SpaceX’s Starship SN15 lands successfully

Key points:

•   Elon Musk's SpaceX sends off and then landed the newest model of its Starship rocket on Wednesday.

•  The flight was the fifth high-altitude test of a Starship model and the first that came to an end without the rocket crashed.

• Musk's company is growing Starship to originate cargo and people on missions to the moon and Mars.

On this Wednesday, Elon Musk's SpaceX launched successfully and landed the latest model of its Starship rocket. It settled in one piece, and as the official live stream came to an end. Tiny methane fire can be still found at the base, but so far, it has remained intact.

Elon Musk tweeted "Starship landing nominal" as he plans for his presentation on Saturday Night Live, and a stream from columnists in the area reveals that SN15 will remain to stand on the pad. At the beginning of this month, $3 billion has been awarded to SpaceX by NASA to establish a lunar variation of Starship to transport astronauts to the moon for the sake of the agency's Artemios missions.

Earlier this month, NASA awarded SpaceX a nearly $3 billion contract to build a lunar variation of Starship to carry astronauts to the moon's surface for the agency's Artemis missions. Though, while Musk's company persists in moving forward with Starship evolution, NASA put on hold SpaceX work on the HLS program after Jeff Bezos' Blue Origin and Leidos' subsidiary Dynetics each registered objections to the NASA settlement grant.

The Starship SN15 flight was quite similar to the ones SpaceX has conveyed in the prior six months, with the inspection flights of models SN8, SN9, SN10 and SN11. While all of the previous rockets launched firmly and completed various expansion goals, all four prototypes were explosively demolished– SN8 and SN9 on collision during landing trials, SN10 a few minutes after landing, and SN11 minutes before its landing trial.

The SN11 transportation didn't get it back to the ground, while SN10 settled briefly before collapsing after landing too severely and damaging its legs. With one solid high-altitude test below its area, SpaceX has gone closer to its conception of reusable Starships that fly to the ISS, the moon, around the Earth and beyond.

The Starship models stand at about 150 feet tall, or about the size of a 15-story building, and three Raptor rocket engines power all. It is composed of stainless steel. It resembles the last variant of the rocket that Musk revealed in 2019. SpaceX recorded in a report on its website that SN15 features "vehicle improvements across structures, avionics and software" associated with the previous Starship models.

"Specifically, a new enhanced avionics suite, updated propellant architecture in the aft skirt, and a new Raptor engine design and configuration," announced. The Federal Aviation Administration, which has an investigator at SpaceX's facilities to observe the test flights, conducted a "mishap" investigation of the SN11 flight.

Last week the FAA announced the authorisation of the following three Starship launches – Starship SN15, SN16, and SN16 – saying it will "verify that SpaceX implemented corrective actions arising from the SN11 mishap investigation." The FAA authorised multiple launches at once "because SpaceX is making few modifications to the launch vehicle and relied on the FAA's approved methodology to calculate the risk to the public."

However, Elon Musk has promised a lunar excursion in 2023 to the Japanese online retail billionaire Yusaku Maezawa. Mr Maezawa will fly around the moon in a Starship with eight other members. Musk has also stated that he will initiate transporting on uncrewed aviation to Mars in 2024. Even if the  founder's timelines might appear positive at times, he has also acquired a status for ultimately reaching his ends, no matter how formidable.

New iMac with Advanced M1 Chip and 4.5K Retina Display

The first time Apple has revealed a new iMac gamut of striking and appealing colors, presenting a more compressed and slim design enabled by the M1 chip. It gives a robust performance in a significantly less and thin display of just 11.5 millimeters, through 500 nits of sharpness, 24 inches 4.5 retina display along with 11.3 million pixels, and beyond zillion of colors that provides rich screening experience.

New iMac Features:

It also comprises a 1080p HD camera, quality mics, and a six-speaker audio system, making it the supreme audio and camera in Mac ever. Hence, Touch ID gets in the device never before, making it easier to log in safely, buy things with Apple Pay, and switch user profiles by finger touch. 

Apps are launched with astonishing speed by blending the potency and functioning of macOS Big Sur and M1. The regular task gets much quicker and smoother, like editing a 4k video, and the large picture gets done quickly as ever.

iMac is the most intimate, mighty, competent, and amusing it has ever been, and buyers can place an order for it at the beginning of Friday, April 30. iMac will be available from the second half of May.

Fresh Designs Enabled in M1

The brand new iMac is remarkable from each angle due to its thinner and compressed design. It is enabled by the brutal power efficiency of M1 and system-on-chip architecture. The thermals and logic board are combined and condensed in size compared to the earlier generations, which leads to the lost view of the side profile of iMac. The significantly more compressed figure of the Mac lessens the volume of iMac by fifty percent, occupies less space, and is handy in any place.

The new device comes with soft colors and slim front borders that permit users to concentrate on their content. It comes in a range of colors like pink, blue, purple, yellow, silver, and orange that can be easily customized and fits in less space than other laptops or desktops.

The new iMac presents a 1080p Hd camera that is the best in Mac, giving the best video quality and best performance in dim light. It takes the benefit of picture signal processors in the Neural engine and M1 chip, which enhance the quality of the image by improving noise cancellation, more excellent powerful range, and better image quality by automatically adjusting the exposure according to surrounding lighting. Hence, the user will appear best while connecting with relatives on a video call.

The new Mac is accompanied by studio-quality studio-quality three-microphone for uninterrupted calls and crystal-clear audio recording, which makes it distinct from others. 

 

It comprises woofers of force-canceling on both sides for effective results by lowering random vibrations, making it a great sound system. The pair is stabilized with the top-performance treble speaker. Hence the product is an enormous sound stage with powerful bass clear-cut mids and high.

Low Environmental Impact

The new Mac reduces its influence on nature because it is formulated by utilizing a less-carbon aluminum compound and entirely reusing the tin combining with the critical logic board. Therefore, Macs will always be liberated from dangerous compounds and meet Apple’s special status for power efficiency.

Does Google Measure Up work up to our Expectations?

Be it your house or your office. Wall-fittings to furniture have to be set up perfectly, and for that, you need to measure up so that everything is in its place.

The traditional way of measuring up is using inch tapes or scales.

Google has introduced an app,' Measure,' which aids you with measuring processes much more efficiently than the tape measure.

With the Measure app's aid, you can determine the length and breadth of tables, sofa, etc., and read the output in the way you choose, which could be metric or imperial units.

How to set up Google Measure Up? 

The step by step procedure of setting up the app on your Android phone / Tablet is

• Locate the Google Earth app.

• Choose a location or search a place on the Globe.

• Now ' Tap' Measure.

• Now various ' Measurement Points ' appear.

• Now, you can move the map and locate the ' Add point, 'which you can tap.

• In case you need to remove an additional point, just press ' undo.'

• If all measurements are over and added up, go to the top portion of the screen and tap ' Done

• Check below for distance measurement.

The Accuracy:

Measure can sustain accuracy can be sustained up to 2000 feet distance. These include the on and off roads and also the curved path.

Found below are the five measuring apps that are considered best in Android.

GPS field Area:

Considered the best, it utilizes existing technology in the best way possible.

By using GPS data, the app can measure a particular distance or even an area. To do this, first, choose the starting and ending points and click on' Measure.'

Ruler:

A simple but realistically app, the Android phone itself becomes a Ruler. The intelligent ruler has everything in it that an ordinary ruler has. Unit conversion is possible through this Google app.

Image meter- Photo Measure.

Photometer differs from the GPS Fields in only one way. It does not warrant the use of the camera and instead runs the image on an existing image.

Smart Measure:

The camera is used extensively in this app as it lets you measure up the distance and height with great accuracy.

Easy Measure:

Apart from measuring the object's distance, which lies away from the user, this app can perform an additional function. It can also measure its dimensions. The app has a simple procedure to be followed. Aim the camera at the object.

The solutions or calculations vary with the tilt of your camera. Therefore, it’s best to achieve the perfect positioning of the Android phone.

Other Android apps to Measure a few more things are

• Decibels

• Displacement

• BP

• Temperature

Conclusion:

It is the smartphone that determines the measure app's efficiency. Therefore, if it lows in performance, the app's accuracy would also be far from accuracy.

In case you are using the best smartphone, the accuracy of the application would be good but not 100 percent accurate. The information you receive would be enough to make decisions is the bottom line.

FLUTTER 2- A Leap into the Future

The major announcement of the Flutter 2 launch was made on March 3rd, 2021, by the Google Developers. It was significant in the sense that the upgrades were many over the previous version.

It enabled the developers to work almost on any platform and, in the process, create and build apps that are more fast, portable, and beautiful. The advantage was that it was a common codebase, and apps can be shifted without any issues and made workable on the top five operating systems.

The operating systems were:

• Windows

• Android

• IOS

• Linux

• MacOS.

You can use it to target top browsers such as Edge, Chrome, Firefox, and Safari. As far as portability was concerned, it could easily be embedded in Television, Cars, Smart Home Appliances, thus making its presence felt and an experience in the world of computers.  

It was to introduce a new mindset, especially the Developers' perspective. The 360-degree change Flutter 2 brings around is the experience that has to be created and not the platform itself. In this process, the design is found at the forefront, and branding also occupies an important position.

The advantages of Flutter 2 

• It is the fastest in compiling the source code to machine codes.

• And It enables you to make changes with the application still running.

• It permits you to see the results of such changes in real-time.

• It is open-ended, thus allowing for many contributors who can enhance the core framework.

• Flutter is not confined to a mobile framework but also available on a portable one. This helps your apps to run on various platforms with no changes.

• There are PWA's which Integrate well with the user (like Twitter), and their quality stands enhanced. These enhancements include offline support, installation, and the tailored UX.

• The web support provided by Flutter to complex standalone apps makes it easy to reach various users on an unrestricted number of devices.

Flutter & the Web:

There is no difference in his Flutter performance on the web compared to the mobile. With the additional flexibility of Flutter and its combination with the web platform's power-building new applications for Android and iOS, the browser is also of the same codebase.

It brings with it many new and exciting additions. They are :

• Web:

It has helped to leverage web platforms' strength and has thus created a base for interactions between web applications.

• Sound Null Safety:

It is essential to distinguish between nullable and non - nullable types. Dart language has an add-on through Sound Null Safety. Apps generally crash as there are null errors, but with Sound Null Safety, this is preventable.

Pros and Cons:

Pros:

• Code writing is faster

• Testing is lesser

• Apps work faster

• Similar code / single code for two platforms

• User lovable designs.

Cons:

• Non- availability of certain functionalities

• As on date, Flutter is not supported by a few CI platforms.

Conclusion:

The advantages of Flutter 2 outweigh the disadvantages. It presents an excellent opportunity for high performance and is capable of satisfying your custom requirements.

Is The Google FI VPN The Best?

Google has come out with their own ' VPN' (Virtual Private Network) on all Fi phones to eliminate this. Let us discuss is the Google FI VPN is best or not?

Our dependency on the mobile phone has exceeded all limits, and we are highly dependent on them for many important things. In this process, we are unaware of what repercussions are expected to happen as we pass on vital information.

They may include credit card numbers, passwords, etc., which hackers can conveniently pick up in transit and use for their gains.

What is Google Fi VPN?

Using Google Fi VPN, there are no changes that would affect the process of browsing, streaming, and downloading, with the connection being encrypted and private. In other words, you are given a free run despite the fact you are using insecure networks.

The most significant advantage is that none can locate your IP address, and hackers will have no clue that you even exist.

Found below are improvement made to this process of Google Fi VPN after its introduction:

• It enables double-layer protection against your Phone number. 
• Provides complete privacy and more security. 
• Personal information is completely protected. 
• Performance improvement but may slow down the existing speed. 

The new Fi VPN does promise this, but are there doubts regarding these claims?

1. Anonymity and protection:

The argument of using the Google Fi VPN is to:

• Protect ourselves from hackers 
• Preventing ISP's from collecting all our data and selling to organizations who will benefit from them. 

This is a valid argument provided you want anonymity from your ISP and is justified. But one should never forget that you cannot stay hidden from Google itself.

They would track every movement of yours and bomb you with advertisements in all the products or sites you show interest in!

2. User identifiers and Google's claim:

Google states that any data browsed cannot be traced back to the user. Such a disclaimer does cast doubts because:

• All your activity is passing through Google. 
• Google knows where the activity has been initiated 
• There is no assurance from them that they would not use the information to their advantage 
• They have the ' know-how' on how to collect your data. 
• The question then is how much you trust Google. 

3. Speed and performance compromised:

Various VPNs state they aim to provide complete security but not sacrifice the speed or performance you have experienced before. Google, on the other hand, through their Fi VPN, says:

• All the data will flow through their one channel 
• There would be increased mobile data which is not less than 10 % 
• Due to this, the users would' experience slight slowdowns.' 
  

This is actually in direct contrast to the statement made by other VPNs!

4. Ability to Bypass:

Fi VPN from Google is expected to do wonders on its ability to bypass all restrictions. However, it remains non-committal on bypassing geo-restrictions and blockade from many countries.

The fact is that the Fi VPN cannot change the country of origin, thus allowing the region to block you. The traditional VPN does not suffer from this issue.
