AN INTERACTIVE GUIDE TO SVG PATHS

This is an interactive guide to SVG paths, focusing on the path element and its various commands for drawing shapes. It covers basic commands like Move and Line, then goes into Bézier curves (quadratic and cubic) and the complex Arc command, explaining each parameter with interactive examples. The guide also covers extra details like closing paths, relative commands, and chained curves.

CREATIVE WAYS TO FUND OPEN SOURCE PROJECTS

Open source projects are often underfunded, leading to maintainer burnout, but innovative revenue models are starting to show up. The Wix Toolset uses an "Open Source Maintenance Fee," which charges users for issue reporting and pull requests based on company size, providing income for maintainers. Another example is Astral's uv package manager, which offers a free version and a paid, enterprise-focused registry called pyx with more features.

YOU SHOULD ADD DEBUG VIEWS TO YOUR DB

Creating debug views in your database can simplify complex queries and improve debugging efficiency. These views predefine joins and include relevant information, making it easier to find specific data based on various criteria. By making these views, it removes the need to repeatedly write lengthy queries.

AWS CEO SAYS USING AI TO REPLACE JUNIOR STAFF IS 'DUMBEST THING I'VE EVER HEARD'

AWS CEO Matt Garman dismissed the idea of replacing junior staff with AI as the dumbest thing he's ever heard, arguing that these employees are inexpensive and AI-savvy. Instead, it's important to continue to hire and train junior developers to create a future workforce with critical thinking and problem-solving skills.

THE UNBEARABLE SLOWNESS OF AI CODING

When first coding with Claude Code, this dev had a speed boost in his coding tasks. However, as his app grew, the review and debugging process became painstakingly slow, despite using multiple instances of Claude Code simultaneously. He found himself spending a lot of time as a QA engineer, fixing issues generated by Claude, including hallucinations about library features.

BUILDING AI PRODUCTS IN THE PROBABILISTIC ERA

The industry is experiencing a shift from deterministic software, where inputs predictably map to outputs, to a probabilistic era driven by AI. Traditional methods of building and managing software based on pre-defined features and measurable funnels are becoming obsolete as AI models exhibit emergent, unpredictable behaviors. To succeed, companies must adopt an empirical, scientific approach, focusing on managing uncertainty and understanding user behavior through user trajectories.

MY AI HAD ALREADY FIXED THE CODE BEFORE I SAW IT

Compounding engineering is a development approach where AI tools learn from every code review, bug fix, and pull request, building systems that improve themselves. By codifying preferences and architectural decisions, engineers can train AI agents like Claude to automate tasks and enforce consistent standards. This method turns production errors into permanent fixes.

GPT-5: IT JUST DOES STUFF

GPT-5 automatically selects the right model for each task and proactively suggests solutions rather than just answering questions. It's possible to give it a vague coding prompt and receive a fully functional app with features never requested. This shows a shift in AI becoming more proactive over time.
