   TypeMyVibe – Find your Personality type from Reddit, X, or chat data▲5

   TypeMyVibe analyzes your Reddit or X profile (just by username), or you can upload a WhatsApp/Instagram chat to get a personality report with MBTI, Enneagram, Big 5, and more. I built this because I’ve always been fascinated by personality theories, but also frustrated with how easily they’re biased. Most tests depend on self-perception, which changes with mood. I wanted to see if analyzing real language could reveal a person’s true type. What made me to actually build it was when my sister got the same MBTI as me (INTP).

   Using stylometry to find HN users with alternate accounts▲676

   Author here. This site lets you put in a username and get the users with the most similar writing style to that user. It confirmed several users who I suspected were alts and after informally asking around has identified abandoned accounts of people I know from many years ago. I made this site mostly to show how easy this is and how it can erode online privacy. If some guy with a little bit of Python, and $8 to rent a decent dedicated server for a day can make this, imagine what a company with millions of dollars and a couple dozen PhD linguists could do. Here's Paul Graham:…

    Subreddit Finder - Trained on 4M Reddit Posts from 4K Subreddits▲152

    We built Valohai LLM for tracking and comparing LLM evaluation results. Whether your evals live in notebooks and spreadsheets, or you're using an observability tool that wasn't built for comparison, this gives you a purpose-built eval comparison dashboard. Run evals with a Python library (pip install valohai-llm), results stream in, and you can compare up to 6 configurations side by side. Group by any dimension (model, category, difficulty) to see where each model excels. It doesn't do tracing or production observability, for now just eval tracking and comparison. What's cool is that you can…
