Show HN: Launching a new home-grown embedding LLM for RAG https://bit.ly/3PWqUJt

Show HN: Launching a new home-grown embedding LLM for RAG Hi HN! Vectara is a "batteries included" retrieval augmented generation platform. You can upload your rich text documents like PDFs, HTML pages, word docs, etc, or semi-structured JSON and Vectara handles the text and metadata extraction, segmentation, vector embedding, and vector storage, and keyword storage. You can ask a question or perform a search in the UI or via our APIs and Vectara will automatically handle the vectorization, structured metadata filtering, vector+keyword retrieval, hybrid blending, and generative summarization of the results. We're focusing on building and operationalizing the complex infrastructure for vector storage, hybrid retrieval, and generative summarization so you can use fairly high-level APIs and focus on building your own applications. We know that retrieval accuracy is incredibly important for RAG: garbage in, garbage out. We've seen a lot of projects not spend enough time on really getting the retrieval model right and wasting a lot of time/money with poor outcomes. We've spent about the past 6 months working on a new embedding model named Boomerang and just released it on the Vectara platform. We've run it through standard evaluations like BEIR (though we know many models over-fit against BEIR) as well as multi-domain evaluations. We've published the details of our tests for those that really want to dive in, but the TL;DR is that Boomerang beats most/all publicly available models in many/most situations and is particularly strong at cross-lingual and multi-domain tests. We'd love any and all feedback! https://bit.ly/3PUGfdh September 28, 2023 at 04:06PM

Show HN: Backname.io – every IP address gets its own domain I was setting up tests involving DNS resolution recently, where something like 127.0.0.1.service.foo would have been tremendously useful. Back in the day, I'd have used xip.io - but sadly that service died. Well, every excuse is a good one when it comes to writing a DNS server! Backname.io joins nip.io and sslip.io in the wildcard DNS game. https://bit.ly/3EXJiuY September 28, 2023 at 04:27PM

Show HN: RFSH – A Free-forever flows running tool https://bit.ly/3REtNjo

Show HN: RFSH – A Free-forever flows running tool At the first point of view, I want to create a tool which can help our team run the bash script easier, faster, safer, with clearly reports, so I build RFSH. To me, the first ability of good software is privacy matter. I want to create a good software and I don't want to make rich by charging on things running on your own resources (your computer, your server, your cloud,...). So basically, RFSH will be free-forever for usage. You put a .csv file, a bash script as a template file, RFSH will take care the rest, then you will receive the clearly reports after all. Things happen on your machine, safe and sound. https://bit.ly/3RCkujG September 28, 2023 at 04:32AM

Show HN: Using LLMs and Embeddings to classify application errors https://bit.ly/3PVG0yW

Show HN: Using LLMs and Embeddings to classify application errors Hi Hacker News! We’re Vadim and Chris from Highlight.io [1]. We do web app monitoring and are working on using LLMs/embeddings to add new functionality to our error monitoring product. Given that there’s a lot of founders/engineers using LLMs in their products, we figured we’d share how we built the new functionality, their impact on our workflows, and how you can try it out. Our goal was to build two features: (1) tagging errors (e.g. deeming an error as “authentication error” or a “database error”); and (2) grouping similar errors together (e.g. two errors that have a different stacktrace and body, but are semantically not very different). Each of these rely heavily on comparing text across our application. After some experimentation with the OpenAI embeddings API [3], we went ahead and hosted a private model instance of thenlper/gte-large (an open-source MIT licensed model), which is a 1024-dimension model running on an Intel Ice Lake 2 vCPU machine on Hugging face [4]. Our general approach for classifying/comparing text is as follows. As each set of tokens (i.e a string) comes in, our backend makes a request to an inference endpoint and receives a 1024-dimension float vector as a response (see the code here [5]). We then store that vector using pgvector [6]. To compare any two sets for similarity, we simply look at the Euclidian distance between their respective embeddings using the ivfflat index implemented by pgvector (example code here [7]). To tag errors, we assign an error its most relevant tag from a predetermined set decided by us. For example, if we tag an error as an "authentication error" or a "database error", we can allow developers to have a starting point before inspecting an issue.(see the logic here [8]). Anecdotally, this approach seems to work very well. For example, here are two authentication errors that got tagged as “Authentication Error”: * Firebase: A network AuthError has occurred * Error retrieving user from firebase api for email verification: cannot find user from uid. We also use these error embeddings to group similar errors. To decide whether an error joins a group or starts a new one, we decide on a distance threshold (using the euclidean distance) ahead of time. An interesting thing about this approach, compared to using a text-based heuristic, is that two errors with different stack traces can still be grouped together. Here’s an example: * github.com/highlight-run/highlight/backend/worker.(*Worker).ReportStripeUsage * github.com/highlight-run/highlight/backend/private-graph/graph.(*Resolver).GetSlackChannelsFromSlack.func1 Both reported as `integration api error` as they involve the Stripe and Slack integrations respectively. The neat thing is that the LLM can use the full context of an error and match based on the most relevant details about the error. We have rolled out a first version of the error grouping logic to our cloud product [9], and there’s a demo of all the functionality at [2]. Long-term, the HN community has other ideas of what we could build with LLM tooling in observability, we’re all ears. Let us know what you think!

Show HN: XRain – Explore rainfall statistics around the world https://bit.ly/3RAaure

Show HN: XRain – Explore rainfall statistics around the world Last year I launched a website that allow people to see rainfall statistics that are based on satellite data. Historical rainfall information usually comes from rain gauges, and while these are fantastic there are many parts of the world that don't have many long term gauges, or where that data is hard to access. Satellite data can be an invaluable source of information for those data-scarce areas. The business model is to sell "extreme precipitation" data that can be used for flood modelling. Unfortunately, after a year I still haven't made a single sale. I've tried various ways of advertising, mainly via messaging people on LinkedIn who would actually have a use for it. I'm still proud of what I've built, even if it's a flop! Fun feature: jump to a completely random part of the world by clicking the "Random" button. I'd love feedback on anything, such as how to improve the UI/UX of the mobile view of the map page. https://bit.ly/45aviZs September 27, 2023 at 04:36AM

Show HN: Nature – Modern System-Level Programming Language and Compiler This is an introduction to the "Nature" project: https://bit.ly/3ET9TJS I am the author of the Nature language, and today I have released the 0.4.0-beta version. For detailed updates, please see https://bit.ly/3LZJhuL Now, Nature can easily interact with C language. It is anticipated that in about six months, Nature will release a version available to the community. By then, there will be stable syntax API, a complete standard library, and support for development tools. Moreover, all the standard library code in Nature will be merged into the main repository. Contributions are welcome. If you want to follow the development of Nature more closely, you can 'watch' it on GitHub to keep up with the progress. I also hope to receive your 'star' support, as it will give me great motivation. https://bit.ly/3rv8t59 September 26, 2023 at 01:21AM
