Does #gnuplot project <http://www.gnuplot.info/> not believe in providing SHA(512|256) checksums of download files? Or, PGP/GPG signature of the file (along with public key)?
The downloading behaviour on #SourceForge <https://sourceforge.net/projects/gnuplot/files/gnuplot/5.4.10/> <https://sourceforge.net/projects/gnuplot/files/gnuplot/5.4.10/gnuplot-5.4.10.tar.gz/download> in itself creeps me out for having a fucking redirection. Why.
And I just realized that the project website itself uses "HTTP" without the "S". Yeah
I would not have to look into installing v5.4.10 on someone's request if it was available as a package for #RockLinux 8 that work has in use.
It has not moved to v9+ due to lack of support for NIS; moving to LDAP is planned in 1+ years.
