Show HN: It took me 5() months to build a Plausible alternative https://ift.tt/LdzuQjD

Show HN: It took me 5() months to build a Plausible alternative After months of using Google Analytics I realized only about 50% of people accepted my cookie-popup. I had months of incorrect data for my website. I started looking for alternatives and eventually found Plausible, which is great (and open-source). Problem is, I didn't feel like paying 9$ a month to see the amount of visitors on a website i didn't even earn anything on, it was just a hobby project. Eventually I started making my own web analytics. Which actually isn't that hard. It took me about a month of working on my spare time every now and then. Being GDPR compliant basically means to not save any personal identifiers. At first I thought it would be easy since something like a public IP adress can't count as a personal identifier right? I was very wrong. How it works: When a user visited my website I saved the IP and Header for 24 hours. Then if they visited again I checked the combination of IP and Header against the ones saved in my DB. If they were the same I simply added 1 view to my data. If they weren't the same I added 1 unique daily user and 1 view. That's in short how it works. A few weeks later I realized if I had this problem then other would also have it. So I started working on Simplytics.dev. I had to do a lot of new stuff and re-build my code from the ground-up twice. Small things like OAuth was completely new to me and took up a lot of time. But eventually I got here and just launched something that with the knowledge I have today wouldn't even take a third of the time recreating today. It's my first real "Launch" and it feels really good finally creating something AND publishing it. Instead of a montly fee I opted to make it a pay-once service. Right now it's priced at 49$ but I'll see how it works out. If you got any questions on how it works Id love to answer them. November 25, 2024 at 09:05PM

Show HN: I built an extension to contact Airbnb hosts direcly https://ift.tt/rmBCMUg

Show HN: I built an extension to contact Airbnb hosts direcly Hey HN, Over the years, I’ve found myself frustrated with the extra fees Airbnb. While they provide a lot of convenience, the service fees often stack up to a point where they overshadow any potential savings. I started wondering if there was a way to connect directly with property hosts and skip the middleman entirely. That curiosity led me to build getaway.direct, a free Chrome extension that helps travelers save money. It works like this: 1. You browse listings on Airbnb. 2. The extension scans for direct booking links, host websites, or social media profiles where you can reach out to the host directly. 3. It shows those results instantly, so you can compare prices, avoid service fees, and book smarter. The main idea is to provide transparency. A lot of hosts already have their own websites but rely on platforms like Airbnb for visibility. This tool helps surface those direct options, which can often save you 10-20% per booking. I’d love to hear your thoughts: Would something like this be helpful to you? Also, I’m curious to get feedback on ways to improve the tool—whether it’s adding more integrations, improving usability, or something else entirely. Thanks for reading! Let me know what you think. https://ift.tt/KN8l15j November 29, 2024 at 04:48PM

Show HN: MyDuck Server – Supercharge MySQL and Postgres Analytics with DuckDB https://ift.tt/37V1yac

Show HN: MyDuck Server – Supercharge MySQL and Postgres Analytics with DuckDB Hello HN! We're excited to announce MyDuck Server, an open-source project that seamlessly integrates the analytical power of DuckDB with your existing MySQL & Postgres databases. *Backstory* Currently, there are no fully satisfactory open-source OLAP solutions for MySQL & Postgres. In the MySQL ecosystem, HeatWave offers close integration, but it's a proprietary, commercial product from Oracle. The Postgres community has seen promising DuckDB-based extensions emerge, including the official pg_duckdb. However, extensions can introduce isolation concerns in mission-critical environments. Consequently, many organizations resort to setting up complex and costly data movement pipelines using tools like Debezium, Flink, or other commercial solutions to replicate data from MySQL & Postgres to OLAP systems (e.g., Snowflake, BigQuery, ClickHouse) or Lakehouses (e.g., Delta Lake + Spark). This approach introduces significant operational overhead and expense. Another emerging strategy is the zero-ETL approach, increasingly advocated by cloud providers. This model simplifies data integration by allowing the cloud provider to manage ETL pipelines, while necessitating reliance on specific cloud ecosystems and services. *Key features* MyDuck Server offers a real-time analytical replica that leverages DuckDB's native columnar storage and processing capabilities. It operates as a separate server, ensuring isolation and minimizing impact on your primary database. Key features include: - Easy Zero-ETL: Built-in real-time replication from MySQL & Postgres with no complex pipelines to manage. It feels like a standard MySQL replica or Postgres standby. With the Docker image, passing a connection string is enough. - MySQL & Postgres Protocol Compatibility: We take this seriously and are working to make this project integrate well with the existing ecosystem around MySQL & Postgres. Currently, it is already possible to connect to MyDuck with standard MySQL & PostgreSQL clients in many programming languages. - HTAP Support: A standard database proxy can be deployed in front of a MySQL/Postgres primary and its MyDuck replica to route write operations to the primary and read operations to the replica. It just works. - DuckDB SQL & Columnar I/O over Postgres Protocol: It's unnecessary to restrict ourselves to MySQL/Postgres's SQL expressiveness and row-oriented data transfer. The Postgres port accepts all DuckDB-valid SQL queries, and you can retrieve query results in columnar format via `COPY (SELECT ...) TO STDOUT (FORMAT parquet/arrow)`. - Standalone Mode: It does not need to be run as a replica. It can also act as a primary server that brings DuckDB into server mode and accepts updates from multiple connections, breaking DuckDB's single-process limitation. *Relevant Previous HN Threads* - pg_duckdb [1] ( https://ift.tt/NUsgpEu ) is the official Postgres extension for DuckDB. It uses DuckDB as an execution engine to accelerate analytical queries by scanning Postgres tables directly. - pg_mooncake [2] ( https://ift.tt/28IdYFM ) is a Postgres extension that adds columnstore tables for PG. It uses pg_duckdb under the hood but stores data in Lakehouse formats (Iceberg & Delta Lake). - BemiDB [3] ( https://ift.tt/le8GF4Z ) is also a DuckDB-based Postgres replica. Unlike us, they focus on storing data in Lakehouse format. We believe MyDuck Server offers a compelling solution for those seeking high-performance analytics on their MySQL & Postgres data without the complexities and costs of traditional approaches. We're eager to hear your feedback and answer any questions you might have. Let me know what you think!

Show HN: A website to practice for job interviews https://ift.tt/RsmrjJE

Show HN: A website to practice for job interviews A little backstory- When I first arrived in Canada as an international student, I met a guy who created a product called InterviewPal. I was fascinated and eager to use it, but soon discovered it was exclusive to University of Alberta students. This made me frustrated so I decided to take on the challenge of building a better alternative- something more accessible and affordable. After I announced Zilta’s waitlist on LinkedIn, Aryan blocked me, which bummed me out for a bit. But it only fueled my drive to create something much better than his overpriced product. My goal was to offer a solution that students and recent grads could actually afford and benefit from. And that’s how Zilta came into existance. I also wanted to give indie hacking a shot and took this endeavor so you can say I hit two birds with one stone haha --- Zilta was launched in June but I wasn't able to work on it extensively because of the workload from college and a part-time job I do. Now that the semester is approaching its end, I'm getting more time for it. Frankly speaking, I don't really know where to take this product to. Right now I am a little confused if I should focuss on marketing and getting more users to try it out and then add more features to it or the opposite. On the other hand, I've also listed this startup to sell for a few bucks because marketing is so hard. What I want deep down? I want this product to grow to 1-2K MRR and then sell it. The problem? I am not sure if I'm heading in the right direction. I'd like you all to give it a try and roast this product. I'm open to receving constructive critism and any advice that can help me succeed in this journey. Should I work on marketing, adding more features or selling this? https://www.zilta.io/ November 27, 2024 at 11:54PM

Show HN: Video Composition Tool Powered by Qwen2.5-Coder and FFmpeg This tool allows you to drag and drop your own assets, such as videos, audio, and images, and then use natural language instructions to generate a new video. It uses the Qwen2.5-Coder-32B-Instruct model to process your assets and instructions, to generate a valid FFMPEG command. This command is then executed on your assets to create the desired video. What's particularly exciting with this is that it's powered by an open-source model licensed under Apache 2.0 ( https://ift.tt/Blkf4KF ).

Show HN: Open-Source Pull Request AI Reviewer https://ift.tt/xhb5Ayk

Show HN: Open-Source Pull Request AI Reviewer Hey HN, Over the last year, I’ve reviewed more than 1000 code changes. Most of the time was spent catching obvious mistakes rather than debating complex design decisions. If we estimate ~10 minutes per review, that’s 160+ hours spent reviewing code in just one year. So I thought: could I get some of that time back using LLMs? That's why I spent the last few weekends building Presubmit.ai, an open-source AI reviewer that runs as a Github Action right when you open a Pull Request. The results so far are promising: I estimate it can reduce the review time by 50%, which in my case would mean I save 80hours (~10 working days) per year. Unlike similar SaaS solutions, the goal is not to replace the human reviewer but to highlight obvious mistakes early, spot security vulnerabilities and give more context about the change. I like to think of it as a “pre-reviewer”. Some of its features are: * Line-by-line comments * PR summarization * Title generation on request * Responds to review comments It supports all major LLMs, but I’ve found Anthropic's Claude works best for this use case. Please give it a try and share your feedback! https://ift.tt/vNMh8Ug https://ift.tt/vNMh8Ug November 22, 2024 at 08:28PM

Show HN: VS Code extensions that display CGM blood glucose levels in status bar https://ift.tt/9yaw3rd

Show HN: VS Code extensions that display CGM blood glucose levels in status bar As a Type 1 diabetic, I need to continuously monitor my blood glucose levels. I’ve implemented a couple of Visual Studio Code extensions that retrieve the latest blood glucose readings from your CGM and display them in your VS Code status bar. One VS code extension uses the Nightscout CGM to retrieve the blood glucose readings. It requires users to run the Nightscout application on a hosted server. A nice benefit of Nightscout application is that it works with all the major CGM devices. However, a slight drawback of this option is that it requires a hosted third party software (Nightscout) for proper functionality. I’ve also implemented a Visual Studio code extension for those (like myself) that use the Freestyle Libre CGM. This version connects directly to LibreLinkUp to retrieve the latest blood glucose readings and display them in your VS code status bar. This removes the dependency for the intermediary Nightscout application. If you are or know any software engineers living with diabetes, these tools might be helpful with diabetes management. These are tools I built for myself that help me manage my diabetes. They are completely free and open source. I am not selling anything. Users of the tools can use them without any restrictions or connection to me. I am genuinely trying to help others in the community that are software engineers and might find this helpful. If you try out any of these extensions, I’d love to hear back from you. Any feedback on improvements are very welcome and appreciated. - https://ift.tt/t3AqbBZ... - https://ift.tt/IVmTXiM...

Show HN: Autotab – Programmable AI browser for turning web tasks into APIs https://ift.tt/0mJye2M

Show HN: Autotab – Programmable AI browser for turning web tasks into APIs Hey HN, we're Alexi and Jonas the co-founders of Autotab ( https://autotab.com ). Autotab is a chrome-based browser you can teach to do complex tasks, with a simple API for running them from your app or backend. Here is a walkthrough of how it works: https://youtu.be/63co74JHy1k , and you can try it for free at https://autotab.com by downloading the app. Why a dedicated editor? The number one blocker we've found in building more flexible, agentic automations is performance quality BY FAR ( https://ift.tt/z61iD7R... ). For all the talk of cost, latency, and safety, the fact is most people are still just struggling to get agents to work. The keys to solving reliability are better models, yes, but also intent specification. Even humans don't zero-shot these tasks from a prompt. They need to be shown how to perform them, and then refined with question-asking + feedback over time. It is also quite difficult to formulate complete requirements on the spot from memory. The editor makes it easy to build the specification up as you step through your workflow, while generating successful task trajectories for the model. This is the only way we've been able to get the reliability we need for production use cases. But why build a browser? Autotab started as a Chrome extension (with a Show HN post! https://ift.tt/iyrKI7p ). As we iterated with users, we realized that we needed to focus on creating the control surface for intent specification, and that being stuck in a chrome sidepanel wasn't going to work. We also knew that we needed a level of control for the model that we couldn't get without owning the browser. In Autotab, the browser becomes a canvas on which the user and the model are taking turns showing and explaining the task. Key features: 1. Self-healing automations that don't break when sites change 2. Dedicated authoring tool that builds memory for the model while defining steps for the automation 3. Control flows and deep configurability to keep automations on track, even when navigating complex reasoning tasks 4. Works with any website (no site-specific APIs needed) 5. Runs securely in the cloud or locally 6. Simple REST API + client libraries for Python, Node We'd love to get any early feedback from the HN community, ideas for where you'd like the product to go, or experiences in this space. We will be in the comments for the next few hours to respond! November 21, 2024 at 01:52AM

Show HN: Weave - actually measure engineering productivity https://ift.tt/oTFhlpa

Show HN: Weave - actually measure engineering productivity Hey HN, We’re building Weave: an ML-powered tool to measure engineering output, that actually understands engineering output! Why? Here’s the thing: almost every eng leader already measures output - either openly or behind closed doors. But they rely on metrics like lines of code (correlation with effort: ~0.3), number of PRs, or story points (slightly better at ~0.35). These metrics are, frankly, terrible proxies for productivity. We’ve developed a custom model that analyzes code and its impact directly, with a far better 0.94 correlation. The result? A standardized engineering output metric that doesn’t reward vanity. Even better, you can benchmark your team’s output against peers while keeping everything private. Although this one metric is much better than anything else out there, of course it still doesn't tell the whole story. In the future, we’ll build more metrics that go deeper into things like code quality and technical leadership. And we'll build actionable suggestions on top of all of it to help teams improve and track progress. After testing with several startups, the feedback has been fantastic, so we’re opening it up today. Connect your GitHub and see what Weave can tell you: https://ift.tt/cnELadm . I’ll be around all day to chat, answer questions, or take a beating. Fire away! https://ift.tt/cnELadm November 20, 2024 at 11:13PM

I wonder when more computers will have them built in. - I added a CSP to the iframe only because I was worried about spamming sites since I update the iframe anytime a new token comes in. So if you have an image on the page it will get reloaded every time the iframe is updated. Otherwise there would be no reason for it. https://ift.tt/H6mZ2PJ November 20, 2024 at 01:54AM

Show HN: archgw: open-source, intelligent proxy for AI agents, built on Envoy https://ift.tt/U0sTV67

Show HN: archgw: open-source, intelligent proxy for AI agents, built on Envoy Hi HN! This is Adil, Salman, Co and Shuguang and we're excited to introduce archgw [1], an open source intelligent proxy for agents built on Envoy [2]. Arch moves the critical but crufty work around safety, observability, and routing of prompts outside business logic. Arch is a uniquely intelligent infrastructure primitive, engineered with purpose-built fast LLMs [3] for tasks like intent detection over multi-turn, parameter identification and extraction, triggering single/multiple function calls, and offers convenience features to auto dispatch LLM calls for summarization based on data from your APIs via system prompts configured in archgw. Today, the approach to build a smart production-ready agent is weaving together a large set of mono-functional opinionated libraries, adding extra layers like LLM-based preprocessing to determine things like relevance and safety of the user's prompt (e.g. applying governance and guardrails). Once past that stage, developers must extract relevant information from the user prompt to determine intent, extract parameters as necessary, package relevant tools calls to an LLM to trigger a backend API to execute particular domain-specific task. etc. After all that is done then only are developers ready to trigger an LLM call for summarization and must manage upstream error handling and retry logic themselves. Not to mention, if they want to experiment with multiple LLMs or move between LLM versions, they have to write crufty undifferentiated code. This entire experience is slow, error prone, cumbersome, and not specifically unique. Prior to building archgw, the team spent time building Envoy [2] at Lyft, API Gateway at AWS, specialized search and intent models at Microsoft Research and worked on safety at Meta. archgw was born out of the belief that several rules based mono-functional tools should be converged into a multi-functional infrastructure primitive designed for prompts and agents. We built archgw on the highly popular, battle-tested open source proxy Envoy and re-imagined it for prompts and agents. For this we had to build blazing fast LLMs [3] that can handle crufty, ahead-in-the-request-path type of work in handling and processing prompts that are sent to an agent, so that developers can focus on what matters most: building fast personalized agents without the unnecessary prompt engineering and systems integration work needed to get there. Here are some additional details about the open source project. arghw is written in rust, and the request path has three main parts: * Listener subsystem which handles downstream (ingress) and upstream (egress) request processing. * Prompt handler subsystem. This is where archgw makes decisions on the safety of the incoming request via its prompt_guard primitive and identifies where to forward the conversation to via its prompt_target primitive. * Model serving subsystem is the interface that hosts all the lightweight LLMs engineered in archgw and offers a framework for things like hallucination detection of our these models We loved building this open source project, and our belief is that this infra primitive would help developers build faster, safer and more personalized agents without all the manual prompt engineering and systems integration work needed to get there. We hope to invite other developers to use and improve Arch. Please give it a shot and leave feedback here, or at our discord channel [4] Also here is a quick demo of the project in action [5]. You can check out our public docs here at [6]. Our models are also available here [7]. [1] https://ift.tt/JqozSv9 [2] https://ift.tt/Wo0VJPR [3] https://ift.tt/4TInQR8...

Show HN: FastGraphRAG – Better RAG using good old PageRank https://ift.tt/0MTG5Uk

Show HN: FastGraphRAG – Better RAG using good old PageRank Hey there HN! We’re Antonio, Luca, and Yuhang, and we’re excited to introduce Fast GraphRAG, an open-source RAG approach that leverages knowledge graphs and the 25 years old PageRank for better information retrieval and reasoning. Building a good RAG pipeline these days takes a lot of manual optimizations. Most engineers intuitively start from naive RAG: throw everything in a vector database and hope that semantic search is powerful enough. This can work for use cases where accuracy isn’t too important and hallucinations are tolerable, but it doesn’t work for more difficult queries that involve multi-hop reasoning or more advanced domain understanding. Also, it’s impossible to debug it. To address these limitations, many engineers find themselves adding extra layers like agent-based preprocessing, custom embeddings, reranking mechanisms, and hybrid search strategies. Much like the early days of machine learning when we manually crafted feature vectors to squeeze out marginal gains, building an effective RAG system often becomes an exercise in crafting engineering “hacks.” Earlier this year, Microsoft seeded the idea of using Knowledge Graphs for RAG and published GraphRAG - i.e. RAG with Knowledge Graphs. We believe that there is an incredible potential in this idea, but existing implementations are naive in the way they create and explore the graph. That’s why we developed Fast GraphRAG with a new algorithmic approach using good old PageRank. There are two main challenges when building a reliable RAG system: (1) Data Noise: Real-world data is often messy. Customer support tickets, chat logs, and other conversational data can include a lot of irrelevant information. If you push noisy data into a vector database, you’re likely to get noisy results. (2) Domain Specialization: For complex use cases, a RAG system must understand the domain-specific context. This requires creating representations that capture not just the words but the deeper relationships and structures within the data. Our solution builds on these insights by incorporating knowledge graphs into the RAG pipeline. Knowledge graphs store entities and their relationships, and can help structure data in a way that enables more accurate and context-aware information retrieval. 12 years ago Google announced the knowledge graph we all know about [1]. It was a pioneering move. Now we have LLMs, meaning that people can finally do RAG on their own data with tools that can be as powerful as Google’s original idea. Before we built this, Antonio was at Amazon, while Luca and Yuhang were finishing their PhDs at Oxford. We had been thinking about this problem for years and we always loved the parallel between pagerank and the human memory [2]. We believe that searching for memories is incredibly similar to searching the web. Here’s how it works: - Entity and Relationship Extraction: Fast GraphRAG uses LLMs to extract entities and their relationships from your data and stores them in a graph format [3]. - Query Processing: When you make a query, Fast GraphRAG starts by finding the most relevant entities using vector search, then runs a personalized PageRank algorithm to determine the most important “memories” or pieces of information related to the query [4]. - Incremental Updates: Unlike other graph-based RAG systems, Fast GraphRAG natively supports incremental data insertions. This means you can continuously add new data without reprocessing the entire graph. - Faster: These design choices make our algorithm faster and more affordable to run than other graph-based RAG systems because we eliminate the need for communities and clustering. Suppose you’re analyzing a book and want to focus on character interactions, locations, and significant events: from fast_graphrag import GraphRAG DOMAIN = "Analyze this story and identify the characters. Focus on how they interact with each other, the locations they explore, and their relationships." EXAMPLE_QUERIES = [ "What is the significance of Christmas Eve in A Christmas Carol?", "How does the setting of Victorian London contribute to the story's themes?", "Describe the chain of events that leads to Scrooge's transformation.", "How does Dickens use the different spirits (Past, Present, and Future) to guide Scrooge?", "Why does Dickens choose to divide the story into \"staves\" rather than chapters?" ] ENTITY_TYPES = ["Character", "Animal", "Place", "Object", "Activity", "Event"] grag = GraphRAG( working_dir="./book_example", domain=DOMAIN, example_queries="\n".join(EXAMPLE_QUERIES), entity_types=ENTITY_TYPES ) with open("./book.txt") as f: grag.insert(f.read()) print(grag.query("Who is Scrooge?").response) This code creates a domain-specific knowledge graph based on your data, example queries, and specified entity types. Then you can query it in plain English while it automatically handles all the data fetching, entity extractions, co-reference resolutions, memory elections, etc. When you add new data, locking and checkpointing is handled for you as well. This is the kind of infrastructure that GenAI apps need to handle large-scale real-world data. Our goal is to give you this infrastructure so that you can focus on what’s important: building great apps for your users without having to care about manually engineering a retrieval pipeline. In the managed service, we also have a suite of UI tools for you to explore and debug your knowledge graph. We have a free hosted solution with up to 100 monthly requests. When you’re ready to grow, we have paid plans that scale with you. And of course you can self host our open-source engine.

After a couple of months of work, I'm proud to share with you Peony - a first preview into what we believe will be the future of file sharing. In addition to the analytics and security features you'd expect coming from DocSend, we built Peony to be flexible and adaptable across all your file sharing needs and give you the ability to deeply personalize your file share per recipient.

Show HN: RL Agent that can auto-optimize your LLM prompts Hey everyone! Along with my team, I've developed a reinforcement learning system that automatically optimizes LLM prompts, complete with a visualization feature to track both prompt structure and learning progress over time. Take a look here: https://ift.tt/ziSRNAT... Check out our website too: https://ift.tt/uzB0Yvt In terms of how this visualization works: The RL Prompt Optimizer employs a reinforcement learning framework to iteratively improve prompts used for language model evaluations. At each episode, the agent selects an action to modify the current prompt based on the state representation, which encodes features of the prompt. The agent receives rewards based on a multi-metric evaluation of the model's responses, encouraging the development of prompts that elicit high-quality answers.

Statewide ‘Daylighting Law’ Warnings Begin Nov. 11, 2024

Statewide ‘Daylighting Law’ Warnings Begin Nov. 11, 2024
By Madhu Unnikrishnan

Parking this close to an intersection could soon get you a warning. Next year, you could face a fine. On Nov. 11, 2024, we will begin issuing written warnings for vehicles parked within 20 feet of any crosswalk in the direction of approaching traffic. For example, you could receive a warning if you park less than 20 feet in front of a stop sign. We’re doing this to comply with the statewide “Daylighting Law” (Assembly Bill 413). It went into effect at the beginning of 2024. Starting Jan. 1, 2025, we will begin issuing citations to comply with California law. Fines will start at $40. This law...

Show HN: Samsar One Version One is now live https://ift.tt/zbof9mS

Show HN: Samsar One Version One is now live Hi all, 6 months ago I started building out an app which combines all the SoTA gen-ai models out there into one platform which anyone could use to create 2-4 min long videos starting from scratch, starting from an idea. I received a ton of feedback from HN community & others along the way. Today excited to announce version one of app.samsar.one, a platform which allows anyone to easily and consistently create long, coherent and consistent generative-ai videos while picking and choosing their model starting from merely an idea. https://app.samsar.one/ October 31, 2024 at 03:36PM

Show HN: NewsCatcher's Hyperlocal News API – Granular City-Level News Feeds https://ift.tt/Dk6CAVE

Show HN: NewsCatcher's Hyperlocal News API – Granular City-Level News Feeds We’ve launched NewsCatcher’s Hyperlocal News API to provide city-level news feeds for market analysis, localized apps, and data analytics. Why We Built It: Aggregating hyperlocal news is complex. Local news comes from diverse sources, many covering national topics, making it hard to isolate local events like transit updates, crime, extreme weather alerts, or infrastructure projects. Searching by location alone can lead to irrelevant results, especially with city names that overlap or match common words (e.g., Orange, Lake). What It Does: Our API provides precise, location-based news by processing 185K articles daily and tagging each with its associated_town down to the town level with 92% accuracy. Covering 31,000 U.S. locations, it uses advanced NLP to accurately associate location names, even when they’re common words. It enables you to: - Access near-real-time, location-focused news feeds - Filter by topic (e.g., crime, sports), keyword, and date - Cluster articles covering similar events and topics - Get sentiment score for a headline and article body - Recognize and extract entities Key Features: - AI-powered location recognition and validation - Advanced querying with boolean operators and proximity search - Multiple town association methods for precise location matching - NLP-enriched content for deeper analysis - Articles clustering - Multi-language support - High volume data retrieval (up to 1000 articles per request) For a demo, try our 15 public RSS feeds: https://ift.tt/gS9layV . The API provides JSON output for easy integration. Tech Specs: - RESTful, JSON-based API - API key authentication - Scalable for high-volume queries We’d appreciate any feedback or questions on use cases. November 5, 2024 at 10:27PM

Show HN: Krixik – Easily sequence small/specialized AI models (pip-installable) https://ift.tt/9ojRrL0

Show HN: Krixik – Easily sequence small/specialized AI models (pip-installable) Our initial intention was to experiment with a smartbook idea, but we couldn't find a good prototyping tool for small/specialized AI models. That rabbit hole took us through vector databases, through infra for small AI, and finally here. We’re particularly proud of the accessibility/simplicity of our code syntax. Krixik’s model library is limited to eleven model types (modules) and a few dozen models, but we will significantly expand it. Other enhancements, like a local client and several 3rd-party integrations, are also planned. You require API credentials to try Krixik. You can quickly get them through this form: https://ift.tt/rNo79Oq And here’s a demo video (our YouTube channel also has a couple dozen example videos in it): https://youtu.be/WpSSYLfvfdM https://ift.tt/35PVnRo November 4, 2024 at 08:33PM

Show HN: Autotab Instruct – Claude Computer Use with Guardrails for Reliability https://ift.tt/x18f9nr

Show HN: Autotab Instruct – Claude Computer Use with Guardrails for Reliability Hi HN, We’ve built a desktop app to create highly reliable AI agents that use a computer with mouse and keyboard. Until last week, we had tried many different approaches to open-ended agentic features but none of them had met our reliability bar. With Anthropic’s Computer Use this finally changed, and we just shipped a feature we’re calling Instruct. Instruct allows users to create agentic blocks as part of a larger Autotab skill that provides the structured logical flow to keep the automation on track. If you haven’t had a chance to try Computer Use yet, it is an impressive leap from the last generation of vision models (e.g. gpt4o struggles with relative positions, let alone coordinates). At the same time, it is still not good enough to be given a prompt and let loose. One of the big surprises to us early on was just how much intent specification is required for most real world workflows to run reliably. What looks at first like a simple form filling task usually turns out to have dozens of edge cases and super specific, hidden rules. Even human employees need to be shown how to perform these tasks, and then refined with question-asking + feedback over time. We wanted to build a tool for specifying intent, and iterating with the model to make it reliable enough for real work. - Automations run on top of an action scaffold, which works kind of like a very fuzzy programming language with strict types. This gives the model a high level plan that guides execution, and makes it easy to break out discrete steps to get the reliability you need. (Interestingly, this has also proven useful not just for the agent, but also for the human trying to create, verify and edit the automation.) - When the model is unsure it asks for clarification. For example, if you are in editing mode and the model thinks that an element looks meaningfully different than before, it will ask you to verify that it is the same element. - The agent has access to a memory system that lets it recall information from past runs as well as instructions and feedback from the user. Here's a short video of Autotab Instruct in action: https://ift.tt/hImULow?... . There are a few more demos at https://twitter.com/autotabai/status/1852393973165199425 a75f06f82cab521bc78672ed35d85e8a. We’d love to hear what you think! November 1, 2024 at 10:26PM

Show HN: Shimmer – ADHD-adapted body doubling https://ift.tt/gbRhVqO

Show HN: Shimmer – ADHD-adapted body doubling I’m Chris, one of the co-founders of Shimmer. In 2022, following my ADHD diagnosis, I launched Shimmer ( https://shimmer.care ), a 1:1 ADHD Coaching for adults (HN launch here: https://ift.tt/OEn7vfj ). One problem we discovered while running 1:1 coaching is that people weren’t able to actually follow through (in real life) on the ideas they came up with during their weekly sessions with their coach. There is a concept called body doubling that’s popular within the ADHD community—it’s basically getting things done in the presence of other people. The positive accountability is proven to work. However, our members told us they tried other body doubling solutions or attempted to organize it themselves in real life but none of the solutions stuck. So we reverse engineered productive moments our members described, paired with scientific backing of what motivates ADHD-ers, and designed an online body doubling experience for our coaching members that provides a safe but productive space for them to get things done between weekly sessions. A few of the motivators we infused into the traditional body doubling experience were 1) newness/novelty — each session has a different guided experience in the break like breathwork or stretching, 2) urgency — there’s a large visible pomodoro timer on the top left that counts down from 25 min, 3) community — the shared space is ADHD-friendly, and has a mood check-in & sharing functionality built in so you don’t feel alone, 4) accountability — there’s a task list where each time you check something off, it notifies the group, and you can view others’ as well if they opt in. Here’s a video walking through the product experience: https://ift.tt/Kck3lp8 Our body doubling was created and iterated alongside thousands of people with ADHD on our coaching platform over 9+ months of building & iterating with them. We’re excited to unveil this experience. If you have ADHD (or executive functioning challenges), we’d love for you to check out coaching & body doubling and give us critical feedback. Shimmer’s pricing: $140/mo. for Essentials plan (15-min weekly sessions), $230/mo. for Standard plan (30-min weekly sessions), $345/mo. for Immersive plan (45-min weekly sessions); all plans start with an additional 25% off the first month, HSA/FSA-eligible. The reason why the price is so high is that this is not a self-guided app or SaaS tool. You’re matched with a real, credentialed coach (not AI) and since ADHD coaching is not reimbursed in the US, the price is hard for us to bring down because the largest cost component is the coach’s compensation. *We know these prices are still expensive for many people with ADHD. Here are the actions we’re taking: (1) we offer needs-based scholarships and aim to have 5% of members on them at any time, (2) we often run fully sponsored scholarships with our partners—over 60 full ride scholarships and 100 group coaching spots have been disbursed alongside Asian Mental Health Project, Government of Canada, and more, and (3) we have aligned our coaching model alongside Health & Wellness Coaching, which is expected to be reimbursed in the next years. If there are ways we can further drive down the cost, please reach out to me directly at chris@shimmer.care. https://ift.tt/WwEmaG2 October 31, 2024 at 10:57PM
