Show HN: An update to my friendly C++ WebGPU open source library Since my last post was received well, I decided to post an update here :) wgpu-lab is a library to get you started with developing WebGPU apps in C++ It's based on google's dawn implementation and is an open work in progress. Your contributions are welcome ! In my previous release, it was still difficult to build and use the library. This should now be fixed! https://bit.ly/4e2dXGR October 30, 2024 at 02:10AM

Show HN: I built an app to use a QR code as my doorbell https://bit.ly/4hr7VlO

Show HN: I built an app to use a QR code as my doorbell I didn’t have a doorbell before (multiple reasons) and my house feels unwelcoming without one. So I built a doorbell app that uses a QR code - visitors scan the QR code to ring the doorbell and I get notified on my phone. Here is an example of the QR code I have on my door. You can scan it and say hello: https://bit.ly/40phETS This was also a great excuse to build my first app for Android and iPhone. I’d love to get some feedback before I spend more time polishing the app. Please try it out and feel free to ask me any questions!

Show HN: I made a utility I named pmake to generate project files https://bit.ly/3YH4YXa

Show HN: I made a utility I named pmake to generate project files My code works but it could probably be improved. Something I'm worried about is this part of the code printf ' ;;; Directory Local Variables -*- no-byte-compile: t -*- ;;; For more information see (info "(emacs) Directory Variables") (setq flycheck-gcc-include-path "'$indir'") ' > .dir-locals.el It generates a .dir-locals.el file that forces flycheck (an emacs package) to look inside the include directory inside the project folder. I'm a little worried about whether setq is the right approach. Any help would be appreciated! https://bit.ly/3AdbNWZ October 29, 2024 at 06:04AM

Show HN: Trench – Open-source analytics infrastructure https://bit.ly/3C1sbKB

Show HN: Trench – Open-source analytics infrastructure Hey HN! I want to share a new open source project I've been working on called Trench ( https://bit.ly/3YmYmvy ). It's open source analytics infrastructure for tracking events, page views, and identifying users, and it's built on top of ClickHouse and Kafka. https://bit.ly/40ia0un I built Trench because the Postgres table we used for tracking events at our startup ( https://bit.ly/3YlvIel ) was getting expensive and becoming a performance bottleneck as we scaled to millions of end users. Many companies run into the same problem as us (e.g. Stripe, Heroku: https://bit.ly/3YqjP6H ). They often start by adding a basic events table to their relational database, which works at first, but can become an issue as the application scales. It’s usually the biggest table in the database, the slowest one to query, and the longest one to back up. With Trench, we’ve put together a single Docker image that gives you a production-ready tracking event table built for scale and speed. When we migrated our tracking table from Postgres to Trench, we saw a 42% reduction in cost to serve on our primary Postgres cluster and all lag spikes from autoscaling under high traffic were eliminated. Here are some of the core features: * Fully compliant with the Segment tracking spec e.g. track(), identify(), group(), etc. * Can handle thousands of events per second on a single node * Query tracking data in real-time with read-after-write guarantees * Send data anywhere with throttled and batched webhooks * Single production-ready docker image. No need to manage and roll your own Kafka/ClickHouse/Nodejs/etc. * Easily plugs into any cloud hosted ClickHouse and Kafka solutions e.g. ClickHouse Cloud, Confluent Trench can be used for a range of use cases. Here are some possibilities: 1. Real-Time Monitoring and Alerting: Set up real-time alerts and monitoring for your services by tracking custom events like errors, usage spikes, or specific user actions and sending that data anywhere with Trench’s webhooks 2. Event Replay and Debugging: Capture all user interactions in real-time for event replay 3. A/B Testing Platform: Capture events from different users and groups in real time. Segment users by querying in real time and serve the right experiences to the right users 4. Product Analytics for SaaS Applications: Embed Trench into your existing SaaS product to power user audit logs or tracking scripts on your end-users’ websites 5. Build a custom RAG model: Easily query event data and give users answers in real-time. LLMs are really good at writing SQL The project is open-source and MIT-licensed. If there’s interest, we’re thinking about adding support for Elastic Search, direct data integrations (e.g. Redshift, S3, etc.), and an admin interface for creating queries, webhooks, etc. Have you experienced the same issues with your events tables? I'd love to hear what HN thinks about the project. https://bit.ly/4foGt6G October 25, 2024 at 03:07PM

Show HN: Finstruments - Financial instrument library built with Python https://bit.ly/4eY8br2

Show HN: Finstruments - Financial instrument library built with Python finstruments is a Python library designed for modeling financial instruments. It comes with the core financial instruments, such as forwards and options, out of the box, as well as position, trade, and portfolio models. finstruments comes with the basic building blocks, making it easy to extend and build new instruments for any asset class. These building blocks also provide the functionality to serialize and deserialize to and from JSON, enabling the ability to store a serialized format in a document database.

Show HN: Jist searches JSON 3x faster than jq https://bit.ly/4hzYkth

Show HN: Jist searches JSON 3x faster than jq Hi HN, jist is a JSON path search tool that feels like accessing a JavaScript object. It’s 3x faster than jq for the same use case, and over 2000x more memory efficient when searching a 3.3GB file for the last element (jist reads data in chunks so has constant space use). It doesn’t implement pattern matching yet. A feature I’m looking to add is generating a full JSON schema using the same streaming approach so stay tuned!

Show HN: Create Waitlist Pages I decided to launch FastWaitlist because I was facing a problem with validating my own product ideas. I noticed the lack of tools that: 1. Let you create waitlist pages fast (always faced complicated page builders) 2. Have conversion optimized templates (we have 5 and we're planning to add more) 3. Support custom domains That's exactly why I launched FastWaitlist. It has solved a huge pain point for me and I hope it'll do the same for you. https://bit.ly/3NDpHoi October 25, 2024 at 07:17PM
