Fedora 31 : Can be better? part 004.
Another issue on Fedora can be linked to the management of transactions to avoid transaction lock.
Let's see how can be fixed:
Friday, January 24, 2020
Fedora 31 : The twa web auditor tool.
This tool comes with a good intro:
A tiny web auditor with strong opinions.
The tool named twa takes one domain at a time and use these dependencies: bash 4, curl, dig, jq, and nc, along with the POSIX system.
The project can be found at GitHub repository but I can be install easy on Fedora 31 distro:
TYPE(domain): explanation where TYPE is one of PASS, MEH, FAIL, UNK, SKIP, and FATAL., see the output example:
PASS: The test passed with flying color.
MEH: The test passed, but with one or more things that could be improved.
FAIL: The test failed and should be fixed.
UNK: The server gave us something we didn't understand.
SKIP: The server gave us something we understood, but that we don't handle yet.
FATAL: A really important test failed, and should be fixed immediately.
Another feature is scoring.
The score format is this: npasses nmehs nfailures nunknowns nskips totally_screwed.

Fedora 31 : Can be better? part 003.
Yes! The Fedora distro Linux can be better.
One bad problem for most Fedora users is video drivers.
I have an old NVIDIA graphic card: NVIDIA Corporation GT218 [GeForce 210] (rev a2).
This worked well with the nouveau device driver.
It will be great if the detection and install of the video graphic card will start from the installation process.
Another option is to have a dedicated opensource software for detection and installation of the video card.
