Why I Like Perl's OO
I started programming with QBasic and later C. While it was difficult to learn those languages back then (with no internet and just some books) nothing felt “out of place” for me.davidraab.github.io
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. I added code to do this, referencing the additional servers with their UNC names, but I just get an error "No such file or directory" (which is not true). Googling has suggested that there may be an issue with permissions, but I can bring up the Y and DEV servers from a windows file explorer using the same path so I don't think that is necessarily the issue.
Example: Here we are trying to copy the file with a letter appended a given number of times. It works fine on the X server, its when trying to make it also work on the Y and DEV servers I get an error.
our $DIR_X = "\\\\serverX\\folder\\subfolder" ; our $DIR_Y = "\\\\serverY\\folder\\subfolder"; our $DIR_DEV = "\\\\serverDEV\\folder\\subfolder"; . . . }elsif ($query->param('action') eq 'split' && $query->param('fileNum') ne "") { my $fileNum $query->param('fileNum'); my $fileX=$DIR_X . "\\" . $fileNum . ".txt"; my $fileY $DIR_Y . "\\" . $fileNum . ".txt"; my $fileDEV = $DIR_DEV . "\\" . $fileNum . ".txt"; my $splitNbr = $query->param('splitNbr'); my @letters1("a".. "z"); for (my $i = 0; $i < $splitNbr; $i++) { my $FileNew_X = $DIR_X . "\\" $fileNum. $letters[$i]=.txt"; my $FileNew_Y = $DIR_Y . "\\" $fileNum. $letters[$i]=.txt"; my $FileNew_DEV = $DIR_DEV . "\\" $fileNum. $letters[$i]=.txt"; copy($fileX, $FileNew_X) or die "WARNING: copy failed: $!\n"; ---->>>>>ERROR AT NEXT LINE copy($fileY, $FileNew_Y) or die "WARNING: copy failed: $!\n"; copy($fileDEV, $FileNew_DEV) or die "WARNING: copy failed: $!\n"; }
Any thoughts?

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 built-in from the beginning, Ruby may be for you."
- "Happily, it turns out that Ruby and C have a healthy symbiotic relationship. And, of course, Ruby itself is written in C."
- "Java is mature. It’s tested. And it’s fast (contrary to what the anti-Java crowd may still claim)."
- "Python is another very nice general purpose programming language."
I believe Perl could greatly benefit from having a similar page. With its friendly philosophy and TMTOWTDI, it seems natural to invite programmers from other languages, with an approach of "Don't be afraid to keep programming the way you are used to, if it works in Perl, there are no limits enforced".
Since Perl is now not a common choice for new code or for learning, it makes a lot of sense to bring over people from other languages. Especially in an age where strict conventions seem to be praised, I can see Perl becoming a source of some fresh air.

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 process" all the time, any hints appreciated
output looks basically like this
Cannot start another process while you are in the child process at .... 16366 LOCK 16367 LOCK 16368 LOCK 16369 LOCK 16370 LOCK 16371 LOCK 16372 LOCK 16373 LOCK 16374 LOCK 16375 LOCK Cannot start another process while you are in the child process at ....

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.

Changes for 0.04
- Allow negative values to be passed to bitwise operators (&, |, ^, ~, >>, <<). These negative values will be converted to their 113-bit 2s-complement value prior to being acted upon by the bitwise operator - thus mimicking perl's treatment of negative 32-bit/64-bit IVs.
- Add divmod() function.
- Add new test file t/bitwise_feature.t

HTTP/2 Dynamic Benchmarks (PHP vs. ModPerl2), 2024 edition.
I ram these about four years ago, and the time differentials were about the same then as now. Monolithic POSIX-threaded server architectures like mp2 + mpm_event will always dominate in low-latency/scalability HTTP/2 benchmarks because they leverage zero-copy in the runtime.
Anyways, sexy terminal graphs with smag to enjoy!

Lessons learned: A) Performance freaks to stop using #rstat 's runif for random generation. The Hoshiro random number generator https://arxiv.org/abs/1805.01407 is 10x faster. Implementations in #perl 's #PDL, #rstats (dqrng) and #python #numpy are within 20% of each other B) But does it make a difference in applications? To get to the bottom of this, I coded a truncated random variate generator in #rstats and #perl using #pdl (as well as standard u/perl) using the #GSL packages https://metacpan.org/pod/PDL::GSL::CDF & https://metacpan.org/pod/Math::GSL for accessing the CDF & quantile functions. In this context, it's the calculation of the #CDF that is the computationally intensive part, not the drawing of the random number itself. C) I should probably blog about these experiments at some point. Note that #pdl (but not base #perl) are rather competitive choices for large array processing with numerical operations. I mostly stay away of #python , but would not surprise me that for compute intensive stuff (where the heavy duty work is done in C/C++), it does not matter (much) which high level language one uses to build data applications submitted by /u/ReplacementSlight413 |
