Show HN: 4B+ DNS Records Dataset https://ift.tt/Tg71MtG

Show HN: 4B+ DNS Records Dataset Hi HN, I've been working on building a pipeline to create a DNS records database lately. The goal is to enable research as well as competitive landscape analysis on the internet. The dataset for now spans around 4 billion records and covers all the common DNS record types: A AAAA ANAME CAA CNAME HINFO HTTPS MX NAPTR NS PTR SOA SRV SSHFP SVCB TLSA TXT Each line in the CSV file represents a single DNS record in the following format: https://ift.tt/rvDGJdT Let me know if you have any questions or feedback! https://ift.tt/EOoV3iU October 16, 2024 at 12:56AM

Show HN: Turn any YouTube video into a summary, quiz, & flashcards https://ift.tt/hXYD2to

Show HN: Turn any YouTube video into a summary, quiz, & flashcards YouTube is the greatest learning resource in the world. Yet it doesn't provide any tools to help you learn from videos. I built a simple app that turns YouTube videos into structured learning material using AI. It generates a summary, quiz and flashcards from video content, meaning you can learn from anything (well, at least any YouTube video). Try it out. Would be happy to keep building features based on feedback! https://asterlab.io/ October 14, 2024 at 11:15PM

Show HN: Those Who Die as Cattle https://ift.tt/YGPLxTe

Show HN: Those Who Die as Cattle What if a game gave you the backstory of everyone you killed or got killed? I feel like I've heard this question asked before, but I've never seen it done. For Ludum Dare 56 (a game jam), I spent 48 hours building a prototype called Those Who Die As Cattle, a WW1 trench warfare simulation game. I used ChatGPT 4o-mini to generate details for the 12,000 soldiers involved in the game. Notably, I had to supply names because it couldn't introduce sufficient variety. I also had to add randomly generated adjectives for the soldiers; otherwise, the prompts were too similar, even with different seeds and temperatures. Initially, I used Claude (which I usually prefer), but it made every soldier a former carpenter’s apprentice. Since this is a game and your actions should matter, instead of generating one block of text, I had it generate JSON by providing a template with cues for different things that might happen to the soldier. I used these to dynamically assemble a story for each casualty. For example: { "briefBio": "Tell me a little bit about the solider", // Putting this first is critical to introduce variety … "lastThoughtsArtilleryDead": "What are his last thoughts as he dies from an artillery strike" , … "effectOnOthersShotInjured": "What are the long term impacts on the people who care about him when he is seriously injured by a bullet wound", } The prompt template can be found here: https://ift.tt/WX8Ecrd... The underlying simulation was programmed using Unity ECS (Entity Component System) and simulated, to some degree, each soldier and artillery piece. Casualties were taken in entity order, so there's some predictability regarding when each name gets added to the list, though it isn't completely deterministic. The area where I skimped the most was the UI, but the game is in a playable state if you're willing to look at the center column and figure out what the numbers mean. A final notable learning is that Unity UI toolkit (their modern, web dev like solution) performs significantly better on the web than in the native linux build, at least on the 2022 LTS version of Unity. This suggests that they may be leveraging the rendering efficiencies built into browsers. https://ift.tt/TaWZJt0 October 14, 2024 at 09:32PM

Show HN: Book to Classical Music Soundtrack https://ift.tt/UZc2J6f

Show HN: Book to Classical Music Soundtrack Hey, HN, literature and classical music are two of my biggest passions, and I always found it interesting how some classical pieces fit to the stories they are barely connected with. E.g. some of Tchaikovsky's music will always evoke the world of Harry Potter for me; music of Sibelius takes me to the same landscapes as writings of Tolkien - of course, these clearly result from John Williams' and Howard Shore's direct inspirations from the romantic composers when creating the soundtracks for the movie adaptations. For a more niche example, music of Olivier Messiaen fits in my view the book L'Écume Des Jours by Boris Vian - grandiose movements of the Turangalila symphony for the first half of the story, the expressionism and sadness of Vingt Regards the latter. The examples are numerous. My recent idea was to somehow automate this pairing of literature and music. It works quite simply - at first, I collected a large dataset of classical music pieces with text descriptions, which I transformed into embeddings. When generating a soundtrack, I use an LLM to create a description of what kind of music would be suitable for the story, and the embedding of this description is used to fetch the most relevant tracks. While the resulting playlist can barely be understood as "soundtrack" at this point, it can be a pleasant background playlist for reading the book. Thanks in advance for any suggestions or feedback :) https://ift.tt/B3PCMft October 14, 2024 at 02:58AM

Show HN: I made a git rebase TUI editor https://ift.tt/AU7FBgN

Show HN: I made a git rebase TUI editor I use interactive rebase quite often, and particularly like the editor bundled with IntelliJ. But I do not always work with IntelliJ, and am not 'fluent' with Vim, so I tried to replicate roughly the same rebase experience within a TUI. I used a small TUI OCaml project i made last year. The notable features are: - Move commits up and down, fixup, drop - Rename commits from the editor (without having to stop for a reword during the rebase run) - Visualize modified files along commits - 'Explode' a commit ,creating a commit for each modified file (a thing I found myself doing quite often) Feedbacks (both on the tool and the code) and contributions welcome, hope it could fit other people needs too ! https://ift.tt/wDL7M3J October 14, 2024 at 01:33AM

Show HN: A simple online text to SVG converter Hello! I made a simple online text to SVG converter, mainly for my own use (I was tired of launching Inkscape for such a simple task). It supports Google fonts, font size, color, line breaks, etc. It uses OpenType.js. I am a big fan of really simple tools, which do one thing and do it well. Hopefully this is one of them. I'll be happy if anyone else finds it useful. Thanks! https://text-to-svg.com October 13, 2024 at 01:34AM

Show HN: SSO – Small String Optimization https://ift.tt/FmKEYgN

Show HN: SSO – Small String Optimization I wrote this just for fun when saw article about sso in Rust[1]. My string can store up to 23 (excluding null-terminator) 8-bit chars without calling allocator. Here I can mistake, but.. Curious fact: both - libstdc++[2] and libc++[3] - do access to union member without any check that it is active now. AFAIK, this is UB in C++. But I assume that they just rely on theirs compiler features. I tried to avoid this using `std::byte[]`. But I'm still sure that there are several UB's in my code :) [1] https://ift.tt/QM1CrzF...

Show HN: ZenMD converts a Markdown folder to a site with a single command https://ift.tt/pSbThIJ

Show HN: ZenMD converts a Markdown folder to a site with a single command I have been dogfooding this npx tool to build all my markdown content sites. It allows me to start a site within minutes. As it's just `npx zenmd && netlify deploy` without downloading any framework starter kit, cloning any repo, or generating any folder structure with configs. It's built on remark.js, supports images, [[wikilinks]], and raw html in markdown, as well as custom layout.html customizations. Once the site is built, you can open the output `.html` pages without a server to preview. Demo: here is a post expanding on the "whys" on my personal site (built with ZenMD) - https://ift.tt/p8aFb4R Just made the Github repo: https://ift.tt/SADbPpx public if you'd like to look at the code. https://ift.tt/zWwhSPQ October 11, 2024 at 09:54PM

Show HN: QuickDessert – generate quick dessert recipes and adjust Ingredients https://ift.tt/Sqejytn

Show HN: QuickDessert – generate quick dessert recipes and adjust Ingredients It’s not just your average recipe site – they’ve got an AI-powered feature that generates custom dessert recipes based on your preferences or available ingredients! If you’re short on time or ingredients, the site lets you tweak recipes on the fly. You can adjust ingredients to suit your pantry, dietary preferences, or time constraints, and the AI will instantly generate a new dessert idea for you. Super handy for those moments when you have a sweet tooth but not everything in your kitchen! For example, I tried out a brownie recipe and swapped out sugar for honey – worked like a charm! The flexibility and ease make it really fun to experiment with desserts without spending hours searching for ideas or second-guessing ingredient swaps. https://ift.tt/zKLAMCF October 9, 2024 at 07:51PM

Show HN: Build Apps via Voice https://ift.tt/SwiLsq0

Show HN: Build Apps via Voice TiramAi - Beta - We have built an app that is now available both on App Store & Play Store that allows non-technical users to build web apps, mobile apps and logic apps as it seems fit by generating user stories and personas. Can be refined as many times. For web apps, the code gets generated in html, cs, JavaScript for the frontend and uses firebase as the db. For mobile app, flutter code gets generated and it takes us a day or so to get it out into test flight or beta testing, due to the app distribution hurdle. Logic apps use c# minimal api and gets deployed on Azure / Google. Exporting of User stories is behind a paywall. We are still fine tuning the code output for all the apps. You can provide feedback within the app as well by shaking the device. Any input / feedback / thoughts are appreciated. https://www.tiram.ai October 11, 2024 at 04:08AM

Show HN: Arch – an intelligent prompt gateway built on Envoy https://ift.tt/zWGhCkm

Show HN: Arch – an intelligent prompt gateway built on Envoy Hi HN! My name is Adil Hafeez, and I am the Co-Founder at Katanemo and the lead developer behind Arch - an open source project for developers to build faster, generative AI apps. Previously I worked on Envoy at Lyft. Engineered with purpose-built LLMs, Arch handles the critical but undifferentiated tasks related to the handling and processing of prompts, including detecting and rejecting jailbreak attempts, intelligently calling “backend” APIs to fulfill the user’s request represented in a prompt, routing to and offering disaster recovery between upstream LLMs, and managing the observability of prompts and LLM interactions in a centralized way - all outside business logic. Here are some additional key details of the project, * Built on top of Envoy and is written in rust. It runs alongside application servers, and uses Envoy's proven HTTP management and scalability features to handle traffic related to prompts and LLMs. * Function calling for fast agentic and RAG apps. Engineered with purpose-built fast LLMs to handle fast, cost-effective, and accurate prompt-based tasks like function/API calling, and parameter extraction from prompts. * Prompt guardrails to prevent jailbreak attempts and ensure safe user interactions without writing a single line of code. * Manages LLM calls, offering smart retries, automatic cutover, and resilient upstream connections for continuous availability. * Uses the W3C Trace Context standard to enable complete request tracing across applications, ensuring compatibility with observability tools, and provides metrics to monitor latency, token usage, and error rates, helping optimize AI application performance. This is our first release, and would love to build alongside the community. We are just getting started on reinventing what we could do at the networking layer for prompts. Do check it out on GitHub at https://ift.tt/QGs5EIO . Please leave a comment or feedback here and I will be happy to answer. (I did make a mistake earlier not properly tagging the title with Show HN and the post didn't end up in Show HN. Later I updated the title but then my text started showing up as a comment.

Show HN: VRE Dataset generation for MultiTask vision models training from videos https://ift.tt/6S8wZgq

Show HN: VRE Dataset generation for MultiTask vision models training from videos Been working on this tool for my PhD which involves training multi task vision models using various pre-trained models as inputs or pseudolabels in order to improve generalization. I work mostly on UAV datasets, but it should work okay on indoor scenes or self driving (at least Marigold and Mask2Former). For example, this dataset was generated using this tool: https://ift.tt/OLAv2p9 I'm quite aggressively trying to "just get the nn.Module" from the public repos that other researchers put up in their overly convoluted frameworks. A simple `forward(rgb_input: torch.Tensor) -> torch.Tensor` is nice, having 100 imports from a generic framework that has versions incompatibilities with everything else is not.
