Designing bridge trusses with Pytorch autograd
You can use Pytorch for more than just Neural Networks - its autograd is super powerful for any problem where you need gradients (and are too lazy to calculate them yourself...)!
Show HN: GodotOS – Fake operating system interface made in the Godot engine
GodotOS, an operating system interface created entirely in Godot! Browse folders, edit text files, view images, play games, and more in one cohesive polished interface that can even be used on the web.<p>Note that GodotOS is more of a toy than a serious project. It's meant to push the limits on UI design in Godot while creating a desktop that is minimalist, distraction-free, and aesthetically pleasing. Any feedback is greatly appreciated!<p>Apologies for posting again, but I forgot to include "Show HN" in the title, and when I did post yesterday Hackernews almost immediately went down for over an hour, which is unfortunate.

Show HN: Dbeel – A distributed thread-per-core db
For a while now I had the urge to learn how to pick the "right" database for projects, I looked around online at different databases to try to understand their different traits, and was bombarded with marketing instead of actual info on the advantages and drawbacks.<p>The only solution for me was to learn some database internals (I read the wonderful book written by Alex Petrov), and the problems seemed so interesting, I could not fight the urge and went ahead with trying to write my own db.<p>Anyway, ~9 months have passed and I feel like I'm "done", I have learned a ton, and really proud of dbeel.<p>Now I can pick a database and way more easily understand what are its most defining traits.<p>Some short time in the future, I will release a blog post or something, where I will write about the fundamental problems you need to solve when writing a performant data system like a database, so stay tuned :)

Show HN: Peer-to-peer mini r/place with Proof of Work
Hi HN,<p>This is a site where users can submit content and the shortest SHA256 value of nonce+content among them will make the site display the content. Very basic, without a blockchain. It's a static site with WebRTC and peer-to-peer.<p>Why? I wanted r/place (Reddit canvas where users collaborate on a pixel grid), but with proof of work. This is my progress so far. It's a WebRTC app with peer to peer connectivity that forwards the best hashed values to other users, which verify them, display them and pass them on.<p>There are many many improvements to be done (especially I should probably use something like libp2p-gossipsub, otherwise scale is probably an issue) and more ideas to be implemented, and I'm sure there are bugs. But I didn't find any similar projects yet (except blockchains of course).<p>Hope you like it!

Show HN: I made an online Webhook Tester
Hi HN! Last year, I built LocalCan app in which you can develop apps using .local domains and Public URLs.<p>Although it allows for testing webhooks too, I wanted to give back and create a free online tool specifically for that purpose! And so, I've made Webhook.cool<p>Simply use your unique webhook URL to send any webhook to it from services like Shopify, Slack, Mailchimp, Trello, GitHub, PayPal, Discord, and Jira.<p>Give it a try and let me know how if you have any feedback.

Show HN: Annie – An Uncensored AI Girlfriend
A few day ago I launched an AI girlfriend service. It's completely uncensored, so compared to other AI girlfriend services you are not restricted to dive NSFW topics. She can even send you voice messages and pictures of her! You can also send voice messages and pictures your self and she will understand you just fine.
To get started, you just need a Telegram account.<p>It's my first side project which I launched publicly, so I would really appreciate your feedback!
Show HN: Quickwit – OSS Alternative to Elasticsearch, Splunk, Datadog
Hi folks, Quickwit cofounder here.<p>We started Quickwit 3 years ago with a POC, "Searching the web for under $1000/month" (see HN discussions [0]), with the goal of making a robust OSS alternative to Elasticsearch / Splunk / Datadog.<p>We have reached a significant milestone with our latest release (0.7) [1], as we have witnessed users of the nightly version of Quickwit deploy clusters with hundreds of nodes, ingest hundreds of terabytes of data daily, and enjoy considerable cost savings.<p>To give you a concrete example, one company is ingesting hundreds of terabytes of logs daily and migrating from Elasticsearch to Quickwit. They divided their compute costs by 5x and storage costs by 2x while increasing retention from 3 to 30 days. They also increased their durability, accuracy with exactly-once semantics thanks to the native Kafka support, and elasticity.<p>The 0.7 release also brings better integrations with the Observability ecosystem: improvements of the Elasticsearch-compatible API and better support of OpenTelemetry standards, Grafana, and Jaeger.<p>Of course, we still have a lot of work to be a fully-fledged observability engine, and we would love to get some feedback or suggestions.<p>To give you a glance at our 2024 roadmap, we planned to focus on Kibana/OpenDashboard integration, metrics support, and pipe-based query language.<p>[0] Searching the web for under $1000/month: <a href="https://news.ycombinator.com/item?id=27074481">https://news.ycombinator.com/item?id=27074481</a><p>[1] Release blog post: <a href="https://quickwit.io/blog/quickwit-0.7" rel="nofollow">https://quickwit.io/blog/quickwit-0.7</a><p>[2] Open Source Repo: <a href="https://github.com/quickwit-oss/quickwit">https://github.com/quickwit-oss/quickwit</a><p>[3] Home Page: <a href="https://quickwit.io" rel="nofollow">https://quickwit.io</a>

Show HN: I made an interactive math crossword puzzle with infinite levels
Hey there! I'm the brains behind the math crossword game on my site.<p>This game is all about making math a little more fun – users just drag and drop numbers to fill in the blanks and move on to the next level if they get it right.<p>Let me know if face any issues or have any suggestions! :)
