I threw together a quick proof of concept for myself writing out a very simple Entity Component System (ECS) and implementing the flocking simulation on top of it. I liked how it came together so well I wrote some prose around it and decided to share. Note: this is using features from the soon-to-be-released 5.40.0 (RC1 dropped last Friday). submitted by /u/perigrin |
Birds that Flock Together
So I’ve been prepping for my class on Game Development and one of the things I want to introduce to people is the concept of an ECS (Entity Component System).Chris Prather (The Room)

(cdxcvii) 8 great CPAN modules released last week
Updates for great CPAN modules released last week. A module is considered great if its favorites count is greater or equal than 12. App...niceperl.blogspot.com
Hi! Asking for a wisdom here...
We have a module that modifies signal handler $SIG{__DIE__} to log information and to die afterwards. Hundreds of scripts relied on this module which worked fine in perl 5.10.1.
Recently we had the opportunity to install several Perl versions but unfortunately a large number of scripts that used to work with Perl 5.10.1 now behave differently:
- Failed in 5.14.4:
/home/dev/perl-5.14.4/bin/perl -wc
test.pl
RECEIVED SIGNAL - S_IFFIFO is not a valid Fcntl macro at /home/dev/perl-5.14.4/lib/5.14.4/File/stat.pm line 41
- Worked without changes in 5.26.3:
/home/dev/perl-5.26.3/bin/perl -wc
test.pl
test.pl
syntax OK
- Worked without changes in 5.38.2:
/home/dev/perl-5.38.2/bin/perl -wc test.pl
test.pl syntax OK
Many of the scripts can only be updated to 5.14.4 due to the huge jumps between 5.10 and 3.58; But we are stuck on that failures.
Was there an internal Perl change in 5.14 which cause the failures but works on other recent versions without any update on the scripts?
Cheerio!

My environment is perl/5.18.2 on CentOs 7
I'm trying to use a SWIG generated module in perl, which has a c plus plus backend. The backend.cpp sets an environment variable, $MY_ENV_VAR =1
But when I try to access this in perl, using $ENV{MY_ENV_VAR} this is undef.
However doing something like print echo $MY_ENV_VAR
works
So the variable is set in the process, but it's not reflected automatically since nothing updates the $ENV data structure.
I'm assuming it may work using some getEnv like mechanism, but is there a way to reset/ refresh the $ENV that it rebuilds itself from the current environment?

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?
