The article explains that SVG `<path>` elements use a `d` attribute containing sequential drawing commands (like "M" for move and "L" for line) to create shapes, with each command inheriting its starting position from th…
The article provides a curated list of open-source Python tools and libraries essential for building algorithmic and quantitative trading systems. Key resources highlighted include Optuna for hyperparameter optimization,…
The article describes a lightweight service designed to detect prompt injection attacks on large language models (LLMs) before they reach the production system. Unlike traditional methods that rely on sending inputs to a…
"function colors" represent genuine differences in execution contexts (e.g., async vs. sync, CPU vs. GPU) that cannot be eliminated through type systems or syntactic workarounds. It criticizes efforts toward "colorblind …
Git worktrees allow developers to create multiple working directories from a single Git repository, enabling different branches to be checked out simultaneously without context switching. This solves the problem of havin…
The article describes the author's creation of a Hugo-based "planet" aggregator after migrating from WordPress, as existing planet software was outdated or difficult to implement. Using Anthropic's Claude Sonnet 3.5, the…
The article argues that software estimates should be viewed as tools for fostering communication and transparency rather than as rigid deadlines or contracts. It emphasizes that good estimation creates visibility into wo…
The author, a software developer, finds generative AI tools like Claude highly useful for certain tasks, such as Java Spring Boot development, but notes that local models are only adequate and that the best performance r…
The core problem with both OOP hierarchies and functional programming's "make illegal states unrepresentable" approach is that they prematurely crystallize messy, evolving business domains into rigid technical type syste…
The article argues that software engineers often mistakenly prioritize uninterrupted coding time over their true job of creating impact and delivering value. It emphasizes that the most valuable work—such as catching cri…
SVG (Scalable Vector Graphics) is an image format that uses XML syntax to define drawing instructions, unlike binary formats like JPEG. When used inline in HTML, SVG elements become part of the DOM, allowing them to be s…
The article argues that defensive programming, which uses excessive conditionals and error handling to prevent failures, actually undermines software resiliency by masking errors and creating systems that silently degrad…
The article argues that developers should aim to merge at least one pull request (PR) per day by breaking work into the smallest possible valuable pieces, rather than working longer hours. It explains that frequent, smal…
This article describes a Python plugin for xbar, a macOS toolbar utility, that displays a user's daily Claude Code token usage. The script fetches usage statistics by running the `npx cusage@latest -j` command and format…
