  • And things like vertical bifacial solar panels can work especially amazingly on grazing land that isn’t suitable for crops.

    Counter-intuitive as they may look, they actually have a number of benefits:

    1. The panels face east and west, meaning they generate peak power in the morning and evening, which corresponds to peak demand => less need for energy storage to bridge the gap between the mid-day peak in production from traditional PV and the aforementioned morning and evening demand peaks.
    2. The panels are vertical, which makes them easier and cheaper to maintain, as dust, snow, and rain naturally shed from their surfaces.
    3. The panels get less direct energy during mid-day, keeping their surfaces cooler. Turns out cooler solar panels are more efficient at converting light energy into electrical energy.
    4. The arrangement lends itself very naturally to agrivoltaics, which means you can derive more yields from a given piece of land and use less land overall than if you had segregated uses.
    5. The compatibility with agrivoltaics allows farmers to diversify their incomes streams and/or become energy self-sufficient.


  • Silvopasture is an ancient practice that integrates trees and pasture into a single system for raising livestock. Pastures with trees sequester five to 10 times as much carbon as those of the same size that are treeless while maintaining or increasing productivity and providing a suite of additional benefits. Livestock continue to emit the greenhouse gases methane and nitrous oxide, but these are more than offset by carbon sequestration, at least until soil carbon saturation is achieved.

    Silvopasture also offer financial benefits for farmers and ranchers. Livestock, trees, and other forest products, such as nuts, fruit, and mushrooms, generate income on different time horizons. And help protect farmers from risk. The health and productivity of both animals and the land improve.

    Trees in silvopasture systems provide livestock with protection from sun and wind, which can increase animal comfort and improve production. Trees can provide shade in the summer and windbreaks in the winter, allowing livestock to moderate their own temperature. Heat stress in livestock has been associated with decreased feed intake, increased water intake, and negative effects on production, reproductive health, milk yields, fitness, and longevity.[4][5]

    Certain tree types can also serve as fodder for livestock. Trees may produce fruit or nuts that can be eaten by livestock while still on the tree or after they have fallen. The leaves of trees may serve as forage as well, and silvopasture managers can utilize trees as forage by felling the tree so that it can be eaten by livestock, or by using coppicing or pollarding to encourage leaf growth where it is accessible to livestock.[1]

    Well-managed silvopasture systems can produce as much forage as open-pasture systems under favorable circumstances. Silvopasture systems have also been observed to produce forage of higher nutritive quality than non-silvopasture forage under certain conditions. Increased forage availability has been observed in silvopasture systems compared to open-pasture systems under drought conditions, where the combination of shade from trees and water uptake from tree roots may reduce drought impacts.[1]

  • The raison d’être for RISC-V is domain-specific architecture. Currently, computational demands are growing exponentially (especially with AI), but Moore’s Law is ending, which means we can no longer meet our computational demands by scaling single-core speed on general-purpose CPUs. Instead, we are needing to create custom architectures for handling particular computational loads to eke out more performance. Things like NPUs, TPUs, etc.

    The trouble is designing and producing these domain-specific architectures is expensive af, especially given the closed-source nature of computer hardware at the moment. And all that time, effort, and money just to produce a niche chip used for a niche application? The economics don’t economic.

    But with an open ISA like RISC-V, it’s both possible and legal to do things like create an open-source chip design and put it on GitHub. In fact, several of those exist already. This significantly lowers the costs of designing domain-specific architectures, as you can now just fork an existing chip and make some domain-specific modifications/additions. A great example of this is PERCIVAL: Open-Source Posit RISC-V Core with Quire Capability. You could clone their repo and spin up their custom RISC-V posit chip on an FPGA today if you wanted to.







  • Exactly. When the accused has paid off half the jury, you shouldn’t put much stock in the verdict.

    The only thing I care about when determining whether something is a genocide is the facts of the case (which are overwhelmingly in favor of describing the Uyghur genocide as a genocide), not the outcome of a highly political vote by countries all with their own motives and interests.











  • Sounds similar to some of the research my sister has done in her PhD so far. As I understand, she had a bunch of snapshots of proteins from a cryo electron microscope, but these snapshots are 2D. She used ML to construct 3D shapes of different types of proteins. And finding the shape of a protein is important because the shape defines the function. It’s crazy stuff that would be ludicrously difficult and time-consuming to try to do manually.

    It’s funny how people always use play it like “oh, it’s just differing opinions” when what they’re actually defending is indefensible malarkey like nazis and tankies. They know if they made a meme saying we should “try to understand” nazis and tankies, they’d be downvoted to oblivion. And so they hide behind a shield of “differing opinions”.

    These cretins have a right to post nazi and tankie shit on their own instances – them’s the beauty of the fediverse. But I also have a right to not want hate speech, genocide denial, and Hitler/Stalin/Mao simps polluting my feed. It’s not mere “differing opinions” when one person’s opinion is “Holodomor didn’t happen, and if it did, the Ukrainians deserved it” or “Holocaust didn’t happen, and if it did, the Jews deserved it” or whatever apologia they wanna peddle.
