  • It wasn't originally my claim

    Sorry, I wasn't paying attention and missed that. I apologize.

    loads of modern computers don't use DDR5 or ECC variants of older generations at all, so don't have any error-correcting memory. If the wrong bit flips, they just crash.

    Integrated memory ECC isn't the only check, it's an extra redundancy. The point of that paper was to show how often single bit errors occur within one part of a computer system.

    memory errors are really rare

    Right, because of redundancies. It takes 2 simultaneous bit flips in different regions of the memory in order to cause a memory error and it's still ~10% chance annually according to the paper I cited.

  • it's talking about machines with error correcting RAM, which most consumer devices don't have.

    It's a paper from 2009 talking about "commodity servers" with ECC protection. Even back then it was fairly common and relatively cheap to implement though it was more often integrated into the CPU and/or memory controller. Since 2020 with DDR5 it's mandatory to be integrated into the memory as well.

    gives figures around 10% for the chance of an individual device experiencing an unrecoverable error per year, which isn't really that often

    Yes, that's my point. Your claim of "computers have nearly no redundancy" is complete bullshit.

  • I think you are both overestimating the ability of biological systems and underestimating the ability of mechanical systems to be repaired.

    Biological systems have incredible self-repair capabilities, but are otherwise largely unrepairable. To fix issues with biological systems you mostly have to work within the bounds of those self-repair mechanisms which are slow, poorly understood and rather limited.

    Loosing a few skin cells is perfectly normal. Corrupting a few skin cells can cancer cancers or autoimmune disorders. Loosing a few Purkinje cells can lead to significant motor impairment and death.

    Computers, and mechanical systems in general, can have a shit ton of redundancy. You mention ECC, but neglected to mention the layers of error connection, BIST, and redundancy that even the cheap, broken, cost-optimized, planned obsolescence consumer crap that most people are mostly familiar with make heavy use of.

    A single bit flipped by a gamma ray will not cause any sort of issue in any modern computer. I cannot overstate how often this and other memory errors happen. A double bit flip can cause issues in a poorly designed system and, again, are not just caused by cosmic rays. However, it's not usually that hard to have multiple redundancies if that is a concern, such as with high altitude, extreme environment, highly miniaturized, etc. objects. It does increase cost and complexity though so____

    The huge benefit of mechanical systems is they are fully explainable and replaceable. CPU get a bunch of radiation and seems to be acting a bit weird? Replace it! Motor burnt out? Replace it! The new system will be good as new or better.

    You can't do that in a biological system. Even with autografts (using the person's own tissues for "replacements") the risk of scarring, rejection and malignancy remains fairly high and doesn't result in "good as new" outcome, but is somewhere between 'death' and 'minor permanent injury'. Allografts (doner tissues) often need lifelong medications and maintenance to not fail, and even "minor" transplants carry the risk of infection, necrosis and death.

  • Tattoo Ink Moves Through the Body, Killing Immune Cells and Weakening Vaccine Response

    Jump

  • The implications are the variables are conflated and the conclusions are overblown.

    It should come as no surprise that acute trauma and injecting a foreign substance would cause a relatively significant immunological response. The issue is that for the "chronic phase", which is where the novelty of this research lies, the evidence shown is far from difinitive compared to the story being told and what results are shown aren't overly significant.

    Even if you 100% believe the paper the conclusion is that the effect of getting tattooed is, arguably, similar to catching the flu once. However, the paper itself tried to obfuscate that so they have a more impactful result and the marketing/outreach/media site that was linked here doubles down on it trying to sell the story of "tattoos==illness and death"!!!

  • The full paper is here and, as usual, it's hardly anything and decontextualized in order to get a publishable result.

    This one is so bad that it doesn't use established baselines or do any form of statistical analysis on the results instead opting for their own "baseline" measurements using very small sample sizes. It also plays a smoke and mirrors game where it shows a result for short term immunological response and then uses that to insinuate the 'slightly reduced but still likely well within the error of the poor control' long term effects are worth noting.

    Other major flaws:

    • As others have mentioned, mice are a terrible model for this as their skin is very thin and proper tattooing is near impossible.
    • They mention verifying with human cadavers but don't include any data from those.
    • There was no control group, the baseline was an untreated mouse, not one with an acute foot trauma.
    • Mice age very quickly, best I can tell the immunological markers weren't age controlled. 2 months out of a <2 year lifespan is a lot of aging. Again, if there was a proper control to measure against.
    • The obsfucation of the raw data into cheesy and unreadable box and whisker plots is hella suspicious.

    At best it's a very poorly communicated and poorly designed experiment but I suspect that's due to it result hunting.

  • Who wants war with Russia?

    Jump

  • Depends on when you count, but for the Iraq war specifically that's about right for the official foreign coalition forces.

    However, the Iraq war was just one front of the nearly dozen wars that were being fought as part of the "Global War on Terrorism" which NATO perpetrated, the short list of Afghanistan, Iraq, Libya, Pakistan, Somalia, Syria and Yemen, but arguably also including Camaroon, Philippines, Libya, Kashmir, etc.

    Sure, of Europe only UK and Poland were officially deployed to Iraq, but they were actively collaborating with the rest of NATO in a much broader conflict and don't ask about where the mercenaries and security consultants that were used heavily during those conflicts came from.

    It's not a misconception, it's misdirection.

  • Forgiveness can only be granted after an honest apology, acknowledgement of the harm caused, and an honest effort made to undo those harms.

    Her acknowledging the harms that those surrounding her are causing is a step in the right direction, and a step towards forgiveness. But oooh boy does she still have a lot of aplogizing to do and acknowledging the harms that she herself has caused. Not to mention that her current plan isn't to undo those harms but wipe her hands clean of it all.

    Forgiveness is only on the table once she starts championing the causes of the black, hispanic and trans peoples she has victimized.

  • That's because the billions spent on homelessness/poverty doesn't go to those experiencing it but to large non-profits so they can get their reservations at 5* restaurants.

    Seattle specifically is facing multiple lawsuits such as Kicheon V Seattle for violating those "checks and balances". However those violations always seem to be in one direction.

  • Can we have a healthy life only with fruits or fruits and plants combined alone, and if not why?

    Jump

  • There's multiple ways, but as an example in a similar way as nutritional yeast is made by growing a microorganism such as Saccharomyces Cerevisiae and then extracting the products. B12 is made by growing an organism like Propionibacterium Freudenreichii and extracting and seperating those products.

    You then mix the B12 from the Freudenreichii with the inactivated[dead] Cerevisiae.

    Jump

  • Most people here are, correctly, pointing out that going fully vegan easily gets all your required nutrients except for B12. However, this is a mostly solved problem because while "naturally" humans would get it through consumption of animal products it's synthesized via bacteria and it's currently produced at scale via genetically modified strains, such as Propionibacterium Freudenreichii, and used to fortify things like plant based milks and nutritional yeast.

    It is something to be aware of, but it's also not the problem many on this thread are trying to paint it as.
