    It’s a heater to make hot water. As opposed to a space heater, which is a heater used to heat a space and a food heater that is a heater used to heat food to serving temps and a floor heater which is a heater to warm up a floor.















  • A super computer isn’t just a single computer, it’s a lot of them networked together to greatly expand the calculation scaling. If you can imagine a huge data center, with thousands of racks of hardware, CPUs, GPUs and RAM chips all dedicated to the tasks of managing network traffic for major websites, its very similar to that but instead of being built to handle all the ins and outs and complexities of managing network traffic, it’s purely dedicated to doing as many calculations for a specific task, such as protein folding as someone else mentioned, or something like Pixar’s Render Farm, which is hundreds of GPUs all networked together dedicated solely to the task of rendering frames.

    With how big and complex any given 3d scenes are in any given Pixar film one single GPU might take 10 hours to calculate the light bounces in a scene to render a single frame, assuming a 90 minute run time, that ~130,000 frames, which is potentially 1,300,000 hours (or about 150 years) to complete just 1 full movie render on a single GPU. If you have 2 GPUs working on rendering frames, you’ve now cut that time down to 650,000 hours. Throw 100 GPUs at the render, we’ve cut time to 13,000 hours, or about a year and a half. Pixar is pretty quiet about their numbers but at least according to the Science of Pixar traveling exhibit during the time of Monster University in 2013, their render farm had about 2000 machines with 24,000 processing cores, and it took 2 years worth of rendering time to render that movie out, and I can only imagine how much bigger their render farm has gotten since then.

    You’re not building a super computer to be able to play Crysis, you’re building a super computer to do lots and lots and lots of math that might take centuries of calculation to do on a single 16 core machine.



  • The standards of today are still significantly better than even a hundred years ago. I mean think back to the time of windmills and watermills, to drive massive grindstones. It used to be grinding wheat carried very substantial risks that the flour would have strait up chunks of grindstone that broke off from the milling. London would have regular cholera outbreaks because they were dumping human waste into the Thames where their drinking supply was pulled from. Once they stopped doing that, cholera was dramatically reduced

    At a certain point there are just acceptable risks to the regulations we have to the manufacturing processe we have and we as induviduals just need to be moderately careful with preparing our foods. Washing fresh fruits and veg is always a good idea, cook your food to proper temperatures to kill off enough bacteria, wash your hands when you prepare food, don’t prep raw meats on the same surfaces as fresh veg. If you get salmonella because you cut up raw veggies for a veggie board on a cutting board that you prepped raw chicken on no amount of regulation is going to protect people, and that’s with salmonella already quite rare in a lot of manufactured product, something like 1 in 20 or 1 in 25 at your average grocery store.


  • Unsafe? No, it was well below any regulations for unsafe dosages. However it was detectable above the average baseline which is valid cause for concern because more contamination could happen. It ended up that there was a steel scrap smelter near the shrimp packing facility that somehow got medical equipment that uses cesium-137 got into the scrap and as it was smelted down, a detectable amount of cesium got released into the air and ended up on the shrimp.

    No real world politics crammed into it

    My guy the original trilogy was about the Vietnam War that was literally happening in the 1970s when New Hope was released, the prequel trilogy was about the neoliberal stagnation and subsequent war on terror in the late 90s and early 2000s, the sequel trilogy is the one devoid of cultural relevance to any ongoing events and it suffered because it wasn’t relevant to anyone.
