Yours truly is on the road to the 22nd German Perl/Raku Workshop 2020 in Erlangen, Germany. The program starts on Tuesday evening with a Pre-event Social. The program has the following presentations with Raku content:

• Eine Strategie für Perl und Raku by Herbert Breunung.
• Sets and Bags, and how NOT to use them by Elizabeth Mattijsen.
• Cro HTTP router essentials by Jonathan Worthington.
• Raku rules and grammar tutorial by Jonathan Worthington.
• Realizing Raku macros by Jonathan Worthington.
• Querying the Ethereum blockchain nodes with Raku by Konstantin Narkhov.
• Data Science mit Perl und Raku by Sören Laird Sörries

Another release

A problem in an upstream library used by MoarVM, made it impossible to build the 2020.02 Rakudo compiler release on Alpine GNU/Linux. The problem has been fixed in the upstream library, and a new release has been made by Alexander Kiryuhin. (Twitter, Linux packages by Claudio Ramirez).

Run and Shell on Windows

About a year ago Patrick Böker started an issue on how Proc::Async should call cmd.exe on Windows. Due to recent questions, this got a lot of new comments in the past week. If you have any feelings about the subject, please join in (/r/programming comments)!
