After 10 years in defense tech, watching missile attacks in Ukraine and the Middle East made it clear how little most people really get about air defense. So I'm builiding this simulator which drops you into the operator’s seat. You can test out different scenarios and build an air defense network against various types of threats (stats from real world). Also have Ukraine, Israel-Iran scenarios. https://airdefense.de…

Does this take into account the new "drone attacks from within the country's borders" scenario?

https://spring-agriculture.com/ Autonomous robotics for sustainable agriculture. Based in the south of the UK. Prototypes of an autonomous mechanical farm-scale weeding robot currently beginning real-world testing. Still a huge amount of work to do though. Hardware and software developed fairly much from scratch, not using ROS (for not entirely crazy reasons...); everything written in Rust which I find well suited to…

I invested in Small Robots Co (https://smallrobotco.com/) who were doing something similar. They had a good product, good brand, raised some funding, and were starting to get traction, with robots in trials on a number of farms, but at the end of the day they ran out of funding before they reached default-alive.

It's a tough space - convincing farmers to give it a go and running trials takes time and the UK isn't a very startup-friendly environment - investors are too often looking for a quick return.

This is such an important area - it's only going to become more critical to be able to grow more food whilst using less fertiliser and weed killer - so I wish you the very best of luck!

Very Cool!! I'm pretty new to the robotics world, why are you avoiding ROS?

Working on https://www.space4ads.com - an Out of Home Advertising Marketplace that connects advertisers with underutilized commercial spaces. Think Airbnb, but for ad placements. We're targeting vacant storefronts, construction walls, cargo vans, box trucks, 18-wheelers, and basically any commercial space with foot traffic or vehicle visibility that's not being monetized for advertising.

I'm making a kind of "Tinder for hiking trails". I live in Switzerland and am (like many people here) an avid hiker. There are a lot of great hiking websites but they all suffer from the same problem: They are ultimately just a list of hiking routes that you need to plan around. Because I do a hike almost every week, the extra planning has become an overhead that takes time out of my life: how far away is it, what tr…

Interested...from Italy! some "hike with kids" filters could be interesting too. I don't have much time at the moment, but if you need an help let me know (even just for brainstorming)

https://github.com/nixiesearch/nixiesearch

A Lucene-based search engine on top of S3 block storage.

Index schema is immutable (but supports migrations), so you cannot just screw up your index.

Separate indexer/searcher tiers, so heavy indexing load does not affect search latency.

And embedding/reranker local inference, so you can run the whole AI search within a single docker container.

This weekend, my modified Android/mobile Point of Sale (POS) app was used to celebrate the 100th anniversary of our village's volunteer firefighting organization. The standard fiscal POS app was adapted to support a sort of low-trust swarm of waiters who used the app to collect orders. These orders were then transferred to a few high-trust cashiers by scanning QR codes generated on the waiters' apps. After receiving…

Any way we could test this system? Is the code open source?
