Making a Super Cal if Rage Will Stick Ex Paella Down Us

https://blogs.perl.org/users/saif/2024/05/making-a-super-cal-if-rage-will-stick-ex-paella-down-us.html

On this site: https://codegolf.stackexchange.com/questions/246845/convert-json-object-of-directories-to-list-of-paths

There is an interesting perl solution but I'm trying to wrap my head around it and am baffled.

map/}/?/{/&&say($s)..$s=~s|[^/]+/$||:($s.=s/"//gr."/"),/{?}|".+?"/g When I do a simple test: my $s = <some json string> .. the map above I don't get any output. Thanks in advance 

Convert JSON object of directories to list of paths

Task The input consists of a JSON object, where every value is an object (eventually empty), representing a directory structure. The output must be a list of the corresponding root-to-leaf paths.

I have a bunch of files that I am parsing out a simple tag
<institution content-type="division">(.+?)?<\/institution>

Everything is going fine until I hit this result:
2) School of Chemical & Biomolecular Engineering

This is complaining because it thinks the ) is unmatched. How do I get it to accept whatever is in the capture? I tried playing around with \Q and \E but that isn't working. For clarity, I won't know what is in this tag, it could be anything at all and the tag is simple enough that I don't want to use some XML parser.

This Week in PSC (147)

https://blogs.perl.org/users/psc/2024/05/this-week-in-psc-147.html

I'm experimenting with different frameworks and I've come across this wonderful catalyst framework based on Perl, does anyone know of a front end (which is website, forums, etc.) coupled with a back end (tracker engine) for use with modern Perl? I have a PHP based one and was wondering if it was possible to do the same using Perl.

Perl Weekly Challenge 268: Magic Numbers

https://blogs.perl.org/users/laurent_r/2024/05/perl-weekly-challenge-268-magic-numbers.html

Asking for a friend. No really, I don't use VSCode but I know that a lot of people do and in one week I had two different people ask me this. I didn't see anything in the Visual Studio Marketplace. I'm looking for something like markdown-preview enhanced, but for Pod.

If you don't have that, is it something that you would want?

If it's something you want, would you throw in some money to have it? This isn't something I'd do myself, but I know some people with some free time who could use a little money. I could crowdfund it or whatever. The intent is to have something free in the Marketplace.

Would you care if it's not implemented in Perl? If it was JS or whatever VSCode prefers but does the job, that's fine with me (and remember I don't use VSCode). I have no idea how much that matters, but I'd hate for people to have to do all sorts of crazy setup, which for many people is installing anything from CPAN.

How to install CRISPRCasFinder (for detection of CRISPRs and cas genes)

https://blogs.perl.org/users/glycine/2024/05/how-to-install-crisprcasfinder-for-detection-of-crisprs-and-cas-genes.html

I need to find the distance between two GPS coordinates. Geo::Calc does this effectively, but it hasn't been updated in over a decade, and, more seriously, it adds a significant startup delay just by loading the module:

root@1c8fb16bd7bb:/app# time perl -e 'use v5.38' real 0m0.005s user 0m0.001s sys 0m0.004s root@1c8fb16bd7bb:/app# time perl -e 'use v5.38; use Geo::Calc' real 0m0.679s user 0m0.631s sys 0m0.048s

The portions of B::Generate associated with PADOP construction use static variables, and thus are not thread safe.

This release imports that section of Generate.xs into sealed.xs and removes the static variable dependencies.

The Perl Toolchain Summit 2024

https://blogs.perl.org/users/paul_johnson/2024/05/the-perl-toolchain-summit-2024.html

I am hopeful someone has done this before as I'm stuck... I have a 3TB disk image file and I am trying to find all the different email addresses that I've used over the past 22 years.

I can use hex editor tools to find them but it takes days to look at the data and pick out even a handful of matches.

I use Perl regularly but I normally scan text files and do non binary file actions. That's easy since I can do a line by line search. But binary seems different.

If I want to search for zeropoint@ (no domain because I've used dozens of ISPs over the years and that's why I am trying to figure this out.) inside the entire 3TB file, what's the best way to do that? I can dump the results to a file and then clean it up but the search part has me stuck

Thank you
