6 It has become appallingly obvious that our technology has exceeded our humanity.

7 “It is only when they go wrong that machines remind you how powerful they are.”

8 The Web as I envisaged it, we have not seen it yet. The future is still so much bigger than the past.

9 If it keeps up, man will atrophy all his limbs but the push-button finger.”

10 If future generations are to remember us more with gratitude than sorrow, we must achieve more than just the miracles of technology. We must also leave them a glimpse of the world as it was created, not just as it looked when we got through with it.”Lyndon B. Johnson, Former President of the United States of America

11 “Once a new technology rolls over you, if you're not part of the steamroller, you're part of the road.”

17 Measuring progress by lines of code is like measuring aircraft building progress by wieght.

18 The most important aspect of software development is to be clear about what you are trying to build.

WHAT IS VIRTUAL REALITY?

Digvijay Karadia — Fri, 19 Nov 2021 09:25:21 +0000

Virtual Reality (VR) is a computer-generated environment with scenes and objects that appear to be real, making the user feel they are doused in their surroundings. This context is formed inside a machine known as a Virtual Reality headset. VR allows us to involve ourselves in video games or movies as if we were one of the characters. We feel like we are doing the job and are realistic af. We can play any sport we like, we can perform surgeries, make food and do much other stuff to maximize performance.
Although this may seem remarkably ahead of its time, its roots are not as recent as we may feel. The very first virtual reality device was considered to be Sensorama. It was a machine that had built-in seat and it played 3D movies, gave of smells, and generated vibrations to make the experience as vivid as possible. This device was brought into existence back as far as the mid-1950s. Following technological and software advancements over the coming years brought with them a continuous evolution both in projects and in interface design.

That's enough about the theory that is propelling us into the future. Which sectors is Virtual Reality actually being used in today? Medicine, culture, education, and architecture are some of the areas that have already taken hold of this technology.

In near future, Imagine going into virtual reality when deciding what furniture to buy for your residence. You will be able to walk around in a virtual living room, bedroom, kitchen, etc, and know what kind of furniture would fit in your house. In those simulations, you will be able to try out different items of furniture. So virtual reality would make many things possible.

DEV handy tools for newbie

Coding, hosting - Glitch

After it was launched in 2017, Glitch has let everyone write and change codes and then issue bots, network apps, and other outlines that it would host for free. But with its pro's there were cons. That free hosting came with certain very strict limitations. Apps had restricted RAM and storage, and more importantly, they would be shut down if they went inoperative for even a few minutes, meaning you often had to wait through a torpid boot before operating them.

Command Line - Hyper
Hyper is a terminal focused on network technologies, it is basically based on languages such as JavaScript, HTML, and CSS providing a fine and extensible practice for command-line interface users. Hyper delivers a lot of its speed and functionality thanks to the power of term below, the terminal emulator of the Chromium project.
If you're just getting originated with Hyper terminal I'd suggest you head to Hyper website, they have an extensive installation guide and usage documentation

Artificial intelligence

Digvijay Karadia — Thu, 18 Nov 2021 09:41:08 +0000

Artificial intelligence is taking over the world. A day will come when you will just sit and relax and the machine does its job.

Artificial Intelligence is the mind demonstrated by machines that are opposite to that of natural intelligence, which is sometimes shown by animals and humans. The advanced professionals dealing with AI define it as, "A system that observes its surroundings and progress tentatively according to it with the maximum chances of achieving its goals." Some of them even use the term artificial intelligence to describe the machines that can copy the human mind and perform functions such as learning and problem solving, but this definition would have given AI a pretty critical view so it was rejected by Major AI researchers.

AI deals with every sector right now. The advanced search engines have AI attached to them. The recommendation systems, ads, and even in understanding the human speech and converting it into work (Alexa, Siri). Self Driving cars have AI, the voice searchers have AI. Computer games consist of AI and whatnot. I believe AI is slowly getting used to in the common world, making it easier for people to work with.
As machines have become increasingly capable, tasks thought to challenge "intelligence" are often removed from the definition of AI.

Fun Linux commands:-

Digvijay Karadia — Thu, 18 Nov 2021 09:39:15 +0000

The Linux command line can be the home of power users and sysadmins. However, Linux is more than just a lot of hard work. Linux was developed by fun-loving people who created an array of comical commands. Try playing around with these yourself when you want a smile.

Steam locomotive (SL)
For no reason whatsoever, you can cause a steam locomotive to zip across your terminal using the sl command. Install Steam Locomotive with your package manager. For example, on Fedora:
$ sudo dnf install sl

Real uses
As far as I know, the sl command is truly just for fun. Do you have an interesting use for sl? Let me know in the comments.

Fireplace (aafire)
Warm your heart and your terminal with aafire command, which causes a fireplace animation to play. You can install aafire with your package manager. On Debian, Mint, Elementary, and similar:

$ sudo apt install libaa-bin

On Fedora, CentOS, and others:

$ sudo dnf install aalib

fireside.png

Real uses
This image is a subtle way to communicate to your team or boss that everything's about to go up in smoke.

Yes
You can use the yes command to print out a string of text until it is forcibly stopped with Ctrl+C. For example, I am a Buffalo Bills fan, so I chose to print out an endless series of Buffalo Bills with the yes command:

$ yes Buffalo Bills

bills.png

Real uses
You can use this command to pipe confirmation to scripts so that when a script pauses to ask for confirmation, it automatically receives yes. For example, imagine there's a script you run that often stops to ask you for confirmation:

$ foo
Are you sure you want to do this? Y/n Y
Are you sure? y/N Y
But are you? y/N
You can auto-accept such messages bypassing yes to the command:

$ yes | foo

Alternatively, you can auto-deny messages using yes as well:

$ yes no | foo

Fortune
You can have your fortune told on the command line by installing Fortune. Fortune prints a random and possibly meaningful message.

Install Fortune with your package manager:

$ sudo apt install fortune

On Fedora:

$ sudo dnf install fortune-mod

The fortune command has many datasets it can draw from. For instance, you can get famous quotes from literature or the science-fiction TV show Firefly, or choose from jokes, tips about Linux, and much more. Search your repository for "fortune" to see what options your distribution provides.

$ fortune
Johnson's law:
Systems resemble the organizations that create them.
Real uses
You can use Fortune to generate a pseudo-random number. There's not enough entropy to make it cryptographically secure, but when you need an unexpected number, you can count characters or words:

$ fortune | wc --chars
38
$ fortune | wc --words
8
$ fortune | wc --chars
169
Lolcat
Lolcat is a program that concatenates files, or standard input, to standard output (like the generic cat) and adds rainbow coloring to it. You can pipe the output of other commands to lolcat, which provides a rainbow hue to the result.

Here's the result of lolcat -h for its help output:

Figlet and banner
The figlet and banner commands let you create simple ASCII text banners. Here's a text banner for a CentOS system:

$ figlet centos.com

figlet_centos.png
Text banner reading "centos.com" composed from symbols and characters

Pipe figlet to lolcat for a colorful banner:

$ figlet centos.com | lolcat

$ banner Hello World

A banner reading "Hello World" spelled out with pound symbols

Espeak
You can add speech capabilities to your command line funnies by installing espeak.

Once espeak is installed, turn up the volume on your computer and have some fun listening to your machine talk to you. Espeak is a software speech synthesizer, and there are a few different voice libraries available.

$ espeak "Linux is the best operating system."
