SpaceX Launches First Internet Satellites In Space, Here Are 9 Facts You Need To Know

SpaceX has successfully launched Falcon 9 rocket carrying demo satellites for its broadband network. Here are some interesting and important facts about the launch.

1. A SpaceX Falcon 9 rocket deployed two demonstration satellites, named Tintin A and Tintin B. These satellites are a part of SpaceX’s much-discussed broadband service from space.

2. The internet network, named Starlink, will consist of thousands of operational satellites once the testing is completed and the network is up and running.

3. SpaceX Falcon 9 launcher was 229 foot tall, i.e., 70-meter.

4. The launch took place from California’s Vandenberg Air Force Base. The two-stage Falcon 9 also had the Spanish PAZ radar observation satellite as its main payload.

5. After the launch, Elon Musk tweeted that satellites will attempt to beam “Hello World” when they pass near LA.

6. SpaceX executives hope that Starlink will start operating by 2020, at least in a limited capacity. These first test satellites will collect information useful for testing.

7. Just last week, FCC Chairman Ajit Pai announced that he had endorsed Starlink. FCC has also approved similar requests from other companies like OneWeb, Telesat, and Space Norway.

8. This launch also included SpaceX’s first attempt to catch Falcons falling payload fairing out of the sky. The company attempted this catch using a boat named Mr. Steven.

9. As per Musk, the boat was a few hundred meters away from the $6 million fairing. However, the fairing arrived in good shape.

Google starts rolling out ‘Call Screen’ feature for Pixel smartphones

San Francisco, Dec 2 (IANS) Google has started rolling out a feature for its Pixel smartphones that lets users make use of the Google Assistant to see who is calling and why before they answer a call. The feature allows users to see a real-time transcript of how the caller responds so that they can then decide whether to pick up, respond by tapping a quick reply (for example, “I’ll call you back later”), or mark the call as spam and dismiss. “Call Screen is only available to English speakers in the United States who have Pixel 2, 2 XL, 3, or 3XL devices. If you don’t see Call Screen in the Phone app’s settings, it’s not available yet,” Google said. Call Screen, which can help users save the time spent on picking up unimportant calls from unknown numbers, does not use Wi-Fi or mobile data of the user. This feature does not work with third-party call recording and screen recording apps as these apps may interfere with how the feature works. It is better to turn off these app...

Chrome Web Browser Will Now Use 10% More RAM With Spectre Fix

A new security feature named ‘Site Isolation’ has been introduced for Google Chrome 67 which would nullify the effects of speculative execution side-channel attacks like Spectre. To put things to the perspective, Spectre is one of the two fundamental design flaws in the modern processors, which allow programs to get access to the data for which it is not authorized. Malicious data can exploit this flaw to steal your password and other personal information. What is Site Isolation? The new Site Isolation feature introduced in Google Chrome 67 brings about a fundamental change to Chrome’s architecture. Now, Chrome has changed how its multi-process architecture worked and different tabs used different render processes. According to the new architecture, Chrome limits each renderer process to a single site. By this separation of processes, Google aims to prevent direct memory reading across different processes to safeguard users’ data. According to G...

Amazon, Reddit And Others Fail To Warn Us About Dumb Passwords

B elieve it or not, there is still a large number of people who use passwords such as “password,” “password123”, “[dog’s name]1” and others along the same lines. And in the era of sophisticated hacking, these passwords are not exactly “safe.” Before me, this is the first thing websites should inform you while setting up a password. But apparently, many big names are not doing enough to encourage non-terrible passwords, according to the new research . Steve Furnell from the University of Plymouth has been keeping tabs on the websites like Amazon, Reddit, and Wikipedia for many years, carrying out similar assessments in 2007, 2011 and 2014. His 2018 survey examined practices of Google, Facebook, Wikipedia, Reddit, Yahoo, Amazon, Twitter, Instagram, Microsoft Live, and Netflix. The study concluded that Amazon had the worst performance among all the names. It nearly accepted every kind of password of any length. On the other hand, Yahoo and Wikip...
