> A vast majority of participants endorsed [Quotation note: Had used] cannabis use at waves 1 (88%) and 2 (94%), with a mean age of onset of monthly use of 13.7 years. Further, participants reported using, on average, 8.4 (SD 1⁄4 10.8) days per month in the previous 6 months at wave 1.

They’ve collected a group of urban kids whom the vast majority are using cannabis, many starting years prior to this survey.

I know it is chic to be skeptical, but this is one study where I think it is also correct. The study leads the reader to believe that there is a biochemical link between cognitive performance and cannabis as a substance [0]. On the other hand, the evidence they present is that a small minority of kids aren’t using and are performing better. The number of confounding variables is much, much higher than simply alcohol use (Which in the second wave was at 99%, not much to normalize for) and family situation. For example, drug use can result in being kicked off sports teams, suspensions, things that could hinder intellectual development.

Is anyone convinced by the study and would stand to offer support for its conclusion?

[0] To me, the following quote can be read to support this assertion: “ Moderate adolescent cannabis use may have adverse effects on cognitive functioning, specifically verbal memory, that cannot be explained by familial factors”

The problem with this line of thinking isn't that it's wrong. I could complain about the media all day.

The problem is that main stream establishment media: NYTimes, APNews, The Guardian, Reuters, etc are the best we have.

Litter Robot is faster and simpler, much preferred.
Here is the actual sentence the title was edited from:

This is brilliant. Asphalt mostly consists of polycyclics. Maltenes make up the continuous phase, and are typically alkane-modified resins. Compared to plastics, these are much shorter chains. They are also prone to UV degradation which causes brittlement, leading to road degradation.

Asphalt is just nasty stuff. I'd love to see it get replaced with alkanes (polyethlene and polypropylene from plastic, polyisoprene from rubber)

I have had a mini split system in my basement for 5 years and I am the only one I know who has one. They are around enough that Home Depot carries them and yet rare enough that many HVAC contractors do not have experience with them. It was a great retrofit for my basement office. However, my system is oversized. It is in the 90s F and high humidity outside and when I have the system set to 72, it makes the basement 64 degrees F and I have a space heater on under my desk since my computers don't put off nearly enough heat.

The relative humidity in my basement is 48% which is AMAZING for Georgia. That thing plus the dehumidifier makes it the perfect home office and pantry storage.

My favourite fallacy of all is the fallacy fallacy: whereby it is a fallacy of an argument to reject another argument if it contains or is composed of a fallacy. (https://en.wikipedia.org/wiki/Argument_from_fallacy)

"In answer to a question I posed to Nuscale at the town hall we have learned that the plan to save costs by fabricating the modules at a remote factory and shipping them to the Idaho site has been abandoned. The artful response to my question said that Nuscale engaged with approximately 40 … pressure vessel fabricators worldwide and … determined that Nuscale will use existing factories … in lieu of building its own factory.

The major module subcomponents will be manufactured at multiple manufacturer locations and shipped to a single location for assembly prior to installing into the facility.” This signifies the failure of one of the major cost-saving features of the Nuscale project, which was to forestall this exact scenario."

In France this 'success story' led to a state law (2015-992, from 2015, the "loi relative à la transition énergétique pour la croissance verte") stating that the part of nuke-produced electricity must fall to less than 50% in 2025, from 72% then, and that renewables must replace it.

In France nuke-power is backed by gas (which produced 10,3% of gridpower in 2017).

The sole reactor currently planned (Flamanville-3) is a complete disaster, more than 10 years behind schedule and 4x overbudget.

Cash is one way to judge talent. How much cash would people pay for a service? If you can make money off glass jewelry, you're a decent jeweler. An objectively great chef would have people booking his restaurant months in advance and charge hundreds or thousands of dollars for a meal. If you're not able to make a cent off it, you're not yet skilled enough.

In the classes I teach, I design the skills learned in terms of cash. A 3 day class will teach you enough to avoid paying a professional to do something, but not enough to get a job. A 3 month bootcamp will be enough to land you a nice job, but not $X salary.

> There is not a technical solution to any of this.

I don't quite agree with that. In general, our best means of knowing with reasonable confidence whether some event being reported on is true is our confidence in the person telling us of the event. If it's someone we know personally, that's best. In a world of billions of people, that's not possible for most world events, so we can think of trust as being transitive. I can put more confidence in something that's reported by someone who is personally vouched for by a friend of mine, than something that's three steps removed, and so on.

The trouble is that our human brains are incapable of understanding social networks with more than a hundred or so people (i.e. Dunbar's number) and even those we have very imperfect understanding of. Computers don't have that limitation. Supposing you have a directed graph of every human who is willing to publicly vouch for the credibility of some other human, you can run something like PageRank on that to determine the degree to which you should trust some random reporter.

Better yet would be something like PageRank, but modified to handle anti-endorsements as well. There are ways to handle distrust in PageRank-like systems, but that's a little outside the scope of the point I'm trying to make.

Of course, collecting this directed graph of endorsements is outside the ability of a normal human, but sites like Facebook and LinkedIn have something like it. If they wanted to re-use that to create a news filtering service they probably could. On the other hand, the rest of us users would have no particular reason to believe they don't have their thumb on the scale, promoting news that serves their interests, or that they were paid to promote. So, I wouldn't say what I'm suggesting is purely a "technical solution", there are social and cultural aspects to it as well, but the one aspect of the problem -- that are human brains can't cope with large social networks -- is one that we can use computers to solve, if we have the right data.
Really? I literally read dozens of papers about it a decade ago, at least... I guess I don't work adjacent to there so maybe no one else does either. Odd, I never have heard a reason why they were all that much worse than alternatives other than for corrosion and licensing costs, I am surprised that such a well defined problem just stopped being studied.

I suppose at some point it's not competitive with solar so what's the point. Maybe we reached that threshold recently.

I haven't had time to read all of the info, but I get the impression that this is still a pressurized water reactor, just on a smaller scale. It will fail in pretty much the same way as current reactors like Fukushima and Chernobyl. I believe that the point is that the pool provides an extra level of failsafe against coolant loss, and additionally that the substantially smaller size of the core limits the amount of heat build-up in a meltdown.
I had a co-worker whose wife was applying for US citizenship. In the middle of processing her paperwork the immigration department decided they needed to paint the office. The story goes - and I believe her lawyer told her this - the immigrations employees went home one day and the painters came in and covered all of the desks with plastic. They then took the next two years to paint the facility. At the end of two years the tarps came off and the workers returned - with all of their paperwork from two years prior exactly where it had been left.

Sounds crazy but is somehow believable. I had a similar experience last time I was at the New York DMV where I handed an agent my papers, he looked at them for a bit then got up and left without saying a word, he went and had lunch for an hour, then came back as-if nothing had happened. I had twenty plus people standing behind me in the same queue. The other queues around us kept moving, we all stood there for an hour while the guy ate.

you are confusing two different characteristics of reactor design.

one is whether or not the coolant is highly pressurised relative to atmosphere, the other is what the thread was originally about, which is how reactivity changes with respect to temperature. this is the temperature coefficient of reactivity.

https://www.nrc.gov/reading-rm/basic-ref/glossary/moderator-...

the people you were responding to were referring to the latter. specifically, if a reactor becoming more reactive results in more or less total reactivity. this characteristic is related to, but independent of, how pressurized the coolant and/or moderator are.
Settings -> Privacy -> Apple Advertising (all the way down) > Personalized Ads
Yes. This is not an inherently safe design. However, it adds a second level of safety, in that each reactor has its own coolant loop that would have to fail first, followed by a second failure of the large pool. It looks like the large pool is also passive, in that it does not rely on circulator pumps to provide cooling.
If you see over 25% THC on flower is likely a bogus result, or a result of payola.
Ah, yup, on the first point I misunderstood what you meant. Apologies for reading your comment in a poorer light than it was.

We agree in some broad strokes, but seem to disagree on other points.

The original comment I wrote was contesting the idea that averaging multiple points of view necessarily mean that you're getting closer to the truth. It can mean that, but it doesn't have to if there's a shared underlying bias.

I think we'd also disagree on the value of being informed about current things similar to your example of a google anti-trust suit. I would personally expect that reading the average news article on it does not make me meaningfully more informed (since journalists digest the original court filing or whatever prompted it into a piece devoid of value in my experience).

I'd say that you get more value out of understanding the broader context: how anti-trust suits in the US generally go. In all probability, in 4 months that headline will be completely irrelevant and nothing will have happened. It's more likely that it's a clickbait bit of news churn based on a fragment of truth than that it's both true, and the implication that it's meaningful and important news for us to know is also true.
