Show HN: Laminar – Open-Source DataDog + PostHog for LLM Apps, Built in Rust https://ift.tt/zSUkMBw

Show HN: Laminar – Open-Source DataDog + PostHog for LLM Apps, Built in Rust Hey HN, we’re Robert, Din and Temirlan from Laminar ( https://www.lmnr.ai ), an open-source observability and analytics platform for complex LLM apps. It’s designed to be fast, reliable, and scalable. The stack is RabbitMQ for message queues, Postgres for storage, Clickhouse for analytics, Qdrant for semantic search - all powered by Rust. How is Laminar different from the swarm of other “LLM observability” platforms? On the observability part, we’re focused on handling full execution traces, not just LLM calls. We built a Rust ingestor for OpenTelemetry (Otel) spans with GenAI semantic conventions. As LLM apps get more complex (think Agents with hundreds of LLM and function calls, or complex RAG pipelines), full tracing is critical. With Otel spans, we can: 1. Cover the entire execution trace. 2. Keep the platform future-proof 3. Leverage an amazing OpenLLMetry ( https://ift.tt/1ynHjf5 ), open-source package for span production. The key difference is that we tie text analytics directly to execution traces. Rich text data makes LLM traces unique, so we let you track “semantic metrics” (like what your AI agent is actually saying) and connect those metrics to where they happen in the trace. If you want to know if your AI drive-through agent made an upsell, you can design an LLM extraction pipeline in our builder (more on it later), host it on Laminar, and handle everything from event requests to output logging. Processing requests simply come as events in the Otel span. We think it’s a win to separate core app logic from LLM event processing. Most devs don’t want to manage background queues for LLM analytics processing but still want insights into how their Agents or RAGs are working. Our Pipeline Builder uses graph UI where nodes are LLM and util functions, and edges showing data flow. We built a custom task execution engine with support of parallel branch executions, cycles and branches (it’s overkill for simple pipelines, but it’s extremely cool and we’ve spent a lot of time designing a robust engine). You can also call pipelines directly as API endpoints. We found them to be extremely useful for iterating on and separating LLM logic. Laminar also traces pipeline directly, which removes the overhead of sending large outputs over the network. One thing missing from all LLM observability platforms right now is an adequate search over traces. We’re attacking this problem by indexing each span in a vector DB and performing hybrid search at query time. This feature is still in beta, but we think it’s gonna be crucial part of our platform going forward. We also support evaluations. We loved the “run everything locally, send results to a server” approach from Braintrust and Weights & Biases, so we did that too: a simple SDK and nice dashboards to track everything. Evals are still early, but we’re pushing hard on them. Our goal is to make Laminar the Supabase for LLMOps - the go-to open-source comprehensive platform for all things LLMs / GenAI. In it’s current shape, Laminar is just few weeks old and developing rapidly, we’d love any feedback or for you to give Laminar a try in your LLM projects! https://ift.tt/VDt4BMh September 5, 2024 at 04:22AM

Show HN: Local Bookmark Storage and Archive https://ift.tt/aS1KwUQ

Show HN: Local Bookmark Storage and Archive I decided I needed a reliable backup of my bookmarks, and an archive of those pages for future reference in case they get taken down. I paid for a managed online service that did this for a while, but I was unsatisfied with the archiving reliability. This is pretty much just a 200 line python script, but it does the trick, and now I don't have to worry about losing a copy of a web page that I want to refer to in the future. https://ift.tt/Ng9pZzy September 5, 2024 at 01:29AM

Show HN: ASim – generate functional mobile apps instantly on your phone https://ift.tt/b16OXeB

Show HN: ASim – generate functional mobile apps instantly on your phone Hi HN! Daniel from YC S21 here, launching a project called aSim, which lets people generate/simulate usable native apps (called Sims) instantly from your phone. Describe an app you want and aSim will generate it. Then, edit and refine it to better suit your needs. Sims are also shareable via links, and basic app functionality is also exposed through web (though mobile is much more feature complete). A couple of my favorite Sims so far: - FridgeChef, recipes from what's in your fridge: https://asim.sh/s/419 - wordle: https://asim.sh/s/412 - HIIT workout randomizer/generator: https://asim.sh/s/418 - Pomodoro timer: https://asim.sh/s/232 Would love feedback around the experience and additional functionality you'd like surfaced! https://asim.sh/ September 4, 2024 at 11:03PM

Show HN: Icebreaking AI. A free tool to help you find close friends https://ift.tt/0I9QN3i

Show HN: Icebreaking AI. A free tool to help you find close friends Hello, everyone! My name is Alex, and I'm an expat in a new country. Two years ago, I moved to Germany where I didn’t know anyone. Starting the job, I realized that becoming close friends with colleagues can be quite challenging and slow. The feeling of loneliness was gradually growing. To change that, I started attending various meetups based on my interests, hoping to make new friends. However, I often found myself answering the same generic questions that didn’t really help me understand if someone shared my values and interests. As a result, lost energy and 0 friends. SO - That’s when I began using icebreaking questions in smaller groups. Surprisingly, these questions quickly changed any conversation to a deeper, more engaging and meaningful level. I was able to identify people I genuinely connected with and started spending more time with them. BUT - preparing and using these questions was a pain. I would Google the top-100, pick a random number, and choose a question. I felt a strong need for a simple „one button“ that does everything for me. AND - After searching and not finding such a solution, I decided to build it myself. I created a vast database of questions across various topics and integrated AI to generate questions on any subject. The idea has resonated well within my communities (university and expat parties), and more people are starting to use it. I’d love to hear your stories with icebreaking questions, your experience, and your feedback so I can make the service even more useful for more people! Check it out and share your thoughts! https://ift.tt/va50RQb September 4, 2024 at 01:24AM

Show HN: I made a REST based alternative to GraphQL for PostgreSQL https://ift.tt/fmqp0jI

Show HN: I made a REST based alternative to GraphQL for PostgreSQL Hi guys! I have had a love-hate relationship with GraphQL for a while and decided to build my own tool as a side project! It's a REST-based API generator that you can use to build and deploy on top of PostgreSQL. I am currently working on a GitHub integration so you can push your API directly to GitHub and deploy on your own infrastructure. The plan is to stabilize the features by December and then to open-source it. It's completely free to use since it's in beta, and I would appreciate any feedback I can get. Thanks: kabir@querydeck.io https://querydeck.io/ September 3, 2024 at 11:15PM

Show HN: Ban 'Any updates' emails – this is super-efficient client communication https://ift.tt/WEKjTP6

Show HN: Ban 'Any updates' emails – this is super-efficient client communication Looking for 100 beta users to use RSP for free (in return for great feedback!) I've made a Monday/ Google Sheets hybrid - making it really easy to share structured data with clients, in real-time, with no extra effort from you. This eliminates clients being in the dark or sending multiple emails per task. Project management tools are usually black boxes, where the team only communicates with clients via email threads (in the plural). Instead, with RSP, you choose at the column level what data you want to share with clients and what you want them to edit and not edit, and also have a side-by-side messenger for each task. Client communication is instant, real-time, and super-efficient. https://ift.tt/oaKUqhy September 2, 2024 at 02:40PM

Show HN: Bin-graph: Visualize binary files https://ift.tt/oNjP6gJ

Show HN: Bin-graph: Visualize binary files This program provides a simple way of visualizing the different regions of a binary file. Written in C, depends only on libpng. Currently (commit 1dd42e3) it is able to generate PNG images that represent various aspects of the binary: - Grayscale: Byte values, 00..FF. - Ascii: Printability of each byte. - Entropy: Of a "block", changed with --block-size. - Histogram: Bar graph of the byte frequencies. - Bigrams: Each point is determined by a pair of bytes. - Dotplot: Measure self-similarity. Image width/height is N^2. In the future, I plan on adding an SDL version that allows the user to view a section of the file interactively (sections are currently supported with --offset-start and --offset-end).

Show HN: I'm 17 and built a startup to find or sell parking spots https://ift.tt/CJj8uRz

Show HN: I'm 17 and built a startup to find or sell parking spots Hey HN! I'm Dris, I'm 17, and for the past few months, I've been solo-developing Parkt, an app that lets you quickly reserve or sell parking spots. Parking sucks - it's expensive, hard to find, and you usually overpay or get a ticket. With Parkt, you can reserve parking in 2 taps, or list your unused space in under 5 minutes. It's now free to download on iOS (with Android coming soon)! You can also check out a demo on the site if you're interested. If you know someone who might use Parkt, sharing the app would be super helpful! Feedback is also appreciated. https://parkt.app/ September 1, 2024 at 12:23AM

Show HN: Create notes and maps that live outdoors with web and AR integration https://ift.tt/AzNc1xf

Show HN: Create notes and maps that live outdoors with web and AR integration Hey HN, We built Auglinn to make it easy for anyone to leave notes outdoors and create interactive maps, using AR. You can: - Pin notes or questions from your desktop that appear as AR notes outside, or - Leave notes or questions while exploring outside with AR, and view them later on your map via phone or desktop. My favorite feature: creating maps by dragging and dropping photos from your phone. The story? When I was a kid, my father visited Universal Studios and captured it all on video. When I went there in 2019, I found myself wondering if I was standing in the same spots he had. This curiosity triggered my interest in leaving traces on the world, and hence AR, and then Auglinn happened... It began for individuals (hobbyists, influencers, anyone), but professionals like urban planners, municipal employees, and some tour guides also loved it, so we added SaaS features later. Feedback is much appreciated. https://www.auglinn.com August 27, 2024 at 08:28PM

Show HN: Website with coding puzzles from job interviews https://ift.tt/wtoR3Vv

Show HN: Website with coding puzzles from job interviews Hi Friends! As I run another site with more general programming exercises for years - I always felt they are different from puzzles and test projects proposed at job interviews. So recently I started this new place and am slowly adding problems here. Of course the number of such challenges I encountered in interviews myself is quite limited. So if you may recollect something of the kind which could be converted to a puzzle - please, kindly share it to me (e.g. with "rodiongork" at gmail). Puzzles of algorithmic nature or system-oriented and language-specific - are all welcome. Currently I'm working to add a few postgresql exercises and executor for them. https://ca4pro.com August 30, 2024 at 07:57PM

Show HN: Genie – Add Events to Your Google Calendar from Screenshots https://ift.tt/zuY8J7e

Show HN: Genie – Add Events to Your Google Calendar from Screenshots Hi HN Josh here, I'm excited to share a small app I built called Google Calendar Genie. I created this tool out of frustration—so many websites don’t provide Google Calendar links for events! With Genie, you can simply upload your event details screenshot, and it’ll generate a Google Calendar link for you. No need to sign in to Google or download anything — just click the generated link, and voilà, the event is added to your calendar instantly! It uses an LLM on the backend to parse and generate the events (no data is stored on the app). I’d love to hear your feedback! https://www.calendargenie.xyz/ August 30, 2024 at 02:55AM
