Took me bout 2 days for the initial release of the config-file-validator. I had been thinking about it for a while and was able just to knock it pretty quickly. It’s changed a LOT since initial release and 95% of that work has been from open source contributors

#212Last year, my wife and I were planning a 12 day trip and I was struggling with Google Docs moving days around while we planned our final route. Told her to give me 2 days and ended up making a small app to help us plan our trip; the first version was built over New Years weekend: https://turas.app Kept working on it and it was good enough to share to Reddit 6 days later [0]. Got a good number of users and still keep…
This is so coooool!

#213I was curious and tried to make the smallest useful android app. I was able to get the APK down to 65kb for a basic US constitution reader. For reference, the constitution is 40kb uncompressed.

#215Two years ago, on the height of Wordle's popularity I wanted to play a custom word against my colleague and ended up sending the emojis manually in the chat to each of their guesses.
That was a Friday and the same evening I had the idea to make it into one of the many derivatives and finished the same night around 3am.
Things went a bit popular from there and it wasn't long before I was contacted by companies that wanted their own branded version. That meant I had a potential product on my hand and started selling subscriptions to managed branded puzzle sites.
Fast-forward a year and I sold the weekend project for a nice sum. :)

#216a notification system that notifies backpackers whenever a highly coveted permits becomes available. made it for myself in a few hours then spent another half day setting it up so other people can subscribe. i got two subscriptions from one reddit comment, made $20 while i was out fishing!
Do you mind sharing a link? Wrote a python script to do the same thing for myself
there's not much to see except a google form for signups and gumroad link for payment. it only has glacier national park configured right now.
the notification system is a github action that runs constantly, scraping the api that makes the reservation.gov permits, and then checking if any of the subscription notifications have changed.
the sign up is a google form that triggers a zapier and adds the new notification subscription to a google sheet. the spreadsheet is used in the github action. the zapier also sends an email with a payment link to the user.
you sign up here: https://forms.gle/eftvBZwapnQb8RmT8
and that sends you a link to pay: https://smcalilly.gumroad.com/l/qxvph
and then it's setup.

#218https://github.com/NotACoin/BLE_LED_strip
this one, took me little time to figure out how to use wireshark, get data, input command with my phone...eventually the voltage regulator died a day after for overcurrent or dead chip. But it was fun. I don't have the motivation to undead the device unfortunatly.

#219Last weekend, I decided to take a step to learn and build things, it is also a way to learn about LLM, in which I ended built InkChatGPT. A small and simple RAG LLM app that with tons of learning resources that I was afraid to start to learn with.
I've been diving into the world of Large Language Models (LLMs), particularly the Retrieval Augmented Generation (RAG) approach. As a learning project, I built InkChatGPT, an AI agent that can assist with learning from multiple documents through a chat interface, inspired by projects like ChatPDF.
Under the hood, I used LangChain as the LLM framework to simplify the backend, Streamlit for the front-end UI and deployment, and OpenAI's `gpt-3.5-turbo` model. For generating embeddings for document chunking, I leveraged HuggingFace's `all-MiniLM-L6-v2` model.
Coming from a mobile development background, delving into ML, LLMs, prompt tuning, and various techniques has been an eye-opening experience. While the wealth of information can be overwhelming, building projects like InkChatGPT has been an incredible learning journey.
I'd love to hear your thoughts and experiences with LLMs and RAG systems. Feel free to check out the InkChatGPT repo [1] and share your feedback.

#220A 15-minute-city analyser using OSM data. You gave it a list of everything you wanted to be close to (ie a school, restaurant, doctors office, food store etc.) and it would show you which parts of a given city had all those things with an N minute walk.
Fascist! How dare you suggest I shouldn't ever go further than 15 minutes to access necessary resources to live my life! It's my god given right to spend at least an hour in traffic to get to the doctors... /s there is actually a whole movement of people in the UK that beleive the very idea of a 15 minute city is a conspiracy to limit their freedoms...
That’s hardly a fair characterization.
The problem is simply one of putting the cart before the horse. Most people simply can’t afford to live within a 15 minute walk of a doctor’s office and there is no real plan in place to fix that.
