Linux - advanced open operating system, which is most often used not by ordinary users, but by specialists in the field of system administration. Thanks to the support of large companies (IBM, HP and others), the system has become incredibly popular in the field of server management. In addition to traditional computers, it is used on tablets, smartphones, routers, automation devices, TV control systems and game consoles. Having been created back in 1991, it still does not lose its relevance, and many enthusiasts work with it as their own instead of Windows and MacOS. Although its share of this target use is not high (1.21% as of 2015), it has no equal when it comes to system administration and server management. In addition, it has a huge number of capabilities that other systems lack.

My partner wrote about what we do). It must be said right away that working as a bioinformatician without Linux is practically impossible, since most bioinformatics programs are created specifically for this operating system and work only on it.

Due to the fact that this is an area at the intersection of sciences, we constantly communicate with biologists. Biologists now have to work with very large amounts of data, so the ability to use Linux, the optimal operating system for such tasks, is becoming a necessary skill. In fact, we are talking not only about the ability to handle Linux, but about computer literacy in general: what are the rules for working on a server, how to load and effectively store data files, what programs to run to process them and how to do this, etc. . - all those things that both simplify and speed up your work and greatly facilitate collaboration with colleagues. Despite the fact that you can figure out Linux on your own by reading smart books and websites, for people from a non-technical environment this often causes certain difficulties and many give up at the initial stages of mastering this OS (for example, getting acquainted with the command line).

Based on our experience, my colleague Andrey Przhibelsky (@andrewprzh) and I initially intended to conduct several classes on computer literacy for biologists. And then this idea grew into a three-week open online course (MOOC) from the Institute of Bioinformatics in Russian, which was later narrowed down to an introduction to Linux as a starting point - since it turned out to be very, very difficult to fit everything into three weeks. The course has already started and turned out to be quite popular (more than five thousand people have signed up for it at the moment), but the first deadline for assignments is November 24, so you can still join without losing points or just study the course in free mode (all materials will remain open).

If the community is interested, we will write a separate post about the preparation of the first online course in our life - it is not at all as simple and fast as it might seem at first glance.

But first I would like to dwell on the answers to the questions that we were asked most often. While preparing the course, we talked to a variety of people and were faced with the fact that many did not understand at all where Linux was used, and had no idea that the system could be useful to them. So:

Why do you need to know how to use Linux now?

Many people don't notice, but Linux is already around us. All Android devices run on Linux, most servers on the Internet also use this operating system and there are many other examples. Of course, you can continue to use all these things without knowing Linux, but once you master the basics of this system, you can better understand the behavior of the things around you. In addition, when working with large amounts of data, Linux is simply necessary, because most complex calculations on huge amounts of data are performed on computers running Linux. And this is not a random choice: most computing tasks are performed much faster on Linux than on Windows or Mac OS X.

How is Linux related to mastering other disciplines?

A huge share of scientific software, especially programs for processing big data (for example, in the field of bioinformatics) is developed specifically for Linux. This means that these applications simply cannot run on Windows or Mac OS X. So, if you do not know how to work in Linux, you are automatically deprived of the opportunity to use the latest scientific developments. In addition, by learning Linux, you will better understand how a computer works, because you will be able to give commands to it almost directly.

Why does this need a separate course?

Linux has a lot of features that are useful to know and, of course, be able to use them at the right time. Fortunately, modern versions of Linux are much more user-friendly than their counterparts 5-6 years ago. Now you don’t have to suffer for hours and even days and nights after installing the system to set up your Internet connection, printing on a printer, keyboard layouts, and so on. Anyone can start using Linux the same way they used Windows or Mac OS X after a minimal familiarity with this system, which will be calculated in minutes. However, the capabilities of Linux are much broader than “everyday” use. It is simply impossible to cover all the functionality of Linux even in a three-week course. However, we try to teach listeners to use most basic capabilities Linux, and most importantly, we hope that those who have completed the course will be able to successfully continue mastering Linux on their own.

What's interesting about Linux?

For us, Linux is like a very interesting book that you read and are happy to recommend to your friends and even feel envious that they still have an acquaintance with this work ahead of them. The only difference is that although we have been familiar with Linux for almost 10 years, we cannot say that we have “read” it in its entirety. You can always find something new for yourself in it, learn that many things that you are used to doing one way can be done completely differently - much easier and faster.

The more you get acquainted with Linux, the more interesting it becomes. And from the initial desire to “quickly turn off and reboot into the native and familiar Windows (Mac OS X)” you soon move into the state of “hmm, but this is not so bad” and a little later into “how could I even work in this Windows ?!” And while studying Linux, you can sometimes feel a little like a hacker or the hero of a movie about programmers =)

Our course consists of brief overview basic features of Linux, but for beginners this should be enough to get interested in Linux and dive a little into its philosophy. For example, we will spend most of the course working in the terminal, so beginners should get used to it and understand the advantages of this approach to managing a computer. For more advanced users, certain lessons of the course may be of interest - for example, about working with a remote server or programming in bash. .

How to check solutions to problems in a Linux course? Is it even possible?

The answer to this question was non-trivial - we thought for a long time about how to check tasks (for example, that the user installed Linux on his computer or edited a file in a certain editor) and how to come up with interesting tasks to really show real job with Linux. For some topics there were quite interesting approaches. For example, it was added specifically for the course new type tasks on the Stepic platform - connecting to a remote server (and opening a “terminal”) directly in the browser window - according to reviews from the first users, they liked it. Of course, the first time there were some rough edges, but overall, everything works quite well. A separate post from the developers will soon appear on the technical side of this issue. An example of such a task (to watch it live, you can sign up for the course):

It must be said that not all users perceived the tasks with humor. For example, we tested the skill of installing programs on Linux using the VLC program as an example. You had to install it on your system using one of the described methods, then open the help about the program, find the name of the first author and enter it into the verification form. We heard a lot of comments about this task :) And people made mistakes mainly in that they entered the first and last names, or just the first name, or part of the last name (and there it is double, with a hyphen!). In general, if you decide to take the course, then read the terms of the tasks more carefully and this will save a lot of time and nerves! True, there was a remark with the same author and to the point, it turned out that in older versions of VLC he is already in 14th place, so we added another author to the check, who is the first among the “old” list (and, by the way, the third in the “new” ).

Why is Linux so good?

The question is, of course, ambiguous. In my opinion, one of the key advantages of Linux over Windows or Mac OS X is that this operating system is developed by a huge community of programmers around the world, and not in two, albeit very large, companies (Microsoft and Apple). The source code of this system is open, and everyone can get acquainted with the internal structure of Linux or participate in its development. Developers are developing it not only for user-buyers, but also for themselves, which is why such great progress in development and many of its other advantages are associated. As "bonuses" for ordinary users: Linux is free, there are practically no viruses on Linux (and virus developers themselves often work on Linux!), there are a huge number of versions of this system and everyone can choose the one they like!

And finally, I would like to talk about my first acquaintance with Linux specifically in the work process (before that there was a separate course on studying, but I didn’t get much out of it, unfortunately). This incident impressed me so much that I still remember it. When I worked at the department at Polytechnic in my 3rd year, I needed to run one program for data processing. The program was written in C++, and we then worked in Windows XP. There were a lot of launches that needed to be done, they were pretty similar and usually took a couple of minutes. During this time, it was impossible to do anything else on the computer - it was completely frozen, so you could chat with other employees or just walk around the office. After about a couple of weeks of such launches, my supervisor advised me to try to do the same thing, but not in Windows, but in Linux. I then thought “well, what difference does it make?”, but I respected the manager so much, I recompiled the program and followed his advice. Imagine my surprise when I ran the same program on the same data and got the result (exactly the same, of course) in a few seconds! I didn’t even have time to get up from my chair, let alone take a walk...

By the way, in addition to our Russian-language online course on Linux, there is a good English-language introductory course from the Linux Foundation, which has already been written about on Habré. According to the website, it will start again on January 5, 2015.
