 Welcome to 25 years of Linux in just five minutes, so I'm covering quite a few years pretty quickly So I'll probably be talking faster than I'd like if you have any comments or anything during the presentation My Twitter handle is at Linux questions. They're more likely than anything else probably be corrections Brief intro for those you never familiar with me. My name is Jeremy. I'm the founder of Linux questions org I do a podcast called bad voltage with three other co-presenters and as Ricky said I am a Community moderator at open source comm. I also am on the board of the Linux fund So if you know any open source projects looking for funding do feel free to track me down in the hallway So if we're talking about the history of Linux right it starts with this guy Linus Torvalds And if you've been using Linux has anyone been using Linux since the beginning? A couple okay, so I've been using this since the beginning or you just have been into the history of Linux You probably are familiar with this post to use next right just a hobby won't be big and professional like a new What you might not know is he originally thought Linux was too egotistical He was going to call it free X which is a portmanteau of free freak and X. I think he made a good choice calling it Linux So moving on to 1992 This is the first GPL release and a lot of people don't know that Linux initially wasn't under a GPL license It was under a custom license that had some commercial restrictions on it and when he changed it to the GPL That's when you're starting this year first distributions in the next year In fact, you could slack we're in Debbie and still going Iggre Zill Which is what got me into Linux was released that year and that year we also get a hundred developers So you're seeing the uptake of Linux pretty quickly right from the beginning Now 94 you get the 1.0 release and this is when Linus felt that all components of the kernel were kind of fully matured But keep in mind these are still early days right the only machines supported our single processor I 386 computers A year later you get the 1.2 release and it's through some outside contributions You get some additional architectures are being supported and to 96 you get multi-process to support but more importantly I think we get this and this really is the initial idea Linux head for tux. Obviously, we ended up with this once again I think a better decision 99 get the 2.2 release What you see that up there might not seem interesting now at the time it was some pretty heavy pretty heady stuff But you also got this right This is Alan Cox for those of you not familiar and while in the 2.0 series a guy named Dave had been doing some late-stage maintenance and Alan had been doing the a series series This is the first time he passes mainline Linux off to another maintainer All right then in 2001 IBM pledges to spend a billion dollars on Linux just that year And that was a huge year for the commercialization of Linux that year You also get the 2.4 release which added a bunch of different technologies and you get a new maintainer in Marcelo Tossati Now in 2002 something important happens for the first time ever Linux moves to source control management Difficult to believe before a decade. He had done it manually through patches and email 2003 you get to 2.6 release But this is also the year that scope group files suit against IBM right and that really added a lot of uncertainty into the Linux ecosystem In 2004 and you're really starting to see the commercialization of Linux come upon and with that companies want cadence Right, they want to be able to schedule their products. They get that in 2004 with regular releases now in 2005 Due to some licensing issues with Bitkeeper and a little a bit of a fracah with Tridge Linux rights get and immediately moves all of kernel Development to that and as you know now get is very very popular 2006 you get the first long-term support releases. They're still around today. That's Greg K8. He still does some of them as well Now in 2009 you kind of see a little bit of a symbolic moment in the commercial Linux landscape It's the first time ever the market cap of red hat equals a market cap of Sun Which does is the largest commercial Unix manufacturer 2011 get the 3.0 release and there'd be 2.x had been going on for a while right and when someone asked Linux Why did you finally change from 2.x to 3? His answer was the big change was nothing absolutely nothing in 2012 this is a kind of another watershed moment for the commercialization of Linux and for the first time Linux server revenue sales equal that of the entire rest of the Unix market combined I was a little surprised it was this late to be honest a little bit ironically though the i386 Processors support and now remember the first release of Linux that was the only processor support was completely removed Now last year we had the 4.0 release and once again This was kind of a bit of a arbitrary version change But it did bring some cool things like live patching to mainline which brings us to today 2016 right hard to believe but the final resolution of the scale case just happened this year It's astonishing that it took that long, but there it is and over 13,000 developers from well over a thousand companies have contributed to Linux and that's just in see adoption of git Which is really when we can get meaningful numbers It's over 22 million lines of code right over three four five billion dollars to redo it Which is impressive but not quite as impressive at the fact that Linux really is everywhere from this watch to the largest Supercomputers in the world. It's everywhere That's 25 years of Linux in just five minutes
