Roblox parental controls are a dystopian security disasterhttps://news.ycombinator.com/item?id=48690591My 14 year old daughter got hacked by someone who was able to add themselves as a "linked parent" to her account. I'm not even sure that this person got ahold of her password in the first place. All this happened on Wednesday morning (6/24/26) but on the day it happened I did not recieve a single email about any of this even though the account is tied to my email address (verified). Usually if there is a new log in on an unrecognized device I would have gotten an email about it, but nothing was sent on 6/24 to me. I suspect that even if two factor authentication was already added to her account it would have done nothing, because there was a two factor authentication passkey added to her account which was definitely not set up by her. But by using that newly created authentication passkey the "linked parent" was clearly able to log into her account (which I didn't get any emails about), go into every game and transfer out every last collectable thing she had collected since 2020.And woJun 26, 2026 7:02 PM

Ask HN: Options for an independent AI researcher with strong results?https://news.ycombinator.com/item?id=48689261I'm outside the AI industry, outside of academia, and no easy contacts into relevant areas. My background lends itself to exploring AI & reasonable level of care checking results. I was focusing on building practical useful things for a portfolio to help change industries mid-career, but that has become something a little different now.The exploration has led to an analytical framework that appears useful more broadly for looking at neural representational models. (It's not a model architecture or training method, benchmark, or prompt engineering.) It is a way of analyzing internal representations through the mapping of structure-preserving connections, to transport them to a frame of reference outside the model, exposing some stable relationships, while not being model-specific or require training something else.It has survived attempts at invalidation, generated useful predictions and functioning interventions, and has continued to reveal additional applications the more I do.

Show HN: BetterDB, MIT Valkey-native context layer for AI agentshttps://github.com/BetterDB-inc/monitor/tree/master/packagesToday we released an open, Valkey-native context layer for AI agents as part of our packages at BetterDB (agent memory, semantic + multi-tier caching, typed retrieval) that run on a Valkey instance no matter where it is - no vendor lock-in. We even started provisioning Valkey instances starting today. Packages are shipped on npm and PyPi.Why we made it: BetterDB originally started as a monitoring and observability platform for Valkey, Redis and any RESP compatible db. This is still the core of the product, but in the process of building this, we kept seeing that one of the fastest-growing uses of Valkey was AI - vector store and cache behind agents and RAG. So about a month and half ago we published MIT semantic and agent cache libraries for that, with the agent cache library not even requiring any modules and being able to run on vanilla Valkey. Today we are extending this to agent memory. Because we started with observability, it also runs everywhere - every cache, memory and retrievJun 26, 2026 3:16 PM

Show HN: I built a tool that matches Founders to VCs based on their pitch deckhttps://investormatch.proHey HN,I am a VC and 3x venture-funded Founder. VCs and Founders are both playing a low-probability matching game. Better targeting both ways is the way to solve this problem for both parties.So I build Investor Match - Founder uploads a pitch deck (or paste a Docsend link), and it returns 20 ranked investor matches with fit scores, contact details and pre-drafted outreach emails. There is also a deck Teardown feature to improve your deck before sending to Investors. We launched in Jan. and over 3,000 founders have run their decks. There are over 10,000 VCs in the database. Founders have reported over $100M in commitments from matches so far.When I was a founder, I was scraping Crunchbase and Techcrunch for investors and cold-emailing them, generally without enough context on stage, sector fit, or what they actually invest in. Most prior matching systems were dumb key-word matches (you are B2B, Investor X invests in B2B so match). Investor Match does full symentac match after having reJun 26, 2026 1:34 PM

Show HN: Ponder – the best articles and essays on the internethttps://www.readponder.com/Hello HN,I love to read articles, but I have trouble finding the bangers that really make you think.I want to be able to organize a huge database of articles and filter it by category then order it by quality to find the best ones worth my time. There's iMDb for film, Goodreads for books, AOTY for albums but nothing for articles and essays. That was the idea, and I've got it up and running.Where it's at honestly: ~500 articles cataloged, a small handful of active users, and very few ratings yet. It's early. I'm a solo builder and I'm hoping to find other people who find the website useful and have the same passion that I do for good longform. It is a user-fed database, so it needs a few more people before it will start to thrive.What I'd love feedback on:-Yes, I used AI to generate the website code. Is this a turn-off? Is it obvious? -Would you use a website like this to keep a log or find good reads? -Are there any articles that you've read that you still think about?Jun 26, 2026 12:56 PM

Show HN: Unofficial cross-platform Shure MV clienthttps://github.com/Humblemonk/shurectl(Disclosure: This tool makes my repo obsolete. I am not the code author.)A few years ago, I used Wireshark to sniff and decode the protocol for the Shure MVX2U, a USB/3.5mm adapter for professional microphones. Shure did not have a method for changing adapter settings in Linux or Android, and I didn't have a Windows/Mac computer, so I wrote a CLI client in Python plus an Android app. The CLI tool had a few small bugs, and I could never figure out how to change settings in one endpoint, monitor the audio endpoint in the Python script, and listen in a different app at the same time. This didn't bother me much, because the main goal was for my partner and I to adjust mic gain (auto gain and compression were less-than-ideal) and toggle phantom power from our phones for music and theater projects.(I've since switched to a heavily modified Zoom F3 with direct-connect Schoeps CMC1 amps in M/S configuration; it's nearly the same dimensions/weight, a drastically lower noise floor, onboard recorJun 26, 2026 9:58 AM

Show HN: Appaca – AI Workspace for Operatorshttps://www.appaca.ai/Appaca is my third pivot.A couple of years ago, I started working on an idea on no-code platform that generates code. The goal is to help devs and agencies ship products faster for their clients. I went through Antler startup accelerator and got initial funding. I was working on the right problem, but wrong solution. Instead of no-code, I should have jumped into LLM a lot earlier. I felt defeated when Lovable, Base44, and Bolt came out strong, showing the world what LLMs can do in software development. No one cared about my product anymore.I pivoted my startup second time after that, to an AI agent builder for businesses. After my first MVP launched, I got some decent tractions with that. A lot of people wanted to make AI agents that they can monetise. So, I focused on making a platform that helps them build and ship monetisable AI agents. The product made some revenues, but the churn was super high. Later, more mature companies like Zapier and N8N started their AI agents. My competitoJun 26, 2026 4:54 AM

Ho progettato un'infrastruttura logistica per azzerare lo spreco alimentarehttps://news.ycombinator.com/item?id=48682173Ciao a tutti,Da qualche mese sto lavorando al design di un'infrastruttura logistica e tecnologica chiamata Zero Waste Bridge. L'obiettivo è ambizioso: prendere il cibo fresco invenduto della grande distribuzione/ristorazione a Milano, abbatterlo termicamente e spedirlo nelle zone a criticità alimentare in Africa usando risorse logistiche già esistenti ma totalmente inutilizzate.Ho calcolato che il costo finale per singolo pasto salvato e consegnato si aggira intorno ai 0.23 €.So che sembra la classica idea utopica da "salvatori del mondo", ma dietlo c'è un modello ingegneristico ed economico molto rigido. Siccome so che su.... r/italystartup ci sono fior fior di ingegneri, esperti di supply chain e programmatori, vi presento il progetto sotto forma di Q&A (Domande e Risposte) sulle criticità tecniche.Smontatemi l'idea nei commenti, ho bisogno di capire dove sono i bug strutturali.Jun 26, 2026 3:57 AM

Show HN: MCP Server for a UK Meat Price Comparison Sitehttps://meat.offer-spider.comPosted previously about the price scraping site I pulled together that matches meat from a variety of online butchers to an internal shared taxonomy to make it easier to see what's actually a good price vs. a temporary price fluctuation.I've now got over a year of data so there are some interesting patterns appearing in various product offerings (some of it seasonal, some of it as expected appears to be reactionary to price changes on competitors).I just wanted to get the best price for meat that I enjoy smoking on my Kamado, but it got a little out of hand, so now there's a full on basket comparison (get the cheapest basket in one shop for your chosen products) and grouped cut analysis over time (to see how price is changing and if it's genuinely a good price right now).Because it seems like everyone's doing it these days (and UI is so painful to craft and keep up to date), added an MCP server so you can ask your AI about the data directly instead of clicking around the site.

Show HN: OpenKnowledge – open source AI-first alternative to Obsidian/Notionhttps://github.com/inkeep/open-knowledgeHi HN, Nick here. We’re launching OpenKnowledge (https://openknowledge.ai/), a “what you see is what you get” markdown editor that has direct integrations with Claude, Codex, and other agents. Available as MacOS app or Web UI+CLI. Fully free/local and OSS.We built this because we wanted a Notion-like experience for writing and sharing markdown files across our team. Obsidian is the best alternative we tried, but found it doesn’t have a true WYSWIG UI and it didn’t integrate well with Claude/Codex outside of community plugins.So we built OpenKnowledge. It takes shape as:1. A MacOS app with a file navigator, the WYSIWYG editor, and link explorer.2. Integrations with the Claude, Codex, and Cursor desktop apps. The agents can open an OpenKnowledge editor within their embedded web browsers for a side-by-side experience.3. Built-in mcps, skills, and RAG for LLM-wiki and “AI Second Brain” scenarios + spec writing4. An embedded terminal and CLI for TUI-first usersOSS stack includes: Tiptap/proJun 25, 2026 4:04 PM

Show HN: Contraband – Ticketed VR cinema for indie and AI-made filmshttps://contraband.watchPeople who makes films don't have it easy. In a typical scenario - the team that produced the film makes 15% of the topline revenues. The Distributor takes 35%. And the theatre (the exhibitor) takes 50%.So even in a scenario like Obsession where the movie is making a rocket ride, the filmmakers were capped at $50M (15M upfront + 15%). The Distributors and theatres get the upside of the $330 million.In the startup world, we get upset about appstores charging 30% :)The situation gets worse for Indie films and more so for people who are using AI tools to tell stories. Films that got made, got finished, and then have nowhere to go because the distribution infrastructure wasn't built for them. That's increasingly true for indie films. It's almost entirely true for AI-made films right now.CONTRABAND is our attempt to fix that. It's a scheduled, ticketed VR cinema that runs inside a Meta Quest headset.

Why directory jumpers should use exponential moving sums instead of frecencyhttps://news.ycombinator.com/item?id=48674366Directory jumpers such as z.sh and zoxide need to rank candidate directories from a stream of past navigation events. Most implementations use some form of frecency: a score combining historical visit count with recency.The details vary, but the basic idea is always score = frequency × recency where frequency measures how often a directory has been visited and recency depends on last visit time. After evaluating some tools, I have become convinced that this scoring model is wrong. The reason concerns the structure of the formula itself.## Problem 1: historical visits never really disappearSuppose a directory visited many times before but now dormant for months. A frecency system typically preserves the large historical count and only reduces the recency term. The directory therefore retains a large amount of "latent weight".When visited again, the recency term resets while the historical count remains intact. Consequently, a directory that has been irrelevant for months can jump straigJun 25, 2026 2:53 PM
