for programmers . kali linux or debian ... ?

Question

or somthing else

Answer 1

Between the two you mentioned. I choose Debian.

Although you can technically code in Kali, this is frowned upon because Kali is built primarily as a pentesting distro. The official website of offensive security even mentions that Kali was NOT built as a desktop distro.

Read the documentation:
https://docs.kali.org/introduction/should-i-use-kali-linux

You can also try Ubuntu as an alternative to Debian. I haven't tried any RHEL-based distros but you can also try Fedora if you want.

Answer 2

I would suggest you kaLi Linux but programmer can code in every OS.
