Discogs alternative

Is there an alternative to Discogs for cataloguing physical music media? My specific problem is that I cannot add a certain bootleg record to my collection, even though I can find it in the Discogs database. I suspect this is due to the transaction-focused nature of Discogs and enshittification.

Si tenemos una duda se la preguntamos a la IA, la IA, entrenada por humanos, nos dará una respuesta (probablemente equivocada) ¿Por qué no nos consultamos directamente entre personas?

Creo que la utilidad de la IA está en analizar muchísimos datos y dar valoraciones estadísticas en base a patrones. Más allá, la encuentro innecesaria. No entiendo por qué hay que pagar a una empresa para que nos dé información, cuando podríamos consultar directamente con la persona que tiene la información de primera mano.
Antes de esta locura de la IA, propuse a una gran empresa la creación de una app que sirviera para poder consultar con un experto en cualquier área, porque todos somos expertos en algo. Los usuarios se registraban también como expertos y tenía un sistema de puntos que permitía que los mejores expertos pudieran ganar dinero con sus consejos, así como la participación de empresas. Yo creo que con la publicidad adecuada hubiera sido un éxito. La empresa nunca contestó, ahora tienen una IA para dar el conocimiento humano bajo pago. Sigo pensando que no les necesitamos, que los humanos ya podemos traspasar nuestro conocimiento directamente y que cada una se nosotros podríamos tener una agenda de contactos inabarcable. Y esto no le gusta a las empresas.

I Want to Make the Most Beautiful, Aesthetic, Free and Open-source Platform for Learning Japanese Ever

The idea is actually quite simple. As a Japanese learner and a coder, I've always wanted there to be an open-source, 100% free for learning Japanese, similar to Monkeytype in the typing community.

Unfortunately, pretty much all language learning apps are closed-sourced and paid these days, and the ones that are free have unfortunately been abandoned.

But of course, just creating yet another language learning app was not enough - there has to be a unique selling point. And then I thought to myself: why not make it crazy and do what no other language learning app ever did by adding a gazillion different color themes and fonts, to really hit it home and honor the app's original inspiration, Monkeytype?

And so I did. Now, I'm looking to find contributors and testers for the early stages of the app.

Why? Because weebs and otakus deserve to have a 100% free, beautiful, quality language learning app too！

CaddyManager 0.0.2 - SQLite is here! - Web UI for managing Caddy servers

Hey everyone! I couldn't have imagined people so eagerly jumping on the first release of CaddyManager, thank you for all the feedback and with that I have shifted instantly on putting SQLite in place ;) Looking forward to hearing how everyone is liking it, please don't hesitate to put feature requests in so I can build out a bit of a bigger roadmap!

Here's update 0.0.2!

This release has a set of quality of life updates that will hopefully greatly improve everyone's experience with CaddyManager, thank you all for playing around with it thus far! This release introduces multi-database engine support, with SQLite as default, this did mean that the docker compose has changed. I also made some changes to backend/frontend communication so it becomes significantly easier to reverse proxy the app. (literally just a reverse_proxy rule to the frontend)

New features

\- Multi-database engine support, with SQLite as default and MongoDB as alternative option

\- Alternative JSON editor for bigger changes and copy/pasting

\- Initial dashboard setup, will be improved upon in the future, as well as Open Telemetry integration.

Improvements

\- Improved all input fields readability

\- Frontend container is now properly communicating directly with the backend, clients dont need to interact directly with backend anymore

\- When using domains that already exist in a config, combined with a template, the merging with the existing configuration doesn't break the Caddy config anymore

\- Improved logging and added various cleanups throughout the codebase to improve speed

Please note that the compose file has changed!
You can find the last version here: https://github.com/caddymanager/caddymanager/blob/0.0.2/docker-compose.yml and in the readme of course!

When you find a bug, please use Github issues to report it!

My Open Source Captive Information Portal - Make one yourself!

Hey everyone,

I'm into DIY electronics and a firm believer in using tech for community organizing and resistance. I’ve been working on a project that flips the concept of a malicious captive portal upside down. Instead of stealing info, this device gives it away, completely offline.

You’ve probably seen those WiFi “login” portals at airports or cafes. You know, they’re used for logins into a public WiFi, and sometimes created to steal credentials by nefarious actors or joksters using Bruce Firmware, etc. (not what we are doing here, but often a DIY Electronics project which is easily available online). I flipped the idea into a form of resistance...

I wanted to figure out a way to distribute information in a way that is discrete and fully offline, that allows access for anyone to whatever valuable information you want to put out there. So, rather than making a fake wifi to capture credentials, I made this repo, which creates a fake "wifi" network and a captive portal. However, when you join it, rather than bringing up a login page, it can bring up a fully offline HTML-based web page full of information. I created a version regarding techno-fascism and what we can do to fight back, like practicing media discernment and active community building, amongst other things.

I know this idea of a captive portal webpage is not new, but I wanted to make it accessible to anyone who would like to make one of these little info drops, and a version that wasn't just for pranks or malicious credential capturing.

The minimum needed components are an \~$2 ESP32-C3 or another microcontroller and some way to power it, like a small power bank. I chose the ESP32-C3 Super Mini as it's barely an inch square and can be easily hidden, but you could change the config for practically any microcontroller. I've also included code to add a very cheap LDR sensor (Light detector), so if you want to try to deploy these using a battery and solar, it can detect when it's dark out and go into a deep sleep. This way, it is only active when most people will be around during daylight hours and conserves battery at night. You can easily make one of these little devices for under $5 to carry around with you, or with a few more bucks, make them practically an indefinitely available source of information using a battery and solar power.

Some other use cases might be:

\\- Spreading public health information.

\\- Spreading banned or suppressed information.

\\- Providing information during protests or other gatherings that can not be disrupted easily, since this device does not use the internet.

\\- Providing information to the unhoused, such as addresses and information regarding locally available resources.

Many features could make this even better, like being able to update the data hosted on them from afar, etc. They could probably even be used with LoRa to make a sort of resistance message board that is only in a community (depending, I guess, on how many people create nodes)

This is a fully open-source project, so feel free to contribute if you have ideas! I've included some example HTML and information in the examples folder under docs. Maybe we can make a few more examples to add to the Repo for those who'd like to make one!

Would love to hear what you all think! Cheers!

RPi4 as alternative to Chromecast

Hi,

Not sure if this is the right place. Sorry if this is simple, I couldn't find anything online.

I was investigating whether its possible to use my RPi4 as a replacement for my audio and video Chromecast. Preferably 2 in 1 where I can select the output. And I want to be able to control it with my phone.

I was hoping there is already something similar or maybe parts that I can combine. Please let me know!

What I was thinking is something like the following. But I'm happy to hear other ideas.

RPi4 connected to both my stereo and TV (and allow for more). With maybe a simple yml/json for some settings. And some small tool to enable/disable output channels.

Then I have 2 options:

Either SSH or remote desktop and just play everything from there and use the tool to select the output. Very simple, but not very user friendly.

OR

Have a webapp which you can access when you connect to my WiFi. In that webapp you can select the output. And then select what you want to play. Either by simply copying the URL or (and this would be nicier) by having a browser in that webapp.

BEEP-8: An open-source Fantasy Console you can run in your browser

Hey folks,

Just wanted to share a project I think is fun from an open-source perspective: BEEP-8.

It’s a Fantasy Console inspired by retro hardware, but everything runs entirely in the browser using JavaScript + WebGL.

Highlights:

Free and open-source SDK on GitHub
Emulated ARM v4a CPU @ 4 MHz with 1 MB RAM / 1 MB ROM
WebGL PPU for sprites, BG layers, and simple polygons
Namco C30–style APU emulated in JavaScript
Ships with a lightweight RTOS for threading & IRQs
Works on both desktop and smartphones, locked 60 fps

👉 GitHub: https://github.com/beep8/beep8-sdk

👉 Try live: https://beep8.org

It’s more of a playful project than a serious platform, but I think it shows how open-source can capture the spirit of old hardware in a modern, accessible way.
