Im working on a script to test using a jump server to reach remote devices.
I'm able to connect to the jump server using Net::SSH::Expect, however, I'm not sure how to then ssh to a remote device (network element).
Is there a way to create that ssh to the remote device inside the jump server's connection?

First things first, I am a data engineer but have little experience in Perl. I've been able to make some easy updates to scripts in the past but this one is a bit tougher.
I have been asked to update a Perl cgi web app that someone wrote ages ago that is used to view and manipulate text files. Currently it is hosted on server (X) and manipulates the files on that same server. However, we have to have backups/mirrors of the data on a dev server and another prod sever (Y). I.e., if I push the button to move the file to a different folder, it should do that on all three servers instead of just X ..read more

I stumbled upon this really nice page from Ruby, describing the language from the perspective of other common programming languages:
https://www.ruby-lang.org/en/documentation/ruby-from-other-languages/
The page is written in a friendly tone, inviting programmers familiar with other programming languages to Ruby. No programming language is being viewed as inferior, quite the contrary: all mentioned languages are praised and even defended from haters, for example:
"Perl is awesome. Perl’s docs are awesome. The Perl community is … awesome. For those Perlers who long for elegant OO features bui ..read more

my $MAX_PROCESSES=10; my $pm = Parallel::ForkManager->new($MAX_PROCESSES); while (1) { my $pid=$pm->start and next; print "$$ LOCK \n"; $pm->finish; } $pm->wait_all_children;
I made this sample piece of code which I basically took from the docs, I only changed to infinite loop but I cannot understand why this would make any different between an infinite loop and iterating through an array for example? Anyway I am fighting this for several hours now trying different versions of my code and cannot find why am I getting "Cannot start another process while you are in the child proc ..read more

Prior releases of the 6.x line relied on Lexical::Types, which was a major performance pessimisation over the 5.x releases.
6.0.4 relies on a simple source filter instead, which restores performance levels back to expected levels.
More benchmarks added to the test suite validate the dependency changes.
