WEBVTT 00:00:06.825 --> 00:00:10.825 Computers, I've loved them since I've been able to afford to have my own, 00:00:11.164 --> 00:00:15.144 back in the beginning of the modern home computer era - in the 1980s. 00:00:15.720 --> 00:00:19.430 And I've owned a large number of different kinds of computers 00:00:19.581 --> 00:00:23.771 and I've expressed, publicly, loyalty to this kind or that kind, 00:00:23.951 --> 00:00:26.855 but recently my mind has turned, as many people's have, 00:00:27.105 --> 00:00:30.835 to this whole business of free software. 00:00:32.070 --> 00:00:35.070 If you have, I don't know, plumbing in your house, 00:00:35.428 --> 00:00:37.568 it may be, that you don't understand it. 00:00:37.760 --> 00:00:40.330 But you may have a friend who does and they may suggest 00:00:40.431 --> 00:00:42.578 you move a pipe here, or a stopcock there 00:00:42.809 --> 00:00:44.729 or a valve somewhere else 00:00:44.944 --> 00:00:47.664 and you're not breaking the law by doing that, are you? 00:00:47.774 --> 00:00:50.284 Because it's your house and you own the plumbing. 00:00:50.563 --> 00:00:52.323 You can't do that with your computer. 00:00:52.431 --> 00:00:55.641 You can't actually really fiddle with your operating system, 00:00:55.740 --> 00:00:59.391 And you certainly can't share any ideas you have about your operating system 00:00:59.391 --> 00:01:00.781 with other people. 00:01:00.892 --> 00:01:06.364 Because Apple and Microsoft, who run the two most popular operating systems, 00:01:06.471 --> 00:01:10.051 are very firm about the fact that they own that. 00:01:10.176 --> 00:01:13.506 And no one else can have anything to do with it. 00:01:13.863 --> 00:01:16.413 Now this may seem natural to you, why shouldn't they? 00:01:16.616 --> 00:01:17.836 But actually, 00:01:17.993 --> 00:01:20.053 why can't you do with it what you like? 00:01:20.053 --> 00:01:22.883 And why can't the community, at large, 00:01:22.883 --> 00:01:26.283 alter, and improve, and share? 00:01:26.283 --> 00:01:28.798 That's how science works, after all. 00:01:28.914 --> 00:01:32.914 All knowledge is free and all knowledge is shared in good science 00:01:32.938 --> 00:01:36.798 If it isn't, it's bad science and it's a kind of tyranny 00:01:36.961 --> 00:01:40.161 And I'm here, as it were, simply to remind you 00:01:40.216 --> 00:01:46.980 that GNU and Linux are the twin pillars of the free software community 00:01:47.127 --> 00:01:50.301 People who believe -and this is the important part- 00:01:50.301 --> 00:01:55.557 that software should be free, that the using community should be allowed 00:01:55.557 --> 00:02:00.198 to adapt it and adopt it, to change it, to improve it, 00:02:00.397 --> 00:02:03.180 to spread those improvements around the community 00:02:03.223 --> 00:02:05.768 like science. That's basically what it's saying 00:02:05.768 --> 00:02:09.398 In the same way that good scientists share everything, and all knowledge is 00:02:09.398 --> 00:02:13.398 open and free, so it should be with an operating system. 00:02:20.999 --> 00:02:30.659 [Trade-free means good practice]
