A designer and an engineer shipped a production MVP in four weeks on Rails + Inertia. In this post, we share our agentic coding stack, the skills we built, and why it clicked.

まさに黒船来航といったところでしょうか。 先月、OpenAIは内部モデルを使ってエルデシュの単位距離問題を解決したと発表しました。これは、AIが初めて数学における重要な未解決問題を解いた例であるという意味で、極めて重要な意義を持つと思います。 本記事は、今、数学界で何が起こっているのかを、数学者である筆者が私見も交えつつ解説し、まとめるものです。第一部では数学的内容を、第二部では専門家による評価を、第三部では今後の展望について書いています。 主な参考文献は二つあります。 一つ目はOpenAIによる当該論文(https://cdn.openai.com/pdf/74c24085-19b

Node.js is moving to one major release a year, year-based version numbers, every release becoming LTS, and a new Alpha channel. Here is what changes.

Deno emerged as a solution to the overwhelming configuration requirements of the modern TypeScript ecosystem by offering a zero-config, single-binary experience. By integrating essential tools for formatting, linting, and testing alongside web-standard APIs, it removed the tedious setup rituals that often deterred developers. Recently, however, Deno has pivoted toward deep Node.js compatibility, supporting npm packages and traditional module structures to accelerate adoption. This shift creates a strategic risk where high compatibility might inadvertently discourage developers from targeting Deno’s unique APIs, especially as Node.js adopts Deno’s innovations like native TypeScript support and permission models. Commercial pressures may be forcing a prioritization of rapid growth and compatibility over the patient development of a truly self-sufficient, vertically integrated toolchain. While Deno remains a powerful choice, its convergence with the legacy ecosystem suggests a move away from the radical simplicity that originally defined its mission. The ongoing convergence of runtimes serves as a vital reminder of the trade-offs between technical purity and the demands of commercial viability.
