  • All good mate, I mostly just try and stop the spread of misinformation on Aus gun laws. Most people don’t know much about them.

    The leaver actions are fast. The main difference is that you can leave your finger on the trigger for a pump and are meant to take it off for the leaver action, though you could do it with your non trigger hand. People are also buying left handed bolt action shotguns to get around this, though it’s more awkward. All our shotguns have a capacity limit, usually 5 or less. It looks like these guys modified their barrel mags to hold more.

    You’re not wrong about wasted ammo, reliability and reload speed, but you have to think about the worst case scenarios. Situation: close range, large dense crowd, shooter with an unreasonable amount of ammunition, and best luck in the world with no jams or reliability issues. That’s the formula for mass casualties. This is what our laws are effective at protecting against, primarily by limiting the rate of fire.



  • Yeah no shit mate. That’s why pump shotguns are also under a cat C licence here. The legislators weren’t stupid, they basically categorised things on fire rate and public danger.

    The Adler lever actions are very questionable in my opinion. They are almost as fast. Though the one I tried would jam all the time. Lever actions like that weren’t a common thing in the 90’s so it slipped by for a while.

    And saying that a bolt action is potentially worse than a semi auto is some full on American bulshit. Sure things can jam and go wrong, but in the worst case situation with aresholes like this firing into a dense crowd where aim doesn’t really matter, faster shooting is more casualties.

    I can’t stand these popular science articles that just cherry pick phrases from a paper. tl;dr it’s a very promising result but more observation of other galaxies or other mass consistent observations is needed before we should believe this.

    However, the signal from the MW halo alone does not constitute the definitive proof of dark matter annihilation. Detection of annihilation signals from other objects or regions with consistent WIMP parameters will be crucial for the final confirmation. Gamma-ray observations of dwarf galaxies in the MW halo are fascinating from this perspective.

    I would say the most exciting part is this gives us a mass range to optimise the search with earth based detectors. Start looking for 0.5-0.8 TeV masses.





  • It is about safety limits in the sense that we should not be changing them to solve a PR issue. The accepted principle is ALARA. Governments do allow radiation generating devices and infrastructure usually in that framework. The PR issue is not a result of this safety framework, really it’s more of an education problem. Most people will never understand radiation or statistics well enough to have a good grasp on this. But I think it is getting better. Most people I talk to take issue with the cost of nuclear more than the radiation, especially here in Aus where we have no existing industry. My understanding is even the French are struggling to keep it economically viable, especially when it’s dry.

    Energy density should have little to do with cost. We have a lot of empty space, and we really don’t need to capture all that much sunlight even with 20% efficiency. 20% is just fine when photons from the sun are free. The true cost savings with solar is not in the panel cost, it’s that a dozen people with a TAFE degree can build a 500 MW generator in a paddock in 3 months, that operates with minimal maintenance. Nothing can beat this.

    Economically viable superconducting links are indeed a long way off but I would bet we see them before commercial fusion. In fact, we already have, they exist in a number of grids, mostly as tests and demonstrations. In east coast Aus, we lose close to 50% of our generated power to transmission lines. You take away transmission loss, and you can build a global grid. Aus can power the EU and NA in their nights with solar. It’s never cloudy everywhere at the same time.



  • I mean what’s the hypothetical other option here? We increase the background rate in a city of 10 million people to say, 200 mSv/year for five decades and do the experiment to see if their genetics can handel it to get statically meaningful data? For all we know right now it could be fine, or thousands of people get cancer that otherwise would not have, no one has the data to know. It’s a pretty unethical study.

    Even if you removed all safety requirements from the nuclear industry (never going to happen) it will still be expensive, there is too much infrastructure, too many systems, control loops and moving parts. The reality is solar just wins in cost and it is probably only going to keep making headway over the rest of the generation tech out there. Given the development rate of batteries I expect solar/batteries will become the power generation standard simply though economic drivers more than anything else. I doubt it’s possible to beat that gravity contained fusion, and if we ever get cheaper superconducting links, then it’s basically game over for everything else.

    But we will always have reactors. We need the medical isotopes, and let’s be real, they will keep breeder reactors for bomb fuel.







  • It’s a skill that takes practice and experience more than any golden tidbit of knowledge. Food is wide and varied, what works for one thing won’t work for all.

    There are lots of general pointers, use more oil or, make sure the pan is hot first etc etc.

    One of the biggest misconceptions that people have from Teflon is food sticking and releasing and worrying about that. With Teflon, at least when it’s good and new, nothing ever sticks, at any point, ever. This is not true of anything else. Your steak will stick, for a while, and then it will let go once the protein has cooked a bit. Your pancakes will need to cook for a while before you can get them to release from the pan etc.

    Part of the skill is the implements you use and learning to release various foods from the surface. I like a wooden spatula for bulky things, but I also have a thin polyamide spatula for trickery stuff. The sharp edge on that helps a lot without damaging the pan. You can also use temperature changes to get food to release.

    Lastly, sometimes some food sticks. Don’t sweat it. It’s still edible, don’t let it ruin your meal and learn as you go.
