The Linux Foundation is preparing to celebrate the 20th Anniversary of Linux, and in so doing has produced an infographic charting the state of Linux in the past and how it has progressed to its current, healthy state. You can click the image below to see the full-size version and take in the stats.I think you’ll agree that there’s some very positive growth that’s occurred over the last two decades. The kernel code has grown from 250,000 to over 14 million lines of code, and thankfully the developers supporting it has grown significantly to help maintain it. Can any other operating system count 1,000 core developers pushing it ever forward?One of the most telling stats, based on information gathered from LinuxCon registrations this year, is how the different distributions have won or lost favor with users. Although Fedora used to hold nearly half the market share (45%), it has now dropped firmly into second place (28%) behind the growing popularity of Ubuntu (34%). One positive aspect of this change is more distributions are getting users’ attention and use, and Linux Mint has recently joined the more well-known and older distros on the list.As for where we use Linux the most, at home used to take the top spot, but with a growing reliance on Linux in the workplace, either being used directly or on servers for cloud computing, business use now comes top. Surprisingly, use of Linux in schools doesn’t seem to have changed and accounts for just 7% of total users, something that really needs to change, and possibly will once the $25 PC is made available.Although these stats are based on the feedback of people already interested in or using Linux, it’s still a timely reminder that Linux is prevalent throughout the computing world 20 years after it first appeared. Even if you’ve never sat down at a PC and used Linux as an OS directly, chances are you come into contact with it every day just through surfing the web, paying for your shopping, running a wireless router at home, or by owning and using an Android device. That isn’t set to change any time soon, in fact the usage of Linux, and the Linux kernel especially, is only going to grow.Click to see the infographic full-size.
