Which Ubuntu 20.0 command , I use most of the time?? Guess??

I don't know what Error I am facing in Ubuntu 20.0 LTS , but most of the time my TouchPad Stops. I tried many commands , many settings and updated apps many times , but nothing worked , unless I find one command.

sudo modprobe -r psmouse

and then ,

sudo modprobe psmouse

and touch pad starts again.

So I use this command a lot of time.

If you have any problem like this , please share and give the solution also.

Why I prefer Angular over React

Angular is a full framework whether React is a JavaScript centric library with speed in mind, but tends to be difficult for developers.

The Google-backed framework has risen to become the incumbent JavaScript framework of choice for building dynamic single page applications (SPAs) on the web.It uses various attributes and custom HTML elements to provide functionality on various Document Object Model (DOM) elements.

Angular can be used in many platforms :

Progressive Web Apps

Use modern web platform capabilities to deliver app-like experiences. High performance, offline, and zero-step installation.

Native

Build native mobile apps with strategies from Cordova, Ionic, or NativeScript.

Desktop

Create desktop-installed apps across Mac, Windows, and Linux using the same Angular methods you've learned for the web plus the ability to access native OS APIs.

Speed and Performance

Code Generation

Angular turns your templates into code that's highly optimized for today's JavaScript virtual machines, giving you all the benefits of hand-written code with the productivity of a framework.

Universal

Serve the first view of your application on Node.js®, .NET, PHP, and other servers for near-instant rendering in just HTML and CSS. Also paves the way for sites that optimize for SEO.

Code Splitting

Angular apps load quickly with the new Component Router, which delivers automatic code-splitting so users only load code required to render the view they request.

Productivity

Templates

Quickly create UI views with simple and powerful template syntax.

Angular CLI

Command line tools: start building fast, add components and tests, then instantly deploy.

IDEs

Get intelligent code completion, instant errors, and other feedback in popular editors and IDEs.

Testing

With Karma for unit tests, you can know if you've broken things every time you save. And Protractor makes your scenario tests run faster and in a stable manner.

Animation

Create high-performance, complex choreographies and animation timelines with very little code through Angular's intuitive API.

Accessibility

Create accessible applications with ARIA-enabled components, developer guides, and built-in a11y test infrastructure.

Why is Python simplest language and very good for competitive programming

I have done code in many languages but python is simplest :

In java the syntax in very lengthy. T write a small program in java you have to write a lot of code and it is very complicated also.

In c it becomes more difficult to write large programs because in c there are very few built in libraries.

Example : to use string in program you have to declare many thin like pointers and array.

But Python is slow :

Yes , python is slower than C and Java But it does not affect much until you are highly professional coder and until you have to think a lot about speed.

In Competitive programming

now a days i am using python because i can write code fast as well as it is very simple.

So , Good Luck , and use language with is most suitable for you

Connect computing with biology

Source : Moleculargenetics.it

Bio computers use systems of biologically derived molecules—such as DNA and proteins—to perform computational calculations involving storing, retrieving, and processing data.

The development of biocomputers has been made possible by the expanding new science of nanobiotechnology. The term nanobiotechnology can be defined in multiple ways; in a more general sense, nanobiotechnology can be defined as any type of technology that uses both nano-scale materials (i.e. materials having characteristic dimensions of 1-100 nanometers) and biologically based materials.^[1] A more restrictive definition views nanobiotechnology more specifically as the design and engineering of proteins that can then be assembled into larger, functional structures^[2]^[3] The implementation of nanobiotechnology, as defined in this narrower sense, provides scientists with the ability to engineer biomolecular systems specifically so that they interact in a fashion that can ultimately result in the computational functionality of a computer.

My 3 favourite Books..you should read these books.

1. _Rich Dad Poor Dad Book by Robert Kiyosaki and Sharon Lechter

Rich Dad Poor Dad is a 1997 book written by Robert Kiyosaki and Sharon Lechter.

Robert Kiyosaki followed the book with Rich Dad's Cashflow Quadrant and Rich Dad's Guide to Investing. He has at least a dozen books published.

2 : The Subtle Art of Not Giving a F*ck Book by Mark Manson

The Subtle Art of Not Giving a Fuck: A Counterintuitive Approach to Living a Good Life is the second book by blogger and author Mark Manson.^[1] In it Manson argues that life's struggles give it meaning, and that the mindless positivity of typical self-help books is neither practical nor helpful. It was a bestseller.

3. The Secret Letters of the Monk Who Sold His Ferrari Book by Robinsharma

The Monk Who Sold His Ferrari is a self-help book by Robin Sharma, a writer and motivational speaker. The book is a business fable derived from Sharma's personal experiences after leaving his career as a litigation lawyer at the age of 25.
