The Weekly Challenge

HEADLINES

Welcome to the Week #317 of The Weekly Challenge.

This week turned out to be a welcome back week.

I’m super happy to see so many team members back to the fold and shared their story.

I would like to mention one name, Ted Leahy, who last contributed in the Week #080. Thanks for the contributions in Perl.

With so much energy, the contributions jumped up compared to last two weeks.

Having said, I’m still waiting for the first week in the year 2025 to cross the magical number of 100+ contributions.

Let us all make that happen soon together.
