Will AI Replace Programmers? A Structured Analysis of AI, Code Quality, and the Future of Software Work

Introduction The question “will AI replace programmers?” is usually posed and answered badly. The optimistic camp says AI is just autocomplete; the pessimistic camp says coders are obsolete. Both miss what is actually happening. This […]

Agile Quietly Shifted the Risk to the Client — and Now Clients Are Asked to Act Like Engineers

Agile didn’t just change how software gets built. It changed who carries the risk. And most clients were never told. Here’s what Agile quietly hands to the client: 1. Ownership of priorities.In Scrum, the Product […]

Hidden Debt in Outsourced Software: Why Fees Rise, Systems Get Rebuilt Early, and What to Do About It

If you outsource your software, hidden debt will raise your maintenance fees and force an early rebuild — and by the time it’s visible, fixing it is expensive for everyone. Including the vendor. Here’s why […]

Beyond Scrum and Kanban: Why Popular Agile Methods Fail Serious Software Projects—and What to Do Instead

Introduction: The Uncomfortable Question Software projects are still failing at alarming rates—despite decades of “Agile adoption.” Engineers are burning out in London, Bangalore, New York, and Tokyo. Morale is collapsing. Quality is declining. The methodologies […]

Is CI/CD Your Savior? Think Again.

A pragmatic look at the hidden costs, the small-batch myth, and why user trust matters more than deploy frequency. I. Introduction “CI/CD will save you money. It will make your team faster. It will eliminate […]

It’s Time to Rethink Agile. The Albatross Method Is the Advanced PM’s Choice.

Why project managers who have outgrown reactive rituals are turning to proactive, component-based engineering. Introduction: A Global Crisis Beneath the Agile Banner Software projects are still failing at alarming rates—despite decades of “Agile adoption.” Engineers […]

Understand Relu as a Piecewise Function

Relu is an activation function defined as:$$Relu(x)=\begin{cases}x, & x > 0 \\0, & otherwise\end{cases}$$. This function has an interesting property that it can act like an open/close switch. To see why, suppose $\vec{x}$ is a […]

Understand Why A Sole Linear Layer Does Not Classify Well

In deep neural network, the most frequently used component may be the linear layer. However, the linear layer itself does not work well as a classifier. In this article, I intend to explain why from […]

バイブコーディングのブームがそろそろ過ぎ去ろうとしているのではないか

動画サイトでは、まだまだバイブコーディングの話題で盛り上げています。しかし、すでにいくつかの楽観視できない結果でデータとして出ています。最近は下記の結果が目に飛び込んできました。 The AI Productivity Boom that Wasn’t | L&DeepDive 要約しますと、ベテランプログラマーであれば、生成AIを使って、20%早くなったという錯覚が生じて、実際は20%遅くなったという結果になった。 これでは、バイブコーディングのきれいな泡はほぼ弾けてしまいました。 バイブコーディングでは、もともとテクにある負債を神速に積み上げることが予見されています。今回の結果を加えて、生産性を落としていることも再度確認されました。 もちろん、生成AIは一つの発展方向ですが、実際のビジネス環境というすごく複雑な文脈(コンテキスト)をどうやって一つの生成AIに低コストに詰め込むことは相当難しいでしょう。 Claude Code社では、80%-90%のコードはAIに書かせていると宣言したことですが、あれば、自社製品作成の一環としてもみなすことができ、通常のプロジェクト開発と比べて、コスト上昇に対する容認度はかなり高いでしょう。 バイブコーディングはプロダクションコードの主力になるまでまだまだ時間がかかりそうですね。

I made a browser extension that helps generate low-code test cases.

Are you a pure programming lover? Or you are someone who dares not to challenge programming? I’d prefer to choose the latter as testers. The reason is that the people who are not programmers tend […]
