I had the opportunity to present Securday at Defcon 31, where it received an overwhelmingly positive response. One of the most fascinating aspects I discovered during the presentation was the system's remarkable capabilities. For…

    Using stylometry to find HN users with alternate accounts2022 · stylometry.net · ▲676

    Author here. This site lets you put in a username and get the users with the most similar writing style to that user. It confirmed several users who I suspected were alts and after informally asking around has identified abandoned accounts of people I know from many years ago. I made this site mostly to show how easy this is and how it can erode online privacy. If some guy with a little bit of Python, and $8 to rent a decent dedicated server for a day can make this, imagine what a company with millions of dollars and a couple dozen PhD linguists could do. Here's Paul Graham:…

    http://www.securly.com To keep kids safe online, we felt it wasn’t enough anymore to rely simply on blocking websites (domain filtering). We also need to protect them on trusted social media sites like Facebook, YouTube and Wikipedia. We couldn’t find any solution that does this for the entire home network. We are two security hackers who have worked in the enterprise firewall space for several years and felt this was an important problem to solve. The video on our front page gives you a pretty good idea of what we do. You can also use us as a free premium DNS server by pointing your DNS to…

    I made this as a pair programming exercise with o1-preview. o1 did most of the heavy lifting, through high level prompts, but eventually I needed to diverge from it to get to completion. My initial prompt was: --- I'm making a web app: It's like 4chan, but each thread starts with a gps coordinate. People can only post text and images. I want to build it with flask and sqlalchemy. I want just the backend and data model that supports these threads, anonymous users, and users that can register a permanent username. Write as much of it as you can for me. --- This produced a fully scaffolded…

  • Hi HN, I’m Kashish, one of the co-founders of SpeedVitals, a platform for testing & monitoring website performance with a major emphasis on Core Web Vitals. Until now, our platform has only focused on Synthetic/Lab testing, such as Lighthouse tests and TTFB tests. But now, we have developed a Real-User Monitoring platform that doubles up as a Web Analytics tool. One major feature we have that most RUM tools lack is Performance Audits. Just like Lighthouse audits work on Lab test data, our audits work across all the real-user visits and gives suggestions on what task to prioritize first.…
