  • There's a lot of answers here, but I don't think anyone said the magic words. To reseason cast iron, you need an oil high in poly-unsaturated fatty acids. Those are the kind that can chain together, and form a good polymer coating.

    The thing that trips me up most about this subject is that 140 years ago, pork fat was very good for seasoning cast iron. Today, it isn't, because the composition of the fat has changed significantly.

    The best seasoning coats will be thin, not appear or feel oily, give the pan a dark color slightly more glossy than an eggshell, and resist mild detergents, metal spatulas, and heat high enough to sear a steak on. If you have a layer of loose stuff in the pan, that's just a layer of gunk, and is probably adding some weird flavors to anything you cook.

  • The (really, really, really) big problem with the internet is that so much of it is garbage data. The number of false and misleading claims spread endlessly on the internet is huge. To rule those beliefs out of the data set, you need something that can grasp the nuances of published, peer-reviewed data that is deliberately misleading propaganda, and fringe conspiracy nuts that believe the Earth is controlled by lizards with planes, and only a spritz bottle full of vinegar can defeat them, and everything in between.

    There is no person, book, journal, website, newspaper, university, or government that has reliably produced good, consistent help on questions of science, religion, popular lies, unpopular truths, programming, human behavior, economic models, and many, many other things that continuously have an influence on our understanding of the world.

    We can't build an LLM that won't consistently be wrong until we can stop being consistently wrong.

  • I talked to one of the authors of the New American Bible, who told me the text is a mistranslation, and it's more like "harder than putting a rope through the eye of a needle", which would've been an idiom familiar to the fishers in the area.

    It means "impossible", which is suitable because the things Jesus called for you to do make a rich person into a not rich person, as far as material wealth goes.

  • "Along with Mitsubishi HC Capital, more than 20 other lenders have filed claims totaling $637 against Pride Group, according to filings with the U.S. Bankruptcy Court for the District of Delaware."

    I know it's a nitpick, but I don't like when articles just leave out the million in a sentence like this. C'mon, editor... numbers are important.

  • The problem when photon containment breaks like this is that we can never be 100% sure which photons were SUPPOSED to be there, and which ones leaked out. We'll need a dedicated team of particle physicists with very small tweazers to have any hope of sorting out this mess.

  • I managed a CentOS system where someone accidentally deleted everything from /usr, so no lib64, and no bin. I didn't have a way to get proper files at the time, so I hooked the drive up to my Arch system, made sure glibc matched, and copied yum and other tools from Arch.

    Booted the system, reinstalled a whole lot of yum packages, and... the thing still worked.

    That's almost equivalent to a reinstall, though. As a broke college student, I had a laptop with a loose drive, that would fall out very easily. I set it up to load a few crucial things into a ramdisk at boot, so that I could browse the web and take notes even if the drive was disconnected, and it would still load images and things. I could pull the cover off and push the drive back in place to save files, but doing that every time I had class got really tiring, so I wanted it to run a little like a live system.

  • I tried typing this once before, but kept running into situations were I'm not sure if I'm just being condescending. These are the most obvious reasons this is a selfish and self destructive perspective:

    When you are old, children today will be the only people able to take care of you. Optimizing society so that there are many more old people than young people will create unfair burden on the next generation, and probably lead to horrific suffering for millions of people (probably including you).

    Children are best raised by stable, happy, healthy families, and they are more productive members of society (and happier) when that happens. Because we want the next generation to be happy and productive, aiding today's parents helps us all tomorrow. Adding financial strain causes many negative effects for families, and therefor for children, and therefor for society at large.

    Unless you are extremely lucky, you probably faced issues in your own childhood that would have been lessened if your parents had more money. Wishing the same, but worse on the next generation is twisted.

  • I'd rather focus on ripping cars out of cities, promoting mixed use zoning areas, removing regulations on food service (which is the reason small American food vendors need food trucks, instead of "street food" like the rest of the world.

    The disjointed, car based, child hating society we have is a big problem.

  • What we have done is invented massive, automatic, no holds barred pattern recognition machines. LLMs use detected patterns in text to respond to questions. Image recognition is pattern recognition, with some of those patterns named things (like "cat", or "book"). Image generation is a little different, but basically just flips the image recognition on its head, and edits images to look more like the patterns that it was taught to recognize.

    This can all do some cool stuff. There are some very helpful outcomes. It's also (automatically, ruthlessly, and unknowingly) internalizing biases, preferences, attitudes and behaviors from the billion plus humans on the internet, and perpetuating them in all sorts of ways, some of which we don't even know to look for.

    This makes its potential applications in medicine rather terrifying. Do thousands of doctors all think women are lying about their symptoms? Well, now your AI does too. Do thousands of doctors suggest more expensive treatments for some groups, and less expensive for others? AI can find that pattern.

    This is also true in law (I know there's supposed to be no systemic bias in our court systems, but AI can find those patterns, too), engineering (any guesses how human engineers change their safety practices based on the area a bridge or dam will be installed in? AI will find out for us), etc, etc.

    The thing that makes AI bad for some use cases is that it never knows which patterns it is supposed to find, and which ones it isn't supposed to find. Until we have better tools to tell it not to notice some of these things, and to scrub away a lot of the randomness that's left behind inside popular models, there's severe constraints on what it should be doing.

  • That estimate is based on assuming that the ratio of matter to light output is the same between galaxies 10 billion years apart in age. The high light output of these young galaxies could also be supermassive stars that burn out very quickly, larger stars typically forming faster than smaller stars, or many other things.

    Blindly assuming a linear relationship between two things, then extrapolating is how you get the Windows loading bar circa 2000.

    Separately, but just as big a potential issue, the data itself may be incorrect. Previous galaxies measured at extreme redshift values were remeasured, and found to have less extreme values. This can be as simple as there aren't that many photons from these galaxies reaching us, so a short measurement period might not be enough to get an accurate picture.

  • As the President and CEO of a fortune 500, and a neurosurgeon that does rocket surgery as a side project, there are many people relying on me to be an upstanding member of the community at all times.

    In reality, most of the ways I misrepresent myself are to obscure my identity, and mostly it's by leaving things out.

  • In my mind, the line is that an engineer is someone that can commit a crime by doing their job incompetently. If the only things at risk are your job and your pride, that's a different thing.

    "I program all day, so there's a lot of trial and error. My friend is a negligent civil engineer, so there's a lot of error and trial."

  • I'm a Senior Computer Software Developer Programming Engineer, or SCSDPE (which is pronounced Skuzz-Deep), and I will be irreparably miffed if you get it wrong.

    For your convenience, I also accept "that guy that sits weirdly close to the water fountain", "hey", and "paid keyboard user".
