  • Slow? Not necessarily.

    The main issue with that much memory is the data routing and the physical locality of the memory. Assuming you (somehow) could shrink down the distance from the cache to the registers and could have a wide enough data line/request lines you can have data from such a cache in ~4 cycles (assuming L1 and a hit).

    What slows down memory for L2 is the wider address space and slower residence checks. L3 gets a bit slower because of even wider address spaces but also it has to deal with concurrency issues since it’s shared among cores. It also ends up being slower because it physically has to be further away from the cores due to it’s size.

    If you ever look at a CPU die, you’ll see that L1 caches are generally tiny and embedded right into the center of the processor. L2 tends to be bolted onto the sides of the physical cores. And L3 tends to be the largest amount of silicon real estate on a CPU package. This is all what contributes to the increasing fetch performance for each layer along with the fact that you have to check the closest layers first (An L3 hit, for example, means that the CPU checked L1 and L2 and failed at both which takes time. So L3 access will always be at least the L1 + L2 times).


  • You’re probably affected by this even if you didn’t participate.

    The thing about genetics is you can make reasonable predictions about individuals if you have data on their relatives. Heck, you can reasonably make regional predictions with genetic data that will be fairly accurate.

    If any of your parents, grandparents, aunts, uncles, cousins, siblings, etc took this test, then you are now at least a little exposed.


  • I literally had an econ professor years ago who directly told us “do not take a genetics test”. This was before the ACA

    The reason was simple. It’s information that once a private company gets a hold of it, they will use it to hurt you. Whether it’s a drug company that learns you’re predisposed to addiction, so better to give you it people around you nice temporary discounts on addictive meds, or an insurance company that learns you’re predisposed to cancer, so better to look for ways to deny or drop coverage.

    Once these companies know a little bit about your nature, they’ll exploit any aspect possible to increase profits.

    This was not a progressive/socialist econ professor. Just someone who knows how capitalism works.





  • I’m a different person. It appeared to me that you were lumping in all German citizens with Nazis which is why I made the post.

    I’m not defending Nazi supporters, even in the earliest stages. They j knowingly joined with the antisemites to try and push their own agendas. History tells us how that worked out.

    Jews were citizens of Nazi Germany.

    Now, you might be able to make the case that early Nazi party members, before the rise of power, weren’t 100% antisemitic, they absolutely knew they were getting into bed with antisemites.

    After the rise in power started, Jewish sympathisers were purged from the party. Anyone in or supporting Nazis (which was a large portion of the population) knew what they were supporting.

    I’d just caution painting too broadly. That wasn’t all German citizens that supported the Nazi movement. It was also a brutal regime that stomped out detractors. German media of the era was highly controlled. It’d paint a false picture of the amount of support. True dissent was a dangerous position to publicly take.


  • Yup. What are they actually advocating for? What are their true core beliefs?

    It should also be noted that there are groups you can control your membership of (political parties, religions) and groups you are forced into (ethnicity, sexuality). The group you choose to join speaks far more about how terrible or good you are. The worst groups and people are those that attack people based on groups they are forced into, bigots and fascists.







  • There are simply fine lines. One problem I’ve seen is ND once diagnosed using their ND diagnosis as a crutch rather than a tool to understand and work with themselves.

    Certainly there’s a level of “This person is ND and will never behave in a NT way” that society needs to accept and get over. But on the flip side, there are certainly ND people that will use it as an excuse to be an asshole rather than looking for tools to minimize the impact both on them and others.

    I wear and need glasses. I’d be an asshole if I drove without them even though I have a medical condition that makes it hard for me to see without glasses. A ND diagnosis doesn’t mean that no rules need apply, it means that a struggle in life will be figuring out the best way to work around them.

    Yup. The baker isn’t the one that owns the bakery. They don’t own the mills. They don’t own the farms.

    Instead, what’s happened is one mega corporation has bought most of the bakeries, they set prices to the maximum level possible and have backroom negotiations with mills that an independent baker can’t get in the room to make. The mills do the same thing with the farms. And the farms are all consolidating into few owners who get to run on almost no employees (It doesn’t take a lot to run a modern farm). Further, the mega farms and mills end up driving small time farmers out of business because the mills won’t cut deals with small time farmers like they will with the megafarmers.

    At every layer, there is some MBA asshole idiot justifying his parasitic existence because he thinks nobody else is as smart as him (even though he likely got the business because of his daddy or his wife’s daddy). He hordes the excess funds but builds himself a nice big house.
