cik2e··on The Most Counterintuitive Recession Ever
Much worse and possibly catastrophic if the government doesn’t get its shit together on the next stimulus. Now Trump gets to look like a hero with his executive orders, and honestly you can’t blame the administration for taking the easy layup. Hopefully this shames congress into doing its job because it’s unlikely that the critical unemployment benefit will be getting paid out anytime soon via this route.
cik2e··on The ‘-ize’ have it (2012)
“Most winning” would be the correct alternative, with the same number of syllables although to me it does feel more concise. As an American, I also hate this made up word.
cik2e··on Drivers who keep their windows down are exposed to 80 percent more air pollution
Slowing down to idle speed and ensuring the intersection is clear absolutely nothing like what’s being addressed in that video.
cik2e··on Dementia on the Retreat in the U.S. and Europe
Almost every automatic nowadays gives you a couple of gears to play with. I always downshift on curves or when braking to a stop. I also drive a hybrid and downshifting guarantees regenerative braking whereas with the pedal it’s easy to over do it and engage the pads.
cik2e··on American darknet vendor and Costa Rican pharmacist charged
Moderate opioid use is possible if you take long enough breaks to avoid physical dependence. That of course requires the self-discipline to say no to the psychological pull. As far as I recall, I felt some mild withdrawals after about 3 consecutive days of poppy tea use, so the physical dependence does set in pretty quickly. But if you know your boundaries, it’s easy to avoid. I would wager a guess that you could do strong opioids once a week indefinitely without any negative repercussions.
cik2e··on Men rescued from Pacific island after writing SOS in sand
I think this is more for serious wilderness hiking and camping, not a trek through a national park with designated campgrounds.

High quality backpacks and hiking boots are around $200, and tents are easily double that. If you’re going on hikes that pose a realistic chance of getting stranded, you’re probably pretty serious and already paying for premium equipment. In which case, another $300 for peace of mind shouldn’t be a dealbreaker.

cik2e··on Test-First Machine Learning
> Testing model implementation details such as statistical and mathematical soundness are not part of the TFML strategy. Such details should be tested separately and are specific to the family of the model under consideration.

For anyone who clicked this thinking this would be related to model validation, it ain't. The article is promoting test-driven development for systems that have an ML component.

cik2e··on Dance is superior to repetitive physical exercise for brain plasticity (2018)
It’s pretty obvious that the parent post isn’t saying that dance is different in that it’s not inherently competitive, but rather that sports have to be done at a competitive level to match the physical requirements of dance. And I strongly disagree with that sentiment. My claim is that sports done with deliberate practice aimed at improving technique are just like dance done with deliberate practice aimed at improving technique.
cik2e··on Dance is superior to repetitive physical exercise for brain plasticity (2018)
Here are just a few examples of sports that require continuous attention from your entire body in response to an external stimulus:

Snowboarding, downhill skiing, mountain biking, and any martial art. These are from personal experience, I’m sure there are plenty of other examples.

Even weight training, which is an experimental group in this article, when done properly, requires high levels of neuro-muscular coordination and development. I am always weary of studies that evaluate “strength training” because there are so many different approaches with wildly different outcomes. Let’s just say that a max effort squat by an athlete with around two years of proper training emphasizing technique requires a hell of a lot more coordination than busting a move on the dance floor. I’ve been weight training for 15 years and I still feel like I am learning something new every time I get under the bar with the right mindset. The mindset part is key, because if you are just going through the motions then you’re not developing new skills. But I would bet a lot of money that top level strength athletes would say that their form is far from “perfect” and that this the area that affords the biggest opportunity for improvement.

This is the part where I’m going to be brash. Unless you tell me exactly what defines a strength training regimen in your study, I will assume it’s something along the lines of curls and lunges done with tiny dumbbells over a large amount of reps. Especially if your study calls it “repetitive”. There’s nothing repetitive about proper strength training. Every rep that’s done mindfully affords a unique learning opportunity.

Sports simply too complex to categorize in simple terms like “dancing” or “resistance training”. In the context of experimental design, our definitions have to be much more precise.

Having said all that, this is how I interpret this article: “Learning complex motor skills that require high levels of attention is better for the brain than doing 100 curls with 3 lb dumbbells.” And my response to that is “no shit”.

cik2e··on LSD Chemist William Pickard to Be Released from Prison
You’re forgetting about coke, heroin and meth, and the massive amount of related violence down the supply chain.

And there is still violence associated with marijuana in CA because about 80% of the market is still underground due to the extreme difficulty of navigating the current regulations.

There is plenty of reading material on this.

cik2e··on Boeing, expecting a long slump, will cut 16k jobs
Sure, you can say behAvioral economics experiments are unreliable. But even if this field did not exist, assuming close to perfect information is simply naive in my opinion. Unless you account for insider trading, which the pessimist in me believes is rampant. In truth, none of us know, but I think it’s worthwhile to consider the alternative to what is taught in textbooks.
cik2e··on Boeing, expecting a long slump, will cut 16k jobs
That’s assuming perfect information. Behavioral economics begs to differ on that being even close to reality.
cik2e··on U.S. Economy Shrinks at 4.8% Pace, Signaling Start of Recession
This isn’t a typical recession and cannot be compared to anything in the past. The economy has been effectively put on pause. So the dynamics of the duration and recovery will be totally different than anything we’ve seen in the past. I’m optimistic about a much quicker recovery than the last one.
cik2e··on Ennui: How to Overcome Chronic Boredom
Speaking as an above average looking person (or so I’m told), I’ve found that here in my 30s, physical attraction has taken a major back seat to the personality factor. Maybe I’m in the minority on this one, but I don’t really think of people as attractive or not any more based on facial features or anything else that we don’t have control over with regard to our bodies. What matters is physical fitness and whether we can have a mutually interesting conversation.
cik2e··on Lyft lays off 17% of workforce, furloughs hundreds more
Nah, that’s not it. I drove for both in a major city in the months before the virus and outside of peak hours Lyft always has substantially longer pickup times. This is based on a few hundred rides for each company. This means that they have fewer passenger per driver, so the biggest delta is a smaller user base. Once the lockdown began Lyft rides basically evaporated overnight, while Uber was still going strong at certain times and certain places, catering to essential workers. But both are worthless as a way to make money right now.
cik2e··on Tips for Mathematical Handwriting (2007)
I was a math major and started doing all of this very quickly because I couldn’t read my own work. I would put this in the realm of common sense.
cik2e··on Vandalize Your Car
Don’t make the other guy brake is right. Sadly, this is the first time I’ve heard this said by anyone besides myself.
cik2e··on Vandalize Your Car
Are you kidding? The left lane is for passing only. Some places even have signs pointing this out to the clueless. Driving slowly in the left lane causes the fast idiots to tailgate at 80mph and swerve in and out of lanes to pass the slow idiot.

I wish US cops would enforce anything but moderate speeding and rolling through stop signs.

cik2e··on Why has examine.com disappeared from search results?
Google health related results are straight garbage these days. I noticed the change that dropped examine in the rankings as I frequently search for supplements. At the same time l, Wikipedia also tanked in my queries which is one of the sites that I’m almost always going to have a look at if they have a page on the topic. This seems tied into google’s expansion of their built-in snippets. That would be ok if they linked to the source but it feels like that’s true for only 1 in 20 of these boxes.

I’m actually really frustrated with these changes and would like to start using an alternative. I like startpage but they use google search results so that’s not a viable alternative. Guess I’ll have to check out duck duck go’s Bing powered performance.

cik2e··on Drones piloted by climate-change activists target Heathrow
> They're interested in trying to persuade more people to stop eating the flesh of sentient creatures when our diets don't even require it.

In a strict sense, you’re right, our diets don’t require meat. But most people wouldn’t consider it practical to take the 5-10 different supplements needed to replace all of the benefits of eating meat, fish, eggs and dairy. And that approach is almost certainly suboptimal to whole food sources anyway.

cik2e··on Magnesium and major depression (2011)
Glycine’s not a filler in this instance. It’s used to aid absorption [1]. Mag glycinate is one of the only worthwhile forms of magnesium for supplementation, unless you’re using it as laxative. The latter being caused by gut irritation from unabsorbed magnesium.

But yes, glycine also has many of its own benefits. Including a very interesting theory regarding life extension due to its interaction with methionine. [2]

cik2e··on I left the ad industry because of data tracking
There are many sites that have quite accurate PII for large fractions of the American population. Think job boards for instance. One approach that I have seen used successfully is simply buying whatever data such companies are willing to sell.

I’m not necessarily talking about demographics, but rather clickstream data, and anything categorical that you can get your hands on. You join that to your CRM and build a model to predict buyers. A really good predictive dataset for marketing purposes is simply a list of time stamps and names of visited domains. With the right feature engineering, that becomes an excellent proxy for demographic data, current buying appetite, and a whole lot more.

At the end of the day, you don’t even necessarily need to know what the data means as long as it’s predictive. And there are plenty of brokers out there who will let you test their data for free with an agreement to pay if you end up using it at scale. All of this revolves on using PII for matching.

I’m sure what you’re saying is true for some marketers, but there are billions being made on PII keyed data.

cik2e··on I left the ad industry because of data tracking
> There is no demand for personal data or de-anonymization because that stuff doesn't sell.

Say what?? I’ve also worked in the ad industry and deanonymized personal data is shared and sold routinely. You speak of statistics and large segments but every advertiser I’ve interacted with is either doing individual-level targeting or striving towards it.

cik2e··on Soviets say Allied version of D-Day is a 'distortion' of history (1984)
> Nor any mention of the clear delays to D Day as a direct result of the sheer quantity of war materiel sent to Russia via the Arctic convoys and through Iran.

This idea sounds patently false and I can't find a single source to support it.

According to Wikipedia, the total US expenditure on Lend-Lease was 48 billion, with 31 of those going to Britain and 11 to the USSR [1]. But saying that D-Day was delayed as a result of the sheer quantity of aid sent to Britain would still be incorrect. Nearly the entirety of Soviet economic aid during the war can be attributed to the U.S. It provided the bulk of the actual raw materiel and effectively paid for the rest through the funding British production. Now combine this with the fact that Roosevelt and his advisors were pushing to open up the Western European front in 1942, a year after Lend-Lease had gone into effect, with Churchill winning out in opposition to the idea. It simply doesn't make sense that the cost of aid to the Soviet union was even part of the equation.

cik2e··on Yale's online class on “The Science of Well-Being”
The trope of "money doesn't create happiness" applies only to people who already have their financial freedom. I completely agree that aspiring to get a bigger house or a nicer car when you already have a big house and a nice car is pretty shallow and speaks to an underlying inferiority issue that more money won't cure.

The rest of us on the other hand would be anywhere from a little to much much happier if we had student loans, mortgages, kids' educations, and retirement savings all taken care of.

The prospect of having to slog through life in a glacial pursuit of these things fills me with dread. For me there isn't much of an option beyond becoming successful as an entrepreneur. It's not even so much about the money but having complete ownership. Having to work until 65 running a mildly successful business that I built seems like it shoild be much more gratifying than slaving away to enrich others.

cik2e··on Inflammation might be the root of preventable disease
I don't get why you're so resistant to the idea that sytstemic inflammation (not gingivitis) can simultaneously be a symptom of one condition and the primary causal factor in many others. The article gives plenty of examples of conditions where inflammation does seem to be the root cause. It feels like you haven't read it, in which case I highly recommend doing so. It's quite educational and not not at all biased towards a big-pharma solution.

The article also gives sound reasoning for why metabolic stress, i.e., overeating, eating crap and not exercising, could be the most common cause of chronic inflammation. I would guess that psychological stress is another big factor given it's known ability to exacerbate autoimmune and inflammatory conditions. So the cure for most cases of chronic inflammation is going to be the usual mix of diet, exercise, sleep and stress management. We already know that these are the most effective preventative measures against age-related diseases and this research gives us a better understanding of the underlying mechanics.
