Goならわかるシステムプログラミング第2版が出たので書評しますね - moriyoshiの日記
少し前になりますが、3月23日に、渋川よしきさんの著された「Goならわかるシステムプログラミング 第2版 」が発売されました。初版と比べてかなり加筆されておりパワーアップしているので、初版をすでにお持ちの方でもさらに興味深く読むことのできる内容に仕上がっている、というのが第一印象です。 残念ながら初版発売時に記事にする機会がなかったのですが、あらためて今回書評したいなと思いましたので、徒然書いていきたいと思います。 この本は実はシステムプログラミングの本ではないかもしれない 「システムプログラミング」とは何でしょう。正直私にもわかりません。その語をはじめに思い浮かべた人は、プログラミングという概念のその中にあえて「システムプログラミング」という分類を作ろうと思い至ったということですから、きっと「非システムプログラミング」というものもあるということでしょう。知らんけど。しかし、これは本書の位
REST API Design Best Practices Handbook – How to Build a REST API with JavaScript, Node.js, and Express.js
By Jean-Marc Möckel I've created and consumed many API's over the past few years. During that time, I've come across good and bad practices and have experienced nasty situations when consuming and building API's. But there also have been great moments. There are helpful articles online which present many best practices, but many of them lack some practicality in my opinion. Knowing the theory with

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

Wasm core dumps and debugging Rust in Cloudflare Workers2023-08-14 A clear sign of maturing for any new programming language or environment is how easy and efficient debugging them is. Programming, like any other complex task, involves various challenges and potential pitfalls. Logic errors, off-by-ones, null pointer dereferences, and memory leaks are some examples of things that can make software
The diagram above is the compiler for the language Bolt we’ll be building. What do all the stages mean? I have to learn OCaml and C++? Wait I haven’t even heard of OCaml… Don’t worry. When I started this project 6 months ago, I had never built a compiler, nor had I used OCaml or C++ in any serious project. I’ll explain everything in due course. In this series of posts we’ll be building a proper pr
A new JavaScript backend was merged into GHC on November 30th, 2022! This means that the next release of GHC will be able to emit code that runs in web browsers without requiring any extra tools, enabling Haskell for both front-end and back-end web applications. In this post, we, the GHC DevX team at IOG, describe the challenges we faced bringing GHCJS to GHC, how we overcame those challenges, and
The Go Programming Language and Environment – Communications of the ACM
Go is a programming language created at Google in late 2007 and released as open source in November 2009. Since then, it has operated as a public project, with contributions from thousands of individuals and dozens of companies. Go has become a popular language for building cloud infrastructure: Docker, a Linux container manager, and Kubernetes, a container deployment system, are core cloud techno

Where Programming, Ops, AI, and the Cloud are Headed in 2021
In this report, we look at the data generated by the O’Reilly online learning platform to discern trends in the technology industry—trends technology leaders need to follow. But what are “trends”? All too often, trends degenerate into horse races over languages and platforms. Look at all the angst heating up social media when TIOBE or RedMonk releases their reports on language rankings.

Functors and Monads For People Who Have Read Too Many "Tutorials" - iRi
Celebrating Over 10 Years Of Being Too Lazy To Pick A Tagline Title is literally true. This may not be the best place to learn about these concepts for the first time, because I'm going to focus on knocking down the misconceptions about them. Then again, it may not be the worst place, for the same reason. I had promised myself I would not add to the pile of functor or monad "tutorials", but I've b
This past May, I started a new job working in Rust. I was somewhat skeptical of Rust for a while, but it turns out, it really is all it’s cracked up to be. As a long-time C++ programmer, and C++ instructor, I am convinced that Rust is better than C++ in all of C++’s application space, that for any new programming project where C++ would make sense as the programming language, Rust would make more
This article is a translation, the original version is available here. I started using the OCaml language regularly around 2012, and since then, my interest and enthusiasm for this language have only grown. It has become my preferred choice for almost all my personal projects, and it has also influenced my professional choices. Since 2014, I have been actively participating in public conferences d
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

Art for ReScript Blog, credit to Bettina SteinbrecherThis is not evangelism of ReScript or a one-to-one comparison with TypeScript. I love TypeScript. I decided to rewrite a small TypeScript+React+Jest side project into ReScript. ReScript is not new. In a way it’s as old as JavaScript itself. ReScript is a rebranding of ReasonML (Facebook) and BuckleScript (Bloomberg), which wrap OCaml on both end
Common Lisp VS Racket. Feedback from (common) lispers.
Common Lisp VS Racket - testimonies.md Developer experience, libraries, performance… (2021/11) I'll preface this with three things. 1. I prefer schemes over Common Lisps, and I prefer Racket of the Schemes. 2. There is more to it than the points I raise here. 3. I assume you have no previous experience with Lisp, and don't have a preference for Schemes over Common Lisp. With all that out of the wa
Technology Trends for 2024
This has been a strange year. While we like to talk about how fast technology moves, internet time, and all that, in reality the last major new idea in software architecture was microservices, which dates to roughly 2015. Before that, cloud computing itself took off in roughly 2010 (AWS was founded in 2006); and Agile goes back to 2000 (the Agile Manifesto dates back to 2001, Extreme Programming t
A professional programmer delivers value through the authoring and maintaining of software that solves problems. (There are other important ways for professional programmers to deliver value but this post is about programming.) Programmers rely on various tools to author software. Arguably the most important and consequential choice of tool is the programming language. In this post, I will articul
At my first few programming jobs I worked on Java projects. It is here that I first learned to appreciate, but also hate strict typing. In a short amount of time I was drawn to front-end work and became proficient in JavaScript and really fell in love with the language. It was relatively easy to master, which enabled me to focus more on the user and quality and to work much faster than with Java.

K-nearest neighbors (k-NN) is a Machine Learning algorithm for supervised machine learning type. It is used for both regression and classification tasks. As we already know, a supervised machine learning algorithm depends on labeled input data, which the algorithm learns to produce accurate outputs when input unlabeled data. k-NN aims to predict the test data set by calculating the distance betwee
Language Pragmatics Engineering
Summary: The code that gets written is the code that’s easier to write. Anything not forbidden by the language semantics will be done as a “temporary fix”. Codebases decay along the gradient of expedient hacks. Programming languages have syntax, semantics, and pragmatics: how the language is used in practice. The latter is harder to design for. Language pragmatics is tooling, best practices, and t

Sketch of a Post-ORM
I’ve been writing a lot of database access code as of late. It’s frustrating that in 2023, my choices are still to either write all of the boilerplate by hand, or hand all database access over to some inscrutable “agile” ORM that will become a crippling liability in the 2-3y timescale. This post is about how I want to use databases, from the perspective of an application server developer—not a DBA
