Show HN: A website that gives voice to unfulfilled customer needs https://bit.ly/3RvAS5M

Show HN: A website that gives voice to unfulfilled customer needs How does it work? You just write a short title of what you want like “24/7 cafe in my town”, a short description why you need it - “I like to work late, don’t like to work at home and all coffee places close at 9” and how much you would pay per visit. If many people subscribe to your idea, hopefully someone will see it and open that coffee shop. You can also see what others want and maybe get inspired. Or you can just use the website to track your ideas. What problems am I trying to solve? 1. Many startups fail because they build something that customers do not want 2. Customers do not get services they need because their voices are not heard This project attempts to solve the two problems by giving the voice to the customers and a platform for startup founders to research customer demand backed product ideas. The project is at its earliest stage, so any feedback, bug reports and feature requests are welcome! https://bit.ly/3sZKICK September 21, 2023 at 12:47AM

Show HN: Breathwork App for Endurance Athletes https://bit.ly/3PKBB1x

Show HN: Breathwork App for Endurance Athletes Hi, I had a problem of how to get into a proper shape again after quitting smoking after 17 years, where lungs of mine were the main bottleneck. I was therefore inclined to find a solution that would help me to systematically improve my breathing pace, but since I couldn't find anything related to it, I therefore decided to solve it myself. Being a designer while also having skills of a full-stack developer, I decided to learn Swift and use Apple Watch to design one. In essence, the app is rather similar to how Strava works on Apple Watch: you start your workout session, go through with it, and then have it saved for further analysis. The real difference is that you also set your breathing pace, which will translate your heart rate to breath rate and give relevant haptic cues when to breath in and out. Since I had to build a sampler to WatchOS, I also experimented with trying the app to generate background music that would be synced to both heart and breathing rates. After scraping on domain audio samples reaching over 300GB, I then used Jupyter/Python and the process of dynamic time warping to group similar sounds to eventually create an audible journey when doing workouts. Currently it only has one track/genre for ambient, but I'm thinking of adding more styles to it soon. The app also allows for fetching all your workout data in CSV though Cloudflare's Workers, if need be. I have been mostly using it when doing my runs. I recently also went through my first half-marathon, where lungs were not the bottleneck anymore, so it seems the app seems to have some merit for people to improve their breathwork. Cheers, Andrus https://bit.ly/3ZplBFq September 20, 2023 at 12:54PM

Show HN: Focusdoro(AI) – AI assisted Pomodoro task list https://bit.ly/48oyROA

Show HN: Focusdoro(AI) – AI assisted Pomodoro task list Hi, I have always struggled with changing priorities and figuring out what to focus on a particular day. The actual priorities get missed amongst all other things in life. With the launch of Gen AI in almost all aspects of our lives, i decided to build something that can assist me in finding the right priorities and staying on them. This has helped me out for the past couple of days. I am using Openai apis for task breakdown and Daily planning bot and the rest of the site is built using Django, JS, and Tailwind. I have tried a lot of productivity tools throughout the years and Pomodoro and timer-based focused work has worked out best for me. If there are other techniques that have worked out for you, do let me know, I will try to incorporate those :) Would love honest feedback on this so that I can make this more useful to others and to myself. Looking forward to your feedback, thanks in advance :) https://bit.ly/3t30RqX September 19, 2023 at 03:43PM

Show HN: Dittofeed – 1-Click deploy, self-host Mailchimp alternative https://bit.ly/46lXfPj

Show HN: Dittofeed – 1-Click deploy, self-host Mailchimp alternative Hi HN, we've released Dittofeed v0.4.0, a significant update primarily focused on facilitating self-hosting. Dittofeed is an open source (MIT licensed) alternative to platforms like customer.io, mailchimp, klaviyo, iterable etc. Self-hosting is particularly useful if you: - Want to evaluate Dittofeed without a long-term commitment - Prefer fixed, non-volume based pricing models - Aim to keep all personally identifiable information within your own infrastructure In this version, we introduced 'Dittofeed Lite,' which merges the dashboard, API, and worker services, simplifying deployment, along with providing an easy auth setup. We've also configured a 1-Click Render deployment. The Render setup comes at a fixed cost of $39/month. However, by using alternative hosting solutions for the Postgres and ClickHouse instances (neon, clickhouse cloud), the monthly costs can be reduced to under $20. We personally feel that there’s a big problem with how existing platforms handle pricing, charging insanely high prices with low contact limits, while restricting access to really basic table stakes features. Excited to share this work, and hear your thoughts and feedback!

Show HN: Graphite – Stacked Diffs on GitHub https://bit.ly/3r9YxxW

Show HN: Graphite – Stacked Diffs on GitHub TLDR; Graphite enables a git workflow called “stacking” - the fastest way to develop and ship code, which many large tech companies have been using for years. Graphite makes stacking available to anyone with a GitHub account. Hi HN! I’m Tomas, co-founder of graphite.dev, and today we’re launching Graphite after almost two years of development in closed beta. [1] Graphite started as an internal solution to our own problem. When we (engineers from Meta, Google and Airbnb) left our previous roles, we lost access to the internal code review tools we loved. So we built our own. https://bit.ly/3sXgDDI --- Graphite is how the fastest developers ship code - it’s a developer tool that allows you to create smaller pull requests, stay unblocked, and ship faster with “stacking” (creating a set of dependent pull requests). Stacking [2] allows developers to break up large pull requests (PRs) into smaller ones that can be reviewed & merged independently, while keeping ongoing development unblocked. Engineering best practices at Google advise that a “reasonable” PR be around 100 lines, and recommend splitting PRs in order to achieve this through stacking or other methods. [3] Unlike other tools like Phabricator, Gerrit, or Sapling, Graphite syncs seamlessly with your GitHub repositories, so that you don’t have to manage any extra infrastructure. This also means that even if your teammates don’t use Graphite yet, you still can. Here’s what you can expect when you sign in to Graphite with your GitHub account: (1) First class support for stacking: At its core, Graphite enables “stacking”—a workflow used by engineers at top companies like Meta and Google to create small, dependent sets of pull requests. The Graphite CLI, web app, and VS Code extension all come together to empower engineers to start stacking. (2) Pull request inbox: You can think of this as your home page on Graphite, where you have full visibility into the status of all your PRs and know what still needs to be done across every repo, author, and stage of review. You can also create custom inboxes that filter PRs on reviewers, authors, labels, CI status, and more. (3) Streamlined code review interface: Graphite’s pull request page removes tabs and minimizes distractions, with the aim of putting your code front and center. You can use keyboard shortcuts to navigate between files and comments or to move between PRs in your stack. You can also import custom memes and gifs to add some to your reviews too! (4) AI-powered pull requests: Auto-generate a detailed description for every PR with our OpenAI integration. You can even turn your comments into suggested code changes (coming soon!). (5) Real-time notifications: Connect Graphite to your Slack workspace to stay up-to-date on review requests, comments threads, merge status, and other activity on your PRs. For smaller PRs, you can leave a review (and even merge) directly from Slack. (6) Stack-aware merges: Since Graphite is built to support a stacking workflow, it automates the manual work of rebasing PRs when it’s time to merge. You can merge your stacks with one click from the web app, or in a single command from the CLI. Feel free to take a look at our getting started guide [4] or product tour video [5] for a tutorial on how to get started, and drop your comments to us below!

Show HN: I made a CMS for Astro content collections https://bit.ly/3PJETCc

Show HN: I made a CMS for Astro content collections I like writing content in Markdown and I enjoy Astro very much. When I tried out Astro's content collections feature, I couldn't stop wondering how would a nice packaging look for it, which would smooth out the rough edges around Markdown in static websites. So I made the app that I can enjoy when writing posts on my Astro-powered blog. It's been saving me a ton of time already. I don't need to: 1. Edit in iA writer then paste into VS Code. 2. Google YAML date format. 3. Generate Unix timestamps to prefix new files with. 4. Copy paste images and write down their URLs manually. 5. Peek at collection schema to remember which frontmatter fields am I supposed to fill out. Because it's exclusively made for Astro, it can integrate deeply with it and support Astro-specific features and conventions, like where images need to be stored or how to reference entries from other collections in the frontmatter. Also, this app has the coolest name of all my projects - Darkmatter. If you own or work with an Astro website, Darkmatter can be the content editing tool that makes you want to write again. https://bit.ly/3PJeMLy September 19, 2023 at 02:06PM

Show HN: A murder mystery game built on an open-source gen-AI agent framework https://bit.ly/3rhGJAL

Show HN: A murder mystery game built on an open-source gen-AI agent framework Hey HN, Michael and Scott here. We’re open-sourcing an interactive murder mystery featuring LLM-driven character agents. Solve the mystery by finding clues, taking notes, and interrogating agents. They all have distinct motives, personality, and can impact the game in different ways (attacking you, running away, etc). Try it out, it’s pretty fun! We’re also open-sourcing the framework that we used to make and refine the agents. The goal is to create an intuitive interface for storytellers to create, debug, and test game agents. We then take those game agents and expose an API beyond just chat - such as actions, player guardrails, emotional queries, etc. We’re not done yet - there are a lot more features coming on the way: scenario-based agent evals, agent-storyline consistency management, automatic agent generation, etc. We would love to hear your feedback.

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] https://bit.ly/3PIzxqO

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
