The Weekly Challenge

HEADLINES

Welcome to Week #181 of the weekly challenge.

Welcome a new member, Bejoy Mathews, an experienced Perl hacker. Thanks for the first contributions in Perl.

Today, we are giving away Token #4 to Kueppo Wesley for the book, Learning Perl Exercises by brian d foy. I will share the details with you in a separate email.

Another announcement of the week, since today is the first Monday of the month and time to declare the next champion, Stephen G. Lynn. He joined the Team PWC in the Week #168. Ever since he has contributed in both Perl and Raku without missing a week. He even shared blog post every week except the first two weeks.

Welcome back, Tyler Wardhaugh, after the break and thanks for introducing a new language, Fennel to the Team PWC. With this new addition, we now have 91 guest languages other than Perl and Raku. It would be big deal when we get to the magic number of 100.

Laurent Rosenfeld is back with maximum guest contributions, 23 solutions in 14 languages.

We had surprise element last week too as Ali Moradi contributed 14 solutions in 7 languages alongwith the regular contributions by Roger Bell_West.

I would also like to mention another member, AhmetEmre, for guest contributions. Last week, he shared solutions in BQN for the Week 1-56 as well as current week. With this, he jumped to rank #12 in the Guest Leader board.

I am back again after a short break and shared solutions in Perl, Raku, Python, Java and Swift .

Our solo sponsor Pete Sergeant has been a great support to keep us motivated. We are lucky that he agreed to continue the journey with us in the year 2022. I would like to personally thank Pete and his entire team for their generosity. It would be great if we could add few more to sponsor the prize money so that we could go back and declare weekly champions as we have done in the past. I hope and wish this will become possible in 2022. The amount doesn’t have to be huge. However, it would be nice to show off bunch of supporters. If an organisation comes forward and supports us then that would be the ultimate achievement.

    still a bit of uncertainty in the equation, but the basics

    coming and it wasn't going to be pretty.
