Destiny reacts to Hasan not being able to name one book he read growing up "I read a decent amount..don't really read as much anymore but I did..um I don't know, I have no like immediate books that come to mind..I'm also terrible at recall in general..if u ask me about any songs, I can never tell u..ask me what my favorite movie, I have a really hard time pulling from my brain..maybe bc it's packed with ridiculous pieces of information about American politics or American history or just world history in general..I'm also very jetlagged rn" -H "Oh no..here's what I don't get..he has a communications or poli sci degree..couldn't u just name a book that u read in class..that's just crazy" -D

Platner wrote a ton about his political beliefs on Reddit. He didn’t think it’d be read. He was a woke BLM guy who talked about the struggles of LGBT marines & got into arguments with Holocaust revisionists. There is no Nazi on earth who would talk like this. It’s dispositive.

"Vote blue (or red) no matter who" is a bad heuristic; it's good to have some standards, otherwise you tend to be the sucker in the bet over the long run.

we are about to see unprecedented amounts of mental illness and sephiroth-posting from the centrist libs on here

You do get it, right? Once the bar is lowered to “abusive lying dirtbag with Nazi tattoo is okay,” things deteriorate. The next guy (because of course it’ll be a guy) won’t have baggage, he’ll have a U-Haul, and standing in his way will be that much harder. And so forth.

Democrats have spent the last ten+ years bemoaning the evilness of Republicans who acknowledge Trump's flaws, but support him anyway because "the alternative [ie, the other side being in power] is worse." Then along comes misogynistic racist Nazi tattoo guy, and every single Democratic politician is obligated by the base to support him because... drumroll.... "the alternative [ie, the other side being in power] is worse."


the guilt of being the son who loves his family but breathes easier when he's far away

That is the revelation of the Platner campaign. There is literally nothing that is so bad that it can derail his campaign if he is a Democrat Nazi tattoo? sure, why not Domestic abuse? hey, everyone does it Sexting underage girls behind your wife's back? we put out a video of the wife saying that was all cool, how dare you be upset about it

Ok, fellas, we see all your tags and we get it. But. Being a shitty person doesn't make someone a legitimate military target under international law. Climbing on a tank for internet clout isn't enough to become a combatant. Do something that actually qualifies — then we can talk. Until then, we'll keep our drones for real military targets 😉




I've seen a lot of people saying that AI datacentres in space will not work due to the thermal energy from the GPUs. So, I went and actually did some calculations to see how easy it would be to cool down these satellites. (Spoiler: these satellites will work) CALCULATIONS: So, starting with the Stefan-Boltzmann law: Q = ε×σ×A×(Tₛ⁴×Tₑ⁴) A in this equation is the area required to radiate all the thermal energy. Rearranged to solve for area including extra energy radiated from the Sun and Earth: A = Q×Qₑ/ε×σ(Tₛ⁴×Tₑ⁴) Q = watts of thermal energy. SpaceX is aiming for 150KW of power from the solar panels which I have assumed will be entirely converted into thermal energy. Qₑ = watts of thermal energy from radiation from the Sun and Earth. I guessed a value of around 25KW of extra thermal energy incident on the satellite's body, which is probably a MASSIVE over estimate since the satellite is flat and facing 90 degrees relative to the sun. The solar panels wouldn't transfer much heat either through the tiny metal parts which they are attached to. ε = Emissivity of the surface. Apparently the radiators on the ISS have an emissivity of 0.92 so, assuming no advancement in the technology in the decades since they were made, I went with that value. σ = Stefan-Boltzmann constant 5.67×10⁻⁸W/m²K⁴ Tₛ = Temperature of the radiators I am assuming a temperature of 25°C (298.15K) for the satellites, which is quite cool considering the GPUs will probably be operating at temperatures at or above 70°C. Tₑ = Temperature of the surrounding environment Space is about 2.7K (-270.45°C) Putting all of these numbers into the equation: Area = (150×10³ + 25×10³) / 0.92 * 5.67×10⁻⁸ × (298.15 × 2.7⁴) = 424.55m² Now, 424.55m² sounds like a big radiator but let's find out how big each one will actually have to be. Each radiator is double-sided so we divide the area by two which gets 212.27m². Then, since there are two radiators, divide by two again to get 106.14m². The Starship payload door is about seven meters wide, but let's cut down the width of the radiator panels to 6.5 for a little more margin. 106.14 / 6.5 gets us 16.33 meters long. CONCLUSION: In the renders provided by SpaceX, the radiators seem just a little too small according to my calculations. However, I made sure to chose values according to the worst case scenario in my calculations. Just removing the heat radiated from the Sun and Earth from the equation (which I believe would be negligible due to the position of the satellite) returns a length of 14 meters, which is much closer to my estimated length of 13 meters from SpaceX's renders. Using the actual numbers would probably give a radiator with a size very close to what SpaceX has shown us. So, after actually doing the maths, I believe the designs which SpaceX has shown will work just fine. It turns out the very intelligent people at SpaceX know what they are doing.

You know the reason your Stanley or Hydroflask is so good at keeping your water cold is because there's a vacuum inside the walls of the thermos. Heat can't conduct in a vaccum. And "radiated" heat is ineffective at the temperatures processors operate at. This satellite will be like plugging in your gaming PC without a CPU cooler. It'll be dead in minutes.
