What are you working on? Any new ideas that you're thinking about?
Comments
Public dataset for exploring 50,000+ 401(k) plans holding $7.5T in assets.
You can look inside a company like Google and see what employees invest in (mostly 2035-2055 target date funds) or how much they contribute ($30K - likely using Mega Backdoor Roth)
Recently have been focusing on a personal assistant type of thing.
I've been building it with the agent sdk and any time I want an additional skill, I create it
Examples: parse this pdf containing my credit card bill and add all transactions
Given it has a db, I've been using it to save notes, ideas etc.
Been fun
DTAP protocol.
Double TAP is lightweight testing framework where users write black box tests as rules checking output from tested "boxes". Boxes could be anything from http client, web server to messages in syslog. This universal approach allows to test anything with just dropping text rules describing system behavior in black box manner.
building a GPS tracker for my cats who like to wander outside.
some features:
- no monthly subscriptions
- location via GPS/GNSS
- a screen that hangs on my fridge (akin to marauders map, to see where the cats are at all times)
- the location data stays local always.
The tech will be extended to more products - a watch for adults, kids tracker etc. Will release here once I have all the tests completed!
Building some prototypes around the Recursive Language Model paper. I'm currently working on integrating it with Unity for scene and script automation. Thinking about standardized patterns for retrofitting this into other existing business systems. If I can make it drive Unity reasonably well, I think it could drive a lot of things.
During the holidays, I’ve experimented with some ideas. I wondered if it was possible to make money in 2025 using simple, nano banana wrappers, thr answer is yes!
for example, RecolorLife.com and Headshoti.com generate around $800 USD.
Now I will expand for real estate.
Two weekend projects:
- https://github.com/rcarmo/gotel (an OpenTelemetry tracing collector/UI, under heavy refactoring)
- https://github.com/rcarmo/toadbox (a simple Docker-based agent sandbox to run Toad/OpenCode/Mistral inside, which I've been cleaning up for general use)
Multiple things, but among many:
- A sports club management platform, and a way for end-users to sign up for sports events, lessons etc.: https://mojtim.ba/en/
- Given the raise of AI, I'm a hiking guide and would like to have that as an alternative, an outdoor activity agency - https://boa.ba (still very WIP)
Been hacking on https://rsolv.dev. It's a security scanner with a couple of unique twists; in addition to using AST validation to cut the false positive rate, it uses a heavily orchestrated LLM to write unit tests that fail if the detected vulnerability is present.
Happy for alpha users; it's really early days right now. Email in profile if you want to give it a try at no cost.
I’m working on a startup that aims to make decarbonisation profitable faster, based on the following idea:

I'm working on The Influencer AI(www.theinfluencer.ai), a platform that lets you create realistic and consistent AI personas('ai influencers') to use on social media or as your brand ambassador. You can use this unique AI person in photos and talking videos, for use cases like talking about your product, creating a high quality Instagram persona, photos for your e-commerce site, etc.
A Substack for 80/20 life advice that gets repeated every year. We all know what to do, the idea of this is to remind us every week of one aspect of life and what best practices are for that area.

Tried to do this as low tech as possible, so website is just an off the shelf notion wrapper
Locque is a language designed to both be easy for LLMs to read and write, but also for humans to review, and it's designed along my philosophy that the more structure you can give coding agents, the better, so it's dependently typed and hosted on Haskell at the moment. Feedback eagerly solicited.
My Friend and I are working on Fostrom: https://fostrom.io
It's an IoT Cloud Platform built for developers. We're still in technical preview and are currently working on adding more telemetry to our small device agent written in Rust.
Check out our docs at: https://fostrom.io/docs/
Still working on my new LPFM radio station https://www.kpbj.fm
We are a 501c(3) and are actively fundraising to build a tower here in Shadow Hills and are launching our live stream and regular schedule February 1st. So far we have about 60 shows in the schedule.
If you're in Los Angeles and have an interest in radio, please hit me up.
Been working on a Google-sheet backed workout tracker, which basically makes it easy for me to see what I've done or not done recently and pick the next thing to do. I'm thinking of open sourcing this soon, but need to do some "de-monolithing" first.
I finally decided to promote my gitignore pattern Python library, pathspec, from v0.x to v1 after 12 years or so.
I'm thinking of reviving my Python SQL parser prototype I have half done. Or maybe resume my Mako template plugin for PyCharm.
I am working on version 6 of the Nutrisense. A device to keep track of what you eat (calories/protein, etc.) without the need to type it in, in some app.

My Family recently (in the last couple of years) started to breed Ragdoll cats in the U.K.
In an attempt to support what's involved in this I built Ardent for them. It covers a bunch of the day-to-day concerns (weighing and health tracking), Lineage and Inbreeding prevention, and Owner Pack generation for handovers to new Owners.
https://interviewcop.com - interview cheating affects both businesses and legit candidates like myself.
I'm trying to solve this problem with AI agents that help interviewers to understand who actually can code and understand the code they're presenting.
I am working on a camera module that has SLAM built-in: https://x.com/_asadmemon/status/1989417143398797424
Running on a single-core armv7. It includes a VIO and a nice loop closure. I am now optimizing it further to see if I can fit some basic mapping too.
Still working on PocketWise (https://pocketwise.app), a simple double-entry accounting app. Just finished adding end-to-end encryption with a zero-trust server model. All encryption and decryption happens in the browser (using PRF), and the server only sees encrypted data.
I'm building a web-based local multiplayer party game platform. It's like a lovechild of Jackbox Games and Mario Party: https://gamingcouch.com. Back in December Gaming Couch hit the front page of Hacker News, you can check it out here: https://news.ycombinator.com/item?id=46344573
The TL;DR:
- Currently in free Early Access with 18 competitive mini-games.
- Players use their mobile phones as controllers (you can use game pads as well!)
- Everything is completely web-based, no downloads or installs are necessary to play
- All games support up to 8 players at a time and are action based, with quick ~one minute rounds to keep a good pace. This means there are no language based trivia or asynchronous games!
- In the future the plan is to open up the platform for 3rd party developers (and Gamejams!) as well. We'd take care of the network connectivity, controllers etc.. 3rd party devs can focus on developing cool multiplayer mini-games without spending an eternity with networking code and building the infrastructure.
TCKR - Scrolling Stock LED Ticker for Windows https://github.com/krypdoh/TCKR
I've been working on this for several weeks/months and I'm happy with the result!
Vibe coded it as my programming skills have eroded with time (or they never existed).
I would really appreciate some feedback.
I'm still working on my Web Server Library .NET Core
I'm rewriting from scratch : https://simplew.net/v26/
"Hold for Me": uses LLM to detect when somebody picks up your call https://github.com/predkambrij/Hold-for-Me-using-ADB
Building Cassette: a dead-simple computer in the cloud: https://cassette.sh
One always-on Linux box to run apps, databases, CI, and AI agents without hyperscale complexity, surprise bills, or Kubernetes. AI-driven app explosion plus mature open-source deploy tools make simple servers fast, cheap, and fun again.
I'm working on Narwhal, a pub/sub protocol and server specifically designed for edge applications. The protocol can be extended via an external component, and the product is completely free and open source: https://github.com/narwhal-io/narwhal
The easiest and simplest calorie counter
Writing a WebAssembly module parser from scratch, focusing on good diagnostics/errors and DX.
Currently it's fully-conformant to v2.0 of the spec, while I'm working towards implementing the recently released 3.0 version.
Continuing to build GhanaHousePlanner https://ghanahouseplanner.com/, currently focused on enhancing the cost accuracy and constraint solver for the generated house floorplans.
I'm building https://swishfinance.app - minimalistic and simple stock widgets for your PC. That way I no longer have to make a conscious effort to check my portfolio — it's just there on my desktop.

I’m a remote dev building an iOS app called Springus. You add a few pics / your closet basics, and it suggests outfits based on what you already own. It’s less “fashion app” and more “tiny morning momentum hack.”
Would love feedback from other WFH folks — a weird amount of my productivity comes down to how I start the day.
I am super curious about tensor parallelism and the mechanisms behind how some models can activate only some of their attentions.
Platform for apps, currently Lua support ( future WASM). Think like apk (android app) but spk.zip that has server.lua file for backend and htmt/js/css that get served for front end plus platform gives Files, SQLite db (namespaced/scopped access ), Auth, User management All in single static binary Cz go
Edit: formatting
I have been working on the next generation of Canva and Photoshop for highly regulated verticals where there are specific demands placed on the generation and edit flow.
If you are a brand who needs to deploy advertisements at scale, don't hesitate to reach out.
meta-analysis, make Claude write a blog post, connecting and deriving set of concepts across a range of books, articles, papers, etc. Basically a syntopic reading machine. Its a meaty side project (and expensive), but I am curious how close I can push this. My current approach relies on a tool that I have built recently [0], it's an agentic memory but I am using a new memory model that is based on Zettelkasten principles.
What is really cool about it is that it natively capture connections between atomic ideas and evolve them. Which I believe it gets me one step closer to syntopic reading machine.
I am working on SIP4AI [1] (a VOIP soft-phone where AI is on the other end, not a human). You can self-host it, register a SIP line, and let AI take the calls.
It works with your existing phone system, so you can just add AI as a line without having to replace everything…
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 should build”, but as an exploration of trade-offs.
Some hard lessons I learned along the way: Complexity vs. Performance: … The "Memory Shock": … (idle baseline; load benchmarks still in progress) Over-engineering: …
I'm currently squashing the final bugs…
I'd love to hear from senior folks here: …
https://sendbroadcast.net - I've been working on it since October 2024, and it's still going strong.
Currently on v1, but working on v2 release in the next month.
I’m working on agent-os: a slf-hosted web UI for managing multiple AI coding CLI sessions (Claude Code, Codex, OpenCode) with multi-pane terminals. All free and open source: https://github.com/saadnvd1/agent-os
Working on a job board as a service. [1] I'm hoping that communities, bloggers, or newsletters pick it up to monetize their audience.

I am working on an failure proof introduction to Lisp/Scheme for imperative programmers. I always thought there was something unapproachable about Lisp. But I finally figured it out, and I want to document my path for people like me. It's going to be great. Expect to be done in a week or so!
A personal agentic tool for action cam video editing. When I moto / ski / bike, I leave my helmet cam rolling the entire time. It takes a very long time to 1. find scenes and 2. edit them down into a reel or video. It works well for my amateur use case - basic edits with only cuts and transitions.
https://fuzzygraph.com - aspires to be the most beautiful equation graphing app
I've been experimenting (over 130 test batches so far) with creating an all-purpose balm (lip, hands... stuff).
I wanted something more useful to carry than typical gooey lips balm full of petroleum and silicone.
I'm working on a cozy animal sanctuary game in Godot. Having used Unity and Monogame only in the past, Godot has been a lot of fun and easy to use.
