How to review code effectively: A GitHub staff engineer’s philosophy
As a staff engineer at GitHub, code review is one of my main focus areas in my day to day work. Over the past eight years, I’ve reviewed more than 7,000 pull requests. Why so many? Because code review is crucial to building good software and another set of eyes can often spot issues you would have otherwise missed. I see code review as one of the most important aspects of my job. In fact, whenever
Linux Hardening Guide | Madaidan's Insecurities
Last edited: March 19th, 2022 Linux is not a secure operating system. However, there are steps you can take to improve it. This guide aims to explain how to harden Linux as much as possible for security and privacy. This guide attempts to be distribution-agnostic and is not tied to any specific one.

In this post I will hopefully detail my entire home network. Some of this has been in separate posts explaining single items, but nowhere do I have all of the network in one post with all the changes since last year. Here is a full shot of the rack in my house. Its in a centrally located closet which happens to have a 2ft x 2ft chase into the attic, which is very handy for running network cables.
Making JavaScript run fast on WebAssembly - Bytecode Alliance
JavaScript in the browser runs many times faster than it did two decades ago. And that happened because the browser vendors spent that time working on intensive performance optimizations. Today, we’re starting work on optimizing JavaScript performance for entirely different environments, where different rules apply. And this is possible because of WebAssembly. We should be clear here—if you’re run
How to Write Good Documentation (And Its Essential Elements)
This post highlights some of the key components of good documentation, and goes through some of the steps you could take to improve the way you document your code. Documentation is one of the most important and under-rated aspects of any library or open-source project. If you are writing code that will be used by someone other than yourself, it needs to be documented. Period. After using many libr
With ChatGPT being all the rage today, Apple users are likely wondering how to access it on their iPhones. For those of you who aren't aware, ChatGPT is an AI-powered chatbot that allows you to have human-like conversations. Although ChatGPT doesn't have an official mobile app, you can access its capabilities on your iPhone via Siri. So, if you're already interested, read on as we'll teach you how
There are many articles written about React performance optimizations. In general, if some state update is slow, you need to: Verify you’re running a production build. (Development builds are intentionally slower, in extreme cases even by an order of magnitude.) Verify that you didn’t put the state higher in the tree than necessary. (For example, putting input state in a centralized store might no
Code improves with multiple reviews and revisions, and this process isn’t something that can be done alone. Spotting errors in code design is difficult at the best of times — and the closer you are to the work, the harder it can be to critique. That’s where code reviews come in. The beginning: introducing code reviewsWhat is a code review? Code improves with multiple reviews and revisions, and thi
暗から明へーアマンダ・ゴーマン氏が米大統領就任式で朗読した詩の内容は？翻訳者の読み解き（鴻巣友季子） - エキスパート - Yahoo!ニュース
第46代アメリカ大統領にジョー・バイデン氏、副大統領にカマラ・ハリス氏が就任した。就任式で、二十二歳の青年桂冠詩人アマンダ・ゴーマン氏が自作の詩The Hill We Climb（わたしたちの登る丘）を朗読し感動を呼んだ。 就任式に詩人が自作の詩を朗誦するのは、一九六一年のジョン・F・ケネディ大統領就任式以来の慣わし。この時にはロバート・フロスト氏がその任につき、The Gift Outrightを詠唱した。クリントン氏の第一期大統領就任時には、黒人女性詩人のマヤ・アンジェロウ氏が招ばれ、On the Pulse of Morningを捧げた。 今回のアマンダ・ゴーマン氏の二十二歳というのは歴代最年少になるという。彼女はどんな詩を読んだのだろうか？ 無数の読みを喚起する暗示や比喩や引用に満ちた詩であり、専門家による読み解きはたくさんあるだろうから、本稿では翻訳者として気になった点を見ていき
Cloud compute is usually seen as an ethereal resource. You launch VMs and spin them down, billed to the second. The billing and the mental model make it seem like these resources are limitless. That's typically one of the selling points versus on-prem compute. They can scale responsively to your load so you're not paying for excess compute that you don't need but it's there when you want it. Of co
こんにちは。SRE の @chaspy です。 ユーザに価値が提供できなくなってしまうシステム障害は起きてほしくはありませんが、絶対に発生しないとは言い切れません。 そんなシステム障害は、そもそも発生頻度が不定、かつ多くないので、どのように対応すべきかを体系化することは（起きる事象が毎回異なることも相まって）難しいと思います。 本記事では、Quipper において、どのように障害対応を行うのか、また、障害発生時の考え方を紹介します。 障害はどのように対処されていくのか 障害発生フロー Quipper では 標準化された障害時連絡のフロー / 障害レベルがあります。 これによって、障害の内容、影響範囲によっては親会社のリクルートマーケティングパートナーズへのエスカレーションが必要であることと、その基準が言語化されました。また、エスカレーション時に送るメールのテンプレートも用意されており、「誰

(There is good discussion on this article on Hacker News and Reddit) Reddit is currently the most popular search engine. The only people who don’t know that are the team at Reddit, who can’t be bothered to build a decent search interface.

Now that our platforms are up and running as usual after yesterday’s outage, I thought it would be worth sharing a little more detail on what happened and why — and most importantly, how we’re learning from it.

Rails design patterns
A design pattern is a repeatable solution to solve common problems in a software design. When building apps with the Ruby on Rails framework, you will often face such issues, especially when working on big legacy applications where the architecture does not follow good software design principles. This article is a high-level overview of design patterns that are commonly used in Ruby on Rails appli

One of the most impactful things we’ve worked on in TypeScript 5.0 isn’t a feature, a bug fix, or a data structure optimization. Instead, it’s an infrastructure change. In TypeScript 5.0, we restructured our entire codebase to use ECMAScript modules, and switched to a newer emit target. What to Know Now, before we dive in, we want to set expectations. It’s good to know what this does and doesn’t m

They are popular and they are misunderstood. Containers have become the default way applications are packaged and run on servers, initially popularized by Docker. Now, Docker itself is misunderstood. It is the name of a company and a command (a suite of commands, rather) that allow you to manage containers (create, run, delete, network) easily. Containers themselves however, are created from a set

A few months ago, I set myself the challenge of writing a C compiler in 500 lines of Python1, after writing my SDF donut post. How hard could it be? The answer was, pretty hard, even when dropping quite a few features. But it was also pretty interesting, and the result is surprisingly functional and not too hard to understand! There's too much code for me to comprehensively cover in a single blog
Async Rust Is A Bad Language
But to get at whatever the hell I mean by that, we need to talk about why async Rust exists in the first place.

EDIT: A previous version of this post recommended publishConfig, operating under the mistaken belief that it could be used to override "exports" during npm publish. As it turns out, npm only uses "publishConfig" to override certain .npmrc fields like registry and tag, whereas pnpm has expanded its use to override package metadata like "main", "types", and "exports". There are a number of reasons y

You Don’t Need A UI Framework — Smashing Magazine
Developers often reach for UI frameworks like Bootstrap or Material UI, hoping that they’ll save a bunch of time and quickly build a professional-looking app. Unfortunately, things rarely work out this way. Let’s talk about it. Every now and then, someone will ask for my recommendations on UI frameworks. By “UI framework”, I mean any third-party package that is focused on providing styled UI compo
Preliminaries What Is xargs? It's an adapter between text streams and argv arrays, two essential concepts in shell. You pass it flags that specify how to split stdin. Then it generates arguments and invokes processes. Example: $ echo 'alice bob' | xargs -n 1 -- echo hi hi alice hi bob What's happening here? xargs splits the input stream on whitespace, producing 2 arguments, alice and bob. We passe
Data encryption at rest is a must-have for any modern Internet company. Many companies, however, don't encrypt their disks, because they fear the potential performance penalty caused by encryption overhead.

In 2021, containers got even better, and I was lucky enough to get a preview and present just how fast t
