brational··on The Presence of One’s Own Smartphone Reduces Available Cognitive Capacity
Depends on your family situation but android/ios phones shuold all have a DND mode that you can put on a schedule and allow exclusions for "favorites" or something of the sort. I have mine on DND from bed time through end of work day with only the wife and immediate family excluded. leave it in a bag or out of site and only check it at defined breaks. strikes the balance for me.
brational··on The Presence of One’s Own Smartphone Reduces Available Cognitive Capacity
same - except my DND is set for midnight until 4pm. i still check the phone at lunch or when i get to work but i otherwise wont notice it unless it actually rings.
brational··on Weight Training Is the Best Exercise for Bone Strength
There's separate research as well into how much, if any, exercise can slow/reduce Sarcopenia (https://en.wikipedia.org/wiki/Sarcopenia). So they are at least researching it separate from simple correlation as well.

"Exercise is of interest in treatment of sarcopenia; evidence indicates increased ability and capacity of skeletal muscle to synthesize proteins in response to short-term resistance exercise.[18] A 2009 Cochrane review also found evidence that in older adults progressive resistance training can improve physical performance (gait speed) and muscular strength,[19] which are two key components of sarcopenia."

brational··on L.A.'s crisis: High rents, low pay, and $2k doesn't buy much
If I read you correctly you're essentially suggesting that someone living in a low-cost of living area isn't paying enough for the shipped products they receive by way of major transport hubs?

I'd argue that's slightly evened out by prices that don't fluctuate as much by location. ex: In my midwest city I own a 3br 1500 sqft house that cost 190k and my wife and I gross over 160k. In an SV or Seattle type area we could be double the income and 10x or more for same house so it seems like we're getting a sweet deal right? But plane tickets, automobiles, many smaller consumables, anything you can buy on amazon, higher priced hobby items (phones, road bike, etc), are relatively inelastic to location. So we pay a larger share of our income than if we lived in a high-income area. To a certain extent, fuel as well. I regularly travel to chicago, seattle, and intermittently to LA area and gas prices are only marginally higher than in my low tax red state. While not so static, the cost is a bit baked in there as it's a larger proportion of my income to fuel my car.

That said, I'd have to put real numbers into this to see if my counter argument holds. You may be right that we underpay at a macro level and have some arbitrage. Your message just seemed to suggest it was obvious which I don't think is the case.

brational··on Don't use Hadoop when your data isn't that big (2013)
That's maybe a bad example as those companies all actually make use of the more expensive infrastructure.

A better question is what ROI does generic non-tech enterprise company X get from standing up a huge data science team for simple data management problems.

brational··on How to Become a ‘Superager’
you seem to be of the opinion that because concussions are bad, the idea of exercise aiding aging or other mental benefit isnt supported? that's absurd. there's significant evidence of the benefits of physical activity to mental health. which is pretty obvious considering that muscle contraction is entirely driven by the CNS.

here is some study into these various ideas. google your heart out but this was the first i found.

brational··on Homeschooling as a right, and a needed practical alternative
I took the salt lake effect to mean that the students left in the public school no longer have a potentially intelligent (emotionally and/or socially) peer with which to interact. As has been stated ad nauseam, kids learn a ton from their peers, especially the ones they view as strong/confident/talented.

When "smart" parents remove their kids from the public school, the public school is worse off from having lost the student and parent would could have helped provide a better environment.

brational··on Donald Trump Is Elected President
In a non-argumentative tone though, that poster's point was that your ideas have been tried, are being used, and it isn't a viable solution. As someone in a red rust belt state, it HAS been the approach. There is constant attempts to attract companies out of the hubs but it just doesn't work because you can't find the correct mix of people for X location.

Me too - for me the difference is early retirement isn't really feasible in Europe. The exception being maybe get a remote job in the US and then move. Haven't succeeded there yet.

brational··on Classism in America
This is widely true in a lot of other engineering disciplines, especially those that are more hands-on. Anecdotally, in certain parts of the country this is why engineers (think mechanical, civil, etc) are viewed a large step below "true white collar management" types.

Title: Being a ‘Dumb’ Girl in Computer Science

Title should be: Being ‘Dumb’ in Computer Science

Well, doctors are just "practicing medicine" after all...
brational··on Being a “dumb” girl in Computer Science
> Namely, that everyone feels that they're the dumb one in a room full of brilliant effortlessly successful people, and that if the coursework is not easy and a little boring you should quit because it only gets worse from here.

So I self-learned CS, my degrees were in applied math, and it was similar in the math world. Although more like:

"everyone feels that they're the dumb one in a room full of other dumb ones... "

But where I studied, we did receive that sort of lecture early on. That "a wall" as you've described it is normal, get used to it.

It's served me well, being comfortable with "not knowing" something. You could argue that it's something every student of ANY subject should be told but I guess many subjects are easy enough that simply working at X% effort is enough to never get stumped.

brational··on Developers, Being Treated Poorly? You Are Not Alone
> I wonder if the author was raised in a very different culture, either because he or his family was of foreign origin, or he was simply brought up with an atypical set of cultural cues and values. These can be very difficult to uproot, and may explain the sense of bumbling through professional situations that the article conveys.

This is what I thought as well. The author's perceptions of reality seem a bit "off" and even naive in some cases.

I don't think that's an accurate comparison. There's not really anyone in the healthcare industry that would argue against vaccines but there are plenty professionals with qualification (mds, pharmacists, etc) that are against the broad use of statins.

brational··on The Starfighter Low-Level Tech Tree
I guess you could consider this a noob question. I'd like to get into this and more low level stuff in general.

Background:

I'm an applied math guy that works in cv, image processing, and anywhere that stats & optimization can be used. Work has recently led to learning more distributed stuff, albeit simply wiring up zeroMQ with c++ or python and getting the concurrent dances right.

Is it safe to say that Microcorruption is sort of a pre-req to this? Should I muck around in there first for a bit or sign right up for starfighter? Thanks.

brational··on Live longer, work longer
I'd argue that this is exactly what blue collar america used to be before manufacturing up and left. That and 30-40 years of productivity gains not distributed to workers.
