We are happy to announce that CosmoShop supports the German Perl/Raku-Workshop.
CosmoShop is the largest pure Perl based shop system.
Since 1997, we have been implementing sophisticated and individual eCommerce projects in the B2B sector with our specially developed store software. We are the central point of contact for the entire spectrum.
These are some answers to the Week 274, Task 1, of the Perl Weekly Challenge organized by Mohammad S. Anwar.
Spoiler Alert: This weekly challenge deadline is due in a few days from now (on June 23, 2024 at 23:59). This blog post provides some solutions to this challenge. Please don’t read on if you intend to complete the challenge on your own.
You are given a sentence, $sentance.
Write a script to convert the given sentence to Goat Latin, a made up language similar to Pig Latin.
Rules for Goat Latin:
1) If a word begins with a vowel ("a", "e", "i", "o", "u"), append "ma" to the end of the word. 2) If a word begins with consonant i.e. not a vowel, remove first letter and append it to the end then add "ma". 3) Add letter "a" to the end of first word in the sentence, "aa" to the second word, etc etc.
Example 1
All three of us returned.
We only had one issue to discuss, the pressing matter of how to handle lexical unimports, builtin version bundles, the integration with use VERSION, and various related topics.
It’s complicated. We’ve been putting together a longer mail on the subject and that will come out as its own thread soon.
DBD::mysql has long provided the interface to connect to the MySQL database from Perl code. But as old as it is, it was implemented with some critical bugs that cannot simply be corrected without breaking mountains of existing code relying on those bugs. For this same reason, though DBD::MariaDB corrects these bugs, care must be taken when migrating existing code to avoid subtle breakage.
This blog post is far too short to explain Unicode and encodings like UTF-8; for anyone seeking a more solid grasp on the concepts, I recommend a read through The Absolute Minimum Every Software Developer Absolutely, Positively Must Know About Unicode and Character Sets (No Excuses!) by Joel Spolsky.
My next dev article about the important concept of cognitive load of code and how to manage it.

You are given a string, $str.
Write a script to return true if there is at least one b, and no a appears after the first b.
Example 1
Input: $str = "aabb"
Output: true
Example 2
Input: $str = "abab"
Output: false
Example 3
Input: $str = "aaa"
Output: false

Quote of the week: “There are features that make the language slow, but those are the features that make the language.”
The 2023 Dancer Advent Calendar, the Twelve Days of Dancer is up and running! We hope you'll enjoy this year's version - there's a lot of fun and practical gifts to be found there.
Hot on the heels of our earlier gift (Dancer2 1.1.0) come two more plugin releases, Dancer2::Plugin::Cache::CHI and Dancer2::Plugin::Syntax::GetPost.
Enjoy! Let us know what you think. Happy holidays to all! (and now it is time for this Dancer to enjoy a long winter's nap)

I started to also post on dev.to and will post there mostly about topics larger than Perl : psychology of programming, software engineering and alike.

You are given a string, $str and a character $char.

Output: 25
Example 2
Input: $str = "java", $char = "a"
Output: 50
Example 3
Input: $str = "python", $char = "m"
Output: 0

I hope the piece above is the first in a series to convince people to consider the reality before passing judgement. It was inspired by one of our research analysts discovering Perl and awk to simplify their lives when cleaning data.
Season's Greetings, Perl!
I've spent almost all of my time since my [last post here]( https://blogs.perl.org/users/ingy_dot_net/2023/05/perl-toolchain-synergy.html) working on a new programming language, YAMLScript.
It's working now and I've decided a do a [2023 Advent YAMLScript Blog]( https://yamlscript.org/posts/advent-2023/index/) for it. The blog started last Friday and will continue (at least) until December 24th.
I encourage you to follow along. At some point this month YAMLScript modules will become available for CPAN and Raku and many other languages. I also encourage you to try writing an [Advent of Code 2023]( https://adventofcode.com/) solution in YAMLScript, if you are playing along with AoC this year.
All the Best, Ingy döt Net

You are given a string, $str.
Write a script to return the score of the given string.
The score of a string is defined as the sum of the absolute difference between the ASCII values of adjacent characters.

It's an example of the fabulous TiddlyWiki (tiddlywiki.com), so it's about 230,000 bytes.

After trying in vain to get some "auto" syntax highlighting here via the editor, I reached for an old trick I've used in the past. Generating HTML using some external service. After a quick Google search, I found https://tohtml.com/perl/. Given a block of Perl code, it'll generate HTML based syntax highlighting that one may add to their post. For example,

You are given a valid IPv4 address.
Write a script to return the defanged version of the given IP address.
A defanged IP address replaces every period “.” with “[.]".
Example 1
Input: $ip = "1.1.1.1"
Output: "1[.]1[.]1[.]1"
Example 2
Input: $ip = "255.101.1.0"
Output: "255[.]101[.]1[.]0"
This the first time that I hear that an IP address could be "defanged."
