  Backlog – a public repository of real work problemsDec 2025 · worldsbacklog.com · ▲112

  AI has made building fast and cheap, but finding the right problems still feels hard. I built World’s Backlog (https://worldsbacklog.com ) to collect real problems directly from people working inside different industries. Contributors post workflow pain, others validate it, and builders can study severity, frequency, and willingness to pay before building anything. Would love feedback from builders and people who feel real pain at work.

  I used to be just a blogger. Now I build internet products, still without code, using AI, design, and taste. I was building in public on X for last 2 months. And honestly, I got tired of how it became performative and started to feel fake. I shipped 2 products. Both failed to get any real traction. I kept sneaking into popular builders’ profiles, hoping to learn how they do it. One thing I kept seeing everywhere, product launch directories. I thought here is the scope. So I started building one. Same UI like the rest. Nothing special. Suddenly one day when it was half built, I realized…

  Hey HN! I am a FE dev who is working at a software agency and im making 2-3 estimates per week. Creating estimates is painfull manual proccess, where you have to read a lot of .docx like RFP, SRS etc. This was really tiring for me Also in agency where im working we make estimates in google spreadsheets which is another pain, trying to drag something, copy, duplicate can really mess up the whole layout So i just wanted tool that can just automate this a bit. I just started researching and I couldnt find anything good enough for my usecase. So I made a tool for creating estimates with AI. I…

  Needle: We Distilled Gemini Tool Calling into a 26M Model▲776

  Hey HN, Henry here from Cactus. We open-sourced Needle, a 26M parameter function-calling (tool use) model. It runs at 6000 tok/s prefill and 1200 tok/s decode on consumer devices. We were always frustrated by the little effort made towards building agentic models that run on budget phones, so we conducted investigations that led to an observation: agentic experiences are built upon tool calling, and massive models are overkill for it. Tool calling is fundamentally retrieval-and-assembly (match query to tool name, extract argument values, emit JSON), not reasoning. Cross-attention…
