What is Progressive Web Apps? 

Progressive Web Apps (PWA) was announced by Google in 2015. This format of creating mobile websites attracted attention due to the relative ease of development and almost instantaneous interaction with the user. As early as May 2016, at the Google I / O Developer Conference, The Washington Post demonstrated its mobile hybrid site-application.

What is PWA? You can perceive this as a site built using web technologies, but which interacts with the user as an application. The advances in the development of browsers, cache and Push-interfaces allowed installing the application on the home screen directly from the browser, receiving pop-up notifications and even working offline.

Main differences between PWA and native apps.

1. In browsers of Google, Opera, Firefox and Microsoft PWA can be loaded on any gadgets, regardless of the screen size and other specifications. In addition, developers of browser data will offer users to install PWA on the second visit of the site.

2. Application developers note that creating a progressive application is easier and faster than a regular site.

3. You do not need an API with backward compatibility support. In the case of PWA, users run the same version of the site code (unlike classic applications).

And this is only the beginning. Microsoft is already working on the task of how to add progressive web applications to the Windows Store. Google in May 2016 voiced a long list of ideas for the development of advanced applications. And the fact that search engines will pay special attention to PWA in the future seems inevitable.

Google decided to close the social network Google+ not in August 2019, but in April. The reason was another vulnerability in the API, due to which it was possible to obtain private information of 52.5 million accounts. The company plans to close the social network API until mid-March 2019.

By December 10, 2018, the following error information was published:

  • Third-party applications requesting access to profile data, because of the bug in the API, received permission to view information, even if it is hidden by privacy settings;
  • the names of users, their email addresses, information about occupation, age and other confidential information were at risk;
  • passwords, financial data and national identification numbers have not been compromised;
  • the company has no evidence that anyone has exploited the vulnerability;
  • the error was fixed within 6 days: from November 7 to November 13, 2018.
  • Google said it sends notifications to all users affected by the bug.

The previous data leak of Google+ users occurred in October 2018. Then about 500 thousand accounts were compromised. The attackers could get the names, email addresses, age, gender and occupation of users.
