Oh, hello. I didn't see you there. Did you ever wonder what it takes to build and launch a software product from scratch? Not a high-level summary. Not a short essay that describes a year of development. Detailed, day to day activities. A captain's log. Mistakes and pivots. Technology choices. Marketing activities. Design considerations. You might know me as the creator of SumatraPDF. I'm starting a new software product from scratch and I decided to make it an experiment of building in public. I hope to inspire others to build more software by de-mystifying the process of creation. I'm on…

Spec Driven Development approach allows to squeeze more from coding agents thanks to few strong concepts: - decomposition across two dimensions. first you generate specs in multiple steps (requirements, code analysis, design), than you split task into multiple subtasks and implement them one by one - you clear context between every step - after spec generation and after subtask implementation. this helps keep cost low and context clear and focused which boost performance - specs written to disk help with information persistency - delivering specs layer by layer help to catch early when agent…

I've worked on several projects writing and implementing specifications (particularly CLN): I've found the specs I write are much better when I quote them in the implementation, so I can see what implementers need to know. Also, when specs change in development, it's almost trivial to find where to update the code. This project is a formalization of my various hacky scripts which ensure the requirements are accurately quoted, and give coverage if any are missing. Not a major Opus, but I hope someone else finds it useful!

Hi I'm the developer of UX-App if you have any questions then fire away :) Just thought I'd give you all some background. I'm a high school teacher by day and developer by night. I was bitten by the start-up bug a few years ago and UX-App is my first product launch. In between a full time job and a 5 month old at home it has taken about 3.5 years to complete the project. I'd like to think its a unique product that holds its own against the existing competition and even has some features that no other tool has. My favorite aspect is the visual code builder which allows designers to easily…

we had hundreds of discussions with engineering leaders over the past few months, and everyone's trying to understand where they are in the AI journey. we collected all this data into a benchmark and built a free grader to let you know where you stand. you answer on a 1–5 scale (e.g., autonomy runs from "suggestions only" to "agents own multi-hour workflows across code, infra, and external systems") - takes about 5 minutes. https://agent-benchmarks.com/software-factory/ waiting for your results!
