I'm still working on my websites. Having some problems with JavaScript precision on my calculator: https://calculateconversion.com/

Here is a quote repository pet project that I'm having fun with: https://crucialquote.com/

And a writing prompt generator from years ago that I resurrected and still love: https://writecomfy.com/

Thanks for checking it out.

Earlier quoted context omitted.

When the code is ready to be opened and I have settled for a design; right now it's very much in flux and I want to see where the vision takes me, and which challenges I encounter along the way. I'd like to apply for funding by the end of this year, when I'll have saved enough money from contracting to dedicate myself fully to this project.

From my experience I never felt "ready enough" to apply. I also underestimated, despite knowing how slow the process would be, the time required not to submit a proposal for funding but how long it would take to receive an answer. Consequently I recommend you start "too early".

Any recommendation for funding in the EU? I know of NLnet

Over the holidays I was building a wooden birdhouse with a Unifi Protect camera and a small web interface that automatically identifies the birds and shows me a simple overview over which type of bird visited how many times. Birdhouse: https://img.notmyhostna.me/cRQ1gJfZCHjQKwFrgKQj UI: - https://img.notmyhostna.me/Hnw4qcvbg1ZQCrFxzGMn - https://img.notmyhostna.me/62TFwSXSRRbCfxDz297h - https://img.notmyhostna.me/40q…

I keep working on Routing24 https://routing24.com , a free route optimization tool for businesses. It's been approx. an year since we are up and running, and we helped 100+ businesses in the US and world-wide to understand the value and savings of automated route planning, and prepared tens thousands of optimized routes for companies operating from 1 to 50 vehicles. All this keeping our operational expenses low and f…

Looks like a fantastic service. Given your product/pricing structure, I would imagine that route planning is now achievable for a whole range of services that would never have been able to use it (like local paper deliveries, small shops etc). Congrats on the launch.

I've been on-and-off working on a portable, sturdy electrical cloud chamber for a couple of months now. It's a device that lets you see ionising radiation with a naked eye, right on your desk. It's already working, but it requires so many tweaks and adjustments that make the project hard to finish-finish. It's controllable by an ESP32, can run automated cooling benchmarks (to find the power vs temp sweet spot) and is…

I'd really love to have this. Do you plan on either selling units, or open-sourcing the design?

Seconding this - love the concept and would really like to see any details you have on it.

I have been porting over my favorite Erlang library "Bitcask" to Rust. https://git.sr.ht/~tombert/feocask Called "feocask" cuz feo means "ugly" in Spanish and FeO to mean Iron Oxide for Rust. I thought it was funny. I will admit that I had help from Codex, but I did write most of it myself, and I think the design is coming out kind of neat. I have a very strict "no lock" policy [1], including lockfiles, and this shou…

Hadn't heard of the Bitcask library, but it sounds pretty cool: Bitcask is an Erlang library that provides a very fast key-value store using a log-structured hash table design. It was originally developed by Basho Technologies as the default storage backend for the Riak NoSQL database.

https://easel.games A beginner-friendly programming language for 2D games where multiplayer is automatic. Intended to be an engaging way for teenagers to learn to code by making games they can play with their friends. Like a blend of Scratch and Roblox. I've been working on this for 3 years!

Looks pretty fun. I'd suggest you include pictures or video of the actual sample games on the home page though.

Building a 22-service e-commerce platform in Rust (Runs on ~300MB RAM) I'm 17. For the past 6 months, I've been diving deep into Rust to answer a question for myself: "Is Rust actually viable for complex, enterprise-grade backend architectures, or is it just hype?" To test this, I built a full distributed e-commerce system (22 microservices, gRPC, Event-Driven) using Axum and Tokio. This is not meant as “how everyone…

You'd probably get more responses if you included a link to the project. Good luck though and kudos for building something :)

As a pathologist and neuro-oncology researcher, to save myself time trying to keep up with scientific literature, I'm working on https://www.summarized.science/ . Based topics of interest (suggestions are more than welcome), the tool queries the scientific literature for each month. Then, by quering some LLMs, it extracts themes and summaries. The tool already saves me time in my day to day life, but still needs a lo…

Can you say more about the approach you take for summarization? Are the papers short enough that you just put the whole thing in the context window of the model you’re using, or do you do anything fancy? I’ve tried out various summarization approaches (hierarchical, aspect-based, incremental refinement), and am curious what you found works best for your use case.
