Show HN: macOS GUI for running LLMs locally

Hello HN,<p>I've been working on this project for a while, and it has been in an "open" beta for some time. I finally believe it's ready for its first release.<p>I hope you like it.<p>Here are some potential questions that may arise:<p>1. How does it compare to LM Studio? It's likely that if you're already using LM Studio, you'll continue to do so. This project is designed to be more user-friendly.<p>2. Is it open-source? No, it is not.<p>3. Does it use any open-source libraries? Yes, it uses llama.cpp and a few others, as indicated in the license information included with the application.<p>4. Why is not using electronjs? Two reasons, I wanted total control over the whole tech-stack and second, I wanted to be able to send this to my friends over iMessage.<p>5. Does it support Intel macs? It should, but I couldn't test it.<p>6. Does it support older macOS? 12.6 is the lowest version at the moment.<p>7. Is XXX a bug? Probably :)

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.<p>Github Repo: <a href="https://github.com/hyperdxio/hyperdx">https://github.com/hyperdxio/hyperdx</a><p>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.<p>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.<p>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.<p>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.<p>I'm excited to share what we've been working with you all and would love to hear your feedback and opinions!<p>Hosted Demo - <a href="https://api.hyperdx.io/login/demo">https://api.hyperdx.io/login/demo</a><p>Open Source Repo: <a href="https://github.com/hyperdxio/hyperdx">https://github.com/hyperdxio/hyperdx</a><p>Landing Page: <a href="https://hyperdx.io">https://hyperdx.io</a>

Show HN: Conway's Game of Chess

Chess, but each square also follows the rules of Conway's Game of Life.<p>Only your own pieces count as neighbours when deciding births/deaths.<p>For births, an empty square must have 3 neighbours for 2 consecutive turns.<p>For deaths, a piece must have <2 or >3 neighbours for 3 consecutive turns.<p>This is a simple proof of concept I made with python and curses.<p>You can play with a friend locally or over a socket connection.<p>Controls: Arrow keys to move the cursor, enter/space to select and move a piece, u or backspace to undo a move, r to redo a move, q or escape to quit, s to perform a move with stockfish if installed (useless since it has no knowledge of this variant), any other key to unselect a currently selected piece.

Tell HN: Stripe Destroyed Our Business after 7 months of building our product

We only charge when their customers pay them and we charge via application fee feature of Stripe Connect.<p>We use Stripe Standard Connect where if you have existing Stripe account you can work with us to get new clients<p>Few days ago, after integrating CRMs, 7 months of intense work on building our advertising platform and getting 5 clients (5 connected accounts) we finally went live and it was successful in terms of business where our tech brought 30k worth of sales in couple days, all that work finally paid off and I could finally pay our team as none have been paid yet<p>and today Stripe closed our account froze our funds and marked our account "fraudulent" and saying "unauthorized payments" and sent us appeal form which all you can do is upload company formation documents which we did and they automatically denied it<p>I need everyone to know the real face of Stripe, now if this issue cannot be resolved after all the work done, I need to find a way to pay our team or shut down the company and lose all my team

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.

Show HN: Every Breath You Take – Heart Rate Variability Training

Through controlled breathing it is possible to regulate your body's stress response. I've built an app to measure and train this effect with a Polar H10 Heart Rate monitor.<p>With every breath you take, you can set the pace of your breathing rate, measure your breathing control with the chest accelerometer, and see how heart rate variability responds.
