Who do you think ruined Boeing?


Not stupid at all, that’s an excellent question! I’m not privy to the details of this furnace satellite but I have an idea or two on how I’d approach the problem. Pure (somewhat educated) speculation ahead.
Firstly, you mentioned nonconductive materials. Insulating material isn’t perfectly nonconductive but can get pretty close. I’d imagine combining insulation with the vacuum of space would limit conductive heat transfer between furnace and the other equipment.
Insulating and limiting the conductive transfer of heat doesn’t eliminate it though. You’d still need an active form of transfer to shed the heat. I’d investigate the feasibility of a convective heat exchanger; use coolant to transfer heat from the furnace to a radiator.
From there I’d study how the James Webb Space Telescope maintains equilibrium. It uses a reflective shade to shield the radiator from the sun but I lack specific knowledge of the design. The temperature difference between hot side and cold side is a driving factor in heat transfer; maximizing the difference between the two leads to more efficient, effective control.
Honestly though, its been a few years since my senior heat transfer course. Radiative heat transfer in the vacuum of space is Master’s if not PhD level specialization. I’m not at that level yet, so please take this answer with a large block of pink Himalayan salt.


Hah! My adoration of partial differential equations is far purer than even physicists could hope to achieve.


There are three modes of heat transfer; conduction, convection, and radiation.
Conduction happens when two bodies at different temperatures come into contact with each other. The total heat transfer depends primarily on the difference in temperature, contact surface area and time spent in contact.
Convection takes place when a fluid (I.e. a gas such as air or a liquid such as water) comes into contact with another body. Here, again, heat transfer depends on difference in temperature, contact (“wetted”) surface area and time in contact which is primarily dictated by how fast the fluid is moving over the body.
On Earth we generally leverage these two modes. An example of mixing the two modes is a CPU heatsink and fan setup. The heatsink conducts heat away from the CPU and is (usually) distributed throughout several extended surfaces I.e. fins. The fins increase the surface area in contact with air, enhancing the rate of heat transfer.
Now, we can’t really take advantage of those in space. The lack of an independent physical medium means the heat ultimately has no where to go; this is known as a “closed system”. So if we generate or store enough heat in a body subject to the void of space without promoting radiative heat transfer, that heat will more or less stay put.
Radiative heat transfer is fucked up. Everything above absolute zero radiates heat. You mostly can’t see this except for one glaringly obvious example; the Sun. Sol is so fucking hot that it heats the Earth through the vacuum of space purely via anger aka photons. And thanks to the miracle of science, you radiate anger right back at it.
Explaining radiative heat transfer further is outside the scope of this reply and will be left as an exercise to the reader.
I hope I explained this well enough for you or other readers to impart a ‘basic’ idea of a complex engineering discipline that I adore. I’m absolutely willing to answer any questions.


some truly world-shattering human-altering tech
Maybe say…climate change?


So really The Matrix should have taken place in a two dimensional world.
Alternatively, I would also accept renaming the trilogy to The Array, The Matrix, and The Tensor.


Disagree; the Patriot Act had plenty of easily determinable ways things could and did get worse.


Iftheycould st[w]ill get away with doing this to gays and blacksit would be happening to them instead.


With the word “Princess” spelled out in diamonds washed in the blood of African children!


At this point I’d nearly appreciate the removal of old.reddit or RES. My desktop browsing experience hasn’t changed in roughly a decade and a half and that’s a shitload of inertia. A few trims of my subscribed list has limited my exposure to the worst of the slop and botting.
Mobile is absolutely a different situation for both Reddit and Lemmy alike. I found Jerboa shortly after the API disaster and have stuck with it since, but I probably need to look into tweaks for desktop/browser Lemmy. RES and old.reddit are a killer combo but fuck their ‘official’ app and the ‘new’ interface.
Regardless, I no longer participate on Reddit and highly prefer interacting here; more interesting and informative conversations by far.


Might I suggest EUAD for the anti-Russia play?
So like StumbleUpon but vendor-locked to already popular services. Any possibility it could get a Fediverse edition? That sounds actually useful instead of supporting continued useage of platforms with boardroom controlled content-selection algorithms.


Right? I went from passively refusing to give Disney my (non-existent) money to actively refusing to give Disney my (still non-existent) money.



I’ve been simmering on some ‘radical left-wing’ grafitti such as;
Be Kind
Build Community
Don’t Hate
Love Thy Neighbor
But I don’t want to get black bagged for spreading such subversive rhetoric.

Seriously, all these comments about fucked-up and predatory content…has anyone considered quitting Facebook? Or just algorithmically-served content altogether? Am I crazy for preferring to build and do my best to expand my own silo rather than having billionaire-owned corporations do it for me?


The cops were probably impressed by his aim and asked for shooting tips.


I’m interested in the long-form articles but have never used RSS, is there a good reference site for learning about it you could recommend?
Bruh they’re just warming up.
A couple street executions here, a detainment and (separate) FBI search of journalists there to gauge public response. They’ll adjust their approach, improve their propaganda and continue dismantling communities.
They’re deep into abducting and concentrating innocent people including children They will continuously escalate their brutal and violent responses to resistance.
They demanded voting records. They aren’t stopping with immigrants and they’re taking the first steps toward cataloging the opposition.
Trump is not in charge. He is the distraction, the orange herring providing cover for the likes of Stephen Miller, Russell Vought and other focused, effective organizations operating in the background. The true consequences of the dozens of executive orders Trump auto-penned in his first months have hardly kicked in yet.
We’re just reaching the second quarter.
