Progressive Web Apps

Leave a Comment
Progressive Web Apps or PWAs - are websites that you can run as apps on your computer, phone and tablet. They look and work, exactly like a normal app, but there's nothing to install - they run in their own browser-like window. Crucially, they're not dependent on an internet connection, so they work offline too.
      PWAs are potentially safer than a normal apps and programs because they don't need to be installed on your device - thereby eradicating the risk of accidentally downloading malware. They also take up less storage space, because most of the app's data is stored on a server rather than on your PC, phone or tablet. You never need to manually update a PWA - this is done automatically by the app's developer. And they always work on the same way, regardless of the operating system or type of device you're using. So, you could use the same apps on your PC, iPAD, or any other device that supports them.
          The idea behind web apps isn't new. Apple's iPhone used them extensively when it first launched. The 'progressive' part refers to newer web technologies they use to deliver a smooth, safe, more app-like experience. The three main technologies involved are Caches  API, Service workers(which caches data to allow the apps to work offline) and Web App Manifest (which stores other data about the app, such as its settings).
      HTTPS encryption, meanwhile, ensures that connections can't be intercepted. In practice, when you use a PWA, you shouldn't notice any difference compared with a normal app. You launch it by clicking or tapping a shortcut on your home screen or PC desktop. It then runs in its own window, and works as if it were installed on your device, with no delay, even if you have a weak Internet connection (or if you're offline). PWAs can provide notifications and carry out other background tasks, just like standard apps currently do.
       You can already run PWAs on many Android devices. Try them by going https://pwa.rocks (see main image) via Chrome on an Android phone or tablet and tapping one of the PWAs featured there, such as Offline Wikipedia. Flipboard and the mouth-watering Progressive Beer ("the Ultimate guide to beer all around the world").
Once the web page loads, tap the menu button (three dots), select 'Add to Home screen', then tap Add in the message that pops up - you should now find a shortcut to the PWA version of the site on your Home screen.

WhatsApp Group chats can be Hacked

1 comment
Researchers have revealed that WhatsApp group chats could be spied on despite the messaging app's famous end-to-end encryption.However, that's not necessarily a reason to panic.Anyone able to take control of the App's servers could join group chats without admin approval, the researchers noted but the app notifies everyone in agroup chat that someone has joined, so such spying won’t be very stealthy at all. Plus, the person  joining will only be able to see new messages, not scroll back and see your old posts

Such privacy issues are worth noting,even if they don’t impact most of us. This flaw won’t be a problem for most users, and exploiting it requires sophisticated skills or access to WhatsApp’s servers, meaning it could really only be used by  facebook, which owns the messaging app, or by governments demanding access.
Additionally, a user being targeted would be aware of it, - making the flaw rather less usefull or spying. Still, it’s a fact worth knowing if you are genuinely worried about being targeted by government – level authorities, and you may instead want to switch to a messaging app that’s even more securely locked down.Signal, for example, uses the same encryption system as WhatsApp, but with tighter security and it’s not owned by Facebook.
Indeed, Microsoft has just introduced end to end encryption into Skype using the Signal protocol, to bring it more closely in line with WhatsApp, Facebook Messenger and Google Allo.
Its good to have independent researchers poking and prodding messaging apps for security reasons but we need level headed reporting and responses to avoid unnecessary panic.WhatsApp security is not perfect because there is no such thing.Not every design decision is a flaw.

Its encryption and design make it a solid security choice for most of us look to chat over the internet, so there’s no urgent need to abandon it.

Padmavati(Padmavat) movie review

Leave a Comment
After watching Padmavat, Rajesh Joshi is reviewing the film.

In the film Padmavat, Sanjay Leela Bhansali's cinema's grandeur and flashes are present:

Thousands of cavalry soldiers falling on each other for the Negev and the shield-sword,

The artillery pulling elephant that fires fire in the dark battlefield of dust,

The threat of the battlefields echoed in the sky,

Settled Rajput and Sultanate Earning the Richest of Lots of Rupees in Crores,

And amazingly reliable music!

Seeing the preview of this film made for a few people in a Delhi theater, it was seen wearing three-D glasses as if you were a part and parcel of story incidents like an invisible character.

This is the style and technique of cinema of Bhansali. But if you want to understand the politics of Padmav, then you will see food scenes in it. These days, heroes and villains are being set up in India by eating habits.

Before breaking down on one side of the film in the dastardown, Alauddin Khilji sniffing like a hungry animal; On the other hand, sitting on the other side as calmly as a seeker, Padmavati, a fan, to his gentle but harsh husband, who is eating Satvik food,

Padmavati(Padmavat) movie review,padmavati review,padmavat film review,




Where did Padmavati come from?

'Standing out of Padmavati to tell Khilji's girlfriend'

On one hand, chewing chickpea roasted roasted big animals, cruel and chaotic Muslim invaders who have been deceitful on the back of their enemies, on the other hand, the Hindu Rajput king who dies die for his honor and commitment. Ratan Singh.

In the way the stereotyping of Muslims in the last three four years, Sanjay Leela Bhansali used the same stereotyping in his film.

They have shown Rajputs as the staunch heroes of the word and the Muslim invaders like the arrogant and the villainous villains. But these claims were reversed and Rajput himself was threatening to stop the film on the violence.

In which period Mohammed Akhlaq, Ashqul Khan and Junaid etc. were beaten to death due to being a Muslim, when the common Muslims were asked to clean Kashmiri, Pakistan, terrorism issues repeatedly, beard with a clean mustache The people are seen to be seen with suspicion, in which the film tells the story of the clash of Rajputs with the Khilji like demon.


In the scene before the film, wearing a heavy black turban, wearing a thick antama in the eyes, a huge face of Jalaluddin Khilji looks like an executioner chewing meat, appears on the screen.

In one corner of the hall, a whole big animal is rotated round the fire and roasted round it. There is a turban around Jalaluddin Khilji, with a mustache and a Muslim with bearded ten-twelve and court attendants. These Afghan robbers are celebrating their fate at Delhi.

In this way, a young man full of pride has tied the ostrich with big chains like a dog and brought it there. This is Jalaluddin Khilji's nephew Alauddin Khilji. His cousin had asked for an ostrich's wings from him, but he brought the whole ostrich so that his uncle could ask for his cousin's sister's hand in Jalaluddin. Because he wants to make every unsuitable thing his own.

Cartoon: Padmavati, Padman and Confucian

Attitude: Padmavati truth or fantasy?

The Padmavati princess of Sinhala Island (Sri Lanka) is such a beautiful beauty, that her father's guests fall in love with King Ratan Singh of Mewar and marry him. These Buddhist girls, who chant the cycle of 'Oon Mani Padme Hum', turn into such a Rajputani, which starts to tell the sword a bracelet of sarranta, and in the fire with hundreds of kshatriyas alive to perform the jawar at the end of the film. Jumps up.

In the center of the story, there is a loyal King Ratan Singh who is the king who gives Padmavati out of the country. This guru tells Alauddin Khilji about Padmavati's Husn.

To achieve Padmavati, Allauddin's forces put a circle around Chittorgarh. Allauddin Khilji arrives inside the fort on the pretext of surrender and tries to take a glimpse of Padmavati. On failure, Raja calls Rattan Singh as a guest in his house.

Film with 3D Technology

Now begins the iron collision phase with iron. Sanjay Leela Bhansali, who is known for his films, has also removed this magnificence in the battlefield.

3D technique is amazing that you stand yourself on the battlefield.

Thunderbolt goes along with the collision of the Rakhirs and the Swords; The story of Rajputi on-Ban-Shan - Rajput can cut his head but can not bow.

Rajput is ready to put everything on his own to fulfill his promise.

Once Rajput makes someone a guest, then he does not have a sword on it.

Rajput does not compromise despite falling into his enemy's captivity.

Rajput rookie does not cheat with the enemy.

Asrutan does not hesitate to take off the bracelet and lift the sword to protect her style and religion.

Instead of falling into the hands of a godless person, the sarunaa considers it proper to take jawar and consume it.
