Andrew Shitov is asking for the community’s opinion on whether or not to have an in-person Raku Conference in Riga in 2022 in The Raku Conference Update. Cancelling an in-person event now, means no financial risk, which seems safest.
FOSDEM 2022 Status
Being a serial organizer, Andrew Shitov also published the schedule for the Raku DevRoom at FOSDEM 2022 on Saturday 5 February (times in UTC, add one hour for CET):
- 9:00 Intro by Andrew Shitov.
- 9:05 “Keeping the Past to preserve the Future” by Elizabeth Mattijsen.
- 9:40 “Free Software, Dependency Management, and what I got wrong at FOSDEM 21” by Daniel Sockwell.
- 10:25 “Multi-language Data Wrangling and Acquisition Conversational Agents” by Anton Antonov.
- 11:25 “Class learning analytics” with Raku by JJ Merelo.
- 11:50 “From Unix shell (*sh) scripting to Raku” by Marc Chantreux.
- 12:50 “Decentralized Authentication” by Konstantin Narkhov.
- 13:30 “A Raku Grammar for Navigation Lights” by Steve Roe.
- 14:15 “Radically simple testing in Raku” by Daniel Sockwell.
- 14:45 “GitHub Actions (in|for) Raku” by JJ Merelo.
- 15:35 “Raku Steering Council Q&A Panel” by Andrew Shitov and the Raku Steering Council.
A full program indeed. Looking forward to it already!
Anton Antonov has started a new blog about data wrangling, with the motto:
One of my current life missions is the speeding up of the next AI winter coming. I have decided to use Raku to accomplish that mission.
And as a first post: Introduction to Data Wrangling with Raku.
Wim Vanderbauwhede has written a blog post about the need for low-carbon and sustainable computing, and what developers can do about it: Frugal computing: developer perspective. Not strictly Raku related, but important nonetheless (/r/rakulang comments).
Testing with Github Actions
JJ Merelo has written a short how-to do testing with Github Actions in: Testing your Raku Module using Github Actions.
Weekly Challenge #148 is available for your perusal.
New Pull Requests
- Update information about methods for distributing modules
update-submodules.plshould handle linked worktrees created by git-worktree
- Remove the fixed size allocator (FSA)
- Fix handling of native unsigned integers (MoarVM)
- Fix handling of unsigned native integers (NQP)
NYIas a sub
- Specify base of non base 10 invalid numbers
- Implement smartmatch as a dispatcher
- implement sub
- Daniel Green‘s work of the past weeks on using
mimallocfor memory allocation in MoarVM, was merged. This resulted in a 10% faster spectest (looks like caused by faster parsing and quicker startup).
- Nicholas Clark made sure that allocations of MVM registers are 8-byte aligned (needed for some pesky processor types, and probably good for processing speed in general). They also marked many functions in MoarVM as
staticfor better optimizability.
- Stéphane Payrard added a Github Action to check links in markdown files in NQP.
- Stefan Seifert implemented several of the unsigned native int ops in NQP on the MoarVM as well as the JVM backend.
- Elizabeth Mattijsen made accessing positional captures (
$1, …) about 5x as fast, Rat to FatRat coercion (and vice-versa) about 5x as fast, array slices without adverbs about 2.5x as fast, and an unsuccessful call to
.firstabout 40% faster.
- Vadim Belman fixed an issue if an
Enumwas created with one of the values having the same name as a core class.
- And many smaller tweaks and fixes.
