HEADLINES


Welcome to the Week #202 of The Weekly Challenge.

Last week, India celebrated Republic Day on 26th January. I have some fond memories from my school days. Singing national anthem and getting sweets. Also watching the republic day parade on TV for hours. Ever since, I moved to England, the attachment is no longer as strong as it used to be. I hope and wish, all those living in India still had fun.

You must have noticed that I don’t merge the pull requests during the weekdays? Please bear with me for the time being. I assure you, every single contributions will be accepted, merged and shared with the team before the deadline.

Generally we talk more about the Perl and Raku contributors as compare to other guest languages. However, I know for a fact the it is not easy to get the job done in so many different languages. One such name is Roger Bell_West consistently sharing solutions in Perl, Raku, JavaScript, Kotlin, Lua, Postscript, Python, Ruby and Rust. Hats off to your efforts. Recently Ali Moradi joined the gang big time.

I also noticed Conor Hoekstra is back in action after a short gap. Welcome back.

Ulrich Rieke is another consistent guest contributors. His choice of languages varies.

How can I miss, Robert DiCicco? Sometimes, I wonder how is it possible to do so many different languages. I find it hard to handle just a handfull. Kudos to all guest contributors.

I would also like to thank everyone for suggesting fun tasks. It is a big help for me.

Today, we are giving away Coupon #25 to Roger Bell_West for the book, Learning Perl Exercises by brian d foy. I will share the details with you in a separate email.

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 2023. 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 2023. 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.
