Even today, the general consensus still stubbornly persists that Open Source software is developed by ponytailed computer geeks as a hobby in the middle of the night. It’s admittedly a very romantic notion, but one which only reflects the reality to a certain extent.
The Linux Foundation recently published a very interesting document on who actually contributes to the Linux kernel. Since 2005, some 11,800 individual developers from around 1,200 different companies have contributed to the Linux kernel. The fact that recently at least 88.2% of the improvements came from people who are also paid for this work – a growing trend – is proof that more and more IT professionals are also working on Linux.
