  • As i understand it it (somewhere between barely and not at all) the idea is not that It’s “expanding” in the sense of a balloon inflating into the space around it.
    Its more stretching internally.

    So the distance (or time it would take at constant speed) between any 2 points is geting bigger.
    You could maybe also say it’d take more energy to move between the points in a set time.

    There’s probably nothing outside, but the distances inside get longer.

    It’s probably something to go with gravity, momentum and entropy. The actual concept of “distance” between things might not be what we think.

    But all these theories give rise to the concet of large amounts ob unobserved ‘dark’ mattter and evergy, so the actual basis of currently observable fact (i.e. energy / mass) is a small fraction of what is needed for these theories to work.





  • 22 ft unsupported seems like a very long span to me, what’s that nearly 7 metres?
    Sounds like it’s getting into the realm of structural enginneering not diy for me.

    If you want to save costs you might think aout a “flitch beam”, that’s 2 wood beams with a steel plate sandwiched in between - the three components are bolted together every few feet. Easier to join to the timbers then.

    I still think you might be more like 10"x2 or even 12"x2 timbers to cover that span if totally unsupported. But might still come in a little cheaper than the i-beam.
    Maybe the roof will be very lightweight and no snow weight is expected - but I’m no structural engineer so don’t take my word for it.

    Other features like corner bracing or canti-leverage, or some other support structure or other feature (like is it the bottom side of a framed gable triangle) might also help.

    LVLmight not be suitable, but i think you can get treated “glulam” beams suitable for exterior (covered) use.

  • It’s a donation so you’re never going to have perfect pricing everything down to the nearest penny or remunerating each person-hour worked. I think It’s about something rough and ready that is better than nothing. And it’s all goverened by morality anyway . . .
    so doomed to failure on that side.

    Buy hypothetically a simple principle with reasonable administration cost, like each 3 months, each node shoud add up all donations, slice off 25-50% , split it equally among their top 5 or 10 most important dependencies - just guess, and maybe swap from quarter to quarter if if there’s doubt. There’s some wiggle room there for small projects to do less and large over funded projects to do more.

    Each node in the network could follow a simple rule like that, making a limited number of transactions each time period ,and you’d probably end up with quite a complex outcome after a few iterations (years).

    The real trick would be having enough nodes in the network that actually enact such a simple rule. (Apart from having enough donations flow in to the consumer level projects of course).
    But enough nodes and enough inflow and the fractal would work for you - roughly.

    THe speed is an issue, the more often you settle up then quicker people see money, but the more the admin cost.
    But even doing it quaterly is not slower than doing nothing.

    Such a model is not something anyone will be securing bank loans off though, so if that’s the point then you probably need a paid licensing / service model of some sourt maybe Canonical and redhat.







  • I’d guess they’d need to figure out whatever apple did with it’s arm chips.
    efficient use of many-cores and probably some fancy caching arrangement.

    It’ll may also be a matter of financing to be able to afford (compete with intel, apple, amd, nvidia) to book the most advanced manufacturing for decent sized batches of more complex chips.

    Once they have proven reliable core/chip designs , supporting more products and a growing market share, I imagine more financing doors will open.

    I’d guess risc-v is mostly financed by industry consortia maybe involving some governments so it might not be about investor finance, but these funders will want to see progress towards their goals. If most of them want replacements for embedded low power arm chips, that’s what they’re going to prioritise over consumer / powerful standalone workstations.
