2019.43 Performance Toaling

Timo Paulssen has published an impressive progress report on his work on the performance tooling of Raku on the MoarVM backend, specifically about the user interface of the Heap Snapshotter. This now allows multiple ways to navigate a MoarVM heap snapshot. This should make doing performance work / debugging a lot more fun!

More video tutorials

Yanzhan Yang just keeps on going! He finished 30 episodes of the Raku Beginner Tutorial. And he published 7 video tutorials about solving Exercism exercises:

And he also started on handling Rosetta Code problems, 4 of them so far:

Way to go!

  • Jan-Olof Hendig fixed an issue in the reporting of UTF-8 encoding errors.
  • Christian Bartolomäus fixed a copy-pasto in a debug message for the initial timer thread.

  • And many smaller fixes and improvements.

Winding down

In the past week many people were working on the final tweaks to get the 2019.10 Rakudo Compiler Release out of the door. Alas, it is not yet done, so expect a report about that in the next Rakudo Weekly, the weekly blog about the Raku Programming Language on Rakudo. See you then!
