  • This makes one of the "solutions" from the article: "A law was introduced at the end of 2023 that will eliminate the need for permits and environmental impact assessments for bridges that are being widened to add lanes as part of renovations." look particularly shortsighted. Infrastructure is a maintenance debt that we are reckoning with, so we will make it easier to build specifically bigger infrastructure so that in 25 years we will have an even bigger problem to solve? Not to mention the concept of induced demand meaning that those lanes are going to increase the amount of vehicles using the bridge, which would be exactly the kind of thing that should get an environmental assessment, versus repurposing some lanes for sustainable transit or building a separate bridge for those modes

  • If you use the right color of light, then the doppler effect means that the atoms will only absorb (and be pushed by) light that they are headed towards. That means that the light will always act as a brake for the atoms and never an accelerator, so the fluid will cool. If you do this from all directions, the fluid will start to stay still in one place and get very close to absolute zero. Idk, I just read the Wikipedia article, but that is my best attempt at an ELI18

  • Radiation does not by definition make things it impacts radioactive, and most of the lingering effects that we associate with radiation have to do with radioactive particles that are left behind by the atmosphere. Since there is no particulate matter traveling between the sun and Mars (photons not withstanding), the surface of Mars would not be expected to acquire radioactive properties from an acute solar radiation event like this one. However, an entity on the surface of Mars would be exposed to radiation from the Sun, much more so than an entity on/near earth and it's magnetosphere (Mars' thin atmosphere and distance from the sun probably helps reduce that disparity relative to something in say low earth orbit, but I don't think it fully equalizes or shifts the scales). I am not an astrophysicist, so there's at least a 20% chance I got part of that wrong.

  • Pi is an infinite series of non-repeating digits, and yet you will never find the letter A in pi because there is a 0% chance of the letter A being a digit in a decimal system. By the same logic, infinite possibilities do not guarantee that every conceivable state occurs, if that conceivable state has a 0% probability. As finite beings, it is very difficult for us to accurately distinguish between a 0% probability and a infinitesimal probability, so we end up circling back to "we don't know"

  • Buses and trains. That, or spaghetti interchange that are bigger than the rest of the city. Also, replace key arterial roads with a pedestrian path, call that path a park, and charge $20 for entry. That will easily fund all the city services and nobody will be too inconvenienced by having to pocket their car as they walk across the "park" to get between neighborhoods. Now excuse me, I have to go murder a little blue bird that won't shut up about the garbage piling up

  • You're not wrong that GPU and AI silicon design are tightly coupled, but my point was that both of the GPU manufacturers are dedicating hardware to AI/ML in their consumer products. Nvidia has the tensor cores in its GPUs that it justifies to consumers with DLSS and RT but we're clearly designed for AI/ML use cases when they presented them with Turing. AMD has the XDNA AI Engine that it is putting its APUs separate from its RDNA GPUs

  • Fair enough. Was just asking because the choice of company surprised me. AMD is putting "AI Engines in their new CPUs (separate silicon design from their GPUs) and while Nvidia largely only sells GPUs that are less universal, they've had dedicated AI hardware (tensor cores) in their offerings for the past three generations. If anything, Intel is barely keeping up with its competition in this area (for the record, I see vanishingly little value in the focus on AI as a consumer, so this isn't really a ding on Intel in my books, more so making the observation from a market forces perspective)

  • Why call out Intel? Pretty sure AMD and Nvidia are both putting dedicated AI hardware in all of their new and upcoming product lines. From what I understand they are even generally doing it better than Intel. Hell, Qualcomm is advertising their AI performance on their new chips and so is Apple. I don't think there is anyone in the chip world that isn't hopping on the AI train
