---
As the new decade is here, We have a new set of smartphones which came into the market. The Korean Company designed their first 2020 smartphone series and is now available to the consumers.
As always, there were a lot of speculations on the design perspective of this gigantic smartphone. The flagship S20 series comes in 3 different variants, the Galaxy S20, the Galaxy S20 Plus and the magnanimous Galaxy S20 Ultra.
All 3 smartphones are have the famous water drop pin-hole front facing camera and the special focuz on these phones, especially the S20 Ultra is the 100 Megapixel space Zoom. The S20 Plus has a mediocre 30 Megapixel zoom with enhanced picture quality.
These phones also come in different sizes, the S20 comes in a handful 6.2" Dynamic AMOLED 2X whereas the S20 plus comes in a 6.7" Dynamic AMOLED 2X and the S20 Ultra, as the name suggests, comes in a gigantic 6.9" Dynamic AMOLED 2X.
Samsung also managed to increase the battery capacity of the smartphones, the S20 and the S20 Plus have a manageable 4000 and 4500 mAh whereas the S20 Ultra has a magnanimous 5000mAh battery Capacity.
#Welcome to 5G
--
Huawei being the 1st Smart Phone producer to incorporate the 5G technology into their Mate30 Pro 5G smartphone, Samsung is also one of the first producers to incorporate 5G Compatible technology into all of their flasgship smartphones.
#Software Specs
--
Apart from te hardware aspect, the software has also been upgraded from OneUI to the OneUI V2.1. A couple of years back, we got the first lightweight and smooth UI created by Samsung and purging the old TouchWIz UI. With the new flagship line, we also have a lot of new changes made to primary version of OneUI. It has become a lot easier and faster with almost no noticeable lags, the korean company did a fabulous job in terms of the software aspect as well.
All the phones are now packed with 64-bit octa-core processor (Max 2.7GHz + 2.5 GHz + 2.0 GHz).All the phones are Android 10 pre-installed.
#Color Specs
--
The Galaxy S20 comes in three colors: Cosmic gray, Cloud blue and Cloud pink.Like the standard Galaxy S20, the S20 Plus comes in the Cosmic gray and Cloud blue colors. Instead of Cloud pink, though, the S20 Plus offers a Cosmic black option.
#The Camera Bump
--
Samsung's first quad camera smartphone was the Galaxy A9. The picture quality isn't that great but the innovaive quad cam idea was exceptional.The Galaxy S20 series also has a quad cam option , that is with the S20 Ultra.
The S20 ultra is packed with 108-megapixel (wide-angle), 48-megapixel (telephoto), 12-megapixel (ultrawide), time-of-flight camera.
The S20 Plus has a reasonable 12-megapixel (wide-angle), 64-megapixel (telephoto), 12-megapixel (ultrawide), time-of-flight camera and the S20 has a mediocre 12-megapixel (wide-angle), 64-megapixel (telephoto), 12-megapixel (ultrawide).
All the phones have exceptional yet storage eating 8k recording capabilities which can take clean, eye catching and pure videos.

My Coding History
--
Right now, I am a computer Science student who learnt a lot of languages and coded many programs. But all this started years back, when i first wrote my Hello World! program in Java in my school days. That's when it all started off. My First programming langiage was Java and believed that it was the best programming language that was out there and when i came to university, that perspective changed... for the the better.
As of now, i have learnt over 14 Programming languages which includes declarative,imperative and web Programming as well. Database management systems is also a key learning factor while learning programming languages.
Pre-Basics of coding
--
Well, before learning the basics of coding, we all need to understand in what to code and why with emphasis on the latter. There are thousands of programming languages out there and choosing to learn one language to begin with is a hard task. That comes to the second question of why.
Well,I believe that if you start learning a more Non-Abstracted code language like C and Java, it'll help you understand how recent and more professional code languages like Python work behind the scenes.
Keeping that in mind, i would like to give you some languages to start working on and learning the basics of the language.Remember, Learning WHY is more important than WHAT the code does.
- C (Best to start with)
- Java (Good option as well)
- C++
## What to start with?
--
Every language has it's own syntax and it's own concept, but the basics remain the same. You have to first understand these basic concepts:
1. [Classes and Objects](https://www.youtube.com/watch?v=MeP1CztNMdo&feature=emb_logo)
2. [Encapsulation and Inheritance](https://www.youtube.com/watch?v=QXHOrKEjHo0)
3. [Polymorphism](https://www.youtube.com/watch?v=AmdgVatPL9k)
These concepts make the building blocks of [Object Oriented Programming](https://www.youtube.com/watch?v=xoL6WvCARJY).Only after you are thorough with these topics, you should have your *hands on coding!!*.
![4 Pillars of OOP](/images/coding-post-1.png)
Now, These pillars of OOP as some call it, are essential and build your foundation for coding any language,well,technically.
## Resources that will teach you the ABC in programing:
- Google started it's own teaching platform called [DigitalGarage](https://learndigital.withgoogle.com/digitalgarage) which enables anyone with a google account to sign up and learn programming and many more courses online.
- [Coursera](https://www.coursera.org/) is another webiste which gives you detailed explanation and implementation from various top universities.
- Another website like coursera is [eDx](https://www.edx.org/), which is packed with various new and innovatiove material and gives you the pleasure of learning at your own pace.
- Saving the best for last,[OpenClassrooms]() is another website, which i personally love, gives detailed, step by step instructions and explanations with video reference to most of the languages out there and I personally prefer this website.
All the learning materials and quizes are free and these websites give free (and sometimes paid) certifications as well. This will help you immensely while creating your profile and makes you stand-out in the eyes of the employers.
## Other resources that might help you
Well, these resources are very helpful in any point ,while learning or implementing your code. Most of the time, professional coders also refer to sites like these when they lose their path.
- [stackoverflow](https://stackoverflow.com/) --> This is like "Quora" for coders.
- [GeeksforGeeks](https://www.geeksforgeeks.org/) --> This shows the implementation and explanation of various methods in libraries.
& so much more!
Even after you have done a professional course in anylanguage, you may lose your way and would have to refer these websites, so never discard them.
## Where is the world heading?
In my opinion, we are heading to the ineveitable destination, Machine Learning, Artificial Intelligence by utilising skills like Data Analysis and Data Science. My goal is to learn new concepts in programming and applying it in Machine learning and the like.

## What are Flight sims ?
A flight simulator is a device that artificially re-creates aircraft flight and the environment in which it flies, for pilot training, design, or other purposes. It has been really popular since 1982. The first release was called subLogic flight simulator which was released in 1979 on the Apple II.
![](https://i.ytimg.com/vi/vK-iIrIEOyc/hqdefault.jpg)
Since this release flight sim has completely evolved with newer versions with newer features which means more and more accurate modelling of newer aircrafts.
### Important milestones:
- Flight Simulator 2.0:
![](https://s.uvlist.net/l/y2014/01/122928.jpg)
- Flight Simulator 5.1:
![](https://i.ytimg.com/vi/dHpzHYHcqV8/hqdefault.jpg)
- Flight Simulator X:
![](https://s3-eu-west-2.amazonaws.com/assets.fsxinsider.com/app/uploads/2015/09/27215612/Image2.jpg)
Flight sims have also become part open source. The current best flight simulator in the market Xplane 11 has open source modules such as BetterPushBack , SharedCockpit etc ... In recent years flight school students can even skip most of the instrumental classes for aircrafts such as the Ceesna's due to the fact that they have already learned it in the flight sim at home.
## FS2020 Competitor
Before we start the discussion of FS2020 we need to compare the current progress of their competitor [Xplane](https://www.x-plane.com/) which is designed by a Software Company called [Laminar research](http://www.laminarresearch.com/). Xplane 11 is the current best Flight sim platform out there. Xplane 11 comes built in with VR compatibility , Runs on all platforms such as Mac , Windows , Linux and the graphics speaks for itself and runs on most common Pc's on today's standards.
![](https://steamcdn-a.akamaihd.net/steam/apps/269950/ss_35a2520bad426346196ac6e2aa96883e96f84e59.1920x1080.jpg?t=1586961059)
[XPlane 11 in VR](https://www.youtube.com/watch?v=31S_jUy3h7Q&t=887s)
## Introduction to FS2020
The release date of FS2020 is still unknown due to COVID19 delays. All we know is that it should be coming out sometime this year. The idea is that the game is rendered on your PC but the scenery is downloaded from the azure servers. The reason it has a lot of hype is because of the fact that it's graphics is game changing and even the amount of realism that they have added to the game (We will talk more on this later).
## Ground Scenery
![](https://lh6.googleusercontent.com/sagSw47Tw5K8i9KLgN-SZVKudzYN4B2UJu78qEiKZniaTaEWmFRkj673Cr4CCkISZgvYk0Q5mk-HF-2SU_tUfn_PqzCoCBbjK8q1Ur1X9lzlQJQjvvJV_p59qdPV470iw3uOZTwM)
The game has an online and offline maps. The Hype comes from the online maps as it's a 3D map from Bing. With the current technology, satellites are able to take a picture of cities from different angles and generate 3D models out of them and the game developers have been using a lot of machine learning techniques to generate the tiniest details such as grass ,trees , cars on the road etc.. There have also been very funny comments on these 3D maps such as "Tips on how to tour north korea", "How to catch your wife cheating","This video gave me morning wood. Girlfriend thought it was because of her. Yea honey....it's totally you." etc...
[This link will give you a general idea on 3D models of cities look like](https://earth.google.com/web/@40.71247137,-74.0072421,27.70327415a,2644.644745d,35y,35.47111927h,60.00244366t,0r)
For higher details many of the major airports are modeled partially manually. The movement ground crew and vehicles are all a bunch of AI's working in parallel. The details of the runway and taxiway are super high. In the demo we can even see tiny stones on the taxiway.
As per the developers the 3D models are generated using Photogrammetry data or else it's augmented bitmap which means that the base image is from bing maps and then it's filled with some pre-build objects. The size of the bing scenery which they use is around 2 Petabytes and this is only one aspect of the Sim. All the maps are generated or drawn based on the horizon and this varies based on the height of the aircraft.
## Behavior in the Sky
![](https://lh5.googleusercontent.com/_vxFWb0lLyo-NnwgypPoz4m0EFRbNX4qh54E5-YvnlPZ1cZEo-xW7kv9MqK06ns561bTfS2_QTwi13uEnU1CcLDBo8G9mg84nGBhvBqPiXl0fBU2K124CfedGS7_IOlpxG2PkjxD)
Again for the weather there is online and offline data. Is it actually interesting to know that simulating or modeling the weather is as complex as doing it for the ground. To simulate that the game generates millions of virtual particles to generate accurate lift for the aircraft. In many other sims the stalls in the code have been like flags (i.e on and off switch) this means that when the aircraft loses speed the nose dive will be a bit unrealistic. This has been fixed in FS2020 and they calculate various aspects such as density of air , wind patterns because at many times the aircraft would not even stall due to the design of the hardware which automatically pushes the nose down to gain speed. FS2020 can even predict which direction the aircraft will stall at.
### Atmospheric Simulation:
The developers had to use a fresh approach to ensure that the lighting effects have to be as realistic as possible and to also accommodate all new techniques coming out from the video game industry. They have their own scattering system which gets lights from unified sources such as Sunlight ,Moonlight ,Starlight ,City light etc... The photons are scattered based on the parameters such as humidity , weather , pollution etc ... The shadows of the clouds are casted on the ground , shadows of the ground have been casted on the clouds and so this gives unbelievable sights.
### Weather Special Effects:
The sim has volumetric 3D rain , volumetric Rainbow scattering; this means that the rainbow is generated based on the compositions required to generate one. Each water droplet on the windshield is generated based on the speed of the aircraft and as the aircraft speed varies this impacts on how much the water is stretched in the windshield of the cockpit.
The sim even has window icing that takes place mostly in the cruise altitude if the Anti ice systems are not turned on in the aircraft.
The position of the sun , moon and stars will be informed based on date and time of year and even the light of the city will be reflected back to the cloud which creates realistic VFR flying. The reflection of the building on water is also realistic based on time of day, number of clouds etc.. and it is rendered the same way as how the atmosphere is rendered.
### Volumetric clouds:
This is one of the best features for anyone flying aircraft's through clouds. There are 32 layers from sea level and they are based on density , shape , fuzziness and all these clouds can be seen from any angle. The formations are informed based on the updraft winds. The sim natively supports all types of clouds. The max view distance of generated clouds is 600 km.
### Real Weather Data:
The weather data is collected from one of the research centers in Switzerland. Based on data provided to the engine, The corresponding clouds and updrafts are generated. The sim gets upto 32 layers of real world cloud data, pressure , humidity, temperature, wind speed and gusts.
## Specs for the game:

title: The all new 3-cam iPhone
date: 2020-03-24
hero: /images/iPhone-11-post.jpg
excerpt: All new updates on this magnanimous smartphone.
timeToRead: 5
authors:

The title is not entirely accurate, obviously because there is the iPhone 11 which has only 2 cam's and missing the telephoto lens. Well, the cheaper variant is assumed to have limited features, but the American tech supergiant has not compromised on any major hardware or software aspect of this phone which is commendable.The iPhone 11 comes in 3 different variants, the iPhone 11,iPhone 11 Pro and the iPhone 11 Pro Max.
The major change made to this phone and it's predecessor is the new camera lens. Like many other competetors, Apple also designed their first 3-cam smartphone.
The iPhone 11 has the wide and ultra wide angle cams and not the telephoto lens. It also comes with the iconic Night Mode which is automatically switched to when low light is detected.
The iPhones come in multiple color variants, theres a new midnight green color, refreshed silver,refreshed space gray and a new gold finish.
#Triple Cam
--
Apple has added the Ultra ide angle cam lens instead of a new telephoto lens which many of us expected. The Ultra wide lens is @ 0.5X zoom and it can go upto 2X zoom. The ultra wide angle lens also has an f/2.4 aperture and a 120-degree field of view.
Similar to the Google Pixel, Apple have also come up with a new night mode to take low-light mode shots.
The teh giant stepped a bit further by creating the "Deep Fusion" tech. This is a technology combines photo data from the 3 lens and fuses it to get a Deep and clear picture of every shot which is said by Senior Vice President of Worldwide Marketing Phil Schiller, "computational photography mad science."
The Front camera has also gone through some upgrades, it has been upgraded to the 12-megapixel zoom sensor and can accomodate a lot more people with every front cam shot.
#My Personal View
--
With all this being said, We'll get down to my say. Frankly, i did not see a major upgrade in most of the aspects except a few and I don't see as to why there is a new phone upcoming into the market with not a lot of upgrades.Apple phones have now reached the ultimatum in terms of the price and quality and perhaps innovation as well. Well, like i said , there has been some developments and from various sources, We can say that the photo department did a good job in generating absoulutely amazing shots from every click.
The last iPhone to have a fingerprint sensor was the iPhone 8 and after updating the design to an almost infinity display touch screen, Apple removed Touch iD . With the latest Optical Fingerprint tech, they can incorporate touch iD from under the screen. This is one of the many things Apple could really work on to get on the top of the arguably "Best Phone in the Market".

#What is OnePlus?
--
We all have seen that in recent years, mobile tech has increasingly improved in many aspects.
We have all witnessed the creativity to make technological wonders. Slowly and gradually, the inevitable has happenned, rise in technological competetion forcing the existing brands to improve their R&D to compete.
Amongst all the brands, one well-renowned, Shanghai based company grew exponentionally, that is the OnePlus Corporation. This tech giant flew right in the hotspot tech companies competing Apple, Samsung, Huawei and other major companies in the league for the gold-winner in the arguable "Best Phone in the Market".
The consumer world started getting a glimpse of their technological marvel after the OnePlus 3. Mainly because of its prodigal specs at a very resonable price.
#The 7T and 7T Pro
--
If you want me to describe this phone, I need 2 words, 'Smooth' and 'Fast' and ofcourse "Never Settle" as the company tagline goes by.
These phones came into the market in the late 2019 making the culmination of the year a fruitful one, disregarding the iPhone 11 (that is!)
It is a manageable 6.3" smartphone with a dual side gorilla glass 5 protection with an aluminium frame.
#OxygenOS
--
It comes out-of-the-box with an Android 10 and an OxygenOS 10.0.7, which is an android based OnePlus Developed Tech. Hands down, the lightest and (arguably) the smoothest OS of all. Unlike android which is written in Java, OxygenOS is written in C++.
#Camera Specs
--
This beautiful piece of tech has 3 Cameras, A 48 MP wide cam, 12 MP telephoto cam and a sufficient 16MP ultrawide cam with autofocus capabilities.Videos can be recorded in 3 different resolutions at different speeds, the 2160p @ 30/60fps, the 1080p @ 30/60/240fps, 720p @ 60fps
When we come to the selfie camera, comes packed with an Auto HDR 16 MP f/2.0 camera and records videos @ 1080P @ 30FPS resolution which is great for a smartphone of this time and age.
#Hardware & Software
--
This phone comes in a Snapdragon 855+ chipset with 8 cores of CPU. It has 2 storage variants, the 128GB and 256GB and 8 GB of RAM.It also has a really smooth and secure Optical fingerprint, right under the screen which works under dust and watery fingers.
#Charging
--
Comes packed with a Big 3800 mAh battery with 30W fast charging capabilities and with a Warp Charging 30T charger out-of-the-box.
#My Personal View
--
Well, let's come down to my personal view at this Smartphone which bested at almost all the aspects of a smartphone.
This phone has all the features that I would like to see in a smartphone for a long-run. But obviously, the removal of the classic 3.5 mm AUX port has had a lasting effect on my wired earphones😂. Oh yes, as well as the removal of the expandable storage facility is also not expected and I am sure they will find a new way to get more storage into piece of tech.
The Shenzhen based firm did a pretty impressive job developing such an awe-inspiring piece of tech. I would like to give it a 9/10!!
So, that's that for now, tune into my blog for more reviews to the latest and innovative Pieces of Tech.
