Linux Founder Linus Torvalds: “I Don’t Really Love Other People. I Love Computers”

Do you know that the development of Linux was never started with the intention of making it an open source kernel? At the recent TED conference in Vancouver, Linus Torvalds revealed more interesting facts about his life and working style.

Linux kernel is the world’s biggest open source collaborative project. This would automatically trick your brain into thinking that the person behind the kernel would be someone who loves working with fellow programmers.

Well, proving you wrong, Linux founder, Linus Torvalds, admitted that he originally didn’t intend to make Linux open-source and began working on it as a solitary project. This happened at the TED (Technology, Entertainment and Design) conference in Vancouver.

“It wasn’t open source,” he said. “It was source that was open. There was no intention.”

“I’m actually not a people person. I don’t really love other people. I love computers,” the legendary software engineer Linus Torvalds said in an interview with Chris Anderson at the TED conference.

He accepted the fact that with time he has learned that having different people on a project is very important.

However, it shouldn’t be much shocking as Linus is known for his outspoken behaviour and occasional rants. In the interview, he was very open and revealed that he loves to work at home in an office.

“It is the most boring office you’ll ever see,” he said. “I often work in my bathrobe, and I have to have complete silence.”

When asked about his future plans or projects, he said he doesn’t have one. He said, “I don’t have an agenda” and he’s still happy working on Linux.

“I am not a visionary. I’m an engineer. I’m happy with the people who are wandering around looking at the stars but I am looking at the ground and I want to fix the pothole before I fall in.”

Another fact we came to know at the talk: Linus Torvalds considers Thomas Alva Edison greater than Nikola Tesla. Sorry, Larry Page and Elon Musk!

10 Reasons : Why should we use Linux? | Padsa Information

Bored using windows or any other server in your computing experience? Linux has been designed to offer you smooth and effective experience. Whether you want to use it for business or any other home operations, Linux offers the most reliable system to adopt. Linux has become one of the most adopted systems by many users in and around the world. Most of the world’s largest data centers across the globe use Linux. There are various reasons that answer why should we use Linux, keep on reading.

Why Should we use Linux?

1. Linux is free of charge and in case you still doubt, then know that it is.

In case you want to get rid of all the restrictions in terms of patents of any other form of restriction, then this would be the best switch for you. Linux can be edited in terms of the source code by most of the innovative business owners. It is, therefore, the best system to be adopted by a large number of business owners who want to simplify their business operations.

2. Linux is more secure than any other server

Linux is a dependable server that offers excellent security to the user. Linux community offers the security fixes for any technical or security threat that encounters. Moreover, Linux users also offer regular kernel updates and regular security patches. In this regard, it is not mandatory for you to have an anti-virus program for your system. With Linux, you can save a lot of dollars you could have spent buying an antivirus program.

3. It has a wide compatibility to several hardware

Most of the other servers do constraint you with a lot of features. Take for instance windows 7 and 8 do require at least 1GB RAM for your system to operate well. However, Linux is such a lightweight operating system and hence does not constrain you in terms of a memory capacity of your system. It can thus be used by any of your systems. It is designed for everyone and can be used by anyone.

4. Easy to Operate

Ideally, one does not have to go for intensive training for them to know how to operate Linux operating system. Besides, it comes with all the necessary functionality that is included in windows OS. If you are looking for a system that is reliable and can be used by anyone in your business, then this could be the best system to adopt.

5. It comes inclusive of drivers

Ever experienced some difficulties when using windows only to be told that some of the drivers are missing in your system? Linux saves you a time you have to spend moving from one shop to another for drivers. It saves you money as well. Most of the drivers are included in Linux operating system. No need to hassle and stress for drivers.

6. Smooth and easy Updating Process

Updating windows can be very challenging and stressful. Linux updates both the OS and the applications that are installed in your system. Besides, when compared to windows that need your system to shut down Linux updates are just a matter of click.

7. Linux is speedy

Since Linux is lightweight, it is therefore far much speedy compared to any other operating system. Windows has a bloated software and therefore huge to operate. In any business operation or gaming experience, time is the most crucial factor. Linux is the best system to adopt as windows get slower days after days.

8. Linux has a community support

One of the best things about Linux is the fact that you have a sense of belonging. You have a platform where you can share everything with fellow users. You get to know more through the frequently asked questions. Moreover, any question that you have can be dropped and get the answers that you need.

9. Linux features a powerful word processing program

Libre Office is a powerful word processing program that comes with Linux. You can use it for free in editing, opening and send Microsoft documents. You, therefore, save more and more dollars you could spend buying such a program.

10. Linux offers you a chance to download a lot of free tools

By just a click of a button, you can get access to thousands of tools and programs. This is a big added advantage over the windows operating system. It is the best way to transform your serving experience.

How To Pick Your First Programming Language (4 Different Ways)

Learning coding from scratch could be a tough task and it could take years of hard work to master a language. So here I am going to address the biggest problem a beginner faces: How to pick up my first programming language?

Recently I came across with a very enriching infographic that addressed the same question. Udacity has utilized the date of the top ten programming languages in the US (provided by IEEE Spectrum) to pick the best programming language for you as a beginner.

The basis on which this infographic is made varies from location, your lifestyle and the potential growth in career after selecting that particular language.

Based on the flexibility, Python or C++ comes first as it allows you work on the variety of fields such as gaming to making of embedded systems. JS or PHP prepares you for a web development career. Similar observations and trends are made based on the average pay per year, geography and popularity.

How to Clear Your Terminal History on Linux or macOS

Press the “up” arrow in the Mac or Linux command line and you’ll see the last command you ran. Keep pressing “up” and you’ll see more commands; you can go back days, months, or even years.

This is called your history, and it’s very convenient. If you made a mistake typing a long command, simply press “up” and fix the problem. If you want to re-connect to an SSH server you used the other day, simply press “up” until you see the relevant command.

It’s useful, but there’s also a potential security problem here, particularly if you accidentally typed a password in plain text at some point. How does one clear this history? Long story short, you can do so with two commands: history -c, followed by rm ~/.bash_history. Here’s what those commands do, for greater clarity.

Clear the Current Session’s History

Your history can be broke down into two chunks. There’s your current sessions’ history, and there’s your long-term history. Our first command, history -c, deals with the current session.

The history command is built into Bash itself, and the -c modifier tells the program to clear that history. This command will prevent anything in your current session from being written to your long-term history, but does not clear out that long-term history.

Clear All of Your Bash History

If you want to remove the entirety of your history, run the following command:

rm ~/.bash_history

If you don’t know, rm is a longstanding command for deleting files in UNIX-based systems. ~/.bash_history is a simple text document, which stores you Bash history.

Alternatively, you could open the file and delete any lines you’re concerned about. On a Mac, type open ~/.bash_history and your default text editor will open the file.

On Linux systems, replace open with the name of your preferred text editor, such as nano, vim, or gedit. One you’ve opened the file, you can delete any lines you’d rather not keep by hand. Save the file, then restart your shell, and the lines you’ve deleted will stop showing up.

Clear Your Terminal for a Like-New Session

This one is mostly unrelated, but I’m mentioning it anyway. The command clear makes your Terminal look like you just opened a new session, which is useful if you take a lot of screenshots and want things to look tidy (or don’t want people over your shoulder to see what commands you’ve been running.)

This is entirely aesthetic: scroll up and you’ll still see your previous output. But if you’re in my line of work, it comes in handy.

While the first time users can grab the ISO images and torrents from Arch’s website, the existing users can update their systems using `pacman -Syu.’

Arch Linux installation isn’t something that involves simply clicking next and skip buttons. It includes multiple steps like partitioning the hard drive, formatting them, enabling swap, mounting partition as root file system, and manually downloading and installing the base OS. The user also needs to run various commands for setting up various things.

There’s no denying the fact that getting an Arch Linux machine up and running needs a little more time and commitment — as compared to other Linux distributions like Fedora or Ubuntu. But, this practical approach teaches you many things and it appeals lots of hardcore Linux enthusiasts.

Arch Linux 2017.01.01 — first ISO spin of 2017

As a great news for Linux enthusiasts, the first ISO snapshot, i.e. Arch Linux 2017.01.01, has been made available for download. This means that the devs have been working hard in the holidays to bake this Linux treat.

Contrary to what many of you would’ve expected, Arch Linux 2017.01.01 is powered by Linux kernel 4.8 series, version 4.8.13 to be precise. The size of the latest ISO image is 867MB.

As this image is intended for the new installations only, the users can burn this on a DVD, mount it as ISO, or write it to a USB drive using some utility.
