用 Yadda 3 写好 BDD 特性文件的 7 条原则
Yadda 作者 Stephen Cresswell 提出编写 BDD 特性文件的 7 条原则：用业务语言而非技术术语描述行为，让自动化适配语言而非反过来，用具体示例而非抽象规则，把实现复杂度留在步骤定义里。 他同时指出，清晰的业务语言规范对 coding agent 同样有用——agent 需要的是意图上下文，而不是实现细节。

收藏Drizzle ORM 的事务自动传播与查询计划可测试化
Stephen Cresswell 发布两个 Drizzle ORM 扩展库。drizzle-transact 用 AsyncLocalStorage 自动传播事务，开发者无需逐层传递 tx 对象，同时从模块层面屏蔽非事务化 db 实例，防止事务内误用 db 导致部分写入提交、部分回滚的数据不一致。 drizzle-explain 将 EXPLAIN (ANALYZE, FORMAT JSON) 结果与可配置约束（maxCost、rowEstimateTolerance）做断言，让查询计划问题在测试阶段暴露而非生产环境。 两个库均无额外生产依赖，drizzle-transact 支持 Required/RequiresNew/Nested 等传播语义。

More Experiences of Vibe Coding
One of the outstanding questions from my previous post was whether code quality mattered to AI. I am now more convinced that it does. What I have observed in extended use is this: unless guided carefu...
Why Are Experiences of Vibe Coding So Polarised?
TL;DR This post explores why experiences with Generative AI assisted software development vary so dramatically. While some developers report order of magnitude productivity gains, others encounter arc...
Addendum: Open Source Contributions in Hiring
After publishing my recent article defending coding tests, I read a post by James Mahy, a genuinely kind, and exceptionally talented developer whom I ironically had the good fortune to interview some ...
In Defence Of Coding Tests
Hiring software engineers is one of the most challenging and critical responsibilities for any team. Having founded a consultancy and led hiring for other companies, I know first-hand how much is at s...
Introducing Filby: An Open Source Library for Managing Shared Reference Data
Shared reference data can be a tricky aspect of software development, especially in distributed or microservice-based architectures. Enter Filby, an open-source library that simplifies the management ...
Freedom vs. Frameworks
In his book Drive, Dan Pink highlights autonomy as one of the critical motivators for high-performing teams. Autonomy empowers engineers to innovate, solve problems creatively, and own their work. But...
Turn The Team Around!
Targets can be a double-edged sword. When poorly conceived they encourage behaviours that prioritise metrics over real success. For instance, setting a goal like “close 100 tickets this quarter” might...
NPM Search Is Broken
As an active user of npm and an author/maintainer of several libraries, I’ve recently encountered significant problems with npm’s new search experience. While I appreciate the effort the npm team has ...
Reminders as Code
In the fast-paced world of software engineering, missing a critical api-key renewal can cause significant disruption. In one event I was made aware of, the secret key for a third-party payment provide...
