Hi all,

I just got a Raspberry Pi 5 and I'm about to do my first setup, but it's a jungle to understand everything as a 'noob'.

My plan is to install the following:

• Pi-hole
• Tailscale
• Traefik

I want to achieve DNS ad blocking and access to all my services on my laptop and phone.

Would these services achieve this? Do they work together? And am I missing something to make it work?

Sorry if this is plain stupid to ask, but I can't seem to find anything where all 3 is used together.

In a new study, the scientists show that their synthetic melanin, mimicking the natural melanin in human skin, can be applied topically to injured skin, where it accelerates wound healing. These effects occur both in the skin itself and systemically in the body.

When applied in a cream, the synthetic melanin can protect skin from sun exposure and heals skin injured by sun damage or chemical burns, the scientists said. The technology works by scavenging free radicals, which are produced by injured skin such as a sunburn. Left unchecked, free radical activity damages cells and ultimately may result in skin aging and skin cancer.

Let's hope this can be in production in the coming years as this really could help people in many ways.

Read the link for a pretty good ELI5 to understand what melanin does and why it works.

The EU has announced €4bn (£3.4bn) of state aid investments in new factories producing electric batteries for cars, heat pumps and solar panels as it seeks to accelerate production and the uptake of green technologies and combat cheap Chinese imports.

The Swedish battery producer Northvolt will receive €902m in state aid to build a new factory in Heide in Germany, while a wide range of clean tech factories in France are to get a €2.5bn bump in state aid.

Following the discovery of the rock, Jan Christian Vestre, Norway’s minister of trade and industry, said Norway had an “obligation” to develop “the world’s most sustainable mineral industry”.

Once mined, the ore can be processed into phosphoric acid and supply a broad range of uses, including lithium-iron-phosphate batteries and animal feed.

“When you find something of that magnitude in Europe, which is larger than all the other sources we know - it is significant,” founder and deputy CEO of Norge Mining, Michael Wurmser told news website Euractiv.

"We believe the phosphorus that we can produce will be important to the West - it provides autonomy," he continued.

However, the refining of phosphorus has historically been very carbon intensive, which is partly why there has been little production in Europe in recent years.

Norge Mining plans to use carbon capture and storage to offset the environmental impact of production, though the efficacy of these technologies is often calle

And this is net emissions reductions, also taking into account the emissions from extra electricity generation.

Still a long way to go. The world still uses more oil each year, but new technology is certainly helping in lowering that curve.

I recommend to read the whole article for more information and what we can expect in the future.

Food experts from Queen Margaret University (QMU) in Edinburgh, Scotland, have cooked up a substitute for one of the world’s most environmentally contentious ingredients: palm oil.

They’re calling the breakthrough innovation PALM-AT, and say the plant-based discovery is healthier for both people and the planet.

It has 88 per cent less saturated fat and comes with – they say – 70 per cent lower emissions than regular palm oil, which is used in everything from baked goods to toothpaste to cosmetics.

Developed using linseed and rapeseed combined with fibre, it can be made locally on a global scale, avoiding the deforestation and habitat loss associated with palm oil production in countries including Malaysia and Indonesia.

Donanemab and Lecanemab work by clearing the amyloid protein that builds up in the brains of people with Alzheimer’s. Trials suggest they can slow cognitive decline, but not halt the disease. The drugs – set for UK approval in 2024 – mark a turning point in treating a disease that is expected to affect 1.7m Britons by 2040.

“We’re now on the cusp of a first generation of treatments for Alzheimer’s, something that many thought impossible only a decade ago,” said Dr Susan Kohlhaas, executive director of research at Alzheimer’s Research UK. “People should be really encouraged by this news.”

Alot of businesses are starting to prioritise sustainability as it's what the customers want.

Vote with your wallet, if you can.

EDIT: Thank you so much everyone! There's so much help for me here, and I'll recommend anyone with similar question as me to read the comments

Basically title.

I have the DVDs and I have the hardware to burn them to my PC.

But the file size is too much. What software would be ideal to get the best quality with the lowest file size?

I'm going for file sizes per movie at around 2-3gb max.

For me it's the Batteries Regulations.

It includes things like:

• Replaceable batteries that is "easy for consumers to remove/replace" in devices like smartphones, tablets and cameras by 2027.
• Recycling "of critical raw materials such as cobalt, lithium and nickel" in batteries will be prioritised and developed further by 2025.

Let me hear yours. It can be anything, and also regulations from the past which came into effect in 2023.

First of all, L4s (sorry misspelled in titel) is not a real user, so no harm done here.

It's an automatic bot xposting from reddit, making this community just as bad as r/technology, which kind frankly only revolves around politics and social media platforms.

I've had the user blocked 2 weeks now, and this community is muuuuch more enjoyable and is actually about technology now.

Just wanted to share a positive experience.

Alot of us who have a Raspberry Pi 3 or 4 might upgrade to the Raspberry Pi 5.

Doing so would leave us with 2 Pi's. What are some great use cases for the older Pi, that would no longer be the main machine?

EDIT: Thanks so much guys! This was really helpful, and I didn't imagine so many would help out!

Hey guys,

I've used PiHole for over a year now, and I really like it. I use it with WireGuard, so I always have my DNS blocker with me.

But I've wondered if I even have some good lists? I used some standard lists from a reddit thread when I set up my PiHole, and I've never looked at it since.

So what blocklists do you use? Something you can recommend?

Also, if you use Blocky or AdGuard, do you find it better than PiHole?
