Monday morning, and there are new tasks in the new weekly challenge 067. Both of them require similar Raku tools, namely, the cross operator X.

An interesting task offered on Week 54 of the Perl Weekly Challenge: Print the Collatz Conjecture for the given integer number. The conjecture is that for any starting number, the sequence ends with 1.

Task 1: Find the first 20 so-called Gapful numbers. Task 2: Print all palindromic ddmmyyyy dates between 2000 and 3000. Task 3: Find the first multiple of the given number, which only contains digits 0 and 1.

Here’s another drill offered by the Perl Weekly Challenge on Week 44. The task is to get a string 123456789 and insert the signs + and – between the digits so that the evaluated value of the new string equals 100.

A few Raku challenges solutions: printing arrays, generating Leonardo numbers, converting to octals.

A couple of days ago, Perl 7 was announced.
Isn’t that a great news? Well, yes and no. I have my personal feelings about this but I hope I can also see some other things that are not so much subjective.

In the second task of this week’s Challenge, you have to find two integers that being powered as xy, give the requested integer number n.

Hey there, there’s another task #066-1 offered by the Perl Weekly Challenge (why still not mentioning Raku in the name?).
Integer-divide the two given integers, $m and $n, without using multiplication, or division, or modulo.

Here is my Raku solution of the Task 1 on Week 65. The task is to print all $n-digit numbers, whose sum of digits is $s.

Let me demonstrate another interesting one-liner that I find to be a good addition to my last years’s book Raku One-Liners. The task was inspired by this week’s problem from the Perl Weekly Challenge.

In this blog post, I am giving a number of examples of how you can use hashes in the Raku programming language in a correct and incorrect ways and explain how to avoid the chance to mislead yourself.

The answer is: Accessing array or hash items with a proper sigil!

When working on preparing data for the covid.observer site, I discovered a couple of interesting findings, which I did not notice earlier or did not pay much attention to it.

I’ve re-published a bunch of interviews that I took about five years ago: brian d foy Audrey Tang Flávio Glock Damian Conway Stevan Little Carl Mäsak Reini Urban There’s a couple of more, dating even earlier history. Maybe one day they will appear here too 🙂
Before the GitHub 02/02/2020 Archive program, I uploaded all my books published by DeepText to github.com/ash/books. I hope it will be frozen and archived for the future generations :-D.

Some time ago, I published an article about using NativeCall in Raku to call functions written in C. Today, let’s see how you can call simple functions written in C++ or in Fortran.

I’d like to try how Raku can help in building a simple stack-oriented language.
