Linux is washing powder! 10 interesting things about Linux

Time:2021-12-4

Today, the Linux operating system drives supercomputers, bullet trains, Hollywood movies, submarines, the international space station, the New York Stock Exchange, and so on. However, there are many thought-provoking and amazing facts about the birth and journey of Linux.

1. Linux was born as a directory name
For those who didn’t know, Torvalds originally named his kernel “freex” – a combination of “free”, “freak” and “X” (implying Unix).

When his colleague ARI lemmke (who was one of the volunteer administrators of the FTP server at that time) uploaded the kernel to the FTP site, he didn’t like the name. He created a subdirectory for the source code and renamed it Linux without asking Torvalds.

2. Tux is named after Torvalds
When the mascot was named, Torvalds couldn’t find it, so the developers launched a competition to name the penguin in Linus’s absence.

Here are Torvalds’ favorite Penguin photos, which are the inspiration of tux.

James Hughes was the first person to call a tuxedo. According to him, this is the acronym of Torvalds UNIX.

The first known attempt to name “the penguin” was found on this email:

Let’s name the penguin! (was: Re: Linux 2.0 really is released..)

Ok, I took the plunge, and Linux-2.0 is out there on the normal
sites. I even got the energy to write some inane announcement
about it on cola, so it’s too late to chicken out any more.
So it’s the ‘Electrified Penguin on Cola’ release? πŸ˜‰
Anyway: Congratulations for this great achievement.
Let’s start the ‘We name that penguin while Linus is not around’ contest.
I vote for ‘Homer’ (Of course) πŸ™‚
Ciao

The following reply seems to be the first time to use the name “tux”:

(T)orvolds (U)ni(X) –> TUX!
This provides an explanation for the name.

3. Torvalds no longer writes code
By 2021, less than 1% of the Linux kernel will be written by Torvalds himself. Today, Linux is supported by more than 20000 contributors from more than 1500 companies.

Yes, Torvalds has written the initial code for Linux, but now you won’t find him writing code.

I write very little code these days, and I haven’t written it for a long time, because all my real work is spent reading and writing e-mail. It is mainly about communication, not coding.

LINUX TORVALDS

When Linux Torvalds launched its first kernel, it had only 10250 lines of code and occupied only 65 KB. In contrast, Linux currently has more than 27 million lines of code.

4. Hidden dates in the Linux kernel
Now let’s discuss the variables and their values in the reboot. H header file in the Linux kernel source code library. Did you know that there is an Easter egg hidden in the Linux reboot() system call?

Some checks are made on the reboot () system call to prevent it from being called incorrectly, because after all, you don’t want to accidentally restart the system. There are two parameters labeled Magic1 and Magic2. The first one is very simple — it accepts only 0xfee1dead. However, Magic2 can have four potential values – 67227479385072278369367448 and 537993216

Converting these numbers to hexadecimal will reveal some interesting things.

28121969 (28-12-1969) – Linus Torvalds’ birthday.

5121996 (5-12-1996) – Linus’s first daughter’s birthday.

16041998 (16-04-1998) – Linus’s second daughter’s birthday.

20112000 (20-11-2000) – Linus’s third daughter’s birthday.

In the United States, the correct way to write a date is mm-dd-yyyy. However, outside the United States, they are often written as dd-mm-yyyy. As you know, Linus is not a Native American. He was born in Finland.

Now everything is clear. Linus chooses to add some of his own elements to the system call.

5. Steve jobs offered Linus Torvalds a job
In 2000, Steve Jobs invited Torvalds to work in Apple’s Cupertino Park, on the condition that he should give up Linux development and start working in non Linux. Torvalds will get a good salary and excellent position in the organization.

UNIX for the largest user base: This is propaganda.

LINUX TORVALDS

Torvalds apparently refused. And Torvalds doesn’t like MAC kernel mach. He prefers to work hard for his dream.

6. Apache HTTP server soars the popularity of Linux
Apache, one of the oldest web servers, is still running and receiving updates. According to the Apache foundation, it was developed 26 years ago, so it provides rock solid performance and legacy support.

If you track the adoption curve of Linux, you will find that many early companies used linux because of the Apache HTTP server. This is also the same period when websites became business tools. Therefore, the main reason for individuals and companies to embrace Linux in the good times of the past is the Apache Web server.

7. The US military likes Linux
Considering national security issues, the implementation of Linux seems to effectively meet the key security requirements of the U.S. government for application development and installation.

The U.S. Army is the largest single installation base of Red Hat Linux. The U.S. Navy’s nuclear submarine fleet runs on Linux, including their sonar system.

In addition, Linux is now certified to meet three different security certifications required by the U.S. Department of defense.

8. Hollywood moves towards open source
For most of the past 30 years, Hollywood has led the development of computer graphics by continuously promoting the most advanced technology and amazed the audience with more spectacular visual effects.

One of the secrets of Hollywood blockbusters is that it uses Linux to provide their movies. Making Linux an attractive choice for a high-profile media studio is not just low cost. Its unparalleled performance can easily surpass that provided by Apple or Microsoft.

Titanic, released in 1997, is the first major movie to render most of its effects under Linux – using a rack type high-performance Dec alpha based server. At this early stage, Linux still plays its traditional role as a back-end server.

Now, large studios such as Disney Pixar, Sony or DreamWorks use mainly Linux based working machines to create their visual effects or animations.

But this is not a story about one or two studios adopting Linux. We’re talking about the whole industry. In other words, all large film studios mainly use Linux for animation and visual effects.

9. Microsoft’s contribution to Linux kernel
This is correct. This company with proprietary software development as its main concept has also contributed to Linux. As you know, Microsoft Windows and open source Linux operating systems have been the opposite for decades.

Today, Microsoft is not only a member of the Linux foundation, but also a member of the Linux kernel security mailing list. The Redmond technology giant first began contributing to the Linux kernel in 2009. Microsoft is submitting patches to the Linux kernel to create a complete virtualization stack with Linux and Microsoft hypervisors.

Today, you can run Linux applications in windows because of a feature called Windows subsystem for Linux. In addition, Microsoft engineers continue to increase their contribution to the Linux kernel, which is of commercial significance to them, for example, in the case of protecting the azure cloud.

10. Linux is an authentic detergent brand

Let’s end with an interesting fact. Linux is also a genuine detergent brand in Switzerland. There is a washing powder company with the same name as the kernel created by Linus Torvalds.

This is a famous brand of washing powder. It not only produces washing powder, but also produces liquid detergent, washing care, washing liquid, dishwasher, etc.
