I scraped Reddit to find the most controversial chef knife
I wanted to quantify the endless "which knife should I buy" debates on r/chefknives, so I built a data analysis pipeline to get some real answers. The project is a 5-phase system built with Node.js. It first uses Fuse.js for fast, typo-tolerant fuzzy matching of ~450 known brands and ~8,700 models. The remaining text is then passed to an LLM (via OpenRouter) for discovering new, unknown entities and performing sentiment analysis on every mention. I ran it on over 1,000 threads, totaling more than 25,000 comments. A few interesting findings: The Underdog: Budget-friendly Tojiro has a…

I built a knife steel comparison tool2025 · new.knife.day · ▲146Hey HN! I'm a bit of a knife steel geek and got tired of juggling tabs to compare stats. So, I built this tool: https://new.knife.day/blog/knife-steel-comparisons/all It lets you pick steels (like the ones in the screenshot) and see a radar chart comparing their edge retention, toughness, corrosion resistance, and ease of sharpening on a simple 1-10 scale. It's already been super handy for me, and I thought fellow knife/metallurgy enthusiasts here might find it useful too. Would love to hear your thoughts or any steel requests! Cheers!

Hey HN! About a year ago i stumbled upon the world of swords, knives, and EDC gear. A weirdly addicting (and expensive) hobby to have. Back then i noticed something, it was quite tedious to easily sift and search through knives based on length, steel, brand, and what not to find the knife for me. There were some great youtube channels that helped me pick out what i wanted however i had to sit through multiple 30 minute videos just to review 10-15 knives or so each. Recently i've been having a little trouble sleeping so i decided to pickup a new passion project to work on late at night,…
Subreddit Finder - Trained on 4M Reddit Posts from 4K Subreddits2020 · valohai.com · ▲152We 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…

Hey there HN ! I'm so excited to show you the platform I built! It's a product review website that's all about community and video reviews. I wanted to create a space where people could share their personal experiences and opinions on products, so others could make informed decisions based on real-life experiences. I noticed that there were a lot of fake reviews on other platforms, and I knew that people wanted a more reliable and trustworthy source for product reviews. That's why I decided to create a website that would prioritize genuine, honest curated reviews from real people. Our…

I went down the rabbit hole on a side project and ended up building this: Strange Attractors(https://blog.shashanktomar.com/posts/strange-attractors). It’s built with three.js. Working on it reminded me of the little "maths for fun" exercises I used to do while learning programming in early days. Just trying things out, getting fascinated and geeky, and being surprised by the results. I spent way too much time on this, but it was extreme fun. My favorite part: someone pointed me to the Simone Attractor on Threads. It is a 2D attractor and I asked GPT to extrapolate it to…

Autism Simulator▲779Hey all, I built this. It’s not trying to capture every autistic experience (that’d be impossible). It’s based on my own lived experience as well as that of friends on the spectrum. I'm trying to give people a feel for what masking, decision fatigue, and burnout can look like day-to-day. That’s hard to explain in words, but easier to show through choices and stats. I'm not trying to "define autism". I’ve gotten good feedback here about resilience, meds, and difficulty tuning. I’ll keep tweaking it. If even a few people walk away thinking, "ah, maybe that’s why my coworker struggles in those…
