Ask HN: What are you working on? (February 2025)

I'm working on a SaaS that will detect publicly shared AWS resources. Not by evaluating policies but by actually testing the availability. Some examples: can a KMS key be used from a 3rd party AWS account, are there any object in an S3 truly exposed publicly, and similar. The motivation is to find truly critical issues in AWS account setup by addressing the first priority items - public exposure.

Another project that is currently only happening in my head - I am thinking about security operations teams that I think often do the same things in different companies. Namely there is a lot of tinkering with detections and alerting, often for the same services. I think this could be cost optimized by being offered as a SaaS.

I'm creating a infinite canvas that has all your organization's code and documentation on it. If you zoom in, you can see the code, if you zoom out you see the big picture. By giving everything a place on the map, it becomes easier to figure out your way through the landscape and understand the systems. Different modes can you show you different things: code age, authorship (bus-factor, is the person still with the company etc), languages used, security issues. There's time-travel, think Gource for all software in your company, and maybe the most fun: a GeoGuessr for code. Select e.g. the repos for your team, you get a snippet and have to guess where it is. The plan is for LLMs + tree-sitter to analyze all the code and show relations to other systems, databases etc.

I had the idea 2 years ago, but starting building in earnest 2 months ago. Spending all my time on it now, minus 3 or 4 days per week of earning money. Currently looking for a GTM/sales-oriented cofounder in NL.

In between figuring out what to do after a decade of work on Micro (https://github.com/micro), I started a new project called Reminder which tries to provide a single clean app and API for the Quran, Hadith and names of Allah. Maybe some of you would find it beneficial. It tries to put English first since most of us are non Arabic speaking and cultural from the west.

I’m currently developing a link-in-bio tool that requires no cookies, no trackers, and no signups—a true “privacy-first” approach. I’m building it with lovable, which has really helped me overcome the fine-tuning and bug-fixing procrastination that used to slow down my projects.

After spending a lot of time in an acquired startup and becoming more specialized in my role, I realized I needed to switch back to “build mode.” It’s been a rewarding exercise to try generating some organic traffic (no-ads by design) and a much needed escape from excel sheets.

Wondering if being still on a third level domain is messing up my SEO efforts.

I've been working on an iOS app that aggregates cinema showtimes across chains and independent theaters in the UK.

I moved to London some years back, and was pleasantly surprised by the vibrant cinema scene, that seems to be in a steep decline in so many places. On any day of the week, one can find independent films, old and new classics, Q&A's with filmmakers etc. playing in one of the many theaters across the city. Staying on top of it all is a chore though, and I found myself missing out on screenings regularly, because I didn't check that one cinema's website on time.

This is also my first time building and releasing an independent app. The journey from research, backend development and learning SwiftUI has been a trip. Released on TestFlight a couple of weeks ago.

I recently made a little tool for people interested in running local LLMs to figure out if their hardware is able to run an LLM in GPU memory.

I live next to a school, so there's a low speed limit (30 km/h). Still, people drive like race drivers and the city hasn't ever responded to the residents' hopes of introducing a speed camera.

I wanted to have some data on how many people speed, the max speed recorded, that sort of thing. Things the city should be doing after many complaints of dangerous driving and people being almost killed on zebra crossings.

I have a doorbell camera, and by analysing the footage using OpenCV and some code, I can track how fast people drive if you see how fast they move between two known points.

Average speed: 46 km/h :(

I've been working on language for a little over a year now. There's no documentation at all, just some examples if you can figure out how to run them. I thought building a compiler would take less time than it has, but it's been feeling like a good investment in my future of making things. It's a project I can just keep moving with forever.

Continued working with my team to grow my granddaughter who at 15 months handles a spoon and fork to feed herself at each meal; drinks from a cup without assistance; can clean her face and understand everything she is told or asked (though sometimes with a devious smile makes what an adult might consider a poor choice.... She is testing her boundaries like she is supposed to do). I have learned how to and produced 6 different embroidery patterns on various pieces of infant clothing. I combined multiple web based directions to create a Wi-Fi enabled USB (from a raspberry pi W 2) to enable a link from my computer to my embroidery machine. I made cookies and shared them with others creating a lot of joy I'm visiting with my grandson in another state, modeling good parenting and offering help where I can.

Working on "wanting to live". It's hard to create desire within oneself when one has experienced intense sorrow.

Been trying the "do the thing, and desire comes after" for many things (baking, piano, skating, ..), but that hasn't really worked. What has seemed to work is connecting with people (crucial that they know how to connect back).

Made a little web app that helped me communicate: https://azriel.im/tears/

(I could just point to the number when I couldn't talk/listen)

I've working on Colanode, an open-source & local-first Slack and Notion alternative that you can self host. You can use Colanode for real-time chat, as a knowledge center, project management or file storage. As a local-first application, Colanode offers full offline support, allowing you to work even when you’re not connected to the internet or the server is not available. You can host it in any environment (with minimal dependencies), giving you full ownership and control over your data.

A simple, non tech method to increase agreement in online arguments.

I’ve gotten to some degree of a protocol, surprisingly.

I had made this LLM prompt (about a year ago?) wildly useful in helping me think.

It’s helped with everything from realizing you have burnout, relationship issues, arguments with family members, Mondays

I made another version, which showed its “thinking”.
