A TUI to monitor your OpenAI and Anthropic usage inside your terminal.

https://github.com/htin1/toktop

I use codex and claude code daily, also build apps with openai and anthropic api keys, so i always go to openai dashboard and anthropic dashboard to track my usage. Since I spend most of times inside cursor or terminal, I wanted to quickly check my usage without leaving my terminal/ide, so i built this!

It's open-source, MIT, and built with ratatui (awesome name).

Still very focused on making light healthier. 3 new products:

Bedtime Bulb v2[0]: A massive improvement over our original Bedtime Bulb, a light bulb meant for use in the evening to reduce blue light. The headline feature is the re-introduction of infrared, which was removed from lighting to make it more efficient, but emerging research suggest it's beneficial for health. After a long wait, this is shipping in 2 weeks!

Atmos Bedside Lamp[1]: A fully automated circadian lamp that automatically shifts in color and brightness throughout the day, helping you prepare for sleep and wake up more naturally. Working on some machine learning features that mimic the functionality of the Nest Learning Thermostat, but for lighting. The first units are shipping by Christmas.

Circadian Mode for Philips Hue[2]: A web app that gives your Philips Hue lights circadian powers, so that they gradually shift from bright light during the day to dim, low-blue light at night. It's way more powerful and easier to use than first- and third-party options from Hue, Apple, and Home Assistant. Just launched this week; looking for beta testers to give feedback!

I work on Robotics, so was recently implementing slamkit in rust. https://github.com/MostlyKIGuess/slam-rs

But a lot of what I work on is my classes giving me less time to open source nowadays, but I have also worked in implementing and mashing new Papers coming out in Robotics. Anyone who wants to talk more should please connect!

About 2 years back I began working on a very simple markdown compiler, it was “immediate” in that it would consume markdown and immediately spit html. That project turned into a whole static site generator called Kevlar — https://github.com/aadv1k/kevlar

Entirely built from scratch in C without any dependencies. Now I wrote this code when I was 16, so many memory leaks and generally issues that I wanted to rectify and begin using third project for my own blog (currently old version is used — https://aadvikpandey.com)

The Kevlar v3 (https://github.com/aadv1k/kevlar/tree/kevlar-v3) here is all that it includes; more spec compliant markdown AST-based parsing; A better .ini config parser (right now it’s literally strtok on ‘=‘ and generally very hacky) as well as name spacing; more powerful templating tags like IF, FOR with lisp-like configuration

Of course staying true to the spirit of “from scratch” :)

Honestly I did scope creeped a little since I mainly wanted to fix a memory leaks issue in the markdown compiler lol; anyway I will share it once it gets completed on hacker news :)

I have always wanted to learn Rust, but was too distracted to get started.

So, I started working with Claude on building a postgres database replication application. I'm learning Postgres internals as well as how brittle database replication and subscription can really be. Although this is for Seren, you can replicate between any PG databases. https://github.com/serenorg/postgres-seren-replicator

Big learning: Claude Sonnet with Rust is massively productive. I'm impressed, but code bloat is a thing.

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 experimental features like annotations, questions, etc.

I hope this service might be useful to others as well. You can sign up with github account to submit your articles as well. I would appreciate any feedback.
