Anti-spam email/messaging protocol that is simple, cheap to implement, directly compatible with email/messengers, low false negative rate compared to current spam filtering, free for senders, and does not require the sender to pay to send a message. For people who receive too much marketing spam, survey spam, low-effort cold emails, and want to be able to easily filter spam successfully because you do not want to waste time on them.

Future-proofed and will work on AI spam in the future too, unlike current spam filtering methods.

I built a wireless highlights & annotations export service for Kobo e-readers earlier this year [1]. Had a free tier limited to 20 exports but wasn't sure how to price it beyond that, so I just left it. Recently a user reached out asking if I'd settled on pricing and how they could pay for unlimited exports! That jolted me into coming up with a price, and now I'm finally getting Stripe integrated :)

Making the Nest 2nd gen thermostat the Google recently bricked compatible with local setups like Home Assistant.

I'm involved in 3 projects that are solving this problem from different angles:

UI exploration for interacting with LLMs

Currently popular AI chat interfaces feel restrictive when exploring or learning complex concepts/ideas. I often want to revisit earlier parts of a conversation, ask branching follow up questions, connect related concepts, compare and contrast between various chain of thoughts. This UI exploration aims to solve some of these limitations.

I am currently working on a breastfeeding tracker for Garmin devices. It is already released a time ago, but I want to include a companion app for this app.

I used it with my first child, and it helped me greatly. After releasing the support has been amazing and I recently passed 1000 downloads :)

I am hoping to extend the functionality with more insights and helpful tips (double-checked with professionals) to help young parents with the beauty of breastfeeding their newborn children.

I recently became unemployed so I am building a tracker for all my job applications what stage I am at in each process that kinda thing

https://interviews.tools

It’s no where near done

But as always I am also building https://retro-board.it for doing retros and sprint poker

And https://flags.gg for feature flags with quite a lot of agents (rust, go, react, and others)

It may sound absurd: But a website in which people can set their availability on a calendar. Kinda like Doodle. My requirements are: - no account necessary - timezone support - not have to pay for it Basically impossible to find something which fills those requirements. So I am coding myself a handy tool. For what? To coordinate people for the game Foxhole to take responsibility for certain areas so we always have a General Manager online

I absolutely hate Doodles mobile UI, this would be great.

I'm going all in on my side project CodeBrew, a Java IDE for iPad. Currently working on OpenGL support for 3d graphics, as some schools requested the feature. Also I'm finally pitting some work into aquisition, which has turned out to be much more fun than I anticipated.

Go check it out, its free to try, with a one-time purchase full version:

I built an AI-powered voice agent to help people prepare for the IELTS english exam -- specifically the speaking portion.

https://ieltspal.ai

- Realistic exam conversations with natural follow-ups and questions to challenge your viewpoint

- Get scored on all 4 criteria (fluency, vocabulary, grammar, pronunciation)

- Instant feedback on where to improve

- Free credits to start

There are many existing resources to help prepare for the IELTS exam, however the options are very limited when it comes to practicing the speaking portion.
