What are you working on? Any new ideas that you're thinking about?

I've spent a few months building a simple feature management system for .NET - https://featureflags.app. The .NET built in feature management libraries work pretty well. But I wanted an easy to use UI for configuring flags - without having to use Azure.

This month I worked on my own AI agent written in POSIX shell. It's been surprisingly useful for debugging command line problems on an old laptop running linux, like fixing an apt problem.

A graphviz dot substitute in pure rust:

Things I missed in original graphviz dot:
1. predictable / stable layout
2. dark and light mode css (tailwind)
3. interactive through pure css
4. markdown descriptions

When I switched from engineering to product, I tried a bunch of different user insight tools. They all had their strengths and weaknesses, but they always felt... off. They gathered feedback well but it wasn't easy to answer the questions I was asking, and it was a huge chore to keep it organized.
So I hacked on https://inputbuffer.io and just opened it to a wider audience.
You hook up your user feedback source (via widget or API) and it will organize everything by content category (e.g. billing) or target (e.g. a specific page, API endpoint, CLI command etc).
Categorization isn't rigid, InputBuffer does its best to put feedback where it belongs and gives you a clear triage flow if you want the added control.
Once organized you can learn more via a quick analytics dashboard or by interrogating the data directly, chatting with InputBuffer to gain a stronger understanding of your product, with clear citations to all feedback.
I have had success on both small and large amounts of input, on traditional SaaS platforms, developer tools, open source projects and more.
Next up: automatically gathering user input from other platforms (like GitHub issues), and more research tools.
I am working on a reddit lead generator that pings you when someone wants a product like yours in real time, and It does so only when the intent is high.
Was using this only for my self, but i think it might be interesting for other people as well.

Still working on https://compears.shop we’ve added some new features to help people shop in the EU for cheap. I’m hoping we get to expand this to more EU countries
I _just_ published https://klar.im/ a local-first AI spam filter for Apple Mail on mac.
It is build using a model that can classify messages (ham/spam/marketing), packaged for Apple Mail but could be used in other places.
I have been working on a AI native browser = WebMCP is first class and the in-app agent uses it to do tasks.. not the same as a slapped on chat sidebar. also MCP actions are lightning fast.. so i use it via my Hermes agent.

apt-cacher-ultra: To help reduce the impact of future DDoSes of Ubuntu. Just released 1.0 yesterday after working on it a couple months.
As that DDoS was going on I realized that some of our dev and staging processes were impacted by it, and that apt-cacher-ng was doing nothing to help us.
apt-cacher-ultra snapshots the repo meta-data after verifying it, and only promotes it if the metadata all checks out. Additionally, it can optionally keep a list of "hot" packages, and can include those in the snapshot calculation.
Additionally, apt-cacher-ng would regularly choke and require some handholding. I'm hoping -ultra resolves that as well.

I have always wanted a web browser with tmux/iterm2 style tabs/panes, as well as the ability to save the window configuration and tab contents to a file that can be checked in to projects and loaded.
Load all of your project's documentation links, local development browser tools (database viewers, etc.) into a set of views that can be source controlled with the project. Don't force people to use their daily driver browsers for this, or hack side-by-side views together with their OS window managers. Zen and friends have split panes, but it's not the robust tab/panel system that I wanted.
There is a simple tab widget system, which so far has:
- Viewport manager: basically 1:1 with what is in Chrome devtools
- Session manager: create and manage browser sessions as a first-class entity, and attach/detach tabs to these sessions. Includes a simple "incognito" toggle as well.
- System light/dark override: stop flipping this on/off for your whole OS to test "system" light/dark mode (tedious)
- Reload trigger: pick a target tab. if that tab reloads, so does this one.
- Log file viewer: if the tab source is a local file, change the tab's view to a structured log file parser with search/filter, play/pause, etc.
- Screenshot/Video capture: not built yet. pretty self explanatory.
Great keyboard controls are a hard requirement for me. It's a little tricky since content in web views can capture this too, so I have a global "nav mode toggle" you enter to move around between panes and the tabs within them. Actively figuring out the correct UX, but I am liking what I have so far.
Toying with the idea of a "tab link" which allows you to store a set of "source" tabs in a view, but create "links" in other views, where the navigation is synced across all instances. Useful if you want to have, say, the Tailwind docs open to a specific page, but have that page shared across different views. For example, if you want to have one view specifically for mobile view work and another for desktop view work, and not have to manually navigate to the same Tailwind docs page in both views.
I'm honestly just using it as I work on another real project, and adding features as I think "hey wouldn't this be nice?" Which is a pretty fun and satisfying process. I don't have it published yet, because I'm not entirely sure if it's worth sharing at the moment, but I feel like I'll discover that along the way here and go from there. Maybe someone here will chime in :P
I am working on a local first LLM frontend that saves all chats directly to your hard drive and ships in a single index.html file artifact that you can self host.
No code to show yet. I'm taking the time it requires.
I struggle with terminology so I made a little Gnome utility for easier LLM-based terminology lookups from a highlighted word/term + contextual screenshot. So far it's working pretty well, kinda like a better version of the Mac OS or Kindle ones.

A powershell-like objects-over-text UNIX shell in Lisp. I’m afraid it’s another agentic turd I produced, but I’m polishing this turd a lot more than the others.
Code World Models in Simultaneous Move settings like Capital Markets. DeepMind's CWM approach relies on standard MCTS/IS-MCTS, which assumes a single active player at each node.
This doesn't work in simultaneous-move settings like Orbit Wars (or order-book markets), converging to an exploitable pure strategy rather than a Nash equilibrium.
LeCun's JEPA, by contrast, is a learned neural world model, which lacks the determinism, speed, and debuggability of a code-based simulator. Thus, it can drift or predict illegal states, and you can't inspect why it made a prediction the way you can trace a Python function.
TL;DR: The benefit is better auditability and easier RL-like training. The SM-MCTS extension fixes the first problem (decoupled UCB per player approximates Nash equilibrium instead of a pure strategy) while keeping the second advantage intact (a deterministic, inspectable code simulator).

It's a coding harness that eschews autonomy and instead works like a pair programming partner, with distinct "driver" and "navigator" modes. I've only spent 3 weekends on it so far, so it's a long way from finished. But I am at least using opair to work on opair now, which is nice.
I didn't really want to write a harness, I just got frustrated enough that nobody else was writing the harness I actually want to use. I'll probably be the only person that uses this, but I'm fine with that.

There are many like it. This one is ours.

Here's what I _wish_ someone was working on, I'd build it myself but I'm too busy with other projects. A browser extension that's not a popup blocker but a popup minimizer. So any popup (newsletter, cookie notification, even social signin) gets sucked down into a Windows 95 style taskbar. You can restore them easily but they get out of your main browsing flow. Maybe start as a fork of one of the popup blockers?
i make the microsoft word but less sucks, and there is scientific calculator integrated and also ai on it too, available on linux (stable) and windous (unstable).
