The Graphics::Toolkit::Color 2.0 feature overview post provides an impressive look at all of the most significant improvements that have been made in developing GTC 2.0. The description outlines how GTC has grown beyond only doing basic coloring routines to include now a much richer, more complex, multi-space colored library complete with the ability to create beautiful gradients, accurately measure colors for perceptual purposes, and a variety of tools for use by both designers and developers. Overall, this is a succinct overview that does an excellent job of showcasing the reasons why GTC 2.0 is a unique addition to CPAN.

by Flávio Glock (FGLOCK)

This is a great update regarding the addition of native CPAN support to Perl-on-JVM tooling. The example uses the ability to use an already developed CPAN client for installing modules and accessing the overall CPAN ecosystem in a more natural way than would be done with the non-JVM versions of the clients. It gives many real-world examples and is an excellent source of information for those who want to connect Perl and Java.

Enjoy a quick recap of last week's contributions by Team PWC dealing with the "Count Prefixes" and "Valid Times" tasks in Perl and Raku. You will find plenty of solutions to keep you busy.

by Arne Sommer

Raku Musings has a clearly written "Count the Times" post that gives a well-organised overview. It shows how idiomatic features work together effectively in Raku, resulting in a clear and elegant solution. There is an excellent balance between compact code and an informative explanation. The post demonstrates the use of expressive constructs that lend themselves to solving this type of problem using Raku.

by Bob Lied

Bob Lied writes an engaging post about a problem in a clear manner, interspersing logic with humor; making it a pleasure to read! The author reviews alternative methods and their advantages/disadvantages and demonstrates a practical approach as well as demonstrating good Perl coding skill.

by Bob Lied

Bob Lied's "Valid Times" post systematically breaks down the issue into distinct steps while also providing significant attention to detail in regards to possible edge cases and practical limitations of validation of times. It presents a succinct but complete Perl code and corresponds with sound logic behind the choice of this Perl implementation, which allows readers to follow along easily and use as a reference when addressing the same type of parsing problems.

by Jaldhar H. Vyas

The Jaldhar's blog has written an extensive, interesting post detailing how to perform Week 366 tasks. It does so by separating them into two sections: Problem 1 and Problem 2. This helps readers easily understand the problems themselves, as well as providing a clear path to solution using Perl. The blog also clearly states the logic behind each step, allowing readers to learn from the blogs experience while still being able to easily move on to solving this week's challenges independently.

by Jorg Sommrey

The blog post written for the week of 366 by Jörg, presents an elegant solution that exemplifies the use of clear and concise Perl programming techniques with a command of idiomatic constructs. The reader will appreciate Sommrey's clean, logical approach in solving the problem space and his appreciation for the use of expressive and efficient code, which reflects both familiarity and appreciation for the inherent beauty of programming.

by Luca Ferrari

Luca Ferrari's post is a further example of his continuing theme of approaching Perl Weekly Challenge in an analytical as well as exploratory way; frequently developing solutions in several languages and platforms to help him better understand the challenges. Luca's posts provide very useful instruction/examples; help you learn through experimentation/experience; and help you to truly think about and re-examine/consider the real-world nature of the solution.

by W Luis Mochan

The write-up gives a very reasoned overview of the problem with easy-to-follow methods of solving it using logical thinking. There is a good amount of coding as well as thorough explanations that create a valid and helpful source for those searching for an understanding of this issue and its methods of resolution using Perl.

by Matthias Muth

The article from Matthias Muth, entitled Matthias Muth's Week 366, is a clear and precise description of his thought processes relating to solutions presented in a concise manner while also being well-organised so as to make it easy to understand the underlying concept. It has an elegant and idiomatic style similar to that of Matthias' other contributions to the Perl Weekly Challenge, and it has a very clean decomposition of the problem that allows more experienced readers to develop an appreciation for it.

by Packy Anderson (PACKY)
