I built a reverse proxy similar to Cloudflare Tunnels that can be self-hosted: https://tunlr.dev This came about because of how awkward Cloudflare Tunnels is to use in a development environment.

#262I'm building CAIL – an AI that makes and answers phone calls for you. You type what needs to be done – it calls, talks, waits on hold, asks questions, and sends you a summary. Kind of like a voice assistant, but for actual phone calls. Also built an AI voicemail agent – it can answer missed or declined calls, figure out what they wanted, book a meeting in your free calendar slot, or even mess with spammers if needed.…
I do however think people would be more tolerant of an AI answering a phone call they made, I'm bullish on that half of the equation.

#263So I’ve been building my own YouTube app, for my own kids. Better blocking of keywords (no more 1,000 MrBeast video recommendations). Better educational themes.
Email me if you’re interested in testing.

#265To start with, there's https://nuenki.app. It's a browser extension that selectively translates sentences into the language you're learning, so you're constantly immersing yourself in text at your knowledge level.
I've also been working with a friend on a device to help blind people without light perception. I'm quite new to electronics. It's pretty simple, conceptually - a coin-sized device on the forehead that takes in the light intensity in a ~15 degree cone, then translates it into high resolution haptic feedback to the forehead.
The idea being that it means people without light perception can gain a sixth sense through neuroplasticity, with helps them navigate the room and understand their surroundings. We're planning on open sourcing the files. My mum used to teach blind kids, and there's been quite a lot of interest!
As for Nuenki, I'm pretty bad at marketing, so I'm doing a final lot of work to see if I can make it work financially - seeing if an exceptionally generous affiliate program will do the trick - before putting it on maintenance mode, since I have a small group of users who really like it. I'm burning through my gap year fast, and really want to focus on the electronics project, tutoring, and practicing maths for my physics degree.

#266Most language apps make you select whole words rather than type, so I made an app that focuses on text first
It's helped me find the letters on the keyboard much quicker and rattle off common responses
Check it out! Would love your feedback

#268- Build dependency graph from dependency pairs.
- Generate the topological sort from the graph.
- Ordered parallel task sets (i.e. subsets of nodes that can run in parallel, within the overall topological order).
- Cycle detection and reporting the cyclical nodes.

It's feature complete, but I still have problem publishing it as a library. Kept getting "unable to find module 'toposort'" error when importing it in a separate project.
Edit: Alright, finally figured out why the module was not published. The default project creation template in Zig 15 uses createModule() in the generated build.zig, which creates a private module. Switched to use addModule() to create a public module and my library can be imported and used by other projects.

#270vimgolf.ai
Right now, only has two levels but I soon plan to add all the Vim motions and use reasoning models as bots that start off the level with you. Apparently, reasoning models like o3-high, Claude 3.7 thinking, and Gemini 2.5 pro are good at finding new ways to transform files using Vim. Kind of silly to have them do that, but I find it kind of cool.
