So, Telegram has launched horrible ads that look a lot like spam to me. At least in my channels it's typically some crypto bullshit. So, I wonder if people know about alternatives to the subscription service for blocking them? Sadly, Forkgram won't offer that option and it doesn't seem to be allowed. However, I wonder if there are still forks out there which block the ads? Or do people know of alternative options?

Inspired by this Mastodon account, I programmed an ESP8266 microcontroller to act as a traffic light, indicating the current electricity mix. Check it out on Codeberg! It uses an API from the Fraunhofer Institute and the parts cost around 5€. In my shared flat we use it as an indicator on when to run demanding devices, like the washing machine.

So let's assume that there was an easy way to make a sustainable investment by investing into a great fond. So in this hypothetical fond only shares from truly great companies exist. Why should this make sense from a sustainability perspective? Unless the companies in that fond are selling their shares for the first time, the company won't ever see any benefit from me investing, will it? The invested money only gets passed to the person who held the shares before me. So I really don't understand why all the resources I could find stressed how great it is to invest sustainable and what a good impact one has. Am I missing something here? And, a bit offtopic, do you have an idea how to use the money so that it actually does some good?

So currently I use Grapher for plotting equations. I've used it for years and it works great, but it doesn't seem to be open source. So I looked for a FOSS alternative, but didn't find one on F-Droid or the rest of the internet. Do you know of a FOSS alternative? What do you use? Do you prefer web applications (like Wolfram Alpha)?

I first heard about I2P here on lemmy. The concept sounds really cool, but does anyone actually use it? And if so, what for? To me it sounds like it depends on many people using it and many applications integrating it, which just doesn't seem to be the case.

Does anyone know of a FOSS app for yoga practice? This seems easy enough, but I couldn't find anything on F-Droid...

Ok please don't be offended, I'm just innocently unknowing and only recently started identifying as something like enby transfem. But what is the meaning of the blåhajs? Why does a (admittably cute) plush Ikea shark have such relevance here? And can you maybe also enlighten me about common pitfalls I should avoid? (Like a wrong model, wrong spelling, wrong way of cuddling, ...) Or how strict are the blåhaj expectations there? Thanks <3
