I’ve got some bad news. Behavioral economics is dead. Yes, it’s still being taught. Yes, it’s still being researched by academics around the world. Yes, it’s still being used by practitioners and government officials across the globe. It sure does look alive… but it’s a zombie—inside and out. Why do I say this? Two primary reasons: Core behavioral economics findings have been failing to replicate

I often feel like javascript code in general runs much slower than it could, simply because it’s not optimized properly. Here is a summary of common optimization techniques I’ve found useful. Note that the tradeoff for performance is often readability, so the question of when to go for performance versus readability is a question left to the reader. I’ll also note that talking about optimization n
I joined GitLab in October 2015, and left in December 2021 after working there for a little more than six years. While I previously wrote about leaving GitLab to work on Inko, I never discussed what it was like working for GitLab between 2015 and 2021. There are two reasons for this: I was suffering from burnout, and didn't have the energy to revisit the last six years of my life (at that time)I w
Joe Tsai, Damien Neil, and Herbie Ong 2 March 2020 Introduction We are pleased to announce the release of a major revision of the Go API for protocol buffers, Google’s language-neutral data interchange format. Motivations for a new API The first protocol buffer bindings for Go were announced by Rob Pike in March of 2010. Go 1 would not be released for another two years. In the decade since that fi

Hello! I’m slowly working on explaining git. One of my biggest problems is that after almost 15 years of using git, I’ve become very used to git’s idiosyncracies and it’s easy for me to forget what’s confusing about it. So I asked people on Mastodon: what git jargon do you find confusing? thinking of writing a blog post that explains some of git’s weirder terminology: “detached HEAD state”, “fast-
The effects of remote work on collaboration among information workers - Nature Human Behaviour
Before the COVID-19 pandemic, at most 5% of Americans worked from home for more than three days per week1, whereas it is estimated that, by April 2020, as many as 37% of Americans were working from home (WFH) full-time2,3. Thus, in a matter of weeks, the pandemic caused about one-third of US workers to shift to WFH and nearly every American that was able to work from home did so4. Many technology

Don't write clean code, write CRISP code — Bitfield Consulting
I’m sure we’re all in favour of “clean code”, but it’s one of those motherhood-and-apple-pie things that no one can reasonably disagree with. Who wants to write dirty code, unless maybe it’s for a porn site? The problem, of course, is that few of us can agree on what “clean code” means, and how to get there. A rule like “methods should only do one thing”, looks great on a T-shirt, but it’s not so

How an empty S3 bucket can make your AWS bill explode

I created a single S3 bucket in the eu-west-1 region and uploaded some files there fo
If you're already somewhat familiar with promises, here are some shortcuts to save you some precious scrolling time. Introduction When writing JavaScript, we often have to deal with tasks that rely on other tasks! Let's say that we want to get an image, compress it, apply a filter, and save it 📸 The very first thing we need to do, is get the image that we want to edit. A getImage function can tak
Damien Neil and Jonathan Amsterdam 17 October 2019 Introduction Go’s treatment of errors as values has served us well over the last decade. Although the standard library’s support for errors has been minimal—just the errors.New and fmt.Errorf functions, which produce errors that contain only a message—the built-in error interface allows Go programmers to add whatever information they desire. All i
Almost exactly 18 months ago we released Tailwind CSS v1.0, which signalled a commitment to stability while continuing to push the boundaries with exciting new features in every minor release. Over the course of those 18 months we released nine minor versions that added features like placeholder styling, screenreader visibility, CSS grid, transitions, transforms, animations, layout utilities, inte
The 5-hour CDN Author Name Kurt Mackey @mrkurt @mrkurt The term “CDN” (“content delivery network”) conjures Google-scale companies managing huge racks of hardware, wrangling hundreds of gigabits per second. But CDNs are just web applications. That’s not how we tend to think of them, but that’s all they are. You can build a functional CDN on an 8-year-old laptop while you’re sitting at a coffee sho
ChatGPTはいろんなことができるが、私が興味があるのは、ChatGPTは私のためにアクションミニゲームを作ってくれるのか、ということだ。 コンピュータに自動的にアクションミニゲームを作ってもらうための試みは、だいぶ前にやった。 ChatGPTの登場によって、今度は大規模言語モデルを使うという新しいアプローチが手軽に試せるようになった。モデルに新しいゲームのアイデアを考えてもらい、そのアイデアを実現するソースコードを実装してもらえばゲームの出来上がりだ。 だが、少なくとも現状のChatGPT（今のところ私はGPT-3.5でしか試していないが）では以下の問題があるように思える。 ChatGPTに、実装可能なアルゴリズムのレベルまで詳細化された、新しいゲームのアイデアを考えさせるのは難しい ChatGPTは、今までにない新しいアルゴリズムを、ソースコードとして実装することを不得意としている

[Hacker News discussion, LinkedIn discussion, Twitter thread] A question that I’ve been asked a lot recently is how large language models (LLMs) will change machine learning workflows. After working with several companies who are working with LLM applications and personally going down a rabbit hole building my applications, I realized two things: It’s easy to make something cool with LLMs, but ver

The key to achieving world-class expertise in any skill, is to a large extent, a matter of practicing the correct way, for a total of around 10,000 hours — Malcolm Gladwell in OutliersI'm certainly not a world-class expert, but I have put my 10,000 hours of deliberate practice into programming. Here are 31 of my reflections on programming. These are reflections only about pure coding — no lessons
js実行環境であるnodeはV8を使っている jsエンジンはソースコードをどうやって実行しているのか ここからが本題です。jsエンジンの裏側をのぞいてみましょう👀 全体像 下記が基本的な流れ V8って書いてあるけど、下記の基本的な流れはエンジンによらずほとんど同じはず もちろんそれぞれのフェーズで実装の違いは在る。“Optimize & Compile it”の具体的な実装などはエンジンにより異なる Benedikt Meurer; “An Introduction to Speculative Optimization in V8”; jsの面白いところは、ASTから直接コンパイルして実行されるわけでもなく、単純なインタプリタのようにコンパイルを挟まずに実行しているわけでもないところ。それに、なんだか見慣れない”Get feedback”というフェーズさえある……！ここがJIT com
ニューコアとは、2010年代中盤から増えてきた、新しいタイプのポストハードコアです。 その音楽性を端的に表現するなら、「ポップでモダンなポストハードコア」といえるでしょうか。あるいは多くの日本人には「ONE OK ROCKをヘヴィにした音楽」という表現の方が分かりやすいかもしれません。 ハードコアの一種でありながら、美しいクリーンヴォーカル、叙情的なメロディ、キラキラとした輝度の高いギターサウンド、ピアノやストリングスを使ったドラマティックなアレンジ、シンセやデジタル的なエフェクトを多用した広がり空間処理などを特徴としています。 表層的にはオルタナティブ・ロックに近く、従来のハードコアやポストハードコアのような激しい音楽を好まないリスナーでも楽しめる、聴きやすい音楽です。 メインストリームとの対立を存在意義とするハードコアに属しながら、商業主義的なサウンドへの接近を恐れないのが、ニューコア
Windows 10とWSL2のセットアップログ
久しぶりにWindowsのセットアップを行いました。 2021-12-08から書き始めていたようです。今更ログを公開します。 もう何度もWindowsのセットアップは行っているので見返したいのと、他の人が詰まってたら助けになるようにセットアップをログに残しておきます。 近々またセットアップすることが予想されますし。何故なら近いうちにDDR5世代のPCを組んでWindows 11を入れたいからです。 いい加減セットアップはスクリプトにするべきなのかもしれませんが、 GUI操作が必要なのがまだまだ多いのと、今回はMSYS2ではなくWSL2設定で色々と違うので、ある程度手動で探っていく必要がありました。 なぜ今なのにWindows 11じゃなくてWindows 10をセットアップしたのか 私がメインにしているPCに使っているCPUが初代AMD Ryzen Threadripper 1950Xで、
As your web app matures, it becomes challenging to ensure your GUI doesn’t break with any given update. There are a lot of browsers and devices, and countless states for every one of your components. Unit tests ensure your code remains consistent, and E2E tests will ensure your system remains consistent, but neither will catch visual anomalies, layout issues, or platform compatibility issues.

React Server ComponentsとGraphQLは競合するか - cockscomblog?
Next.jsのapp directoryについて話していて、GraphQLを使う場面ではServer Componentsの魅力がいくらか落ちるよな、と思った。裏を返せば、Server Componentsが活用されるような時代ではGraphQLの重要度が下がるかもしれない。 現にServer ComponentsのRFCの「Credits and Prior Art」を見ると次のように書いてある。 Relay’s data-driven dependencies, which allow the server to dynamically choose which Client Component to use.

NGINXのコア開発者がF5の経営陣に反発、NGINXをフォークし「FreeNginx」を立ち上げ。F5の経営陣がポリシーや開発者の立場を無視したと
NGINXのコア開発者がF5の経営陣に反発、NGINXをフォークし「FreeNginx」を立ち上げ。F5の経営陣がポリシーや開発者の立場を無視したと オープンソースで開発されている軽量なWebサーバのNGINX（エンジンエックス）は、開発元であるNGINX社が2019年にF5ネットワークスに買収されたことで、それ以後はF5ネットワークスが開発を主導してきました。 参考：NGINX、F5による買収を正式発表。F5のロードバランサとNGINXのプロキシなどにより総合的なアプリケーションサービスを提供 しかし、NGINXコア開発者の1人であるMaxim Dounin氏が最近のF5ネットワークス経営陣の方針に反発し、NGINXをフォークして「FreeNginx」の立ち上げを発表しました。 Nginxのフォークは相談せずに決めた 今回FreeNginxを立ち上げたMaxim Dounin氏は、NGI

Saving Passwords In Your Browser? You Shouldn't: Here's Why
Has Chrome, Edge, or another browser given you the option to "save password"? Here's why you shouldn't, and what to do instead. Everyone should already know how important it is to use strong passwords. Ideally, you'd have a different password for each account, and all of them would be long, complex, and contain numbers and special characters. Few abide by these rules, which is understandable. Afte
When I started the Redis project more than ten years ago I was in one of the most exciting moments of my career. My co-founder and I had successfully launched two of the major web 2.0 services of the Italian web. In order to make them scalable we had to invent many new concepts, that were already known in the field most of the times, but we didn’t know, nor we cared to check. Problem? Let’s figure
This article is about what it would mean to add generics to Go, and why I think we should do it. I’ll also touch on an update to a possible design for adding generics to Go. Go was released on November 10, 2009. Less than 24 hours later we saw the first comment about generics. (That comment also mentions exceptions, which we added to the language, in the form of panic and recover, in early 2010.)
