  1. Pedagogy research has been done. The results tell how teaching should happen. If you know the research and apply the conclusions, students will succeed.

    I'm inclined to believe this is true, that by now the research has been done and it's fairly well understood how to teach.

    My question is, if this is the case, why does it seem like there's still such a wide variety of teaching? Why so many charter schools, differing "systems", etc? Shouldn't research-based teaching methods actually just eliminate the so-called achievement gap, with the remaining poor learners actually a product of poor parenting/poverty?

    I feel like how to teach ought to be a fairly solved problem, and that the methods best backed by research should be fairly well taught in teacher education programs. But it seems like on the ground, there's constant churn of new trends/methods/philosophies. It's like if research identified how to cure a disease, but instead of standardizing on that therapy, people kept insisting that it didn't work and that some other newfangled method that contradicted existing research was better.

    I can't say why, but I definitely get the vibe that Reddit has a lot of low income people among its user base.

    My best theory is that it skews very young, and it demonstrates that the dominant age demographic is just showing how bad wages are. I'm not convinced, though, as in my experience the internet has always skewed young but so many postings I see on Reddit kind of scream "poor and more rural".

    But it could be some other, weirder dynamic involving Reddit's appeal among less affluent people generally. I kind of wonder if more affluent people are more drawn to Facebook and Instagram because photo sharing is easier and those platforms allow for more wealth flaunting. Reddit is a less convenient platform for that kind of thing.

    I just don't see how this could be the case -- I smoked for a decade and *liked it*. In the years since I quit I have tried a few cigarettes out of nostalgia and been absolutely repulsed by them. When I smoked I rolled my own, and occasionally a "light" cigarette smoker would want to try one out of curiosity or because they were out, and almost universally they hated them.

Unfortunately, though, you have to design for the 20% of the population for whom excessive consumption is the only consumption they know.

    I'm not sure the "psychologically addictive" part can be really solved due to the fuzzy nature of psychological addiction and how even non-drug activities can more or less also be called psychologically addictive. But maybe if one of your successful engineering goals was a drug that wouldn't provide an effect if taken more than, say, 4 times a day, perhaps even psychological habituation wouldn't be that negative since you'd have a hard limit on how much reward could be provided.

    I keep thinking there must be a way to engineer a close-to-optimal recreational drug and wonder why it hasn't happened.

    As for design criteria:

    * Diminishing returns on adding additional doses. Either because the drug itself can't bind to receptors beyond some optimal dose, or because its some kind of binary drug with its own antagonist which isn't potent enough until you take the 3rd or 4th tablet. IIRC, some sublingual buprenorphine formulations include nalaxone, which makes them useless for injection but the nalaxone has weak oral bio-availability, so when taken orally it doesn't take effect.

    * Relatively short half-life, losing effectiveness after about 4 hours. This might help with ancillary problems where a user has poor motor reflexes or where long-term side effects contribute to some of the problems of "drug use". If you could get pretty high and then it went away relatively quickly, it'd be better than getting moderately high but having the effect last 8 hours, at least from a behavior/lifestyle/side-effects basis.

    * No synergistic effects with common other drugs. Try to avoid the problem of taking $engineered_drug and alcohol or other drugs and making a worse or dangerous effect.

    It seems like if we had a *better* drug that was legal we'd solve a lot of problems and perhaps keep a lot of people from bothering with more dangerous, expensive black market drugs.

    Cannabis seems to pretty close to this, but not quite perfect.

    So if black tar is highly viscous, basically tar-like, how the hell are they adding fentanyl to it? Is it happening at the "source" where they're cooking down opium to morphine base and then converting to heroin? It sounds extremely non-practical to try to add fentanyl to tar just from a materials properties basis.

    I've read that a lot of counterfeit pills are out there with fentanyl, and honestly, it's kind of what I would expect would happen with fentanyl. Mostly because it represents what I assume someone more forward thinking in the drug business would do -- come up with a generally reliably non-toxic method of blending fentanyl with a bulking agent to sane doses and then sell pills.

    It's kind of crazy, but I would expect whatever cartel/network who could sort out how to make pills at "reasonable" strength (similar to Oxy 30s or 60s) would end up with a decent business. I mean your customers aren't dying immediately and you have a product with broad appeal -- clean, non-scary pills for white collar types, and something with a lot of oomph for those who want to mainline, all in a simple and easy to carry form factor that slips into a bottle of over the counter medicine for no-fuss, no-muss storage and transportation.

    A century ago, most of these drugs (i.e. cocaine, opium, etc.) were available to the general populace

    Most of the available opiates were a lot weaker and diluted into oral tinctures that cuts their bio-availability. Most users weren't injecting them, and in fact smoking opium was the predominate form of "opiate abuse" into the 1920s.

    Succesive bans and increased enforcement pushed illicit varieties into their more concentrated forms to aid in evading enforcement. This is more or less what happened once the DEA cracked down on overprescribing oral narcotics. People switched from pharmaceutical grade and lower dose pills to street heroin, and when supply couldn't match demand, synthetics like fentanyl got into the mix, partially abetted by the ease of obtaining them from corrupt Chinese labs.

    I figure eventually a more or less reliable kitchen sink method is going to be developed for cutting and bulking fentanyl, some kind of solvent dilution combined with a binder which can be dried and handled at gram-size masses, capped into pills, etc.

    This will create real problems because what has really held heroin back has been its complex supply chain, from poppy field to consumer. If you can cut this supply chain to a single lab that can synthesize fenatnyl it creates a ton of problems for enforcement. One, you can't just trace shit from "farm to table" so easily, and fentanyl is so potent that in its raw form it greatly reduces smuggling risks.

    Why bother with blending with heroin at all? Why not just cut fentanyl to super-strength heroin potency and sell it as your super strength heroin?

    It makes logical sense -- fucking fentanyl is hard to cut to a dose that won't kill an entire division of infantry at once, I can't imagine getting a partial dose useful for boosting weak heroin is easier.

    If the "drug lords" could ever get just enough chemistry to *reliably* cut fentanyl to heroin strength, its going to make the opiate problem that much worse. AFAIK, fentanyl is made via total synthesis, while heroin is still derived from opium, which is somewhat worse from a supply chain perspective. Total synthesis can be done anywhere, and doesn't have tell-tale poppy farms.

There's losses in the process from a chemistry perspective in addition to basic inefficiencies in collection, contamination, etc.

    Besides all of that, I think the political dynamics of population expansion too much beyond where we're at now is a much bigger problem. I think incremental increases in resource scarcity result in exponential growth in resource hoarding, conflict over "unclaimed" resource pools, and general cultural conflict between population centers unwilling to compromise on certain rules of living.

    Does it mean only to internal Google employees? I think this is probably closer to the meaning, but both Apple and Google employ thousands of contractors who are not officially Google employees, but most people would consider a contractor working for Google to be an internal use.

They would issue a new 90 day license key with every month's payment -- stop paying, and the software stopped without any intervention.

Was immediate revocation a term in the contract? Does their cancellation appear to be associated with some other business competition or dispute? Some of these things could result in injunctive relief from a court if they could be shown to be true and worth litigating.
