Wow, my daughter just text me that the airline asked for 5 volunteers to get off the plane for $1200 free lodging and a free flight tomorrow. The problem was Weight on the plane. A family of 5 took that amazing deal.

Thinking of introducing a cool UI/UX pattern into your app? Look at the leaders in the space (like AirBnb on mobile, or Netflix on desktop / TV) If they don’t do it, it means they’ve probably run a test and found that it isn’t effective! No need to reinvent the wheel

tbh coding agents are still net-bad at real frontend tasks ❌ figma to code ❌ React.useEffect ❌ complex interactions / flows ❌ animations ❌ web performance ❌ responsive design ❌ ARIA ❌ drag and drop ❌ virtualized lists ❌ async data fetching ❌ mobile gestures

In an era where LLMs are allowing devs to write more and more code, I feel like @github should be prioritizing fixing the clunky dinosaur that is their PR + code review feature set, especially for large changsets…

Very cool concept! @Pragmatic_Eng reported recently that Meta has begun to roll out a similar concept internally, known as "trajectories"

a mockup: doing PR reviews by seeing a programmers chain of prompts! it also encourages devs to be deliberate with how they instruct llms as they become more capable, and poor human instructions + context ends up being the reason why code doesn't work

monthly stack overflow questions over time. 3710 questions last month, just slightly under the 3749 from the first month of it being public. human software engineering had a good run, and now we've come full circle.
