Building a little dashboard for our solar system. Running on a mini PC in the office closest. Bun, React, DuckDB https://solar.franz.hamburg/

... solar power system. Though a dashboard for the Solar system would've been neat to see too :)

Thanks, yes it’s obviously for a power system.

I’m building Ganttify for a while now https://gantt-chart.com

The goals is to become THE Gantt chart add-on for anything. Currently works with Todoist, Basecamp and Trello. I’m struggling to find more markets.

It’s basically “Turn X into an editable timeline with syncing capabilities and dependencies”

Open to suggestions and ideas how I can make this take off.

I’m currently in the process of consolidating every integration into a single account. Previously (currently) it was “Ganttify for Trello” or “Ganttify for Basecamp”. It will become “Ganttify, connect one or more integrations to your liking”.

That might help simplify things for users I suppose.

https://fooqux.com/ - an experimental tech article aggregator. For several years now, I've had a routine of collecting articles on topics that interest me throughout the week and then reading them over the weekend. To help organize and streamline this process, I created this website. The main idea is to gather tech articles in one place and process them with a LLM — categorize them, generate summaries, and try experi…

That looks great. Are you aiming to automate the gathering process or let users self-serve by creating their own list of bookmarks (then processing the pages on your side)?

Thanks. For now, I don't have any plans to automate this process. Users simply add articles to the site, as in other aggregators, and can filter content by tags.

What would the ideal process of working with this kind of site look like for you?

I'm working on Habitat. It's a free and open source, self-hosted platform for communities to discover and discuss their local area. The plan is for it to be federated.

In the last month or so I've been solely focused on plans and content for my instance for my local town, so there hasn't been any programming for a little while but I'll be jumping back into it in weeks to come.

Earlier quoted context omitted.

Hi, this looks amazing! Can't wait to check it out properly tonight. What are you using for numerical integration? I did this last month: https://www.nhatcher.com/three-body-periodic/ https://github.com/nhatcher/three-body-periodic There are a couple of half baked integrators there :)

Its an implementation of a pretty standard integrator used by astronomers informally called "RADAU", but it is not exactly the same RADAU you would find elsewhere. Basically it is about as good as you can typically get for multi-step integrators, tuned for speed not precision though. Note that how the code is laid out you cant really simulate non-solar system masses. Its really aimed at massless objects in the solar…

Thanks! Understood, I was more thinking along the lines of reading your code to learn something new. I wish I had infinite time

I have 2, not yet sure where to focus on so both for now

https://YouGotPicked.com - A simple list picker tool (for when you can't decide between options)

https://Drop.Top - A lightweight emoji-based feedback widget in minutes, so real users can drop contextual bugs, suggestions & ratings — all tied to session replays. See trends, sentiment & hotspots in real time, then feed feedback straight into your Jira/Slack/analytics stack.

Currently bootstrapping a SaaS side project: https://diplomium.com Diplomium helps educators and event organizers create and deliver authenticated certificates at scale. Instead of manually designing and emailing PDFs, you upload a simple Excel, pick a template, and the system generates + sends personalized certificates automatically—each with a unique QR code for instant validation. The bigger picture: Certificates…

Wow, nice project. May I ask how do you generate images under the hood? Something like browser that does screenshot?

I am working on a answer engine for Hindu Scriptures and old Sanskrit works. I already have a corpus of all the documents which are indexed and currently working on a LLM based answer engine that focuses on answering questions from Vedas and Upanishads and Mahabharata (for ex). Think perplexity but completely focused on Sanskrit sources with proper quotations from the exact verses where the answers are found.

Planning to release this into the wild for people to use. I currently am struggling on how to fund this properly as the server costs are going to be huge for such an effort (search engine + LLM).
