Bart Wiegmans writes brrt to the future, a personal blog at brrt-to-the-future.blogspot.com about programming and systems. Since 2018, 8 different Hacker News readers have linked it 13 times, most often “Something about IR Optimization”. The last post was in 2023, but the archive is still widely read.
Too few sampled comments (5) to say how often HN recommends it.?
Why HN links it
Commenters link Bart Wiegmans' posts on the history of the JIT in MoarVM for Perl 6, a joke about layers of indirection explaining Perl 6's speed, and linear scan register allocation on SSA.
Summarised by Claude from a sample of 5 HN comments that link here. Each comment is marked recommending, critical or neutral (citing without judging); how this works.

What Hacker News says?
These are all good questions, and not so easy to answer :-) Any answers I can give are personal, of course, and may well have no relevance to your situation. a): 'Studying' is definitely very important to get an idea of the context of the thing you are trying to solve. (I did a lot of reading both before and during the project). But, it doesn't always relate easily to the problem you have right now. (E.g. I'm using…

HN discussionQuoting the blog post this HN article is supposed to be about[1]: PS: You might read this and be reasonably surprised that Rakudo Perl 6 is not, after all this, very fast yet. I have a - not entirely serious - explanation for that: All problems in computer science can be solved with a layer of indirection. Many layers of indirection make programs slow. Perl 6 solves many computer science problems for you ;-) In the…

HN discussionOh man, block-argument-SSA makes so much more sense to me than Φ-SSA. That alone is going to change my life. Thank you, Max! A lot of this process is the same as graph-coloring register allocation on SSA, of which I found an extensive explanation in Appel's textbook. I think it's maybe time for me to go back to it and do the exercises so I really understand it. The book unfortunately predates the linear allocator ag…

HN discussionThere is a perfectly reasonable (and slightly less than serious) explanation from brrt. https://brrt-to-the-future.blogspot.com/2018/07/perl-6-on-mo... 1. All problems in computer science can be solved with a layer of indirection. 2. Many layers of indirection make programs slow. 3. Perl 6 solves many computer science problems for you ;-)

HN discussionOf course. (For some people.) Here are some videos to give a flavor of the last few years of Perl 6 as it graduated from alpha in 2014 to beta in 2015 to the first ready for production releases of the Rakudo compiler in 2016, to outsiders doing videos about it in 2019 (last video). * 2014. "There's this question of belief". 30 seconds. Charming point made by Perl creator Larry Wall (during a long talk). https://www.…
