Show HN: I am building an open-source Confluence and Notion alternative
502 by Pi9h | 197 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/cN7twzj Documentation: https://ift.tt/4dsuJmP I would love to hear your feedback. Thank you.

And what made it so good? Was there someone enforcing good practices top down? Just being in a group of great engineers? Or something else?

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
645 by MCSP | 125 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 approximations to GeoJSON maps - I use a simple backtracking algorithm to handle the live coloring of graphs - I use turf.js’s polygonize function to handle finding polygons from line segments (very happy I didn’t have to implement this myself!) - I wanted to make the game as mobile friendly as possible (don’t think I’ve nailed this quite yet) There were also a few tradeoffs I made: - I wanted give links earlier in the game for players to learn more, but I decided to wait until the end to maintain the flow of the game - In order to make the game more mobile-friendly, I generally stuck to maps with a small number of regions (at least for maps people have to interact with them). So for the most part all of the instances in the game are “easy”

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

Show HN: Every mountain, building and tree shadow mapped for any date and time
610 by tppiotrowski | 180 comments on Hacker News.
I've been working on this project for about 4 years. It began as terrain only because world wide elevation data was publicly available. I then added buildings from OpenStreetMap (crowd sourced) and more recently from Overture Maps data. Some computer vision/machine learning advancements [1] in the past few years have made it possible to estimate tree canopy heights using satellite imagery alone making it possible to finally add trees to the map. The data isn't perfect, but it's within +/- 3 meters of so. Good enough to give a general idea for any location on Earth. Happy to answer any questions. [1] https://ift.tt/qaMJKNt
