Python is one of the worst performers (and Java is shockingly bad too, although a lot of that is down to the way the JVM/language have been mismanaged). At least unless you're comparing it to very low-level languages (VDL, C).
This is interesting and not what I would expect. Generally to get a java app running from github you'd install the correct JDK and that should be about it. Many projects will use maven, which will know how to obtain dependencies. Could you describe a typical issue?
That and the whole JVM fragmentation and not being able to touch Oracle because it's Oracle and they'll use it as an excuse to sue you (at least that's the impression I had, the entire lawsuits thing is why I left Java back in the day).
You can say the same about other package managers, but it's not very often that I have to add another source to apt unless I'm running in a locked-down environment.
No it doesn't. That's only if you're dealing with private maven repos and authentication etc. You don't need to do that at all for the use case in this thread, running a project from github.
Or the Go compiler fragmentation, where only the reference compiler supports everything, tinygo a subset, and gccgo left to die in Go pre-generics era.
sudo apt-get install <jdk>
sudo apt-get install maven
That isn't really a problem with other languages.
For languages/tools/frameworks/whatever that I'm already using, the main way I compare between them is looking at the ratio of "problems I was able to solve from their official documentation" vs "problems where I needed to use random blog posts (or worse, Stack Overflow) to find the solution".
Makes it a lot easier for me to choose tech for my hobby projects, where I sometimes don't even touch projects for several years because stuff just runs smoothly.
