I looked at 1000s of RAG queries to figure out the problem with semantic searchhttps://news.ycombinator.com/item?id=42299349The vast majority of AI systems in production rely on basic semantic search to provide context. A single retrieval call into a vector database powers most Retrieval-Augmented Generation systems today. If you’ve tried using models like these, you know exactly how limited they are in truly understanding your data.I looked into thousands of datapoints of actual user queries to clearly classify and determine exactly where and when semantic search starts to break down and provide missing or hallucinated results.I pattern matched dozens of failure modes. Here are three of them. If you want to hear more you can reach me at pipitone@zeroentropy.dev1. Negated Semantic Queries: “Which electric vehicle articles do not include any reference to Elon Musk?”Both keyword and semantic searches will immediately retrieve specifically the electric vehicle articles that include a reference to Elon Musk.2.

Show HN: A simple automated list of gadget deals with affiliate linkshttps://justbuythe.com/deals/Searching for deals on tech stuff isn't so fun. Some sites are heavy on SEO chum and posting as many keyword-laden headlines as possible. Aggregator sites are flooded with whatever products the retailer APIs and feeds push out. I got fed up with all this while shopping online last weekend, so set about making what I'd hoped to find in the first place: a basic, somewhat-automated list of dealsIt's perfectly boring HTML with automatic price checks. There's no ads, no cookies, no signups, no writing for machines. The idea is to strike a balance between completeness and simplicity, so people can pick a decent deal without ado whenever they need one. The latest prices are fetched from Amazon, and links to the Wayback Machine are included so users can check for deceptive "yo-yo" deals.Another minimalist project of mine, txt.fyi, benefited hugely from feedback here way back when.I suppose the obvious shortcomings are:• further refinement might inevitably drag it toward more content (risk compNov 27, 2024 2:25 AM

I'd love it if people try it out and give me some feedback, at the moment it sends you an emailed validation code which might put some people off trying it, if it does put you off then please let me know, I was also toying with just having free time-limited games.Nov 24, 2024 4:17 AM

Ask HN: Real human identity/uniqueness verification for boostrapped startup?https://news.ycombinator.com/item?id=42208656For an indie startup idea, to reduce some unusual abuse that I expect, I need a way to make it hard for abusers to create another account once banned.The process for doing this has to not be needlessly creepy or invasive.But OK if people think "this is a little different...", in a non-negative way that prompts them to not just settle into default social media mode.OK if it only works for people in the US, initially.Initially, until the business takes off, it has to be either free, or near-free at a predictable flat rate.A couple ideas:* Credit Card -- Some credit card verification service, even if we don't initially charge money, or if most users go free-tier. Maybe a payment service will for free tell us that the user submitted a valid CC, and what the name on the card is. Or, less desireably, maybe we can charge a dollar or nickel to the card for signup fee, just to cover the verification (though the "whoa, this isn't totally free?!" reaction might cost us too many signups).* Phone NNov 21, 2024 9:06 PM

Show HN: I made an affordable SEO tool for Startup Foundershttps://ranqio.comI launched my second product last month (October).Ranqio was born to be an easy and affordable SEO tool for startup solofounders like me.Here is the background:I'm not an SEO expert, and I don't have +$100 to use a robust tool like SEMRush or Ahrefs, which, BTW, are incredible tools.Following online communities, I saw a lot of new entrepreneurs struggling to generate leads.Another point is the rising of the ads cost and the decrease in outbound conversion.That's why I chose this market—to address my own needs, and I think there is still space for a small solutions (yes, I'm seeing a lot of SEO tools).I built this entire product using ChatGPT in the last 2-3 months (working 1 hour/day after my job).Regarding the go-to-market strategy, I decided to start globally.Some people that I spoke asked me if it's not better to build an audience in Brazil (I'm Brazilian) first and expand later. It's an excellent question.My takeaways about this:As someone with a full-time job and a few free hours/Nov 21, 2024 6:33 PM
