Linux Turns 30 - 9 Things You Might Not Know About Linux, If you want to find out..

 

 

hello I explained today the 25th of august the Linux kernel turns 30. 30 years since the initial posting by Linus torvills where he talked about his work on a free operating system and so here is my homage to Linux I want to talk about nine things that you may not know nine interesting facts about the Linux kernel so if you want to find out more Please let me explain that's on the 25th of august 1991 30 years ago Linus torvill posted for the first time about the free operating system he was working on didn't even have a name and then of course that became Linux and it was released under the GPL and that meant that lots of people could contribute to it knowing that their contributions would not just be sucked up by some private enterprise to build their own thing and benefit from all their work it meant that the source code was always out there which meant people were much more happier to lend their support to it and look into what it's grown into is absolutely huge dominant operating system that we use today so here are nine things you may not know about Linux nine things which I hope you find interesting number one is it runs on a whole wide range of CPU architectures of course it runs on processors from intel and AMD both 32-bit and 64-bit it also runs on arm processors and we'll talk more about that in a minute but it also runs on a whole bunch of others including risk 5 including alpha from deck for spark that was from sun microsystems a power pc of course from IBM  and the IBM's zed architecture for its mainframes it even runs on soft CPU cores that you can use inside of  gas it really has a real wide range of support and that itself is quite interesting because early on in Linux's history Linus was saying well I've only written this for the 386 it's going to be really hard to port it I'm using lots of features from the 386 and over time of course they were able to abstract some of that away and turn it into the Linux that we know and love today okay the second point is that Linux runs on super computers in fact there's a list of the top 500 supercomputers that is published to show the difference performance of those uh super goodies who's got the best super cool the top 500 supercomputer list and every single supercomputer on that list without fail runs Linux 500 of the supercomputers listed in the top 500 all around Linux no other operating system in sight now that is amazing now I said we talked about arm process of a minute and why did I say that because android itself uses the Linux kernel in fact if you think about it android's probably the most popular version of Linux out there it has got Linux kernel at its core and then of course on top of that google has built all the frameworks and things and services that we use today but at its very core it's running it that means billions and billions of devices that people are walking around in their pockets that they want that they're using every single day use Linux that is absolutely amazing and why did I say arm protocols because 99.99 of android devices use an arm based CPU of one kind or another but it isn't only things like smartphones and servers that use Linux it's used in lots of lots of other places some places you may not even know now I am a great fan of the amazon's kindle readers the kind of the monochrome e-ink displays in fact I've got a review of the latest one here on this channel I'll leave a blinky cardi thing up here somewhere and did you know that even that runs Linux so when you're reading a book on an amazon kindle whatever book it is that you're reading you are actually using Linux to do it now from time to time someone will write into one of the comments like I'm pronouncing Linux wrongly well actually I am not number five Linux is always pronounced Linux now of course Linus is his name Linus torvilles and Linus is a  name that's used in lots of countries around the world including Finland and Sweden and of course in lots of English-Speaking countries like the USA and sometimes it's pronounced Linus sometimes it's pronounced Linus but when it comes to Linux it's always Linux here's a quick clip from Linus himself explaining that very thing when I speak Swedish it's Venus when I speak Finnish it's Linos when I speak English it's Linus and I really don't care how people pronounce my name but Linux is always Linux number six Linux is not earthbound what do I mean by that because it's on mars so that helicopter that NASA have been flying around recently that is actually running Linux now while the rover itself is using a proprietary commercial operating system the helicopter is actually running Linux so Linux is literally out of this world I'm bringing us back down to earth to something that's much more familiar to us and that is gaming now valve has announced the steam deck I have a video here on this channel talking about what we can expect from the steam deck and the key thing about the steam deck is that it is running Linux and actually using some special software that valve has been uh promoting for a long time now called proton it's actually running windows only software windows only games on Linux through this compatibility layer called proton so when the valve steam deck actually hits the stores sometime later this year again another Linux device will be in people's hands doing some very sophisticated gaming now number eight is not about Linux itself but more about Linus Torvills did you know that Linus was not a one hit wonder in 2005 he wrote git and we use git today again all over the place git hub git lab at all that kind of stuff now what happened in 2005 is there was a problem with how the Linux source code was being managed Lannis wanted a new way to do it so he took a few weeks off and he went and wrote git the git that we use and love or hate maybe today and the interesting thing is it took him just 74 days from when he started writing it to win the first version of Linux that was released using his new software just 74 days absolutely amazing and let's close with a fun one number nine did you know that Linux includes a  bogus performance measurement for every CPU it's called BOGO MIPs of course is millions instructions per second it was very much a popular measure used a few decades ago to say how fast a process got today's equivalent might be tops and we talk about ai everyone's saying how many tops as it goes in one says it's pretty meaningless uh because you don't know what a top is you mean how many what is an operation what is it complex one is it simple one anyway that's a whole different discussion but inside the limits kernel they needed a way of measuring how fast the CPU was so that certain timings could be understood obviously something will take longer on some CPUs compared to another so Linus invented BOGO MIPs as I said BOGO as in bogus and so when the kernel boots up it will actually tell you the BOGO MIPs of your CPU and just to give you a kind of a measure a raspberry pi 4 might score 135 as its BOGO MIP whereas an AMD FX 8320 might score over 7 000. so go check out your BOGO MIPs and tell me in the comments below what does your CPU score okay that's it personally I'd like to thank lioness I'd like to thank not only him but there's so many other people that don't get recognized all the maintainers of the colonels the long-term support kernels all the people that have applied patches and all the corporations that have actually contributed to and fund Linux a big thank you to all of you because look at all the things it's doing everything from a kindle reader to a smartphone to a supercomputer to something on mars it's all running Linux okay that's it my name is Gary sims this is
