  • Octopodes have a different nervous system than vertebrates. We have a brain that does almost all of the “thinking” while the rest of the nervous system is either sending or receiving signals (with some “thinking” done below the brain like in the spine).

    Octopuses have a brain, but much of the “thinking” is done by nerve clusters in each tenticle.

    While grasping on object for humans requires signals going from hand to brain and back, for octopi, a lot of the signals can literally just stay in the tentacle.

    It makes sense in that context that they would learn tasks in specific tentacles.


  • I think the main thing that’s happening is analogous to what’s happened with a lot of electronics over the past couple of decades. It seems like every electronic device runs off of a way more powerful computer than is necessary because it’s easier/cheaper to buy a million little computers and do a little programming than it is to have someone design a bespoke circuit, even if the bespoke circuits would be more resource efficient, robust, and repairable. Our dishwashers don’t need wifi, but if you are running them off a single board computer with wifi built in, why wouldn’t you figure out a way to advertise it?

    Similarly, you have all sorts of tasks that can be done with way more computational efficiency (and trust and tweakability) if you have the know-how to set something bespoke up, but it’s easier to throw everything at an overpowered black box and call it a day.

    The difference is that manufacturing costs for tiny computers can come down to be cheaper in price relative to a bespoke circuit, but anything that decreases the cost of computing will apply equally to an LLM and a less complex model. I just hope industry/government pushing isn’t enough to overcome what the “free market” should do. After all, car centric design (suburbia, etc) is way less efficient than train centric, but we still went there.

    My work would be improved by the dumbest of dumb retrieval augmented models: a monkey with a thesaurus, ctrl+f, and a pile of my documents. Unfortunately, the best they can offer is a service where I send my personal documents into the ether and a new wetland is dried in my honor (or insert your ecological disaster metaphor of choice).



  • The real reason behind all the gelatin salad abominations is that after gelatin was first discovered/isolated, it was very costly to produce, but new technology made it much more affordable.

    Isolating gelatin requires long cook times (which require lots of fuel) at ideally fairly low temperatures. Then there needs to be some level of filtration to make it as flavorless as possible, and then dehydration to sheets or a powder.

    Finally, to actually make one of these “salads”, you need refrigeration.

    Production of gelatin was industrialized to make it much cheaper, and refrigerators became normal household appliances. You went from gelatin being only really used in “fine dining” to something you could do at home. In the same era, pineapple went from being a fruit that only the rich could get to something anyone could, so it went through a similar explosion of popularity.

    The alternative funny answer is that the company that sold gelatin, Knox, was run by a husband and wife, and all the crazy stuff didn’t start until the husband died, so either he was holding her back, or once she lost her husband, she thought everyone else should, too.




  • I’ve made wine (and a lot of beer). It’s not hard, and people have been doing it for ages, but creating a good, consistent product does rely on chemistry/biology knowledge that they wouldn’t have had back then.

    I suspect that a lot of the mystique around wine (like the idea that terroir is magic) is just down to the fact that a few hundred years ago, most wine/beer was trash, and the only stuff we’d consider “good” by modern standards is just down to luck that a batch didn’t get infected with the wrong yeast/bacteria, or exposed to too much oxygen, or a style that is meant to be drunk young (vinho verde) or oxidized (sherry).

    There’s probably good reason that much of the wine that was aged/transported long distance a couple hundred years ago was fortified (Madeira, Port, sherry, vermouth, etc.).

    Millenia of selective breeding have changed grapes, too. Without knowing for certain, my guess would be that on average, the sugar concentration in the raw grape juice would be roughly the same as now, but relying on wild yeasts or polycultures would not ferment as completely, so the final product would have lower ABV and higher sugar.

    In beer, the actual grain and malting technology has greatly changed over time. 150 years ago, German immigrants to America couldn’t brew the lighter styles they were used to because American grain was much higher in protein so they had to dilute it with corn/rice. Older grain had a higher propensity for certain defects, too. Basically you had more inconsistency back in the day, and also just some things that were different.


  • People usually don’t log stuff that they see every day. So a person who lives in Oregon (statistically more likely to be in doug-fir country) goes east and notices that a different tree predominates and they want to know what it is, they’ll log it.

    Personally, I log stuff that I don’t normally see cause there’s a chance that it’s either: a rare native plant, a native plant on the edge of its range, or a non-native. Those are all things that I’m less likely to know off the top of my head, and I think it’s probably more important to tag for scientific purposes.




  • Total War: Empire. I’ve previously played Rome 1/2, Medieval 1/2, and Atilla. For anyone who’s played other total war games, there are a couple of game mechanics that are new in Empire.

    There are actual naval battles, where you put ships into a battle line, and you can board enemy ships. It’s cool but hard (for me) to control. Also many of the buildings in a territory aren’t located in the capital because it’s meant to represent colonial holdings, so you can have a sugar plantation or something outside the protection of a city, and a lot of the warfare ends up being small skirmishes sacking outlying buildings.



  • My front loading clothes washer. It frequently doesn’t drain right. If you create a fault tree on what causes that, you can have:

    • Faulty water level sensor
    • Clogged water level sensor hose
    • Clogged filter
    • Clog around the heating element
    • Broken check valve
    • Faulty pump
    • Clog between drum and liner
    • Faulty control board

    The pump can clearly be heard running when the water levels are too high, so I know the sensor, sensor hose, controls, check valve, and pump are all functioning. Sometimes, the pump runs for way longer than you’d think necessary, with only a small trickle of water coming out little bit by bit. This indicates to me that there is a clog upstream from the pump. Multiple times, I have squeezed myself back behind the washer to take the back off and access the filter (which should be accessible from the front). I’ve found no clog there. Ive taken out the heating element to check for clogs around it, and found nothing there. Ive shown a bright light from inside the drum to highlight any potential clogs between it and the drum, and seen nothing there. Despite all of that, the problem remains, and when I manually spin the drum with nothing inside, I can hear what sounds like stuff moving around inside.

    I assume it must be ghosts or something at this point.




  • One thing to keep in mind with a lot of responses is often when someone says “we didn’t learn about x in high school”, what they should be saying is “I didn’t learn about x in high school”. I’ve certainly heard former classmates claiming not to have learned something even though they were sitting next to me when I learned it.

    When i was a preteen, we learned about WW2, mainly from a US perspective, and had a fairly large focus on the holocaust, including a visit to a holocaust museum.

    As a teen, I had a class on specifically European history. In there, we learned about lot more about the rise of the nazis (though not much on Italian fascists).

    Here’s the tl;dr on what I remember learning about then:

    WWI ended with the treaty of Versailles which was not a realistic, sustainable peace. We learned about the economic trouble like hyperinflation. We learned about the beer hall putsch, and that it was effectively unpunished. We learned that Hitler then sought power through legal means by allying with a broad range of groups unhappy with the current government. As he rose to power, various elements were purged from the government. Concurrently, political violence from the stormtroopers suppressed minorities and other enemies from organizing against them. This culminated in Hitler being elected chancellor, and then the enabling act gave him ultimate power. In the night of the long knives, all the allied elements in the party were purged. After that was kristallnacht, the remilitarization of the rhineland, annexation of Austria and the sudetenland, and then finally the invasion of Poland.


  • Yeah, I think this is the most reasonable approach. Everyone else is suggesting that falling on your sword is the first line of defense, and it really shouldn’t be.

    If you are the attorney general, and the president asks you to fire someone prosecuting him, sure, resign.

    If you are just some person trying to get by, shooting yourself in the foot isn’t going to help anyone. If you refuse to do a job, and they just hire someone else to do it, you’ve only really lost a lot at the cost of a small moral victory immediately rendered nil.

    Not to get too utilitarian, but the ultimate goal should be to have the best outcome for everyone, not to just make the first decision that seems to be right.

    There’s a saying about fascism “Do not obey in advance”, and the idea is that during the rise of fascism, the fascists don’t actually have to make people do what they want. Lots of people comply with their goals well before being forced to. We are seeing many companies eliminating DEI objectives because it’s what the fascists want, even though they don’t have to.

    This could be one of those situations where a frank conversation with the project lead to see if that’s what’s happening because there is a chance to convince them not to obey in advance. It could also be that the training is going for federal agencies that have been “legally” required to eliminate “gender” from any training materials.

    I think it would be foolish to turn down the job without at least establishing that.



  • For a disease to be prevented from spreading, you need a certain percentage of people to be immune. It’s different from disease to disease and also depends on the vaccine itself. Some diseases like Covid can still be spread to people who are vaccinated (though obviously the worst of the symptoms are mitigated).

    For the sake of example, let’s say you need 90% immunity for a disease to not spread. Maybe 5% of the population cannot be vaccinated due to immune conditions, being too young, etc. That gives 5% of wiggle room.

    Then there are acolytes of the fraudster, Andrew Wakefield, who faked data to get a flashy headline to get published in a prestigious journal. That includes RFK jr., Jenny Mccarthy, mayim bialik, etc. Clinging to their views for so long makes them unable to change them even if you show them proof that they are wrong. That might be another 1% of people.

    There are a very small percentage of people who shun vaccines for lets say “true” religious reasons. Most of the people who try to claim religious reasoning for refusing vaccines are members of religions that are completely fine with vaccines. They are usually just really stupid people who are scared of needles and/or don’t think it’s that big of a deal with modern medicine. That’s probably another 1% of people.

    Then there are people that are homeless or otherwise outside of the system. Vaccines are one of the most cost effective methods to improve health of a country, so despite the nightmare that is our healthcare system, you typically should never have to pay for a vaccine. It may be a bit more work than someone who is homeless and/or has substance abuse or mental health problems can prioritize. That might be another 1%.

    All together, that would put us at 92%, above the threshold for a widespread epidemic, but all of those categories of people who don’t get vaccinated tend to be in communities, and so we can have outbreaks in those communities.
