Ask HN: What are you working on (September 2025)?
What are you working on in September 2025?
In the last month or so I've been solely focused on plans and content for my instance for my local town, so there hasn't been any programming for a little while but I'll be jumping back into it in weeks to come.
- The idea: https://carlnewton.github.io/posts/location-based-social-net...
- A build update and plan: https://carlnewton.github.io/posts/building-habitat/
- The repository: https://github.com/carlnewton/habitat
- The project board: https://github.com/users/carlnewton/projects/2
I think the biggest hurdle for this would be to gain traffic in place of an existing entrenched local Facebook group or similar.
I've helped a friend get an IFR/Aeroflex/Marconi 2947A Communications Analyzer working, and am now in the process of using Ghidra to disassemble the firmware that runs on the main CPU. (There are several, including a 68000 based cellular option). I think of it as a million piece jigsaw puzzle.
On the way to Vintage Computer Fest, MidWest, my car became the middle of a 5 car sandwich. We all walked away, thanks to modern crumple zones and restraint systems. So, the car is a total loss, now I'm filing forms, and will be looking for a replacement car.
Happy lets you spawn and control multiple Codex/Claude Code sessions in parallel. Happy Coder runs on your hardware, works from your phone and desktop, costs nothing, End to End encrypted, and permissive MIT License.
https://github.com/slopus/happy
Happy Coder is a unix style "do one thing well" project.
The goal is zero workflow disruption. I want to be able to run CLI coding agents on any internet connected computer, and control them with my phone. Happy has a command line wrapper for Codex and Claude Code that let you start a session in your terminal, and then continue it from your phone with real time sync. So type in your terminal and see it on the phone, type into your phone and see it in your terminal. So you can switch back and forth.
There is an optional voice agent some contributors have been hacking on that lets you talk to the voice agent first, and the voice agent then writes prompts for Codex/Claude Code and answers questions about what the coding agent running on your computer is doing/did. The voice agent feature is pretty neat, but in my opinion needs a bit more iteration, so any ideas or help would be awesome.
Each issue includes: - Featured talks of the week highlighting the must-watch talks of the week. It includes a short human-written video summary. - New talks including the complete list of all the talks that have been uploaded in the past week. These are grouped by conference and ordered by view count.
From time to time, I build talk compilations, for example: - https://www.techtalksweekly.io/p/50-most-watched-software-en... - https://www.techtalksweekly.io/p/100-most-watched-software-e..., which made it to the HN front page.
Later on, I find myself switching between Claude, Cursor, Codex and Gemini-cli. (Not much gemini-cli to be honest:D ) And wanted to play with MCP Servers, so I built Roundtable https://askbudi.ai/roundtable , and when I face a bug, or I need to brainstorm, I task it to create subagents from Claude, Codex,... And task each of them to analyze the issue and then aggregate their opinion. It is fun, and I feel I get more out of what I have already paid for. ( Paid for Cursor 1-year plan, later on switched to Claude Code, and codex is a part of the Plus plan that I have access to)
Currently working on supporting batch favicon requests that bundle multiple URLs in a single image sprite.
It started out as a Spotify oriented project but due to their recent API changes[2] I ended up focusing more on a Last FM integration. This wasn't that bad as their API provides more details such as play count per song. I've also added an Apple Music integration.
I posted about it[3] on Last FM's subreddit and I was pleasantly surprised to see that a lot of people shared their labels on the comments and seemed to like it.
I'm currently working on language detection, I think it'd be cool to get a language breakdown of the songs you listen to and for that to be part of the displayed items within the label. Something along the lines of EN- 80%, ES- 15%, FR - 5%
I've also tried getting Adsense on the website but I keep getting denied on "Low Content Value" grounds. I tried some alternatives but the quality of their ads was ridiculous (stuff like "your device has a virus, click here to clean it up")

Android and iOS are in a working beta, might do a web front end eventually too.
I'm not a professional at any of this (accounting day job) and there has been a lot of learning but in the end, what a trip, I made a software! I've had a ton of help to bring it to life from a friend who is an actual professional at the back-end stuff (thanks Balthromaw) and copilot too.
I am going to try vibe coding this one, simply because I know how to do the job but don't feel like doing it.
I wanted the power of spaced repetition, the frictionless experience of social media, and the joy of a beautifully designed application.
It’s built and I’ve been using it daily for about 8 months now, and lately it’s been working remarkably well. I’m learning several languages, and dabbling in even more, all in just an hour a day.
Now I just have to get all the marketing assets up and marketing it. Working on a new landing page at https://phrasing.app/next — not at all ready to be shared but the question is what am I working on!

The concept is pretty simple: It takes screenshots every few minutes and reconstructs a calendar of what actually happened. On top of that features to set goals for how much time to spend on topics and a social feed.
This is obviously super sensitive data. I built it in a way that it never stores raw data and you can also bring your own Gemini key, plus a lot more privacy features. Tried to make it fully local but found that it takes too much energy and only works on high end machines.
I have a few first users, iterating with them, and right now exploring if it’s possible to make this work in team settings without sacrificing privacy.
"Overcentric is like Google Analytics + Mixpanel + Hotjar + Intercom, in a single, cohesive, clutter-free package." - as one of the users described it.
Our vision is for Overcentric to work on autopilot: integrate it in minutes and it works around the clock to understand, support and empower your users - so you get the relevant insights on how to grow and retain more users.
I also had an idea that it would be good to have a "what-if" product that could simulate financial aspects of life.
Do you have a demo?
Now exploring on extending this to general programming languages. Software is getting increasingly complex, but I don't think we have figured out many ways of navigating large codebases. Would love to hear about your favourite tools in this space and what would you like to see?
I’m looking for a remote role where I can apply this hands-on experience with Full Stack engineering and AI agent orchestration to real-world production environments.
Unsure what the plan is going forward with it, apart from adding more venues and more countries. As long as it's fun for me I'll just keep going, but it does probably need a differentiator to be interesting.
Consider placing link to the catalog/places right on the main page, otherwise it is not that intuitive to discover where it is!
The data is initially crowd sourced, or researched by me when I'm bored. Keeping things updated is done with various automated (and some manual) alive checks for each venue.
I know you're right about the landing page. Would be nice to show the closest venues or locations there immediately, but I absolutely loathe pages that ask for positional data right off the bat (could do some geoip stuff maybe).

It stated as a bit of a toy but we've got 200 people signed up to the waiting list, so we're doing a kickstarter in November!
Mostly targeted to sales platforms and tools, but getting some early interest from individual GTM teams and agencies as well.
Attracting new monthly sponsors and people willing to buy me the occasional pizza with my poor HTML skills.
- Google Form UI customizer https://customgform.com/
My toolset: nextjs, drizzle orm, postgress, shadcn, tailwind.
Host this on VPS on digital ocean, using traefik.
Do you have any use cases?
What was the reason to start this project?
2). Use cases where you can use it are different: e.g support form, early access, feedback form, events...
3). Reason to start: I wanted to have the ability to add a form to website within minutes, for free and without any backend work. Google form suite best here, they act as backend. The customgform provide only UI layer, which sends data directly to Google Form.
Currently working on a better CodeOwners for GitHub.
It would help coordinate multiple security detectors and map outputs to frameworks.
