Should You Stop Using Prisma? Why Database ORMs Might Be the Worst Thing That Happened to Backend Development I need to tell you something that might be controversial: Prisma, the darling of the TypeScript world, might be holding your application back. After three years of using Prisma in production, debugging performance issues that shouldn’t exist, and watching our serverless costs spiral out of

Have you ever tried to reset your password and ended up questioning your entire existence? Probably. That wasn’t your fault, but the fault of bad error prevention and handling. Error handling is one of those sneaky, underestimated parts of UX—the kind that only gets noticed when it’s done poorly. After reading this, though, you’ll know that errors are not just obstacles, they’re opportunities. Whe

The most precious things in life are memories and reflection. After we released the next generation TiDB Cloud, I think it is time for some reflection. Time flies — ten years have passed. On April 1, 2015, Max asked me, very seriously on April Fools’ Day, “Do you want to start a company together?” From that moment, I jumped on the TiDB train. The ride has been bumpy and brilliant. In these ten yea

You won’t hear this at PyCon. You won’t read it in the official Python blog. But after 2 years of Python development and watching the ecosystem closely, I’m convinced we’re witnessing the slow-motion collapse of the world’s “most popular” programming language.

For developers building AI-powered applications, bridging the gap between analytical data stores and low-latency serving engines is a common challenge. The new BigQuery import feature for Vertex AI Vector Search, now in Public Preview, offers a powerful solution. This feature is a game-changer for any developer who has struggled with the complexities of moving data from a data warehouse like BigQu

Get started with ETL Testing using this blog which is written based on real-world industry case studies and experience. Even though the above diagram is a bit of simplification, this is how most ETL workflows may look like. To put simply, ETL is an automated process to move data from source systems to target systems, involving various stages for Extract, Transform and Load sub-processes, without d

過去のデバイスドライバのバグを分類し、それをRustでどの程度防げるかを分析するという面倒な仕事からは、引き続き目を背け、Rustの型システムを活用してコンパイル時にAPI誤用によるバグを防ぐ設計例として、筆者が開発に関わっているタイマー抽象化APIを紹介します。 タイマーAPI基礎知識特定の時点を時間を表すCの型としてktime_tがあり、これは64ビット符号付き整数（s64）で表現され、単位はナノ秒です。ktime_t型は期間を表す型としても使われます。 Linuxカーネルには、下記のように複数のクロックソースが用意されていて、デバイスドライバは用途や特性に応じてクロックソースを使い分けます。例えば、realtimeクロックは補正によって時間が過去に戻る場合があるので、経過時間の測定用途には不向きです。また、独自のクロックソースを実装しているデバイスドライバもあります。 クロックソース

(This is the first of a two part series on rate limiting with Redis. This part will look at possible implementations, and the second part will look at performance) My colleague Eric has informed me that many companies are now using Redis to implement rate limiting, and has witnessed serious businesses doing this, first hand. “Redis?”, I thought. “Isn’t that that thing to cache your slow HTTP page

Do you recall when Scrum was the rage? When was it mandatory for all businesses to have certified Agile Coaches and Scrum Masters? When were daily standups and two-week sprints considered the pinnacle of software development? You might be surprised to learn that the world’s largest tech companies never truly embraced it. The signs of this trend are everywhere, and I’ve been observing it for some t

For the past three years, I have delved into the software development landscape in Japan, and one of the things I learned completely revolutionized my approach to coding. While most Western developers are busy fixated on the newest JavaScript frameworks or are engaged in the never-ending ‘tabs vs. spaces’ debate, Japanese developers have been methodically and quietly mastering the art of software

Why remote MCP deployment is inevitable, and how to do it right with Google Cloud Run. 1. Background1.1 MCP is Having a MomentThe Model Context Protocol (MCP) is absolutely everywhere right now. If you’re working with AI, you’ve probably bumped into MCP. Developed by Anthropic, it’s become the de facto standard for connecting AI assistants with external data sources and tools. In the beginning, MC

This guide is for developing for the Oculus Go, on Windows with Unity 2018.1. It is current as of June 21st, 2018. This week my company held it’s first ever internal hackathon. As soon as I heard about it, I signed up and knew exactly what I wanted to build — a VR experience for my shiny new Oculus Go. Long story short, building for the Go wasn’t as straightforward as I had hoped, but by the end o

Top 25 UX Laws Every PM Should KnowBuilding a great product isn’t just about features — it’s about how users feel when using it. As a Product Manager, understanding UX (User Experience) laws can save you from bad design decisions and make your product 10x better. Here’s a smooth and simple guide to the top 10 UX laws every PM should know. 1. Hick’s Law — Less Choices, Better DecisionsThe more opti

Tools of Chinese Ghouls- Information Manipulation and Narrative Jamming Historically, Japan and China have carried an immense burden. New deals, talks and diplomatic channels often face the horrors of their past, blocking amelioration. Triggered by the tragic murder of a 10-year-old Japanese boy in Shenzhen, China on 18th Sept 2024, these countries once again confront the complex and painful legac

What is MCP (Model Context Protocol)?The Model Context Protocol (MCP), introduced by Anthropic, defines a standardized interface for supplying structured, real-time context to large language models (LLMs). 💡 Catch up with my previous article about MCP.💡 https://modelcontextprotocol.io/Core FunctionalitiesContextual Data Injection MCP lets you pull in external resources — like files, database row

MCP サーバを経由して外部ツールに接続する AI エージェント(English version is available here) 本稿では、AI エージェントのための ”USB コネクタ” として設計されたオープンスタンダードである Model Context Protocol (MCP) と、オープンソースのAIエージェントフレームワークである Agent Development Kit (ADK) がどのように連携可能なのか、最近公開された ADK ドキュメントに基づいて、その統合パターンと開発者が考慮すべき点を解説します。 パターン 1：ADK エージェントを MCP クライアントとして使用するADK と MCP が連携する最も一般的な方法は、ADK エージェントが MCP クライアントとして機能する場合です。このシナリオでは、ADK エージェントは、MCP サーバーとして公開

SQL interview questions, especially if done during a live session, can be challenging; however, knowing in advanced which are the most common ones allows you to organize your thoughts and expose structured answers that will clearly show to your interviewer an high level of preparation. Based on my experience, these are the most common one you can’t miss if you want to increase a chance to ace your

NTTの須田です。2024年9月に開催された 第57回 情報科学若手の会 にて、「なぜオープンソースソフトウェアにコントリビュートすべきなのか」と題して招待講演させていただきました。講演内容をブログとして再編成しました。 講演資料 (PDF)なぜOSSにコントリビュートすべきなのか結論から言うと、主にOSSの持続可能性のためです。 OSSは「タダ飯」(free lunch) であるかの如く、対価を支払うことなく消費されがちです。ミートアップなどで提供される実際の「タダ飯」🍕🍣とは異なり、遠慮なく好きなだけ食べても他の人の迷惑にはなりませんが、この「タダ飯」を提供する側のことを誰かが気にかけていないと次の問題が生じます: 「タダ飯」が出てこなくなる (OSSの開発が停滞する)毒入りの「タダ飯」が出てくる (OSSにマルウェアが混入する)前者はましな方で、後者が特に事業や社会にとっての脅威

By: Charles Covey-Brandt Airbnb recently completed our first large-scale, LLM-driven code migration, updating nearly 3.5K React component test files from Enzyme to use React Testing Library (RTL) instead. We’d originally estimated this would take 1.5 years of engineering time to do by hand, but — using a combination of frontier models and robust automation — we finished the entire migration in jus
