Rust's iterators optimize nicely—and contain a footgun | nicole@web
I saw a claim recently that in functional programming using "map/filter iterates over the list twice, while the foreach loop iterates only once." The author continued that "Haskell can fuse maps together as an optimization but I don't think you safely fuse arbitrary map/filters? I dunno." There are really two claims here: in functional programming, map/filter will do two iterations there is an opt
74 Evolution of Emacs Lisp STEFAN MONNIER, Université de Montréal, Canada MICHAEL SPERBER, Active Group GmbH, Germany Shepherd: Brent Hailpern, IBM Research, USA While Emacs proponents largely agree that it is the world’s greatest text editor, it is almost as much a Lisp machine disguised as an editor. Indeed, one of its chief appeals is that it is programmable via its own programming language. Em

Making rust as fast as go May 2020 Update: as some keen HN commenters have pointed out, it looks like the rust program is not actually equivalent to the go program. The go program parses the string once, while the rust program parses it repeatedly inside every loop. It’s quite late in Sydney as I write this so I’m not up for a fix right now, but this post is probably Fake News. The perf gains from

Pure UI Control
This month marks 10 years that I’ve been paid to build web user interfaces. And today is the second anniversary of Guillermo Rauch’s essay Pure UI. Those two anniversaries have led me to reflect on the past and future of UI development. The past 10 years has seen major improvements in how cross-discipline teams work together to create interfaces. We are much better at thinking about all the differ
How I Use "AI"
I don't think that "AI" models [a] I hate this word. It's not AI. But I want people who use this word, and also people who hate this word, to find this post. And so I guess I'm stuck with it for marketing, SEO, and clickbait. (by which I mean: large language models) are over-hyped. Yes, it's true that any new technology will attract the grifters. And it is definitely true that many companies like

Clojure's deadly sin
This article is about laziness in Clojure. It is intended to be a comprehensive and objective (however possible) critique of lazy sequences as a feature. In no way do I want this to be a judgment of the decision to make Clojure lazy. Clojure the language is by no means formulaic; creating it involved making a plethora of impactful choices. We can judge by Clojure's longevity that the total package

This essay provides a broad overview of the sub-field of machine learning interpretability. While not exhaustive, my goal is to review conceptual frameworks, existing research, and future directions.

Since last fall, Neven has been doing an internship to develop a new aliasing model for Rust: Tree Borrows. Hang on a second, I hear you say – doesn’t Rust already have an aliasing model? Isn’t there this “Stacked Borrows” that Ralf keeps talking about? Indeed there is, but Stacked Borrows is just one proposal for a possible aliasing model – and it has its problems. The purpose of Tree Borrows is
