From Wikipedia, the free encyclopedia
Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).
Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

I have to agree with the positivism surrounding Kate. It has been the only one (together with KDevelop) out of the 5 text editors I've installed and tested since yesterday that actually did what I desired from it. Props to the devs! Let's see if it can dethrone Emacs 😜.
Emacs will always be abe to do things you can't do with other editors. It's a text based interface toolkit that happens to also have a good text editor and IDE capability. Buuut, you need to spend a lot of time to set things up. I use it since probably more than 20 years and I still often need to look up and learn stuff. If you want a tool and not a workshop, get a simpler editor.
