Gis.chat – a Geospatial Community
Hi folks! I'm excited to show you gis.chat, a geospatial chat platform in both senses: a platform about geospatial topics and a geospatial platform itself, referencing the location of our communities. The setup is fairly simple and reproducible: a plain Zulip instance and a homepage with geospatial search capabilities. It seems almost trivial but it has some very nice features. I guess you should be familiar with Zulips stream/topic model to follow along (https://zulip.com/help/streams-and-topics). The core idea is that there are city-specific streams (currently…

In plain words
Gis.chat is a chat platform built on Zulip that organizes communities by geographic location. It is designed for people interested in geospatial topics and local discussions, allowing users to join city-specific streams or interact with location-based communities.

The geospatial community
A place for anyone interested in geospatial topics such as GIS, geo data science, earth observation, social sciences, climate change, urban planning, architecture... everyone is welcome! An independent open source project based on Zulip hosted on Hetzner with 100% hydropower in Germany. A geospatial chat in both senses: a platform about geospatial topics and a geospatial platform itself, referencing the location of our communities. Communicate your next meetups or simply get to know the spatial folks in your area! You can also use gis.chat as a normal forum about interesting topics, events or Q&A tool. It's free, open source and you can even peak at some channels without account! Say hi in…from gis.chat

ChatGPT UI for rabbit holes2024 · delve.a9.io · ▲766I was inspired by the way ChatGPT writes bullet lists, then invites you to "delve" deeper. This is an interface that reifies that rabbit-holing process into a tiling layout. The model is instructed to output hyperlink-prompts when it mentions something you might want to delve into. Lots of features to add (sessions, sharing, navigation, highlight-to-delve, images, ...). Would love to hear other usecases and ideas!

Geofenced chat communities anyone can createNov 2025 · vicinity.social · ▲57Hi HN, I built a location-based chatroom with Discord-like servers. This started as a portfolio project to learn WebSockets but has spiraled into something else entirely. There are two features right now: Drop - Single chatrooms that can only be seen within a specified radius and only last for a time less than 48 hours chosen by the user. Hubs - Geofenced servers modeled after Discord. These are not time restricted. They can be created by anyone and the creator becomes the admin able to add channels and set rules. When a user enters the location’s area, they can join the hub and continue…
