Farmers that combine grazing land with solar farms (badass name incoming: agrovolatics) are seeing 2-3x income to traditional farming.

So i'm doing a bit of reading about the basics of nuclear fission these days, just to understand what's actually happening there.

Here are some interesting things that i think that i learned so far:³

• nuclear engineering is all about the neutron economy. If you had an easily-available cheap source of neutrons, we wouldn't need big nuclear power plants because energy could be easily generated by hitting Hydrogen-1 (protium) with neutrons to make H-2 (deuterium) out of it. According to this diagram, this releases around 2 MeV of energy per collision (resulting nucleus has 2 nucleons), which is a lot of energy.

• the problem is that we don't have a cheap source of neutrons, and that's about where the whole trouble with nuclear energy begins. we're smashing U-235 specifically because it's fissile and can sustain a chain reaction: It emits more neutrons per collision than it absorbs, so we get a net gain of neutrons out of it.

• the sun sources its neutrons from weak interaction between protons and electrons¹. Basically this fuses a proton and an electron together to make a neutron. This is the rate-limiting factor in the sun's fusion and determines the sun's lifetime before it burns through its fuel. The average time for a particle to undergo weak interaction is about 10¹⁰ years in the sun's interior which is about the sun's lifetime. If the sun had more neutrons, it would burn faster.²

[1]: well, sorta. this is kinda simplified and more precisely described in the proton-proton chain which is the same thing but with extra frills.

[2]: Also note that while the weak interaction is the rate-limiting factor of the fusion process, it barely releases any energy. Almost all of the energy is released due to the strong interaction which glues protons and neutrons together really tightly and that way releases a lot of energy.

[3]: if you know better, please do correct me.

Weeks before introducing a bill to streamline data center development across Pennsylvania, [Republican] State Sen. Greg Rothman’s real estate firm quietly collected a fee from the $30 million sale of land now hosting the state’s largest proposed data center. Whether that sequence amounts to a conflict of interest — or simply an uncomfortable overlap — depends entirely on who you ask and what standard you think elected officials should be held to.

Most people have no idea of the work that wildlife carers do. These are volunteers that give an enormous amount of their time, care and money to rescuing and rehabilitating our injured and orphaned native animals.

This article gives a pretty good description with a lot of photos. I hope you enjoy it.

Jay encourages people to support their local wildlife rescue group, ensuring donations directly assist the volunteers caring for wildlife in their own communities.

Infineon Technologies has opened its Smart Power Fab in Dresden, Germany, months ahead of schedule, bringing the world’s largest manufacturing facility for intelligent power semiconductors and analog/mixed-signal technologies into operation.

The facility represents a €5 billion (about $5.7 billion) investment, the largest in the company’s history. It creates 1,000 direct jobs and doubles Infineon’s manufacturing capacity in Dresden.

The factory will produce chips that improve how electricity is converted and managed. Those devices will support AI data centers. They will also help power electricity grids and software-defined vehicles.

Can we deny that putting messages on missiles is legally a meme now? We obviously cannot. Thank you for the assenting nods. Take care.

Seriously, weekly I restart the laptop to clear out the cache and ram and whatnot and from restart to launch then opening chrome it's like a hot minute tops. Meanwhile back on my old hdd laptop a restart was a 10-15 min affair.

Hello.

Ive been using CloudStream for the last little while but my kids find it a little clunky.

I've installed Stremio today but am not clear as to how to tee it up with free pirate streams, ala CloudStream.

I've checked fmhy and the glanced at the mega thread, as well as asking my clankers.

Can someone point me in the direction of the equivalent of CloudStream's Mega plug in / repository for stremio?

EDIT: thank you to all. All the solutions you suggested worked, but in the end, it was just eaiest to pay for Real-Debrid.

On July 4, 2025, roughly a dozen people participated in a demonstration at the Prairieland Detention Center, a facility serving Immigration and Customs Enforcement. At the conclusion of the demonstration, a participant named Benjamin Song saw a police officer aim a gun at a participant named Nathan Baumann and fired warning shots at the ground in response. Since then, police have arrested 22 people on widely publicized conspiracy and terrorism charges, subjecting many of them to long-term solitary confinement and other pressure tactics. The first eight of the 17 non-cooperating defendants went to trial in March; they were found guilty and sentenced to between 30 and 100 years in prison each, with one of them receiving a 30-year sentence simply for having moved a box of zines.
