Christos Argyropoulos, MD, PhD. (you know him here!) is our moderator for this virtual event, which is December 18th, 2024 - Perl's 37th birthday! At this event we will be announcing our Summer 2025 plans, which will include a 3rd Issue of the SPJ.
We have author 6 committments from some very exciting topics, but we want more! The Summer Issue has 8 authors and is nearly 150 pages. We are looking to double the number of authors, doubling the number of pages is going to be a stretch 😀.

Note:
In case this was not clear, I stated it so in this most recent post at BPO:
If you ever wanted to be a published Perl author, here is your chance - the Science Perl Journal issues have their own ISBNs, papers will be getting their own DOIs, and all contributors are listed as co-authors of the Issue in which they appear.
You may reach out to us on #science on irc . perl . org or on Dr. Adam Russell's very active and awesome, Perl Applications & Algorithms discord server.

Hello. I have the following program.
#!/usr/bin/perl sub print_user_input { my $input = <STDIN>; print $input; } sub mock_user_input { local *STDIN; open STDIN, '<', \"this is fake user input\n"; print_user_input(); } mock_user_input(); __END__ $ perl ./scratch.pl this is fake user input I have successfully used the pattern displayed in the
mock_user_input subroutine to test some user interfacing code I have. However I cannot wrap my head around how this actually works. What exactly does *STDIN mean and why does it need to be localized? Why are we passing a string reference as the third argument to open here? A detailed explanation of this code would be helpful for me. Thanks in advance. submitted by /u/nicholas_hubbard

Guys, Perl is famous for backwards compatibility. What is the oldest bit of perl use that is still relevant that you have heard of?

I would like to know whether function which takes complex data structure of N depth, performs ANY changes on it. Should I Dumper() before and after, use tied hashes/arrays, or some other clever technique?
