New best story on Hacker News: Show HN: Drop-in SQS replacement based on SQLite

Show HN: Drop-in SQS replacement based on SQLite 487 by memset | 122 comments on Hacker News. Hi! I wanted to share an open source API-compatible replacement for SQS. It's written in Go, distributes as a single binary, and uses SQLite for underlying storage. I wrote this because I wanted a queue with all the bells and whistles - searching, scheduling into the future, observability, and rate limiting - all the things that many modern task queue systems have. But I didn't want to rewrite my app, which was already using SQS. And I was frustrated that many of the best solutions out there (BullMQ, Oban, Sidekiq) were language-specific. So I made an SQS-compatible replacement. All you have to do is replace the endpoint using AWS' native library in your language of choice. For example, the queue works with Celery - you just change the connection string. From there, you can see all of your messages and their status, which is hard today in the SQS console (and flower doesn't ...

New best story on Hacker News: Show HN: I am building an open-source Confluence and Notion alternative

Show HN: I am building an open-source Confluence and Notion alternative 499 by Pi9h | 196 comments on Hacker News. Hello HN, I am building Docmost, an open-source collaborative wiki and documentation software. It is an open-source alternative to Confluence and Notion. I have been working on it for the past 12 months. This is the first public release (beta). The rich-text editor has support for real-time collaboration, LaTex, inline comments, tables, and callouts to name a few. Features - Collaborative real-time editor - Spaces (Teamspace) - User permissions - Groups - Comments - Page history - Nested pages - Search - File attachments You can find screenshots of the product on the website. Website: https://docmost.com Github: https://ift.tt/EDeuInS Documentation: https://ift.tt/JsvTCYP I would love to hear your feedback. Thank you.

New best story on Hacker News: Show HN: I made a puzzle game that gently introduces my favorite math mysteries

Show HN: I made a puzzle game that gently introduces my favorite math mysteries 633 by MCSP | 124 comments on Hacker News. This is the first iteration of a short game I’m making that tries to interactively explain some of my favorite math questions / ideas. My goal is mostly to get the player curious and not necessarily to explain absolutely everything. There were a lot of fun technical parts to building this: - For implementation reasons, it’s much easier if the lines all have integer intersection points with each other. To do this, when a new line is added I “cheat” by rounding intersections to integers and then splitting the old lines at the intersection into new linds (with potentially different slopes) going through the rounded point - I had to draw semi accurate maps of actual places (UK, South America, US west coast) in the HTML canvas using just line segments. I tried a few different solutions, including using SVG data. I ended up using the topojson library to give nice line...

New best story on Hacker News: Show HN: We Made The World's Smallest and Cheapest Network Switch

Show HN: We Made The World's Smallest and Cheapest Network Switch 510 by Hello9999901 | 141 comments on Hacker News. Hello, we're Max and Byran from MUREX Robotics, a high school robotics team from Exeter, New Hampshire. We are super proud to have made this open source piece of technology! It is only 6.9 dollars (actually!) from JLCPCB :) I hope you like it. You can find us at byran@mrx.ee and max@mrx.ee as well if you have any questions. We will be putting a small run of these boards for sale somewhere (we have <25 units of stock), probably for $10+shipping. Let us know if you're interested in more! Board files for everything we make is here: https://github.com/murexrobotics/electrical-2024

New best story on Hacker News: ARC Prize – a $1M+ competition towards open AGI progress

ARC Prize – a $1M+ competition towards open AGI progress 451 by mikeknoop | 204 comments on Hacker News. Hey folks! Mike here. Francois Chollet and I are launching ARC Prize, a public competition to beat and open-source the solution to the ARC-AGI eval. ARC-AGI is (to our knowledge) the only eval which measures AGI: a system that can efficiently acquire new skill and solve novel, open-ended problems. Most AI evals measure skill directly vs the acquisition of new skill. Francois created the eval in 2019, SOTA was 20% at inception, SOTA today is only 34%. Humans score 85-100%. 300 teams attempted ARC-AGI last year and several bigger labs have attempted it. While most other skill-based evals have rapidly saturated to human-level, ARC-AGI was designed to resist “memorization” techniques (eg. LLMs) Solving ARC-AGI tasks is quite easy for humans (even children) but impossible for modern AI. You can try ARC-AGI tasks yourself here: https://ift.tt/UdgfHn4 ARC-AGI consists of 400 public trai...

New best story on Hacker News: Ask HN: What was your most humbling learning moment?

Ask HN: What was your most humbling learning moment? 470 by spcebar | 603 comments on Hacker News. I've worked on large products for large and small companies and written tens of thousands of lines of code across my career, solving complex, abstract, challenging technical problems in a variety of languages on a variety of platforms, sometimes under difficult conditions. I have often been a resource for my friends and co-workers when they have programming or technical questions. I only recently learned how to correctly raise and lower window blinds--I had been doing it wrong my entire life. It was maybe the dumbest I have ever felt, and was a humbling reminder of how much I don't know about how much I don't know. Have you had similar experiences?
