I am overengineering a simulation-based solution to this because I think there are scenarios based on cup shapes and environmental temperatures that allow either answer to be true. This will end up as a blog post I guess.

#473Working on a original algorithm to explain human behavior from 3rd person perspective (1st stage). The whole research is divided into 6 stages. In 2nd stage, I will mathematically establish the best course of action as an individual given the base theory. In 3rd stage, I will explain common psychological phenomenon through the theory, things like narcissism, anxiety, self-doubt, how to forgive others, etc. In 4th sta…

#474It looks inside each file to see what it’s about, then moves it to the right folder for you.
Everything happens on your Mac, so nothing leaves your computer. No clouds, no servers.
It already works with PDFs, ePubs, text, Markdown, and many other file types. Next I’m adding Microsoft Office and iWork support.
If you have messy folders anywhere on your Mac, Fallinorg can help.

#476I'm currently building my own coding agent, VT Code. VT Code is a Rust-based terminal coding agent with semantic code intelligence via Tree-sitter (parsers for Rust, Python, JavaScript/TypeScript, Go, Java) and ast-grep (structural pattern matching and refactoring). It supports multiple LLM providers: OpenAI, Anthropic, xAI, DeepSeek, Gemini, OpenRouter, Z.AI, Moonshot AI, all with automatic failover, prompt caching,…
I love that you've made it open source and that it's in Rust, thanks a lot for the work!

#478The first is a DNS blocker called Quietnet - https://quietnet.app. Its born out of my interest in infrastructure and I wanted to build an opininated DNS blocker that helps mom and pops be safer on the Internet. At the end of the day its just the typical Pi-hole on the Cloud but with my personal interest in providing stronger privacy for our users while keeping their families safe.
The second, is a small newsletter aggregator tool called Newsletters.love - https://newsletters.love/.
I wanted to create a way for people to start curating their own list of newsletters and then sharing them with their friends and families. The service helps to generate a private email adddress that they can use to subscribe to newsletters and then start reading those newsletters whenever they want without it getting lost in their email inbox.

#480I've been suffering from migraines for the last month, so have channeled my (non-migraine) time into a migraine tracker to try and find the root causes. All the tracking apps I tried all have nice complex forms, which is all well and good, unless...you are having a migraine. Rough idea is easy to use voice mode to record data, then analyze unstructured data with AI later on. I want to track all relevant life informat…
