TLDR: I'm building an experimental open source/open data thing to collect good lecture recordings website: https://lectures.koljasam.com/ repo: github.com/koljapluemer/awesome-lectures Hi everyone, this submission is my attempt to contribute something to the question of how we will find, share and evaluate information in the future, in the face of the many problems that I think HN is well-aware of (slob, search engines returning SEO garbage or corporate stuff, spam, trust problems, big companies eating everything,...). I was specifically inspired by recent…

I asked an HN member for feedback and she blew my mind2010 · slideshare.net · ▲453A few days ago, I responded to a comment by bloggergirl offering to read anyone's web copy and help. I shot off an email hoping for a paragraph or two of feedback on my startup's copy. Instead I received a professional, detailed deck of tons of invaluable well thought out feedback. It must have taken her an entire afternoon. Here's a link to it: http://www.slideshare.net/shereefb/recommendations-for-bettermeans To top it off, this isn't someone with a lot of free time on her hands, she's only days away from launching her own startup (page99test) This community blows my mind!

Hey guys, I love HN! I wanted to extend the same aesthetic and community towards things beyond tech-related news. I thought it would be cool to get the same quality of community gathered around the latest and greatest research coming out. Let me know what you guys think of what I have so far. It's still early so there are probably bugs and other quality issues. If there's any features missing that you'd want let me know. ALSO, if any of you are familiar with the map of the territory of any particular field, please let me know! Would love to pick your brain and to come up with a 'most…

Zsync, a Reddit Alternative with the Goal to Reward Quality Comments2023 · zsync.xyz · ▲207I built this last year but never posted it anywhere, but now with Reddit hiatus it seems like the right time to give it a shot. The main goal of zsync is to foster high quality content and discussion. That's it. If it can't accomplish that, then to me it is a failure. I watched Reddit go from having high quality discussion in 2008-9 to devolving into the PC meme dumpster it is today [1]. HN still has the highest discussion quality of any "forum" I know of, but (1) it can sometimes randomly be very hostile/toxic to new tech, the most glaring example being crypto. (2) HN is basically a…

Hi HN, I spent a few weeks looking at the top HN posts of all time. This included exploration, clustering, creating visualizations, and zooming in on what (to me personally) seems like some of the best discussions on here. Three things in this post: 1- The interesting groups of HN posts 2- The interactive visualizations that you can explore in your browser 3- The data from this exploration -- this includes CSV of the titles as well as the text embeddings of 3,000 Ask HN articles. Blog post about this whole process here: [1] ============ 1- The interesting groups of HN posts From the…

Talanoa▲346Hi HN, I’m a fullstack developer, and honestly, I’ve lost count of how many side projects I’ve worked on over the years. But one idea kept coming back to me: a different kind of email client. It first came to me in 2014: “What if we could handle emails more like conversations?” Every year, I’d revisit this concept in my “Build Notes.” Ten years later, no one had built exactly what I had in mind — so I finally decided to do it myself. That’s how Talanoa was born. I wanted something focused on people, not timelines. I was tired of marking messages as unread just to remember to reply later, or…

With social media and now AI, its important to keep the indie web alive. There are many people who write frequently. Blogosphere tries to highlight them by fetching the recent posts from personal blogs across many categories. There are two versions: Minimal (HN-inspired, fast, static): https://text.blogosphere.app/ Non-minimal: https://blogosphere.app/ If you don't find your blog (or your favorite ones), please add them. I will review and approve it.
