Show HN: HyperDX – open-source dev-friendly Datadog alternative https://bit.ly/44RhuDa

Show HN: HyperDX – open-source dev-friendly Datadog alternative Hi HN, Mike and Warren here! We've been building HyperDX (hyperdx.io). HyperDX allows you to easily search and correlate logs, traces, metrics (alpha), and session replays all in one place. For example, if a user reports a bug “this button doesn't work," an engineer can play back what the user was doing in their browser and trace API calls back to the backend logs for that specific request, all from a single view. Github Repo: https://bit.ly/3sWeqbM Coming from an observability nerd background, with Warren being SRE #1 at his last startup and me previously leading dev experience at LogDNA/Mezmo, we knew there were gaps in the existing tools we were used to using. Our previous stack of tools like Bugsnag, LogRocket, and Cloudwatch required us to switch between different tools, correlate timestamps (UTC? local?), and manually cross-check IDs to piece together what was actually happening. This often made meant small issues required hours of frustration to root cause. Other tools like Datadog or New Relic come with high price tags - when estimating costs for Datadog in the past, we found that our Datadog bill would exceed our AWS bill! Other teams have had to adjust their infrastructure just to appease the Datadog pricing model. To build HyperDX, we've centralized all the telemetry in one place by leveraging OpenTelemetry (a CNCF project for standardizing/collecting telemetry) to pull and correlate logs, metrics, traces, and replays. In-app, we can correlate your logs/traces together in one panel by joining everything automatically via trace ids and session ids, so you can go from log <> trace <> replay in the same panel. To keep costs low, we store everything in Clickhouse (w/ S3 backing) to make it extremely affordable to store large amounts of data (compared to Elasticsearch) while still being able to query it efficiently (compared to services like Cloudwatch or Loki), in large part thanks to Clickhouse's bloom filters + columnar layout. On top of that, we've focused on providing a smooth developer experience (the DX in HyperDX!). This includes features like native parsing of JSON logs, full-text search on any log or trace, 2-click alert creation, and SDKs that help you get started with OpenTelemetry faster than the default OpenTelemetry SDKs. I'm excited to share what we've been working with you all and would love to hear your feedback and opinions!

Show HN: LLM Powered Keyboard [video] Hey HN, I'm excited to share Taikoboard, a mechanical keyboard with LLM powered autocomplete. I made this keyboard for myself so I could use LLM-powered autocomplete in apps that didn't have this feature. Although more apps have started integrating LLMs, there's a large number of software tools that don't support this. Taikoboard bridges that gap, making the AI autocomplete experience universal. Would love to hear feedback, answer questions, or discuss potential use cases you see for Taikoboard. https://www.youtube.com/watch?v=BbMSWZKrrcI September 18, 2023 at 01:14PM

Show HN: Me and my buddy made $20 with a Stripe link and a Tweet https://bit.ly/44Qvi0R

Show HN: Me and my buddy made $20 with a Stripe link and a Tweet Hi there, So a buddy a couple of days ago came up with the idea for a new SaaS product regarding gpt and image generation. We did a quick MVP that barely works, it breaks almost 50% of the time but we still wanted to validate the idea before going all in. We have almost 1k followers on Twitter together. Did a quick post describing the idea with a stripe link in the comments with a 5$ value, no landing page, and no shipped product. In exchange, the buyers become beta users. Around 30 mins later we got our first sale next 30 mins another 5$ and so on. Do we consider the idea validated? The short answer is no, We gained some initial momentum but we can't call it a business yet, not until we are starting to get recurring revenue. What next? We created a notion file with multiple marketing channels we plan to test out and see which one is the best. We also created a list full of websites to submit our product and we are tracking the traffic we are going to get from each of them. PS: If you are curious, this is the product https://bit.ly/3sV2I14 September 17, 2023 at 04:16PM

Show HN: ARA Records Ansible and makes it easier to understand and troubleshoot Hey HN, long time lurker here. I humbly present ara which is a project I created back at Red Hat in 2016 (before AWX was open source) to make my life easier working with distributed and large scale Ansible playbooks. It is designed to be simple and compatible with however you're already running Ansible today without needing to change much of your existing workflows. My time and skills are limited but I have learned a lot and I am happy with how the project has steadily improved over the years with the much appreciated help of contributors. If you'd like to read more about the project, the blog might be interesting: https://bit.ly/3rmX5bh If you'd like to help, contribute or chat, feel free to hop on IRC, Slack or Matrix: https://bit.ly/45RBx5V The best way to stay up to date with the project is on Mastodon: https://bit.ly/460MhyY I will be here for a while to reply to comments and answer questions. https://bit.ly/3rmk9a8 September 17, 2023 at 02:58PM

Show HN: I made a browser extension for building your own custom HN themes https://bit.ly/3ZjUkUG

Show HN: I made a browser extension for building your own custom HN themes Hi HN! I’ve spent the last few weeks writing a browser extension that lets users write their own HN themes using Handlebars and CSS. It works by converting the current Hacker News page’s content into an object that is made available to the user-defined Handlebars templates. There is a built-in code editor that makes writing themes super easy and you can see changes in real-time. If you don’t want to write a theme from scratch, there are premade themes available or you may import one made by somebody else. It is shipped with Bootstrap so you can get pretty far without needing to write a lot of custom CSS. Material icons are also included so your themes get iconography out of the box. Any theme can be toggled into dark mode with a single click. It is open-sourced under the MIT license so feel free to use any of the code in the linked repo[0]. Additionally, I’ve put together a short demo video on YouTube[1]. If you decide to check it out, let me know of any feedback and please share any themes you create! I’d be happy to answer any questions. [0] https://bit.ly/3t1M93C [1] https://youtu.be/6DxLJQrKXa0 https://bit.ly/3PoHVKC September 17, 2023 at 02:46PM

Show HN: Dead simple API for Retrieval Augmented Generation https://bit.ly/45SVJEp

Show HN: Dead simple API for Retrieval Augmented Generation Hello everyone, I am the developer of eazyrag.com, and here is the problem I am trying to solve. When I was working on usegrasp.com (a search engine), I integrated the LLM answer engine, which is basically implementing a retrieval augmented generation (RAG) pipeline. First, I tried the most popular libraries available. I have to say I disliked the developer experience due to confusing APIs and complex abstractions. I wanted something like Algolia for retrieval augmented generation. So, I built eazyrag.com, which is an easy-to-use API to implement RAG with your own data inside your apps or websites. You can simply index everything and query it. You don't even need a unique ID for the content you are indexing; just send the entire documents in a single API call, and we will handle chunking, splitting, embedding, and prompt with context formation, etc. Here is a demo I built: I indexed all the Bun.js docs/guides pages on EazyRAG and performed RAG on them: https://bit.ly/45TxhTm https://bit.ly/3ZnCZKU September 16, 2023 at 11:35AM

Show HN: Hello Inbox – Free email deliverability checklist for marketers After struggling with low open rates in my small lifestyle software business, I decided to go down the rabbit hole that is email deliverability, learned a bunch of things I didn't know even after being in tech for a decade. A/B tested a bunch of things and finally got good results. I then decided to put together a comprehensive checklist of everything I learned and got me results to share with others. Now I help companies fix poor email deliverability and boost their email ROI. I want this checklist to be a repository of email best practices so I'm always looking to improve and update it. Your feedback is welcome. https://bit.ly/3PG4SKR September 16, 2023 at 02:18AM

Show HN: Prompt-to-Publishable-Book https://bit.ly/44X1HCG

Show HN: Prompt-to-Publishable-Book I'm thrilled to share something I've been working on for the past year. We built your dream tool for turning the idea you wished could be a book into a book - we call it Omniscience. It goes from a single prompt to a high-quality, cover-to-cover novel or non-fiction book. You can sample our non-fiction by reading Revolutionizing Life Design ( https://bit.ly/3PsFtDc ) and Unhinged Genius ( https://bit.ly/3t38c9N ) or our fiction by reading Omni Genesis. https://bit.ly/489E4d0 Plenty of other great works are available in the library, and you can follow our book prompting guide to generate your own masterpiece in our book writing interface. Prompt detail & complexity is king. You can take it from the words of one of our early evangelical customers: "Your tool has been a veritable boon for us, resembling a gift from Heaven." You'll get full hardcover and paperback cover art, the summary, full text & outline, and even recommendations for the Amazon keywords you should use. Everything you've written over the course of your life can be behind the book - uploading your data by syncing with Drive, choosing a website, or sending a folder or file from your computer and selecting it in the book writing interface will infuse the book with the knowledge you've chosen. From now until 24 hours after the launch, your first book will be free. Every book after that is paid. Happy reading & writing!! If you like the book generator, support us on product hunt today! https://bit.ly/3sWcwYw https://twitter.com/JvNixon/status/1702833730539368780 September 16, 2023 at 02:02AM
