A short overview of the places where I hosted different Perl, Perl 6, and Raku events in the past years. The photos below are all made in August 2020.

Welcome to the next issues if The Pearls of Raku! Today, some interesting findings that I discovered while reviewing the previous weeks of The Perl Weekly Challenge and today when I added a new graph to The Coronavirus Observer.

In this article, my review of the Raku solutions to the Weekly Challenge 70. The tasks are: 1) Character swapping, and 2) Generating Gray code. As a regular part of the review, there are two video covering all solutions that were sent by the participants.

My review of the solutions in the Raku programming language of the tasks from Week 67 of the Weekly Challenge. The task 1 is to generate numeric combinations. The task 2 is to work with the letters on a phone keypad.

How do tr, TR string replacements work in Raku. What is a StrDistance type? What happens when you print such objects with ‘put’ and ‘say’?

The Pearls of Raku for your pleasure! The “with” statement, and setting a topic when working with regexes. Also a video with a full review of the Raku solutions 069-2.

Let me demonstrate a few interesting things that I found by looking at the Raku solutions of last week’s Perl Weekly Challenge 1. All of them are notable as they reflect how differently people think, how unexpectedly they approach the same problems, and how big Raku is. So big that you forget or never meet some of its corners. In this issue: method operatos, $*USAGE, and :skip-empty.

Here is a program in Raku to solve the task 1 of the weekly challenge. An interesting thing here is a reminder of how you swap the two elements of an array.

Let us create a one-liner to generate the sequence of the so-called Gray code in the Raku programming language. This code is essentially a method of binary coding so that for each of the following integer number, you only change a single bit.

In this post, I am writing the solution for the second task in this week’s challenge in both Raku and C++.

The task is to find all so-called strobogrammatic numbers, which are the numbers that look the same if you rotate them upside down.

I have published my new book, ‘A Tour of Python 3’. The book is available on LeanPub in PDF and EPUB and on Amazon for Kindle.
In February 2015, Larry Wall gave a keynote talk at the annual FOSDEM conference in Brussels. That was a talk of historical importance. And that was a talk, whose recording was never published. Fortunately, I have an audio recoding, which I am publishing now on YouTube. This seems to be the only existing recoding today.
