WEBVTT 00:09.220 --> 00:15.320 Hi welcome to the complete Ubuntu Linux server and recession goes in this lesson. 00:15.330 --> 00:19.330 We're going to learn the history of Linux operating system. 00:19.370 --> 00:25.350 Linux is an operating system Dolapo by Linus Torvalds in early 1990s. 00:25.610 --> 00:30.020 Linus is a graduate student from Union City office and key in Finland. 00:30.900 --> 00:39.340 In those days three operating systems were available in the market such as Unix DOS and Mac OS. 00:39.450 --> 00:46.770 The source code of Unix operating system was available for university students for study purpose but 00:46.920 --> 00:50.020 after some time this practice had been stopped. 00:50.070 --> 00:57.600 After that Professor Tannenbaum who was a news professor loves occlude North Unix operating system and 00:57.690 --> 01:04.980 named it as many Sagi which was used by new city students for understanding the working operating system. 01:04.980 --> 01:11.190 OK now those whose of Minix is available for all the students for understanding the internal working 01:11.250 --> 01:12.930 operating system. 01:13.050 --> 01:23.060 So Linus forward's get inspired by Minix and he loves the first official Linux kernel on up Google 1991 01:23.370 --> 01:25.980 and named it as Linux version. 01:25.990 --> 01:27.850 0 1 0 2. 01:28.180 --> 01:37.080 Ok this version contains three Kilties such as Basse update and this is the best use for executing the 01:37.080 --> 01:46.200 commands that is used for performing the operations of file and GCC that used to execute or compile 01:46.200 --> 01:47.410 the source code. 01:48.120 --> 01:57.990 Then on January 1992 Linux Widgeon zero point Clo was released as an improved and stable kernel of Linux 01:59.040 --> 02:06.090 that by a group of thousands of programmers around the world contributed to Linux and add their own 02:06.090 --> 02:10.970 source code under the new GPL to improve their operating system. 02:11.190 --> 02:12.830 What is the GPL. 02:12.840 --> 02:17.170 It is a general public license agreement and the vich you can add. 02:17.190 --> 02:23.670 You are all the source code to Linux cookie you can distribute it but you cannot sell that operating 02:23.670 --> 02:24.380 system. 02:24.500 --> 02:33.700 OK so under this license they contributed to Linux so and are different kinds of Linux distributions 02:33.970 --> 02:36.700 are done by different groups of programmers. 02:36.830 --> 02:44.010 OK distributions like redhat centaurs Debian Ubuntu and many more. 02:44.210 --> 02:48.220 OK though there are different solutions that are available. 02:48.400 --> 02:54.340 But one thing is common amongst all the distributions and that is the Linux kernel. 02:54.340 --> 02:59.480 It is the old operating system and our lives are different. 02:59.740 --> 03:06.140 So here I will issue your video order of Linux here working in his home office. 03:23.100 --> 03:25.010 So this is my working space. 03:25.470 --> 03:29.910 I've been using a working desk for the last three or four months now. 03:30.270 --> 03:36.780 I'm not sure how much it does for me but I'm sure it's healthier than just sitting down and also trying 03:36.780 --> 03:38.250 to keep my desk clean. 03:38.250 --> 03:44.760 Because if you pan over to my old desk which I don't actually use anymore because it got so filled with 03:44.760 --> 03:49.900 crap I didn't know what to do about this anymore. 03:49.920 --> 03:51.890 I need to burn it down some day. 03:51.900 --> 03:59.640 I used to work night time but then I got kids and the kids go to school and that means that we had to 03:59.640 --> 04:04.680 wake up at 7:30 or so to take the kids to school. 04:04.680 --> 04:11.460 It's not exactly a nine to five job but it is actually fairly close and you can see that in the commit 04:11.460 --> 04:12.050 logs. 04:12.090 --> 04:18.960 It's interesting I sometimes do statistics of how which time zones people are and what and what time 04:18.960 --> 04:26.160 people are working at and these days you can definitely tell that a lot of people are actually keeping 04:26.160 --> 04:27.420 pretty regular hours. 04:27.420 --> 04:31.860 I'm not the only one with kids career. 04:32.490 --> 04:34.850 It's set at a very slow speed. 04:35.430 --> 04:43.680 I call my zombie shuffling desk because if I put it any faster than 1 mile an hour my mouse movements 04:43.680 --> 04:47.180 get very erratic and I no longer can close my windows. 04:47.610 --> 04:56.130 I only have a web browser which is how I really email and a couple of terminal windows open which is 04:56.130 --> 05:04.690 where I end up doing my get tools and an encoding although the coding part is not that common anymore. 05:05.160 --> 05:13.650 In between emails I end up reading Mary's text sites and sometimes not so text sites depending on what's 05:13.650 --> 05:14.160 going on. 05:14.160 --> 05:17.480 I'm going to stop this because I'm having a hard time walking.
