New best story on Hacker News: Show HN: Glasses to detect smart-glasses that have cameras
Show HN: Glasses to detect smart-glasses that have cameras
446 by nullpxl | 162 comments on Hacker News.
Hi! Recently smart-glasses with cameras like the Meta Ray-bans seem to be getting more popular. As does some people's desire to remove/cover up the recording indicator LED. I wanted to see if there's a way to detect when people are recording with these types of glasses, so a little bit ago I started working this project. I've hit a little bit of a wall though so I'm very much open to ideas! I've written a bunch more on the link (+photos are there), but essentially this uses 2 fingerprinting approaches: - retro-reflectivity of the camera sensor by looking at IR reflections. mixed results here. - wireless traffic (primarily BLE, also looking into BTC and wifi) For the latter, I'm currently just using an ESP32, and I can consistently detect when the Meta Raybans are 1) pairing, 2) first powered on, 3) (less consistently) when they're taken out of the charging case. When they do detect something, it plays a little jingle next to your ear. Ideally I want to be able to detect them when they're in use, and not just at boot. I've come across the nRF52840, which seems like it can follow directed BLE traffic beyond the initial broadcast, but from my understanding it would still need to catch the first CONNECT_REQ event regardless. On the bluetooth classic side of things, all the hardware looks really expensive! Any ideas are appreciated. Thanks!

I’ve been a part of this community for fifteen years. Despite the yearly bemoaning of HN’s quality compared to its mythical past, I’ve found that it’s the one community that has remained steadfast as a source of knowledge, cattiness, and good discussion. Thank you @dang and @tomhow. Here's to another year.

New best story on Hacker News: Show HN: I built an interactive HN Simulator
Show HN: I built an interactive HN Simulator
460 by johnsillings | 202 comments on Hacker News.
Hey HN! Just for fun, I built an interactive Hacker News Simulator. You can submit text posts and links, just like the real HN. But on HN Simulator, all of the comments are generated by LLMs + generate instantly. The best way to use it (IMHO) is to submit a text post or a curl-able URL here: https://news.ysimulator.run/submit . You don't need an account to post. When you do that, various prompts will be built from a library of commenter archetypes, moods, and shapes. The AI commenters will actually respond to your text post and/or submitted link. I really wanted it to feel real, and I think the project mostly delivers on that. When I was developing it, I kept getting confused between which tab was the "real" HN and which was the simulator, and accidentally submitted some junk to HN. (Sorry dang and team – I did clean up after myself). The app itself is built with Node + Express + Postgres, and all of the inference runs on Replicate. Speaking of Replicate, they generously loaded me up with some free credits for the inference – so shoutout to the team there. The most technically interesting part of the app is how the comments work. You can read more about it here, as well as explore all of the available archetypes, moods, and shapes that get combined into prompts: https://news.ysimulator.run/comments.html I hope you all have as much fun playing with it as I did making it!

After down detector went down with the rest of the internet during the Cloudflare outage today I decided to build a robust, independent tool which checks if down detector is down. Enjoy!!

Hey all, Throwaway in case this is assumed to be politcally motivated. I spent some time organizing the Eptstein files to make transparency a little clearer. I need to tighten the data for organizations and people a bit more, but hopeful this is helpful in research in the interim.

Tell HN: X is opening any tweet link in a webview whether you press it or not
398 by stillatit | 358 comments on Hacker News.
Just saw the CEO of Substack celebrating traffic from X/Twitter shooting up thinking they stopped suppressing tweets with links[0]. Actually, this traffic is because now any time you open a tweet with a link, the in-app webview loads in the background, and displays when you press the link. I run an ecom store that gets a lot of its customers from Twitter. I was also shocked to see my traffic double or triple overnight and thought the algorithm had blessed me and my business. Soon realized what was actually happening. Thought other traffic-monitors might appreciate this explanation. Meanwhile Nikita Bier is pretending they never suppressed tweets with links to begin with, offering the alternative explanation: "a common complaint is that posts with links tend to get lower reach. This is because the web browser covers the post and people forget to Like or Reply. So X doesn't get a clear signal whether the content is any good"[1]. A bit of a rewriting of history since Elon and his mom both tweeted about how it wasn't fair to use his platform to promote other links/platforms, even banning people who shared profiles of other social networks (including Paul Graham for a period). They suppressed all links shortly after. [0] https://ift.tt/f1w5ZRH [1] https://ift.tt/9ZfSn5c

Ask HN: Who uses open LLMs and coding assistants locally? Share setup and laptop
319 by threeturn | 179 comments on Hacker News.
Dear Hackers, I’m interested in your real-world workflows for using open-source LLMs and open-source coding assistants on your laptop (not just cloud/enterprise SaaS). Specifically: Which model(s) are you running (e.g., Ollama, LM Studio, or others) and which open-source coding assistant/integration (for example, a VS Code plugin) you’re using? What laptop hardware do you have (CPU, GPU/NPU, memory, whether discrete GPU or integrated, OS) and how it performs for your workflow? What kinds of tasks you use it for (code completion, refactoring, debugging, code review) and how reliable it is (what works well / where it falls short). I'm conducting my own investigation, which I will be happy to share as well when over. Thanks! Andrea.
