs. 15 lakhs, then we assume that it is more than Rs. 10 lakhs so, 30% of Rs. 15 lakhs (Rs. 4.5 lakhs) is the tax payable. But, tax deduction doesn't work like that

Government takes
10% of 2.5 lakhs = 25,000
20% of 5 lakhs    = 1 lakh
30% of 5 lakhs    = 1.5 lakhs

So you have to pay 2.75 lakhs not 4.5 lakhs so you still have 12.25 lakhs to enjoy;)

But who want to give there hard earned money to the government. So, people prefer to do tax savings..

To do proper tax savings first you have to know about Taxable Income

Taxable Income=Total Income-Tax Deduction

The more Tax Deduction , less the Taxable Income. Tax Deduction can be done by investing in Tax Saving Investments like Insurance, PPF, Mutual funds,etc and make tax savings up to 1.5 lakhs (if your income is above 10 lakhs you save around 45,000 and if your income is below 10 lakhs you save about 30,000.. It may not seem as much but it's very good savings)

The Best and Common Tax Saving Investments are:

Public Provident Fund(PPF)
Mutual Funds/ELSS

PPF is risk free but returns are less
MF/ELSS has high returns and also highly risky

Different types of Number Plates Permitted by RTO in India

You know that recently, The Police Department gave a notice on number plates design and gave nominal fonts and design for number plates and few examples of defective number plates

So, I thought of telling you about different Patterns of number plates permitted by RTO in India

Basically there are 6 Patterns of Number plates

1. Black over White background : Private Vehicles

2. Black over Yellow background : Commercial Vehicles

3. Yellow over Black background : Commercial Self Drive Vehicles

4. White over Black background : Military Vehicles

5. White over Blue background : Foreign Diplomat's Vehicles

6  White over Red background : Demo/Test drive Vehicles

And we have one car in India which is not tagged with any of these Pattern or Numbers i.e The Car of President of India it only has Indian Emblem (Four Lions) on it

CAPTCHA | What?.. Where?.. Why?

I am sure you have encountered CAPTCHAs while filling forms, signing up, etc.. Ever wondered why is it for? If yes, i hope you have got the answer!

If you have not got the answer, here you go!!

CAPTCHA is the acronym for Completely Automated Public Turing test to tell Computers and Humans Apart, which means a test which seperates Humans and Computers automatically.

CAPTCHA is security measure against Bot attacks. It avoids scripts which performs automatic Sign-ups and form fill ups, which can overload Servers and Data Centers and make them vulnerable.

Imagine a hacker(script kiddler) or spammer who wants to open 1 Lakh Gmail accounts, without CAPTCHA he can do it in One hour( since computers are faster). With CAPTCHA his code cannot work because computer cannot think independently.

Turing Test is a process in which you Identify, if the user is a Human or a Computer. It includes test like Entering Text given in the box, Performing simple Calculation or Selecting pictures from grid which matches the question given. The basic Idea behind this test is the ability to think independently, which computer lacks.

Ideally, Turing test for Humans Should be easy i.e you can easily clear in one go.. But few times it is hard to perform it properly and we sometimes find it difficult so the average success rate for Humans is above 80% but success rate for Computers is less than 0.01%

Since, we humans fail to Complete the test successfully few times 'reCAPTCHA' - A Google Company, which gives free API for CAPTCHA for your site and Biggest CAPTCHA provider is all set to launch its Latest Version of CAPTCHA - Invisible reCAPTCHA

The new reCAPTCHA looks promising, lets hope for the best :)

What is UPI? | What are the uses? | Last Blog of the Year

From Last few day, You probably have heard about UPI.. If you have not heard it, i'm going to tell you about it  because coming days you will hear about it a lot. so firstly

What is UPI?

UPI is the short form for Unified Payment Interface, which can be used to transfer money from any of your Bank Accounts to anyone Instantly

Digital India is most aspired dream for modern day India.. Even though there are more smart phone users in India Mobile Banking as not been implemented as forcasted.. NEFT, IMPS have there own limitations. UPI will eliminate those.

UPI is the Idea of National Payment Corporation of India(NPCI) with support of RBI

NPCI is the institute currently maintaining ATM's and in-charge of Inter Bank Transfer.

How to Use UPI?

UPI is mainly concerned with mobile banking, so for the convenience all major Banks have UPI apps available on respective stores/market places. I strongly recommend to download these apps from stores itself.

Is there difference between NEFT, IMPS and UPI

Yes, there is.

• National Electronic Fund Transfer: To transfer amount you should add all bank details, get approved then you can transfer which also depends whether bank is open or closed. So it is very time consuming.

• IMmediate Payment Service: It is a very good services and gives faster transfer(almost immediate). But same as NEFT you have to enter all the credentials of others bank account and this is also used only for bank to bank transfer not other services

• Unified Payment service: This similar to IMPS but with more features. when you register for UPS you will get an ID which can be shared to others to get money transferred no need of account no, full name, IFSC code etc. the id is enough and fund transfer is immediate

What is the difference between Wallet and UPI?

the difference is very simple

you add money to the wallet through the bank account and use money through wallet and if you want that money back you need to transfer/withdraw to your bank account

in UPI the money is directly transferred from bank accounts.

Where UPI can be used?

 UPI can be used everywhere, from grocery stores to bill payment. You can send and recieve money instantly with any business/merchants/sellers

The transaction limit is 1 Lakh Rupees and transaction fees per transaction is 50paisa

currently this service is in starting pace and is currently used for Inter-bank or Intra-bank transfer only.. In coming days you can pay hotel bills, college fees, taxi fares instantly using UPI

This is an wonderful initiative for cashless India and Truely Digital India

What about the security?

After lot if news about Hacking this days. the first question is how is my money secure while I'm using very vulnerable device

It is maintained by NPCI so no fear about security, because it gives world class encryption

add-on to that you get strongest measure in cyber security Two-Factor Authentication(email verification and OTP verification)

The non-optimized Cell Phones Market of India

Hi!! Good Morning, Good Afternoon, Good Evening

" Now a days, Cell phone Manufacturers are manufacturing phones which are more powerful than Laptops Five Years ago" , This is what we feel when you see the advertisements of the Mobile Phones released recent years. But, is it really true??

The manufacturers advertise there product on one key feature like 3 GB RAM or 64 GB Internal storage but there are not depicting there bottlenecks(performance back loggers)

Imagine if an Olympic Sprinter is told to run continuously on rock paved road without shoes, can he run has intended.
or
If a Bugatti Veyron  is fitted with fuel injection system of a Maruti Suzuki 800, can it deliver the same performance.


Imagine a Big workstation and you are working, you can use workstation only till where your hands can reach beyond that point how much ever the workstation be it no use for you. Similarly the worksation is the RAM and person performing work is Android i.e. the android can not utilize that much of RAM. why do you need it.

so, for an optimized smart phone perfect balance between Processor, ROM an RAM is necessary. Which is hard to find in newer phones which are actually degrading Smart phones actual intended Performances.

so dive in and explore and find only few optimized smart phones available. I wish I could afford them.

What is VoLTE

As we changed from 2G, 3G we gave interest only on data speed, not on The quality of Calls which is the main concern of the Mobile phone and there was no major improvements on the call quality

But in recent days, we are seeing new advancement in call quality that is VoLTE

VoLTE means Voice over LTE or Voice over Long term Evolution  means  transmiting and recieving voice on a LTE network or 4g network

What was happening before VoLTE

For example, you were subscribed to 3G network, but when you call, the call was send by using smallest bandwidth given to you by the cellular network. due to this there was call drops was more, took more time toi connect, voice lagging and quality of voice was not good

But in VoLTE what happens is, when you call somebody, The voice goes in HD quality on LTE/4G network,means connection is ultra fast because network knows it is a VoLTE call and gives preference in the network to call, due to this delay in voice is reduced and call drops will be minimum and you will be able to listen HD quality crystal clear voice

Also, when you are using 2G or 3G when you make a call the cellular data disconnects and cellular data is resumed after the call is terminated after some time. The resume time in VoLTE is very less, say Instantaneously.

Requirements to make a VoLTE call

4G phone with VoLTE 'ENABLED' MoDem and 4G service Provider at both Called Party and Calling Party

How does Metal Detector work?

Now a day, there is now one how has not seen a Metal detector, there are present in every place where ever there is a chance of crowd, they are present in all those places. Either it may be Mall, Railway Station, Temples, etc. Ever thought how they function. No Right, so this blog is for ‘You’.

Firstly, there are different types of Metal detectors, Hand-Held Device, Gate Keeping Devices, Ground searching devices.

History of Metal detectors:

The Metal detectors were introduced/invented to search antique items and gold under the ground and later used by military for searching the hidden Land mines in war prone areas.

The size of the Machine Were Big and Bulky but Powerful and Efficient in their job. Later on, they came into security purposes with light, portable but less Powerful. (To compare, the bigger ones are able to detect even a small knife and a small pin which is at 4, The bigger ones was able to detect even a small knife and a small pin which is at 4 ft. below the ground. But, the lighter ones can detect a small knife at distance of 1 ft. but not a small pin.) So let’s see How they work

Functioning Principle of a Metal Detector:

 The main principle on which the Metal detector works is Based on Maxwell’s equations. He is the one who showed, the Omni present couples (Adarsha Dampatigalu) of the world- The electricity and The Magnetism by his equations.

In this world, where ever you see Electricity you see Magnetism and where ever you see Magnetism you see Electricity. This is the principle behind Motors and Generators, where you have electricity you produced magnetism and where you have magnetism you have electricity.

Working of Metal Detector:

There are two coils present in scanning area (whatever type of detectors it may be) transmitting coil and receiving coil. The Transmitter coil has Circuitry which converts the given voltage to magnetic field and conveys; The waves take elliptical path to receiver coil because of properties of magnetism.

If any Metallic object interferes the field, the electrons of the metal object changes there spins due to influence of the magnetic field radiated by transmitter coil.

Due to spins, there is disorientation. Due to disorientation there is electricity is generated. Since electricity is produced in metal, the metal radiates its magnetic field. So extra magnetic field is produced and it is received by the receiver coil.

There will be a Controller which measures the received magnetic field and compares with the transmitted magnetic field. According to the compared field the voltage is sent to the Buzzer Which Loudens or Softens the sound based on the voltage given. Hence when the detector is close to the Metal object or the metal object is big the sound of buzzer is loud.

This is how the Metal detector work. Hope You Have Understood. Don’t forget to comment, +1, recommend and feel free to share. But don’t copy.

And the scanner you see at the exit of shopping malls are not Metal detectors they are RFID scanner, to know more about that Follow my blog.

                USB On-The-Go, often abbreviated as USB OTG, is a Specification that allows USB devices to act as a host device, that allows other USB devices such as keyboard, mouse, flash drives, etc.

This was introduced in the year 2001.

Traditionally Mobile Devices could only have connected to a PC/MAC by USB data cable, but Mobile device can act as host using OTG

Uses of USB OTG:

·         Connect USB flash drive

This is the most widely used feature of an OTG. It is used to store extra/big files that you use occasionally. Hence storing the phone space for quick and efficient working of your phones. It can be used as alternative to cloud storage (non-cloud based storage)

·         Connect Keyboard and Mice

Yes, you are right. This is the second most used feature :D. You can directly connect your Keyboard or Mice for playing games or key board can be used for typing long text or Emails.

I’m a person who always gives first priority to the safety. Since, road accidents don’t happen only because of you fault, most of the cases it is some others fault and roads are filled with dumb riders and drivers.

If your riding with a helmet, it will save your head*, but in a crash the most injured and surely injured part is your palm and wrist. So riding with a glove is very important

Reasons for wearing gloves:

1.       Improved Grip and Control:

You know that being out on a bike can make you pretty sweaty – especially if it is one of those warm and humid days. And that means your hands are wet, too. Like clothes with wicking technology, a good pair of gloves will help keep your hands dry, which means that you can maintain a better grip on the handlebars.

The gloves also serve to trap the sweat that would otherwise be likely to drip into your shifters. And over time, moisture – and especially perspiration because of its high mineral content – can cause those components to deteriorate.

2.       Comfort and Protection for Skin:

If you’ve ever spent a couple of hours or more on a bike, you probably realized that, somewhat surprisingly, cycling can be pretty hard on your hands. From the constant pressure on your palms, to the wear on your fingers from running your shifters through the range of gears, it doesn’t take long for calluses or blisters to develop. A pair of bike gloves can give your skin the extra layer of protection you need to be comfortable, even on the longest ride.

3.       Shock Absorption:

You’ll notice that many pairs of gloves on the market today have some type of cushioning, such as gel padding, etc., built into the palms. The reason is that gloves with this padding serve a very useful function in absorbing shock from the road that would otherwise be transferred to the rider.

4.       Protection in Crash:

What do most people do as they start to fall? They put their hands out to try and catch themselves, to break their impact as they hit the ground. If you’ve ever fallen like this, you know that you can really tear up your palms when they go skidding across pavement or rocks.

               

5.       Warmth:

This provide warm sensation in cold winds or high altitude riding. This prevent tour hands from numbness.
