The AppImage tool and Krita Next.

The AppImage is a universal software package format.
The process of packaging the software in AppImage is a storage file provide by the the developer.
This file is a compressed image with all the dependencies and libraries needed to run the desired software. The AppImage doesn’t really install the software just execute it without no extraction and no installation.
The most common features:
  • Can run on various different Linux distributions;
  • No need of installing and compiling software;
  • No need of root permission and the system files are not touched;
  • Can be run anywhere including live disks;
  • Applications are in read only mode;
  • Software are removed just by just deleting the AppImage file;
  • Applications packaged in AppImage are not sandboxed by default.
More about this can be read at official webpage.
I tested the Krita Next with this tool.
The appimage file of Krita Next can be found here.
About the Krita Next this is a daily builds that contain new features, but could be unstable.
After I download the file I change it to executable with:
[mythcat@desk Downloads]$ chmod +x krita-4.2.0-pre-alpha-95773b5-x86_64.appimage 
[mythcat@desk Downloads]$ ./krita-4.2.0-pre-alpha-95773b5-x86_64.appimage

Fedora 29 : The figlet linux tool.

About this Linux tool you can read at figlet manual :
FIGlet prints its input using large characters (called ``FIGcharac- ters'')made up of ordinary screen characters (called ``sub-charac- ters''). FIGlet output is generally reminiscent of the sort of ``sig- natures'' many people like to put at the end of e-mail and UseNet mes- sages. It is also reminiscent of the output of some banner programs, although it is oriented normally, not sideways. 
...
Let's see some examples:
[root@desk mythcat]# dnf install figlet
