The Weekly Challenge

HEADLINES

Welcome to yet another edition of the weekly challenge.

I noticed the Week #125 was not so happening as compare to other weeks.

Could holiday season be the reason? Possibly.

I know some of the Team PWC members are enjoying the holiday break. Having said that they are not skipping the weekly contributions.

It makes me feel guilty as I haven’t contributed in the last 2 weeks. I am too busy in my day job work. I will try to find some time this week.

I am not sure if you have noticed something about the blog contributions by Team PWC?

More and more members come up with catchy blog title now a days. Earlier it was just one or two.

Some of my favourites from last week contributions are as follows:

1. Pythagorean Tree with Raku by Arne Sommer.

2. Triple Tree Rings by Colin Crain.

3. Pythagorean Diameter by Roger Bell_West.

Let us share some interesting stats from the GitHub repository.

1. Commits: 19,233 (+137)

2. Pull Requests: 4,713 (+32)

3. Contributors: 173

4. Fork: 219

5. Stars: 98

Last but not least, I would like to thank each and every member for their support and encouragement.

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 2021. 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 2021. 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.
