The end of classical computer science is coming, and most of us are dinosaurs waiting for the meteor to hit. I came of age in the 1980s, programming personal computers such as the Commodore VIC-20 and Apple ][e at home. Going on to study computer science (CS) in college and ultimately getting a Ph.D. at Berkeley, the bulk of my professional training was rooted in what I will call “classical” CS: p

In an interview with Evrone, Ryan Dahl speaks about the main challenges in Deno, the future of JavaScript and TypeScript, and tells how he would have changed his approach to Node.js if he could travel back in time. We met with Ryan Dahl, the creator of Node.js, to discuss the origins of the platform, its impact on JavaScript, and his thoughts on its future. In the interview he also reflected on hi
Rewriting the Ruby parser
At Shopify, we have spent the last year writing a new Ruby parser, which we’ve called YARP (Yet Another Ruby Parser). As of the date of this post, YARP can parse a semantically equivalent syntax tree to Ruby 3.3 on every Ruby file in Shopify’s main codebase, GitHub’s main codebase, CRuby, and the 100 most popular gems downloaded from rubygems.org. We recently got approval to merge this work into C

Preparing for the Systems Design and Coding Interview
At Big Tech and high-growth startups, coding and systems design interviews are common - and fairly standard. A lot of people have asked me for preparation advice for these. Here is what I used when getting ready for an E5/E6 Facebook interview, and the one at Uber - where I was hired as a senior software engineer (L5). It's the same resources I recommend to people who are preparing for Big Tech or
12.6. B-Trees — CS3 Data Structures & Algorithms
12.6. B-Trees¶ 12.6.1. B-Trees¶ This module presents the B-tree. B-trees are usually attributed to R. Bayer and E. McCreight who described the B-tree in a 1972 paper. By 1979, B-trees had replaced virtually all large-file access methods other than hashing. B-trees, or some variant of B-trees, are the standard file organization for applications requiring insertion, deletion, and key range searches.
Over the course of my Spring 2020 semester at Harvey Mudd College, I developed a self-hosting compiler entirely from scratch. This article walks through many interesting parts of the project. It’s laid out so you can just read from beginning to end, but if you’re more interested in a particular topic, feel free to jump there. Or, take a look at the project on GitHub.

CRDTs go brrr
5000x faster CRDTs: An Adventure in Optimization July 31 2021 A few years ago I was really bothered by an academic paper. Some researchers in France put together a comparison showing lots of ways you could implement realtime collaborative editing (like Google Docs). They implemented lots of algorithms - CRDTs and OT algorithms and stuff. And they benchmarked them all to see how they perform. (Cool
Since I was unable to travel for a couple of years during the pandemic, I decided to take my new-found time and really lean into Rust. After writing over 100k lines of Rust code, I think I am starting to get a feel for the language and like every cranky engineer I have developed opinions and because this is the Internet I’m going to share them. The reason I learned Rust was to flesh out parts of t

文系学部卒でも無条件で不合格にならないアメリカのオンラインコンピューターサイエンス修士コースを調べ、出願校を決めた｜Toshinori Sugita
出願校最初の出願校は、ジョージア工科大学のOMSCSになりそうだ。履修できる授業の種類、オンラインコースの懐の深さ（合格率の高さ）（、費用）が主な理由だ。 前回の記事を書いた時点では、ペンシルバニア大学のMCITがベストではないかと考えていた。 しかし、他の選択肢を十分検討していなかったので、候補になり得るコースをリストアップして比較した。特に気にしたのは、つぎの点だ。 ・文系学士が無条件でNGにならない ・CS推奨であっても、テストやMOOCs受講、業務経験などでなんとかなる ・アメリカ（最初の候補として。イギリスやオーストラリアがダメというわけでは全然ないが、英語で学ぶことを前提としたい） ・授業（基礎、分散システム、その他機械学習、データサイエンスなど共通理解になり得るものが選択できる） ・出願要件の具体的な数字（英語テスト、書類、出願期限） ・合格率（オンラインはオンキャンパスと比
Statically typed programming languages can help catch mismatches between the kinds of values a program is intended to manipulate, and the values it actually manipulates. While there have been many bytes spent on discussions of whether this is worth the effort, some programming language designers believe that the type checking in current languages does not go far enough.

Last year I finally decided to learn some Rust. The official book by Steve Klabnik and Carol Nichols is excellent, but even after reading it and working on some small code exercises, I felt that I needed more to really understand the language. I wanted to work on a small project to get some hands-on experience, but most of my ideas didn’t feel very well suited for Rust. Then I started reading the
I’m a fairly frequent Hacker News lurker, especially when I have some other important task that I’m avoiding.

Functors and Monads For People Who Have Read Too Many "Tutorials" - iRi

Exactly ten years ago today, we published "Why We Created Julia", introducing the Julia project to the world. At this point, we have moved well past the ambitious goals set out in the original blog post. Julia is now used by hundreds of thousands of people. It is taught at hundreds of universities and entire companies are being formed that build their software stacks on Julia. From personalized me
It is now 45+ years since C++ was first conceived. As planned, it evolved to meet challenges, but many developers use C++ as if it was still the previous millennium. This is suboptimal from the perspective of ease of expressing ideas, performance, reliability, and maintainability. Here, I present the key concepts on which performant, type safe, and flexible C++ software can be built: resource mana

The Alkyne GC · mcyoung
Alkyne is a scripting language I built a couple of years ago for generating configuration blobs. Its interpreter is a naive AST walker1 that uses ARC2 for memory management, so it’s pretty slow, and I’ve been gradually writing a new evaluation engine for it. This post isn’t about Alkyne itself, that’s for another day. For now, I’d like to write down some notes for the GC I wrote3 for it, and more
