GNU is 35 years old
GNU just turned 35! If you don't know what GNU is, it can be briefly explained as a collection of computer software. All the system tools and software that Linux distributions use is GNU. For this reason, there are a lot of people that believe it is incorrect to say just Linux, but instead you should refer to it as GNU/Linux. After all, Linux is the kernel while the rest of the operating system is GNU.
I am not going to go into that discussion here, but what I am going to do is acknowledge that GNU is vitally important to the Linux family of operating systems, and one of the driving forces of the free, open source world. And from a programmers standpoint, I am infinitely grateful for glibc, although it should be noted that glibc joined the GNU family a bit later.
For anyone interested, the initial announcement of GNU from 27th of September, 1983, can be read at the official website for the Free Software Foundation.
