Show HN: Track whether cryptocurrencies are being used and for what Hey HN, I'm Jake, and I created Chainspy, a website that aggregates and visualizes on-chain metrics across multiple blockchains like Bitcoin, Ethereum, and others. It's designed to give you insights beyond just price data. Why Chainspy? - On-Chain Metrics: Track blockchain activity (e.g., transactions, active users) across multiple networks, all in one place. - Advanced Charting: Visualize blockchain data with integrated TradingView charts. Ideal for comparing blockchain performance over time. - Wealth Distribution: See how wealth is distributed across wallets and spot centralization trends. - API Access (Coming Soon): Need blockchain data for your projects? We're working on an API—let me know if you're interested! A Sneak Peek: Wealth Distribution: How is wealth spread across wallets? https://ift.tt/RVwpOis https://ift.tt/3Gu5vig Active Transactions: Which chains are seeing the most activity? https://ift.tt/iz60bSV Active Users (addresses): How many people are using the network? https://ift.tt/eD6FZcA I’m just starting out and would love feedback on features and data you'd like to see. If you have a favorite blockchain or metric you'd want tracked, let me know—I’ll try to add it. Let’s make blockchain data easier for everyone to access. https://ift.tt/lpPUKMC September 7, 2024 at 06:01AM

Show HN: Museum Music – generate period-appropriate playlists from artwork https://ift.tt/yJpgl0m

Show HN: Museum Music – generate period-appropriate playlists from artwork This is Museum Music, an app to help experience art with era-appropriate music - photograph an art piece, and it will create a unique Spotify playlist that complements its era and style. We built this from our own experiences visiting museums and thoughts of enhancing the experience with music. It's built with GPT Vision and the Spotify API. Although the initial focus was on art-inspired music, it works surprisingly well on other, day-to-day photos too! https://ift.tt/gWlbHRB September 7, 2024 at 01:52AM

Show HN: PlaceholderJS – Simple and Lightweight Placeholders https://ift.tt/pVsYtza

Show HN: PlaceholderJS – Simple and Lightweight Placeholders Hey all! My name is Owen, I'm the developer behind PlaceholderJS. Since the demise of placeholder.com, I wanted to be able to use placeholders on my React projects via a package so that way I don't have to worry about these services shutting down again in the future. Additionally, for our non-React developers out there, I created a simple CDN that functions similarly via the PlaceholderJS.com domain. In the future, I'd like to add support for more frameworks, placeholder text, additional customization, etc. I'm looking to improve this and continue to support it and would love your feedback. https://ift.tt/4LQR52k September 6, 2024 at 02:31AM

Show HN: Nomadic – Minimize RAG Hallucinations with 1 Hyperparameter Experiment https://ift.tt/2NEk9zW

Show HN: Nomadic – Minimize RAG Hallucinations with 1 Hyperparameter Experiment Hey HN! Mustafa, Lizzie, and Varun here from NomadicML ( https://nomadicml.com ). We’re excited to show you Nomadic ( https://ift.tt/sjNYO01 ): a platform focused on parameter search to continuously optimize AI systems. Here’s a simple demo notebook where you get the best-performing, statistically significant configurations for your RAG — and improve hallucination metrics by 4X in just 5 minutes — with a single Nomadic experiment: https://ift.tt/GjLSgsr Our lightweight library is now live on PyPI (`pip install nomadic`). Try one of the README examples :) Input your model, define an evaluation metric, specify the dataset, and choose which parameters to test. Nomadic emerged from our frustration with existing HPO (hyperparameter optimization) solutions. We heard over and over that for the sake of deploying fast, folks resort to setting HPs through a single, expensive grid search or better yet, intuition-based “vibes”. From fine-tuning to inference, small tweaks to HPs can have a huge impact on performance. We wanted a tool to make that “drunken wander” systematic, quick, and interpretable. So we started building Nomadic - our goal is to create the best parameter search platform out there for your ML systems to keep your hyperparameters, prompts, and all aspects of your AI system production-grade. We started aggregating top parameter search techniques from popular tools and research (Bayesian Optimizations, cost-frugal flavors). Among us: Built Lyft’s driver earnings platform, automated Snowflake’s just-in-time compute resource allocation, became a finalist for the INFORMS Wagner Prize (top prize in industrial optimization), and developed a fintech fraud screening system for half a million consumers. You might say we love optimization. If you’re building AI agents / applications across LLM safety, fintech, support, or especially compound AI systems (multiple components > monolithic models), and want to deeply understand your ML system’s best levers to boost performance as it scales - get in touch. Nomadic is being actively developed. Up next: Supporting text-to-SQL pipelines (TAG) and a Workspace UI (preview it at https://ift.tt/8oaYQ5b ). We’re eager to hear honest feedback, likes, dislikes, feature requests, you name it. If you’re also a optimization junkie, we’d love for you to join our community here https://ift.tt/tzENfJr September 5, 2024 at 11:44PM

Show HN: DevMuse – App to bond over music and code https://ift.tt/Dm17sPZ

Show HN: DevMuse – App to bond over music and code I've found there's a disconnect devs can feel when they are remote only, and one of the ways people have connected since the beginning of humanity has been through music. So I thought it would be interesting to build off these concepts and build a tool that brings a sense of connection to devs across the world. I don't have it fully working just yet. Still have some kinks to work out. What do you think? https://ift.tt/UKbLAif September 6, 2024 at 01:39AM

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 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 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.

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).
