I know there choice of distro is really meaningless as you can install almost any program on almost any distro. But I have been playing with kali which is for security people and pen testers. Is there a similar distro for programmers? Like a few ides installed some profiling tools some virtual environment tools etc?
This isn’t technically true for all distros—Gentoo has a mechanism that will allow multiple package versions to be installed in parallel. I have multiple distro-packaged Python and Lua interpreter versions on my system, for instance. But it does require some extra work by the packager, so it isn’t done universally for all packages.
Are these made similarly to how Debian handles python2 and python3 for instance?
I’m not sure that anything short of a package manager that would compile everything from sources would be able to provide capability to pick and mix specific package versions.
I don’t know how Debian’s solution works, so I couldn’t say for certain. Gentoo usually installs the different package versions to their own directories, and there are methods for selecting a “system python” (or lua, etc) which is the target of the
/usr/bin/pythonsymlink. Other versions have to be called with qualifiers (for instance,python3.10). Python libraries installed through the package manager may install to one or several versions depending on the content of a couple of environment variables, and applications that need python can request a specific version if they need to, or accept the system python if they don’t care. (Note that python2 is no longer eligible to be the system python—you need at least one python3, although 2.7.18 remains in the package repository and can be installed as well if you really need it.)Of course, if you’re not a programmer, you can leave the defaults for everything alone, and most of the time it should Just Work.
