Class Notes

Linux was created by Linus Torvalds between 1991 and 1994
Linux is not a version of Unix
Once Linux was released to the public numerous institutions created their own versions of the operating system. These different versions are called Distributions, or Distros. Different Distros have different functionality.
Open Source software is not necessarily free software
Make sure you understand the licensing requirements for your Open Source software before you release it into a Production Environment.
Defining The Shell
The Shell is the interface you use to interact with the Operating System. Windows uses a GUI (Graphical User Interface) Shell, Linux primarily uses a LUI (Line User Interface)
ROOT is the highest level of anything in the Linux world. ROOT user is the highest level user. The ROOT directory s the highest level directory.
Capitalization matters in Linux (HOME is different then home)
Server vs. Desktop Versions
Server versions of Linux install the bare minimum number of components for the system to function. After installation you will be faced with a blinking cursor.
Desktop versions of Linux come prepackaged with a GUI environment and numerous tools and applications. After installation you will be presented with an environment that looks a lot like Windows or the Mac OS.
What Linux is really god for?
Linux is great for server functionality
Linux is still poor for every day desktop functionality for most users.

    Alejandro Rubio 3 года назад (изменено) +Tony Lizzerri Yes, but what's the point if he doesn't do his research before commenting. The desktop version of linux is used by million's. To tell people to use Windows 7 is not acceptable. clearly he doesn't use GNU/Linux on a daily basis.

  • Christyn Jackson
    Christyn Jackson 2 месяца назад @strontiumXnitrate entitlement? entitlement to what? basic decency and respect? i literally just pointed out that this sort of "women are illogical and cant be understood rationally" attitude is really common in the nerd circles that i frequent. i consider myself a nerd, i'm not stereotyping anyone, the people in the thread that i'm responding to literally said that. i just expressed that it's common and i'm tired of it. you way overreacted my dude.

  • strontiumXnitrate
    strontiumXnitrate 2 месяца назад @Christyn Jackson Grow up and stop projecting, princess. Nobody owes you a damn thing, not even male nerds you seem to hate so much. You have a misplaced sense of entitlement there, coupled with some strong sex-based stereotypes, and the result is as foul-smelling as one would expect: You are a bigot, a crybully whining while attacking others, declaring herself a victim while victimizing others. If you have been treated badly, it's because you are a horrible person and have earned it. Good luck improving yourself, you could use the improvement.

  • Christyn Jackson
    Christyn Jackson 3 месяца назад @Cameron Doyle was i talking to you? i don't think i was. saying a certain behavior is unsurprising is not the same thing as saying it happens in literally every case. i am saying it happens often enough that i am not remotely shocked by it anymore. if you were a girl who frequented nerdy spaces, from sci-fi to coding to philosophy, you would probably feel the same.

  • Dinil Gunaratne

  • jvsnyc
    jvsnyc 5 месяцев назад @lain That was certainly true originally, but there has now been so much done original, from scratch, for the first time, on Linux, that it is truly its own thing nowadays. People used to say *nix to include both, but now it just seems silly, besides not matching the regular expression including *inux.

  • Aaron Hill
    Aaron Hill 2 года назад I've been using computers for almost 30 years and that is the first time I have ever heard the term "LUI - Line User Interface", the far more common term, and arguably the more correct one, is "CLI - Command Line Interface".

  • Black Arrow Projections
    Black Arrow Projections Год назад To add onto what Eli said in this video, I've was running Ubuntu Studio 16.04 and it was really fast (OS resource use wasn't scaling with hardware increase too I found), but like he said there's still a trade off where stuff doesn't respond. Main issue was where it crashed on me twice where I couldn't get back into the os. Once was when my video card slipped out and nothing would show anywhere on reboot after I reconnected. I moved to windows 10 for the stability for studio development, but with more HP, windows is calling for over 5G ram to run the OS....Its like Eli said, Linux is built for techies, it needs help to be apple smooth

  • Ryan Mattox
    Ryan Mattox 2 года назад It's more like Linus made a kernel and then Stallman was like "Holy shit this is neat!" and decided to use Linus' kernel. We're still waiting on Gnu Herd to come out, but until then we should just call it Linux. It's a bit silly to name your operating system based on what's installed on it. It's like calling Windows Steam/Windows

  • Reivivus
    Reivivus 3 года назад Scientific Linux 7.2 is bae, especially if you are a bioinformatician desiring to do molecular dynamics simulations and phylogenetic tree construction. It also has a nice visual interface with not a lot of apps, but they are easy to install. It is somewhat hard to run Steam of Scientific Linux. I haven't been able to do it. But many applications can be installed with the "yum install ..." command where "..." is whatever program you want to install. It also has Microsoft Office linux equivalents pre-installed called LibreOffice.
