I started programming in Rust several years ago, and it has gradually changed the way I design programs in other programming languages, most notably in Python. Before I started using Rust, I was usually writing Python code in a very dynamic and type-loose way, without type hints, passing and returning dictionaries everywhere, and occasionally falling back to “stringly-typed” interfaces. However, a

REST API Design Best Practices Handbook – How to Build a REST API with JavaScript, Node.js, and Express.js
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 few examples is goo
Speculation in JavaScriptCore
This post is all about speculative compilation, or just speculation for short, in the context of the JavaScriptCore virtual machine. Speculative compilation is ideal for making dynamic languages, or any language with enough dynamic features, run faster. In this post, we will look at speculation for JavaScript. Historically, this technique or closely related variants has been applied successfully t
How to debug C and C++ programs with rr | Red Hat Developer
The common theme in many time-travel movies is to go back in time to find out what went wrong and fix it. Developers also have that desire to go back in time and find why the code broke and fix it. But, often, that crucial step where everything went wrong happened long ago, and the information is no longer available. The rr project lets programmers examine the entire life of a C or C++ program run
こんにちは。BASE BANK株式会社 Dev Division にて、 Software Developer をしている永野（@glassmonekey）です。 弊社ではAWS Lambdaを活用する機会が増えまして、 最近メジャーアップデートのあった「AWS SAM CLI」を使ってリリースフローの改善にチャレンジしてみました。 そこで、samコマンドで作成したサンプルプロジェクトをローカルで実行しデプロイする方法を紹介します。それに加えて、現状BASE BANKチームで行っている代表的な運用設定をご紹介します。 今回記事作成に際して、サンプルプログラムを用意しているのでもしよければ手元でご確認ください。 なお、今回LambdaにはGoを採用しました。検証に使用した環境は以下の通りです。 macOS: 10.15.x (Catalina) SAM CLI: version 1.2.0
I recently realized stdout is much faster than stderr for Rust. Here are my findings after diving deep into this rabbit hole. I have been using the terminal (i.e. command-line) for most of my day-to-day things for a while now. I was always fascinated by the fact that how quick and convenient the command-line might be and that's why I'm a proponent of using CLI (command-line) or TUI (terminal user

This all started with a blog post back in 2020, from a tech curiosity: what's the fastest way to scale containers on AWS? Is ECS faster than EKS? What about Fargate? Is there a difference between ECS on Fargate and EKS on Fargate? I had to know this to build better architectures for my clients. In 2021, containers got even better, and I was lucky enough to get a preview and present just how fast t
Webpack 4 was released in February 2018. Since then we shipped a lot of features without breaking changes. We know that people dislike major changes with breaking changes. Especially with webpack, which people usually only touch twice a year, and the remaining time it "just works". But shipping features without breaking changes also has a cost: We can't do major API or architectural improvements.

Hello! I wrote a comic last week called “life of a DNS query” that explains how DNS resolvers work. In this post, I want to explain how DNS resolvers work in a different way – with a short Go program that does the same thing described in the comic. The main function (resolve) is actually just 20 lines, including comments. I usually find it easier to understand things work when they come in the for

Companies Using RFCs or Design Docs and Examples of These
RFCs - requests for comment - or Design Docs are a common tool that engineering teams use to build software faster, by clarifying assumptions and circulating plans earlier. There are some similarities between writing automated tests for your code, and writing RFCs before you start working on a non-trivial project: Software engineers who write tests for their code - and ask for code reviews on it -

CUPID—for joyful coding
What started as lighthearted iconoclasm, poking at the bear of SOLID, has developed into something more concrete and tangible. If I do not think the SOLID principles are useful these days, then what would I replace them with? Can any set of principles hold for all software? What do we even mean by principles? I believe that there are properties or characteristics of software that make it a joy to
When people say “debuggers are useless and using logging and unit-tests is much better,” I suspect many of them think that debuggers can only put breakpoints on certain lines, step-step-step through the code, and check variable values. While any reasonable debugger can indeed do all of that, it’s only the tip of the iceberg. Think about it; we could already step through the code 40 years ago, sure
