In the next 24 hours, there will be one big event happening, which is the release of Linux Kernel 3.0 by Linus Torvalds. He mentioned that on his Google+ account which was re-shared by many people and also recorded on GMANE.
Actually, it's not as big as the introduction of Linux Kernel 2.2 or 2.4 and even 2.6, but this new numbering marks for a new start for the whole Linux Kernel development even if there are no major changes happening inside just as Linus said before. It's more likely to kill the big number at the third position (or we would have 2.6.40 if Linus didn't cut that out).
By entering 3.0, Linux now plays an important role on many aspects of our life. Check out Business Insider's article about 12 Things You See Every Day That Wouldn't Exist Without Linux. I think they are all vital to human real life and that is a fact.
