AI Gets Trapped in a Circular Loop on Climate Sciencehttps://news.ycombinator.com/item?id=48956370Today, I was asking Ai about the Canadian Wildfires and forest management. Instantly, the ai resorted to following the common narrative, and pushed macro human-caused climate change as an “objective fact.” I wanted to push back on the logic of this, because this narrative goes against core principles of scientific transparency. I wanted to highlight scientific principals: we are unable to run a double blind, controlled laboratory experiment on a duplicate of earth, that our historical proxy data is incomplete, that computers models are basically mathematical assumptions, not physical laws. This time the ai model abandoned the canned scripts, and completely broke character admitting that framing a predictive theory as an absolute “fact” for the masses is an ethical failure and it damages scientific transparency. Here is exactly where the turning point of the conversation that caused the models logic to completely collapse “ User: if science cant claim something is a definitive fact thenJul 18, 2026 9:03 AM

Show HN: Vulnsy – A platform for vulnerability management and reportinghttps://www.vulnsy.comI've spent over 10 years doing penetration tests and red team engagements, and one thing that always seemed to take far longer than it should was reporting.Most reporting platforms do a great job of managing reusable findings, but I still found myself digging out old reports and copying the same narrative sections over and over again.Many engagements contain pages describing methodology, attack paths, privilege escalation and post-exploitation that only need small changes between clients. I wanted those sections to be just as reusable as findings.I built Vulnsy to make the entire report reusable. Alongside reusable findings, you can build libraries of narrative sections, assemble reports quickly, customise them for each engagement and export professional reports without copying content between Word documents.There's lots more you can do too..Jul 17, 2026 11:02 AM

Router ARP/NAT contradict after reload. Client ghost or firmware bug?https://news.ycombinator.com/item?id=48942957I have a Keenetic Extra DSL router. I configured a static DHCP reservation so that my ESP32-W5500 device (MAC: de:ad:be:ef:fe:01) always receives 192.168.1.114. There's a MAC-based port forwarding rule for port 80, and a defined [subdomain].keenetic.pro points to this device as well.After a soft-restart, port forwarding silently breaks for WAN traffic. The rule appears active in the panel, but incoming connections from the outside just time out.This has recurred consistently across multiple soft-reload events over several months, with a different "ghost" IP each time (.100, .101, .102).From the local network, however, I can always reach the client on its assigned static IP (.114) without any interruption. And here's the kicker: if I simply disable and re-enable the port forwarding rule from the router's interface, the problem vanishes instantly and external WAN access comes right back.The weird part: during an outage, when I look at the router's own diagnostic tools, the ARP table and Jul 17, 2026 3:06 AM

Ask HN: Best meeting transcription daemon for macOS?https://news.ycombinator.com/item?id=48936123Granola are cracking down on their auth and I can no longer pull my meeting notes out and put them in Obsidian (my plugin is gonna have to be deprecated: https://github.com/tomelliot/obsidian-granola-sync/).That means I'm gonna need a different meeting transcription/summary pipeline. There's a cambrian explosion of meeting transcription tools (https://hn.algolia.com/?q=Show+HN%3A+transcription). It's awesome.I've tried some, but haven't found one that works how I want. Can you help me find one that suits my use case?- daemon runs in the background- uses local models for transcription, diarization/speaker identification- primary interface is CLI/no UI. It should just happen in the background.- GUI is secondary. Maybe a button in the menu bar for starting/stopping a meetingoptional/secondary- pulls in calendar info for titling and attendees- cleans the transcript- generates summaryJul 16, 2026 3:44 PM

Show HN: I've built tldraw for HTML and Markdown pages (with encryption)https://pastehex.dev/Hello, HN!This is a small app I've built to satisfy three pains/wishes I've had for a while and I think there might be people out there who can benefit from it as well.1. I want to pop up a new tab, start writing my thoughts and, maybe, share them over the internet. As fast as I can and with as little friction possible. tldraw totally does this for drawing stuff in a whiteboard but for text, Obsidian is a local tool that requires installing and Notion is too involved. I want a simple link that just works the moment you navigate to the page.2. Sometimes I wanted to share code or other text artifacts with customers over Discord, but the platform caps messages to a certain length before it forces you to submit a .txt. Pastebin kinda fills this gap but it's an old site and it doesn't handle BIG pastes very well also it doesn't double as your own document vault (plus I don't care about all their "public pastes" thing).3.

Thinking: Alternate Distribution for Filmmakershttps://news.ycombinator.com/item?id=48931604This idea did not in anyway start with the intention of distribution. In my 20s there were a group of 12 of us, who shared a whatsapp group and every thursday, we had a standing appointment to decide and watch the interesting movie for the week.Over the years as life happens and folks got married, moved, priorities shifted, that ritual that almost lasted a decade fell apart.During the pandemic, given that most of us had a VR headset, we reconnected and started watching movies together - we'd setup a shared stream and would have a google chat going on the side, so that we can hear each other while the movie played.VR has been surprisingly good to recreate that theatrical atmosphere - but the worst bit is sitting in a virtual cinema as the only person. Dimming the lights out (within the virtual environment so that you don't see the empty chairs) and having a video call where we can hear each other on one of the ears, kinda felt a bit like the gang was back together.Even if it hasn't beenJul 16, 2026 8:06 AM
