俺が考える最強の「麻雀点数申告練習アプリケーション」を作ってみる ~ Pythonによる麻雀点数計算問題の自動生成と音声による点数申告 ~ - エムスリーテックブログ
こちらはエムスリー Advent Calendar 2023 1日目の記事です。 Overview エムスリーエンジニアリンググループ AI・機械学習チームでソフトウェアエンジニアをしている中村(po3rin) です。趣味は麻雀でフリー雀荘で毎年200半荘以上打ちます。好きな麻雀プロは園田賢さんです。 麻雀を始めるときに一番の障壁になるのは点数計算ではないでしょうか？ 特に符計算が初心者の関門のようです。一方私のような初中級者でも突然のレアな点数申告にまごつくことがあります。 そこで、今回はその人に合った麻雀の点数計算問題(主に符計算が焦点となる問題)を生成して、自分で点数計算&点数申告の練習をする方法を探求したのでその紹介をします。麻雀用語が少しだけ登場するので、対象読者は麻雀を少しでもかじったことのあるエンジニアの方です。 Overview 麻雀の点数計算の難しさ 現状の点数計算の練習

Building a highly-available web service without a database
If you’ve ever built a web service or a web app, you know the drill: pick a database, pick a web service framework (and in today’s day and age, pick a front-end framework, but let’s not get into that). This has been the case for several decades now, and people don’t stop to question if this is still the best way to build a web app. Many things have changed in the last decade: Disk is a lot faster
There is currently an explosion of people sharing their experiences with agentic coding. After my last two posts on the topic, I received quite a few questions about my own practices. So, here goes nothing. Preface For all intents and purposes, here’s what I do: I predominently use Claude Code with the cheaper Max subscription for $100 a month 1. That works well for several reasons: I exclusively
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
Developers are increasingly relying on AI coding assistants to accelerate our daily workflows. These tools can autocomplete functions, suggest bug fixes, and even generate entire modules or MVPs. Yet, as many of us have learned, the quality of the AI’s output depends largely on the quality of the prompt you provide. In other words, prompt engineering has become an essential skill. A poorly phrased
Unless you have been living under a rock, you have heard of this new ChatGPT assistant made by OpenAI. You might be aware of its capabilities for solving IQ tests, tackling leetcode problems or to helping people write LateX. It is an amazing resource for people to retrieve all kinds of information and solve tedious tasks, like copy-writing! Today, Frederic Besse told me that he managed to do somet

I left OpenAI three weeks ago. I had joined the company back in May 2024. I wanted to share my reflections because there's a lot of smoke and noise around what OpenAI is doing, but not a lot of first-hand accounts of what the culture of working there actually feels like. Nabeel Qureshi has an amazing post called Reflections on Palantir, where he ruminates on what made Palantir special. I wanted to

Ezno is an experimental compiler I have been working on and off for a while. In short, it is a JavaScript compiler featuring checking, correctness and performance for building full-stack (rendering on the client and server) websites.

copilot-explorer
Copilot Internals | thakkarparth007.github.io Github Copilot has been incredibly useful to me. It can often magically read my mind and make useful suggestions. The thing that surprised me the most was its ability to correctly “guess” functions/variables from surrounding code – including from other files. This can only happen, if the copilot extension sends valuable information from surrounding cod
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
ChatGPT と Whisper で発音練習アプリを作ってみた - NTT docomo Business Engineers' Blog
この記事は NTTコミュニケーションズ Advent Calendar 2023 の15日目の記事です。 この記事では、ChatGPT と 音声認識モデルの Whisper を用いた発音練習アプリケーションをご紹介します。 ChatGPT に読み上げる文章を考えてもらい、その文章の読み上げた音声を Whisper で文字起こしします。 正確に発音できていれば、正確に文字起こしできる、という考えから、 原稿と文字起こし結果を比較すれば発音練習に使えるのではないかと考えました。 実際に使ってみた結果、発音のどこが悪かったのかといったフィードバックはもらえませんが、 自分の発話した音声に対して評価がつくだけでも、結構楽しく練習できると感じました。 音声認識を活用したアプリケーションは、一般に音声認識精度がネックになると思いますが、 このアプリケーションは音声認識精度が100%ではないことを逆手に
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
Programming is an iterative process - as much as we would like to come up with the perfect solution from the start, it rarely works that way. Good programs often start as quick prototypes. The bad ones stay prototypes, but the best ones evolve into production code. Whether you’re writing games, CLI tools, or designing library APIs, prototyping helps tremendously in finding the best approach before
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

Fizz Buzz is a common challenge given during interviews. The challenge goes something like this: Write a program that prints the numbers from 1 to n. If a number is divisible by 3, write Fizz instead. If a number is divisible by 5, write Buzz instead. However, if the number is divisible by both 3 and 5, write FizzBuzz instead. The goal of this question is to write a FizzBuzz implementation that go
Front-end maximalism
Here's a question that comes up all the time: Q: I have a front end that calls into a back end. It needs to do things now, and might need to do more things later. How much filtering and preprocessing should the back-end do before it passes the data to the front end? And here's an answer I like: A: As little as possible. Some examples: Suppose you have a product page with a long list of products. T

I often come across developers who know the mechanics of Python error handling well, yet when I review their code I find it to be far from good.
