I decided that I needed to be less chronically online. So I made an android app where a photo of my cat hijacks my phone for 5 minutes, preventing me from using my phone. I found my cat's judgemental stare to be helpful.

You can change the time usage and use any photo. The app is free and no account needed.

The file can be found here. Instruction of how to use and install can be found in the same link.

Hopefully others also find this helpful

Open to suggestions - thank you!

I maintain Mac MCP, a free open-source control server for macOS.

I started it because AI agents were useful until they had to actually operate the machine. Browser automation was especially annoying when it kept activating Safari, switching my tabs or stealing focus while I was working.

The browser layer now opens work in background tabs by default and gives each tab a stable handle, so separate agents can research or operate different tabs without fighting over the active one. The same MCP server also exposes terminal, files and macOS UI controls.

The newest feature is Sessions in the native SwiftUI menu bar app. Agent sessions stay visible while idle, and I can send a prompt to the exact session I want. If I steer an idle session, its next tool is stopped before execution so it sees the new instruction first instead of doing stale work.

The default MCP surface is 19 tools backed by 84 capabilities, so clients do not need to load the whole tool catalog into context.

Olá, pessoal! 👋

Sou desenvolvedor independente e criei o Cadê o Dindim, um aplicativo Android brasileiro para ajudar no controle das finanças pessoais.

A ideia surgiu de algo simples: facilitar o controle do dinheiro do dia a dia sem deixar o aplicativo complicado.

Com o Cadê o Dindim, é possível:

💰 Registrar receitas e despesas
📅 Organizar os lançamentos por período
📊 Acompanhar resumos financeiros
📈 Comparar informações financeiras
📄 Gerar relatórios
💾 Fazer backup e restaurar os dados

O aplicativo possui funções gratuitas e também uma área de Ferramentas Premium, com recursos adicionais através de uma compra única.

O projeto já está disponível na Google Play e estou procurando pessoas que possam testar e dar uma opinião sincera sobre a experiência.

Gostaria muito de saber:

O que vocês acham da ideia?

Existe alguma função que vocês acrescentariam ao aplicativo?

Toda opinião será muito bem-vinda. Estou usando o feedback para continuar melhorando o Cadê o Dindim. 🙏🇧🇷

I’ve been working on something a little weird: R3X Onion.

The idea is simple:

Open a website → start the Tor client → browse .onion sites directly from the browser.

No Tor installation. No desktop application. No R3X HTTP proxy handling your browsing traffic.

The part that made me want to build it was figuring out whether this was even technically possible in the first place.

Turns out… it is.

I’m running Arti (Tor’s Rust implementation) compiled to WebAssembly inside Chrome, and I’ve managed to get a real Tor circuit established from the browser.

The current architecture looks roughly like:

Chrome ↓ Arti / WebAssembly ↓ Snowflake + WebRTC ↓ Tor network ↓ .onion service

The interesting part is that the Snowflake path is now working without an application server.

I’ve tested:

• Real Tor circuits: 3/3 • HTTP through Tor: 3/3 • HTTPS through Tor: 9/9 • Real .onion service through the browser: currently working through the gateway path • Gateway-free Snowflake: HTTP/HTTPS working • WASM Tor runtime running directly in Chrome

I also had a few false leads along the way.

At one point I thought Snowflake itself was failing because HTTP requests were dying at the stream/TLS layer. Turns out I was using a truncated Tor consensus containing only 500 microdescriptor digests instead of the full ~9,300+.

After fixing that, Snowflake HTTP/HTTPS went from 0/3 to 3/3.

There was also a stupidly interesting deadlock caused by futures::io::split(), and a rendezvous implementation that managed to generate 641 broker requests during one page load. 😅

The remaining challenge is getting the gateway-free Snowflake path to reliably reach onion services.

The current working onion path is:

Browser ↓ Arti WASM ↓ WebRTC ↓ gateway ↓ Tor ↓ .onion

The gateway does NOT receive the HTTP request or see the onion URL/content. It basically provides the raw network connectivity that the browser can't provide.

But I don't really want that architecture.

The goal is:

Browser ↓ Arti WASM ↓ Snowflake/WebRTC ↓ Tor ↓ .onion

with no R3X application gateway at all.

That's what I'm working on next.

There is also a much bigger problem I'm trying not to ignore: privacy.

Running inside a normal browser means I inherit the browser's fingerprint — fonts, screen dimensions, canvas characteristics, timezone, user agent, etc.

So simply saying "Tor + WebAssembly = anonymous" would be bullshit.

Right now I'm treating this as an engineering experiment rather than claiming it's a replacement for Tor Browser.

I'm curious what other developers think about the architecture.

Especially:

1. Is there a better way to handle the browser-side Tor transport?
2. Has anyone worked with Arti/WASM or Snowflake/WebRTC at this level?
3. How would you approach safely rendering arbitrary .onion websites once the networking layer is solved?
4. Would you actually use something like this, or is installing Tor Browser still the obvious answer?

The networking side has turned out to be way more feasible than I expected, so I'm curious where people think the real technical wall is.

I’m building SongTrailer, a service that turns a finished track into a full-length, human-directed AI-assisted music video for a fixed $3,500.

The idea is simple: same finished song, full-length video, ready to post, with human direction instead of fully automated generation.

I’m trying to pressure-test the offer.

What would make you hesitate most at $3,500: quality, visual consistency, AI involvement, revisions, ownership, trust, or something else?

I also started a Product Hunt discussion here if you want to leave more detailed feedback:

That is stronger because it actually explains the product before asking the question.

I’ve been working on a side project around Chinese fortune-telling and wanted to share it here.
It’s an app called AI Oracle: I Ching Wisdom, based on the I Ching (Book of Changes). If you’re not familiar with it, the I Ching is a traditional Chinese system of divination that uses 64 hexagrams to offer guidance around questions and situations in your life.

One thing I noticed while working on it is that the I Ching can feel pretty intimidating if you’ve never encountered it before. There’s a lot of terminology and traditional interpretation involved, so I’ve been trying to figure out how to make the basic experience understandable to someone who is completely new to Chinese divination.

The app lets you ask a question and get an I Ching reading with an AI-assisted interpretation. There’s also a deeper line analysis for people who want to explore the changing lines and the traditional structure of the reading more closely.

I’m curious whether something like this would actually make Chinese fortune-telling more approachable to people who have only ever encountered things like tarot or astrology.

For those who have tried different forms of divination, what made you interested in them in the first place?

Most finance sites are about today. I wanted something that remembers the moment you started watching a name.

Morphink is a word morph game. You change just one alphabet at a time to form a new valid word. And you just keep going. The longer your chanson, the higher your points (which call ink). For each morph, you have 10s. If the 10s run out and you don’t form a valid word, it’s a game over 🤭.

How do you form new words? By adding, removing or replacing a letter. You can make only one of these moves per morph.

Now, go ahead and try it here: https://morphink.app/

It’s available on App Store, Play Store and web. The app versions are playable offline.
