Ask HN: What are you working on? (August 2026)
Replaypics allows a person to create an event and upload pictures, optionally invite others to upload their pictures. It selects the best and makes 4 collages and 2 videos (portrait and landscape). The videos are set to music that is selected as per the mood of the photos, cuts synced to the beats.
Trying a different monetisation method: Albums are free to create, users pay only to get the share link. Curious whether people will pay at the share moment.
It's also an attempt to make use of LLMs as not primarily chat partners. Keen for feedback if any of this strikes you as interesting
I love the hardware because it's the only keyboard I've been able to find that keeps a live Bluetooth connection and lets you toggle back and forth between USB and Bluetooth instantly using only a keyboard shortcut. That means you use two computers, and switch back and forth as fast as you can type. Years ago I also added a feature that changes the backlight color based on the active connection, so you can instantly tell which computer your typing will go to. I haven't been able to find any other keyboard that's quite as nice.
Lately I've spent weeks using an LLM to update the extremely old keyboard firmware to the latest firmware of its components (e.g., Circuitpython, the BLE firmware, the boot loader) and implementing all of my dream keyboard features that I never had the gumption to spend hours implementing pre-LLM. I finally resolved years-old bugs, and I added things like layer-based backlighting (so that the individual keys with relevant functions are lit), a better battery gauge, better sleep/suspend timing, backlight calibration, better debounce, and so on.
I've also upgraded the hardware and added batteries to each of the keyboards (I have three of these, one at home, one in the office, and one for travel).
It has been a very satisfying project, finally scratching a years-old itch.
Most of my time lately has gone into Flippd, its successor, which we recently soft-launched. We’ve also released a tech demo that uses custom computer-vision models to identify a pinball machine from a photo and extract the player’s score.
You can try it here: https://flippd.gg/scan
It will have all the top word games in one place with more coming over time.
I always wanted to build games, and AI finally made it possible for us to move fast across UI, level design, coding, and even video production.

How I created a golf dispersion pattern generator -- which I made open source -- so that it can be improved, because the golf analytic companies already have the data and almost certainly won't share it: https://golfcoursewiki.substack.com/p/how-to-bake-a-dispersi...
The tunnel itself worked, but stock illumos could not manage the DHCPv6 prefix delegation required by my connection. I also spent quite a bit of time tracing a four byte ABI mismatch between a 64 bit Rust process and a 32 bit illumos service.
There was no happy ending, but I learned more about the illumos network stack and distilled the experience into a blog post: https://skalski.dev/connecting-my-illumos-box-to-a-japanese-...
You can work on shared files instantly without uploading or downloading them.

Since last month hardened bidirectional edits such that people can work on video assets with Premier Pro, DaVinci, and such.
Got a pre-alpha release, where we managed to split congestion control over QUIC and bulk data transfers over TCP, and the lockless conflict resolution :D
